FEEDBACK DEVICE FOR TACTILE IMPRESSION OF THREE-DIMENSIONAL GRAPHIC

摘要

PURPOSE:To improve the operability of a 3-dimensional graphic by feeding the tactile impression of an object back to an operator's hands when the operator holds the object on a display screen via an operating means. CONSTITUTION:A main body part 15 is made of a shape memory alloy and attached to the hand of an operator. A tactile impression feedback control part 14 is driven based on the hardness data obtained when an operating means 101 holds an object and drives the part 15 so as to turn it into the shape memory alloy. At this time, the part 14 supplies a control signal to the part 15 in response to the hardness data on the object and therefore the shape memory alloy is deformed to apply a reaction to the hand of an operator. Thus the tactile impression is directly fed back to the hand of the operator when the contact is secured to the object. Then the operability of a 3-dimensional graphic is improved.
