Abstract: A mobile device is provided for imparting spatially articulable control to an application program. The device includes a display for presenting the GUI. A spatial detection unit is configured to detect spatial movement of the mobile device and provides an output responsive to the detected spatial movement. A data processor is configured to provide a platform for executable code, and, monitors and provides the output to a communication channel. Executable code executes on the platform of the data processor. The executable code includes, an interpreter library which is operably linked to the communication channel and is configured to implement communication with the data processor to receive the output. The interpreter generates events relative to the interpreter library. A plug-in has an interface cooperatively linked to the interpreter library to receive corresponding generated events. The generated events are provided to a script interface of the plug in.
