analyze the health status by means of data-mining technology. Finally, results
can be fed back instantly and suggestions made to the users. Meanwhile,
physicians in the community or a hospital can obtain their patient's health
information from the Internet and provide some suggestions to the patients
on daily dietary, exercise, and medication needs. If a patient's physiologi-
cal index is abnormal after testing, the health care cloud system would give
out warning information to the patient as well as send the message to their
family members and physicians.
Also, there are two main activities of users: uploading the raw data and
browsing the diagnosis results. Uploading activities are divided into two
steps: The first is to transmit physiological data, which are collected by
sensors, to the gateway through short-distance transmission by wired USB or
wireless Bluetooth means. The second is to deliver the data from the gateway
to the cloud servers through Internet protocol (IP) networks. A set-top box
(for USB) or mobile phone (for Bluetooth) plays the important role of the
gateway to relay data. In HCloud, apart from the mobile phone, a TV set is
another friendly interface for the aging population. So, with the assistance of
a set-top box, services would be delivered through a TV cable ubiquitously.
Figures 8.2a and 8.2b show a mobile phone and a top-set box as gateways for
data transmission, respectively, and Figure 8.2c is a scenario for home use.
