| 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.
