Typically, a computer is operated using a mouse and a keyboard. However, a small percentage of people have disabilities that prevent them from using these devices. How can they use a computer? With their face! Assistive technologies like eye tracking allow a person to control a device with other parts of their body. In this proof of concept, you use your "laser clown nose" to guide a target that presses buttons. To try this demo, you'll need to allow Scratch to use a camera connected to your device. After that, start the project and the target will follow your head movements.
