手机三维菜单绩效预测模型

菜单是手机界面的重要交互部件，手机功能增加所带来的菜单规模增大与手机小屏幕形成日益突出的矛盾.三维界面技术可以提高界面信息容量，因此，在手机上引入三维菜单概念是一个值得研究的课题.相应地，需要解决手机三维菜单用户操作绩效的评估问题.模型预测评估法能使研究人员和设计人员快速和以较低成本对用户界面进行评估.因此，基于Fitts定律和Hick-Hyman定律，建立了预测评估手机三维菜单操作绩效的定量模型.通过实验检验了模型的有效性，并将其与相关模型进行了对比分析.实验结果表明，实验得到的数据与该模型预测数据吻合较好，并且与相关模型相比该模型预测数据与实验数据的相关度最高.

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.
