Abstract
A multi-user computing device, such a communal computing device like an interactive digital whiteboard, can execute single user aware ('SUA') applications and multi-user aware ('MUA') applications. Instances of SUA applications execute in the context of a single user. MUA applications can execute in the contexts of multiple authenticated users simultaneously. A multi-user aware OS platform authenticates and de-authenticates users of the multi-user computing device. The multi-user aware OS platform provides notifications to MUA applications when users are authenticated and de-authenticated. When a new user is authenticated, MUA applications begin executing in the context of the newly authenticated user and any other previously authenticated users. When users are de-authenticated, MUA applications stop executing in the context of the de-authenticated user but continue executing in the context of the remaining authenticated users of the multi-user computing device. Data associated with the de-authenticated user is removed from the multi-user computing device.
