摘要: 随着信息技术的发展,尤其是移动互联网与物联网的发展,有关个人工作和生活的数据呈指数型增长。这些海量的数据中蕴含着丰富而有价值的个人信息,如何从这些数据中挖掘出有价值的信息成为当前信息领域的重要问题。针对该问题,介绍了普适计算领域新兴起的研究主题——记忆计算。记忆计算旨在通过各种带感知和计算功能的设备,比如智能手机、可穿戴设备等,实时感知和捕获用户线上线下活动的数据,分析并挖掘其内在价值,进而组织和管理有意义的记忆数据,实现基于情境的记忆数据呈现,以辅助个体记忆,支持社群交流与协作。讨论了基于移动情境感知的记忆计算的概念、特性、系统模型以及当前研究的关键技术与挑战,综述了记忆计算在生活日志、记忆提醒、往事回忆和群体记忆分享等方面的研究进展,并对其未来发展进行了展望。

关键词: 普适计算,记忆计算,情境感知,数字记忆,移动及可穿戴设备

Abstract: With the development of information and communication technology,especially the mobile Internet and the Internet of Things,the data about personal works and life grow exponentially.Since much valuable individual information is invisibly contained in these massive dataset.How to extract the valuable information from these great amount of data has become a new challenge.This paper introduced an newly emerging research topic in the pervasive computing field,memory computing.By utilizing prevalent sensor-embedded smartphones and wearable devices,memory computing collects heterogeneous online/offline data of user’s daily activities,extracts and mines inner memory data and associated contexts,manages useful data in the right manner,and renders context-aware individual memory information for helping users to recall their memories and promote their communication and cooperation.This paper presented the concept,features and the system model of memory computing,and discussed its key technologies and research challenges.We also reviewed the applications of memory computing,such as life logging,reminiscence,memory reminding and community memory sharing,and prospected the future development.
