The work aims to explore the requirements and practical strategies of interaction design in the development of urban public facility design. In order to build a good public space, urban public facilities became a major center, and to a certain extent, they were used as the epitome and image of the city to show urban comfort and beauty. Interaction design not only improved the efficiency and convenience of urban public facilities, but also enhanced users' experience and sense of participation. With the progress of science and technology and the development of society, the interaction design and urban public facility design had an increasingly high degree of integration, and their significance was also more important. Under the current background of information society, the content and characteristics of urban public facilities were linked with the current interaction design, and the design idea of interactive public facilities was put forward. Then, from the simple to the deep, from the external formal beauty to the internal humanistic care, and then to the fashion and intelligent trend brought by science and technology, the design strategy of building interactive public facilities was gradually explored. The urban public facility design from the perspective of interaction must attract enough attention, and should be completed as an important task, to maximize the social care to build a harmonious social atmosphere, bring a kind of body and mind interaction in the interaction and communication, and promote the realization of interactive public space as soon as possible with the creation of optimized public facilities and public space.
