【摘要】：随着增强现实技术的发展与智能手机的普及,基于移动平台的增强现实应用展现出了巨大的发展前景,对于移动增强现实的研究也越来越广泛。增强现实的发展长期以来以技术为驱动,用户对于增强现实的知识和体验经历普遍比较匮乏,难以较清晰的表达对于移动增强现实应用的交互偏好和期望需求,这使得以用户为中心的设计方法在移动增强现实应用的设计实践上出现了困难。本文以构建超市场景下的移动增强现实购物应用为设计任务,采取了基于用户心智模型的用户体验设计方法。首先,本文分析研究了基于心智模型的用户体验设计方法。用户心智模型分为宏观与微观两种形式,反映着用户的需求、认知结构和交互偏好。本文建立起用户心智模型与用户体验设计任务之间的映射关系,对用户心智模型进行构建与分析,作为用户体验设计中信息架构、物理交互、界面与视觉呈现三方面内容的设计参考。然后,本文通过用户观察、参与式设计等实验的方法对用户进行任务分析和需求收集,进而确定产品功能需求,进行了快速的原型开发。通过在整个产品设计过程中进行反复的用户测试与迭代开发,使应用不断趋近用户的预期用户体验。同时,结合移动增强现实设备与交互的特点,在界面形态与物理交互等方面对移动增强现实应用的设计空间进行探索,实现了混合式的界面形态及其交互操作的设计,在丰富用户的交互方式的同时改善了用户的交互体验。应用原型的可用性测试表明,本文提出的应用原型丰富了用户在超市购物场景下的交互体验,有助于用户对于信息的感知,用户满意度较好。本文对于移动增强现实应用的设计和开发具有参考意义,具有其学术价值和应用前景。
[Abstract]:With the development of augmented reality technology and the popularization of smart phone, the application of augmented reality based on mobile platform presents a great development prospect. The research on mobile augmented reality has become more and more extensive. The development of augmented reality has been technology-driven for a long time, and users' knowledge and experience of augmented reality are generally scarce. It is difficult to express clearly the interaction preferences and expectations for mobile augmented reality applications. This makes the user-centered design method difficult in the design practice of mobile augmented reality application. The user experience design method based on the user mental model is adopted. Firstly, this paper analyzes and studies the user experience design method based on the mental model. The user mental model is divided into macro and micro forms, which reflect the needs of the user. Cognitive structure and interaction preference. This paper establishes the mapping relationship between user mental model and user experience design task, constructs and analyzes user mental model as information architecture and physical interaction in user experience design. Design reference of interface and visual presentation. Then, through user observation, participatory design and other experimental methods to the user task analysis and requirements collection, and then determine the functional requirements of the product. Through repeated user testing and iterative development in the whole product design process, the application can continuously approach the user's expected user experience. At the same time, combined with the characteristics of mobile augmented reality device and interaction, The design space of mobile augmented reality application is explored in the aspects of interface form and physical interaction, and the design of hybrid interface form and its interactive operation is realized. The usability test of the application prototype shows that the application prototype enriches the interactive experience of the user in the supermarket shopping scene. This paper is useful for the design and development of mobile augmented reality applications and has academic value and application prospect.
