Study of users' kansei on commercial aircraft cockpit interior design

Kansei engineering (KE) is applied to study the relationship between commercial aircraft cockpit interior design and users' kansei. Through studying the procedure of KE and the characteristics of cockpit interior design, the process of KE in the field of commercial aircraft cockpit interior is introduced, which contains four steps: selection of picture samples, study of users' kansei, construction of design element index and construction of the association model. Semantic differential method is used to obtain users' kansei values. Morphological analysis is used to study the design elements. The relationship model between users' feelings and design elements is found based on back propagation artificial neural. The example of cockpit T-shape area shows the result of the predicted kansei values and the users' subjective kansei values agreed. This proves the relationship model can be used to predict the kansei evaluation of the cockpit interior design, and KE can be used in the design of cockpit interior.
