Haptic feedback system and method
First Claim
Patent Images
1. A system for providing haptic feedback regarding movement of a first member relative to a corresponding second member, comprising:
- a first magnetic field generator associated with one of said first member and said second member;
a first magnetic field coupler associated with the other of said first member and said second member; and
a touch sensor associated with said first member;
wherein said first magnetic field generator establishes a first magnetic field proximate said first magnetic field generator;
wherein said first magnetic field variably couples to said first magnetic field coupler as a function of the position of said first magnetic field generator relative to the position of said first magnetic field coupler;
wherein said first magnetic field tends to maintain said first magnetic field coupler in at least a first predetermined relationship with respect to said first magnetic field generator; and
wherein the operation of said touch sensor is not dependent on said first magnetic field.

Abstract
A haptic feedback system includes movable and static portions coupled by one or more magnetic fields that serve to retard movement of the movable portion with respect to the static portion so as to provide haptic feedback when the movable portion is moved relative to the static portion. A magnet associated with one of the movable and static portions reacts with structure associated with the other of the movable and static portions so as to provide haptic feedback when the movable portion is moved with respect to the static portion.
