Decluttering

A group of scientists at MIT headed by Ruth Rosenholtz, a long-time researcher into vision and technology, has developed a prototype application in MATLAB that determines the amount of clutter on-screen (Link). The HCI profession has long needed something that could separate figure from ground reliably. The program is only in prototype, but apparently it's rather promising.

The problem of figuring out what's vital few from trivial many isn't trivial itself. Nuclear facility control rooms are a case in point. Rows of lights can go from being background hum to suddenly becoming extremely important. How much do you expose to an operator, or to a website user? Hicks Law was an early attempt at measuring how much stuff was too much, but the sophistication of control schemes today needs a better way of knowing when you've overstuffed the interface.
