✦ Synopsis
To obtain basic data for designing finger Braille communications, the conditions of optimizing vibration stimulus on the back of a finger (finger back) have been investigated. The acceleration of vibration stimulating the finger back is more carefully examined, since this part is sensitive to the acceleration. The effect of a static weight on the finger back, which has been little known, is also investigated. The experimental results show that the acceleration of vibration of 120 Hz is most sensitive to a finger back, and that a static weight between 100 and 200 gf/cm 2 (depending on the direction of vibrations) is sensitive to the same position. The time factors of the stimulation, and the most sensitive position on a finger are also investigated.
