Abstract: A system may include an electronic device such as a head-mounted device and a handheld controller for controlling the electronic device. The handheld controller may have a housing with an elongated shaft extending between first and second tip portions. The handheld controller may include a touch sensor for gathering touch input, a button, rotating scroll wheel, or other input device for gathering other user input, a force sensor for gathering force input, an inertial measurement unit for gathering motion data, a camera for capturing images of the environment, and/or one or more haptic output devices such as an actuator for providing haptic output. The control circuitry may send control signals to the head-mounted device based on the sensor data and user input (e.g., force input, touch input, motion input, voice input, etc.) gathered with the handheld controller.

Abstract: Display backing components for head-mounted devices (HMDs) are described that reduce eddy currents in magnetic fields generated by a coil. A HMD may include a coil that is used to generate a magnetic field that may be used to track position of other devices with respect to the HMD. Display backing components, used to provide rigidity, are modified with holes or other gaps to interrupt the path of the eddy currents and reduce the interference with the magnetic field, thus improving the power efficiency of the coil and of the HMD. These modifications may be formed by casting, drilling, cutting or otherwise perforating the display backing during manufacture.
