Abstract: Haptic feedback can be provided to a user via an input device to give a user a richer interaction experience with the input device and host device. The input device can include a magnet and a host device can include an array of coils. The coils can be driven to generate a magnetic field (or one or more magnetic fields) that can exert a force on the input device to provide haptic feedback. In some examples, the haptic feedback can be a push force pushing the input device away from the device or a pull force pulling the input device toward the device. In some examples, the haptic feedback can guide the input device using lateral forces. The haptic feedback described herein can be used for writing, drawing or actuating virtual input controls in a user interface.

Abstract: According to some embodiments, a haptic feedback module for generating a haptic feedback event is described. The haptic feedback module includes an enclosure having walls that define a cavity. The enclosure is capable of carrying operational components within the cavity that include a frame that includes tungsten, a magnetic coil element that is capable of generating a magnetic field, a magnetic element that is carried within an aperture of the frame, linear-actuation end stops that are welded to a first end of the frame and a second end of the frame that opposes the first end, and springs that couple together the walls of the enclosure to the linear-actuation end stops.
