The Redmond-based tech major filed the patent for "a wearable emotion detection feedback system" in October 2012 and has been now been awarded the patent, suggests a public filing by the US patent office.
"Microsoft regularly applies for receives patents as part of its business practices; not all patents applied for or received will be incorporated into a Microsoft product," a Microsoft spokesperson has been quoted as telling the Wall Street Journal.
How the smart glasses function
The wearer of the smart glasses, according to the filing, can determine who to analyse - whether an individual or a group, without their knowledge.
The sensors of the wearable device can measure changes in a subject's body temperature or pick up audio information.
The sensors, which include depth cameras and a microphone mounted on the nose bridge, pick up audio and visual information from a subject.
This would be processed for things like subtle variations in speech rhythm and amplitude, choice of words, type and speed of gestures, eye focus and body posture. All these are beamed through Microsoft's database and then an emotional determination would be relayed back to the user through the glasses.
