来自YouTube / Bilibili的虚拟按钮UI隐喻教程已经流行了好几年了。在网站中，虚拟按钮是AR交互技术的一个领域，经常被技术爱好者讨论和发布。根据以下内容和点赞，AR交互教程比YouTube用户对AR技术的迭代开发更受欢迎。

我选择了Unity, Vuforia和Cinema 4D来创建AR图书的交互系统。Unity提供了更大的可定制性和处理复杂项目的能力，使其成为需要深度交互和复杂场景的AR应用程序的理想选择。此外，Vuforia插件为Unity在AR开发中提供了更多的技术优势，例如高级跟踪和动画控制。同时，Unity正在优化跨平台兼容性。例如Cinema4D，用于建模和动画，可以导出FBX格式，与Unity有很好的兼容性，适合AR内容创作。所有这些都是促使我最终决定使用Unity的原因。

设计文件的实践包括以下步骤：

第一步：手的AR跟踪将是一个挑战，比如双摄像头，以及与之交互的速度。

第二步：学习Unity和Vuforia。水墨画中站着两位美女。然而，没有运动动画。

第三步：学习Unity和Vuforia在设备上的设置：Unity→Vuforia→XCode→iPad iOS。同时展出两幅水墨画和三名少女。它与雪效果配合得很好。但是仍然没有运动的动画。

第四步：动画作品。这是一个粗糙的视觉场景：物理环境中的卷轴和虚拟空间中的一系列美女。

第五步：当我们的手经过虚拟按钮时，播放行走动画。

第六步：用户可以触摸水墨画中的关键线索，看到虚拟人物如何移动和变化。

第七步：在AR iOS应用程序的虚拟空间中进行手部交互。读者触摸到画中的绿色玉石，玉石所象征的虚拟人物开始移动。

The Virtual Button UI Metaphors tutorials from YouTube / Bilibili have been popular for a few years now. On websites, virtual buttons are one area of AR interaction technology that is frequently discussed and posted by technology enthusiasts. According to the following and thumbs-up, the AR interaction tutorials are more popular than iterative development for AR tech by the YouTubers.

I selected Unity, Vuforia, and Cinema4D to create an interaction system for AR Books. Unity offers greater customizability and the ability to handle complex projects, making it ideal for AR applications that require deep interaction and complex scenes. Additionally, the Vuforia plugin gives Unity more technical advantages in AR development, such as advanced tracking and animation control. Meanwhile, Unity is optimizing cross-platform compatibility. For instance, Cinema4D, which is used for modeling and animation, can export in FBX format and has good compatibility with Unity, making it suitable for AR content creation. All the above are the reasons that led me to finally decide on Unity.

Through scrolling, the pages were transformed into a stage, which was a new way to interact with the AR Book. Practice with the design document involves the following steps:

Step 1: AR tracking of the hand will be a challenge, such as dual cameras, and the speed at which it is interacted with.

Step 2: Learning Unity and Vuforia. Two beauties are standing in the ink painting.    However, there are no movement animations.

Step 3: Learning Unity and Vuforia sets up on the devices: Unity → Vuforia → Xcode → iPad iOS. There are two ink painting images, and three girls are displayed at the same time. It works well with the snow effect. But there are still no animations for movement.

Step 4: Animation works. This is a rough visual scene: A scroll in a physical environment and a series of beauties in a virtual space.

Step 5: When our hands pass over the virtual button, play a walking animation.

Step 6: Users can touch the key clues in the ink painting and see how the virtual character moves and changes.

Step 7: Hand interaction in the virtual space of the AR iOS application. A reader touches the green jade in the painting, and the virtual character symbolized by the jade begins to move.
