  • I entered that answer and it was marked as incorrect. So, it has to be one of the other answers. Which one do you think it is?

  • No, all of the above can't. and I think next most appropriate answer is Radio signal strength and it can't be Sonar. Sorry for previous comment. I just read it.

  • But I'm seeing sonar mentioned for indoor GPS tracking. E.g., https://forum.arduino.cc/index.php?topic=56676.0 Are you sure it's not all of the above?

  • The next most correct answer is RSSI. A hybrid of WiFi and RSSI is sometimes used for indoor tracking. "All the above" is not right because of Sonar.

  • I'm torn because I think that computer vision IS a correct answer. Are you sure that sonar isn't (toward making all of the above correct)?
