The design concept is based on very advanced haptic technologies: transformable materials and tactile display technologies.
1. Changing the shape
You have unread messages
Call notification by waving its front surface
3D file management: Icons and folders are embossed on the tactile display.
3D map: a mobile version of X-men’s tabletop display
Real button emulation
Ebook reader: see the lower right corner of the display. You can find a curl like a real book.
Braille display for the blind
3. Make it unique
Make your phone unique by customizing the front surface
PS: Below is a possible mechanical structure of the tactile displaying part of the above concept phone. I found it at Yanko Design.
