Abstract

Disclosed is Japanese Roman alphabet input method for a device with few keys like the telephone. At a present, it is not so easy to input Japanese characters using "direct Kana input" that it is adopted with all the telephone (refer to a figure 1). Therefore, this invention uses the "Roman alphabet input" that it is adopted widely with IME of the personal computer and workstation, instead of "direct Kana input". Furthermore, to increase user interface, only 20 characters of the minimum necessary for "Roman alphabet input" are adopted (refer to a figure 2), and a consonant, a voiced sound and a semi-voiced sound are arranged in the same key (refer to "6","7","8" and key in the figure 2). For example, in case of figure-1, when pushing "1" "1" "1" "1" "1" "1" "2" "2", "···" is indicated in the display. On the other hand, in case of figure-2, after pushing "1" "5" "6" "2", the software of Roman-Kana conversion changes into "···", and then it is indicated in the display.

Roman input method for few keys

Disclosed is Japanese Roman alphabet input method for a device with few keys like the telephone.
At a present, it is not so easy to input Japanese characters using "direct Kana input" that it is
adopted with all the telephone (refer to a figure 1). Therefore, this invention uses the "Roman
alphabet input" that it is adopted widely with IME of the personal computer and workstation,
instead of "direct Kana input".

Furthermore, to increase user interface, only 20 characters of the minimum necessary for "Roman
alphabet input" are adopted (refer to a figure 2), and a consonant, a voiced sound and a
semi-voiced sound are arranged in the same key (refer to "6","7","8" and "*" key in the figure


2).

For example, in case of figure-1, when pushing "1" "1" "1" "1" "1" "1" "2" "2", "···" is
indicated in the display. On the other hand, in case of figure-2, after pushing "1" "5" "6" "2",
the software of Roman-Kana conversion changes into "···", and then it is indicated in the
display.
