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: A linear haptic actuator may include an actuator housing and at least one coil carried by the actuator housing. The linear haptic actuator may also include field members moveable along a path of travel within the actuator housing in response to the at least one coil and a respective end biasing member between each end field member and adjacent portions of the actuator housing. A respective internal biasing member may be between adjacent field members.
