Abstract
An exemplary system and method are disclosed for a handheld or hand-enclosed instrument configured with ultra-wideband localization using unidirectional messaging protocol based on time difference of arrival (TDoA) measurements that can be used as inputs, in a realtime control loop, to a software application that uses the handheld or hand-enclosed instrument as an input user interface. The handheld or hand-enclosed instrument can be readily employed for UI in large work areas (e.g., 2D), such as a whiteboard or wallboard, with sub-millimeter resolution and sub-millisecond latency. The handheld or hand-enclosed instrument can be readily employed in a UI device for non-conforming 3D workspace such as a sculpting instrument, in hand-enclosed game interface, as a remote medical instrument, among others described herein.
