Thereafter, the input character setting unit 14b determines whether or not the user's finger 23 has been released from the touch panel 12 (step S108). When the user's finger 23 is not separated from the touch panel 12 (NO in step S108), the process proceeds to step S104, and the movement distances Lx and Ly of the touch position of the finger 23 in the X-axis direction and the Y-axis direction are set. The detection process is executed again, and the subsequent processes are continued.
- step S108 input character setting unit 14b changes the character corresponding to character input key 22 selected in step S106 to the input character input by the user. Setting is made (step S109). Then, the display unit 11 deletes the key layout information 60 (Step S110).
- the display unit 11 performs a pop-up display of the character set as the input character in step S109 (step S111). Then, the input character setting unit 14b adds the character set as the input character to the sentence being edited (step S112), and ends this character input process.
- the present invention is not limited to these embodiments, and a computer program for realizing the functions of the character input device.
- the present invention may be implemented in the form of a computer-readable recording medium in which the computer program is recorded.
- a recording medium for example, a disk system (for example, magnetic disk, optical disk, etc.), a card system (for example, memory card, optical card, etc.), a semiconductor memory system (for example, ROM, nonvolatile memory, etc.), a tape system (for example, various forms such as a magnetic tape and a cassette tape can be employed.
- a disk system for example, magnetic disk, optical disk, etc.
- a card system for example, memory card, optical card, etc.
- a semiconductor memory system for example, ROM, nonvolatile memory, etc.
- a tape system for example, various forms such as a magnetic tape and a cassette tape can be employed.
- the cost can be reduced, and the portability and general purpose can be reduced. Can be improved.
- the above-mentioned recording medium is mounted on the computer, the computer program recorded on the recording medium is read out by the computer and stored in the memory, and the processor (CPU: Central Processing Unit, MPU: Micro Processing Unit) included in the computer is the computer program. Is read from the memory and executed, the function of the character input device according to the present embodiment can be realized and the character input method can be executed.
