为利用增强现实(augmented reality，AR)技术实现视力自查互动系统，使用前端框架、canvas 2d渲染引擎和TensorFlow.JS等技术，并设计系统架构和互动测试视力流程，设计实现模型训练页面、互动测试UI部分及对应的动画元素。通过摄像头捕获实时的人物动作，实现系统基于AR的简单互动，系统可以识别用户的表情与手势组合符合哪种预先设定组合，并做出字母方向识别正确与否的判断；通过屏显设备在真实视力测试的场景内，实现AR互动式测试视力的效果，经评估该系统在拥有良好用户体验的情况下实现准确判断。结果表明：通过探究AR技术实现视力自查互动系统，可使用户随时随地自查视力来爱护眼睛，保护视力，并取得了良好的效果。
In order to use augmented reality (AR) technology to realize vision self-examination interactive system, the front-end framework, canvas 2D rendering engine and TensorFlow. JS technology are used, and the system architecture and interactive vision test process are designed. Design and implement the model training page, interactive test UI part and corresponding animation elements. Capturing real-time character actions through a camera to realize simple interaction of the system based on AR, wherein the system can identify which preset combination the expression and gesture combination of the user conforms to, and judge whether the letter direction recognition is correct or not; Through the screen display device in the real vision test scene, the effect of AR interactive vision test is realized, and the system is evaluated to achieve accurate judgment under the condition of good user experience. The results show that through the exploration of AR technology to achieve vision self-examination interactive system, users can check their eyesight at any time and anywhere to care for their eyes and protect their eyesight, and achieve good results.
