In Japanese, Hitogenome associate with a person, and Ubiquities often associate with a finger.

Due to the progress of IT (information technology), Ubiquities computing society that means "always", "wherever", "anyone" can use computer is approaching, continuously a large computer, a personal computer.

IT becomes indispensable, and there is no person who can't be handled now from the young member until the middle height age in the business society.

It is home that is left.

It will become 100% of the diffusion rates when housewife, children and elders become use computer.

It will be no problem in case of children, next is housewife, and final will be elders.

The thing, which put a big dial and a knob, is a hit on the radio as well.

These were being called universal design, and it aimed at anyone using it without any relations such as age, sex, the person in healthy or not, a handicapped person.

Well, the present cannot be all right as for the personal computer as well to realize "anyone" of Ubiquities.

It is impossible to the old man with those small keyboards.

The size of the character is also same.

As for enlarging a character, in other words big display is necessary.

When it is so, a desktop computer becomes more favorable than the notebook.

There are too many unnecessary functions, too.

If it only enjoys mail and the Internet, you must make it the way of using it that about a fixed telephone vessel.

Radio IC tag is in the limelight.

It is composed of the IC (accumulation semiconductor) chip and the antenna.

It is effective in tracerbility (history chase) of the meat-manufactured goods, which are a problem further as well.

It is security to be important at the end.

It pointed at an input device such as a keyboard that it was called man-machine interface by the computer technology.

It has been problem with low speed of input work by men compared with super-high speed of the CPU.

But, as for being important of man-machine interface, it will be in the human ethics more than the technology and/or security.
