Received mine in the mail about a week ago. It's a novel device, but better software really needs to be developed for it. If you download the right app from the airspace store (this is leap motion's app store) you can use the device as a mouse for all your desktop applications. But using it like this is really frustrating. Tasks like clicking (which is done by pushing your finger in towards the screen) take like 5 seconds, which frankly is counter-productive.
My bottom line for using this in the exam room is when I can keep my fingers on the keyboard, raise my right index fingertip about a cm above the keyboard to move the pointer to somewhere on the screen, and raise my left index fingertip to click.
It's definitely not there yet. In fact, you have to keep your hands about 4cm above the device otherwise it won't pick up your fingers very well (I'm not sure why this is). I have doubts as to whether Leap Motion will ever get there. One issue with the technology is that of infrared interference. Computer screens give off enough Infrared Radiation to dampen the precision of the device. So you have to keep the sensor far away enough from the screen. In the picture I posted above, the guy using the device has the Leap Motion controller in between his keyboard and computer screen. It's a misleading picture. The best place for the device is before the keyboard. And the best way to use the device is with t-rex arms (though this can be fixed with better software).
Anyone else care to relate their experiences with Leap Motion? Maybe I'm doing something wrong.
This article summarizes how I feel about purchasing leap motion.
