Kinect was fun for gamers, and enticing to marketers for out of home installations. Now it’s time for “the Kinect on steroids,” known as the Leap Motion Controller. The controller is set to launch at retail on May 13th, but lucky individuals are getting to see it in action at SXSW this week with a host of compatible software by a range of developers. The early enthusiasm over the device is, at least partially, owed to its ability to detect changes in motion as small as 1mm, but this sharp precision is of concern as it can cause readings to be less smooth than desired. The technology is still in its infancy, and improvements are on the way via software developers, but as it stands, the Leap Motion Controller certainly offers something to look forward to as an out-of-home marketing must-have waiting to happen.
