Abstract
Input devices having a deformable membrane and methods of their use are disclosed. In one embodiment, an input device includes a body, a deformable membrane coupled to the body such that the body and the deformable membrane define an enclosure filled with a medium, and an internal sensor disposed within the enclosure, the internal sensor having a field of view configured to be directed through the medium and toward a bottom surface of the deformable membrane. The input device further includes a controller configured to receive an output signal from the internal sensor corresponding to a deformation in the deformable membrane, determine a gesture based on the output signal from the internal, and provide a gesture signal corresponding to the gesture.
