Google began works on their new system named Fuchsia. Future of this project isn't clear - some people say, that Fuchsia can even replace Android and Chrome OS in new projects of Google. To be honest, only Google workers know what company plans for future, but one is certain - works on the system are ongoing, but so far they are at a very early stage.
First thing which catches people's attention is "Magenta" kernel, which is used instead of Linux. Apps for this system are supposed to be cross-platform. When it comes to topic of graphics, new interface of this system has name Armadillo. System bases on gesture control, and if you want to test it, there is possibility to run this new graphic interface on Android - on the Internet appeared .apk file which works like normal app on Android and by using it we can take a look how Armadillo will probably work.
However, how we mentioned above, Fuchsia OS is in early stage and many things in Google's plans may change. It's not even certain if project will be ended successfully, but idea looks interesting and it's worth to keep up to date with this venture.
