A hand-held device that displays visual and force information has been developed. The display consists of an LCD panel and a moveable weight located at the back of the device. While the device is held, the force applied by the user's hands controls the weight's movement. The weight is moved by a PC-controlled servo-motor. Perceptual properties of a prototype display were investigated using force information and visual/force information. Force perception affected by the weight movement was psychophysically measured as a fundamental property. In an experiment, users sufficiently perceived force changes affected by the hands and caused by the weight's movement. Perceptual properties of the presented visual and force information were also discussed.
