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
Sonic architecture An Article by Daisy Alioto dirt.substack.com Brian Eno is well-represented in iOS. His other apps like Bloom, Trope and Air invite listeners to touch the screen to make their own composition. Reflection ($30.99) is different, there is no interaction for the listener. The interface has three buttons: a pause button, a sleep timer, and AirPlay. Reflection produces endless permutations of Eno’s 2017 album, an hour and five minute long title track. “Just calling it an app is akin to saying Falling Water is just a building,” writes one app store reviewer. “I would not call this an app,” agrees another, “Between the music and visuals it’s more like sonic architecture.” The visuals consist of slowly morphing rectangles that only seem to change in the split second you look away from the screen. architecturesoundmusic
