Ergonomic physical interaction zone cursor mapping

摘要

Users move their hands in a three dimensional (“3D”) physical interaction zone (“PHIZ”) to control a cursor in a user interface (“UI”) shown on a computer-coupled 2D display such as a television or monitor. The PHIZ is shaped, sized, and positioned relative to the user to ergonomically match the user's natural range of motions so that cursor control is intuitive and comfortable over the entire region on the UI that supports cursor interaction. A motion capture system tracks the user's hand so that the user's 3D motions within the PHIZ can be mapped to the 2D UI. Accordingly, when the user moves his or her hands in the PHIZ, the cursor correspondingly moves on the display. Movement in the z direction (i.e., back and forth) in the PHIZ allows for additional interactions to be performed such as pressing, zooming, 3D manipulations, or other forms of input to the UI.

主权项

1. A computer-implemented method for moving a cursor on a two-dimensional (“2D”) display in response to motion of a user's hand, the method comprising the steps of:
capturing locations of the user's hand within a monitored physical interaction zone (“PHIZ”), the PHIZ being ergonomically matched to the user's natural range of motions; tracking the locations within the PHIZ to determine motion of the user's hand; and mapping the tracked hand locations from the PHIZ to the display so that motion of the hand in the PHIZ results in a corresponding motion of the cursor on the display.
