| Abstract(in English) | Focusing on one of characteristics of grasped object "orientation", we investigate the mechanisms of the human sensorimotor integration and visuomotor transformation in grasping movements. In psychophysical experiments, PCA extracted a component related to object orientation from the data of digit position, force and hand posture, when subjects grasped an equilateral triangle object set in various kinds of orientation. A neural network, which integrated visual information and two kinds of motor information (digit position and force) and acquired internal representation of the grasped object, could compute two kinds of motor information simultaneously from the visual information of the object by solving a simple constrained optimization problem. |
