Despite its misleading headline, this NewScientist article gives a good description of a new type of user interface devices:

In the coming months, cheap headsets that let you control technology with the electrical signals generated by your firing neurons will go on sale to the general public.

Australian outfit Emotiv will release a headset whose 16 sensors make it possible to direct 12 different movements in a computer game. Emotiv says the helmet can also detect emotions.

Californian company NeuroSky has also built a device that can detect emotions: the firm says it can tell whether you are focused, relaxed, afraid or anxious, for example.

Assuming these devices do become successful, how can we come up with a good estimate on when it is going to happen?
