I resumed PC/Mac gaming when friends suggested that I'd try out Guild Wars 2 and play with them. Since I've been mostly a console gamer for the past years, I didn't feel comfortable using my keyboard to play games, it's just not as immersive.
I tried other alternatives like the PS3 Dualshock, the SpaceNavigator 3D mouse, the Alphagrip iGrip keyboard, iPad gestures, ... and a Logitech G13 keypad with a Logitech G600 MMO gaming mouse was the only thing that felt usable, still not perfect.
That made me think, I had these awesomely sensitive Eigenharp instruments with 3D control over every key, very light pressure, natural hand positions and more than enough keys. It suddenly made sense that they would work just as well for gaming as for music. I thus created an EigenD extension agent that allows the mapping of any Eigenharp key to any keyboard key, as well as mouse movements and mouse button clicks. All of this can of course be further configured with different thresholds, sensitivity settings, multi-axis velocity-based triggering and much more. Currently this agent is only available for MacOSX, but it shouldn't be hard to add Windows support. Those interested can find the source code on GitHub: https://github.com/Eigenlabs/EigenD-Contrib/tree/master/sysin_events
As you can see in the video below, the Eigenharp is indeed a wonderful game controller. While I don't expect people to buy the Eigenharp just for that, existing Eigenharpers now have one of the best game controllers available, all the time while training muscle memory for their musical instrument.
