An apparatus for generating post-engagement metadata, the apparatus comprising: a network interface configured to be connected to a content provider via a network ; at least one sensor configured to record sensor data at a first location; a user interface manager configured to receive user input from a first user; a memory ; and a processor configured to execute instructions stored in memory, wherein execution of the instructions by the processor is configured to: detect that the first user has terminated engagement with the apparatus; record a last engagement activity before first user is detected as having terminated engagement with the apparatus; determine that the first user has performed post-engagement actions at the first location based on the sensor data from the at least one sensor recorded after the first user terminates engagement with the apparatus; determine a termination cause based on the last engagement activity and the post-engagement actions; and generate post-engagement metadata for the first user, the generated post-engagement metadata including the termination cause, wherein the processor of the apparatus is configured to perform rudimentary data interpretation locally, but further configured to send the sensor data for computationally intensive sensor data interpretation to the content provider for processing over the network. a network interface configured to be connected to a content provider via a network ; at least one sensor configured to record sensor data at a first location; a user interface manager configured to receive user input from a first user; a memory ; and a processor configured to execute instructions stored in memory, wherein execution of the instructions by the processor is configured to: detect that the first user has terminated engagement with the apparatus; record a last engagement activity before first user is detected as having terminated engagement with the apparatus; determine that the first user has performed post-engagement actions at the first location based on the sensor data from the at least one sensor recorded after the first user terminates engagement with the apparatus; determine a termination cause based on the last engagement activity and the post-engagement actions; and generate post-engagement metadata for the first user, the generated post-engagement metadata including the termination cause, wherein the processor of the apparatus is configured to perform rudimentary data interpretation locally, but further configured to send the sensor data for computationally intensive sensor data interpretation to the content provider for processing over the network. detect that the first user has terminated engagement with the apparatus; record a last engagement activity before first user is detected as having terminated engagement with the apparatus; determine that the first user has performed post-engagement actions at the first location based on the sensor data from the at least one sensor recorded after the first user terminates engagement with the apparatus; determine a termination cause based on the last engagement activity and the post-engagement actions; and generate post-engagement metadata for the first user, the generated post-engagement metadata including the termination cause, wherein the processor of the apparatus is configured to perform rudimentary data interpretation locally, but further configured to send the sensor data for computationally intensive sensor data interpretation to the content provider for processing over the network. <EOS>
