【摘要】 随着信息化社会的到来,交互方式趋于多元化,加上日益加剧的老龄化社会,老年助行器研究应该高度重视用户的需求,产品易于使用是用户需求的目标之一。本文结合边缘交互理论,研究老年助行器的交互方式,实现老年助行器易用性的目标。主要研究包括以下几方面:(1)对传统边缘交互理论进行应用性拓展。在深入研究传统边缘交互理论优势与不足的基础上,进行合理化拓展。将需求分析、SEEV注意力因素、多属性决策法的新元素纳入边缘交互理论新架构的研究范畴,其中,需求分析作为产品整体设计流程的输入端,以基于SEEV因素和多属性决策法的交互设计要素所属注意力层级分配方法为桥梁,搭建起完整的边缘交互理论新架构,形成一套有效的老年助行器交互设计方法。(2)设计需求指标获取。对老年助行器所属生命周期进行分析研究,对其需求进行预测,结合老年用户相关特性,获取设计需求指标。(3)老年助行器的交互设计要素提取。通过需求-感知值-感知参数(RPP)三角映射,挖掘老年助行器交互过程中的感知参数,借助反向鱼骨图实现感知参数到设计要素的映射转变,完成老年助行器的交互设计要素的提取。(4)合理分配交互设计要素到相应的注意力层级。首先通过眼动实验分析,确定老年用户使用助行器时主要关注的交互设计要素信息,划分兴趣区域,获取交互设计要素的定量评价指标;然后以SEEV因素为导向,确定各交互设计要素与注意力影响因素之间的关联程度,提取定性评价指标;最后通过多属性决策(MADM)法,对指标数据进行综合评价,通过四象限图表示交互设计要素所属注意力层级的分配结果,建立完整的老年助行器交互设计要素合理化分配机制。(5)探索老年助行器不同注意力层级设计要素的交互设计方法。结合技术进化定律中的系统协调化、系统完整性、提高理想化水平、子系统的非均衡化发展、增加可控性定律,对不同注意力层级上的交互方式进行重新表达,提出了针对老年助行器的交互方法,将以上研究过程进行总结,提出了实现助行器易用性目标的过程模型。(6)结合本文的研究方法对老年推行式智能助行器进行应用研究,并验证该研究方法的可行性及有效性,提升了老年助行器的易用性,并在一定程度上丰富了边缘交互理的理论内涵。更多还原

【Abstract】 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.更多还原
