Method and system for recognition of user gesture interaction with passive surface video displays
First Claim
1. A system for use with a processor-generated display presented on a display device in a display area, the system recognizing at least one user-object interaction with a region on a surface of said display device, a hover region defined in three-dimensional space spaced-apart from said surface of said display device, and a virtual scroll region defined in three-dimensional space adjacent a peripheral region of said display area, the system including:
- a first time-of-flight (TOF) system disposed to emit optical energy in a first field of view (FOV) defined generally toward said surface of said display device and to acquire at least a fraction of the emitted said optical energy that is reflected-back by a passive user-object within said first FOV, and to process at least one of z-depth data and A-brightness data within reflected-back said optical energy to discern a probable location in three-dimensional space of said at least one passive user-object interaction;
a second system associated with a second field of view (FOV) defined generally toward said surface of said display device, said second system including at least one of a second TOF system, at least one two-dimensional camera, and at least one mirror, wherein said first TOF system and said second system detect at least a passive user-object interaction in a location;
a system processor coupled to said first TOF system and to said second system to discern from at least one of processed z-depth data and processed A-brightness data acquired by the first TOF system and the second system the location in three-dimensional space of said at least one user-object, said location being any of (1) a portion of said surface of said display device touched by said user-object, (2) a location in said hover region, and (3) a location in a virtual scroll region, an output of said system processor coupleable to said processor-generated display to affect operation of said display on said display device.

Abstract
A system recognizes user-object gesture interactions with the surface of a monitor display, with hover space defined spaced-apart from the display surface, or in virtual scroll regions defined on the periphery of the monitor display. The system recognizes user-object interactions, e.g., gestures, and can affect what is displayed commensurately. The system includes at least a first time-of-flight (TOF) system and at least one of a second TOF, a two-dimensional camera, and a mirror, each TOF system processing at least one of z-depth data and A-brightness data. User-object interactions, e.g., touching(s) of the display surface, location(s) in a hover region, or location(s) in a virtual scroll region, are recognized passively in that the user-object need not have capacitance, resistance, exert force, or deform during gesture interaction. The system may be attached retroactively to the monitor, which may be a large (>22 cm) monitor, or a small cell phone sized monitor.

14. A method, for use with a processor-generated display presented in a display area of a display device, to recognize at least one user-object interaction with at least one of region on a surface of said display device, a hover region defined in three-dimensional space spaced-apart from said surface of said display device, and a virtual scroll region defined in three-dimensional space adjacent a peripheral region of said display area, the method including the following steps:
-
(a) disposing a first time-of-flight (TOF) system so as to emit optical energy in a first field of view (FOV) defined generally toward said surface of said display device and to acquire at least a fraction of the emitted said optical energy that is reflected-back by a user-object within said first FOV, and to process at least one of z-depth data and A-brightness data within reflected-back said optical energy to discern a probable location in three-dimensional space of said at least one user-object interaction; (b) disposing a second system associated with a second field of view (FOV) defined generally toward said surface of said display device, said second system including at least one of a second TOF system, at least one two-dimensional camera, and at least one mirror; and (c) discerning from at least one of processed z-depth data and processed A-brightness data from said first TOF system an actual location in three-dimensional space of said at least one user-object, said location being any of (1) a portion of said surface of said display touched by said user-object, (2) a location in said hover region, and (3) a location in said virtual scroll region, an output of said system processor coupleable to said processor-generated display to affect operation of said display on said display device. - View Dependent Claims (15, 16, 17, 18, 19, 20)
