Description

  The present invention relates to a portable terminal device having a display unit with a touch panel.

  Conventionally, cellular phones, PDAs, and other portable terminal devices have become more and more multifunctional, and the miniaturization of devices has greatly improved. For this reason, the operation unit has been downsized and the display unit has been downsized. The current situation is that the display is remarkably difficult to see and the operation is difficult.

  On the other hand, as a method for solving such a problem, a portable terminal device having a display unit with a touch panel is also known. However, in many cases, this type of display has to be operated with a touch pen prepared in advance, and the display is still difficult to see and difficult to operate.

  In various input devices that use a touch panel for the display unit, the characters and numbers that can be entered and displayed on the display unit are enlarged and displayed as appropriate so that input can be performed easily and correctly. Are also known. (For example, see Patent Documents 1 and 2)

According to this, even if you touch a position that is different from the displayed character or number, if the touched position is close to the character or number, the character near the touched position will be the center. If you move a hand or pen close to a predetermined distance on the touch panel, the display at that position will be enlarged, and the enlarged display will be displayed. Based on this, it is possible to easily and accurately input desired characters and numbers with a hand or a pen.

  However, in Patent Document 1, when a position different from a displayed character or number is touched, the display of the portion is enlarged, and the displayed character or number is directly touched. In such a case, the display is not enlarged. That is, what is described in this patent document is that the characters and numbers that were originally displayed cannot be touched by chance, and they are enlarged when touched at different positions. For large ones. Therefore, in this case, when the originally displayed character or number is small, the character or number is directly touched, and there is a problem that enlargement display is not performed and input is still very troublesome.

  In addition, in the device described in Patent Document 2, the display of the portion is enlarged and displayed only by bringing a hand or a pen close to the touch panel. There is a problem that it is very difficult to operate as it is.

  In either case, after the enlarged display, how to input is not specified, and the enlargement is only enlarged once at a certain enlargement ratio, and the user can arbitrarily It is not possible to enlarge and display up to the enlargement ratio.

  The present invention has been made in view of such a conventional problem, and provides a portable terminal device that can be easily and accurately operated with a finger or the like, despite the downsizing of devices.

  FIG. 2 is a block diagram showing a schematic configuration of the mobile terminal device according to the embodiment of the present invention.

  In addition to the display unit 2 with the touch panel function described above, the mobile terminal device according to the embodiment of the present invention includes a wireless transmission / reception unit 21, a camera unit 22, and an e-mail storage unit 23 for making calls and e-mails. A voice input / output unit 24, a microphone 25, a receiver 26, a call signal output unit 27, a speaker 28 for ringing tone output, a light emitting diode 29, a vibrator 30, an operation unit 31, and a control unit 32 for controlling them. ing.

  Next, the operation of the mobile terminal device according to the embodiment of the present invention will be described.

  First, the mobile terminal device according to an embodiment of the present invention is configured to perform most operations on the display unit 2.

  As shown in FIG. 1, when the mobile terminal device is set to the telephone mode by touching the display of “Menu”, the numeric keypad 3 is displayed in the first area A. Touch the numeric keypad 3 to input the telephone number of the other party, display it on the display unit 8, and touch the predetermined dialing operation such as “dial” display in that state. The telephone number inputted in this way can be transmitted and transmitted to a telephone base station (not shown) through the wireless transmission / reception unit 21. If the other party responds to the outgoing call, a call circuit is formed with the other party via the wireless transmission / reception unit 21, and the voice input / output unit 24 and the wireless transmission / reception unit 21 are connected using the microphone 25 and the receiver 26. The other party can make a call with each other.

  When there is a telephone call from the other party and the call is received by the radio transmission / reception unit 21, the ringing tone output unit 27 applies predetermined signals to the speaker 28, the light emitting diode 29, the vibrator 30, and the like under control of the control unit 32. These signals are output, and these are driven and called. If a predetermined operation is performed in response to the call, a call can be made with the other party.

  In the case of an e-mail, the e-mail mode is set by touching the display of “Menu”, and at that time, an e-mail text is created based on the display displayed in the first area A of the display unit 2 and transmitted. Then, the created electronic mail can be transmitted to the other party via the wireless transmission / reception unit 21, and the created electronic mail is stored in the electronic mail storage unit 23 under the control of the control unit 32.

  If there is an e-mail from the other party, the e-mail is received by the wireless transmission / reception unit 21 and stored in the e-mail storage unit 23, and a predetermined call signal is output to the call signal output unit 27, and the speaker 28, light emitting diode 29, vibrator 30 and the like are driven to notify that an e-mail has been received.

  By the way, in the portable terminal device according to the present embodiment, each of the areas A to C provided in the display unit 2 is brought into contact with each other, and each operation is performed according to the operated position and the operation state. Performs different operations as shown in FIG.

  First, the control unit 32 constantly monitors whether a touch pen, a finger, or the like has touched the screen of the display unit 2. When a touch pen, a finger, or the like touches the screen (S301), it is first determined whether the contacted area is the first area A or the second area B (S302). If the contacted area is the first area A (Y in S302), it is determined whether or not the contact has been made continuously for a predetermined time (predetermined time T1) (S303). If it is determined that contact has been made for a predetermined time T1 or longer (Y in S303), the display of the first area A is enlarged and displayed around the contacted position (S304). For example, if the touched position is in the vicinity of “2”, the vicinity of “2” is enlarged and displayed on the entire surface of the first region A as shown in FIG.

  If the contact is released (Y in S305), it is then determined whether or not a predetermined time (predetermined time T3) has elapsed (S306). In a state where the predetermined time T3 has not elapsed (N in S306), In this state, it waits for the next contact as it is (S308), and when the predetermined time T3 elapses, it returns to the original display, that is, the original display that has not been enlarged (S307), and waits for the next contact. (S308).

  If the contact is continued for a predetermined time (predetermined time T2) without releasing the contact (N in S305), the display is enlarged again (S304). For example, even if the display is enlarged as shown in FIG. 4, it is further enlarged and displayed as shown in FIG. The display enlargement is repeated many times until the contact is released, and is continued until a predetermined fixed enlargement ratio (maximum enlargement ratio) is reached.

  That is, in step 309, not only is it determined whether or not the contact has been continuously performed for a predetermined time T2 or more, but it is also determined whether or not the enlargement ratio is equal to or less than a predetermined maximum enlargement ratio. Therefore, when the enlargement ratio reaches a predetermined maximum enlargement ratio, the display enlargement is forcibly stopped. That is, when the enlargement ratio reaches a predetermined maximum enlargement ratio even after the predetermined time T2 has elapsed (N in S309), it is in a state of merely determining whether or not to release the contact in that state (S305). In this state, the enlarged display (S304) of the first area A is not performed.

  Even when the first region A is touched (Y in S302), the contact is released in a state where the contact time does not reach a predetermined time (predetermined time T1) (N in S303) (S310). In (Y), the information on the touched position is determined as it is under the control of the control unit 32, is input to a predetermined memory or the like (not shown) (S311), and is displayed on the display unit 8.

  For example, in the state of FIG. 1, when “1” is touched and the contact is released before a predetermined time (predetermined time T1) elapses, the information of the touched “1” Based on the control of the control unit 32, “1” is displayed on the display unit 8 as shown in FIG. 1. Then, as shown in FIG. 4, even when the “2” is touched in the enlarged display state and the contact is released before the predetermined time T1 elapses, the information on the touched “2” is displayed. Is determined under the control of the control unit 32, and “2” is displayed on the display unit 8 as shown in FIG.

  That is, regardless of whether or not the display of the first area A is enlarged, the display touches any display of the first area A in that state, and a predetermined time (predetermined time T1) is reached. If the contact is released before the elapse of time (that is, if the button is pressed for a short time), the information of the display pressed for a short time is determined as it is under the control of the control unit 32 and displayed on the display unit 8. . Thereafter, the display returns to the original display, that is, the display that has not been enlarged (S307), and waits for the next contact (S308). Therefore, for example, in the state of waiting for the next contact, if “1”, “2”, and “3” are sequentially pressed shortly, “123” is displayed on the display unit 8.

  Even when the screen is touched (S301), if the touched position is not the first area A but the second area B (N in S302), the touched position is first slid. Whether or not is determined based on the control of the control unit 32 (S312). If it is determined that the slide has been made (Y in S312), the display of the first area A is slid in the direction opposite to the slide direction under the control of the control unit 32 (S313). When the contact is released (Y in S314), the display of the first area A is maintained as it is, and until a predetermined time (predetermined time T3) has elapsed (N in S306), the next contact is awaited. (S308). When a predetermined time (predetermined time T3) elapses (Y in S306), the display of the first area A returns to the original state, that is, the normal state that is not enlarged and not slid. (S307), and then waits for the next contact (S308).

  For example, as shown in FIG. 4, in an enlarged display state, numbers such as “1”, “4”, and “7” cannot be seen, but contact the second area B (N in S302), and the direction of the arrow When it is slid (Y in S312), the display of the first area A moves in the direction opposite to the arrow, and as shown in FIG. 6, numbers such as “1”, “4”, and “7” are visible. . Similarly, as shown in FIG. 5, in the case of an enlarged display, in addition to numbers such as “1”, “4”, and “7”, numbers such as “8” and “9” can be seen. When the second area B is touched in the state (N in S302) and slides in the direction of the arrow (Y in S312), the display of the first area A moves in the direction opposite to the arrow, as shown in FIG. Then, the numbers “8” and “9” can be seen.

  Accordingly, the first area A is contacted for a predetermined time (predetermined time T1) for a predetermined time (S303), and the display of the first area A is enlarged (S304). Next, even if it disappears, by touching the second region B (N in S302) and sliding in the direction of the arrow (Y in S312), the number (display) to be operated can be easily In this state, the user touches the number (display) to be operated (Y in S302) and releases the contact within a predetermined time (predetermined time) (S310). Y) The content of the touched number (display) can be confirmed and input (S311).

  If the contacted area is the second area B (N in S302) and does not slide as it is (N in S312) and a predetermined time (predetermined time T1) has elapsed (Y in S315), the control is performed. Under the control of the unit 32, the display of the first area A is reduced and displayed at the center of the first area A (S316). Even if the display of the first area A is reduced (S316), if the contact is not released thereafter (N in S317), then whether or not a predetermined time (predetermined time T2) has passed has passed. Is determined (S318), and when a predetermined time (predetermined time T2) has elapsed (Y in S318), the previously reduced display is further reduced (S316). For example, as shown in FIG. 5, in the case of an enlarged screen, the screen is reduced as shown in FIG. 4 and further reduced in the direction shown in FIG. This state is repeated until the reduction ratio reaches a predetermined minimum reduction ratio unless the contact of the second region B is released.

  That is, in step 318, not only is it determined whether or not the contact has been continuously performed for a predetermined time T2 or more, but it is also determined whether or not the reduction rate is equal to or greater than a predetermined minimum reduction rate. When the reduction ratio reaches a predetermined minimum enlargement ratio, the display reduction is forcibly stopped. Therefore, even when the predetermined time T2 has elapsed, when the reduction rate reaches the predetermined minimum reduction rate (N in S318), the reduction of the first area A (S316) is not repeated, and the contact is exclusively released. It is in a state of merely determining whether or not to perform (S317).

  If the contact is released (Y in S317), the next contact is waited in that state (S308), and if the predetermined time (predetermined time T3) has passed, the original state, that is, the enlargement is also performed. Then, it returns to the original state that has not been reduced (S307) and waits for the next contact (S308).

  Touch the second region B (N in S302), do not slide as it is (N in S312), and do not reach a predetermined time (predetermined time T1) (N in S315) Is canceled (Y in S319), the state immediately waits for the next contact (S308), and if the predetermined time (predetermined time T3) has passed, the original state, that is, the enlargement and the reduction are performed. It returns to the original state that has not been made (307) and waits for the next contact (S308).

  Thus, according to the present embodiment, if the first area A is touched and the contact is released (short press) within a predetermined time (predetermined time T1), the touched number, display, etc. Is confirmed and entered. If the contact is continued (long press) beyond a predetermined time (predetermined time T1), the display of the first area A is enlarged and displayed centering on the contacted number and display. And as long as it is in continuous contact, it is repeatedly repeated until it reaches the maximum magnification. Therefore, even if the original number or display is too small and difficult to input correctly, the user enlarges to an easy-to-use enlargement ratio, releases the contact in that state, and then presses briefly to The number and the display can be enlarged and input, and it is possible to input easily with a finger or the like without using a touch pen or the like.

  In addition, according to the present embodiment, the display of the first area A can be slid by touching and sliding on the second area B, so an attempt is made to input to the first area A. Even when numbers and displays do not appear, it is possible to make the numbers and displays that do not appear in the first area A simply by touching and sliding on the second area B, and therefore input in this state. You can easily enter the number and display you want to press. In particular, when the display of the first area A is enlarged, it is often considered that some or all of the numbers and displays to be used will not be visible if a long press is performed before the enlarged display. However, according to the present embodiment, the display of the first area A can be slid by touching and sliding the second area B even after the first area A is enlarged and displayed. The lost display can be easily seen.

  According to the present embodiment, the direction in which the second region B is touched and slid and the direction in which the display of the first region A slides when the second region B is touched are opposite to each other. Therefore, if you want to display the numbers and display hidden on the first area A, the numbers and display hidden to the right of the first area A slide in the second area B. When the user wants to display, it is only necessary to slide in a direction that is very easy to understand, such as sliding rightward in the second region B, which is very convenient for the user.

  In addition, according to the present embodiment, if the second region B is pressed for a long time, the first region A once enlarged and displayed can be arbitrarily reduced and sequentially displayed. The display of the first area A can be enlarged to a desired size while being arbitrarily enlarged or reduced by using the second area B and the second area B.

  Further, according to the present embodiment, even after the contact with the first region A or the second region B is released, the state immediately waits for the next contact in this state, but a predetermined time ( When the predetermined time T3) has elapsed, even if the display has been enlarged, reduced, or slid so far, all of these are automatically returned to the original display, and in this state, the next contact is awaited. Therefore, if the contact is released and left unattended, it automatically returns to the original state and does not require an operation for returning each time.

  In the present embodiment, it is desirable that the predetermined constant times (predetermined times T1, T2, T3) have a relationship of T3> T1> T2. In this way, for example, if the contact is continued for 2 seconds, enlargement or reduction is started. If the contact is continued thereafter, the enlargement / reduction is repeated every second. When the contact is released, it can be said that it returns to the original display if it is left for 5 seconds or more or 10 seconds or more after the contact is released. Can be.

  In this embodiment, the predetermined time T1 is measured in steps 303 and 315, and the predetermined time T2 is measured in steps 309 and 318. However, in steps 303 and 315, the predetermined times T11 and T12 are respectively measured. It goes without saying that the predetermined times measured in each step may be different from each other so that the predetermined times T21 and T22 are continued at 309 and 318, respectively.

  In the present embodiment, a predetermined time (predetermined times T1, T2, T3, or T11, T12, T21, T22, T3) can be arbitrarily set and registered in addition to the default value. It is desirable to keep it. In this way, the user can arbitrarily set and use a predetermined time that is most easily used.

  In the present embodiment, as described above, not only a telephone but also an email and the Internet are possible. For example, when inputting Chinese characters in an email or the Internet, the number of strokes A large number of Chinese characters stored for each are displayed in a list in the first area A, and any Chinese character can be touched and input from the list.

  In FIG. 8, the display of “Menu” is operated to enter the e-mail mode, and in this state, a large number of kanji stored for each number of strokes (here, three kanji characters) are listed in the first area A. The displayed state is shown. In such a case, since the number of Chinese characters originally exceeds that of numbers, the display area allocated to one Chinese character is inevitably smaller than that of numbers. Therefore, even if the first region A is touched in the state of FIG. 8, it can only touch the approximate position unless a special touch pen or the like is used. Therefore, in this state, the desired Chinese character is touched accurately. It is very difficult. However, according to the present embodiment, in the state shown in FIG. 8, a finger or the like is contacted in the vicinity of the desired kanji, and the state shown in FIG. 10, the state of FIG. 10, and the state of FIG. 11 can be enlarged and displayed in sequence, and at the stage of being arbitrarily enlarged and displayed, the desired kanji can be specified accurately and contacted. It becomes possible. Of course, in this case as well, the display of the first area A can be slid or reduced, and these operations can be used arbitrarily to display the desired kanji and short-press the kanji. It is possible to confirm and input.

  8 is a state in which “lower” is short-pressed among the displayed kanji characters, FIG. 9 is a state in which the region A is long-pressed to enlarge the display of the region A, FIG. 10 is further enlarged, FIG. 11 shows a state in which “three” is pressed for a short time, and FIG. 11 shows a state in which the display is further enlarged and “circle” is pressed for a short time.

  Furthermore, in the present embodiment, video captured by the camera unit 22, video received by e-mail, and the like can be similarly enlarged, reduced, or slid and displayed.

  FIG. 12 shows a state in which “Shimosanmaru” is input as shown in FIG. 11 and a video image captured by the camera unit 22 and a video image received by e-mail are displayed in the first area A. ing. In FIG. 12, when an arbitrary position (here, almost the central portion) of region A is touched and a predetermined time or more has passed in that state, the state of FIG. 12 is enlarged and displayed in the state of FIG. 13. When the second area B is touched and slid, the display of the first area A slides in the direction opposite to the sliding direction, and when the same position is touched for a predetermined time or longer without sliding, the display is reduced. This is the same as in the case of numbers and characters so far.

  As described above, in the present embodiment, not only numbers, but also kanji characters, images, and the like, all the displays displayed in the first area A are enlarged or reduced in the same manner as numbers. It is configured to be able to slide. Therefore, these displays can be arbitrarily enlarged, reduced, and slid to select a desired display accurately, touch, and information on the display can be input.

  In the present embodiment, it is described in terms of “contact”, such as contacting the display unit 2 and maintaining the state for a predetermined period of time or releasing the contact before that. In the present invention, it is necessary to note that “contact” is used as a substantially synonym for “pressing operation” because it does not change that the display unit is pressed with a predetermined force or more.

  In the present embodiment, the case where the display unit is continuously touched for a predetermined time or longer is described as a long press, and the case where it is not a short press is described. Then, it may be possible to include these operations by taking into account the operations that are said to be performed or by changing to operations that are strongly pressed. In this way, for example, the display unit is pressed with a relatively weak force, and the state is continuously displayed for a predetermined time or more to enlarge the display. Then, it is possible to strongly press the enlarged display, and to confirm and input information corresponding to the pressed display, which makes it easier to input more intuitively.

  In the present embodiment, the second region B is formed in a link shape on the entire outer periphery including the first and third regions A and C. However, the second region B includes the first and third regions, respectively. It may be provided only in one of the left and right and upper and lower sides of the regions A and C, or may be provided in different positions. In addition, the second area B is not provided with any display of characters, numbers, etc. However, if the second area B is operated on the second area B, the display of the area A as described above is performed. Needless to say, it is possible to provide a display that guides the user to slide or reduce the display, or to display another design pattern or the like.

  The present invention has an effect that can be easily and accurately operated with a finger or the like in spite of downsizing of the device, and is useful for a portable terminal device or the like.
