A host of companies, including Microsoft, have been working to create a new way of interacting with computers: motion sensing technology. With everyday movements like drawing, waving, and rotating, users can control functions on their computers. Many are entering the field; a company called Leap Motion, for example, has created technology that converts any screen into one that can be controlled by waving all ten fingers. The device can be useful, some say, for surgeons that want to interact with 3D medical data, engineers who want to mold an object, or everyday users who just wants to sit back and scroll.
