I think what he means is like the natal system, just for the psp instead. It could be possible but for it to be easy is not guaranteed. If you looking for a natal type idea then it would have to be more of a motion tracking type system, not like an airwick, An airwick would work for if you had, lets say, an xbox and you would like to attach it to the power button so when its activated it would turn on. Although if you were to reduce the intensity of the motion thingy, then it could work like a finger swipe type of thing, where you swipe your finger fairly close to the senser or whatever it is, then theres is hope but if you want a natal type idea then your most probably going to have to do ALOT of work. like ex: programming for the motion detecting, small enough motion detector and all the bugs to work out because I am guessing from common sense that something of that complexity will have glitches and bugs. It is possible that it could work, but i am unsure of anybody doing that or researching how to do that. If you want to get on it you could be the first!
