A 3D interface device with force feedback: a virtual work space for pick-and-place tasks

The construction of the virtual work space for pick-and-place tasks with a new 3D interface device named SPIDAR II is discussed. The device can measure the motions of the thumb and the forefinger, and can provide the force sensations to the thumb and the forefinger. The operator can manipulate the virtual objects directly in the virtual work space using the device. The pick-and-place tasks are performed in the virtual space. The effects of the force sensations which are provided by the device are estimated. The results indicate that the appropriate forces are important for the pick-and-place task. The virtual block gives the best performance of pick-and-place tasks in virtual work space
