The aim of this study is to investigate how we modulate our grip scaling when inconsistent or no haptic information of target object is provided. Participants put on a head mounted display to independently manipulate each visual and haptic information of the target object. We found that i) participants tended to rely on haptic information dominantly for grip scaling when there was a conflict between visual and haptic information, and that ii) kinematics properties in the condition where the visual image corresponding to the 5-cm object was presented but no real object was presented (i.e., no haptic information was provided) were quite different from those in the condition where the veridical haptic information was provided. These results suggest that, for appropriate grip scaling, vision is not enough to compensate for a lack of (or inconsistent) haptic information. |
