Abstract
Objectives:
The several studies showed that the visual impression dominates tactile impression (e.g. Rock & Victor, 1964) when people manipulate a object. On the other hand, some studies asserted that vision is not always dominant. The several factors affect the interaction between vision and touch (Welch & Warren, 1980). We think the way of touch is one of the important factors for the interaction between vision and touch. In this study, we analyzed the extent that vision adjusted touch and compared the ways of touch, “grasp� and “trace�.
Method:
Fourteen participants estimated the size of squares that they grasped or traced in their fingers and simultaneously viewed thorough the equipment that reduced the squares’ visual size. They selected a match either visually or haptically from a set of comparison squares.
Results:
Participants judged smaller than veridical size when they looked and felt. So it showed that vision affected haptic size judgement. The judged size when they grasped the square was smaller than the judged size when they traced the square.
Conclusions:
The results indicated that the way of touch affected the relationship between vision and touch and was important factor for interaction vision and touch.
