Abstract
Navigating user interfaces on connected displays with conventional remote controls or motion-sensor-based pointers may present issues such as cursor drift, instability from hand tremors, and user fatigue. Described systems and techniques can use a companion computing device (e.g., a smartphone, smart watch, wearable device, etc.) as a six-degrees-of-freedom spatial pointer by fusing sensor data. High-frequency relative motion data from an inertial measurement unit (IMU) can be combined with lower-frequency absolute spatial positioning data from an ultra-wideband (UWB) radio that communicates with a display system. This fusion process may use the UWB data as a periodic reference to correct for cumulative drift from the IMU data, which can result in a more stable and accurately positioned cursor. The architecture may also incorporate features such as velocity-compensated damping to mitigate hand tremors and context-aware mode switching to reduce arm fatigue.
