There will be an optical sensor that is located on the front of the helmet, where it touches your forehead and will be able to transmit a raw signal to the processing unit that is placed right at the back of the helmet. This processing unit will filter signals it receives from motion artifacts, transmitting such data sans wires to your mobile device via ANT+ or Bluetooth. It is not quite finished just yet, since it still remains under research and development status, but LifeBEAM is optimistic enough that there will be a large enough market for the smart helmet that they have already begun to receive pre-orders on Indiegogo.
