| Outline of Final Research Achievements |
In the present study, we aimed to build a real-time feedback system for the visually impaired persons by constructing a human performance model of the tactile, auditory system. The system is based on the sense of touch and hearing reaction and aimed to support real-time adaptive information to the visually impaired persons. By using NIRS and fMRI, we measured neural responses of the healthy, pseudo-blind healthy, and blind subjects during tracing experiment using the actual stimuli of acrylic material, and the mimic stimuli caused by the touch panel that implements the 2.5-dimensional tactile presentation method by shear force. Then, we quantified and standardized the tactile sensation. Further, based on the present results, we developed a prototype of a real-time feedback system based on the sense of touching.
