12.05 Printing on swellpaper (microcapsule paper)

Swellpaper (also called microcapsule, puff or fuser paper) is a heat sensitive paper and contains chemical ingredients that swell up to form a raised texture. Whereas braille embossers will use lines made up of individual braille dots, designs printed on swellpaper have more fluid, continuous lines that retain more detail.
Once the design has been printed with an inkjet printer, the paper has to be heated in a special oven in order to produce the braille texts and tactile images. In this process, any areas on the paper with black ink will swell to form the relief.
Laser printers are not recommended for swellpaper as the high-temperature environment can cause the paper to swell inside the printer, resulting in a serious paper jam.

Optimise braille dot diameter
Swell-paper produced by various companies (such as Tangible Magic Paper, ZyTex, Flexi-Paper and Matsumoto) are all suitable for tactile graphics. Each brand has slightly different properties in terms of the required temperature and duration of heating. It takes some experience to find the optimal settings for the particular paper that you are using, so make sure do some thorough tests to find out which combination of temperature and heating time works best.
Depending on the oven temperature, the braille dots might raise either too much or not sufficiently, making them no longer distinguishable as individual braille dots. To compensate for this effect, the diameter of the dots can be adjusted by choosing ‘Text label presentation: on print’ from the Settings menu and increasing or decreasing the size of braille dots.

Printing text combining visual font with braille
The normal font (visual characters) of braille labels can be printed in a lighter colour. To avoid the text being raised when heated in the oven, make sure to select a colour other than black in ‘Text label presentation: on print’ as the ‘Text colour on print’. For example, a green or blue works well for visual readability.

1.04 Installing updates and beta versions

TactileView version 2.200 – release notes

TactileView designs can now be inserted in Duxbury Braille Translator (DBT) documents! You can read more in our software manual section on TactileView and DBT.

Version 2.200 also saw the introduction of dot view as an alternative to the line view. You can find out all the details in the software manual section on dot view and line view.

Apply filters on a selected area

Previously, filters could only be applied on the entire design. In version 2.200, filters can now be applied on a selected area. To apply this, choose ‘Select Area’, then ‘Select Rectangle’. In the design, make a selection of the area on which you wish to apply a filter. Once you have made your selection, you will find the list of available filters in the right vertical toolbar.

8 dot braille supported

In previous TactileView versions, only 6 dot braille was available. In version 2.200 the 8 dot braille tables from the list of LibLouis braille tables is also supported. For example, this allows you to use braille notation in your designs matching the braille on a braille display. 8 dot braille can also be entered with braille keyboard input when your keyboard supports pressing up to 8 keys simultaneously.

When an 8 dot braille table is selected, you can choose to reduce the line height for lines of text that do not contain braille characters with dots 7 and 8. The line height will then be reduced to the size of 6 dot braille to save space. You can determine your preferences and select an 8 dot braille table via menu Settings > Braille Tables.

Mathematical notation in braille

In the previous release of TactileView, mathematical notion in braille was introduced. The list of available notations has now been extended with LaTeX and Dedicon (for Dutch users) as output in braille. You can simply enter your equation and automatically convert this into the selected mathematical braille notation.

You can select your preferred mathematical by choosing ‘Mathematical notation (equation editor) from the Settings menu. When your preferred notation method is not in this list, you can use the ‘linear text’ option to display the equation in your braille table as it is entered.

Adding or removing an area

Adding or removing a vertical or horizontal area in the design has been simplified. You can find this function by choosing ‘Select Area’, then ‘Insert or Remove Space’ (previously, this was one of the functions of the rectangular selection). To make a horizontal or vertical selection, click in the design for the first position, then hold and release for the second position; alternatively, you can also click two times to determine the two horizontal or vertical edges of your selection.

Two green dotted lines will show the edges of the selected area. You can drag these lines to adjust them. On these lines, a green plus and red minus sign allow you to add or remove the selected area of the design. By moving with your mouse over these signs, you will see a preview of adding or removing the area. Once you are satisfied with the placement of the selection, simply click on the plus or minus sign to confirm.

Embosser support extended

– Enabling printer support has been extended, including the Phoenix Gold model.

– Index Braille has released a new version of the printer driver for their V3 model range. This means that for both the V3 and V4 models, you can now use their printer driver for tactile graphics and no longer need to install the TactileView driver for V3 models.

– Print results for ViewPlus printers have been improved to give sharper lines and avoid small unwanted dots due to noise in the design.

Smaller changes

– The functionality for inserting svg images has been improved; for example, texts in svg’s are automatically converted into braille, including rotation when supported by your embosser. In the left vertical toolbar with drawing tools, inserting svg’s, other image files or figures have been grouped together.

– In TactileView designs, the right-up marker is automatically printed by default as a convenient indication of the page orientation for the VIP reader. This right-up marker is now visible on screen as well. It can be switched on or off when necessary by clicking on the red marker in the top right corner of the design.

– The size of the pen or eraser tool can now be changed using a horizontal slider. Alternatively, you can use the scroll wheel on your mouse while holding Shift to adjust the tool size. We have also added the choice between a round or square shape for more accuracy.

– The ‘Text label presentation’ dialog in menu Settings has been divided into ‘Text label presentation: on screen’ and ‘Text label presentation: on print’ to make a clearer distinction. Please keep in mind that these two representations can differ: e.g. you can choose to hide braille on screen for improved readability, but the braille will still be embossed when you do not disable it on print as well.

– When adding text labels, you can now type the contents directly in the design instead of in a text field in a dialog. This gives you better feedback about the placement and alignment of the braille text. The remainder of the options that were available in this dialog, such as braille table selection, can still be accessed via the right vertical toolbar.

– When you open an image file (.jpg, .png, svg, …) as a new document, the image will no longer be fused with the bitmap but will be inserted as a figure. This gives more control over the size and position of the image.

– Image files can now be copied directly from any folder in Windows Explorer and paste it in your design as a figure. You can also browse for any saved image file by selecting ‘Add figure’ from the drawing tools toolbar, then choosing ‘Import image from file’. You can also find this option in the File menu.

– The horizontal toolbars have been rearranged slightly to give easier access to functions that beforehand were only available using the menus.

– A selected area can be rotated or mirrored by clicking on one of the four small icons around the selection. Combined with the aforementioned filters, this gives a more direct way of manipulating the contents of your design.

– Text labels automatically have a small white area behind the braille which covers all elements in the design to ensure there is enough space to properly read braille. However, in some cases such as text labels spanning multiple cells in a table, it can be useful to remove this white space. A transparent label is indicated with a white centre in the green, orange or blue-grey bullet in front of the label. Keep in mind that with the white space removed, lines can interfere with the braille text, so ensure there is sufficient spacing around the text label and no overlap with any lines.

– When placing blue dots, you can determine the size by scrolling with the mouse wheel while holding down Shift. The cursor will indicate the size of the dots that will be placed.

– For polygons and freehand lines, you can now choose between straight and curved lines between the anchor points. This allows you to make use of nice rounded curves in your designs.

– When you draw a polygon or freehand line you have the choice to close the shape (by clicking on the first marker) or to leave the shape open without a connection between the first and last markers (press Escape or choose ‘Finalize the polygon’ from the toolbar or context menu). When the polygon is open, you can easily continue drawing by clicking on one of the two green plus signs at either end point of the open polygon.

– Empty text labels will be removed automatically when deselected.

– For more convenient zooming using Ctrl+scroll wheel, the design will now stay centered on the position of the mouse.

– An additional step was added to the Configuration wizard in which the use of external software (currently MathType and Duxbury Braille Translator) can be configured.

– For some specific applications (e.g. printing on swellpaper) applying a colour to an object can be useful. You can give the blue object a colour by selecting Fill Style: Colour. To remove this colour, select white as fill style.

– The textures that can be applied to objects have been improved for better consistency and tactile usability. The ‘Fill Style: Texture’ dialog has been adjusted to make it easier to determine the right properties for the texture.

– Extra markers were placed on the edges of a triangle which allow you to scale the entire triangle, maintaining the proportions/angles.

– Previously, when a texture or line style was selected for an object, any newly drawn objects would get the same texture or line style. In the new version this is no longer the case in order to avoid having to manually switch off these properties for new objects.

– The command for rotation of objects or text labels has been changed slightly from only using the scroll wheel to holding down Shift+scrolling. This avoids repeated unintentional rotation when you want to scroll through the document. Use Ctrl+Shift+scroll wheel for more accurate rotation per 1 degree.

– The latest releases of the Liblouis braille tables (Liblouis 2.6.3 and Liblouisudtml 2.6.0) have been included.

Bug fixes

– Some problems with fusing or moving a table with text labels inserted have been solved.

– Mirroring a selection multiple times no longer causes incorrect rotation of the selected area.

– Some issues with processing production requests (teleprinting) solved and functionality extended.

– Transparency in images copied from web pages no longer

– Some issues with alignment when printing on certain paper sizes using Index printers have been fixed.

4.01 The 7 ways of creating a design

In TactileView, there are various ways of creating a tactile design, depending on the type of content you wish to create. For certain types of designs, specialised modules have been included in the software.
All 7 methods described below can be combined whenever needed in your designs.

1. Use premade designs from the TactileView catalog
The TactileView catalog contains thousands of premade designs, ready to be printed and used. Designers have uploaded the tactually usable designs they created. You can search for a particular design that you want to use, download it and make modifications needed before you produce them.
You can visit the TactileView designs catalog by selecting ‘Download and edit design from catalog’ from the Portal menu, or by clicking on the catalog icon in the top menu bar.
‘Download and edit design from TactileView catalog’ icon: Catalog icon
2. Convert images from the internet
On the internet you can find an almost endless amount of images, many of which are suitable for production as tactile graphics. For some images only a minimum of effort is needed to adapt the image. By selecting the right image as a source, such as a line drawing instead of a more complex photo, a simple combination of applying filters and minimal use of retouching tools can be sufficient.
Editing an image from the internet

3. Convert scanner and webcam images
Images taken with a webcam or scanner can be used as a source for a tactile graphic. In most cases, the images that you scan or photograph will need to be processed for tactile use. By combining the filters and retouching tools, colours can be removed and the image converted to a line drawing. In the settings menu you can configure the setup for a scanner or webcam for the software.
‘Activate webcam’ icon: Activate webcam icon
‘Quick scan with scanner’ icon: Quick scan with scanner icon
4. Create a design from scratch
With the series of drawing tools in the left vertical toolbar, a design can be partially or completely drawn from scratch in a blank design. This method often requires a little more effort than the previous three, but it gives the most flexibility in case no suitable images are available as a basis for your design.
Most designs require a combination of different drawing tools. The objects (indicated in blue) for example, give great precision and access to convenient properties such as textures. Text in the correct braille table can be added anywhere in the design as clarification. Special symbols can easily be added from the figures library.

5. Create graphs based on an equation
Graphs are widely used in mathematics and many other subjects, but there are a lot of factors that determine the tactile usability of a graph. The mathematics module in TactileView will help you to easily create a graph based on any given equation. This module can be accessed by selecting the Graphs menu or the Graphs icon in the left toolbar.

6. Create tactile maps
Producing maps of an area of any size (part of a city, region, country or even a continent) can be done with the map maker module in TactileView. Select ‘Compose map’ from the Portal menu, or click the map icon in the top toolbar.
The maps are composed on the RouteTactile website by selecting the area you wish to include in the map or which features (streets, rivers, buildings, etc.) should be included. Keep in mind that including more elements will increase the complexity of the map.

7. Combine text and graphics in one document
Texts can be included in TactileView documents, but for some purposes it is required to have a document where the graphics are part of a text book. The graphics can then be inserted in a braille editor such as Duxbury Braille Translator (DBT).

10.03 Drawing tools – Menu driven design (Ctrl+L)

TactileView is designed to allow the user to create and edit objects solely through the use of the menus, a feature referred to as ‘menu-driven design’. This method of creating graphics takes some practice, as you must decide where to place objects based on the distance of a specified critical point for each type of object away from the top and left edges of the design.

Menu-driven design may be used to edit existing graphics or to create new ones. This tutorial describes common functions for adding and editing objects in a drawing.

Adding objects

The drawing tools have been designed to use a coordinate-based drawing system. This means that each time you select a drawing tool, a dialog will appear that lets you specify the location in which the object will be inserted by inputting position and size information for that object.

Drawing straight lines

To draw a straight line, choose the ‘Draw Straight Line’ option from the Drawing tools menu. This will bring up a dialog allowing you to specify the position of the start and end points of the line you want to insert. Fill in the horizontal and vertical positions for the start and end points and enter the desired line length, then choose the ‘OK’ button to close the dialog and insert the line.

Drawing squares and rectangles

To draw a square or rectangle, select the ‘Draw Square-Rectangle’ option from the Drawing tools menu. This will bring up a dialog allowing you to specify the size and position of the square or rectangle you want to insert. Fill in the desired position of the upper left corner of the shape. To specify the size, first choose the Enlarge/reduce radio button if you want to insert square or the Stretch radio button if you want to insert a rectangle. Specify the width of the object. If you are inserting a square, you do not need to specify the height. If you are inserting a rectangle, enter the desired height of the object. Select the ‘OK’ button to close the dialog and insert the object.

Drawing circles and ovals

To draw a circle or oval, choose the ‘Draw Circle-Ellipse’ option from the Drawing tools menu. The dialog that comes up allows you to specify the size and position of the circle or oval you want to insert. Enter the position of the center of the circle. Next, choose either the Enlarge/reduce radio button to create a circle or the Stretch radio button to create an oval. Specify the width of your object. If you are inserting a circle, you do not need to enter the height. If you are inserting an oval, enter the desired height of the oval. Select the ‘OK’ button to close the dialog and insert the object into your file.

Drawing polygons

To insert a polygon, choose the ‘Draw Polygon’ item from the Drawing tools menu. A dialog appears, allowing you to enter the number of points you want in your polygon and define their positions. By default the polygon starts with three points. Select each point from the anchor points list and specify its location. The software calculates the angle from the previous point and the distance to the previous point for you. You can add more points by choosing the ‘Add anchor point’ button, and you can remove unnecessary points by choosing ‘Delete anchor point’. When you are finished, choose the ‘OK’ button to close the dialog and insert the shape.

NOTE: Points in the polygon can be added and deleted later when editing the shape with either the context menu options or the mouse.

Drawing triangles

To insert a triangle into your drawing, select the ‘Draw Triangle’ option from the Drawing Tools menu. The dialog that appears allows you to select the type of triangle you want to insert (right, isosceles, equilateral or scalene) and enter the positions of the points of the triangle. Select each point from the anchor points list and enter the desired position. The software calculates the length of each line segment touching the point, as well as the angle between them. When you are finished, choose OK to close the dialog and insert the triangle into your file.

Adding arows and other figures

To add arrows or other commonly used shapes, choose ‘Add Figure’ from the Drawing tools menu. A dialog containing a list of available figure categories including arrows, electrical symbols and more appears. (NOTE: You can also add your own commonly used shapes as figures so that you can easily insert them into files. Please refer to the Adding Figures to the Figure Library tutorial for more information.) Browse through the categories and select a figure to add, then choose ‘OK’.

Next a size and position dialog appears, allowing you to specify the position of the figure in your drawing. Choose the Enlarge/reduce radio button if you want to lock the object’s height with respect to the width when choosing the size, or choose the Stretch radio button if you want to define the width and height separately. Choose the ‘OK’ button to close the dialog and insert the object into your file.

Drawing freehand lines

A true freehand line can be drawn accessibly using the digital pen with the software. However, you can draw a line or closed shape point by point with the menu-driven design by choosing the ‘Draw Freehand Line-Closed Shape’ option from the Drawing tools menu. The same dialog that appears for the ‘Draw Polygon’ function appears for drawing freehand lines, allowing you to enter the number of points you want in your line or shape and define their positions. By default the line or shape starts with four points. Select each point from the anchor points list and specify its location. The software calculates the angle from the previous point and the distance to the previous point for you. You can add more points by choosing the ‘Add anchor point’ button, and you can remove unnecessary points by choosing ‘Delete anchor point’. When you are finished, choose the ‘OK’ button to close the dialog and insert the shape.

NOTE: Points in the line or shape can be added and deleted later when editing it.

Text labels

You may add text format labels to a file at any time. There are several formats of labels available for use in TactileView. The most commonly used type of label in TactileView is referred to simply as a ‘text label’. Text labels may be entered in plain text and be automatically translated to braille when they appear in the document, or they may be entered directly in braille through six-key input.

In addition to text labels, TactileView offers the option to add mammoth braille labels or print character labels that will be embossed as raised text.

NOTE: Labels may only be edited according to the input method used to create them. For example, a text label entered via braille (six-key) input may only be edited using six-key, and a raised print character label may only be edited as a raised print character label. Labels can’t be converted from one type of label to another.

Adding text labels

The most commonly used type of label in TactileView is referred to simply as a ‘text label’. Text labels may be entered in plain text, and then they are automatically translated to braille when they appear in the document.

When using menu-driven design, text labels can be added either by choosing ‘Add Text Label’ from the Drawing Tools menu of the software, or by opening the List of Objects (Ctrl+L), choosing the ‘Add Text Label or Object’ button and selecting ‘Add Text Label’ from the list of options.

A dialog will appear, allowing you to enter the text for your label, select the braille table to use for translation and input position information.

Enter the text you want to use in your label into the Contents box. Select the braille table to use for translation from the Select Braille Table for this Label combo box.

Enter the location for the text label by editing in the Distance to Left Edge and Distance to Top Edge fields. You can also control the width of the text label by specifying the maximum number of characters you’d like it to have before the text wraps to the next line. Choose ‘OK’ to close the dialog and insert the label.

Adding text labels through six-key entry

Currently this option is only available accessibly through the use of the digital pen. Please refer to the Accessible Drawing Using the Digital Pen tutorial.

Adding mammoth braille labels

When using menu-driven design, mammoth braille labels can be added either by choosing ‘Draw Mammoth Braille’ from the Drawing Tools menu of the software, or by opening the List of Objects (Ctrl+L), choosing the ‘Add Text Label or Object’ button and selecting ‘Draw Mammoth Braille’ from the list of options. In the dialog that appears, enter the text you wish to appear in mammoth braille and specify the position in which it should be inserted. Choose ‘OK’ to close the dialog and insert the mammoth braille label into your file.

Adding raised print character labels

When using menu-driven design, raised print character labels can be added either by choosing Draw Letters and Digits from the Drawing Tools menu of the software, or by opening the List of Objects (Ctrl+L), choosing the Add Text Label or Object button and selecting Draw Letters and Digits from the list of options. This launches a dialog that allows you to enter the text you wish to appear as print characters and specify its location in the drawing. Set the options as desired and choose ‘OK’ to close the dialog and insert the label into your file.

Editing objects

Selecting objects

To select an object in the current drawing, open the List of Objects dialog either by choosing Menu Driven Design from the Drawing Tools menu (Alt+T, then M) or with the hotkey Ctrl+L. The List of Objects dialog shows the complete list of drawing objects in the current drawing by object type and gives identifying information about each object. To select an object, arrow through the list until you locate the object you want to work with.

If, after selecting an object, you select the OK button on the List of Objects dialog, the dialog closes and the object you chose is selected. However, most common editing functions may also be performed directly from the List of Objects dialog, and this is the recommended method when using menu-driven design.

Copying, pasting and deleting objects

To copy an object, first press Ctrl+L to bring up the List of Objects dialog. Locate the object you wish to copy, choose the Open Context Menu button and select Copy. The object has now been copied to the clipboard.

To paste an object from the clipboard, choose Paste from the Edit menu (Alt+E, P) or press Ctrl+V. This pastes the object centered at the upper left corner of the design.

To delete an object, first press Ctrl+L to bring up the List of Objects dialog. Locate the object you wish to delete, choose the Open Context Menu button and select Delete.

Moving and resizing objects

Select the object you wish to move or resize from the List of Objects dialog and choose the Open Context Menu button. The context menu is slightly different depending on what object type is selected, but the position dialog can always be accessed through the first context menu item, which will be Size and Position, Text and Position or Positions of anchor points. Select this item to bring up the same dialog used to create the object initially, in which you can enter new locations for critical points in the object if you wish to move the object, or enter new height and width settings for objects if you wish to resize them.

You can also center an object horizontally in the drawing by selecting it, choosing the Open Context Menu button and choosing Center. This will only automatically center the object horizontally; it will keep the same vertical position on the page.

Rotating objects

Select the object you wish to rotate from the List of Objects dialog, choose the Open Context Menu button and select Rotation. On the dialog that appears, enter the desired angle of rotation in degrees and choose OK to rotate the object.

Changing object line properties

Select the object you wish to edit from the List of Objects dialog, choose the Open Context Menu button and select Line Style. This opens a dialog from which you can set the line properties for the object, including the line pattern (solid or dashed) and thickness. The drop-down list for the line pattern describes the number of pixels of black + the number of pixels of white that make up the line. For example, 2+2 means that the line will have two pixels of black followed by two pixels of white, while 5+3 will have five pixels of black followed by three pixels of white (so that the line is a pattern of longer black lines with shorter white spaces in between). Once you select the line patter, choose the thickness of the line in pixels. Choose OK to apply your changes to the object and close the dialog.

Changing object fill properties

Select the object you wish to edit from the List of Objects dialog, choose the Open Context Menu button and select Fill Style. This opens a dialog from which you can set the fill properties, including selecting a fill texture, scaling the size of the fill tiles and rotating the texture within the object.

If you would like to add a fill texture to your object, select the Use Texture Fill radio button. Choose the Change Texture button to bring up a dialog containing a list of textures that can be used. Select a texture from the list of options and choose OK. Use the Tile Size in Pixels edit box to scale the texture larger or smaller. You can also rotate the texture using the Texture Rotation Angle edit box. When you are finished making changes, choose OK to apply the fill to your object.

Adding audio labels

Audio labels are a great way to add more information to a drawing without having to make it larger to accommodate more text or graphical information. The audio information is accessed by using the file in explore mode, either on screen with a mouse or on a tactile copy on the Clickpad or Tactipad with the digital pen. For more information on explore mode, please refer to the Using Explore Mode and Using the Pen in Explore Mode with the Clickpad or Tactipad tutorials.

Audio labels can be added to any type of drawing object in TactileView, and to mammoth braille or raised print character labels. Audio labels may not be added to text labels, because text labels are automatically voiced by text-to-speech when the file is used in explore mode.

Adding an audio label to be voiced by text-to-speech

Select the object you wish to add an audio label to from the List of Objects dialog, choose the Open Context Menu button and choose Audio Style. This will launch an audio label dialog, the top section of which allows you to specify the text to be voiced by synthetic speech from one of several sources.

In the “Text or document in synthetic speech (TTS) section of the dialog, the default choice is the Self Defined Text radio button, which allows you to type the text you want voiced into the text field on the dialog. If you have text saved in a text file that you would like voiced instead, you can select the Text from Local File radio button, then choose the Browse button to browse to and select your text file. Once you have specified the text, you can check how the label will sound by selecting the Test Audio Label button. When you are finished making changes, choose the OK button to close the dialog and apply the audio label.

Attaching an existing sound file to an object

You can also attach an existing sound file to an object to have it played when the object is clicked while the file is in explore mode. To do this, select the object you wish to add an audio label to from the List of Objects dialog, choose the Open Context Menu button and choose Audio Style. This will launch an audio label dialog, the bottom section of which allows you to specify a sound file to play when the object is clicked in explore mode.

In the “Insert sound sample from” section of the dialog, the default choice is the Local File radio button, which is the one needed to attach a sound file to the object as a label. Select the Browse URL button, locate the sound file you would like to use on your computer and select it. The file path to the sound file will now appear in the text field below the sound file type selection radio buttons. You can check how the audio label will sound by selecting the Test Audio Label button. When you are finished making changes, choose the OK button to close the dialog and apply the audio label.

NOTE: If you have both a text-to-speech audio label and a sound file audio label attached to the same object, the text-to-speech will be voiced first and the sound file will play after it.

Recording an audio label from a microphone

Audio labels recorded from a microphone are played when the object is clicked with the mouse or digital pen while using the file in explore mode. Recorded labels are played after any text-to-speech labels are voiced.

Before recording, you will need to ensure that you have a microphone connected to your computer. When you have connected a microphone to your computer, you can record an audio label for an object by selecting the object from the List of Objects dialog, choosing the Open Context Menu button and selecting Record Microphone. An Audio Recording dialog appears, allowing you to select the microphone from which you wish to record, the format in which to record the sound, the location in which to store the recording and the volume percentage at which to record. To begin recording, choose the Start Recording button. To stop recording, press enter. To play back your recording, choose the Play Recording button. If you wish to re-record your audio label, just repeat the recording process. Only the most recent recording will be attached as the audio label for the file.

NOTE: Each object may only have one text-to-speech audio label and one recorded or sound file audio label associated with it. If you record an audio label for an object, it will replace any existing sound file you may have associated with that object previously.

Editing an existing audio label

You may edit any type of audio label by repeating the steps used to create the audio label.

8.05 Graphing multiple lines

TactileView provides the ability to graph four or more formulas at the same time. In the ‘Creating a graph‘ section you can read how to prepare a graph with a single formula, to which you can add additional formulas as described below.

Adding a formula

Select the graph in your design to which you wish to add a formula. Similar to creating a new graph, when adding a formula you need to choose which input method you want to use: you can either enter the formula with MathType as an equation editor, or use the keyboard to enter the formula. From the properties toolbar or context menu of the selected graph, choose ‘Add function: keyboard input’ or ‘Add function: equation editor’. In the dialog that appears, you can enter your new formula in the same way as when you created the graph.

Notice that by default a dashed line style is selected to distinguish the different formulas from each other, but you can change this to Line, Dot or Long/Short Broken if you wish. It is recommended to choose a different line style for each formula you enter. The legend above the graph shows which formula corresponds with which line style. On screen, four different colours are used to easily distinguish between the formulas.

You can apply any changes in the graph preview on the right side of the dialog at any time by choosing the ‘Apply’ button. When you are satisfied with the selected options for the new formula dialog, choose the ‘OK’ button to save your changes, close the dialog and update your graph. In the properties toolbar you will see that the icon for ‘Formula 2’ is no longer greyed out, indicating that a second formula is present in the graph.

You can add a third or fourth formula by following this same process after selecting the graph and choosing ‘Add function: keyboard input’ or ‘Add function: equation editor’ from the properties toolbar or context menu. If you wish to include more than four formulas, you will need to add the remaining formulas to one of the first four, seperated by a semicolon: e.g. sin(x^2);cos(x^2). These will be plotted as seperate lines, but with the same line style and other properties.

Different line styles such as dashed or dotted lines are used to distinguish different formulas in a graph.

8.02 Text label – Math input (equation in braille)

Currently, there are three options for entering a mathematical text label in your TactileView design:

  1. Enter the equation in a regular text label, using the corresponding braille table;
  2. Use six-key entry (braille keyboard) to directly enter the math in braille;
  3. Enter the mathematical expression using a math editor (MathType).

Options 1 and 2 require knowledge about the mathematical braille notation you are using in order to enter the equation correctly. Option 3 allows you to enter math and convert it automatically to the desired notation in braille, but this requires MathType as a math editor. In the upcoming service release, a fourth method will be included, which allows you to enter the equation in linear notation and have it converted automatically (i.e. this will not require knowledge of the braille notation or a mathematical editor).

1. Using a regular text label

When you know the rules of the mathematical braille notation you wish to use, you can use a regular text label to enter it in your design. Select ‘Add text label’ from the drawing tools icon bar, then select ‘Text and position: computer keyboard input’ from the properties toolbar. Click in the design where you want to place the equation. Make sure to include the correct spaces, parentheses and other specific aspects of the mathematical notation. MathType is required when you wish to use symbols that are not on your keyboard.

Next, make sure to select the correct braille table for the notation you are using. You can select the braille table by choosing ‘Select braille table’ from the properties toolbar or context menu. The following braille tables are recommended for the different mathematical notations:

  • nemeth.ctb for Nemeth;
  • ukmaths.ctb for UKmaths;
  • marburg.ctb for Marburg notation;
  • en-us-comp8.ctb or similar for LaTeX;
  • Dutch braille table for Dedicon notation.

2. Using six-key entry

If you know the mathematical braille code and wish to simply use braille keyboard (six-key) entry for direct input of the desired characters, please refer to the ‘Different types of text labels‘ section for instructions on adding text labels through six-key entry.

3. Equation with math editor (MathType)

You can use MathType as a math editor to automatically convert the entered equation to the desired braille notation. The math editor is also required to enter math that is too complex to be entered in linear format or when symbols are required that are not available on the keyboard. For more information on using MathType to enter mathematical expressions, please visit their website.

Once you have entered the equation in MathType, select it and copy it to the clipboard (Ctrl+C). Switch to TactileView, select ‘Add text label’ and choose ‘Text and position: math input’ from the properties toolbar. Click in the design where you wish to position your mathematical label.

In the dialog that appears, select the preferred mathematical notation and click on ‘Paste math equation from clipboard’. The equation will now be displayed in both visual (linear and spatial) and braille format.

The dialog also allows you to adjust the location in which you would like to insert the label (if different than where you originally clicked in the file) by filling in the distance fields. You can size the label by specifying the maximum number of characters you would like it to have before the text wraps to the next line. Choose ‘OK’ to confirm and close the dialog.

Mathematical text labels may be moved and edited the same as other text labels. For more information, please refer to the ‘Editing text labels‘ section.
