Short description
Unplug’d Scans QR codes using your webcam.
Full summary

Boxlight Unplug'd screen streaming client software is the individual user complement to the Unplug'd screen streaming server software provided with Boxlight Series-2 interactive flat panel displays. With Unplug'd, users can mirror your Chromebook's screen and audio to IFPD, and also users can view IFPD's screen from Chromebook.

Scans QR codes and displays their contents on a Chromebook or other computer with a suitable webcam. What's a "suitable" webcam? It's one that can focus the QR code within the red square in the app sharply enough that the app can decode it. My test results:

  • Chromebook Pixel: yes
  • Samsung ARM Chromebook: yes
  • Acer C7 Chromebook: yes
  • CR48: yes
  • 2009 MacBook Pro: yes, except for very small, dense QR codes
  • 2011 iMac: no, unless the QR code is ridiculously large (over one foot across)

If Chrome implements an API to let developers adjust camera-focus settings, I'll be able to improve the app to work with more cameras.
