Now this is rather weird, but researchers have successfully come up with a way to make your cameraphone function as a mouse - whenever you’re not receiving or making a call, naturally. This software relies on Bluetooth technology to keep it going, and enables the cell phone to interact with public displays. For example, users can obtain product information or purchase tickets simply by using the camera. Unfortunately, this idea still requires a great deal of work before it is ready for a commercial release since the image capture and image processing rate on the cell phone is rather slow, and you have to deal the with the lag.
