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.
Very true. I'll do some checking on the Kinect. Thanks for the heads up!
Just busting your stones there, quad boy. :-P
You know, my brother in FL does home audio, alarms - all that low voltage stuff. I am surprised the hoity-toits down there haven't asked him for that very thing like you are trying to do. Maybe that could be a promotional idea for him. Let me know how you get on. ;-)
Add a speaker to your quadcopter and have it follow you where you go blasting music down above your head.
I have been thinking about this for a while but never really got stuck into it. My plan was to use my phone with NFC token at certain points of the house that will change the Sonos speaker as I moved around. There are lots of NFC software options that can be programmed to do simple tasks, the biggest hurdle for me is making it work with the Sonos software.
I think I need to go and by some NFC tokens now.
What's the range of nfc? Would you deliberately have to swipe into a room to make it work?
Normal range is between 2cm and 6cm so if you added a token to a door frame you could possible walk next to it with your phone in your pocket, all you have to do is remember to do it.
