The purpose of this work is to apply the behavior model of skills to the interface design for developing more efficient usability testing. In the first half of this paper. experiments were carried out in order to observe the skills of automatic machines in the manufacturing industry and the model of the proficient skills has been constructed. The interface design has been generally analyzed and studied by use of the model in the latter half.It is found that the model has the possibility to be applied to the interface design of automatic machines. The multi-media display system that can do the protocol analysis more efficiently by use of digital protocol data has been developed through preparing these experiments.
