| As an essential attraction for cultural tourism,museums preserve and exhibit tangible and intangible heritage,educating and serving the public.In recent years digital innovation has become a vital force for change in museums.Many museums have begun to use digital technologies to guide visitors to interact actively and participate in exhibitions.Among them,augmented reality technology has embedded and interactive features that distinguish it from traditional technology and can optimize visitors’ learning experience enjoyably,bringing new opportunities for museum tourism.However,augmented reality is still a novel technology for the general public.There are still problems,such as immaturity of hardware devices and unreasonable layout of interface information,which harm visitors’ willingness to use it.In this context,this paper explores the factors influencing visitors’ willingness to use augmented reality tour products in museums from the perspective of accessibility design based on the technology acceptance model,supplementing relevant variables and extending the model with the help of accessibility theory.It proposes design strategies for augmented reality tour products in museums based on the model to help improve visitors’ willingness to use and better utilize the advantages of augmented reality technology.This paper first clarifies the definition of the museum tour and AR technology.It summarizes the application form of AR technology in museums,the design features of AR tour products and the current problems through case studies to clarify the research scope.The paper also looks for the extension direction of the technology acceptance model in the museum AR tour scenario through literature compilation and lists the previous entry points and variable designs;furthermore,through literature combing,the research related to the accessibility theory with application potential is elaborated,and the definition of the concept of accessibility and the division of accessibility dimensions in other disciplines are summarized.The accessibility theory is finally determined as the external variable and the acceptance.The final decision was to use accessibility theory as an external variable combined with the acceptance model.Based on this study,we refined and defined user motivation variables(including perceived usefulness,perceived ease of use,and perceived enjoyment),mediator variables(attitude toward use),and accessibility elements as external variables of the acceptability model in the museum AR tour scenario through desktop research,questionnaire research,and user interviews.In order to organize the many accessibility elements,a accessibility scale was prepared,and a questionnaire survey was conducted based on established research.After exploratory factor analysis and validation factor analysis,three main accessibility dimensions and their physical,intellectual,and psychological sub-dimensions were formed.A reliable accessibility scale was obtained after the deletion of questions.With the results of the previous study,a model of museum AR tour acceptance with accessibility as an external variable was proposed.The structural reliability of the hypothesized model and the validity of each path were verified by building a structural equation model.The results show that perceived usefulness,perceived ease of use,and perceived enjoyment are important motivational variables influencing users’ attitudes and,thus,their ultimate willingness to use.At the same time,physical accessibility,intellectual accessibility,and psychological accessibility are external stimulus variables that influence motivational variables.Finally,using the correspondence between accessibility dimensions and their sub-dimensions and motivational variables as a theoretical guide,we propose The design strategy of accessibility to enhance user acceptance is proposed.The results were evaluated to verify the strategy’s effectiveness derived from the acceptability model.The findings show that the design strategy effectively improves users’ willingness to use and experience,which confirms the effectiveness of the accessibility design strategy proposed in this paper. |
