基于用户体验的下肢无源外骨骼设计优化研究

RESEARCH ON DESIGN OPTIMIZATION OF LOWER EXTREMITY PASSIVE EXOSKELETON BASED ON USER EXPERIENCE

为提升可穿戴下肢无源外骨骼的用户体验。对外骨骼用户体验影响因素进行分析,并结合研究重点及专家建议构建了用户需求层次模型。基于Kano模型设计问卷对用户需求进行调研,统计分析调研结果对需求指标进行定性定量分析。以统计分析结果为依据提出了下肢无源外骨骼优化设计策略。明确了现阶段外骨骼产品需求属性及用户体验提升的设计策略,为后续产品设计及体验评价提供实践性依据,对后续下肢外骨骼优化设计具有指导意义。

To improve the user experience of the lower extremity wearable passive exoskeleton.Factors influencing exoskeleton user experience are analyzed and a hierarchical model of user needs is constructed in combination with research priorities and expert suggestions.Based on the Kano model,the questionnaire is developed to study user needs and the survey results are statistically analyzed to perform qualitative and quantitative analysis of needs indicators.Based on the statistical analysis results,an optimal design strategy for the passive lower extremity exoskeleton was proposed.It clarified the exoskeleton product demand attribute design strategy and user experience improvement in the current stage,provided a practical basis for the subsequent product design and experience evaluation,and had a guiding significance for the subsequent optimization design of the lower extremity exoskeleton.
