A system is disclosed for media content search and retrieval, and a virtual television channel capable of using that system. The present system may be implemented on a computing device, such as for example a media service server, and a client device, such as for example a set top box for a television system, a mobile telephone, a personal digital assistant or a gaming console. A first aspect of the present system relates to a media download control engine which enables a client device with limited capabilities to play media content which comes from a website in a format not supported by the client device. A second aspect of the present system may make use of the media download control engine to obtain media content and create customized virtual channels. The second aspect in particular relates to a virtual channel engine that schedules a continuous stream of content for the user, which content is selected based on topics of interest to the user.

The present invention is embodied in a system and method for automatically estimating the orientation or pose of an object, such as a human head, from any viewpoint and includes training and pose estimation modules. The training module uses known head poses for generating observations of the different types of head poses and the pose estimation module receives actual head poses of a subject and uses the training observations to estimate the actual head pose. Namely, the training module receives training data and extracts unique features of the data, projects the features onto corresponding points of a model and determines a probability density function estimation for each model point to produce a trained model. The pose estimation module receives the trained model and an input object and extracts unique input features of the input object, projects the input features onto points of the trained model and determines an orientation of the input object that most likely generates the features extracted from input object.

A vision-based gesture interface system, which employs an arbitrary quadrangle-shaped panel and a pointer tip like a fingertip as an intuitive input device. Taking advantage of the panel, the system can fulfill many tasks such as controlling a remote and large display, and simulating a physical keyboard. Users can naturally use their fingers and other pointer tips to issue commands and type texts. The system is facilitated by accurately and reliably tracking the panel and the pointer tip and detecting clicking and dragging actions.
