The TactileView digital pen is a special version of a ballpoint pen. The pen writes in ink like a normal pen, but at the same time determines the position of its tip on the drawing surface. In the pen’s tip is a small transmitter, which sends a signal to a receiver. Upon moving or clicking in the drawing surface with the pen, the receiver transmits this position to the TactileView software, just like with a regular computer mouse. Visual impaired people can operate the TactileView software using the TactiPad or TactileView ClickPad.
The pen functions as a drawing tool and transmits to the computer what has been drawn, or as a cursor by transmitting on which location has been clicked. This way, the digital pen enables the user to make a digital version of a tactile diagram or to explore a tactile diagram with speech and sound.
