An upcoming feature in Cloudfier is the automatic generation of fully functional user interfaces that work well on both desktop:
and mobile browsers:
This is just a first stab, but is already available to any Cloudfier apps (like this one, try logging in as user: firstname.lastname@example.org, senha: Test1234). Right now the mobile UI is read-only, and does not yet expose actions and relationships as the desktop-oriented web UI does. Watch this space for new developments on that.
The case against generated UIs
Cloudfier has always had support for automatic UI generation for desktop browsers (RIA). However, the generated UI had always been intended as a temporary artifact, to be used only when gathering initial feedback from users and while a handcrafted UI (that accesses the back-end functionality via the automatically generated REST API) is being developed (or in the long term, as a power-user UI). The reason is that automatically generated user-interfaces tend to suck, because they don’t recognize that not all entities/actions/properties have the same importance, and that their importance varies between user roles.
Don’t get me wrong, we strongly believe in the model-driven approach to build fully functional applications from a high-level description of the solution (executable domain models). While we think that is the most sane way of building an application’s database, business and API layers (and that those make up a major portion of the application functionality and development costs), we recognize user interfaces must follow constraints that are not properly represented in a domain model of an application: not all use cases have the same weight, and there is often benefit in adopting metaphors that closely mimic the real world (for example, an audio player application should mimic standard controls from physical audio players).
Enter mobile UIs
That being said, UIs on mobile devices are usually much simpler than corresponding desktop-based UIs because of the interaction, navigation and dimension constraints imposed by mobile devices, resulting in a UI that shows one application ‘screen’ at a time, with hierarchical navigation. So here is a hypothesis:
Hypothesis: Mobile UIs for line-of-business applications are inherently so much simpler than the corresponding desktop-based UIs, that it is conceivable that generated UIs for mobile devices may provide usability that is similar to manually crafted UIs for said devices.
What do you think? Do you agree that is a quest worth pursuing (and with some likelihood of being proven right)? Or is the answer somehow obvious to you already? Regardless, if you are interested or experienced in user experience and/or model-driven development, please chime in.
Meanwhile, we are setting off to test that hypothesis by building full support for automatically generated mobile UIs for Cloudfier applications. Future posts here will show the progress made as new features (such as actions, relationships and editing) are implemented.
