Usability Research Of Mixed Reality System For Museum Guide Tour

Museums are cultural institutions with the main purpose of collection,research,display,and education in contemporary society.The effectiveness of exhibitions depends largely on whether they can give the audience a high-quality visiting experience.A museum's information navigation system is the primary technical tool to guide users to generate cognitive processes.Presently,the navigation systems in most history museums in China share shortcomings such as one-dimensional content,disconnect between content and exhibits,and poor guidance.Here we analyze the existing problems in such navigation systems,using quantitative analysis and interdisciplinary research methods to analyze and summarize the core requirements of target users.During the investigation,the application environment and product use cases of the navigation system were analyzed,and the usability and application advantages of mixed reality technology in a museum navigation system were summarized.Firstly,mixed reality technology has the interactive characteristics of understanding and extending human natural behavior,constructing real spatial relationships between virtual and physical objects,and realizing interactive behavior that conforms to social behavior and psychological paradigm.Mixed reality technology can integrate virtual information content with actual exhibition space and the user's interaction behavior in order to achieve the user's core requirements for the navigation system.Through analysis of the technical principles and interactive characteristics of mixed reality technology,we propose specific design principles and design models of a museum navigation system based on mixed reality technology.We took into consideration the formation of psychological representation and the rational use of situation effects in the cognitive process,and incorporated these concepts into our design process to help users deepen their understanding and memory of the content of navigation through knowledge transfer and concept networks.Secondly,in the experimental analysis of the core functions in a mixed reality navigation system,we used the quantitative method of usability measurement to obtain user experience feedback on the core functions.Using research methods of formative usability measurement,we conducted data collection and analysis on sample size,user goals,and user performance measures during use.Based on the data collected,we attempt to identify specific factors that influence the usability of mixed reality technology in user behavior and visual guidance.Our experiment found that positioning accuracy,feedback of recognition progress,and depth of integration between the virtual environment and the physical space all affect the system's usability and experience to a certain extent.Based on analysis of results in conjunction with user feedback,we further explored the product design requirements of a mixed reality navigation system.The design principles for such a system primarily focus on the system'score functional architecture,human-computer interaction methods and processes,interface presentation principles,and information content architecture.The design experiment produced the spatial positioning mechanism,information prompt mechanism and visual guidance mechanism of the navigation system for the usability experiment results.Design principles that meet core user requirements can help the navigation system fully reflect the advantages of mixed reality technology in specific usage scenarios,and enhance the usability and experience of the museum navigation system.Finally,adhering to the above design principles,we designed and implemented a mixed reality museum navigation system based on user behavior guidance function,which was field tested at the ZiyuJinsha exhibition at the Wuxi Museum.Following the field test,we used AHP to quantitatively evaluate the usability,interface quality and information quality of the navigation system.This navigation system is designed mainly for visitors to museums,includes implementations for back-end museum information management and front-end guide services,and provides users with an improved museum experience.
