Abstract:
A near-touch interface is provided that utilizes stereo cameras and a series of targeted structured light tessellations, emanating from the screen as a light source and incident on objects in the field-of-view. After radial distortion from a series of wide-angle lenses is mitigated, a surface-based spatio-temporal stereo algorithm is utilized to estimate initial depth values. Once these values are calculated, a subsequent refinement step may be applied in which light source tessellations are used to flash a structure onto targeted components of the scene, where initial near-interaction disparity values have been calculated. The combination of a spherical stereo algorithm, and smoothing with structured light source tessellations, provides for a very reliable and fast near-field depth engine, and resolves issues that are associated with depth estimates for embedded solutions of this approach.

Claim (Index 1):
A system for determining near touch interaction, comprising:\n a display for displaying one or more elements thereon; a plurality of stereo cameras positioned adjacent to the display, at least one of the plurality of cameras being active in a visible light portion of the spectrum, and at least one of the plurality of cameras being active in a portion of the spectrum other than the visible light spectrum; and a processor for causing the display to flash one or more structured light sequences on a user pointer placed adjacent to the display, determining a depth map in accordance with information acquired by the stereo camera pair, and if desired, employing the one or more structured light sequences to possibly refine the depth map, and determining a location corresponding to one or more of the one or more elements displayed on the display to be selected in accordance with the determined depth map; wherein the at least one of the plurality of cameras that is active in the visible light portion of the spectrum operating when ambient light is determined to be sufficient for visible spectrum viewing, and wherein the at least one of the plurality of cameras that is active in other than the visible light portion of the spectrum operating when ambient light is determined to be insufficient for visible spectrum viewing.
