构建一个通过物体工作的手势传感器
几年前，我创建了一个支持手势交互的嵌入式项目，允许用户通过向左或向右滑动来翻页。然而，一直困扰我的一个问题是，传统的手势传感器依赖于光信号，这意味着它们必须保持畅通无阻。这需要切一个洞来暴露传感器，这看起来并不美观。所以，我想知道：有没有一种方法可以隐藏手势传感器，同时保持良好的性能?这是一个我一直无法解决的挑战。
现在，当我开始创建另一个有趣的互动项目时，我开始再次寻找符合我要求的手势传感器。我不仅找到了一个，而且它也更强大——提供更高的灵敏度、更高的精度，甚至可以精确地跟踪手部运动的3D空间。有了这个，我可以在我的项目中加入更多创造性的互动。
最后，我成功地集成了一个可以通过实体物体检测运动的手势传感器。它使用I2C协议，使其相对容易与微控制器接口。复杂的算法预先配置并存储在传感器的固件中，允许微控制器通过简单的I2C通信检测手势。
