Website Response Times An Article by Jakob Nielsen www.nngroup.com Users really care about speed in interaction design...A snappy user experience beats a glamorous one, for the simple reason that people engage more with a site when they can move freely and focus on the content instead of on their endless wait. 0.1 seconds gives the feeling of instantaneous response. This level of responsiveness is essential to support the feeling of direct manipulation. 1 second keeps the user's flow of thought seamless. 10 seconds keeps the user's attention. A 10-second delay will often make users leave a site immediately. uxperformanceinteraction
In the Eye of the Beholder An Essay from Field Notes on Science and Nature by Jonathan Kingdon Haven't you noticed?Wordless questioningOutlinesAgents of thought and experiment
Haven't you noticed? I remember my mother sitting me down at the age of about five with pencil and paper to draw an acacia tree in the yard while she busied herself with her own sketchbook. After a while she came over to see my efforts. “Splendid! But haven’t you noticed how the trunk narrows as it rises? And see how the branches flatten out sideways, not like that oleander over there, where they all go up at a steep angle. Now don’t rub that one out, just do another drawing to compare with the first one.” Looking Closely is Everything seeing
Wordless questioning The comparison of forms raises questions and drawing can be employed as a wordless questioning of form; the pencil seeks to extract from the complex whole some limited coherent pattern that our minds and eyes can grasp. The probing pencil is like the dissecting scalpel, seeking to expose relevant structures that may not be immediately obvious and are certainly hidden from the shadowy world of the camera lens.

Outlines Photography teaches us that the very act of putting a line around the edge of an observed object is an artifice. Such outlines rarely appear in photographs, or, for that matter, in nature, and yet…and yet? An outline sketch that bears little relationships to the so-called objectivity of a photograph might actually transmit information to another human being more selectively, sometimes even more usefully, than a photograph. If the brain is unlike a camera in actively seeking outlines, there is the strong implication that “outline drawings” can represent, in themselves, artifacts that may correspond more closely with what the brain seeks than the charts of light-fall that photographs represent.
Agents of thought and experiment The act of drawing serves to remind us that hands are agents of thought and experiment. Photography has a great future, but no matter how much ancillary wizardry photography accumulates, it will not be in competition with “drawing” in the broadest sense of that term. There will always be a role for exploration by the hands, encumbered by no more than a piece of ocher or a stick of charcoal. Its practical utility is as a manifestation of the mind struggling with the meaning of what it encounters and what it wants to explore. thinkingdrawingunderstanding
