摘要:
Techniques for controlling motions using motion recognizers generated in advance by users are described. According to embodiment, the motion recognizers created by end users are utilized to control virtual objects displayed in a virtual environment. By manipulating one or more motion sensitive devices, end users could command what the objects to do in the virtual environment. Motion signals from each of the motion sensitive devices are recognized in accordance with the motion recognizers created in advance by the users. One or more of the motion signals are at the same time utilized to tune the motion recognizers or create additional motion recognizers. As a result, the motion recognizers are constantly updated to be more accommodating to the user(s).

Techniques for selecting a portion of a 3D virtual environment are disclosed, where the portion of the 3D virtual environment may be one or more objects in the 3D virtual environment or one of scenes in the 3D virtual environment. A motion sensitive device (controller) is used. The controller generates sensor data sufficient to derive position and orientation of the controller in six degrees of freedom. In one embodiment, when selecting the portion of the 3D virtual environment, the controller generates a ray to an interaction of a display screen provided to display the 3D virtual environment, wherein the ray is further projected into the 3D virtual environment by a ray tracing technique as if the user had a real laser pointer that crosses from the physical world into the 3D virtual environment being displayed. Further a user is optionally to use a secondary input device to select one or more points or objects in a 3D space to control a distance along the ray being used.

Techniques for using a motion sensitive device as a controller are disclosed. A motion controller as an input/control device is used to control an existing electronic device (a.k.a., controlled device) previously configured for taking inputs from a pre-defined controlling device. The signals from the input device are in a different form from the pre-defined controlling device. According to one aspect of the present invention, the controlled device was designed to respond to signals from a pre-defined controlling device (e.g., a touch-screen device). The inputs from the motion controller are converted into touch-screen like signals that are then sent to the controlled device or programs being executed in the controlled device to cause the behavior of the controlled device to change or respond thereto, without reconfiguration of the applications running on the controlled device.

Techniques for performing accurate and automatic head pose estimation are disclosed. According to one aspect of the techniques, head pose estimation is integrated with a scale-invariant head tracking method along with facial features detected from a located head in images. Thus the head pose estimation works efficiently even when there are large translational movements resulting from the head motion. Various computation techniques are used to optimize the process of estimation so that the head pose estimation can be applied to control one or more objects in a virtual environment and virtual character gaze control.

Techniques for performing motion recognition using generalized motion recognition capability are disclosed. At least two types of sensors are used to generate sensor signals about a motion made by a user. The sensor signals are then transformed to device-independent motion signals that may be used to build generalized motion recognizers or used with one or more generalized motion recognizers responsive to the sensors. At least one of objects in a virtual interactive environment is responsive to a recognition signal determined from the motion signal and the generalized motion recognizers.

Techniques for motion recognition using multiple data streams are disclosed. Multiple data streams from inertia sensors as well as non-inertial sensors are received to derive a motion recognition signal from motion recognizers. These motion recognizers are originally constructed from a training set of motion signals and may be updated with received multiple sensing signals. In one aspect, multiple data streams are converted to device-independent motion signals that are applied with the motion recognizers to provide a generalized motion recognition capability.

Techniques for non-disruptive embedding of specialized elements are disclosed. In one aspect of the techniques, ontology is defined to specify an application domain. A program interface (API) is also provided for creating raw features by a developer. Thus a module is provided for at least one form of statistical analysis within the ontology. The module is configured automatically in a computing device with the API in response to a system consistent with the ontology, wherein the system has no substantial requirement for specialized knowledge of that form of statistical analysis, and the module has no substantial requirement for specialized knowledge of particular functions provided by the system.
