论文摘要
如今，将不同类型的上下文信息集成到移动消息传递中，以提高表现力和意识，包括移动设备设置，位置，活动和心率。由于低识别精度，有时用户无法通过活动意识准确推断他人的状态。最近，活动识别技术已经提高了。但是，尚未研究通过改进技术的活动意识的用户行为。在这项研究中，我们设计了一种移动即时消息应用程序Actaware，该应用程序基于改进的活动识别技术（即提高的识别精度和增加活动过渡通知的添加），将活动意识整合到了活动意识。我们进行了一项现场研究，以探索用户行为，并发现活动意识使用户可以推测聊天中断，计划交流的原因，推测聊天伙伴是否离开/到达/到达，并加深对生活模式的理解。与披露其他类型的上下文信息相比，用户在Actaware披露活动信息的隐私问题更少。根据这些发现，我们为移动消息传递提供了设计建议，以更好地支持活动意识。
Nowadays, different types of context information are integrated into mobile messaging to increase expressiveness and awareness, including mobile device setting, location, activity, and heart rate. Due to low recognition accuracy, sometimes users cannot accurately infer others' status through activity awareness. Recently, activity recognition technology has advanced. However, the user behaviors of activity awareness with improved technology have not been studied. In this study, we design ActAware, a mobile instant messaging application that integrates activity awareness based on improved activity recognition technology, i.e., improved recognition accuracy and the addition of activity transition notification. We conduct a field study to explore user behaviors and found that activity awareness allows users to speculate on the reasons for chat interruption, plan communication, speculate on whether the chat partner is departing/arriving, and deepen the understanding of living patterns. Compared with disclosing other types of context information, users have fewer privacy concerns about disclosing activity information in ActAware. Based on these findings, we provide design recommendations for mobile messaging to better support activity awareness.
