Far far too complex.
How about a button on the Pi to activate that room?
I think you need a girlfriend or a better source for porn. You sir, are bored.
It is complex, but if I can get that working I could also do some other cool things. The likes of which I can't think of right now. A button would work, but I'd just like it to do it without having to do anything. I'm tired of bluetooth connecting, pausing and unpausing and missing parts of a book or podcast because I went out of the room and forgot to pause it.
Nah, I'd just like a system that works like I described. And I also want to learn some more programming!
What about a kinnect in every room. Could track exactly where you are and you could train it to recognise routes to work out where you're going.
True, or a cheap webcam. There are a lot of ways to do it I suspect. Just want to find a cheap easy way!
What about motion detectors like the ones you would use for a security system? I have a few of those around here, that might work pretty well.
Second hand kinnects are cheap. 3d vision would be better for tracing your route, and there's a nice API for it all.
They can tell where you are, but not necessarily where you're going.
