I bet your helmet is not as cool as the MindRider: this is a futuristic helmet system that mind-maps your best routes and shows your levels of engagement system. The product has MIT written all over it. The MindRider app maps and and tracks your engagement level (through a soft sensor embedded in the helmet’s foam) and lets you share your mind maps with others. MindRider uses color-coding to visualize your engagement level. It connects to your mobile device via Bluetooth (compatible with iOS and Android devices).
Your mind-maps will have green and red spots to show relaxation and concentration periods. You could share your mind maps with your friends or even your community. This interesting system is on Kickstarter right now.
