Which brings us to the Touch Toy. Wood says that the project was prompted by the idea of exploring ways of communicating with each other than just texting or phoning.

The Touch Toy is a small, key-fob sized device that has some kind of input mechanism, and some kind of output, Ken Wood said. At the moment, the input mechanism is giving the toy a gentle squeeze, and the output is a vibration.

(You can see where we are going with this already, cant you?)

The Touch Toy relays the input to your phone, connecting via bluetooth. Your phone then sends an instruction to another phone, which relays the signal to that phone's touch toy. The second touch toy then vibrates. Or, as Wood put it: "I squeeze my touch toy, my wife's vibrates".
