Abstract: Aspects of the present disclosure relate to eye tracking systems and methods which track eyes by illuminating the eyes using a light source and detecting the eye illuminations using a sensor. Implementations of the present disclosure may utilize wide angle lighting via a plurality of individual light sources which are each oriented in different orientations. A wide area may be illuminated by the different light sources, and these light sources may be selectively turned on and off based on a current location of a user.

Abstract: Consumer electronic devices have been developed with enormous information processing capabilities, high quality audio and video outputs, large amounts of memory, and may also include wired and/or wireless networking capabilities. Additionally, relatively unsophisticated and inexpensive sensors, such as microphones, video camera, GPS or other position sensors, when coupled with devices having these enhanced capabilities, can be used to detect subtle features about users and their environments. A variety of audio, video, simulation and user interface paradigms have been developed to utilize the enhanced capabilities of these devices. These paradigms can be used separately or together in any combination. One paradigm automatically creating user identities using speaker identification. Another paradigm includes a control button with 3-axis pressure sensitivity for use with game controllers and other input devices.

Abstract: Aspects of the present disclosure relate to eye tracking systems and methods which track eyes by illuminating the eyes using a light source and detecting the eye illuminations using a sensor. Implementations of the present disclosure may utilize a light source with a dynamic lighting position to account for changes in lighting conditions during the tracking which interfere with detection of the eye illuminations, such as reflections in glasses which may obscure a user's eyes.

Abstract: Implementations of the present disclosure may include calibration techniques for systems which include eye tracking devices and display devices. The calibration techniques may involve a calibration process which utilizes a plurality of visible calibration targets that each defines a gaze point for a user. The calibration targets may include both targets output to the display device, as well as gaze points located on the eye tracking device itself. The calibration techniques may also include additional sensors on the eye tracking device to gather additional calibration information, such as a back-facing camera which captures images of the display device from the eye tracking device. Increased information regarding system setup that is useful in calibrating the eye tracking system may be obtained from the calibration process.

Abstract: Methods, devices, and systems are presented for determining a distance to an object using a color camera and special markers mounted on the object that refract or reflect different colors depending on the angle at which they are viewed. Different colors can be refracted or reflected using lenticular lenses or other technologies. The color received by the camera reveals the orientation of the markers. The orientation information can be combined with the perceived angular distance between the markers and the known distance between the markers to determine the actual distance to the object.

Abstract: Systems and methods incorporating an embedded sensor in a control stick to detect the presence of an object, such as a thumb. A presence detect signal may be generated by the additional sensor and auto calibration logic then may automatically remove bias from the control stick in real time when the presence detect signal indicates the control stick is not under the influence of a force external to the controller, and therefore at its neutral mechanical position. In further embodiments, embedded sensors are arrayed across an exterior surface of a control stick as a secondary control stick-based positional input device. In such embodiments, tactile or proximity sensor technology may be applied to either improve precision of first positional information generated by the control stick or to control a coordinate space separate from that controlled by first position information provided by the control stick.

Abstract: An interactive video system includes a processor unit configured to provide output signals to a short throw projector. The output signals cause the short throw projector to project images on a projection area located on or parallel to a floor. The processor can receive input signals from one or more user input devices. The input signals represent a simulated user interaction with the images projected on the projection area. The processor can also alter one or more of the images projected on the projection area in response to the input signals. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: 3-D or other glasses with an illuminated light guide for tracking with a camera are presented. The light guide can be a light guide plate (LGP) or other transparent and/or translucent material that conveys light through its interior. LEDs embedded within the frames illuminate the light guide and optionally can be dimmed or brightened depending on ambient lighting.
