Abstract

In modern society, with the increasing use of such compact devices as smart phones and computers, finger and hand mobility is very important for daily living. Generally, in the case where there is impaired motor function of the hands or fingers, rehabilitation involves boring repetitive exercises. In this study, serious games were implemented using a dynamometer which made it possible to measure grip width and finger grip strength according to the size of the hand. The game was developed based on rhythm games, and, by selectively training the fingers that need rehabilitation, it is possible to improve a variety of functions such as finger agility, power and endurance. In addition, by analyzing data changes during the training process, the intensity of the rehabilitation can be quantitatively assessed. Furthermore, it provided users with an active and fun rehabilitation environment because they could choose and use their own desired music files during their rehabilitation.

Abstract

This study proposed an gaze tracking system which detects the pupil and the center point of the glints from near-infrared camera images and, in order to use this system, implemented visual perception training contents and augmentative and alternative communication software. The center of the pupil and the center of two glint points of the eye images used for gaze tracking were extracted by using a model with four kinds of simple features. After using the calculated distance between the two centers to locate the relative position of the eye-gaze on the monitor, the x and y coordinates of the screen were mapped to match the gaze and the mouse pointer. The visual perception training contents for using the developed gaze tracking system consists of such components as visual acuity, eye movement speed, visual reaction rate, and visual concentration. Furthermore, software was implemented to enable an alternative means of communication to be used by symbols which convey the meaning of vocabulary being used in spoken language.
