A content-management interface is implemented using superposition of graphical "widget" elements onto an on-screen display of the real-time image of a user. The widgets are motion-sensitive control elements which are responsive to user movement that produces motion of the user's displayed image at an on-screen location associated with that widget. The user can operate the widget virtually, for example by moving his hand over a widget, or pushing a widget along. Meta-data descriptive of the content to be managed is mapped onto widgets, enabling the user to interact with the meta-data, notably by changing it or by selecting content with reference to it.
