This is just an FYI for users of Microsoft Kinect and Mobile Cameras. http://www.businessinsider.com/micr...s-to-count-people-in-your-living-room-2012-11 New Microsoft Patent Uses Kinect And Mobile Cameras To Count People In Your Living Room A new Microsoft patent will allow the company to remotely surveil, and effectively count American citizens as they order online or cable pay-per-view from the comfort of their own homes. From the patent: http://appft.uspto.gov/netacgi/nph-...04".PGNR.&OS=DN/20120278904&RS=DN/20120278904 A content presentation system and method allowing content providers to regulate the presentation of content on a per-user-view basis ... Consumers are presented with a content selection and a choice of licenses allowing consumption of the content. The users consuming the content on a display device are monitored so that if the number of user-views licensed is exceeded, remedial action may be taken. The patent, submitted on April 26, 2011, and passed on Nov. 1, 2012, essentially allows the company to remotely turn on any cameras, be they mobile or from something like the XBox Kinect, and count the number of 'consumers' watching licensed content. What Microsoft dubs 'complex algorithms' will not only count how many people are consuming that Mixed Martial Arts Championships, but also for how long they consumed the content, paving the way for charging users for half or even quarter uses of content. From the patent: In the case of the mobile display device, the display 105 is generally designed for use by one person but it is possible that more than one person may be able to view content on the display 105. As such the consumer detector uses data from the camera or capture device 102 to determine the number of consumers. In one example, camera 102 is an RGB imaging camera and the consumer detector analyzes one or successive images from the camera to ensure that the licensed number of users per view is enforced. "Enforced" means the patent also gives licensers using Microsoft's surveillance 'product' the right to 'shut off' content if an unauthorized amount of users start to watch. So you may want to tell the folks you invite over for the next fight to shut off their cell phones and remove the batteries prior to beginning the show.
