A special pair of glasses designed to trick the wearer into eating less was presented by a team of researchers at the University of Tokyo.
The glasses use computer technology, including the so-called “augmented reality” to make food appear larger or more tasty, so that the wearer would eat less than normally. For example, a plain snack could be shown as a chocolate cookie while biscuits can seem larger than in reality.
A camera mounted on the glasses analyzes the object in the hand of the user and then it changes its apparent dimensions, making it seem larger, while keeping the size of the hand unchanged.
The researchers say that first tests showed that if biscuits were increased by 50 percent, people would eat nearly 10 percent less.
“How to fool various senses or how to build on them using computers is very important in the study of virtual reality,” said one of the professors involved in the research. “Reality is in your mind,” he said.
