| Outline of Final Research Achievements |
In order to realize walking navigation by tactile stimulation of the sole, we developed an insole-type device and conducted a user evaluation experiment for visually impaired people. First, we examined the sensitivity of the foot to stimulation. We found that the device could sense a 0.5mm-thick, 10mm-sided square step while wearing socks. We also implemented a walking navigation system by reading the coordinate data of the road surface and controlling the tactile presentation device in conjunction with a smartphone application. From user evaluation experiments, we found that vibration stimulation to the sole of the foot was not necessarily suitable for presenting information depending on the user's age and posture, so we tried to improve the accuracy of perception by selecting devices and electrical stimulation.

本研究課題は，足裏に装着した触覚提示デバイスが使用者に情報を伝えることで，使用者の安全な移動を提供する「スマートインソール」の実現を目的とする．現在，スマホ画面を注視することによる危険性が社会的問題化している．本システムは，GPSやRFIDタグ等の位置・環境情報および加速度，高度等の携帯端末内蔵センサデータを収集し，目的に応じて使用者に提示する情報を生成する．その情報は触覚，痛覚等の皮膚感覚を利用して使用者へ伝達し，安全な移動を促す．本研究は，環境への実装が進むRFIDタグを活用しつつ，視覚・聴覚障害者への情報提示にも応用できるもので誰もが「幸せ」に暮らせる「安全な福祉社会」の実現を目指す．
