This patent covers an ultra-wideband localization system designed to enable sub-millimeter precision tracking for handheld devices across large surfaces. The Hardware technology targets applications including whiteboard interfaces, medical instruments, sculpting tools, and gaming controllers.
The Hardware patent tackles the challenge of achieving extremely precise position tracking across large work areas without relying on expensive touchscreen infrastructure. The system combines ultra-wideband radio messaging with multiple sensor inputs, fusing orientation data, contact detection, and position information to reach sub-millimeter accuracy. By adjusting for delays in connections with different cable lengths and signal attenuation patterns, the technology distinguishes between direct signals and multipath reflections that could otherwise compromise accuracy. The approach interpolates peaks in radio frequency pulses to extract high-resolution timing measurements, enabling precise localization across surfaces far larger than what traditional touch-sensitive screens can economically support.
