視覚障害者用電子レーズライタの試作

抄録

We have developed two prototypes of the electronic tactile drawing system. The first one consists of a PC, a tablet device, a tactile display device and originally programmed software. The evaluation of the system showed its potentialities for a writing and explanation tool of graphics for blind persons. It posed a few technical problems as well. One of them was separation of the input and output devices. This problem was solved in the second prototype by developing a 2-axis arm positioning system. The new system allows users to directly draw on the tactile surface and evaluators favored this feature.
