Disclosed is a user device comprising a display having an available display area, a network interface, and one or more processors. The network interface is configured to transmit and receive messages between the user device and a communication network in an instant messaging communication session. A client application executed on the one or more processors has a user interface capable of operating in a conversation mode or in an engagement mode. The client application is configured to detect a condition indicative of the level of engagement of the user by analyzing the user's activity at the user device and responsive to the detected condition to modify the client user interface, when configured to operate in one of said modes, to operate in the other of said modes instead. |
