Some of the more enjoyable surfaces (for example, the grain of a fine mahogany table top or a Japanese sword) have an interplay between pattern and texture which, though two-dimensional, suggests the unseen internal three-dimensional array.
As we draw closer, we see that the three-faceted planes of the museum are fabricated out of rectangular panels made of white bronze that was poured directly into dammed forms on the concrete floor of the foundry, producing a surface texture similar to both metal and stone.
I’m now more inclined to attribute Looseleaf’s power to its visual texture than to some cognitive media-style abstraction. And the visual texture owes more to the beauty (yes, beauty!) of the original pdfs from the Vasulka Archive. Perhaps the demo is best understood not as a prototype generic tool, but as a specific curated experience in its own right, with form and content claiming equal importance in its overall success.
Even so, I think there are some general lessons that can be drawn from this demo:
Content is not inert
Visual texture lets content breathe
Visual texture lets the eye wander without losing itself
Users really care about speed in interaction design...A snappy user experience beats a glamorous one, for the simple reason that people engage more with a site when they can move freely and focus on the content instead of on their endless wait.
0.1 seconds gives the feeling of instantaneous response. This level of responsiveness is essential to support the feeling of direct manipulation.
1 second keeps the user's flow of thought seamless.
10 seconds keeps the user's attention. A 10-second delay will often make users leave a site immediately.
