im working on my examsproject and would like to know the position of three users in a room ..
my first idea was to give them each a gps module , but it turned out that gps is not messuring close enough..
my next idea was that i could use three different wiimotes and then use three arduino+bluesmirf modules to track on their individuela signal level ... and then calculate their posistion based on trilateration..
but before i order 3 sets of bluesmirfs .. i would like to know if their is anybody at this forum that have done something similar ?
is it possible to read the signal level from the the three different wiimotes ?
ill probably buy them anyway as i am in a hurry to get startet but ,,, i would still like to be pointed in the right direction
Dont you mean Triangulation?
If it works or not all depends on how accurate their signal strength reporting is.
Also I’d go with 5 stations instead of 3. The more you have the greater the accuracy.
Oh and before you buy, BlueSMiRF wont do what you want.
AFAIK they are just serial modules. Data goes in, data comes out.
No signal strength indicator nor the ability to scan for bluetooth devices.
i dont know if triangulation or trilateration ( http://en.wikipedia.org/wiki/Trilateration ), is the best way to determine position within an area, but is it not important that i get the distance from the fixed antennas to the tag which position that i want to calculate ?
Hmm Trilateration seems to be technically the correct word to use.
They are basically the same thing though. Same idea.
