Abstract: The present disclosure relates to a method of providing at least one image of at least one real object captured by at least one scene camera of a plurality of scene cameras mounted on a vehicle. The method includes: providing camera poses of respective scene cameras of the plurality of scene cameras relative to a reference coordinate system associated with the vehicle, providing user attention data related to a user captured by an information capturing device, providing at least one attention direction relative to the reference coordinate system from the user attention data, determining at least one of the scene cameras among the plurality of scene cameras according to the at least one attention direction and the respective camera pose of the at least one of the scene cameras, and providing at least one image of at least one real object captured by the at least one of the scene cameras.

Abstract: A method for providing position information for controlling at least one function of an environment provided with an environment coordinate system comprises the steps of receiving image information associated with at least one image of at least one part of the environment captured by a camera of a mobile device, the mobile device being separate from the environment, determining a position associated with the mobile device in the environment coordinate system according to the image information associated with the at least one image, and providing position information indicative of the position associated with the mobile device in the environment coordinate system to control at least one function of the environment according to the position. There is also provided a method and system which provides movement information indicative of a movement associated with the mobile device relative to the environment coordinate system to control at least one function of the environment according to the movement.

Abstract: Systems, methods, and computer readable media to improve the operation of detecting contact between a finger or other object and a surface are described. In general, techniques disclosed herein utilize a depth map to identify an object and a surface, and a classifier to determine when the object is touching the surface. Unlike the prior art, a measure of the object's “distance” is made relative to the surface and not the camera(s) thereby providing some measure of invariance with respect to camera pose. The object-surface distance measure can be used to construct an identifier or “feature vector” that, when applied to a classifier, generates an output indicative of whether the object is touching the surface. The classifier may be based on machine learning and can be trained off-line before run-time operations are commenced. In some embodiments, temporal filtering may be used to improve surface detection operations.

Abstract: Systems, methods, and computer readable media to categorize a pixel (or other element) in an image into one of a number of different categories are described. In general, techniques are disclosed for using properties (e.g., statistics) of the regions being categorized to determine the appropriate size of window around a target pixel (element) and, when necessary, the manner in which the window may be changed if the current size is inappropriate. More particularly, adaptive window size selection techniques are disclosed for use when categorizing an image's pixels into one of two categories (e.g., black or white). Statistics of the selected region may be cascaded to determine whether the current evaluation window is acceptable and, if it is not, an appropriate factor by which to change the currently selected window's size.

Abstract: A method for representing virtual information in a view of a real environment is provided that includes: providing a system setup including at least one display device, wherein the system setup is adapted for blending in virtual information on the display device in at least part of the view, determining a position and orientation of a viewing point relative to at least one component of the real environment, providing a geometry model of the real environment, providing at least one item of virtual information and a position of the at least one item of virtual information, determining whether the position of the item of virtual information is inside a 2D or 3D geometrical shape, determining a criterion which is indicative of whether the built-in real object is at least partially visible or non-visible in the view of the real environment, and blending in the at least one item of virtual information on the display device in at least part of the view of the real environment.
