A smart handheld device with a touch screen which can be used as a 2D or 3D mouse to control applications running on a host device. The smart device can include an optical sensor for, when a motion capture mode is activated, automatically detecting that it lies on a surface, measuring displacements of the device on the surface and emulating displacements of a cursor on the screen of the host device. The smart device can include a two axes gyroscope which can, when the motion capture mode is activated, measure yaw and pitch of the device in free space and convert changes in orientation measurements into displacements of a cursor on the screen of the host device. The touch screen is divided into zones and sub-zones to control various applications running on the device or on the host. The zones are configurable through a graphical user interface. |
