Braintooth, evolution from bluetooth
(ToDo: Horrible name, search for another one)
What: The same way you sync your mobile phone with your car so it uses its sound system, you'll be able to send instructions with your mind to a certain sync'ed gadget. For example, you are driving in your car, and you want to select the next song; you just "think" about it and your sound system receives the info and acts. Same thing as "OK Glass, take a photo", but you just think about it.
Conflicts: two people sending mental instructions to the same gadget.
