Outline of Final Research Achievements

Tactile graphics are images that use raised surfaces so that visually impaired people can feel them. In this study, we have developed an algorithm for recognizing hand-drawn figures. We have then conducted a usability evaluation experiment with 13 sighted participants. In this experiment, our software system, which is with an interface of a hand-drawn figure input method, has been compared with the two conventional software systems, Microsoft PowerPoint (PPT) and Edel. Here, Edel is a software system for drawing figures of tactile graphics, and its user interface is similar with that of PPT. As results, there was a significant difference between the average scores of our system and PPT, and also there was a significant difference between the average scores of our system and Edel. Our result suggests that a drawing software system with an interface of a hand-drawn input method is better than conventional drawing software systems with mouse-and-keyboard input methods.
