The infra-red signal is picked up by an opposing player’s receiver and then an Arduino hooked up to a T.E.N.S. machine delivers light electrical shocks to various parts of their body. This gives a palpable sense of being ‘hit’ without doing any damage. There is a bit of a delay while the voice commands are piped to the cloud and received back again, making it not-particularly-instant, but it’s still pretty cool!
