Cloud Middleware （ 2/5 ）

Cloud Database

Live E! Data Transfer Platform or sensor data

Cloud Middleware

• Live E! protocol–Developed by The University of Tokyo

–IEEE 1888

• API for cloud data center

• Design a highly reliable middleware to access cloud databases.

• The high flexibility feature of cloud facilitates dynamic adjustment of services and the receiving of useful information.

Caring Record

Elderly Information

• Provide current information– body measurement, activity of daily living

(ADL), and doctor prescription– To elderly and their families, and medical

institutes.

• Support Caring record for medical staff to better understand elderly people from long-term health status.

• Explore potential applicative possibility through caring records analysis– Data mining related applications

• Enhance social involvement of elderly people through Facebook application–Automatic sentence analysis and generation
