A Hand-held Display Presenting Visual and Force Information

A hand-held display presenting visual and force information is proposed. The display is constructed with an LCD panel and a moving weight. The forces applied to user's both hands holding the display are changed with the movement of the weight set on the backside of the display. The weight is moved by a PC-controlled servo-motor. With the prototyped display, the force perception affected by the weight movement was psychophysically measured as a fundamental property. The users feel the force changes to the hands, sufficiently
