(Study Case) Support people in need by welfare technology now
The major aim of our laboratory is to cover and assist sensory function and motor function that disabled persons and elderly persons have lost using some kind of engineering systems. For example, we are working on problem resolution with various approaches developing a system to support walk rehabilitation after stroke, a system that displays neighboring environmental information to visually impaired persons and guide them to their destination and a method to support communication of deaf-blind people and people with arm paralysis. For research and development in the field of assistive technology, in particular, it is important to consider concrete needs of disabled persons and elderly persons, and design a device in accord with each of their characteristics. We aim at realizing practical use of the devices cooperating with enterprises through on-site evaluation in medical care and welfare facilities, and contributing the society with our research results.

(Degeiko Package)Psychophsiological experimental method / Visualize a scale in your head to stimulus measuring
Students perform psychophysical experiments to examine the relationship between the physical quantity when a stimulus such as sound, light or touch is provided and the mental quantity of size and strength that our senses perceive. The threshold and perception of stimuli vary among individuals. If the scale in your head is determined and visualized, the differences can be compared objectively. Through conducting experiments with different physical quantities of stimuli, students will learn the method for digitalizing and graphically recording the mental reaction of subjects. In assistive technology, the interface between people and machine is particularly important. Digitalizing mental quantities enables reflecting human perception and its characteristics in assistive device design.
