You can use a Kinect to just play games - but there is more fun and perhaps even profit to be had from putting it to other uses.
So what else can you do with a Kinect?
A device that measures the depth of every point in a scene may not seem to have much potential but this isn't the case. Inventive uses of a Kinect fall into a number of different categories.
You can use it to track a human and then respond to movements and gestures as a free from user interface.
You can use it to create something artistic by responding to depth or human movements.
You can use it with robot as a navigation and device.
You can use the depth map to create virtual and augmented reality applications.
You can use it to make 3D measurements and model construction
And no doubt there are many more.
