Keeping the GUI simple with the HUI

The Hidden User Interface

As we strive to maintain the "easy as dirt"* usability of the Graphic User Interface (GUI) in our open source Salsa application, we are creating a customizable User interface that lives "beneath" the GUI. We have even coined an original term: Hidden User Interface (HUI).**

We're still fleshing out the concept, but here are some thoughts:

GUI

1. Achieve simplicity and beauty through "ruthless reduction" (inspired by Fedarko's description of dories in The Emerald Mile).
2. Provide an interface that is accessible for all Users.
3. Maintain a common "top-level" interface to support interactions between Users: collaborative creation of SALSAs, feedback, coaching. 
4. Maintain a common "top-level" interface to optimize resources and services provided for Users: documentation, training, support.

HUI

1. Provide the ability to adapt to a User's spatial and/or visual preferences.
2. Allow the User to select the level of instructional scaffolding that is visible.
3. Allow Users to also share HUIs through the "Template Link" (currently allows a User to share content without creating a User account).
