NTT Docomo have developed a prototype smartphone that works through touch on the front and back, using touchpanels on both sides of a see-through display.
This smartphone is being co-developed by Docomo and Fujitsu. By using it from the back, you can scroll the screen without obscuring the display, and reach the slide down notification bar easily with your index finger. Docomo also implemented a new way of using smartphones, by touching both sides at once.
