Demonstration of "Rear input interface" using new input form, reverse side of terminal

Although the interface for inputting characters such as keyboard and touch panel to the terminal is usually on the front side of the terminal, demonstration demonstration of "rear input interface" using the back side of the terminal as a new approach is "CEATEC JAPAN 2010"Was held at the KDDI booth.

It is thought that many people are not familiar with the interface, but what kind of content is it?

Details are as below.
"Rear input interface" corner in KDDI booth. While popularization of smartphones has increased the usage approach closer to PCs of mobile phones, it seems that research and development are in progress so that it can be input conveniently and comfortably by using the back side.


This is a prototype of the back input terminal. Turn hands behind and operate.


It is like moving the cursor.


Looking at the movie will look something like this.

To see how exactly the back input is realized, I peeked into the back side of the terminal and I found out how a full keyboard was.


This prototype seems to realize the back input by using the touch sensor mounted on the full keyboard. If you have a keyboard on the back, you will not know which key you are pressing, but by solving the problem by feeding back the position of your finger.


Whether or not it will be put to practical use depends on the future research and development situation, but since it is possible to secure enough wide space for input if it is on the back side, the possibility of spreading mainly in small terminals is It may be there.
