You could be seeing different online advertisements depending on your emotional state.
A patent Microsoft filed in December 2010 was made public only last week that reveals a rather interesting advertising engine. Instead of showing targeted ads by only tracking the user’s online activities, the patented technology can also recognize the user’s emotional state based on facial expressions, speech patterns, and body movement.
Although in its patent Microsoft explains that the mood of the user can be collected over “client devices” such as smartphones, laptops, PCs, and gaming devices, it’s likely these mood-based ads could be facilitated with Microsoft’s Kinect. The motion sensor can already detect speech, and gestures. Nevertheless, Microsoft has not confirmed if the company would be actualizing the patent at this point in time.
