PURPOSE : The purpose of this study is to examine the effects of eye-hand coordination by visual field interception and the difference of capability in subject attendance on certain kinds of that. The eye-hand coordination is capability that eyesight makes adjust with body exercise or a part of body. METHODS : The object was 40 university students (20 men and 20 women), it was examined using Dynavision2000 and pegboard by assume the 5 situation of visual field interception. ① Dynavision2000 : It was established the mode B and the LED windows is adjust to eye height of object, the legs is stretch out by shoulder width, the hands is raise and make ready to press the button, the distances of between LED windows and object is set the 30cm. ② Grooved pag board (Model 32025) : The pins put in and pull out between each difference groove into 25 holes (5 across and 5 vertical) in order using one hand and the time measured using stop watch.
RESULTS : When dynavision and pag board were used to compare the difference between normal hand-eye coordination and delayed hand-eye coordination in vision impairment, there were significant differences between hand-eye coordination in normal condition (no vision impairment) and hand-eye coordination in all conditions of vision impairment unilateral optic nerve impairment (superior eye, inferior eye), bitemporal hemianopsia, and homonymous hemianopsia.
CONCLUSION : When the samples were calculated by t-test, all of the samples were significantly different from normal and proved that each type of vision impairment affects hand-eye coordination.
