At home, the bathroom is a place where it is necessary to use every day, it is easy to slip. Care for the elders with careful attention. The bathroom is also a place of high privacy. Therefore, the bathroom system may be the entire family system, the hardest place to do it: at home. The bathroom is a place that needs to be used every day. It is easy to slippery. Care for the elders requires careful attention. The bathroom is also a place of high privacy. Therefore, the bathroom system may be the most difficult place for the whole family system:
Their own family, taking care of themselves. The bathroom is a place of high privacy. The elders, in such an environment, are also the most dangerous place. Therefore, the bathroom door is closed and it needs a good way to detect people’s safety and reduce false alarms. , Reduce the risk of environmental use.
