A question for glanceware practitioners: how to convey multivariate, multistate data at a glance. You have to choose media which we are very good at parsing at a glance. Chernoff faces were an early attempt at this. I guess music would be another good medium to explore. We want users to know things without necessarily knowing how they know, or when they were informed. At one level, glanceware should make knowledge transfer subliminal. Which itself raises the question of when and why we need to convey quantitative or qualitative information.
Imagine a glanceware system to monitor a stock portfolio. Do you need to know what price a given stock is at, or just to pick up, say, a feeling of unease about a particular sector, without necessarily knowing why, with the qualitative data being available to possibly a longer glance, or more conventional drilldown?
