Abstract: A method comprises: capturing images of a movable object in a scene and tracking movement of the object in the scene based on the images, to produce movement parameters that define the movement; generating for display an extended reality (XR) visualization of the physical object in the scene and changing the XR visualization responsive to changing ones of the movement parameters, such that the XR visualization visually reflects the tracked movement; displaying the XR visualization; and converting the movement parameters to control messages configured to control one or more of sound and light, and transmitting the control messages.

Abstract: Systems and methods are described that calculate the interestingness of a set of one or more records in a database, either absolutely (i.e., compared to an overall collection of records) or relative to some other set of records. In one embodiment, the measure is a relative entropy value that has been normalized. Various applications of the measure are described in the context of an information retrieval system. These applications include, for example, guiding query interpretation, guiding view selection and summarization, intelligent ranges, event detection, concept triggers and interpreting user actions, hierarchy discovery, and adaptive data mining.
