Abstract

Liquid Interface is an organic user interface that utilizes ferrofluid as an output display and input button embodiment. Using a matrix of Hall effect sensors, magnetic fields generated by rare-earth magnets worn on the fingertips are measured and are then converted into signals that provide input capability. This input actuates an array of electromagnets. Both Hall effect sensors and electromagnets are contained beneath the surface of the ferrofluid. By matching like polarities between the electromagnets and the rare-earth magnets, haptic force feedback by means of magnetic field repulsion can be achieved.
