Description

  The present invention relates to a mobile phone, and more particularly to the technology of a mobile phone having a numeric keypad.

  In recent years, in mobile phones, in addition to using a telephone function, means for communicating with others using a mail function, a chat function, etc. has been regarded as important. Immediate communication is not required for e-mail compared to telephone communication, but because users generally send e-mail more frequently than to make a call, the user has a desire for functions and means that can input characters quickly. There is. A mobile phone has fewer buttons than a personal computer keyboard, and for a user who can input characters on a personal computer, it may take time to input characters on the mobile phone and feel annoying.

  In this regard, Patent Document 1 discloses a cellular phone in which five sensors are provided for each numeric keypad and a clear sound can be input by one press when the numeric keypad is input on the cellular phone.

  Further, in Patent Document 2, in a character input method for a small portable terminal, a key to be pressed first and at least one key horizontally, obliquely and vertically adjacent to the key to be pressed first are within a predetermined time. There is disclosed a method capable of inputting characters at high speed by a combination of character codes obtained by a combination of character codes obtained by consecutive keystrokes.

Further, Patent Document 3 is composed of a representative switch group capable of selecting consonants and one member switch capable of selecting vowels. After selecting the representative switch, the character switch is slid by touching the member switch including a touch panel. A character input device for determination is disclosed.

  However, in the technique described in Patent Document 1, five pressure sensors are provided in one numeric keypad, and an input character is determined depending on which sensor among the five pressure sensors responds. The interval between the five sensors is narrowed and malfunctions are likely to occur. Further, when the interval between the numeric keys is narrowed, an erroneous operation in which an adjacent key is accidentally touched also occurs.

  In the technique described in Patent Document 2, a clear sound can be input by at least pressing a nearby key twice. However, the second press for determining a vowel differs depending on the arrangement of the key pressed for the first time. For those who do not know which key is pressed to input a desired character, there is an annoyance that the user must always input characters while dividing the case with the key pressed for the first time.

  In the technique described in Patent Document 3, characters are input using a touch panel. However, since the representative switch group and the member switches are located at positions apart from each other, input using only one hand causes unnecessary movement of the finger. Takes time. Furthermore, since the member switch is touched and the character is determined by the slide distance, it is difficult to know how much the desired character can be input by sliding the member switch.

  The present invention has been made in view of the above-described conventional problems, and even when the input key is small, it is easy to input, the input method is easy to learn, and characters can be input without unnecessary movement of fingers. An object is to provide a mobile phone.

[Fifth Embodiment]
A fifth embodiment of the present invention will be described. The same parts as those in the above embodiment are given the same reference numerals, and the description thereof is omitted. Further, description of similar effects is also omitted. In the present embodiment, only the operability will be described regardless of whether the key operation unit 4 is implemented on the touch panel 5 and whether or not it has a touch sensor.

  In the above-described embodiment, it is possible to input a clear sound by selecting a consonant to the key operation unit 4 and subsequent vowel selection, but in this embodiment, through further operations after the vowel selection described up to the fourth embodiment, It is possible to input various characters (special characters) such as muddy sound, semi-turbid sound, prompt sound, and roar.

  FIG. 7 is an explanatory diagram for explaining an operation input using a mobile phone. Here, the conversion process is shown by citing “tsu” which is a clear sound. First, assuming that the vowel “u” is selected in accordance with the rightward sliding operation after the detection of the consonant “t” by the operations described up to the fourth embodiment, the mobile phone uses the character input at this time. Is recognized as “tsu”. Thereafter, when the user performs a slide operation for drawing a circle without releasing the finger from the key operation unit 4, the mobile phone recognizes the operation and performs further character conversion on “T”.

  For example, as shown in FIG. 7A, when an operation that draws a circle counterclockwise (counterclockwise) from the position where “tsu” is selected is detected, the mobile phone recognizes the cloudy sound “zu”. To do. In addition, when an operation that draws a circle in a clockwise direction (clockwise) is detected, the mobile phone recognizes the prompt sound “tsu”.

  By a series of operations on the key operation unit 4, muddy sound, semi-muddy sound, prompt sound, and roar can be selected easily and reliably. In addition, the operability is greatly improved by a sensory operation such as turning back a finger in the counterclockwise direction or the clockwise direction.

  Such conversion from clear sound to muddy sound, semi-turbid sound, prompt sound, and stuttering can be easily performed without complicated calculation processing by referring to a predetermined character conversion table.

  FIG. 8 is an explanatory diagram showing an example of a character conversion table. Here, the character is uniquely determined according to the conversion operation in the counterclockwise direction or the clockwise direction with respect to the pre-conversion character (quiet sound) that can be a character conversion target according to the fifth embodiment. In such a character conversion table, the principle of muddy sound if counterclockwise, and semi-turbid sound other than muddy sound, prompting sound, and roaring is applied if clockwise. Here, when drawing a circle attached to a semi-voiced sound, most right-handed people draw a clockwise trajectory. Can input muddy sound. Therefore, it can be associated that the muddy sound in the contrasting relationship can also be converted in a contrasting counterclockwise direction, and can be easily converted. Hereinafter, the operation will be described with reference to an example of “ha” line in which muddy sound and semi-turbid sound can be selected.

  FIG. 9 is an explanatory diagram for explaining an operation input using a mobile phone. For example, as shown in the center of FIG. 9A, after the character “ha” is determined, when a counterclockwise operation is detected continuously, the character is converted into a muffled sound “ba”. When a clockwise operation is detected, the character is converted to a semi-turbid sound “Pa”. 9B to 9E, as in FIG. 9A, a counterclockwise or clockwise operation is detected and a muddy sound or a semi-turbid sound is selected.

  In the character conversion table, the muddy sound and the semi-turbid sound are associated counterclockwise and clockwise, respectively, but the association can be arbitrarily set or changed.

  In the description using FIG. 7 and FIG. 9, the counterclockwise and clockwise operations are cited as triggers for executing the character conversion. However, the present invention is not limited to such operations, and can be applied to various operations similar to the operations.

  FIG. 10 is an explanatory diagram for explaining another operation input using the mobile phone. For example, even if a complete circle is not drawn counterclockwise, the conversion operation can be recognized by a semicircle or a circle less than that (half rotation locus) as shown in FIG. Further, the conversion operation is recognized even in a polygonal input locus (polygonal locus) such as a triangle which is not a circle as shown in FIG. Furthermore, as shown in FIG. 10 (c), if the direction of moving the finger is simply changed (L-shaped trajectory) and if it can be determined whether the direction is counterclockwise or clockwise, the conversion operation is recognized. be able to.

  In such a cellular phone character input, it is assumed that a plurality of characters are continuously input. Therefore, when a counterclockwise or clockwise circle is required for character conversion to muddy sound, semi-turbid sound, prompt sound, and roaring sound, The case where the easy operation input by embodiment is interrupted on the contrary may arise. In this embodiment, as described above, by recognizing a half-rotation locus, a polygonal locus, and an L-shaped locus, a character intended by the user can be surely avoided while avoiding misrecognition without drawing a complete circle. Can be recognized.

  Also provided is a program that causes a computer to function as the mobile phone described in the first to fifth embodiments.

(Character input method for mobile phones)
A character input method for a mobile phone that performs character input using the mobile phone described above will be described.

  FIG. 11 is a flowchart showing specific processing of the character input method of the mobile phone. When character input is started, the mobile phone waits for character input by the user (step S20), and when a touch on the numeric keypad 40 is detected (YES in S20), a consonant is determined based on the touched key. (Step S21).

  Subsequently, it is determined whether or not the user's touch on the numeric keypad 40 is released (released) (step S22). If the user's touch is released (YES in S22), the character “a” in the consonant is the character input. It is determined as a character (step S23). If not separated (NO in S22), it is determined whether or not a slide operation by the user has been detected (step S24), and if no slide operation has been detected (NO in S24), confirmation of a predetermined time is confirmed. A timeout is determined as much as possible (step S25). If the predetermined time has elapsed (YES in S25), the vowel is determined to be “A” (step S26). If it has not elapsed (NO in S25), the process returns to the standby state for user input.

  Here, the time-out is set for the slide operation after the consonant is determined to select a vowel other than “a”, or to select the muddy sound of the present embodiment after setting the vowel to “a”. This is because it is not possible to identify the slide operation for the purpose. Due to the timeout in step S25 in which the vowel is determined in the “a” stage without moving up / down / left / right from the key, the slide operation before the predetermined time has passed is selected, and the slide operation after the predetermined time has passed is the vowel [ It can be determined that the sound is muddy on the basis of [a]. Further, the determination of the time-out may be configured such that the slide operation before the predetermined time elapses selects muddy sound, and the slide operation after the predetermined time elapses reverses the vowel selection.

  If a slide operation by the user is detected (YES in S24), it is first determined whether or not the slide operation is an upward slide operation on the numeric keypad 40 (step S27), and an upward slide operation is performed. If so (YES in S27), the vowel is determined to be “yes” (step S28). Similarly, if it is in the right direction (YES in S29), the vowel is in the “U” level (step S30), and if it is in the downward direction (YES in S31), the vowel is in the “e” level (step S32), If it is not the direction (NO in S31), it is regarded as the left direction, and the vowel is in the “O” stage (step S33).

  Next, it is determined whether or not a further slide operation on the numeric keypad 40 of the user has been detected (step S34). If a slide operation has not been detected (NO in S34), it has been separated or a predetermined time has elapsed. If it is determined (step S35) and it is determined that it is separated or timed out, a clear character indicated by a consonant and a vowel is determined (S36).

  If a slide operation by the user is detected (YES in S34), it is first determined whether or not the slide operation is counterclockwise on the numeric keypad 40 (step S37). (YES in S37), it is confirmed that the character is the target character of the dakuten (step S38), and converted to a dakuten with reference to the character conversion table (S39). If it is determined that the direction is not counterclockwise (NO in S37), the slide operation is regarded as a clockwise slide operation, and the character is a target character for half-cloudy, prompting, and stuttering. This is confirmed (step S40), and the character conversion table is referred to and converted into a semi-voice point, a prompt sound, and a stuttering sound (step S41). Finally, the converted character is determined and the character input is terminated (step S36).

  In addition, when an adjacent key is accidentally touched during character input (before character determination), the operation may not be recognized as a new character input. In this way, erroneous input is prevented.

  Furthermore, instead of the above-mentioned timeout, it is possible to shift to the processing after the timeout without waiting for the timeout by continuous touch (tap) with a short time interval.

  Even according to the character input method of the mobile phone described above, the vowel selection after the determination of the consonant can be performed simply by moving away from the predetermined key, pressing the predetermined key for a predetermined time, or sliding in a predetermined direction based on the predetermined key. Since it can be performed by operation, it is possible to easily and reliably select a character and reduce erroneous input regardless of the size of the key operation unit 4 itself or the reduction in the interval between keys. Further, since the existing arrangement of the key operation unit 4 is used as it is, the operability can be improved while maintaining the user's operation feeling.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various conversions or modifications can be conceived within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  Here, the direction of sliding to determine the vowel is not limited to up, down, left, and right, and an oblique direction may be used as appropriate. For example, when determining the vowels in the “ya” row, “a” may be set as an upper slide, “u” may be set as a lower right slide, and “o” may be set as a lower left slide.

  Here, when each key has a touch sensor and the touch sensor has a function of determining whether or not the key is touched, the touch sensor is touched only when most of the keys are touched. It is good to judge that there is. Moreover, it is good to install a touch sensor only in the center part of a key. By adopting such a configuration, malfunction during sliding can be prevented.

  In the present embodiment, description has been made with a numeric keypad having a frame, but the present invention is not limited to this.

  In the present embodiment, a mobile phone having at least a part of a 5 × 3 key array in which a 5 × 3 key array or a 1 × 2 key is missing has been described. It is not limited to. This is because even when the numeric keys are randomly arranged, vowels can be determined by short pressing or sliding up, down, left and right after touching. Furthermore, the matrix representation such as 5 rows and 3 columns is not a matrix representation in a strict sense, and one or a plurality of keys in the matrix may not be arranged in an orderly manner as compared with other keys. Furthermore, the buttons in the matrix need not have the same shape. For example, in the mobile phone shown in FIG. 2, the key is missing in the first row and the second column. 48 may be regarded as a key in the first row and the second column, and the present invention may be implemented.
