Question for EE geeks. I want to have something like this. Sensor A, Sensor B, Sensor C, let's say up to 16 sensors. Each separated from each other by no more than 2 meters at any given time. Each sensor needs to be small enough that if you attached it to the body and tried to run you would not feel encumbered. So maybe up to the size of a watch. Powered by something like CR2032 battery. Then there is a base. The base can ask any of the sensors how far away they are from a given peer at any time. Base can be stationary and plug into a wall.
Questions: - What is the technical term for something like this? - If something like this exists, can I get the precision of 0.1 cm and the ability to query 1000 distances per second for a reasonable cost (let's say under $1000)? - Assuming the answer to the previous questions is that it is technologically possible, but not for the given price. Suppose a demand arose for a system like this to where you had, let's say, a million potential customers. Would it be economically viable to manufacture a system like this for less than $1000 for a base + 16 sensors? If it is not obvious, and also to keep the discussion on topic, I do want to be able to use Linux to control the base and collect the data. I have initially thought of it as a tool to evaluate running form, but the applications are numerous. E.g. you could use it to detect improper sitting posture and sound an alarm until the person adjusted his position. -- Sasha Pachev AskSasha Linux Consulting http://asksasha.com Fast Running Blog. http://fastrunningblog.com Run.
