It's auto-brightness on a webpage!
Mear oer dizze demo fan de auteur
How to use:
You need to be on a desktop version of Firefox17+, Chrome21+ or Opera12+ to use getUserMedia. You also need a web cam of course.
This time, the demo just serves news from Feedzilla which you can read anywhere, anytime, and any lighting condition!
It's similar to the auto-brightness of a smartphone. It uses the video streamed from the web cam to calculate the brightness of the surrounding area. In this demo, the values are used to toggle styles. The brighter the surroundings, a brighter style is applied. If the surroundings are dark, then a darker style is applied. It also uses CSS transitions to smoothen style changes.
This demo uses the same code I used in my previous demo, minus the canvas libraries. And in place of the motion-detection code is the code that calculated for luminosity.
