Abstract
In this paper, usability evaluation of a compact Braille reading sensor was carried out. Several sensors with different grips and guide components were fabricated. Using these sensors, sensory evaluation related to usability was conducted. At the same time, self- straitening characteristics of the sensors were evaluated by motion analysis. From the results, it was found that guide part with the groove width spreading toward the front of the sensor is effective for a usable sensor with high self-straightening characteristics, and it was suggested that the grip part should be designed to suit the preference of the user.
