Design and Research of Aging-Friendly Outdoor Seating Facilities Based on Ergonomics

China began to enter the aging society in 1999, and by 2021, it has turned to the severe aging society, which is the country with the largest number of elderly people, so the aging-friendly design has become a problem that must be considered by the Chinese society. By carrying out practical research, this thesis provides an in-depth understanding and analysis of the behavioral characteristics and needs of the elderly outdoor sitting and sitting, combines the emotional hierarchy theory to disassemble the user's needs, and applies the ergonomics content of the outdoor public seat to make a functional scale analysis to provide a solution and reference for the standardized design of the aging-friendly public seat, and improves the appearance of its local elements. The design results of this paper aim to effectively meet the needs of the elderly and improve their outdoor experience and quality of life.
