Using the human hand as a powerless infrared radiation source
Apr 2021, phys.org
The future is so obvious once it happens.
The idea of your fingers manipulating computer screens floating in mid air seems pretty natural. I never thought of my finger as a remote control, but it does make perfect sense. This also reminds me of the Nintendo Wii hack from many years ago, where you place the Wii controller in a stationary position, and have it read an IR light pen as you draw on a surface with it. The light-point is followed by the Wii, and translated into lines on a projected screen. You use the Wii backwards to write on the projected surface in real time. Graffiti Research Labs took this a step further with their Laser Tag project. Now we can imagine doing that with our fingers. No Wii necessary, only some basic intelligence in your camera, and it will be able to learn how to see your fingers and take direction from them.

Speaking of Laser Tag...
