Outline of Final Research Achievements

This reseach aimed to develop proper walking support based on the acquired walking characteristics of people with low vision. The results indicate visual impairment such as low vision and narrowing of visual field affects the walking motion. Next, the characteristics of stepping over obstacles of participants with corrected eyesight and participants with retinitis pigmentosa. The results suggest participants with retinitis pigmentosa requires more temporal and spatial leeway during obstacle step-over. Lastly, the influences of information acquisition to obstacle step-over motion were investigated. As a result, it was suggested that integrating visual information with tactile information and obtaining detailed images of the height and shapes of obstacles could improve the accuracy and consistency in leg raising during obstacle step-over motion among low vision people.
