| Outline of Final Research Achievements |
It is difficult for visually impaired individuals to write characters using a pen. This is not only because their visual impairment prevents them from seeing the location of the pen-tip, but also because they are unable to confirm the movement of the pen-tip and their handwriting. In this research, we consider an acoustic digital pen for the visually impaired individuals that will allow them to recognize the movement of the pen by sound. Signals of proper positioning of the proposed pen are provided by the simulated sound's tone colors based on the pen-tip locations. They are produced by the MIDI sound generator in PC. The simulated sound is supposed to be heard with the bone conduction headphones. By enabling to hand-write while checking the direction of the pen movement with the tone color, a visually impaired individual can be expected to write readable characters easily in a shorter time, depending on the training if it is a simple character.
