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
The Finish Fetish Artists An Essay www.getty.edu For others, perhaps especially those artists who worked with light and transparency and were involved in the birth of the Light and Space Movement, an immaculate surface is a prerequisite. Helen Pashgian explained this very clearly: “On any of these works, if there is a scratch... that’s all you see. The point of it is not the finish at all – the point is being able to interact with the piece, whether it is inside or outside, to see into it, to see through it, to relate to it in those ways. But that’s why we need to deal with the finish, so we can deal with the piece on a much deeper level”. The importance of a pristine surface calls for a very low tolerance to damage by the artists. The feeling is shared by Larry Bell: “I don’t want you to see stains on the glass. I don’t want you to see fingerprints on the glass... I don’t want you to see anything except the light that’s reflected, absorbed, or transmitted” Seeing Is Forgetting the Name of the Thing One SeesThe light that hits the glassPhenomenal: California Light, Space, Surface lightartinterfacesmaterial
