Computer scientists have created a brain-computer interface that can read your thoughts. It allows you to stroll down a virtual street. All you have to do is think about walking.

The technology detects brain waves by using electrodes placed at strategic points on the scalp; they are positioned over brain areas known to be involved in moving specific body parts. The computer can then distinguish between signals corresponding to different types of movement.

Previously, accurate detection of local brain activity required electrodes to be implanted in the brain.
