Japanese goggles latest advance in the battle of the bulge
An image processing system that changes the size of a piece of food when it is picked up off the plate and moved towards the person's mouth has been developed by the researchers at the University of Tokyo's Graduate School of Information Science and Technology.
The latest creation in the battle of the bulge is a pair of goggles that are equipped with video cameras linked to a computer that is able to manipulate the images.
The computer is able to make the food appear as much as 50 percent larger or 33 percent smaller than its actual size.
To make the illusion even more convincing, the processor is able to make the person's hand appear to be the same size as normal.
"By changing the size of the food and scaling it up we have shown that participants eat about 10 percent less over the course of a day," Takuji Narumi, an assistant professor working on the project, told AFP.
