摘要

A pointing interface for natural human interaction with a display-based computer system includes a hand-manipulated pointer configured to permit it to be aimed by line of sight to point at any arbitrary position within the user's field of view, including positions beyond the user's natural reach, and to be swept along any arbitrary path and at any arbitrary speed within the user's natural capability. A detector detects emanations from at least some positions at which the pointer may be aimed. Circuitry identifies the locations of positions at which the user is aiming the pointer. The interface enables the user to point to a position within his field of view and beyond his reach, move his hand along any arbitrary path and at any arbitrary speed within the user's natural capability to point to another position, and so on, and to have the circuitry automatically identify the locations of the series of positions to which he has pointed.
