<p>One embodiment of the present invention sets forth a method for determining a chance that a user is present at a current time while a client device is tuned to a channel by monitoring a user input to the client device and determining a time when the user provides the user input. At the time when the user provides the user input, the chance is assigned an initial value. After that, the chance varies over time according to a first function. The chance that the user is present at the current time is then determined using the initial value and the first function. As a result, a chance of a user being present while a client device plays out media segments may be determined without incurring the costs of providing additional hardware and without requiring the user to register and unregister.</p> |
