Sony Computer Entertainment America has filed patents for software which is able to recognise emotions, including, laughter, sadness, joy, anger and boredom.

Uncovered by Siliconera, the patents are not limited to home consoles, although artwork filed by Sony depicts a PlayStation 3 and Bravia TV.

The patents may be related to Sony’s PlayStation 3 motion-tacking technology, first revealed at E3 this year, which follows player movement and can detect facial expressions as well as spatial recognition.

The technology also sounds similar to Microsoft’s Project Natal, and in particular Lionhead’s demo of Milo and Kate – software that as well as following movement, can detect emotional responses through facial and voice recognition.
