If there is a game or another application already running, the Wii U GamePad's HOME button ring will flash indicating that there is an incoming call. The idea of the feature was originally seen in the introduction trailer of the Wii U in E3 2011. However, users weren't also able to use the service as a multitasking application, therefore not having the ability to make video calls without interrupting game play. Nintendo had announced a desire to make video chat possible through multitasking, but it was never implemented.
