要处理的事件侦听器 headtrackr.js

Question

我希望能够使用 headtrackr.js

通过头部移动来滚动页面

我已将代码实现到基本 html 页面上。

<html>
<head>
<title>Test</title>
  <script src="headtrackr.js"></script>

</head>
<body>
<canvas id="inputCanvas" width="320" height="240" style="display:none"></canvas>
<video id="inputVideo" autoplay loop></video>
<script type="text/javascript">
  var videoInput = document.getElementById('inputVideo');
  var canvasInput = document.getElementById('inputCanvas');
  var htracker = new headtrackr.Tracker();
  htracker.init(videoInput, canvasInput);
  htracker.start();
</script>
<p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. </p>
</body>
</html>

以上内容启用了 SSL - 出现了视频。面部被检测到。但是文档没有滚动。

我还需要其他东西吗？像听众一样阅读 headtrackr 读数？我在 github 或 http://www.digitoffee.com/video/scroll-a-document-by-just-moving-your-head/428/

的文档中找不到这个

也许可以尝试添加此事件侦听器来更改您想要执行的任何操作？

document.addEventListener('headtrackingEvent', function(e) {
 window.scrollTo( e.x, e.y );
}
