I can see right through you: Microsoft patents glasses that read emotions

Microsoft has patented internet-connected glasses which can detect and interpret the emotions of people in the wearer’s field of vision. The application for a “wearable emotion detection feedback system” was filed in October 2012 and awarded this week in the U.S.. The filing says that the wearer can decide who in their field of vision to analyse - individuals or groups - without their knowledge. No potential uses are specified, but they could be useful in the business world during job interviews, or by border guards while questioning travellers.

Microsoft regularly applies for and receives patents as part of its business practice; not all patents applied for or received will be incorporated into a Microsoft product.

The gadget would work by using cameras to pick up visual information from a subject, and a nose bridge-mounted microphone to gather audio cues. Subtle variations in a person’s demeanour - such as speech rhythm, speed of gestures, and body posture - would then be analysed to draw conclusions about a person’s emotional state. Part of the filing said that context would also be important: “For example, if a subject plays with her hair in a social situation, such as a date, this behaviour may indicate friendliness or interest. However, the same behaviour in a business situation may indicate boredom.”
