Something I've always wanted to work on but now that I've grown older after ~47 years of playing computer games I'll need to pass on to the next generation: A Natural User Interface To Games.
Right now, there's a translation layer in the way -- your controller, keyboard/mice, wands all get translated into in-game actions, and in different ways from game to game. You always have to spend time learning this translation. Ugh.
Come on, folks. Build me a haptic suit or something similar that I can use to control my avatar. It'd track my fingers, obviously. Of course, a good high-resolution VR faceplate with no cables dangling is a requirement.
Every game would have an obvious interface, and you'd get some exercise also!
Build this for me before my time passes!
(It's probably dangerous for me to say this, but I could fund this endeavor.)
