Abstract: A user is authenticated based on user features that can be captured by a camera, such as facial features or eye features. In order for the user to be authenticated, an image is captured of the user while the user is within an interaction zone, which is an area that is within both a field of view of the camera and a suitable distance range from the camera. If the user is not within the suitable distance range from the camera, then feedback is provided indicating that the user is not within the suitable distance range from the camera. Various feedback can be provided, such as one or a combination of audio, visual, and haptic feedback. The feedback notifies the user that an adjustment is to be made to the location of the user and/or the camera in order for the user to be within the interaction zone.

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.
