"One Laptop per Child (OLPC) is a technology research oriented educational project aiming to provide low cost information processing equipment to children around the world with new opportunities to explore, experiment and express themselves. The project was initiated by MIT Media Lab and has recently concluded the first cycle research work that resulted to the basic configuration laptop ready to be shipped. The healthcare domain is of special relevance for this project. A WSN of vital sign sensors (including electrocardiogram, blood pressure, etc.) and mobile wireless display devices (the OLPC in our case) can be employed to monitor patient health in an outpatient environment (e.g. home or care center).This research discipline is known as phealth. A number of medical wireless portable actuators (including respirators, infusion pumps, etc.) using the information of the vital sign sensors can be employed to care a patient in an emergency hospital set-up after a disaster. The OLPC project represents a new challenge for pHealth because by nature it creates electronic communities of educated users in technologically poor or even virgin environments. Health status on the other hand, together with education, represent the two major challenges for those parts of the developing world that have found (even partial) solutions on drinkable water and nutrition. An OLPC interconnected community has the means to support a prevention initiative aiming at facilitating disease management and health status control within a larger (to the community) population, by monitoring, processing and transmitting personal, ambient and environmental parameters. Today’s pHealth systems assume a technology advanced environment. Mitigating it to the OLPC reality should take into account power consumption, network bandwidth and processing limitations. On top of that the community oriented health monitoring is a novel concept, that, we introduce it here for the first time."
