Ajax Dialog Windows

Category: UI, Usability

Luke Wroblewski, a usability guy, has written about Ajax Dialog Windows.

He analyzes the new world of poping up dialog windows, rather than having to send people to new pages for those tasks.

This technique makes perfect sense when:

  1. You only need to capture a little content
  2. You don’t want to end up on a different page after that information is submitted (and hence you don’t have to go to a new page, and then get sent back. You get to just stay on the page!)

We must remember the visual

As Edward Tufte pointed out in Visual Design of the User Interface (1989):

“The border of an active window should be light in value (to avoid
clutter with other windows), yet deeply saturated (to provide a
conspicuous signal). Yellow is the only color jointly satisfying those
conditions, and therefore proves valuable for bordering windows.” –Window Research: Color Guidelines

Tufte’s analysis may explain why yellow backgrounds
are often the preferred choice for differentiating dialog content from
the rest of a user interface.

Not so mellow yellow

I agree this kind of technique is good from a general usability point of view, but how does it fair from an accessibility point of view? For example how would a screen reader cope with an example like the above?

Yeah, I agree with Lan, now with this tech, we can make GUI of web become strongly like Application in windows..the problem is speed of web.I think If we apply this to our web. not too much but I’m sure that speed of loading will lower than normal…
