Abstract

A methods and systems for use of an input device with a display system are disclosed. In an example embodiment, a projection device configured to project a displayed image is provided where the displayed image includes one or more selectable items. The projection system further includes an input device which may be movable in free space and may be configured to point to the selectable items. The input device may be enabled to provide a double-click input to effect one or more changes in a graphical user interface that corresponds with a selection of a particular one of the selectable items at which the input device is pointed. The double click input may be identified such that movement of the input device after initiation of the double-click input may be ignored by the graphical user interface until completion of the double click input.
