摘　　要：随着嵌入式技术、移动计算技术和无线传感器网络技术的发展,越来越多的可移动的通信和存储设备上嵌入了传感器,比如,手机上的方位传感器、震动传感器(实际上,手机的话筒和摄像头也是传感器),以及嵌入到MP3播放器中的脉搏传感器,等等.这些移动设备上的传感器可以采集与人们的行动、社会交往等息息相关的个人信息.此外,随着成本的下降,这些具有感知功能的移动通信设备的持有量不断提高,再加上Internet中社会网络软件的广泛使用,一类新的感知应用应运而生-以人为中心的感知(People-Centric Sensing,PCS).PCS不仅是一个新的研究领域,而且具有巨大的潜在应用价值,近几年来引起了学术界和工业界的高度关注.该文介绍了PCS的概念、特征以及重要的研究问题和挑战,并概述了PCS的研究现状.With the technological development of embedded computing,mobile computing and wireless sensor networking,more and more mobile devices and storage devices have been equipped with some sensors,such as the magnetic and vibration sensors in mobile phones as well as microphone and camera,the heart pulse sensor in MP3 players,etc..Such on-device sensors can collect information closely related to human activity and interactions in societies.Additionally,as the cost of mobile devices decreases recently,they could be afforded by most people.By grouping the personal sensor data and extensive social networking software,therefore,a new application in sensing,called People-Centric Sensing（PCS）,is emerged,which,in fact,is not only a potentially new research area but also will create huge commercial benefit.So,in the past few years,PCS obtains great attention in academia and industry.This paper introduces the concept and characteristics of PCS,followed by the important research issues,challenges and the major technologies in use.
