Outline of Final Research Achievements

This study aimed at conveying symbolic information to human via only haptic modalities based on the “write to read” approach where the users’ hand and fingers were guided along the letter trajectories by external force applied by the mechanical device that we fabricated. As a result, users were able to identify the lower-case alphabets presented by a fabricated desktop system at an accuracy rate of more than 90% without any prior long-time trainings. We also implemented its hand-held version supposed to be used in practical situations, which successfully conveyed the letter trajectories to untrained users. We demonstrated that this method is superior to the conventional ones in the context of intuitiveness.
