Home-based elderly care model has become the most common way of providing care for the elderly at the present stage. How to meet the special emotional needs of this specific group of elderly people has become the key to improving the home-based care experience of the elderly. Therefore, exploring community entertainment services suitable for the elderly under home-based elderly care model and filling the emotional gap of the elderly are one of the ways to meet the emotional needs of the elderly. According to the analysis on the emotional needs of the elderly under home-based elderly care model, the community entertainment service design optimization plan that meets the emotional needs of the elderly is proposed. Service design thinking is used to describe the entertainment needs of the elderly under home-based elderly care model, and the questionnaire method is combined to obtain the expectations and evaluation values of entertainment services for the elderly in a certain community in Tianjin. Based on the user??s perceived value theory, the perceived utility function is calculated and the service design optimization model is established. Through the above methods, the optimization plan for the service design of community entertainment activities is established to enhance the “home-based elderly care” entertainment service experience of the elderly, and provide a new reference for the optimization design of the “home-based elderly care” service system.
