We've got to hand it to Oxford -- one of the worst feelings in the world is being hangry, and scientists over at Oxford University seem to know that struggle. Perhaps that's why they've developed an app that actually tracks facial expressions in order to a) assess somebody's mood and then b) suggest what kind of food will quell your stress, anger, fear or other bad feeling and turn it into something more positive and productive.
According to Telegraph, the food delivery service "Just Eat" has partnered with Charles Spence, professor of experimental psychology at Oxford, in order to develop the technology that has the ability to monitor users' moods and then suggest proper nourishment accordingly.
At the moment, the technology is about to embark on its trial run, before hopefully rolling out officially to the public later this year.
Here's how it works: basically, the app will scan your face, and pick up on little hints and clues that indicate somebody's state of mind and mood. For instance, a downturned mouth compared to an upturned one is probably indicative of a negative feeling, even if you yourself are unaware of feeling poorly.
Have you ever broken up with somebody and totally lost your appetite? Or do you realize that sometimes when you're overtired, or overstressed, your preferences for what you want to eat change?
According to Professor Spence, mood and emotion definitely affects what he refers to as 'sensory discriminatory aspects of tasting.' His app will hopefully be able to spot this happening, and get you right back on track.
"Face mapping can provide a more accurate and objective assessment of a person's mood or emotional state than they can," Professor Spence said to Telegraph.
"Often people are not able to say how they are feeling or just don't feel they want to. After all, we might know that we are in a bad mood, but not know why.
"There is a growing body of evidence that demonstrates that your mood has a significant impact on your taste and smell -- it can deaden or liven the effect of both -- a reverse of this is also believed to be true, that food can have a number of [effects] on your mood.
"This is at the very cutting edge of what technology and science can do but in the future it is likely to become much more the norm."
We can't wait to try it!
