Since the Kinect can identify individuals, expressions, words, and actions, it's likely that either the Kinect itself or the underlying technology will be used to automatically identify illicit activity like assault, robbery, illegal U-turns, speeding, and slacking employees. Cameras equipped with this kind of technology will count and track the movements of customers in grocery stores. They'll be able to track cars as they move through major intersections. It's only a matter of time before the Kinect or a similar device is used as a form of evidence in a criminal case. If it can watch for a happy face, it can watch for illegal drugs or other activity. I haven't found any links that talk about this possibility, but I think that because digital surveillance cameras are everywhere today, it's only a matter of time until they begin to have action-recognition technology bundled into them. People in major cities are caught on camera several times a day, every day. Soon, in addition to watching, the thousands of cameras that surround us will be watching for. What do you think?
I think the technology behind the Kinect means automated surveillance. In addition to the specific privacy concerns about the Kinect as it is, Kinect technology opens up the door to much more.
