This spring, HP announced that it will start bundling Leap Motion controllers with some PCs and that it plans to one day embed the technology in devices. In the meantime, anyone will be able to buy a controller off the shelf and plug it in as a peripheral. Out of the box, the device will allow users to control some basic computer functions, like cursor movement, but improving existing systems is not really the point. "If we're successful and build something that is a fundamentally better way to interact with a computer, there are essentially an unlimited number of use cases," Buckwald says. "Eventually, anything that has a computer could be controlled with it—every laptop, every desktop, every smartphone, every tablet, every TV, every surgical station, every robot, potentially even a Leap in every car."
