Ubiquitous House and Unconstrained Monitoring Devices for Home Healthcare System

This paper suggests a healthcare monitoring system using unconstrained measurement devices with ubiquitous techniques. These measurement devices are developed into built-in type and sensor type. The first devices are built-in the households (bed, sofa and toilet seat) and measure the patient´s heart and respiration activity and estimate a blood pressure. The second devices are placed in a kitchen, front door and every room and detect the patient´s movements and activities. All digitized raw signals are transmitted to a main PC using Bluetooth wireless network from all ubiquitous devices and sent to hospital laboratory after an analyzing process. This paper suggest ubiquitous healthcare house (u-House) for a practical models of home healthcare system. And it can monitor the patient´s daily health condition and activity in an unconstrained manner.
