目的 以提升听障患者生活质量为目标，尝试在增强现实交互技术的帮助下以视觉上的扩展来弥补听障缺陷，并将数字建构产品作为最终物态进行呈现。方法 以数字建构的设计方法与增强现实的技术路径为指导，针对听障患者的具体需求展开探讨，研究了数字建构下增强现实交互听障系统深度开发的可能性，为后续设计提供了思路并最终得出方案。结论 随着计算机硬件计算速度的提升，计算机处理多任务的能力更为出色，增强现实交互技术得以通过连接设备，将虚拟世界投射到现实世界中。利用此特性，以数字建构的方式集成智能设备，有助于弥补人体的多种生理缺陷，为残障人士建立与外界正常沟通的介质，具有重要的理论与实践意义。

The work aims to improve the life quality of people with hearing impairment by attempting to compensate for the hearing impairment with the help of augmented reality interaction technology and visually expanding and presenting digitally constructed products as the final object. With the design method of digital construction and the technology path of augmented reality as a guide, the possibility of developing an augmented reality interactive system for the hearing impaired with the help of digital construction was explored, ideas for the subsequent design were provided and a solution was finally obtained. With the increase in computing speed of computer hardware and the ability of computers to handle multitasking and workflow, augmented reality interaction technology allows for the projection of virtual worlds into the real world through connected devices. Using this feature to integrate smart devices in a digitally constructed way is of great theoretical and practical importance, as it can help to compensate for the many physiological deficiencies of the human body and establish a medium for normal communication with the outside world for people with disabilities.
