A Prediction Model of 3D Menu Performance on Mobile Phone

Menus are key interaction components for mobile phone interface. As mobile phone functions increase, the contradiction between growing menu scale and smaller screen is getting more and more serious. 3D interface technology can extend interface information capacity. Therefore, introducing 3D menu into mobile phone is a subject worth studying, and for this, the evaluation problem of mobile phone 3D menu user performance need to be solved. Compared with empirical methods, model predicting methods can make researchers and designers evaluate the user interface quickly and at lower cost. Therefore, based on Fitts law and Hick-Hyman law, a quantitative model predicting mobile phone 3D menu performance is built and validated by experiment in this paper. There are two phases in the experiment. The goal of the first phase is to calculate coefficients of the model. They can be applied to the data analysis of the second phase experiment. The goal of the second phase is to test the validity of the model. Comparative results show that the data from experiments dovetails nicely with the data predicted by the model, and is most highly related to experiment data, compared with other relative models.
