“Unident” is a grasping-type force display that can change its inertia by moving a weight in a single axis direction at high speed. By rapidly changing the inertia while the user is shaking the device, we propose a method to simulate the sensation of an impact force being applied, even though no force is actually generated.
Assume the normal perception of impact force as follows:
- a. One first applies a force to the grasping object (e.g., the stick) to shake it.
- b. Then, one perceives an impact due to the instantaneous change in motion caused by an external impact force (e.g., the ball hitting the stick).
On the other hand, our proposed mechanism of pseudo-impact sensation mechanism:
- c. While the grasping object (Unident) is being shaken, the inertia is rapidly changed to simulate an instantaneous change in motion, making one feels as if an impact force were applied to the grasping object.
