The TactileView digital pen is combined with the TactiPad or the TactileView ClickPad. The TactiPad is mainly meant to enable the user to make a digital version while drawing a tactile diagram, whereas the TactileView ClickPad is only meant to explore audio-tactile diagrams with speech and sound.
This is how it works
The TactileView digital pen’s receiver is attached to the side of the TactiPad or ClickPad, overseeing the whole drawing surface. The pen transmits a signal, and the receiver receives it when there are no obstacles such as fingers in the way. This means that the receiver needs to have a clear sight of the pen’s tip to work properly.
The transmitter only sends out signals when the tip is pressed. The TactileView software calculates and processes the position of the pen’s moves and clicks. Every function in the TactileView software can be operated using the TactileView digital pen. Using the keyboard is not needed.
