Abstract: The present invention provides a method of human-computer interfacing that provides efficient implementation of intuitive controls in a three-dimensional space. The method comprises providing a three-dimensional space, characterized by x and y dimensions, together defining a plane approximately orthogonal to the user's direction of view into the space. A z dimension, approximately parallel to the direction of view, further characterizes the three-dimensional space. Objects in the space can be defined by x, y, and z coordinate sets. A control is provided having x and y coordinate sets as any other object. The z coordinate set of the control, however, spans a range of values, giving the control an increased depth. The control's range of z can be infinite, making the control accessible at all depths, or can be a finite range, making the control accessible only from that range of depths. Movement of a cursor into the region corresponding to the control initiates interaction with the user according to the control.

Abstract: A method and system for tracking attitude of a device includes fixing a two-dimensional array of photosensors to the device and using the array to form a reference frame and a sample frame of images. The fields of view of the sample and reference frames largely overlap, so that there are common imaged features from frame to frame. Sample frames are correlated with the reference frame to detect differences in location of the common features. Based upon detection of correlations of features, an attitudinal signal indicative of pitch, yaw, and/or roll is generated. In the preferred embodiment, the attitudinal signal is used to manipulate a screen cursor of a display system, such as a remote interactive video system (RIVS). However, attitudinal tracking using the invention may be employed in other applications.
