Abstract

This paper describes some results of a project that studied how multimedia can help the worker in an assembly task. The test case was a deep-cut assembly of a grid-anode for a cathodic protection system. A multimedia tool was implemented and compared with the conventional support method for the same task. The tool helps the worker by providing training and background information. During the task the tool acts as a guide and a set of well-defined instructions. The comparison of the methods was done by means of a field experiment. The results show that the use of the implemented tool helps to produce a slight increase to the quality of the work. However, the execution time of the work was not better when using the multimedia tool. According to a user questionnaire done in the test situation, the multimedia tool was more useful and easier to use, and gave the users more confidence than the conventional support method. It can be said that the use of multimedia support helps the worker to produce better quality in the task.
