The present invention provides for an enhanced mouthstick device that allows. disabled individuals, having limited or no use of their hands, to independently, effectively and efficiently simulate computer mouse manipulation and input data in computer software applications. The present invention also allows disabled individuals, having limited or no use of their hands, to effectively utilize standard, commercially available, off-the-shelf GUI or windows-based software applications without requiring modification to the actual software application. The invention is comprised of three functional components mounted on a traditional mouthstick and a reception unit which is fitted to a computer display screen. The user manipulates the position of the cursor on the display screen by moving the StickMouse towards the desired position on the display screen. A signal transmitter unit transmits constant position signals which are received by the sensors on the reception unit. The reception unit calculates the location of the signal transmitter unit and converts the position coordinates into a serial bit stream which is transferred to the computer for display on the display screen.When the user wishes to perform a mouse button command input, the user utilizes the sip-and-puff procedures to trigger a pressure transducer which converts the user-induced, pneumatic signal into an electrical signal which is relayed to a signal. transmitter unit. The signal transmitter unit transmits the mouse button command signal to sensors on the reception unit where it is converted into a serial bit stream and transferred to the computer for execution
