NTT Docomo Showcases Smartphone Prototype with See-through Touch Panel

NTT Docomo and Fujitsus have jointly developed a smartphone prototype with a 2.4″ see-through OLED display (QVGA) that has touch sensors both on its front and back sides and NTT Docomo is currently exhibiting the device and showcasing the corresponding new innovative user interface at Wireless Japan 2012, until June 1, 2012, in Tokyo.

NTT Docomo See-through Display Smartphone Prototype

The backside touch panel can be operated by using the forefinger and there are several ways to take advantage of a see-through display in the UI including:

  • Operate the notification bar from the back side of the panel with a finger
  • Hold an icon with a finger of one hand from the back side of the panel and stroke the front side of the panel with a forefinger of the other hand to move the home screen on which the icon is placed
  • Play Rubik’s Cube by spinning the cube when the back side is not being touched and moving the cube parts when it is “held” on the back side of the display.

Diginfo has a video showing the device.

The device is still in development as NTT Docomo would need a bigger display for commercialization and several technical challenges have yet to be resolved such as low brightness, so a device using this technology may only become available in a few more years.
