The invention relates to 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. Advantageously, the smart device will be equipped with an optical sensor for automatically detecting that it lies on a surface, measuring displacements of the device on said surface and emulating displacements of a cursor on the screen of the host device. Advantageously, the smart device will be equipped with a two axes gyroscope which will 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. Said zones are configurable through a graphical user interface. Gesture recognition features can be implemented. |
