Description

  The present invention relates to a portable terminal including a pointing device that receives an input based on a moving distance of a contact object such as a touch screen or a touch pad.

  The portable terminal is equipped with various input devices for receiving operation instructions from the user. In particular, in recent years, a lot of pointing devices that can perform input by touching an operation surface such as a touch screen or a touch pad with a finger or the like have been mounted on mobile terminals. This touch screen or the like receives an operation instruction based on input information obtained by sensing a change in capacitance or contact pressure associated with contact with the operation surface, and inputs the operation instruction with an intuitive operation. be able to.

  One process in which a portable terminal receives an instruction using an input device is a scroll process. The scroll process is, for example, a process in which when all of the display content displayed on the display cannot be displayed in the display, the content is moved left and right and up and down to display (see, for example, Patent Document 1).

  One method of receiving an instruction to execute the scroll process on the touch screen is a method using a moving operation performed with a contact object such as a finger on the operation surface. In this method, a moving distance obtained from a moving operation of a finger or the like is received as an operation amount of scroll processing. Specifically, when a touch screen or the like detects a movement operation at a predetermined distance as a reference, a method of receiving an instruction to execute one scroll process (for example, scroll display for one line of display contents) is received.

JP 2008-181248 A

  One of the input devices is an operation key that receives an operation instruction when pressed. When the user inputs an operation instruction using the operation key, the user can easily perform an input for executing a scroll process or the like once with the click feeling obtained when the operation key is pressed. For example, in order to move the display content on the display by one line, it is only necessary to press an operation key such as a cross key once, and the user can easily determine that one input has been performed. .

  However, unlike the operation keys described above, the touch screen or the like is difficult to determine the moving distance of the moving operation necessary for executing the scrolling process once. For this reason, there has been a problem that the movement distance is insufficient and the execution instruction of the scroll process is not detected as an input, or the movement distance is too large and the predetermined process is performed more than necessary.

  Moreover, the size of a touch screen is limited from the viewpoint of miniaturization. When the user wants to input a large scroll operation amount, the user has to perform a moving operation of moving the finger up and down or left and right on a small touch screen many times.

  From the above viewpoint, the instruction input to the scroll processing based on the moving distance of the moving operation on the touch screen is a factor that makes the user feel poor operability.

  The present invention has been made in consideration of such circumstances, and improves the operability of the instruction input based on the moving operation of the contact object by suitably changing the determination moving distance as the input unit of the moving operation. An object of the present invention is to provide a portable terminal that can be used.

  In order to solve the above-described problem, a mobile terminal according to the present invention includes an input unit that receives an input by detecting a moving operation of a contact object with respect to an operation surface having a predetermined area, and the movement detected by the input unit A distance detection unit that detects that the operation has moved the determination movement distance that is the first distance, and a process execution that executes a predetermined process when the movement operation of the determination movement distance is detected by the distance detection unit And a changing unit that changes the determination movement distance to a distance different from the first distance when a predetermined condition is satisfied.

  The portable terminal which concerns on this invention can improve the operativity of the instruction | indication input based on the movement operation | movement of a contact thing by changing suitably the determination movement distance as an input unit of movement operation | movement.

  An embodiment of a portable terminal according to the present invention will be described with reference to the accompanying drawings. As a mobile terminal to which the present invention is applied, a slide type mobile terminal in which a plurality of housings are slidably coupled will be described as an example.

  1A is an external configuration diagram illustrating a closed state of the mobile terminal 1, FIG. 1B is an external configuration diagram illustrating an open state of the mobile terminal 1, and FIG. It is an external appearance block diagram which shows the state opened horizontally.

  The mobile terminal 1 includes a rectangular plate-shaped upper housing 10 and a lower housing 11 having substantially the same shape as the upper housing 10. In the closed state shown in FIG. 1A, the portable terminal 1 is laminated so that the upper casing 10 and the lower casing 11 cover one surface of each other. The upper casing 10 and the lower casing 11 in the closed state are slidable by a predetermined length in a predetermined direction. The mobile terminal 1 is deformed from the closed state to the open state shown in FIGS. 1B and 1C by relatively sliding the upper housing 10 and the lower housing 11.

  The upper housing 10 is provided with a touch screen 12, a receiver 13, and a microphone 14. The touch screen 12, the receiver 13, and the microphone 14 are provided so as to be exposed to the outside regardless of whether the portable terminal 1 is closed or opened.

  The touch screen 12 displays display data including characters, images, and the like, and accepts an input by detecting a moving operation of the contact object. The touch screen 12 is formed by, for example, arranging a plurality of elements for detecting contact on the surface on a display, and further laminating a transparent screen thereon. As a method for detecting the movement of the contact object on the touch screen 12, a pressure-sensitive method for detecting a change in pressure, an electrostatic method for detecting an electric signal due to static electricity, or the like is applied. The display of the touch screen 12 includes, for example, an LCD (Liquid Crystal Display) or an organic EL (Electro-Luminescence) display.

  Note that the area for receiving input by detecting the movement of the contact object on the touch screen 12 does not have to be the entire area, and may be provided in part.

  When the portable terminal 1 is in the vertically long state (FIG. 1B), the display content configured in the vertically long direction is displayed on the touch screen 12. On the other hand, when the mobile terminal 1 is in the horizontally long state (FIG. 1C), the display content configured in the horizontally long state is displayed on the touch screen 12.

  An operation key 15 is arranged on the surface of the lower housing 11 exposed when the mobile terminal 1 is in an open state. The operation keys 15 have a plurality of keys for inputting instructions when pressed by the user. The mobile terminal 1 has a key arrangement of the operation keys 15 arranged in 3 rows × 15 columns excluding the direction key 16 and the four soft keys 17a, 17b, 17c, and 17d (soft keys 17) depending on the posture of the mobile terminal 1. The mode (key layout mode) is switched.

  When the portable terminal 1 is in a vertically long state (FIG. 1B), a numeric keypad mode that is a key layout mode for accepting input with the operation keys 15 arranged in the numeric keypad functions. In the numeric keypad mode, the operation keys 15 are numeric keys that accept input of numbers from “0” to “9”, “#” key, “*” key, “send” key, “end call” key, “clear” key Function as.

  When the portable terminal 1 is in the horizontally long state (FIG. 1C), the QWERTY key arrangement mode, which is a key arrangement mode for accepting input with the operation keys 15 arranged in the QWERTY key arrangement, functions. In the QWERTY key arrangement mode, the operation keys 15 mainly function as alphabet keys that accept input of alphabets “A” to “Z”, “Shift” key, and “Fn (function)” key. Further, the operation key 15 is combined with the input of the alphabet, the numeric key for accepting the input of the numbers “0” to “9” by combining with the pressing of the Fn key, and “@”, “.”, “()”, It functions as a symbol key that accepts input of symbols such as “!” And “?”.

  The operation key 15 is made of, for example, a transparent or translucent resin, and includes a lighting device (key light) on the back surface thereof. This key light is prepared for each key arrangement mode. The mobile terminal 1 presents character symbols that can be input to the user by changing the key light used in accordance with the change in the key arrangement mode.

  The operation key 15 is also provided with a direction key 16 and a soft key 17 that are used regardless of the numeric keypad layout and the QWERTY layout. The direction key 16 is a key for inputting up, down, left, and right directions. The soft key 17 is a key for accepting a necessary instruction according to an application executed on the mobile terminal 1. For example, an instruction to activate an application such as an address book, e-mail software, or an Internet browser, or activation of a submenu. Various instructions such as symbols, pictograms, and space insertion instructions are accepted.

  Note that the user can input via the operation key 15 exposed to the outside when the portable terminal 1 is open, but cannot input via the operation key 15 when the mobile terminal 1 is closed.

  FIG. 2 is a schematic functional block diagram showing a main functional configuration of the mobile terminal 1 in the present embodiment.

  In the portable terminal 1, the main control unit 30, the power supply circuit unit 31, the input control unit 32, the display control unit 34, the voice control unit 36, the communication control unit 37, the storage unit 39, and the acceleration sensor 40 can communicate with each other via a bus. Connected to and configured.

  The main control unit 30 includes a CPU (Central Processing Unit). The main control unit 30 operates based on various programs stored in the storage unit 39 and performs overall control of the mobile terminal 1. Further, the main control unit 30 performs a determination movement distance change process, which will be described later, and other various calculation processes and control processes.

  The power supply circuit unit 31 includes a power supply source (not shown). The power supply circuit unit 31 switches the power supply ON / OFF state of the mobile terminal 1 based on an operation of turning on the power supply. The power supply circuit unit 31 supplies power from the power supply source to each unit when the power supply is in an ON state, thereby enabling the mobile terminal 1 to operate.

  The input control unit 32 includes an input interface for the operation keys 15 and the touch screen 12. When the input control unit 32 detects that the operation key 15 and the touch screen 12 have received the input, the input control unit 32 generates a signal indicating the input and transmits the signal to the main control unit 30. Further, the input control unit 32 receives the detection signal from the touch screen 12 as position information indicating the coordinates of the input position every predetermined time, generates a signal indicating the input, and transmits the signal to the main control unit 30.

  The display control unit 34 includes a display interface for the touch screen 12. The display control unit 34 displays an image based on the document data and the image signal on the touch screen 12 based on the control of the main control unit 30.

  The voice control unit 36 generates an analog voice signal from the voice collected by the microphone 14 based on the control of the main control unit 30 and converts the analog voice signal into a digital voice signal. Further, when acquiring the digital audio signal, the audio control unit 36 converts the digital audio signal into an analog audio signal based on the control of the main control unit 30 and outputs the analog audio signal as audio from the receiver 13.

  Based on the control of the main control unit 30, the communication control unit 37 restores data by performing a spectrum despreading process on the received signal received from the base station via the antenna 38. This data is transmitted to the voice control unit 36 and output from the receiver 13 according to an instruction from the main control unit 30, transmitted to the display control unit 34, displayed on the touch screen 12, or recorded in the storage unit 39. To do. In addition, the communication control unit 37 controls the voice data collected by the microphone 14 based on the control of the main control unit 30, the data input via the operation keys 15 and the touch screen 12, and the data stored in the storage unit 39. Is obtained, a spread spectrum process is performed on these data, and the data is transmitted to the base station via the antenna 38.

  The storage unit 39 is a ROM (Read Only Memory) that stores a processing program for processing performed by the main control unit 30 and data necessary for the processing, a hard disk, a non-volatile memory, a database, and is used when the main control unit 30 performs processing. RAM (Random Access Memory) that temporarily stores data to be stored.

  The acceleration sensor 40 acquires the detected acceleration (for example, acceleration applied to each of the three axial directions) based on the control of the main control unit 30 or at every elapse of a certain time. The detected acceleration generates a signal indicating the detected value and is transmitted to the main control unit 30. The main control unit 30 that has received the signal determines the attitude of the mobile terminal 1 based on the acceleration given to the mobile terminal 1. The mobile terminal 1 sets the display direction of the screen of the touch screen 12 according to this posture, or sets the key arrangement mode of the operation keys 15.

  The portable terminal 1 according to the present embodiment can accept an instruction for an image displayed on the touch screen 12 as described above by detecting the movement operation of the contact object with respect to the operation surface. The user inputs to the touch screen 12 via the user's finger or the like as a contact object. In the present embodiment, an example in which input is mainly performed on the touch screen 12 with a finger as a contact object will be described. However, a contact object other than a finger can be similarly applied.

  FIG. 3 is a diagram conceptually illustrating how the touch screen 12 accepts an instruction input for executing a predetermined process.

  Note that the operation surface capable of detecting the movement operation on the touch screen 12 is configured by, for example, 750 dots × 480 dots. The predetermined process based on the moving operation detected on the touch screen 12 will be described as a scroll process of a predetermined amount (for example, one line) of display contents. In this scroll process, the posture of the touch screen 12 is shown in a vertically long state, but the same process is performed even in a horizontally long state. Moreover, although the movement operation | movement of the up-down direction on the touch screen 12 is shown, even when the movement operation | movement of the left-right direction is performed, it is the same.

  The portable terminal 1 is configured to accept an instruction input for executing the scroll process once by detecting a movement operation of the determined movement distance. The “determination moving distance” is a distance of a moving operation necessary for receiving an instruction input for one scroll process. The instruction input received via the touch screen 12 corresponds to an instruction input received when the direction key 16 of the operation key 15 is pressed once, for example.

  For example, as illustrated in FIG. 3, the mobile terminal 1 executes the scroll process once when a movement operation of the determination movement distance 50 dots is detected from the movement operation of the finger F received from the point A on the touch screen 12. Further, when the determination moving distance 50 dots is detected, the scroll process is executed once. When a total of 150 dots of movement is detected in the movement of the finger F to the point B, the mobile terminal 1 executes scroll processing for three times.

  The mobile terminal 1 in the present embodiment is configured to further improve user operability by changing the determination movement distance under a predetermined condition. Hereinafter, the first to fifth determination movement distance changing processes will be described. It is assumed that a default value (for example, 50 dots) as the first distance is set as the determination movement distance at the start of the first to fifth determination movement distance changing processes.

  FIG. 4 is a flowchart illustrating a first determination movement distance change process executed by the main control unit 30 of the mobile terminal 1 in the present embodiment. This first determination movement distance changing process is an effective process for the movement operation when the user inputs a scroll process instruction input only once (or a small number of times).

  In step S <b> 11, the main control unit 30 determines whether or not detection of a finger movement operation on the touch screen 12 is started based on whether or not a detection signal is transmitted from the input control unit 32. When it is determined that the detection of the movement operation has not started (NO in step S11), the main control unit 30 waits until the detection of the movement operation is started.

  On the other hand, if the main control unit 30 determines that the detection of the movement operation has started (YES in step S11), in step S12, after the detection of the movement operation starts, the first detection of the instruction input for executing the scroll process The determination movement distance used for the is changed. The main control unit 30 changes the determination movement distance from the default value to a distance larger than the default value as the second distance. Along with this, the movement operation for inputting an instruction to execute the scroll process once requires an operation of a larger distance than the normal time in which the default value is set.

  In step S <b> 13, the main control unit 30 determines whether or not an instruction input for one scroll process has been detected by detecting a movement operation of the determined movement distance on the touch screen 12. If the main control unit 30 determines that an instruction input for one time has not yet been detected (NO in step S13), the main control unit 30 waits until a moving operation is detected.

  On the other hand, if the main control unit 30 determines that an instruction input for one scroll process has been detected (YES in step S13), the main control unit 30 again changes the determination moving distance to the default value in step S14. Accordingly, after the start of detection of the movement operation, a determination moving distance larger than the default value is required for the first scroll processing instruction input, and the second and subsequent scroll processing instruction input is smaller than the first time. A default determination travel distance is required.

That is, the determination moving distance f (n) (number of scroll processing instruction inputs n = 1, 2, 3,...) Is

  FIG. 5 is a diagram conceptually illustrating how the touch screen 12 receives an instruction input when the first determination movement distance changing process is executed.

The main control unit 30, the moving operation based on the instruction input of the finger F initiated at point A ₁ by the user (instruction input scroll operation for first time) applied a 100dot as determined travel distance. The mobile terminal 1 is a point B ₁ on the instruction input of the two-time scrolling process that starts applying the 50dot the default value as determined travel distance.

  For the user who wants to input an instruction input for one scroll process, the mobile terminal 1 increases the determination movement distance applied to the first scroll process instruction input by the first determination movement distance change process. The operability can be improved.

  That is, it can be said that it is difficult to sense the speed of the moving operation immediately after the user starts the moving operation. For this reason, the moving operation immediately after the start of the moving operation has a high speed and is too larger than the determination moving distance, and there is a possibility that the instruction input for the scroll process is performed not only once but twice. On the other hand, by increasing the determination movement distance immediately after the start of the movement operation, the mobile terminal 1 easily performs the movement operation of the determination movement distance even when the movement distance of the user movement operation becomes too large. be able to.

  Next, the second determination moving distance changing process executed on the mobile terminal 1 will be described.

FIG. 6 is a flowchart illustrating the second determination movement distance changing process executed by the main control unit 30 of the mobile terminal 1 in the present embodiment. This second determination movement distance changing process is similar to the first determination movement distance changing process of FIG. 4 in relation to the movement operation when the user inputs an instruction for scroll processing only once (or a small number of times). Step S21, which is an effective process, is substantially the same as the start determination step S11 of the first determination movement distance change process in FIG.

  If the main control unit 30 determines that the detection of the moving operation has started (YES in step S21), the main control unit 30 uses it for the first detection of the instruction input for executing the scroll process after the detection of the moving operation in step S22. Change the determination movement distance. The main control unit 30 changes the determination movement distance from the default value to a distance smaller than the default value as the second distance. Along with this, the movement operation for inputting an instruction to execute the scroll process once requires an operation of a small distance compared to the normal time when the default value is set.

  Step S23 is substantially the same as the instruction input detection determination step S13 of the first determination movement distance change process in FIG.

  When it is determined that the instruction input for one scroll process is detected (YES in step S23), the main control unit 30 performs the second instruction input for executing the scroll process after the start of the movement operation detection in step S24. The determination moving distance used for detection is changed. The main control unit 30 changes the determination movement distance from the default value to a distance larger than the default value as the third distance. Along with this, the movement operation for inputting an instruction to execute the scroll process once requires an operation of a larger distance than the normal time in which the default value is set.

  Step S25 is substantially the same as the instruction input detection determination step S13 of the first determination movement distance changing process in FIG.

  When it is determined that the instruction input for one scroll process is detected (YES in step S25), the main control unit 30 changes the determination moving distance to the default value again in step S26. Along with this, after the start of detection of the movement operation, a determination movement distance smaller than the default value is required for the first scroll processing instruction input, and a determination movement larger than the default value is required for the second scroll processing instruction input. A distance is required, and a determination moving distance of a default value is required for an instruction input for at least the third scroll process.

That is, the determination moving distance f (n) is

  FIG. 7 is a diagram conceptually illustrating how the touch screen 12 receives an instruction input when the second determination movement distance change process is executed.

The main control unit 30, the moving operation based on the instruction input of the finger F that is initiated from a point A ₂ by the user (instruction input scroll operation for first time) applied a default value smaller 24dot as determined travel distance. For example, the minimum moving distance that can be detected by the touch screen 12 (24 dots in this case) is used as the determination moving distance used for inputting the instruction for the first scroll process. In addition, the instruction input of the two-time scrolling process that starts the point B _2, running the default value larger 120dot as determined travel distance. In addition, the instruction input of the three-time scrolling process that starts the point C _2, was applied 50dot the default value as determined travel distance.

  The portable terminal 1 decreases the determination movement distance applied to the first scroll processing instruction input by the second determination movement distance change process, and increases the determination movement distance applied to the second scroll processing instruction input. By doing so, it is possible to improve the operability for a user who wants to input an instruction input for one scroll process.

  The fact that the user has started a moving operation for inputting an instruction is considered to intend to execute the scroll process at least once. For this reason, the mobile terminal 1 recognizes the short movement operation immediately after the start of the movement operation as the first instruction input by making the unit movement operation for the first instruction input smaller than the default value. Further, the mobile terminal 1 sets the unit movement operation for the second instruction input to a value larger than the default value, so that the second scroll process is executed after the first scroll process is executed. A longer time can be taken (provided that the speed of the moving operation is almost constant). Thereby, even if the movement distance of the movement operation of the user becomes too large, the mobile terminal 1 can stop the movement operation before the execution instruction of the second scroll process is input, It is possible to easily perform the movement operation of the determination movement distance immediately after the operation starts.

  Next, the third determination moving distance changing process will be described.

  FIG. 8 is a flowchart for explaining the third determination moving distance changing process executed by the main control unit 30 of the mobile terminal 1 in the present embodiment. The third determination moving distance changing process is a process for improving the operability by considering the moving speed of the moving operation.

  In step S <b> 31, the mobile terminal 1 is detecting a movement operation with respect to the touch screen 12 by the user.

  In step S32, the main control unit 30 determines whether or not the moving speed of the moving operation is greater than a reference value. The main control unit 30 acquires position information of the moving operation detected on the touch screen 12 from the input control unit 32 every predetermined time. The main control unit 30 acquires the speed of the moving operation from the moving distance and time obtained from the position information. The movement speed used for the determination in step S32 can be acquired based on the speed when the previous determination movement distance is moved, the average value of the movement speed obtained from a predetermined number of position information detected in the past, or the like. . Note that the reference value of the movement speed used for the determination in step S32 can be set based on the speed when the immediately preceding determination movement distance is moved, the average value of the predetermined number of movement speeds in the past, or the like. Further, the reference value of the moving speed may have a predetermined width, and the case where it is larger than the reference value corresponds to the case where it is larger than the maximum value of this reference value.

  If the main control unit 30 determines that the speed of the moving operation is greater than the reference value (YES in step S32), in step S33, the main control unit 30 sets the determination moving distance used for detection of the next (immediately) input instruction to the second value. Change to a distance smaller than the default distance. Along with this, the movement operation for inputting an instruction to execute the scroll process once requires an operation of a small distance compared to the normal time when the default value is set.

  On the other hand, when the main control unit 30 determines that the speed of the moving operation is not greater than the reference value (NO in step S32), in step S34, the main control unit 30 determines that the moving speed of the moving operation is lower than the reference value. It is determined whether or not. When the speed reference value used for determination in step S34 is given a range, the case where the speed is smaller than the reference value corresponds to the case where the speed is smaller than the minimum value of the reference value.

  If the main control unit 30 determines that the speed of the moving operation is smaller than the reference value (YES in step S34), the main control unit 30 sets the determination moving distance used for detection of the next (immediately) input instruction to the third in step S35. Change to a distance greater than the default distance. Along with this, the movement operation for inputting an instruction to execute the scroll process once requires an operation of a larger distance than the normal time in which the default value is set.

  On the other hand, if the main control unit 30 determines that the speed of the moving operation is not smaller than the reference value (NO in step S34), that is, if the speed of the moving operation is within the reference value, in step S36, the determined moving distance Is the default value as the first distance.

  In step S <b> 37, based on whether or not a detection signal is transmitted from the input control unit 32, it is determined whether or not the detection of the finger movement operation on the touch screen 12 is finished. If the main control unit 30 determines that the detection of the moving operation is continued (NO in step S37), the main control unit 30 returns to the speed determination step S32 and repeats the subsequent processing.

  On the other hand, if the main control unit 30 determines that the detection of the movement operation has ended (YES in step S37), the main control unit 30 ends the process.

In the third determination movement distance changing process, when the movement speed of the movement operation performed immediately before is larger than the reference value V _max (the maximum value of the reference value), the determination is smaller than the default value for the scroll process instruction input. Request travel distance. Further, in the third determination movement distance changing process, when the movement speed of the movement operation is smaller than the reference value V _min (minimum value of the reference value), a determination movement distance larger than the default value is requested for the instruction input of the scroll process. To do.

That is, the determination moving distance f (n, V _n ) (V _n is the moving speed of the moving operation) is

  FIG. 9 is a diagram conceptually illustrating how the touch screen 12 receives an instruction input when the third determination movement distance changing process is executed.

When the main control unit 30 obtains the movement speed of the movement operation at the points A _{3 to} B ₃ corresponding to the already determined movement distance, the movement at a speed larger than the reference value is detected. For this reason, the judgment travel distance to be used in the detection of the pointing input based on movement of the start point for the next point B ₃ as the default value 50dot smaller 30Dot. Moreover, when the main control unit 30 acquired the speed of the movement operation at the points B _{3 to} C ₃ , the main control unit 30 detected the movement at the speed of the reference value. Therefore, changing the determination moving distance used for detection of the pointing input based on movement of the start point for the next point C ₃ to the default values 50Dot.

Moreover, when the main control unit 30 acquired the speed of the moving operation at the points C _{3 to} D ₃ , the main control unit 30 detected the movement at a speed smaller than the reference value. For this reason, the judgment travel distance to be used in the detection of the pointing input based on movement of the start point for the next point D ₃ as the default value 50dot greater 100Dot.

  The portable terminal 1 can improve operability by changing the determination movement distance according to the movement speed of the movement operation by the third determination movement distance change process.

  Specifically, when the moving speed of the moving operation by the user is high, the mobile terminal 1 considers that a large scroll operation amount is desired, and can detect one scroll process with a small distance moving operation. In addition, when the moving speed of the moving operation by the user is low, the mobile terminal 1 considers that a fine scroll operation amount is desired, and can detect one scroll process with a moving operation over a large distance.

  For this reason, when a user desires a large scroll operation amount, the user can input a scroll processing instruction with a small amount of operation. On the other hand, when the user desires a small scroll operation amount, the user can input the necessary number of instructions while confirming whether or not the instruction input for one scroll process has been performed.

  Next, the 4th determination movement distance change process performed with the portable terminal 1 is demonstrated.

  FIG. 10 is a flowchart illustrating a fourth determination movement distance change process executed by the main control unit 30 of the mobile terminal 1 in the present embodiment. The fourth determination moving distance changing process is a process for improving the operability by considering the continuity of the moving operation.

  In step S <b> 41, the mobile terminal 1 is detecting a moving operation with respect to the touch screen 12 by the user.

  In step S42, the main control unit 30 determines whether or not the detection of the finger movement operation on the touch screen 12 has been completed. When it is determined that the detection of the movement operation has not ended (NO in step S42), the main control unit 30 stands by until the detection ends.

  On the other hand, if the main control unit 30 determines that the detection of the moving operation has ended (YES in step S42), the main control unit 30 sets a timer for measuring a predetermined time in step S43. The time measured by the timer at this time is a time when it is possible to determine that the time from the end to the start is intended for continuous instruction input for the scroll process when the user starts again after completing the moving operation. is there.

  In step S <b> 44, the main control unit 30 determines whether or not the detection of the finger movement operation on the touch screen 12 has been started again. When it is determined that the detection is not started (NO in step S44), the main control unit 30 waits until the detection is started.

  On the other hand, when determining that the detection has started (YES in Step S44), the main control unit 30 determines whether or not the timer for the predetermined time set in the timer setting step S43 has expired in Step S45. When it is determined that the timer has expired (YES in step S45), that is, after the detection of the moving operation in the detection end determination step S42, the main control unit 30 is predetermined until the detection start of the moving operation in the detection start determination step S44. If it is determined that the time has elapsed, in step S46, the determination moving distance used for the detection of the instruction input after the start of the movement operation detection is set as a default value as the first distance.

  On the other hand, if the main control unit 30 determines that the timer has not expired (NO in step S45), in step S47, the main control unit 30 determines that the input is detected after the start of detection of the movement operation. The movement distance is changed to a distance smaller than the default value as the second distance. Along with this, the movement operation for inputting an instruction to execute the scroll process once requires an operation of a small distance compared to the normal time when the default value is set.

  The main control unit 30 is set to a value smaller than the determination movement distance applied to the previous movement operation when the determination movement distance applied to the previous continuous movement operation that has ended is not the default value. The

  In the fourth determination movement distance changing process, when the detection of the movement operation is started again within a predetermined time after the detection of the movement operation, the determination movement distance smaller than the default value is input to the scroll process instruction input. Request.

That is, the determination movement distance f (M, T _{M_s} , T _{M_e} ) (M is the number of continuous movement operations when T is a _single movement operation from the start to the end of detection of the movement operation, T _{M_s.} Is the time when the M-th moving operation is started, and _{TM_e} is the time when the M-th moving operation is finished), where T is the time measured by the timer.

  FIG. 11 is a diagram conceptually illustrating how the touch screen 12 receives an instruction input when the fourth determination movement distance changing process is executed.

As shown in FIG. 11A, the main control unit 30 finishes detecting the continuous movement operation. Then, before the expiration of the timer set time T, detection of the moving operation is started to start the point A ₄ shown in FIG. 11 again (B). For this reason, the determination movement distance after the start of the movement operation is changed to a determination movement distance 30 dots which is smaller than the determination movement distance 50 dots used for detection in the previous continuous movement operation shown in FIG.

  This portable terminal 1 improves operability by reducing the determination movement distance according to the movement speed when the movement operation is continuously performed at short intervals by the fourth determination movement distance changing process. Can do.

  Specifically, when the user performs a continuous movement operation at short intervals, the mobile terminal 1 considers that a large scroll operation amount is desired, and can detect one scroll process with a small distance movement operation. I made it. For this reason, when a user desires a large scroll operation amount, the user can input a scroll processing instruction with a small amount of operation.

Further, the determination movement distance may be changed as described below based on the number M of consecutive movement operations (movement operations started before the timer expires) at short intervals.
[Equation 5]
f (M) = default value−β ₄ M

  Next, a fifth determination movement distance changing process will be described.

  FIG. 12 is a flowchart for explaining a fifth determination movement distance change process executed by the main control unit 30 of the mobile terminal 1 in the present embodiment. The fifth determination movement distance changing process is a process for improving the operability by taking into consideration the relative positions of continuously detected movement movements.

  In step S <b> 51, the portable terminal 1 determines whether or not the detection is started again after the detection of the movement operation on the touch screen 12 by the user is completed. In this step S51, the movement operation determined as “starting detection again after detection is completed” is, for example, at a short interval detected before a predetermined time has elapsed since the end of detection of the previous movement operation. It is a continuous movement operation.

  In step S <b> 52, the main control unit 30 determines whether or not the position where the movement operation has started is moving with respect to the position where the previous movement operation was completed. For example, when the movement operation is performed substantially parallel to the short side direction (or the long side direction) of the touch screen 12, is the start position of the movement operation moving in the long direction (or the short side direction) with respect to the end position? Determine whether or not. The longitudinal direction (or the short side direction) is assumed to extend in the first direction and the second direction opposite to the first direction.

  When the main control unit 30 determines that the start position of the moving operation has not moved with respect to the end position of the previous moving operation (NO in step S52), the instruction based on the restarted moving operation in step S53. The determination moving distance used for input detection is set as a default value as the first distance.

  On the other hand, when the main control unit 30 determines that the start position of the movement operation has moved with respect to the end position of the previous movement operation (YES in step S52), the start position of the movement operation is determined in step S54. Then, it is determined whether or not the movement has occurred in the first direction. If the main control unit 30 determines that the movement has occurred in the first direction (YES in step S54), in step S55, the determination is used to detect the instruction input until the resumed moving operation is completed. The moving distance is changed to a distance larger than the default value as the second distance. Along with this, the movement operation for inputting an instruction to execute the scroll process once requires an operation of a larger distance than the normal time in which the default value is set.

  On the other hand, when the main control unit 30 determines that the start position of the moving operation is a movement in the second direction instead of the first direction (NO in step S54), the main control unit 30 is resumed in step S56. Until the moving operation ends, the determination moving distance used for detecting the instruction input is changed to a distance smaller than the default value as the third distance. Along with this, the movement operation for inputting an instruction to execute the scroll process once requires an operation of a small distance compared to the normal time when the default value is set.

  In step S57, the main control unit 30 determines whether or not the detection of the continuous movement operation started in the start determination step S51 is finished. If the main control unit 30 determines that the detection of the movement operation has not been completed and has been continued (NO in step S57), the main control unit 30 waits until the detection of the movement operation is completed.

  On the other hand, if the main control unit 30 determines that the detection of the movement operation has ended (YES in step S57), the fifth determination distance movement operation change process ends.

  The fifth determination movement distance changing process is requested when the start position of the resumed movement operation is moved in a predetermined direction by the user's intentional movement with respect to the end position of the previous movement operation. The determination moving distance is changed.

That is, the determination movement distance f (M, Y _{M_s} , Y _{M_e} ) (Y _{M_s} is the start position coordinate on the predetermined axis of the M-th movement operation, and Y _{M_e} is the end position coordinate on the predetermined axis of the M-th movement operation) Is

_{Incidentally, (Y M_s -Y M-1_e} ) <0 in the case _{of, (Y M_s -Y M-1_e} ) <0 determined moving distance f in the case of it may be reversed. The changed determination moving distance f (M−1) may be used as a default value for the next change process.

  FIG. 13 is a diagram conceptually illustrating how the touch screen 12 receives an instruction input when the fifth determination movement distance change process is executed. FIG. 14 is a diagram conceptually illustrating another state in which the touch screen 12 receives an instruction input when the fifth determination movement distance changing process is executed.

  13 and 14, the moving operation is performed substantially parallel to the short side direction (X direction in the drawing) of the touch screen 12, and the moving operation start position is the first in the longitudinal direction with respect to the end position. It is determined whether or not there is a movement in the direction (Y direction in the figure) or the second direction (the direction opposite to the Y direction in the figure) that is opposite to the first direction. That is, the longitudinal direction (the Y direction in the drawing) is applied to the axis for determining whether or not the start position moves relative to the end position.

The determination moving distance applied to the first moving operation shown in FIGS. 13 and 14 is assumed to be a default value of 50 dots. Further, an example in which the changed determination movement distance (f (M−1)) is used as a default value for the next change process will be described with reference to FIGS. 13 and 14. The movement operation, movement operation starting from the point C _5, moving operation starting from the point E _5, and mobile operation for starting the point A ₆ of Fig. 14, starting at point A ₅ in FIG. 13, point movement of the C ₆ and starting point, the moving operation performed in succession at short intervals.

As illustrated in FIG. 13, the main control unit 30 determines the position coordinates of the end position B ₅ (first end position coordinates Y 1 — _e ) in the movement operation of the points A _{5 to} B ₅ that have already been performed. Then, using the position coordinates of the start position C ₅ in the movement operation started at the point C ₅ (second start position coordinates Y _{2 — s} ), it is determined whether or not movement in the Y-axis direction has occurred. Since the main control unit 30 determines that (Y ₂ — s −Y ₁ — _e <0) shown in [ _Expression 6] described above, the determination moving distance used in the moving operation started at the point C ₅ is determined from the default value of 50 dots. A small value of 40 dots (default value (f (1)) − α ₅ ) was used.

Thereafter, the main control unit 30, the position coordinates of the end position _{D 5} (second-time end position coordinates _{Y 2_e)} in movement of the point _C 5 to D ₅ corresponding to the determined movement distance has already been performed, the point _{E 5} in using the position coordinates of the starting position E ₅ in initiated movement (third-time start position coordinate _{Y 3_s),} was determined whether the movement of the Y-axis direction is generated. Since the main control unit 30 determines that (Y ₃ — s −Y ₂ — _e <0) shown in [ _Expression 6] described above, the determination moving distance used in the moving operation started at the point E ₅ is determined from the point C ₅ to the point C ₅ . was determined moving distance used in D ₅ 40dot smaller _{30dot (f (2) -α 5} ).

Further, as shown in FIG. 14, the main control unit 30 has already made the determination position coordinates (first-time end position coordinates Y of the movement end position B ₆ in movement of the point A ₆ .about.B ₆ which corresponds to the distance _{1_e} ) and the position coordinates (second start position coordinates Y _{2 — s} ) of the start position C ₆ in the movement operation started at the point C ₆ , it is determined whether or not movement in the Y-axis direction has occurred. It was. Since the main control unit 30 determines that (Y ₂ — s −Y ₁ — _e > 0) shown in [ _Expression 6] described above, the determination moving distance used in the moving operation started at the point C ₆ is determined from the default value of 50 dots. It was set to 70 dots (default value (f (1)) + β ₅ ).

  Note that the examples of FIGS. 13 and 14 are merely examples, and a movement operation may be performed in the longitudinal direction to determine whether or not there is movement in the short side direction.

  The portable terminal 1 changes operability by changing the determination movement distance according to the relative position between the end position of the movement operation and the start position of the movement operation started at a short interval thereafter by the fifth determination movement distance change process. Can be improved.

  Specifically, in the case where the start position of the movement operation started almost continuously in a short time with respect to the end position of the movement operation is the one that has moved in the first direction, The determination moving distance is reduced by assuming that the user desires more scroll processing intentionally. In addition, when the mobile terminal 1 is moved in the second direction that is opposite to the first direction, the mobile terminal 1 considers that the user desires a fine scroll operation amount intentionally. In addition, it is now possible to detect a single scroll process with a large distance movement.

  For this reason, when a user desires a large scroll operation amount, the user can input a scroll processing instruction with a small amount of operation. In particular, when moving in the short side direction, the moving operation distance is limited due to dimensional constraints, but by increasing the determination movement distance, a large amount of scroll processing can be executed with less operation. It is valid.

  On the other hand, when the user desires a small scroll operation amount, the user can input the necessary number of instructions while confirming whether or not the instruction input for one scroll process has been performed.

  The mobile terminal 1 configured to execute the above first to fifth determination movement distance changing processes suitably changes the determination movement distance as an input unit of the movement operation, so that the movement operation of the contact object is performed. The operability of the instruction input based on this can be improved.

  The first to fifth determination movement distance changing processes can be executed individually or in combination as appropriate.

  Moreover, although the portable terminal 1 in this embodiment applied and demonstrated the structure provided with the touch screen 12 with which the display and the input device were united, such as a touchpad with which the display and the input device were comprised separately, etc. It may be a pointing device.

  The portable terminal according to the present invention can also be applied to a cellular phone, a PDA (Personal Digital Assistant), a personal computer, a portable game machine, a portable music player, a portable video player, and other portable terminals.
