使用移动的设备的应用程序的设计需要与桌面应用程序不同的质量评估。在必须考虑的许多方面中，一个重要的标准是用户完成任务所需的平均时间。对于与鼠标、键盘或触摸屏的交互，存在预测交互时间的模型，如费茨定律或按键水平模型（KLM）。本文展示了这些模型的相似之处，先进的互动与移动的手机针对普适服务，包括近场通信以及内置的摄像头和传感器。应用程序可以根据用户性能时间进行评估，而无需在手机上运行原型。为了实现这一点，我们扩展了已知的KLM确定移动的手机的基本交互元素，并从几个用户测试专家用户性能的估计。
The design of applications using mobile devices needs a different quality assessment than those known for desktop applications. Of the many aspects that have to be taken into account, one important criterion is the average time users need to complete a task. For interactions with the mouse, keyboard or touch screens, there exist models that predict interaction times like Fitts' law or the Keystroke-Level Model (KLM). This paper shows parallels to these models for advanced interactions with mobile phones targeted at pervasive services, including near field communication as well as built-in cameras and sensors. Applications can be evaluated with respect to user performance time without having a prototype running on the phone. To accomplish that, we extend the known KLM by identifying basic interaction elements for mobile phones and give estimates for expert user performance derived from several user tests.
