Abstract
It is difficult to fit technical aids, because it depends on engineers' skill and feeling or subjective appeals from disabled people. In this study, we tried to evaluate stress based on 5 physiological indexes. We measured the indexes when normal subjects pointed at targets on the screen with a head-pointer. The results of the evaluation experiments look like the best index is the interval coefficient variable. We have to find out practical way to evaluate stress and experiment on disabled people.
