No. I simply mean that if you, say, click a link on a web page, predicting that it will land you on the About Us page, and it does indeed land you on that page, then that would be deemed to have a high level of usability. Likewise, if you click a command link or button—regardless of whether it triggers an Ajax function or loads a new page or whatever—as long as you can predict the result (not the UI result, but the net result), then it's usable. For example, you click a Save button believing it will save whatever you've been working on. It doesn't matter if the resulting success indicator is on another page or the same one, what matters is that you were able to accurately and correctly predict what effect the button would have. If the interaction is clear and understandable, it doesn't matter if it's an old classic or brand new and revolutionary. The subject line of this thread refers only to whether or not you can predict the outcome. You can innovate all you want as long as what you design is understandable and the outcome predictable, can you not? Of course, as we've already seen, not all things must be predictable to be usable, so this is all a moot point now. :) Again, just playing devil's advocate here. -r- ________________________________________________________________ Welcome to the Interaction Design Association (IxDA)!
