A typing lesson system with 3D key-echo

摘要

We developed a keyboard typing lesson system, Uchikomikun-3D. This system uses the stereo headphones for guiding the name and the position of each key with the 3D key-echo voices. Using the 3D key-echo, the position of each key can be explained easily and effectively. Experienced users can imagine the motions of fingers correspond to the words with the 3D key-echo, so they can easily obtain the skill of touch-typing. All the guides necessary for the lessons are given with the audio output, so the system is especially effective for visually impaired users.
