Abstract: A method includes running a computer simulation that is controlled at least in part by a handheld controller, displaying images generated by the computer simulation on a display, and projecting at least one image generated by the computer simulation from an image projector coupled to the handheld controller. A system includes a display, a handheld controller, an image projector coupled to the handheld controller, and a processor based apparatus. Another system includes a display, a handheld controller, an image projector that is housed in a unit configured to be releasably docked to the handheld controller, and a processor based apparatus. Storage mediums storing one or more computer programs are also provided.

Abstract: A system, including: a computing device that executes an interactive application and generates and transmits image frames; a head-mounted display (HMD) that receives and presents the image frames, wherein the HMD includes a magnetic emitter that emits a magnetic signal having a synchronization encoding synchronized to the received image frames; a controller device that includes a magnetic sensor that detects the magnetic signal, wherein the controller device processes the detected magnetic signal to determine magnetic position data and read the synchronization encoding, wherein the controller device uses the synchronization encoding to generate corresponding timing data indicating a timing of the magnetic position data based on the synchronization encoding, wherein the controller device transmits the magnetic position data and the corresponding timing data to the computing device; wherein the computing device uses the magnetic position data and the corresponding timing data to determine the location and/or orientation of the controller device.

Abstract: To derive three dimensional (3D) position and orientation of a 3-axis (or more) magnetometer/accelerometer device (such as may be implemented in VR or AR headset or computer game controller) without line of sight constraints, a spinning magnetic field is used to discriminate and remove the external (Earth's) magnetic field from the spinning magnetic field. This reduces the problem to finding the distance to the source of the magnetic field using a calibration table (or formula), finding two angles describing the deviation of the magnetic sensor from the axis of rotation of the spinning magnetic field and the phase around this axis, and from these values deriving the orientation of the sensor.
