Research On The Experience Design Of The Knee Joint CPM Machine Based On Embodied Design Theory

Under the background of the overall development of China’s overall economy and the continuous improvement of people’s healthy living standards,people’s demands and expectations for health are also increasing.Under this circumstance,for some patients with limited physical function and limited mobility,rehabilitation therapy is undoubtedly an effective treatment,and its efficacy is widely recognized by patients.However,due to the late start of the domestic rehabilitation equipment enterprises,they only focus on technology research and development,and lack the care for the rehabilitation experience of patients during use.Although there are many types,the function is simple,the process is rough,and it is not humanized enough to meet the growing psychological and physiological needs of consumers.Nowadays,in the design innovation of product experience,research on the user’s physical behavior has become the core essence.The theory of embodied cognition is different from the traditional first-generation cognitive psychology theory.Its core is the theory of physical and mental integration,emphasizing the participation of the body in the process of individual cognition.The design intervention of behavior to improve the experience of the whole process provides new theoretical support.In order to optimize the user experience in rehabilitation training,meet the emotional needs of patients,and accelerate the rehabilitation process,this paper starts from the user experience process,based on the theory of embodied cognition,explores new research on knee function recovery device and all-round experience design.Strategy and new ideas have important theoretical significance and application value.This paper adopts the research methods of user research,physiological signal acquisition and analytic hierarchy analysis,firstly on the basis of analyzing the background and development of the cognitive theory of the body,combined with the experience of the traditional knee function recovery device to experience the body experience.Based on this analysis and research,we constructed and verified four product experience modes based on the cognition,namely “container schema”,“balance schema”,“measure schema” and “forward-backward schema”;Based on the association model,combined with physiological signal acquisition and experience emotion analysis,the four experience modes were proposed and the potential needs of users were studied.Through the use of tomographic analysis method to evaluate and analyze the user’s needs,based on this,a product experience design strategy based on personal cognition is proposed,and how to apply the four product experience models based on personal cognition to the product experience.In the end of the design,in order to verify the feasibility of the design strategy of the knee function recovery device based on the body cognition proposed in this paper,the paper applies this design strategy to carry out the embodied-embedded design practice,which proves that this paper proposes the design strategy based on the theory of the body is practical.The application of the embodied cognition to the experience design of the knee function recovery device can provide some support and reference for the theoretical research in the field of cognitive application,expand the design concept and application scope of the body design,and design for the product experience.It provides a new perspective,and the work of this paper has practical guiding significance for design practice activities.
