摘　　要：由于各种移动智能设备特征各异、操作方式多样、使用环境复杂、用户类型众多等诸多因素,使得移动应用的易用性评估问题非常突出。文章试图探索基于用户操作轨迹的移动应用易用性评估方法。该方法通过构造用户操作轨迹状态机模型,比较分析用户真实操作轨迹模型与预期的标准操作轨迹模型之间区别,评估和发现可能的易用性问题。With the fast evolution in the development of applications for mobile smart devices, the study and ade-quacy of usability evaluation methodologies in this context is becoming an increasingly demand. Traditional laborato-ry based usability testing is often tedious, expensive, and does not reflect real use cases. In this paper, a novel re-mote usability evaluation approach has been proposed for mobile applications. This approach automatically collects user interface events as the user interacts with the applications, and then models user operation tracks using state machine. By analyzing and comparing real user operation state machines with expert operation state machine, we e-valuate mobile applications with some proposed usability metrics, and find usability faults.
