Outline of Final Research Achievements

We investigated the characteristics of tactile recognition by integration of body motion and haptic sensation in a state in which haptic sensation accompanying operation is fed back to the foot rather than the operating hand. We developed a device capable of presenting force (pressure) to 128 points on foot sole, and evaluated weight / stiffness, two-dimensional shape and three-dimensional shape recognition characteristics in case of the alternative presentation. For weight and stiffness, it was proved that the accuracy close to that by hand was obtained. Regarding recognition of two-dimensional shape, it was possible to perform the recognition task at the correct rate and time as in the case of using the same device to hand. In recognition of three-dimensional shape, it became clear that both correct answer ratio and completion time are inferior compared with the case where stimulus presentation with the same degree of freedom is given to the hand.
