Japanese scientists have designed a novel vending machine which uses facial recognition to suggest drinks depending upon the customer's age and gender.
The firm behind the high-tech canned drinks dispenser has seen sales TRIPLE thanks to the new technology.
Developed by JR East Water Business Co, a subsidiary of railway firm JR East Co, the machines use sensors to determine the characteristics of an approaching customer.
'Recommended' labels will then appear on specific drink products and suggested products also change depending on the temperature and time of day.
"If the customer is a man, the machine is likely to recommend a canned coffee drink, since men tend to prefer these," the Sun quoted a spokeswoman as saying.
"If the customer is in there 50s though, that recommendation is likely to be green tea.
"A woman in her 20s will be recommended a tea drink or slightly sweeter product, since market research has shown that they prefer these.
"We thought it would make it a lot more fun for the customers to have this kind of interaction with our machines, that it would improve the whole buying experience," she said.
The Japanese company has so far tested one machine at a Tokyo train station, but plans to add five more soon.
