A recently granted patent (Publication Number: US11886650B2) discloses a tracking system that includes a stylus with multiple light emitters of varying sizes and wavelengths, allowing for precise position and orientation detection. The system also comprises a head-mounted device with an optical sensor and processor to determine the stylus's position and orientation based on the emitted light. The stylus can emit different spatial patterns and dots for rotation detection, while the head-mounted device can display virtual objects corresponding to the stylus's position.

Furthermore, the patent describes an electronic system with a stylus featuring light emitters of varying wavelengths arranged around its circumference. The system includes a head-mounted device with a display and camera to detect the stylus's angular position in three-dimensional space. The stylus can provide input by contacting surfaces, and the head-mounted device's processor processes camera images to determine the light emitters' positions for generating corresponding images on the display. The stylus is battery-powered and freely movable for user manipulation, enhancing its usability in various applications.
