In the present study, the coordination between vision and haptics in size perception was examined by magnitude estimation (ME), magnitude production (MP) and cross-modality matching (CMM). The ME and MP data showed that a metric property of vision was characterized as linear, whereas that of haptics was characterized as nonlinear. We found an asymmetry in CMM between sizes perceived visually and by touch. The results indicate that the seen and felt sizes may not be transformed straightforwardly but may be coordinated by subsystems within each modality leading to a motor signal for grasping action and a visual signal for the visual apprehension of the haptic attributes of an occluded object
