Hi Mike, Thanks for your comment. I agree with you that a linear representation of the Timeline on a scrollbar would not be helpful.
But at the same time, we need to explore additional visual cues about scrolling. I've been doing UI testing with Timeline and people just don't grasp the concepts by themselves. Of course, in many use cases, formal or informal training will be available to users. But in others, they will be on their own. My thought was more towards something both non-linear and also non-representational. Eg have the handle on the scrollbar jump back to the center after every use by the user. (The handle's position on the scrollbar would NOT show where you are on the Timeline. Or maybe only for Timelines with Start and Stop dates defined.) And the way the arrow keys give a non-linear movement response the longer you hold them down is also useful for trying with a horiz scrollbar widget.

A single-pixel adjustment to the scroll thumb might cause very large jumps in time on the timeline. Timeline already supports the ability to scroll, so I think a better solution would be to give the user more cues that they drag the timeline to scroll. When google maps first came out, people had difficulty with the concept of dragging the map itself to scroll - they were so used to the circle of buttons around the map. But this isn't an issue any more. The rest of the changes, with the exception of the new painter, are easily supported with what we have now. --Mike --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "SIMILE Widgets" group.
