Is it possible to build the following scenario, and if so, can anyone point me on the right track?
I have a person and I want to place small transceivers in various places on his body. The transceivers would all be able to detect their distances from each other using some sort of wireless transmission and then send those distances to a small wireless processor attached to the person's hip. The processor would then use the distance variables to determine the relative positions of each transceiver in 3-dimensions.
I've tried to research this and I've found a lot of sensors that can determine distances to a random object in its field of vision. But I would like to know the distance between 2 discrete objects that both move around. I was thinking maybe I can send a wireless transmission with a timestamp and a serial number and then the receiving device would record that information along with the current time stamp. Maybe the transmission time could then be used to calculate the distance?
Are there currently transceiving devices that can do this? I am less concerned about the processing and mostly concerned about the data capturing.
Thank You.
