“…To obtain an optimal design is a crucial problem in interaction design, because it can make an interactive product more competitive.User centered design (UCD), which involves end users throughout the entire design phase, has typically been applied for interaction design. However, adopting UCD to derive the optimal product entails limitations such as high cost and time consuming (Zhou, Heesom, & Georgakis, 2007). To effectively derive the optimal design for interactive products, Guo, Liu, Cao, Liu, and Li (2016) proposed a method that used back-propagation neural network to build quantitative model between design patterns and performance characteristics and then used a genetic algorithm to search for an optimal design.…”
