  • Nowadays, VCR(Video Cassette Recorder) has various functions, but users use to fail operating these function because of the complexity of operation. The process of operating VCR contains user's cognitive characteristics. It is necessary for designing it that we must identify a user's mental process in the behind of operational behaviors. This effort, as well as considering physical dimensions and layout, can make VCR easy to use. In this research, VCR remote controller are analyzed by the cognitive method and experiments. Three types of VCR remote controllers, cognitive VCR models and two non-cognitive(typical) VCR models, are adopted as experimental objects to test the validation of the suggested user's cognitive mode of VCR. As results, when VCR was operated by the cognitive prototype of remote controller, task completion time was reduced to 80.5%, and the number of errors was reduced to 96.8%.
