Arrangements of the congregate meal site based on elderly interactive behavior

Because of their familiarity with various sites and members, elderly people behave differently in the dining hall, including when they choose their seats. More than half elderly tend to choose the same seats, and prefer to use personal items to occupy the seats. They also move the chairs or even communicate with others to make sure the people they know sit beside them. However, for some elderly people, the restrictions of the seats decrease the quality of interaction with others.
