通过对老年人出行产品系统设计，来实现老人对城市生活环境的整体适应，已经成为设计领域重要的研究课题. 该设计是建立在对老年人体生理学、心理学、人机工程学和社会学等学科的研究基础上，多学科交叉运用的过程. 因此，应从对老人实际生活状态的研究出发，结合老人自身的人群特征与个体差异，运用科学的方法和技术，坚持直观适应、渐进适应、容错适应、补偿适应、安全适应等基本设计原则，秉持“由人及物，由物成域，域可适人”的整体思维进行设计，进而实现老人对现代城市出行环境的有效适应. 

Improving the adaptability of elders in urban living environment via design of outdoor products is an important research topic in the design field. The design of outdoor products is based on multidisciplinary research, such as the ergonomics, sociology, physiology and psychology research of elders. Therefore, the adaptable design should base on the real life state of elders, combining with the considerations of the individual difference, then improve the adaptability of elders in modern city using scientific method. 
