Home automation is fun, but being able to turn your lights on and off from your computer isn't really all that practical compared to a good ol' fashioned light switch... until now.
what I propose is a watch that detects which way your arm is pointing, it also has a small mic inside that recognises
when you click your fingers. Just point at an appliance and click your fingers, the watch relays the information back to the computer which turns the appliance on or off.
some ideas to achieve this (feel free to add your own or elaborate)
1. blue tooth enabled watch with directional and location capabilities
2. tight beam infra-red with receivers at each appliance

Apparently a magnet (it should be humyn non-immunoreactive) can interface between your peripheral nervous system and the wonderful world of electricity [LoriZ, Jun 12 2006]
||If more appliances just offered a bluetooth interface, the user would be free to use whatever device is convenient for them. That could include a watch, phone, remote, PDA, whatever.
||I don't know how to click my fingers.
||good thinking, that small light on each appliance, means you can turn things on in the dark too.
||Print an infra-red visible barcode
on the devices and have a laser
barcode scanner in the device
||perhaps the watch could also incorporate a roll detector, so you can turn volume,dimmers etc up and down by twisting your hand clockwise or anticlockwise in the air.
