Design Of Multi-Function Wheelchairs Based On Human-Machine Interaction

At present,China has gradually entered an aging society.At the same time,due to the frequent occurrence of diseases and accidents,patients with lower extremity injuries and limited functions are still common.Therefore,wheelchairs are facing increasing demands;and with the improvement of the level of science and technology With the popularization of smart products,the demand for wheelchair functions and intelligence has also increased.However,most wheelchairs currently on the market have simple functions,poor human-computer interaction,and intelligent systems are still less used in wheelchairs.There are still great difficulties for users to fully realize their own lives.Therefore,based on the theory of human-computer interaction,this dissertation researches intelligent wheelchairs and designs intelligent wheelchairs that integrate obstacle avoidance,automatic obstacle avoidance,standing deformation,assistive rehabilitation and other functions to meet the needs of special populations,and for intelligent wheelchairs.The appearance and the man-machine interface were innovatively designed and the design scheme was given.The test results show that the wheelchair has strong human-computer interaction compared with similar products and can help the user complete more actions independently,and has a great market application prospect.Firstly,this paper researches and researches the status quo of intelligent wheelchairs both at home and abroad,and outlines the definition,development,elements,research objectives,processes and methods of human-computer interaction theory.At the same time,it defines intelligent wheelchairs and discusses human-computers.Application of Interaction Theory in Intelligent Wheelchairs.Second,through market research,we analyze competitive products,intelligent wheelchair functions,and intelligent wheelchair technologies;at the same time,through user research,we analyze the needs of users in the four aspects of physiology,psychology,society,and aesthetics,and perform role model settings.Target the target users and functions of the smart wheelchair.Again,on the basis of market research and user research,the design principles of the intelligent wheelchair modeling and the interactive interface are proposed.The modeling principles include security,comfort and operability;the principles of the interactive interface include conciseness,Direct and easy to understand.Finally,the design practice of intelligent wheelchair based on human-computer interaction was carried out.The design was made from four aspects:function,shape,color and interactive interface,and experimental tests and usability assessments were conducted.The realization of the plan has great significance for reducing the labor intensity of the medical staff and improving the quality of life of the patient,and has reference and reference value for the development of similar products.
