First Claim
Patent Images
1. An apparatus, comprising:
- a vacuum source configured to produce a pressure level in response to an input signal;
a movable member; and
a housing defining a cavity and coupled to the vacuum source, the housing being configured to output a haptic feedback by engaging the moveable member, the haptic feedback being associated with the pressure level, the pressure level being associated with a volume defined by the cavity and the moveable member.

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.
