CSR: Small: Collaborative Research: Smartphone Enabled Social and Physical Compass System (SENSCOPS)

智能手机配备了强大的嵌入式传感器（如加速度计、GPS、麦克风等），可用于监测人类行为的多个维度，包括身体、心理和健康的社会行为。特别是，移动设备的这种增强功能使人们能够更好地管理自己的健康。现有的移动健康应用程序主要依赖于手动数据输入，这可能不足以满足某些人群，例如老年人和患有情绪行为障碍（EBD）的学生。本项目旨在建立一个多模态传感系统，对用户进行持续有效的监测。使用移动电话和可穿戴传感器的活动。我们的系统分析和关联不同的传感器流来推断某些行为以及可能触发这些行为的环境因素。此外，我们的系统提供非侵入式同伴辅助定位技术，允许护理人员跟踪被监控用户的下落。我们还开发了有效的方案来推断更高层的信息，例如被监测个体的活动水平；被监控用户之间的社会关系。此外，从我们系统中启用移动电话的社交网络中提取的社区不仅可以启用移动医疗保健系统，还可以用于保护系统的某些组件（例如，应对克隆攻击）。我们的系统可以监测用户的心理、认知和身体健康状况，并且可以通过提高教师和护理人员的生产力来潜在地降低特殊需要教育的成本。

Smartphones equipped with powerful embedded sensors (e.g. accelerometers, GPS, microphones, etc.) can be used to monitor multiple dimensions of human behaviors including physical, mental, and social behaviors of wellbeing. In particular, such enhanced capabilities in mobile devices enable people to better manage their health. Existing mobile health applications mostly rely on manual data entry which may not be sufficient for certain population e.g. seniors and students with emotional behavioral disorders (EBD). This project aims to build a multimodal sensing system which provides continuous and efficient monitoring of users? activities using mobile phones and wearable sensors. Our system analyzes and correlates different sensor streams to infer certain behaviors as well as possible environmental factors that may trigger such behaviors. Furthermore, our system provides non-intrusive peer assisted localization technique that allows caregivers to track the whereabouts of monitored users. We also develop efficient schemes to infer higher layer information e.g. activity levels of monitored individuals; social relationships among monitored users. Additionally, the communities extracted from a mobile phone enabled social network in our system not only enable mobile healthcare systems but can also be exploited for securing certain components of the system (e.g., coping with clone attacks). Our system allows users to be monitored for their mental, cognitive, and physical well-being and can potentially reduce the cost for special need education as a result of increasing the productivity of teachers and caregivers.
