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 haptic actuator may include a housing, a stator coupled to a medial interior portion of the housing, and a field member within the housing and having an opening receiving the stator therein. The field member may include a frame, and at least one permanent magnet carried by the frame. The at least one permanent magnet may include side-by-side magnetic segments having alternating magnetic polarizations with at least one non-vertical magnetic polarization transition zone between adjacent magnetic segments.

Abstract: A haptic actuator may include a housing, at least one coil carried by the housing, and a field member having opposing first and second sides. The haptic actuator may also include a respective flexure bearing mounting each of the first and second sides of the field member to be reciprocally movable within the housing responsive to the at least one coil. At least one of the flexure bearings may include an arm and a damper body attached thereto.

Abstract: Examples of the disclosure enclose an optical target on an encoder and sensors inside a single integrated module, wherein the encoder and the sensors are coupled to the same rigid body to maintain optical alignment between the sensors and the optical target on the encoder. Further, the module itself may be hermetically sealed to protect the optical path (e.g., from a light source to the optical target to the sensors) from contamination due to outside dirt, debris, or light sources internal/external to the device that might further interfere with alignment and/or proper sensing. Because the integrated module results in smaller variations in the alignment between the optical target and the sensors, the dynamic range of the sensors may be reduced, resulting in less power consumption and, potentially, longer battery life for the device. The use of an integrated module can also enable relaxed manufacturing requirements for the optical sensor and/or the optical target.
