FaceTouchMonitor.com

A website that monitors when you touch your face.

In addition to washing your hands often, the CDC recommends that you avoid touching your eyes, nose, and mouth with unwashed hands. This can be hard to do without a reminder.

This project uses the BodyPix project from tensorflow.js to detect hands and faces. When a hand intersects with the face it is considered a touch. Set beep alerts or get a browser notification when you do. The reminders can you train yourself to stop accidental face touching.

No information is shared externally - no images are transmitted and all ML processing is done locally in the browser.

Try it at https://facetouchmonitor.com. Read about it at https://webrtchacks.com/

It only takes seconds to try yourself.

Usage Notes (and to do list)

Browsers and Devices

  • Browser support - tensorflow.js works best on Chrome and has been tested in the new Edge and Firefox. I haven't been able to make it work with Safari.
  • It will work on faster mobile devices, but the page is not responsive

Detection

  • The detection method is relatively crude - it has no depth perception, so a hand in front of your face will set it off.
  • A face is considered anything with one eye and a nose (according to its detection)
  • It usually does not detect as well if you are very close to the camera.
  • It is not optimized to handle multiple people

CPU Utilization

  • BodyPix can be CPU intensive on some devices - it will not work well on slower devices
  • If the FPS drops below 5 FPS, try using the Fastest setting
  • It works best if you can keep the browser tab in the foreground so background throttling is not invoked

Pull Request

The CSS fixes from dharmadeveloper108 are much appreciated!
