Study of Collecting User Operation Log in Ordinary Environments and Comparison with Controlled Experiment Data

在订购时，以描述观察条件的影响，这是受控实验，我们开发的方法是收集用户GUI操作日志在正常环境中，这是学生的计算机室。我们收集了161名学生的操作日志，为几个月。根据基本图形用户界面操作时间的比较，我们将显示以下的结果。在受控的实验中，物体倾向于用他们的手腕和上部手臂移动老鼠，并停止他们的操作，如他们选择较大的目标，如窗口。在受控实验中的操作时间是一个短的时间，因为物体集中在任务上。在学生的计算机室，学生之间的键击间隔分布很小，性格也很小。Furthermore，我们分析常规环境数据来确定鼠标指针错误的原因。我们发现了两种错误类型，一种是由于一个按钮操作的侧面影响而受到非故意的鼠标运动影响，另一种是一个按钮操作和一个移动操作之间的同步错误。从这个分析中，我们建立了一个算法来确定用户想要点，并通过使用我们的算法来确认减少点错误。

In order to characterize the influences of observed conditions, such as controlled experiments, we develop the way to collect user GUI operation log in ordinary environment, such as students' computer room. We gather 161 students' operation log for S months. By comparing about the basic GUI operation time, we obtain the results shown below.・ In controlled experiment, objects tend to move mice by their wrists and upper arms and stop their operations as fast as possible when they select large targets, such as a window.・ The operation time in the controlled experiment is shorter because objects concentrate on their tasks. At the students' computer room, the distribution of key-stroke intervals between students is small and characteristic.Furthermore, we analyze the ordinary environment data to inquire the cause of mouse pointing errors. We find two types of error, one is an unintentional mouse motion affected by the side effect of a button operation and the other is a synchronization error between a button operation and a move operation. From that analysis, we make an algorithm to guess the coordinates that the user want to point and confirm to reduce pointing errors by using our algorithm.
