Abstract: Fiducial patterns that include sub-patterns of dot-like markers are generated or applied on or in transparent glass or plastic material, for example an optical element such as a cover glass or lens attachment. A camera may capture multiple images through the glass or plastic element that include diffraction patterns caused by the fiducial patterns. The diffraction patterns from multiple images may be processed and analyzed to extract information including but not limited to centroids of the sub-patterns of the fiducial patterns. This information may, for example, be used to estimate location of the fiducial 10 patterns with respect to the camera, and thus to estimate pose of the glass or lens element with respect to the camera. Information such as serial numbers and prescriptions can also be encoded in the fiducial patterns and extracted from the respective diffraction patterns.

Abstract: A system may include an electronic device such as a head-mounted device and a handheld input device for controlling the electronic device. The handheld input device may include a stylus and a removable sleeve on the stylus. The input-output capabilities of the handheld input device may be shared between the stylus and the removable sleeve. The stylus may include touch sensor circuitry, a force-sensitive tip, and a motion sensor. The sleeve may include conductors for translating touch input on the sleeve to the touch sensor circuitry on the stylus, a deformable member for translating forces on the sleeve to the force-sensitive tip of the stylus, and visual markers that can be detected by an external camera and used with motion sensor data from the stylus to track the handheld input device. The removable sleeve may include haptic output devices and a battery and may be attached to an item without electronics.
