Scientist develops app to read moods
FEELING blue? A bit down in the dumps? Well, scientists at Oxford University believe they have an answer.
A smartphone app has been developed that scans your facial expression to judge if you are feeling depressed, stressed or plain angry.
It then uses that information to recommend the perfect food to lift the spirits, or quell anxiety.
The app, developed by scientists at Oxford University, is being trialled for the first time this week ahead of a rollout later this year.
Professor Charles Spence, an experimental scientist, developed the app to scan the face for signs of emotions, such as downturned lips and eyes and frown lines.
It can even pick up on hidden feelings that a person may be ignoring.
“Face mapping can provide a more accurate and objective assessment of a person’s mood or emotional state than they can,” Spence said.
“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. The reverse of this is also believed to be true; that food can have a number of effects on your mood.”
Spence has worked with Heston Blumenthal and the former El Bulli chef Ferran Adrià on involving the other senses in the pursuit of taste and runs the University of Oxford’s Crossmodal Research Laboratory.
He said that mood and emotion can affect the “sensory discriminatory aspects of tasting”, which is why people often stop eating following a break-up or when they are grieving, because food does not taste as good.
“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,” he said.
The app, developed by Spence in conjunction with the UK food delivery service Just Eat, detects anger, disgust, fear, surprise, sadness and joy and makes menu suggestions according to what it finds.
For example, an angry face suggests that a person is stressed and so would benefit from calming foods, such as dark chocolate and nuts, which contain magnesium. In contrast, people who are excited may benefit from blood sugar regulated foods such as whole grains and legumes.
Nutritionist Ruth Tongue said: “Not only do our moods affect the foods we choose to eat, but the foods we eat can in turn help us to feel happier, energised, relaxed, focused or fired up and ready for the day.
“It’s important to recognise the relationship between the foods we eat and our moods so that we can ensure that we’re looking after not only our physical, but also our emotional wellbeing.”
Graham Corfield, UK managing director of Just Eat, said: “We know that mood plays a part in what we choose to eat, so innovations like emotion analysis technology serve a real purpose.” — The Sunday Telegraph
