[Pointing response in normal subjects]

Eye-hand open-loop pointing responses were examined in five normal subjects, with visual cues for relative target localization. Pointing errors differed significantly with the position of the target. In some cases, pointing responses in the dark were significantly different from those in the light. Pointing shifts were also significant between the responses immediately after putting the experimental device on and those 15 minutes after. From these results, it was speculated that visual localization and eye-hand coordination may be influenced by the visual context and the passage of time.
