The name is shorthand for Asynchronous JavaScript + XML, and it represents a fundamental shift in what’s possible on the Web.” Jesse James Garrett Co-founder, Adaptive Path

Compelling User Experience

Jef Raskin Noted Usability Expert “ e quality of any [so ware] is ultimately determined by the quality of the interaction between The Humane Interface one human and one system.”

Jef Raskin Noted Usability Expert “If a system’s one-on-one interaction with its human user is The Humane Interface not pleasant and facile, the resulting de ciency will poison the performance of the entire system, however ne that system might be in its other aspects.

First Wave of Ajax Making JavaScript Better Simple Effects Responsiveness is the killer app

CSS and Animations dojo.query(quot;#nav > .focusablequot;). attr(quot;tabIndexquot;, 0). style(quot;borderquot;, quot;1px solid transparentquot;). anim({ quot;borderColorquot;: { start: quot;yellowquot;, end: quot;whitequot; } });

Jakob Nielsen Noted Usability Expert

Jakob Nielsen Noted Usability Expert “ e basic advice regarding response times has been about the same for thirty years:

“0.1 second is about the limit for Jakob Nielsen Noted Usability Expert having the user feel that the system is reacting instantaneously, meaning that no special feedback is necessary except to display the result.

Jakob Nielsen Noted Usability Expert “1.0 second is about the limit for the user's ow of thought to stay uninterrupted, even though the user will notice the delay.

Jef Raskin “If [a] feature is well–designed, Noted Usability Expert and if we use it repeatedly, we eventually... use the feature The Humane Interface habitually, without thought or conscious e ort.

“In operating an interface we combine or ‘chunk’ sequences of actions into gestures, which, once Jef Raskin Noted Usability Expert started, proceed automatically. Because we form gestures, techniques such as having a user The Humane Interface respond Y or N to an ‘Are you sure?’ veri cation do not provide safety: e typed ‘Y’ becomes part of the gesture.”
