  • Publication number: 20200249761
    Abstract: A device for implementing a button click sensation on a touch surface without visually, audibly, or tactilely apparent motion of the surface is disclosed. The device includes a touch surface, a lateral vibration actuator configured to produce lateral vibrations of the touch surface, a friction controller configured to modulate a friction force between the touch surface and one or more appendages, and a touch sensing device configured to measure a location of a plurality of appendages on the touch surface. The device includes a control device configured to synchronize the friction force between the touch surface and at least one appendage of the plurality of appendages to the lateral vibrations produced by the lateral vibration actuator. The control device also applies a lateral force to the at least one appendage to emulate the sensation of a button click when the at least one appendage applies a pressing force to the touch surface that exceeds a threshold level.
