Description

  The present invention relates to an input terminal for inputting information by pressing a key.

  In general mobile phones, function keys such as on-hook, off-hook, and menu are provided in addition to 12 keys “0” to [9], “*”, and “#” for inputting a telephone number. In recent years, the functions of mobile phones have become sophisticated, and various functions are assigned to 12 keys and function keys in order to operate advanced functions. The assignment of these functions differs depending on the operation mode of the mobile phone and is not easy to store. For this reason, it is difficult to determine which function is activated when which key is pressed, which is likely to cause an erroneous operation.

  Even if the function assigned to the key is known, it is necessary to consider use in the dark because the mobile phone can be carried anywhere. When used in the dark, it is difficult to find a key, and erroneous key operations may increase.

  In order to solve these problems, the touch detection pad is placed on the keypad, the touch to the key is detected before the key is pressed, and the characters and functions assigned to the key are detected for the touch detected key. Has been disclosed (see, for example, Patent Document 1). Patent Document 1 describes that in a terminal provided with a contact detection unit on a keypad, when a contact is notified by the contact detection unit, a button corresponding to the key is displayed on the display screen.

  According to this, since the operator knows in advance what kind of key it is before pressing the key, the erroneous input may be reduced even if the function assignment of the key is complicated. Also in the operation in the dark, by searching for the key, it is possible to know from the screen display which key is being operated.

  As shown in FIG. 28, the conventional input terminal includes a touch detection means 50 such as a touch detection pad, a key input means 51 such as a key switch, an output means 54 such as a liquid crystal display, a display screen or a terminal by touch input and key input. And a control means 52 for controlling the operation.

  FIG. 29 is a control flow of a conventional input terminal. In step S501, when a touch is detected by the touch detection unit 50, in step S502, the control unit 52 determines which key is touched. For this determination, the key area table shown in FIG. 30 is used. The key area table shows the area of the X coordinate and Y coordinate of the touch area for each key. In the example of FIG. 30, for example, the key “2” has a range in which the X coordinate is 80 to 150 and the Y coordinate is 0 to 50, and if there is a touch in this range, the control means uses the key “2”. It is determined that "" has been touched.

Next, in step S <b> 503, the output unit 54 displays the function or character assigned to the key on the display device 20. The function and character determination is based on the key registration table of FIG. If the key “2” is touched, the display of the “NW connection” function at the position of the key “2” on the display is changed to highlight or invert the display frame as shown in FIG. Inform the operator that the function is touched. Here, in step S504, when a key press is detected by the key input means 51, the control means 52 operates the function assigned to the key input key.
JP 2002-55766 A

  With these methods, improvements are being made in that the operator recognizes the function assigned to the key, but on the other hand, the advancement of the function is remarkable, and the limited number of keys on the mobile terminal There is a problem that sufficient operability cannot be provided. In order to provide advanced functions within a limited number of keys, the menu hierarchy inevitably increases. For example, there are five or six layers, which is a factor that hinders operability.

  Therefore, in view of the above problems, the present invention provides an input terminal that has a keypad with a touch detection pad and that reduces the menu hierarchy in a terminal that outputs the function of the touched key based on a touch operation on the key. The purpose is to do.

  In order to achieve the above object, the first feature of the present invention is that: (a) a key input means for detecting that the key area is pressed; and (b) at least one key area is A touch detection means for detecting that the touch area is touched by being divided into a plurality of touch areas; and (c) an output means for outputting a character or function corresponding to the touch area detected by the touch detection means. (D) The gist of the present invention is that the input terminal includes an input function determination unit that selects a character or a function corresponding to the touch area when the object is pressed down on a key area divided into a plurality of touch areas. Here, “output means” includes not only output by screen display but also output by sound.

  That is, touch detection means having a touch position detection resolution smaller than the size of the key area is attached to the keypad, the key area is divided into a plurality of subkey areas, and a function is assigned to each subkey area. When a key area is touched, the sub-key area touched in the key area is output to a display screen or the like. The function to be operated is determined depending on which sub-key area is touched when the key is pressed.

  Here, “character” means a key identifying symbol (for example, “2” key is a number “2”), a character assigned to the key (for example, “2” key, “ka” character) "Function" refers to a function or service assigned to a key (for example, "phone book"), a description document of the function or service assigned to a key, content assigned to a key (for example, the name of a captured image) ) Etc.

  According to the input terminal according to the first feature, when a touch detection means in a sub-key area whose touch position detection resolution is smaller than the size of the key area of the terminal is attached to the keypad, Whether the right part of the key has been touched or the left part has been touched can be determined by detecting the touch position. By combining touch detection with a sub-key area smaller than the key area and key pressing, a plurality of functions can be assigned to one key, and selection can be made with almost the same operability as normal key pressing.

  The input terminal according to the first feature further includes touch area storage means for storing the touch area detected by the touch detection means and the time when the contact is detected, and the object is divided into a plurality of touch areas. When the key area is pressed, the input function determination means refers to the touch area and time stored in the touch storage means, obtains a touch area that is in contact with the touch area a predetermined time before the time, and stores the touch area in the touch area. Corresponding characters or functions may be selected.

  That is, a subkey area for determining a function is determined based on a position touched before a certain time T1 from the key press, for example, about 100 ms.

  If a touch to a touch area smaller than the key area is touched near the boundary of the area, the touch position may be shifted during the pressing operation, and an unexpected function may be activated. According to this input terminal, since the touch area a predetermined time before the key is pressed is used for determining the function selection in combination with the key press, even if the touch position is shifted by the pressing operation, the operator can The function of the recognized touch area can be selected. The fixed time T1 is based on the time when the actual pressing event occurs after confirming the function of the touch area on the display screen, and is assumed to be about several tens to 100 ms.

  The second feature of the present invention is that (a) a key input means that has a key area and detects that the key area is pressed, and (b) at least one key area is divided into a plurality of touch areas. Touch detection means for detecting that the touch area is touched, and (c) a character area or a function corresponding to the key area detected by the key input means or the touch area detected by the touch detection means. An input terminal comprising: an output means; and (d) an input function determination means for selecting a character or a function corresponding to the touch area in accordance with the contact position detected by the touch detection means when the key input means detects a key press completion. It is a summary.

  That is, the touch detection means is attached to the keypad, and the touch area is managed in a sub key area divided into a key area and a plurality of functional areas related to one key. When a certain key area is touched, the operator is notified that the key has been touched by highlighting or reversing the display frame.When the key is pressed, a plurality of functions assigned to the key are displayed. The operator is notified of which sub-key area is touched by highlighting or reversing the display frame. The display of a plurality of functions assigned to a key may be performed when the key is touched. When the completion of pressing is detected, or when the touch OFF following the completion of pressing is detected, the function assigned to the subkey area touched immediately before is operated.

  According to the input terminal according to the second feature, touch detection means whose touch position detection resolution is smaller than the size of the key area is attached to the keypad, and when a certain key is pressed and the pressing is completed, the touch position is detected. Then, a plurality of function settings and selections can be made with one key depending on which of the sub-key areas set in the key area is touched. In particular, the effect is high with five touch inputs in which five hiragana characters are arranged in one key.

  The input terminal according to the second feature further includes touch area storage means for storing the touch area detected by the touch detection means and the time when the contact is detected, and the object is divided into a plurality of touch areas. When the key area is pressed, the input function determining means refers to the touch area stored in the touch storage means and the time, and determines the touch area touched a predetermined time before the time when the key press completion is detected. The character or function corresponding to the touch area may be selected.

  That is, a subkey area for determining a function is determined based on a position touched a predetermined time T2 before, for example, about 100 ms before detection of completion of key depression or detection of touch OFF subsequent to completion of key depression.

  If a touch to a touch area smaller than the key area is touched near the boundary of the area, the touch position may be shifted during the pressing operation, and an unexpected function may be activated. According to this input terminal, the touch area a certain time before the key press is used in combination with the key press for determination of function selection. Therefore, even if the touch position is shifted due to the press operation, the operator can The function of the touch area recognized can be selected. The fixed time T2 is based on the time when the actual pressing completion event occurs after confirming the function of the touch area on the display screen or the like, and is assumed to be several tens to 100 ms.
