16 A Predictive Model of 3D Menu Performance on Mobile Phone Based on Fitts' Law and Hick-Hyman Law

A predictive model of 3D menu performance on mobile phone based on Fitts' Law and Hick-Hyman Law is proposed and validated by experiments, so that researchers can evaluate the design of 3D menu on mobile phones in a more efficient and more effective way. The experiment is divided into two stages. In stage one, the value of coefficients a1, b1, a2 and b2 in the model is calculated and applied in the data analysis process in stage two. In stage two, the effectiveness of the model is validated. The results show user performance data predicted by the model is very close to the data from user testing (the correlation coefficient is 0.914 5). Therefore, the model is valid.
