The Pointer

This project is an inexpensive, easy-to-use head mouse. The shell is 3D printed and features a clip to put it on a hat, visor, or maybe even a glasses frame.

To use the device, clip it onto something with the USB-C port facing outward toward the screen. Connect a USB cable and the device will automatically turn on. 

Move your head up, down, left, or right to move the mouse accordingly. After about two seconds of no movement, it enters a gesture mode where tilting left or right will left-click or right-click. If you stay tilted to the left or right, it will keep that button held, allowing you to click and drag. 

This is The Pointer, the version that focuses on gesture controls. The Setter is based on a sip-and-puff mechanism.
