In this research, the application to the work measurement in shipbuilding was examined as a concrete application example of a wearable system. Authors made the work content input system that the worker input by using the voice recognition, the speech synthesis and the positional measurement system of the worker that used a magnetic frequency. They were processed with the computer that the worker wore. The work analysis of the current state could be done at once for the acquired data, and effectiveness was found as a prototype system of the work measurement in shipbuilding.
