Kissing computer game

An American student has invented a computer game controller powered by kissing.

Hye Yeon Nam made the device with which two players at a time control the path of an on-screen bowling ball by locking lips with one another.

The brainbox said she invented the unusual gadget to get more emotion into gaming.

She explained: "I had been making a lot of different installations and a lot of different devices. All the time, I wanted to show people's behavior through my work.

"How can I foster ... a positive feeling with this work? Kissing is one of the ways that people express their love, so with this, they kiss more."
