Abstract:
Constant and reliable health monitoring can help doctors provide higher quality
health care to meet the growing needs of the medical industry. The advent of
cloud computing has enabled low-cost sensor devices that can process their data
in real-time without powerful onboard hardware. Using an Android smartphone,
medical data can be collected and uploaded to a cloud server with ease. The
project described will enable many more devices to collect data and synchronize
with the cloud without the need for a separate internet connection. A
visualization of user activity level is used to demonstrate the power of
cloud-connectivity
