Abstract
A method and apparatus is described for applying haptic feedback using a vacuum source. A housing includes a cavity. The cavity can be positioned near a moveable member such that the cavity of the housing and the moveable member define a volume. The volume has an associated internal pressure. The internal pressure within the volume can be modified based on a received signal such that a resistive force is applied to the moveable member as the pressure is modified.
