There's nothing quite like the feel of real buttons. Despite the proliferation of digital keyboards, most of us tap the traditional mechanical keys when we can. The same goes for music creators, who often want the feel of traditional buttons and knobs while pumping out the jams.
Florian Born set out to create a modular interface for the iPad that would bring haptic feedback to the device through physical buttons, sliders, and knobs. Conductive aluminum controllers snap into place on the screen with the help of an aluminum and plastic frame. That frame has embedded magnets for easy and placement. When you touch them, the controllers pass on the electrical charge of your skin to the iPad, making it almost as if you're touching the screen.
All of this feeds into a custom app that can be programmed to work how you need it to. Pretty awesome. Check out the video for a look at the project in action.
