New 3D face recognition software shows emotion after eating food

A computer program that reads human expressions may bring an about-face in marketing.

Dutch researchers using the software recently for a consumer test project seconded what wise men have always known: Sweets are the surest way to make a woman smile.

Some 300 women in six European countries were filmed as they ate five foods: vanilla ice cream, chocolate, cereal bars, yogurt and apples. Not surprisingly, ice cream and chocolate produced the most happy expressions across the Old Continent.

The story is too old to be commented.
