Embodied object recognition: Biomechanical constraints of hand rotation affect facilitation of the view matching process
T Sasaoka, N Asakura, T Inui
Recent studies have demonstrated that active exploration of 3D object views facilitates subsequent object recognition (Sasaoka et al, 2010 Perception 39 289-308). This facilitation was evident in the generalisation of views in the direction of rotation of a right-hand screw and under a condition where object rotation and hand rotation were compatible. We hypothesised that the ease of hand rotation affects object recognition. We addressed this issue by examining whether the ease of hand rotation facilitated view generalisation performance after active exploration of 3D object views. One group of participants (active group) explored 3D object views by using their right hands to rotate a handle attached to the side of a display. The other group (passive group) passively watched a replay of the active exploration of one participant from the active group. We confirmed a facilitative effect on the view-matching process specifically in the active group. For most participants, this facilitation was observed for the direction that was easiest for rotation of the hand. Our findings suggest that the object recognition process, which is thought to be based on visual information, is also affected by the biomechanical constraints of hand rotation.
