    摘要: A feedback-system for managing the position of a frontal camera provided on a portable multimedia device during video communication. The feedback-system comprises a camera image analyzer coupled to the frontal camera and adapted to detect and analyze the pose of a user facing the frontal camera, an optimal video estimator coupled to the camera image analyzer and adapted to calculate a 6-dimensional error-vector of the current position of the frontal camera with respect to an optimal position of the frontal camera, an intuitive feedback manager coupled to the optimal video estimator and adapted to generate a transformation matrix translating the error-vector into an error message for the image displayed on a screen of the portable multimedia device, the intuitive feedback manager being further coupled to the portable multimedia device which is adapted to use the error message for modifying the image displayed on the screen.

    摘要: Method for switching from a first video source to a second video source, the first video source producing first video content being displayed to a user, and the second video source producing second video content, wherein a changing view of a polyhedron with first and second substantially rectangular surfaces is displayed starting with at least a view of the first surface and changing the direction under which the polyhedron is viewed until only the second surface is displayed; the first video content and the second video content are mapped on the first and second surfaces of the polyhedron, respectively, so that at least the first video content is displayed at least at the beginning of the changing view and the second video content is displayed at least at the end of the changing view.
