Abstract: Detecting a touch includes receiving image data of a touching object of a user selecting selectable objects of a target surface, determining a rate of movement of the touching object, in response to determining that the rate of movement satisfies a predetermined threshold, modifying a touch detection parameter for detecting a touch event between the touching object and the target surface, and detecting one or more additional touch events using the modified touch detection parameter.

Abstract: Generating a 3D model may include determining, based on sensor data from a touch sensor on a first device, a touch event, wherein the touch event comprises a touch on the first device by a touching object. Generating a 3D model may also include, in response to a touch event, obtaining a first image of the touching object by a first camera of the first device, and obtaining, from a second device, a second image of the touching object, wherein the first image of the touching object captures a first view of the touching object, and wherein the second image of the touching object captures a second view of the touching object. A model of the touching object is generated based on the first image and the second image.

Abstract: Touch detection includes obtaining image data for a finger and a target surface, and determining a touch region in the image data on which the fingertip makes contact with the target surface. A pointing direction of the finger in the image data is determined, and a target region is estimated on the target surface based on the touch region and the pointing direction, wherein the touch region comprises a portion of the target surface that extends from the touch region in a direction of the pointing direction.

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.
