使用红外线传感器进行眼球运动追踪

Arduino IDE

关于这个项目

我使用红外传感器来感知眼球运动并控制 LED。

NeoPixel LED 眼球

使用 NeoPixel LED 胶带。 LED是68个单位。

LED 用双面胶带固定在碗上，并按以下顺序接线。

眼动追踪

原理图

传感器

我使用了两个传感器 QTR - 1A 进行眼动追踪。 QTR - 1A 放置在塑料片上，距离约为眼睛的宽度。

传感器部分和微控制器部分分别用夹子固定在眼镜上。

Arduino代码

当虹膜接近一个传感器时，反射光减少，传感器值增加。相反，当虹膜移开时，反射光增加，光反射器的传感器值减小。

LED眼球瞳孔的左右运动感知一个传感器值的增减并加以控制。

眨眼时，两个传感器值都下降，所以如果两个传感器值同时下降，LED眼球的眼皮就会下降。
