I have a piece of software that is voice activated and allows for extensive interactions with my computer, and peripheral programs. The downside being that it is limited to being in front of the computer. I would like to set up a system that allows me to move through the house, maintaining my contact, without having to wear a headset or other such device.
The goal is to have a small RFID tag I can carry (like on a keychain or in my pocket) that allows the system to track my location in my house. Then based on my location, it activates a unit nearest me in the room. The unit contains both mic and speakers and allows me to maintain contact with my PC.
Ideally each satellite unit in my house could ping for my RFID and turn its hardware on or off depending on its result. On an identical frequency they would all transmit back the receiver; which is hardwired into my PC. The PC would then just identify the base receiver as a headset. (since each satellite unit would turn off their hardware as I left there would be no need for separate frequencies)
This would allow for me to move throughout my house and the voice activation functions would move with me.
I think it would be best if each satellite unit could ping the RFID tag, and activate its wireless hardware when in range, then deactivate when out of range. That way once the main unit is plugged into the PC, it just registers as a single mic and speaker setup, like a headset or something.
Note: the reason for the RFID tag would be so I can be using the system in one room, and it is inaccessible in the others. That way the use of the system is limited to the location of the RFID tag. Any setup with voice activated mics would just make it accessible to anyone who can speak.
First, how possible is this? Second, how small do you think I could get each satellite unit (with a decent mic and speaker) as to be discreet (can't mess with the wife's decor mind you.) And finally, if it IS possible, what steps and components seem necessary to build it? (i.e. where do I start?)
