MindRider is a helmet that translates electroencephalogram (EEG) feedback into an embedded LED display. For the wearer, green lights indicate a focused, active mental state, while red lights indicate drowsiness, anxiety, and other states not conducive to operating a bike or vehicle. Flashing red lights indicate extreme anxiety (panic). As many people return to cycling as a primary means of transportation, MindRider can support safety by adding visibility and increased awareness to the cyclist/motorist interaction process. In future versions, MindRider may be outfitted with an expanded set of EEG contacts, GPS radio, non-helmet wearable visualization, and other features to increase the cyclist's awareness of self and environment. These features may also allow for hands-free control of cycle function. A networked set of MindRiders may be useful for urban planning and emergency response situations.
