Pizza Hut recently introduced the world's first "subconscious menu". You're given a tablet and all you have to do is stare at a list of toppings. The tablet "reads your mind" and chooses your pizza for you.

This technology was first tested in Pizza Hut's UK restaurants.

So you sit down and stare at the list of 20 toppings. The tablet will choose what it thinks you'll order from 4,896 possible combinations. Sounds spooky, doesn't it? But it's pure science.

First, you follow the Pizza Hut logo with your eyes so the menu recognizes your eye movement. The menu will then reveal icons of 20 toppings on the screen, among them chicken, chorizo, and pepperoni.

Pizza Hut said in exactly 2.5 seconds, the subconscious menu knows which ingredients your mind and eyes have been looking at longest.

The menu then uses a special mathematical algorithm to identify your perfect pizza from 4896 possible ingredient combinations.

The tablet uses eye-tracking software from Swedish eye-tracking firm Tobii Technology to figure out what it is you want. The tablet's cameras and graphic processors measures the infrared light reflected from the corneas of the eyes and can determine where a person is looking.

The time you spend looking at a certain topping tells the tablet what it is you want.

Pizza hut said tests of the new menu have been "incredibly positive." It claims 98 percent of people were happy with their recommended toppings.

If you're not satisfied with your selection, simply look at the re-start button to re-start the process.
