Abstract: A system and method for conditioning execution of a control function on a determination of whether or not a person's attention is directed toward a predetermined device. The method involves acquiring data concerning the activity of a person who is in the proximity of the device, the data being in the form of one or more temporal samples. One or more of the temporal samples is then analyzed to determine if the person's activity during the time of the analyzed samples indicates that the person's attention is not directed toward the device. The results of the determination are used to ascertain whether or not the control function should be performed.

Abstract: One or more images can be captured with a depth camera having a capture location in a coordinate space. First and second objects in the one or more images can be identified and assigned corresponding first and second object locations in the coordinate space. A relative position can be identified in the coordinate space between the first object location and the second object location when viewed from the capture location by computing an azimuth angle and an altitude angle between the first object location and the object location in relation to the capture location. The relative position includes a dimension of depth with respect to the coordinate space. The dimension of depth is determined from analysis of the one or more images. A state of a computer program is changed based on the relative position.

Abstract: A method for detecting direction conveyed by a user when interfacing with a computer program executed on a computing device. The computing device being interfaced with an image capture device. The method includes detecting a human head of a person in the image taken with the image capture device and assigning the human head a head location. And, detecting an object held by the person in the image and assigning the object an object location. The method determines a relative position in space between the head location and the object location from the capture location, such that the relative position is used to identify a pointing direction of the object.

Abstract: A method for controlling a view of a scene is provided. The method initiates with detecting an initial location of a control object. An initial view of the scene is displayed on a virtual window, the initial view defined by a view-frustum based on a projection of the initial location of the control object through outer edges of the virtual window. Movement of the control object to a new location is detected. An updated view of the scene is displayed on the virtual window, the updated view defined by an updated view-frustum based on a projection of the new location of the control object through the outer edges of the virtual window.

Abstract: One or more images can be captured with a depth camera having a capture location in a coordinate space. First and second objects in the one or more images can be identified and assigned corresponding first and second object locations in the coordinate space. A relative position can be identified in the coordinate space between the first object location and the second object location when viewed from the capture location by computing an azimuth angle and an altitude angle between the first object location and the object location in relation to the capture location. The relative position includes a dimension of depth with respect to the coordinate space. The dimension of depth is determined from analysis of the one or more images. A state of a computer program is changed based on the relative position.

Abstract: Detecting direction pointing direction when interfacing with a computer program is described. Two or more stereo images presented in front of two or more corresponding image capture devices can be captured. Each image capture device having a capture location in a coordinate space. The image capture devices can be synchronized with a strobe signal that is visible to each image capture device. When a person is captured in the image, first and second body parts of the person in the image can be identified and assigned first and second locations in the coordinate space. A relative position that includes a dimension of depth can be identified in coordinate space between the first location and the second location when viewed from the capture location.

Abstract: Real-time simulation of liquids is disclosed. A liquid may be modeled as a collection of particles. Particles separated from one or more nearest neighbor particles by a distance greater than a threshold distance may be separated out as droplets. An iso-surface may then be determined and rendered for the particles not separated out as droplets. The droplets may be rendered as sprites.

Abstract: A method for processing interactive user control with a scene of a video clip is provided. The method initiates with identifying a head of a user that is to interact with the scene of the video clip. Then, the identified head of the user is tracked during display of the video clip, where the tracking enables detection of a change in position of the head of the user. Next, a view-frustum is adjusted in accordance with the change in position of the head of the user. A computer readable media, a computing device and a system for enabling interactive user control for defining a visible volume being displayed are also included.
