Going on a date can be a nightmare for the best of us. But now a pair of 'social X-Ray' glasses
promises to tell you exactly what the other person is thinking-and when you should stop talking.
The glasses have a built-in camera which monitors the other person's facial expressions and matches
them up with 24 known features which convey emotions. It will then tell the individual via an earpiece and
lights on the glasses what their date is thinking. In a traffic light-style system, a red light means negative,
yellow means they are a bit interested and green means your date is happy. The glasses are under
development at present by researchers at the Massachusetts Institute of Technology's Media Lab.
They say that wearing them during a conversation with another person is like having an 'extra sense'
that they are bored or losing interest.
The eyewear was developed for people suffering from autism (孤独症) who have much difficulty
interactingwith others, but now the team behind it has seen wider applications. It works thanks to a
camera the size of a grain of rice which is put into the glasses frame and connected via a wire to a small
computer which can be attached to the user's body. The camera monitors how long and how often 24
'feature points' appear on the subject's faces which are then analyzed by software developed by the MIT
team.
This data is then compared with a bank of expressions and the computer tells the wearer what is
going on via the earpiece and the traffic light system.
So far the glasses are still a job in progress and have been accurate just 64 per cent of the time, a
figure which is expected to improve with further tests.
