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.
Claims25
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.
A method, comprising:
- providing a vacuum source configured to produce a pressure level in response to an input signal;
- providing a moveable member;
- and
- providing a housing, the 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.
A method, comprising:
- receiving a signal;
- and
- modifying, based on the received signal, a pressure within a volume defined by a cavity between a braking member and a moveable member, wherein a resistive force is applied to the moveable member to provide a haptic effect.
A computer-readable medium storing code representing instructions to cause a processor configured to be operatively coupled to an apparatus to perform a method, the method comprising:
- receiving a signal;
- and
- modifying a pressure within a volume defined by a cavity between a braking member and a moveable member based on the received signal, wherein a resistive force is output to the moveable member by the braking member based on the modifying of the pressure.
