Google is looking at changing up the rules for interface design, not only on Android like previous leaks have shown, but on iOS and the Web as well. The new approach will be a unified way to design beautiful applications on all platforms, and Google is calling the initiative Quantum Paper.
We believe Project Hera is only a part of Quantum Paper, and Google is looking to completely change the design language for all types of applications, moving from a different look on all three major platforms to one unified look that integrates different buttons and textures.
Google will release a huge new set of tools for Web, iOS, and Android designers, allowing it to create a perfectly unified interface capable of taking advantage of the larger screen on PC, the smaller screen on iOS, and the range of screen sizes available on Android.
Polymer is a good reference for what Quantum Paper will feature. Google announced this at I/O in 2013, and it has received a small amount of fanfare in the web development world. Essentially, this offers new design tools that cater to Web developers who enjoy using HTML and CSS rather than native code on other platforms.
This is what we have been hearing for some time now on Project Hera and Quantum Paper. If the unified development will have one thing in common, it is using HTML and CSS even on mobile platforms despite native apps becoming the preferred way to go.
Quantum Paper will most likely be announced at Google I/O 2014 as a progressive step for Polymer. Google should look to I/O as a way of capturing the biggest crowd of developers in one place to truly embrace the scope of the project and the underlying factors that can make it possible.
There is definitely something going on at Google when it comes to applications design. The company is not happy with the different standards for different platforms, and moving into iOS shows how serious it wants this project to work.
