Functions of the digital pen in the design mode and in the explore mode

In this section, the basic operation of the different products is described. In separate sections, the functionality will be explained when the pen and receiver are connected to create a drawing (design mode) or exploring a audio-tactile diagram (explore mode).

TactileView digital pen

The digital pen enhances the functionality of the TactileView software for a visually impaired user. It replaces and extends the use of a regular mouse.

The digital pen acts as a mouse to operate the software (by clicking opening menus and selecting options) or as a pen in a bordered area, similar to a digitizer.

The digital pen itself resembles an ordinary ballpoint pen. In the tip we can find a tiny transmitter that transfers a signal to a receiver. The receiver is placed alongside the TactiPad or the ClickPad and is connected via USB to the computer. Via the receiver, the position of where the pen is within the surface of the pad is transmitted. Just like a regular mouse, you can click by pressing down with the pen anywhere on the surface (the tip is pushed inward slightly).

TactiPad drawing board

The TactiPad can be used to create free-hand drawings or more exact drawings with the help of the tools (ruler, protractor, triangle and compasses). The GraphGrid and CircleFrame accessories extend the range of drawings that can be made even further. These devices can be used by all age groups, starting from the age of 4.

Depending on the age and the purpose of the diagram, it can be more exact for teaching basic concepts, for explaining and teaching math and science or for fun drawing in which preciseness is required. On the other hand, the TactiPad can also be used for a quick sketch.

The TactiPad is specifically useful as a valuable and convenient method of communication between a VIP and a sighted person.

TactileView ClickPad

The ClickPad holds printed audio-tactile diagrams (tactile graphics that contain audio information objects with audio style) and is available in various sizes for different paper sizes. For more information, read the section ‘What is an audio tactile diagram’.

TactileView design – and production software

The software is in the first place aimed towards a sighted user. However, it is fully accessible with a screen reader. All menus and dialogs have short cut keys. The software has functionality to support screen reader users. Extra menus become available in the software when the digital pen is connected.

As mentioned in ‘Introducing the TactileView tactile graphics suite’, using the TactileView digital pen in most cases requires a high level of experience. We strongly suggest to practise the various skills in a certain order to develop the necessary skills before starting to use and combine the products in the TactileView Graphics Suite.

Depending on the amount of support at hand, we recommend to take care of some preconditions to avoid disappointment in using the TactileView digital pen. Make sure all sections in the category ‘Using TactileView with a screen reader’ are mastered as well.

Why drawing with the digital pen on the TactiPad?

Do you wish to digitize the drawing that you create on the TactiPad drawing board? Do you want to share your digital designs with others for further processing? Or do you want to use the objects in TactileView for more accuracy in your drawings?

If you answered ‘yes’ to any of these questions, there are specific advantages to using the digital pen to combine the functionality of both TactileView and the TactiPad. In other cases, the separate use of both products will usually be sufficient.

Keep in mind that the skill level of the combination of products is

Please note, we bring up this question while the effort involved in to creating a digital design is relative high.

Why using a TactileView ClickPad?

By its nature, braille characters have a fixed size that takes up a relatively large amount of space in a tactile graphic. For diagrams in which many (braille) text labels are required, the addition of an audio information layer can help to reduce the amount of space needed for text information. Specific areas in design can be provided with audio labels that provide spoken information. When clicking with the digital pen on the position of the audio style, its content will be pronounced. The audio content can be text (using Text to speech) as well as music or microphone recordings (.mp3 files).

See the section ‘Adding audio style’ to find out how audio styles can be added to the design.

Initial rest state

Initially, the digital pen will be in its ‘rest state’, in which nothing will be drawn in the software when moving or pressing down with the pen. This way, any unintentional ‘pen contact’ (pressing down with the pen tip) will not yet cause any changes in the design. The rest state of the pen is announced by a tinkling sound when pressing down.

In order to change the operation/function of the pen, open the context menu by pressing the pen down anywhere on the surface for 1 second. You will hear a sound of five ascending tones. After the fifth tone, the context menu is opened. Releasing the pen before the last tone was played will not open the context menu. This allows you to cancel before unintentionally opening the menu.

Selecting an option from the context menu

After the context menu has opened, the pen is used to operate the software by cycling through the available options and making a selection. The selected option will be pronounced by the screen reader.

The context menu both contains functions for drawing on the TactiPad, as well as exploring audio tactile diagrams on the ClickPad.

Audio reading system with TactileView digital pen and ClickPad

In the explore mode (Ctrl+E), the audio information in audio-tactile diagrams can be explored. The printed design is placed on the ClickPad and the corresponding digital design is opened in TactileView. By clicking with the pen in the tactile diagram, any audio information that is present at this position is activated.

Explore mode allows you to interact with a TactileView file the way a user will. For example, when you click a text label in a file while using explore mode, the text label will be voiced via text-to-speech instead of becoming selected so that you can edit it like it does in design mode. Similarly, the audio labels for drawing objects will play when the object is clicked, instead of the object becoming selected for editing.

Limited options for changing audio information in the file are available within explore mode, but otherwise files cannot be edited from this mode. If you would like to make changes to anything else in the file, you must switch back to design mode to do so.

You can control some user settings from explore mode, such as selecting a voice or initiating digital pen calibration. For information on calibrating the digital pen or using it with a file in explore mode, please refer to the Connecting and Calibrating the Digital Pen and Using Explore Mode with the Digital Pen tutorials.

Entering explore mode

In order to use a file in explore mode, you must first open it in TactileView, which defaults to design mode when a file is opened. Once you have a file open, explore mode can be activated in one of three ways: by selecting the Explore with Speech and Sound icon from the tool bar across the top of the screen, by selecting the Explore with Speech and Sound option from the View menu or by pressing CTRL+E.

Exploring a file

When you first open a file in explore mode, certain information about the file is automatically voiced. The name of the currently selected speech voice is spoken, as well as the title of the file. TactileView also tells you how many audio styles (audio labels) are in the file when you first enter explore mode.

You can explore the file by clicking different items in the file with the mouse. The digital pen provides an accessible way to explore the file. For more information on using the digital pen with TactileView files in explore mode, please refer to the Using Explore Mode with the Digital Pen tutorial.

When you click on a text label, the text in the label is spoken via text-to-speech. When you click on an object with an audio label, the audio label is played. If the audio label contains both synthesized speech and a sound file, the synthesized speech will begin first and then the sound file will play. Clicking on a blank area or on an object other than a text label that does not have an audio label will cause TactileView to voice “empty.”

Changing an object’s audio label

If you discover an object that does not have an audio label and want to add one, you can right-click it and choose Change Audio Style for Object option from the context menu. This brings up the audio label properties dialog, which allows you to create an audio label the same way you would in design mode. For more information on the options on this dialog, please refer to the Adding and Editing Audio Labels tutorial. When you are done making changes, choose the OK button to close the dialog and apply your audio label.

You can also edit existing audio labels for an object by right-clicking the object and choosing Change Audio Style for Object from the context menu to bring up the audio label properties dialog. Make any desired changes on this dialog, then choose the OK button to close the dialog and apply your changes to the audio label.

Adding a voice memo

Sometimes it can be useful to add an audio label without attaching it to a drawing object. This is especially true when the file you’re working with is a fused bitmap, because nothing in a fused bitmap is selectable. This type of audio label, called a voice memo, is shown in the file and can be clicked to hear the audio information, but it will not be embossed in the drawing when the file is embossed.

To add a voice memo, right-click anywhere in the file and choose the Place Voice Memo option from the context menu. To define your voice memo area as a small circle, click the place in the file where you’d like the voice memo to be. To create a line as the voice memo area, click and drag the mouse to draw the line, then release it. To create a freehand closed shape as the voice memo area, click and drag the mouse to draw the shape, releasing the mouse button close to the starting point of the freehand shape object.

As soon as you have defined the voice memo area, the software will begin recording from the computer’s microphone to create the voice memo content. If you wish to record from the microphone for your voice memo, begin speaking into the microphone immediately and then click anywhere in the file to finish recording. If you would like to create a different type of voice memo, simply click anywhere in the file after defining the voice memo area to quickly end the recording process, then right-click the voice memo area to bring up the standard audio label properties dialog and define your audio label as desired.

Setting the voice for text-to-speech

To choose a different voice for synthesized speech for audio and text labels, right-click anywhere in the file, pick the Select a voice option from the context menu and choose the desired voice from the pull-down list to the right. TactileView will immediately begin using the newly-selected voice for synthesized speech.

Exiting explore mode

When you wish to return to design mode, press ESC on the keyboard or right-click anywhere in the file and choose Quit Explore Mode in the context menu.
