Abstract: A robot (20) includes a base (203, 204) and a detachable probe (205). The probe (205) includes at least one sensor of a least one type. Propulsion of the probe is provided by an ejection mechanism (204, 302) in the base. When the probe is ejected by the base, the probe captures data using its sensor(s) during its trajectory, according to an observation plan established by the base. The probe is recaptured by the base, probe data is transferred to the base, and the probe (205) is configured for a new observation.

Abstract: A device and method is provided for establishing via a processor a common interacting area. The common interacting area is based on the intersection of field of view of a first user device and a second user device. The processor also establishes a border area inside the common interacting area. Any image appearing within the common interacting area that has any portion of it falling within the border area is modified by the processor. The image itself includes a real component and a computer generated component. A system, user interface and method is provided for.

Abstract: A method and device are described for time aligning a current frame of a current video stream with respect to reference frames of a reference video stream, the current video stream corresponding to at least one part of the reference video stream. The method includes: obtaining at least two reference frames corresponding to at least part of at least some of multiple displayed frames displayed on a display; obtaining current frame from images of said displayed frames captured with a camera by shooting said display; and determining a time alignment of said current frame with respect to said at least two reference frames by correlating said current frame with a time interpolation of said at least two reference frames. The time interpolation being based on correlations between the current frame and respectively each of the at least two reference frames, and on at least one correlation between at least two of the selected reference frames together.

Abstract: A method and device for determining a trajectory of a first camera in a three-dimensional scene, the 3D scene including at least one object of interest, a pose information being associated with the at least one object of interest. The method includes determining a set of points of the 3D scene, the set of points representative of a collision-free space of the 3D scene; and determining the trajectory in the 3D scene, The trajectory having a starting point and an ending point, the trajectory being defined with a plurality of points selected within the set, the plurality of points being selected according to a difference of the pose information defined in an image space between pairs of selected points from the starting point to the ending point, the image space being associated with an image of at least a part of the scene acquired with the first camera.
