Research of Human-Machine Interface Evaluation Based on Cogtool

Along with the development of interactive interface design technology, interface display becomes increasingly dynamic, multi-functional and logically-complex that increases the difficulty of interactive interface evaluation. The traditional evaluation methods of interactive interface cannot meet the requirements of interface evaluation due to its poor objectivity and economy. However, it is possible to predict the cognitive process of users by constructing human cognitive model as the development of cognitive psychology, and the interactive interface evaluation method based on the cognitive process of users is of feasibility and utmost urgency. This paper proposed a Cogtool-based interactive interface evaluation method that predicts the interactive process in terms of human’s cognitive characteristics, which significantly improves the objectivity of interface evaluation and has the advantages of economy and convenience. The Cogtool-based interactive interface evaluation method was studied in this research. (1) Interactive tasks were designed according to the main functions of the interface and Cogtool was adopted to predict the performance in completing the interactive tasks. Various data were collected such as the time required, action sequence, and the times of page turn. (2) A vague set evaluation system was established, and the vague value of each interface design scheme was calculated. The TOPSIS method was adopted to rank the multiple interfaces. (3) Taking three automotive audio and video navigator interfaces as example, the feasibility of the Cogtool-based interactive interface evaluation method was verified, and suggestions on the optimization of layout and structural logic were proposed in the end.
