Using windowed user interface z-order with collaboration data for improved management of acknowledge of incoming instant messages

摘要

A method, apparatus, and computer instructions for predicting the availability of an instant messaging user in an instant messaging system and providing that information to a message sender. The present invention analyzes a user's collaborative data to determine the user's availability to respond to an instant message and monitors z-order movement of an instant messaging window on a user's screen to determine how much attention the user is paying to the instant messaging. The instant messaging application then uses the collaborative data and the z-order information to predict the availability of the user to respond to the instant message. This information is subsequently displayed to an instant messaging partner in the partner's instant messaging window.
