An Evaluation Method of Temporal Change on Mental Model

Abstract

The mental model of product, system and so on was constructed based on the main information, sub information and related information which were proposed and defined. An evaluation method of mental model can evaluate mental model quantitatively based on the difference between ex-post evaluation and pre-evaluation of mental model using the three information and evaluation items. Structural model and functional model of mental model were also examined from view point of temporal model. The pre-evaluation of mental model was changed into the ex-post evaluation of mental model from view point of temporal change. The effectiveness of the method was validated by four participants. The method was evaluated highly because of constructing mental model corresponding to their feeling or idea. If the structural model and functional model are known or unknown, the combination of two models can show how to design using cues, operation etc.
