OBJECT POSITION DETERMINATION
First Claim
1. An apparatus for supporting human-computer interaction, the apparatus comprising:
- a display, wherein the display defines a plane;
one or more light sources to illuminate objects of a user placed in front of the display;
a camera to capture one or more images of the illuminated objects, wherein the camera is to capture images in an image capture direction that is substantially normal to the plane of the display; and
a position determination module coupled with the camera to determine, based on the captured images, one or more positions of the objects in a three-dimensional (3-D) interaction region defined in front of the display.

Abstract
In embodiments, apparatuses, methods and storage media for human-computer interaction are described. In embodiments, an apparatus may include one or more light sources and a camera. Through capture of images by the camera, the computing device may detect positions of objects of a user, within a three-dimensional (3-D) interaction region within which to track positions of the objects of the user. The apparatus may utilize multiple light sources, which may be disposed at different distances to the display and may illuminate the objects in a direction other than the image capture direction. The apparatus may selectively illuminate individual light sources to facilitate detection of the objects in the direction toward the display. The camera may also capture images in synchronization with the selective illumination. Other embodiments may be described and claimed.

13. A method for supporting human-computer interaction with a computing device comprising a display defining a plane, the method comprising:
-
illuminating, by one or more light sources of the computing device, objects of a user placed in front of the display; capturing, by a camera of the computing device, one or more images of the illuminated objects in an image capture direction that is substantially normal to the display; and determining, by the computing device, based on the captured images, one or more positions of the objects in a three-dimensional (3-D) interaction region defined in front of the display. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. One or more non-transitory computer-readable media including computer-executable instructions configured, in response to execution on a computing device comprising a display that defines a plane, to cause the computing device to support human-computer interaction by causing the computing device to:
-
illuminate, by one or more light sources of the computing device, objects of a user placed in front of the display; capture, by a camera of the computing device, one or more images of the illuminated objects in an image capture direction that is substantially normal to the display; and determine, based on the captured images, one or more positions of the objects in a three-dimensional (3-D) interaction region defined in front of the display. - View Dependent Claims (21, 22)
