Lifelog visualization for elderly health care in Informationally Structured Space

As the number of elderly people living alone increases, more caregivers are required to support the aging society. Such elderly people have little chances to communicate with other people and are likely to be socially isolated. The monitoring system is one of possible solutions to confirm the safety of elderly people. Sensor network or portable sensing devices can be applied to such monitoring systems. However, basically, such systems are unilateral systems to just observe human states. It is important for elderly people and their families to create opportunities for communicating with each other. Visualization based on lifelogging is one of the important and effective techniques implored to understand and share personal preference and lifestyle. If the elderly's family members can share their hobbies, diversions and lifestyle, then they can easily select common topics to discuss and ensue communication. In this study, we develop a visualization system to represent personal relation between elderly people and their family members based on their daily activities. Moreover, this paper proposes a method of topological visualization based on the spring-mass-damper system (Spring Model).
