Abstract :
This paper addresses the design of a novel computer keyboard embedding 64 miniature actuators providing a programmable force feedback in response to human strokes. A specific electromechanical actuator is designed using a global methodology. Then, a parallel strategy is set to efficiently control all the actuators simultaneously. Finally, two prototypes are presented: the haptic pad and the haptic keyboard. In addition, a graphic interface allows the user to define his preferable force profile: whether he prefers tough or soft keys, smooth of rough sensation or even a buckling-spring like feeling.
