System and method for monitoring and controlling a manufacturing environment

A method of monitoring and controlling a production environment, comprising:

• wirelessly transmitting an expected signal strength defining a signal strength of a transmitter measured at a predetermined fixed distance, wherein the expected signal strength is transmitted using the transmitter, and wherein the transmitter is associated with an object in the production environment;
• using a personal computing device to calculate a current distance between the transmitter and the personal computing device based on a received signal strength of the received signal and the expected signal strength, wherein the personal computing device is integrated into eye glasses configured to be worn by a human user, and wherein the personal computing device includes a receiver responsive to the transmitter;
• and
• switching a user interface displayed on a display device of the personal computing device from a first interface display to a second interface display when the personal computing device moves within a threshold distance from the transmitter.
