Abstract: A controller configured to control a pointer in a virtual reality environment includes a multi-axis magnetic field sensor, a multi-axis accelerometer, a gyroscope, a touchpad, and a wireless communications circuit. The controller can also include a processor and a memory storing instructions that when executed by the processor, cause the processor to obtain geomagnetic field data from the multi-axis magnetic field sensor, obtain acceleration data describing a direction and a magnitude of force affecting the controller from the multi-axis accelerometer, and obtain angular velocity data describing a rotational position of the controller from the gyroscope. The processor can communicate movement data to a computing device configured to generate a rendering of the virtual reality environment, the movement data describing an orientation of the controller wherein the movement data is based on at least one of the geomagnetic field data, the acceleration data, or the angular velocity data.

Abstract: A headset for experiencing an augmented and/or a virtual reality environment may include a housing defining an interior cavity, with optical components received in the interior cavity of the housing. A front face may be rotatably coupled to a front portion of the housing to selectively enclose the interior of the housing. A computing device including a display may be received in a slot defined between the front portion of the housing and the front face. A face pad may be removably coupled to the housing, opposite the front face, so as to enclose the optical components in the housing. A user may view an augmented/virtual reality environment displayed on the display through the optical components received in the housing. An adjustable head strap assembly may adjustably position the headset on the head of the user.

Abstract: Eye tracking methods and systems for virtual reality (VR) environments are disclosed herein. An example method includes receiving light through a lens positioned in an opening defined through a surface of a head-mounted display (HMD), reflecting an infrared light portion of the light off a display device of the HMD, the display device oriented generally parallel to the lens, and performing eye tracking based on the reflected infrared portion of the light.
