VI. CONCLUSION
LNS is a microblog service which shares information in a
small group and operates on a personal cloud service. That
group is able to work with objects such as home appliances
and healthcare devices. In addition to sending messages from
the devices to LNS, an icon representing the device is sent
each time. LNS is able to work with submissions from
various devices via user authentication without registering
the device beforehand. Using a message embedded in the
EXIF data of the icon sent, messages can be transmitted via
FTP and other protocols. Using the medium of SD cards
equipped with wireless LAN capability, implementation on
devices is easier and they become able to work with LNS.
We have created a smartphone application and users can
view LNS information in a unified location using a
microblog service such as Twitter. We have received
extremely favorable subjective evaluations of our system
from users. We are currently designing and implementing a
system to serve as an operational model that would enable
home nursing information to be shared between families and
home helpers. In this implementation, service reports from
home helpers to care managers are computerized and sent to
LNS. By then forwarding the information posted to LNS to
Facebook, we believe that it would be possible to share
information smoothly with family, doctors, and others.
