摘　　要：目的击键水平模型(KLM)量化了用户的操作行为,使设计师在产品上线前能够根据模型参数,快速预估产品在高效性方面的表现。KLM模型的局限性在于其模型参数的建立是以PC界面为标准,由于移动设备的交互方式和使用场景与PC设备不同,所以简单地将KLM模型迁移到移动界面的评估上来,可能会带来较大的评估误差。方法本研究在前期研究的基础上,提出了更适用于触摸显示操作设备的手持水平模型,通过实验对物理操作单元进行量化,在不同交互方式的属性间建立全面操作时间的预估关系,使其评估结果更可靠,在移动界面评估方面的应用更为广泛。结论以时钟APP中的典型操作任务为例,运用HLM模型预估及实验采集两种方式评估其高效性,验证了HLM模型的有效性。Keystroke-level model（KLM） can help designers quickly estimate the performance of their design in terms of efficiency by quantifying the operation behavior of users. However, the limitation of KLM is that it＇s establishment is based on PC interface. Due to the difference of interaction and usage scenario between mobile devices and PC devices, simply apply the KLM to user interface of mobile devices may lead to some serious evaluation error. In our study, a modified KLM, tentatively called the hand-level model（HLM）, is proposed to better apply to touchscreen-based mobile interface. HLM build a more comprehensive relationship between efficiency evaluation dimension and interaction of mobile user interface by quantifying more physical operating unit including sliding, translation, zooming and rotating than previous studies, which is more reliable and widely applicable in the evaluation of mobile interface. Finally, our study takes a typical operating task of clock APP as an example, using two ways including HLM and experiment collection method to evaluate the efficiency of the task, and the results verify the effectiveness of the HLM.
