Abstract: Learning content may be provided to a user where the learning content may contain learning objectives. A response to the learning content may be received. The response may be analyzed by determining whether the response was the proper response to the learning objectives. If the response was a proper response, less questions on the learning objective may be presented in the future and the if response was an improper response, additional questions on the learning objective may be presented in the future.

Abstract: Face recognition training database generation technique embodiments are presented that generally involve collecting characterizations of a person's face that are captured over time and as the person moves through an environment, to create a training database of facial characterizations for that person. As the facial characterizations are captured over time, they are will represent the person's face as viewed from various angles and distances, different resolutions, and under different environmental conditions (e.g., lighting and haze conditions). Further, over a long period of time where facial characterizations of a person are collected periodically, these characterizations can represent an evolution in the appearance of the person. This produces a rich training resource for use in face recognition systems. In addition, since a person's face recognition training database can be established before it is needed by a face recognition system, once employed, the training will be quicker.

Abstract: Tracking and following technique embodiments are presented that are generally employed to track and follow a person using a mobile robotic device having a color video camera and a depth video camera. A computer associated with the mobile robotic device is used to perform various actions. Namely, in a tracking mode, a face detection method and the output from the color video camera is used to detect potential persons in an environment. In addition, a motion detection method and the output from the depth video camera is also used to detect potential persons in the environment. Detection results obtained using the face and motion detection methods are then fused and used to determine the location of one or more persons in the environment. Then, in a following mode, a mobile robotic device following method is used to follow a person whose location was determined in the tracking mode.

Abstract: The subject disclosure is directed towards detecting symbolic activity within a given environment using a context-dependent grammar. In response to receiving sets of input data corresponding to one or more input modalities, a context-aware interactive system processes a model associated with interpreting the symbolic activity using context data for the given environment. Based on the model, related sets of input data are determined. The context-aware interactive system uses the input data to interpret user intent with respect to the input and thereby, identify one or more commands for a target output mechanism.
