This paper describes the implementation of compact force display for finger tips which presents rigid or elastic body of virtual objects. The system uses the tension of a string as a force generator. Flexibility of a string enables non-restricted motion of a finger. The rigid body is generated by a crutch mechanism, and the elastic body is generated by winding a string by DC motor.
