Determination of presence data by devices

Abstract:

Multiple sensors are used to determine proximity of a user with respect to one or more media devices. Different types of sensors may determine different types of information regarding user proximity, such as presence or absence, proximity, distance, orientation, movement, identity, or a number of users that are detected. The information, sensor types, and times at which the information is acquired are used to generate data that associates specific devices, sensor types, information regarding user proximity, and the times at which the information is acquired. Instructions may be provided to various devices to cause performance of actions based on the generated data.
