brainhelper

"Racking one's brain" is a common phrase used when faced with the mental effort of solving a porblem. The interactive, wearable Brainhelper funtions on a basic principle; it does not offer solutions but provides support for complicated thought processes. A mechanical hand is attached to a metal box to be worn at the back of the head. The brain's activity is measured by EEG and the hand reacts to this, slowly moving across the head and massaging the scalp. The intensity of the massage depends on the user's mental activity.
