a friend of mine became a quadrapalegic when he fell into his pool last year. he came out of a coma and now has a similar motorized chair (300 lbs.+).
one short breath - left
one long breath - forward
one short inward breath - right
one hard inward breath - stop
hit his head to the left - engage or something
hit his head to the right - i forget
i don't think it can go for more than like an hour though without recharging.
he can now move his arms slightly and with enough work, doctors say he can regain everything he had before.
really quite a shame, he was an avid dirtbiker/ 4wheeler/ mechanic. he is lucky to have survived, the miracles of science never cease to amaze me.
and yes, people help him smoke butts, and occasionally toss a few back (nips) or puff one.
hey, i would want the same if i was a fuckin quadrapalegic. another thing, he says 'it' still works, but he obv has no feeling - so fuckin shitty.
sorry for the sad story, just wanted to share my buddy's crazy ass chair and how it works (I could totally see him doing something similiar, except he would NEVER get lost on the way there lol).
