New mobile devices concepts emerge constantly.
My favorite is Project Rimino. It’s a concept based on a user interface inspired by print posters. It’s very good looking and user friendly. The people over at Umea Institute of Design have created a detailed page with their inspirations for the concept. Definitely worth looking at.
Another interesting concept is “A day made of glass” by Corning Glass. As you have guessed it’s about devices with glass interface.
It seems designers have understood that buttons on devices are no longer popular. Let’s hope that we’ll see elements of these concepts in production devices in the near future.
