Markham Panels

I propose a user interface standard for an Executive Information Service (EIS) for modern humans. Let's call them Markham Panels. The interface abides by these rules:

• Only one screen. No setup screens, configuration
• Only three things are allowed on the screen, indicator lights (which also function as buttons), a list/text/video view, and gauges/graphs. The gauges graphs may be of various types, but there can be only one type per panel
• No fonts
• No hyperlinks
• No keyboard
• The machine may make sounds and/or speak, but it may not alert the user on it's on for more than .1% of the user's time on the device
• Likewise there will be certain rules for how often an indicator light may light/flash, and at what intensity.
• Combining the numbers of controls with these standards of allowable interruption frequency should produce a panel complexity factor for that particular configuration
• The list/video/view is small compared to the rest of the screen, and it is the only screen that is allowed to change. It may not change on its own
• Interacting with other folks in the world is either done by pushing a button or speaking. The person is not allowed to create text, nor will the system try to learn speech recognition by pestering the person (That doesn't mean that such work can't be outsourced, though)
• No direct interaction with the list/text/video frame is allowed aside from selecting items on the list
• Configuration of the system is extremely flexible, but happens offline through another system which is not immediately accessible to the user

I believe such a system is capable of performing most all of the knowledge work required by modern civilization, aside from programming and other arts (writing, graphic design, painting, music composition, etc) I also believe that deploying these panels would result in tremendous gains in productivity. (Although I think that free-form exploratory computing also has a huge role, I doubt that the benefits outweigh the drawbacks, at least in many contexts)

EDIT: I initially put "Prove me wrong." as a close, but that sounded a little too over-the-top, even for me. Perhaps a better close to this post would be "I welcome the chance to change this to add controls as needed"

The goal here is to discuss and explore extreme minimal interface standards. I'm throwing this out as a starting point.
