挥挥手就能操控PPT?理想照进现实,谁接入这款技能,谁就能隔空操作!!

上课不用翻页笔了！挥挥手就能操控 PPT

AR进课堂的零成本方案：摄像头识别手势，隔空翻页、激光笔、黑屏。纯本地运行，不联网、零积分。

老师的小痛点

  • 翻页笔没电 / 忘带，只能跑回讲台点鼠标
  • 想走到学生中间讲课，手却够不着电脑
  • 公开课想“炫”一下，又不想多买设备

一个技能包就解决

yrns-air-ppt：用普通摄像头识别手势，直接操纵PowerPoint/WPS 课件。底层是 MediaPipe 手部识别+OpenCV，全程在您电脑上跑，画面不上传、不消耗任何积分。

五个手势，全部隔空完成

  • ☝️ 伸食指 → 空中指针，指哪打哪
  • 🤏 捏合 → 单击
  • 🖐 张掌挥一下 → 上一页 / 下一页
  • ✌️ V 字停 1 秒 → 开 / 关激光笔
  • ✊ 握拳停 1 秒 → 黑屏 / 恢复

三步上手

  • 装一次依赖（约 100MB）
  • 运行脚本，弹出预览窗
  • PPT 按 F5 放映，对着摄像头做手势

适合谁

公开课、微课录制、培训讲座、家长会——只要边走边讲，它就有用。
