Research On The Design Of Elder's Walker Ease Of Use Based On Periphery Interaction Theory

With the advent of information society,interaction mode tends to be diversified,coupled with the increasingly aging society,research on walking AIDS for the elderly should attach great importance to the needs of users,and the ease of use of products is one of the goals of user demand.Based on the periphery interaction theory,this paper studies the interaction mode of walking AIDS for the elderly,and realizes the goal of ease of use of walking AIDS for the elderly.The main research includes the following aspects:(1)The application of traditional periphery interaction theory is extended.Based on the in-depth study of the advantages and disadvantages of the traditional periphery interaction theory,the paper makes reasonable expansion.Will demand analysis,SEEV attention factors,comprehensive evaluation method of the new elements into the periphery of the interaction theory of the new architecture research categories,among them,the demand analysis as the input of whole product design process,based on SEEV factors and comprehensive evaluation method of interaction design elements concentration level distribution method for bridge,set up the periphery of the complete interaction theory of the new architecture,forming a set of effective method of elderly walker in interaction design.(2)Design requirements index acquisition.The life cycle of walking AIDS for the elderly was analyzed and studied,and their demands were predicted,and the design requirements indexes were obtained based on the relevant characteristics of elderly users.(3)Extraction of interactive design elements for walking AIDS for the aged.Through the triangular mapping of demand--perceived value--perceived parameters,the perceived parameters in the interaction process of the elderly walker were mined,and the mapping transformation from perceived parameters to design elements was realized with the help of the reverse fishbone diagram,so as to complete the extraction of the interactive design elements of the elderly walker.(4)Allocate interaction design elements to appropriate attention levels.Firstly,through the analysis of eye movement experiment,the information of interaction design elements that elderly users mainly pay attention to when using walking AIDS is determined,the interest area is divided,and the quantitative evaluation index of interaction design elements is obtained.Then,SEEV factors were used to determine the degree of correlation between interaction design elements and attention factors,and qualitative evaluation indexes were extracted.Finally,the multi-attribute decision making(MADM)method was adopted to comprehensively evaluate the index data,and the four-quadrant diagram was used to represent the result of the allocation of attention levels of interaction design elements,so as to establish a complete rationalized allocation mechanism of interaction design elements of walking AIDS for the elderly.(5)The interactive design method of different attention levels design elements for walking AIDS for the aged is proposed.System of combining technological evolution law of harmonization,system integrity,improve the level of idealized,subsystem of equalization development,increase the control law,the different way to express the attention level of interaction,proposed in view of the elderly to help line device of interactive method,will summarize the research process,put forward to realize the process of walker device usability target model.(6)Combined with the research method in this paper,the application of the elderly push intelligent walking helper is studied,and the feasibility and effectiveness of the research method are verified,which improves the usability of the elderly walking helper and enriches the theoretical connotation of the edge interaction theory to some extent.
