手持设备三维菜单绩效评估

为了使研究人员能够快速、有效对手持设备的三维菜单设计进行评估，基于Fitts’定律和Hick-Hyman定律，提出了一个预测手持设备三维菜单操作绩效的模型，并用实验验证了该模型的有效性。实验分为两个阶段，第一阶段的实验是为了计算模型中的系数a₁，b₁，a₂，b₂的值，并将其用于实验第二阶段的数据分析；第二阶段的实验是为了验证模型的有效性。并结合AIC（Akaike Information Criterion）准则对该模型与其他模型进行了对比分析。实验结果表明，该模型预测得到的用户操作绩效数据与实验测试得到的绩效数据非常接近（二者相关性为0.914 5），且通过AIC准则分析表明，该模型最优。因此，该模型是有效的。

Evaluation of 3D menu performance on mobile phone

A predictive model of 3D menu performance on mobile phone based on Fitts＇ Law and Hick-Hyman Law is pro- posed and validated by experiments, so that researchers can evaluate the design of 3D menu on mobile phones in a more ef- ficient and more effective way.The experiment is divided into two stages.In stage one, the value of coefficients aj, ＆, 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 mod- el is validated.Besides,according to Akaike Information Criterion（AIC）,the model is analyzed contrastively with other models. The results show user performance data predicted by the model is very close to the data from user testing（the corre- lation coefficient is 0.914 5）.And through AIC analysis,it shows that the model is the most optimal one.Therefore,the model is valid.
