A precise sensing method for awareness information based on task/schedule information

意识信息对沟通顺畅非常重要。然而，在分布式环境中，感知信息是不够的。我们把“忙碌”作为一种意识信息来关注。忙碌是一个人的可被打断程度，意味着他/她是否有时间与他人交流。我们考虑到人们从自己的任务中感受到了时间压力，所以我们提出了“基于时间表的忙碌”作为忙碌的量化因素之一。我们根据用户任务的截止期、任务的主观工作时间和到最近截止日期的空闲时间来定义和估计基于调度的忙碌程度，为了得到这些参数，实现了一个新的调度系统“Time Line Navi”。因此，用户很难注意到他们的日程安排超额预定。此外，用户不能明确地掌握其任务的状态，例如每个任务的进度，因为他们没有机会通过调度器系统知道这样的状态。为了解决这些问题，我们提出了一种基于空闲时间量的任务调度管理方法和一种基于任务间关系的任务管理方法，并在此基础上实现了时间线导航，并进行了实验评估。结果表明，空闲时间有利于用户的调度，任务间的关联使用户能够清晰、有效地管理任务；提出了一种音乐选择方法、中断和恢复方法以及外围信息的呈现方法，并将其原型实现为一些具有感知信息的应用。

Awareness Information is important to make a smooth communication. However, awareness information is not enough in the distributed environment. We focus on the "busyness" as a kind of awareness information. The busyness is a level of a person's interruptibility and means whether he/she has time to communicate with others or not. We consider that people feel a time pressure from their own tasks, so we proposed "schedule-based busyness" as one of the quantitative factor of busyness. We define and estimate the schedule-based busyness based on the deadline of user's tasks, subjective amount of work time for the tasks, and free time until the closest deadline.In order to get these parameters, a new scheduler system "Time Line Navi" was implemented.In general scheduler systems, tasks and schedules are managed independently though they are actually related. So it is difficult for users to notice that their scheduling is overbooked. In addition, users cannot explicitly grasp a state of their tasks, such as a progress of each task because they have no chance to know such state with the scheduler systems. In order to solve these problems, we proposed a task-and-schedule management method based on the amount of free time and a task management method based on the relationship among tasks, implemented Time Line Navi based on these methods, and evaluated experimentally. The results show that the free time is useful for the user's scheduling and the relationship among tasks is enable users to manage tasks clearly and effectively.In addition, we proposed a music selection method, interruption and resumption methods and presentation methods for peripheral information and implemented their prototypes as some applications with awareness information.
