ISSUE-57: qualify your interrupts; communicate subliminally always and through the focus rarely (public comment) http://www.w3.org/2006/WSC/Group/track/issues/57 Raised by: Bill Doyle On product: Note: use cases etc. >From public comments raised by: Al Gilman Alfred.S.Gilman@ieee.org http://lists.w3.org/Archives/Public/public-usable- authentication/2007Apr/0000.html qualify your interrupts; communicate subliminally always and through the focus rarely. where it says, in 10.1.5 Single locus of attention A user has only a single locus of attention, a feature or an object in the physical world, or an idea, about which they are intently and actively thinking. Humans ignore things that aren't their current locus of attention. The user's locus of attention is only held in short term memory and so will be quickly forgotten once their attention shifts. please consider This paragraph sounds as though the security status should be contending for the user's attention along with their main-line task. This could lead to mis- design. This principle is likely to mislead the design if not taken with a large grain of salt. The point here is that the comfort level of the user with the current context is typically much more unconscious than is their concept of what they are focused on. Humans react subliminally to stylistic effects that connote changes in context or context continuity in a way that suffuses many of these narrow 'loci of attention.' You could be about to throw the baby out with the bathwater. Many in the Web think that interactive behavior and text effects such as color and underline are 'presentation' that is disjoint from 'content.' But nothing could be farther from the Web truth. Color or underline subliminally communicates what is clickable to the visual user, and clickability is essential to the user's concept of web browsing. the web would be a laboratory artifact still if this closure of the interaction cycle through style and behavior weren't in place. And it works without the user ever focusing on it. It plays into pre-focus scanning behavior. You have amply demonstrated that just like clickability, trustworthiness is something that users judge subliminally. Our difficult task is in presenting a trickle of nuisance events (small enough so they don't decide it's the boy crying wolf) that will get them to exercise a modicum more skepticism in the nick of time. please consider event sounds and ShowSounds, introduced before.
