Multi-objective Optimization Design of Product Operation Interface Element Layout

The work aims to find the optimal layout of interface elements in the method of multi-objective optimization design, in order to boost the operating comfort and human-computer interaction efficiency of the interface, in view of the randomness and uncertainty in the operation interface layout design of the products. Four basic principles of interface layout were determined based on the criteria of ergonomics and aesthetics evaluation of interface layout, including gradation, correlation, conciseness and comfort. A multi-objective optimization mathematical model was established for the interface element layout according to the proposed principles. Based on this model, the improved genetic algorithm was applied to establish the multi-objective optimization method of interface element layout based on the genetic algorithm. The basic principles of layout design of product operation interface were presented to propose a multi-objective optimization method and process of element layout of product operation interface based on the genetic algorithm. The proposed layout principles and optimization method can better assist the designers in obtaining the layout solutions in line with the design requirements. The example results indicate the rationality of the theoretical model and the effectiveness of genetic algorithm in solving multi-objective optimization problem of interface element layout.
