Abstract

A method of human-computer interfacing provides efficient intuitive controls in a three-dimensional space. The method provides a three-dimensional space, characterized by a z dimension approximately parallel to the user's direction of view, and x and y dimensions approximately orthogonal thereto. A control has x and y coordinate sets, and a z coordinate set that spans a range of values. The range can be infinite, making the control accessible at all depths, or can be a finite range, making the control accessible from that range of depths. Movement of a cursor into the control's region initiates user interaction according to the control. The control depth reduces the precision of depth perception required to find the control. Once the user is in the control region, the effective depth for interaction can be relative to the depth when the user entered, providing control interaction independent of entering depth.
