“Researchers at two UK universities have developed prototype software which enables a camera phone to act like a 3D mouse and control a computer,” according to an article in “Camera Core.”
The researchers will present a paper about the software at the International Conference on Computer Vision Theory and Applications in Madeira, Portugal this month. The cellular phone connects to a computer via Bluetooth and moving the phone moves the cursor on the computer.
The article says, “The user can interact with the computer both by movement and with the phone’s keypad. The phone can be used to perform tasks such as selecting an image with a phone button, and then resizing the image by moving the phone either away from the screen to make it larger, or towards the screen to make it smaller.”
“Camera Core” says the researchers are exploring other applications, such as using a camera phone to interact with video advertisements. The concept of moving cellular phones to control computers and other devices isn’t new. I’ve read about research in this field for many years.
