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
Your only language is vision To see with fresh, uninstructed eyes and an open mind requires a deliberate, self-aware act by the observer. Abstract artworks represent themselves and should be first viewed for themselves. When looking at outdoor abstract pieces, concentrate initially on the unique optical experience produced by the artworks. See as the artist saw when making the piece. A focus on optical experience does not deny stories, it postpones them. Viewing an artwork may evoke interesting narratives – or just tedious artchat recalling similar art or artists, concocting playful tales, realizing how scrap metal was repurposed into art, making judgments about the artist's intentions or character, or contemplating an artwork's provenance, price, politics. Let the artwork stand on its own. Walk around fast and slow, be still, look and see from up down sideways close afar above below, enjoy the multiplicity of silhouettes shadows dapples clouds airspaces sun earth glowing. Your only language is vision. Edward Tufte, Seeing With Fresh Eyes Seeing Is Forgetting the Name of the Thing One SeesLearning to See seeingartperception
