| 1. A haptic feedback mouse device for providing haptic sensations to a user, said haptic feedback mouse device comprising:
a housing physically contacted by said user and moveable in an x-y plane;
a sensor coupled to said housing and operative to output a sensor signal indicative of said movement in said x-y plane;
an actuator coupled to said housing; and
an eccentric mass coupled to said actuator, wherein said eccentric mass can be rotated by said actuator, and wherein said
rotation of said eccentric mass causes inertial haptic sensations to be output on said housing and felt by said user [ ;
said actuator being controlled harmonically with a drive signal input to rotate said eccentric mass in two directions and
produce an inertial vibration] .
