The real solution is a family robot that monitors consumption of household items in a smart home and orders everything that you need in a timely manner.
The world is moving towards connected homes, connected cars, connected fridges etc, why the hell would you want individual stick on buttons, that would be silly.
This is clearly an April fools campaign. This approach is simply not the most viable. How many buttons are you going to have in your household? How are you going to protect it from kids etc!
Comparing screenshots (difference thresholds) is probably the most complicated part of the process. Currently using Imagemagick which is OK but it could be improved, probably by using Open CV instead.
