Description

Mobile device

The present invention relates to a portable terminal equipped with a pointing device such as a touch pad or a touch panel.

A mobile terminal such as a mobile phone is equipped with various input devices for receiving operation instructions from a user. Among these input devices, one that can input an operation instruction by an intuitive operation such as a touch pad or a touch panel is known (for example, see Japanese Patent Application Laid-Open No. 2008-258805). This touch pad or touch panel accepts an operation instruction based on input position information obtained by a touch sensor that senses a change in capacitance or contact pressure associated with contact with the operation surface.

When performing an operation for inputting an operation instruction to a touch panel or a touch pad, a stylus pen or a finger is generally used.

The stylus pen has a very small contact area with the operation surface, and the contact point with the operation surface is unlikely to change depending on how the user holds the stylus pen. For this reason, it is possible to cause the touch sensor to detect an input operation that matches the operation instruction intended by the user.

On the other hand, unlike the stylus pen, the finger has a large contact area with the operation surface. For this reason, there is a possibility that the touch sensor may detect the input position information by being dispersed within the contact range of the finger due to the influence of delicate force of the finger.

The mobile terminal executes various processes such as a display process based on the input position information detected by the touch sensor. However, as described above, when the input position information detected by the touch sensor changes due to the influence of a delicate finger force, there is a possibility of executing processing different from the operation instruction intended by the user. is there. For this reason, the user cannot obtain sufficient operability when performing an input operation using a finger.

Embodiments of a portable terminal according to the present invention will be described with reference to the accompanying drawings. As a portable terminal to which the present invention is applied, a portable terminal that is formed in a card shape and that allows a user to input an operation instruction by touching the display with a finger will be described as an example.

FIG. 1 is an external perspective view showing an embodiment of a portable terminal according to the present invention.

The mobile terminal 1 includes a rectangular plate-shaped casing 11. A touch panel 14 occupies most of one surface of the casing 11.

The touch panel 14 has both functions of a display unit and a detection unit.

The touch panel 14 as a display unit is a display (display 35 in FIG. 2) provided with an area for displaying a display screen composed of characters, images, and the like. This display includes, for example, an LCD (Liquid Crystal Display), an organic EL (ElectroLuminescence) display, and an inorganic EL display.

The touch panel 14 as a detection unit is a touch sensor (touch sensor 33 in FIG. 2) that detects a contact operation on the operation surface as input position information. The touch sensor includes a plurality of elements for detecting a contact operation arranged on the upper surface of the display, and a transparent operation surface laminated thereon. As a method for detecting the contact operation on the touch panel 14, a pressure-sensitive method for detecting a change in pressure, an electrostatic method for detecting an electric signal due to static electricity, or other methods can be applied.

The input position information is coordinate information indicating the position where the contact operation is performed. The input position information is represented by coordinate values on two axes, for example, with the short side direction of the touch panel 14 as the X axis and the long direction as the Y axis direction.

Further, a receiver 15 for outputting sound and a microphone 16 for inputting sound are disposed on the housing 11 at positions opposed to each other in the longitudinal direction via the touch panel 14.

FIG. 2 is a schematic functional block diagram showing the main functional configuration of the mobile terminal 1 in the present embodiment. The mobile terminal 1 is configured by connecting a main control unit 30, a power supply circuit unit 31, an input control unit 32, a display control unit 34, a voice control unit 36, a communication control unit 37, and a storage unit 39 so that they can communicate with each other via a bus. Has been.

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.

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 touch sensor 33. The input control unit 32 receives the detection signal from the touch sensor 33 as input position information indicating the coordinates of the input position every predetermined time (for example, every 7 ms), generates a signal indicating the input, and transmits the signal to the main control unit 30. To do.

The display control unit 34 includes a display interface for the display 35. The display control unit 34 causes the display 35 to display an image based on the document data and the image signal based on the control of the main control unit 30.

The sound control unit 36 generates an analog sound signal from the sound collected by the microphone 16 based on the control of the main control unit 30, and converts the analog sound signal into a digital sound 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 15.

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 based on the control of the main control unit 30. This data is transmitted to the voice control unit 36 and output from the receiver 15 according to an instruction from the main control unit 30, transmitted to the display control unit 34 and displayed on the display 35, or recorded in the storage unit 39. To do. When the communication control unit 37 acquires the voice data collected by the microphone 16, the data input via the touch panel 14, or the data stored in the storage unit 39 based on the control of the main control unit 30, Is spread over the data and 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 mobile terminal 1 in the present embodiment includes the touch panel 14 as described above. The touch panel 14 receives an instruction for an image or the like displayed on the display 35 of the touch panel 14 via the operation surface. The touch panel 14 performs an input operation on the touch panel via a user's finger or a stylus pen. For example, the user can hold the casing 11 with one hand and perform an input operation on the touch panel 14 using the finger of the other hand or the finger of the hand holding the casing 11. The

FIG. 3 is a diagram illustrating an example in which an operation instruction is performed on the cursor displayed on the touch panel 14.

On the touch panel 14, a cursor 41, which is an image used for pointing an operation target, is displayed. In addition, at a predetermined position on the touch panel 14, an area assigned as an operation pad 14a that exclusively receives an operation instruction for the cursor 41 is displayed. The input control unit 32 detects the input position information every predetermined time (for example, 7 ms) based on the input operation of the user who moves the finger F in contact therewith. The main control unit 30 performs display processing for moving the cursor 41 based on the detected input position information.

For example, when the mobile terminal 1 detects the movement of the finger F moving in the direction of the illustrated arrow A on the operation pad 14a, the cursor 41 moves correspondingly in the direction of the illustrated arrow B.

Here, when an input is performed on the touch panel 14 (operation pad 14a) using a finger, there is a problem with operability because the contact area of the finger with respect to the operation pad 14a is large.

FIG. 4 is a diagram conceptually showing the input position information detected by the touch sensor with respect to the input operation. FIG. 4A shows input position information detected when an input operation is performed using a stylus pen. FIG. 4B shows input position information detected when an input operation is performed using a finger. FIG. 4 shows the detection points of the input position information by the touch sensor as x marks when contact with the touch panel is continued at substantially the same position for a certain time.

The stylus pen has a very small contact area with the operation surface, and the contact point with the operation surface is unlikely to change depending on how the user holds the stylus pen. For example, as shown in FIG. 4A, the touch sensor can detect input position information from a single contact point. For this reason, it is possible to cause the touch sensor to detect an operation instruction that matches the operation instruction intended by the user.

On the other hand, when an input operation is performed using a finger, the fingertip or the belly of the finger is generally used. Unlike the stylus pen, the finger has a large contact area with the operation surface. For this reason, there is a possibility that the touch sensor may detect the input position information by being scattered within the contact range of the finger due to the influence of delicate force. For example, as shown in FIG. 4B, the touch sensor detects a large number of contact points in accordance with the finger force, so that the input position information is different from the original operation instruction expected by the user. Will be detected. Along with this, there is a possibility that the mobile terminal executes processing different from the operation instruction intended by the user.

FIG. 5 is a diagram illustrating an example of a cursor display process based on an operation instruction received through an input operation with a finger.

When the finger F is moved on the operation pad 14a in the direction of the illustrated arrow C and an operation instruction is input, a display process is performed in which the cursor 41 moves in the direction of the illustrated arrow D correspondingly. However, as described above, a large amount of input position information is detected within the contact range due to the delicate force applied by the finger. For this reason, as shown in FIG. 5, according to the input position information detected in a scattered manner, the cursor 41 also moves while being displayed in a scattered state.

In addition, when the user finishes inputting the operation instruction, the user performs an operation (release operation) of releasing the finger F from the operation pad 14a. In this release operation, even if the user simply intends to release the finger F, any part of the finger F having a large contact area may touch the operation pad 14a with delicate force. For this reason, when a release operation is performed on the operation pad 14a, input position information based on an unintended operation is detected, and display processing of the cursor 41 unintended for the user is performed.

The mobile terminal 1 according to the present embodiment realizes display processing with high accuracy by suitably invalidating an operation instruction not intended by the user even if the operation instruction is received via a finger having a large contact area. In addition, the visibility and operability of the touch panel can be improved. The operation instruction invalidation process with movement and the operation instruction invalidation process with release will be specifically described below.

FIG. 6 is a flowchart for explaining invalidation processing of an operation instruction accompanied by movement executed by the main control unit 30 of the mobile terminal 1 in the present embodiment.

In step S1, the main control unit 30 detects an instruction for moving the cursor from the operation pad 14a as the operation unit displayed on the touch panel 14. The main control unit 30 acquires the distance between the two contact points detected in succession from the input position information that is information about the contact points on the operation pad 14a.

The touch panel 14 acquires the input position information every predetermined time (for example, every 7 ms). For this reason, the main control unit 30 as a speed calculation unit can determine whether the movement between the contact points is fast or slow by obtaining the distance between the contact points. That is, when the distance between the contact points is large, the movement between the contact points is fast, and when the distance between the contact points is small, the movement between the contact points is slow.

In step S2, the main control unit 30 determines whether or not the acquired distance between the two contact points is equal to or less than a threshold value. The threshold value used for the determination at this time is a predetermined value determined in advance. This threshold value is set to a value that allows the movement between the contact points to be regarded as a fast action that has been unintentionally detected due to the delicate adjustment of the user's finger.

If the main control unit 30 determines that the distance between the contact points is greater than the threshold value (NO in step S2), at least one acquired before the contact point determined that the distance is greater than the threshold value in step S3. It is determined whether the distance between the contact points is equal to or less than a threshold value. In other words, the main control unit 30 determines whether or not the fast operation determined that the distance is larger than the threshold value is performed after the slow operation. This is because only a fast action after a slow action can be regarded as a sudden fast action that is not intended by the user.

At this time, the number of operations performed before the fast operation considered in the determination in the operation determination step S3 is not particularly limited. For example, only the speed of the previous action of the fast action may be considered, or the speed of the action two or more times before may be considered.

Note that this operation determination step S3 may be omitted in the operation invalidation process.

If the main control unit 30 determines that the operation is a fast operation after a slow operation (YES in step S3), in step S4, the main control unit 30 invalidates the movement between the two contact points targeted in the distance acquisition step S1. . That is, since the movement between the contact points is accompanied by an abrupt and quick operation, it is regarded as the input position information detected by the input operation not intended by the user. For this reason, this fast operation is invalidated and is not referred to when performing cursor display processing.

In step S5, the main control unit 30 performs a cursor display process on the touch panel 14 based on the input position information. When the distance between the contact points is equal to or less than the threshold value in the distance determination step S2 (YES in step S2), and in the operation determination step S3, if it is not a fast operation after the slow operation (NO in step S3), The main control unit 30 performs cursor display control corresponding to the detected input position information. That is, since the movement between the contact points is slow, or because the movement is not based on an abrupt fast movement, it can be regarded as the input position information detected with the input movement intended by the user. Therefore, the main control unit 30 performs cursor display control according to the detected input position information.

In contrast, in the distance determination step S2, the distance between the contact points is larger than the threshold (NO in step S2), and in the operation determination step S3, it is determined that the operation is a fast operation after the slow operation (YES in step S3). When the movement between the contact points is invalidated in the invalid step S4, the main control unit 30 performs display control of the cursor 41 corresponding to the input position information in which the movement between the contact points is invalidated.

This is the end of the description of the operation instruction invalidation process with movement in FIG.

Next, the display control process of the display step S5 in the operation instruction invalidation process accompanying the movement of FIG. 6 will be described. This display control process is executed every predetermined time (for example, every 14 ms). In other words, the cursor is moved and displayed every predetermined time.

FIG. 7 illustrates the movement distance referred to in the display control process executed every predetermined time in a predetermined two consecutive display control processes (shown as nth and (n + 1) th in FIG. 7). It is a table | surface which shows an example. FIG. 8 is a diagram showing a trajectory of the input operation obtained by the main control unit 30 from the input position information referred to in the n-th display control process. FIG. 9 is a diagram showing a movement locus of the cursor 41 based on the input operation of FIG. FIG. 10 is a diagram illustrating the locus of the input operation obtained by the main control unit 30 from the input position information referred to in the (n + 1) th display control process. FIG. 11 is a diagram showing a movement locus of the cursor 41 based on the input operation of FIG. That is, FIGS. 8 and 10 are diagrams illustrating the locus of the input operation obtained by the main control unit 30 from the input position information based on the input operation performed on the operation pad 14a. 9 and 11 show the locus of the cursor displayed on the display 35 of the touch panel 14.

In the display control process described below, a total of four pieces of input position information among three pieces of input position information acquired before the latest input position information from the latest input position information in order to perform one display control process. The distance is taken into account. The display control process of FIG. 7 is executed every 14 ms, for example, by acquiring input position information detected during the display control process. For example, when the input position information is detected every 7 ms, the main control unit 30 acquires an average value of the input position information for two times as newly detected input position information and uses it for the display control process. It has become.

FIG. 7 shows the moving distance obtained from the newly acquired input position information on the right side of each time. The movement distance on the left indicates the movement distance obtained in the previous display control process. 8 to 11, the distance “CurrentDist” is obtained from the input position information newly acquired in each display control process and the input position information detected in the previous display control process. The distance traveled is shown. The distance “Dist2” indicates the movement distance used to acquire the distance “CurrentDist” in the previous display control process. The distance “Dist1” indicates the movement distance used for acquiring the distance “CurrentDist” in the last display control process.

The main control unit 30 determines whether or not the movement distance obtained from the newly acquired input position information in each display control process is 5 or less set as a threshold (distance determination step S2 in FIG. 6). When the moving distance is equal to or less than the threshold value 5, the main control unit 30 regards the user's input operation as an operation with a low moving speed and is an effective operation, and performs cursor display processing according to the obtained input position information. I do. On the other hand, the main control unit 30 is invalid when the moving distance is larger than the threshold 5 and the user's input operation is an operation with a high moving speed and a movement based on a fast operation after a slow operation. It is regarded as an operation, and the display processing is performed with the movement of the cursor based on the input position information invalid.

In the n-th display control processing shown in FIGS. 7 and 8, the main control unit 30 has a slow input operation by the user because the movement distance Dist1 obtained at the (n−2) th time is 3 (Dist1 = 3). It was determined that there was. Further, the main control unit 30 determines that the user's input operation is a slow operation because the distance Dist2 obtained at the (n-1) th time is 4 (Dist2 = 4). Further, the main control unit 30 determines that the user's input operation is a fast operation because the latest (newly determined) travel distance CurrentDist is 6 (CurrentDist = 6) (NO in step S2). Further, the main control unit 30 determines that the latest movement distance CurrentDist is a fast operation after Dist2, which is a slow operation (YES in step S3).

Based on these determinations, the main control unit 30 invalidates the movement of the distance CurrentDist (step S4), and performs the cursor display processing while validating the movement of the distance Dist1 and the distance Dist2 (FIG. 9, step S5). A portion indicated by a dotted line in FIG. 9 indicates a locus of the invalid cursor.

The main control unit 30 acquires the movement distance CurrentDist obtained from the newly acquired input position information in the (n + 1) th display control process. In the (n + 1) th display control process shown in FIGS. 7 and 10, the main current control unit 30 determines that the user's input operation is a slow operation because the distance CurrentDist is 5 (YES in step S2).

At this time, the main control unit 30 obtains the input position information including the input position information whose movement is invalidated in the (n + 1) th display control process, that is, the CurrentDist = 6 invalidated in the nth display control process. Cursor display processing is performed with reference to the input position information of points A and B (see FIG. 10).

As shown in FIG. 10, the main control unit 30 performs a straight line obtained from the last trajectory of the cursor that has been effectively moved in the nth display control process (nth Dist2 trajectory) and the n + 1th display control process. An angle α formed with a straight line obtained from the locus of the cursor (n + 1th CurrentDist) treated as valid is acquired. As shown in FIG. 11, the main control unit 30 displays the last trajectory of the cursor displayed in the nth display control process (the nth Dist2 trajectory) and the cursor treated as valid in the n + 1th display control process. The cursor display process is performed so that the trajectory (n + 1th CurrentDist) forms this angle α. That is, the main control unit 30 performs cursor display control so that the starting point of the valid cursor locus after being invalidated coincides with the end point of the last valid cursor.

In the display control process described with reference to FIGS. 7 to 11, each time the display control process is performed using information acquired from the average value of the input position information detected every 7 ms as the input position information. However, for example, input position information detected from a contact point acquired every 7 ms may be used as it is in the display control process.

According to the portable terminal 1, by executing the invalidation process of the operation instruction accompanied by the movement, the above-described fast movement of the finger can be ignored, and the spread of the cursor 41 as shown in FIG. 5 is suppressed. be able to.

FIG. 12 is a diagram showing the input operation trajectory of the operation instruction using the thumb belly and the movement trajectory of the cursor based on the input operation. The touch panel 14 shown in FIG. 12 has shown the example using what was comprised, for example by the dimension of 88 mm long and 52 mm wide. Also, in FIG. 12, the display of the finger that has performed the input operation and the cursor is omitted.

When an operation instruction for moving the cursor using the thumb of the thumb is input in the direction of the arrow E on the operation pad 14a, the contact area of the thumb's belly is large. Will be detected in large numbers. However, by executing the invalidation process of the operation instruction accompanied by the movement in the present embodiment, it is preferable to ignore the fast operation among the input operations of the user, and to move the cursor in a substantially linear locus in the direction of the arrow F illustrated by the user. Can be drawn and moved.

Next, the operation instruction invalidation process with release will be described.

FIG. 13 is a flowchart for explaining operation instruction invalidation processing with release executed by the main control unit 30 of the mobile terminal 1 in the present embodiment.

In step S11, the main control unit 30 determines whether or not the detection of the input position information is finished. If the main control unit 30 determines that the detection of the input position information is still continued, the main control unit 30 waits until the end.

On the other hand, when it is determined that the detection of the input position information has ended, in step S12, the main control unit 30 serves as a direction calculation unit for a predetermined number (for example, three points) continuously detected immediately before the detection ends. A plurality of movement directions between the contact points are acquired from the input position information of the contact points. The number of contact points from which the moving direction is acquired may be three or more.

The main control unit 30 determines the moving direction of the contact point using, for example, the X-axis direction that matches the short-side direction of the touch panel 14 or the Y-axis direction that matches the long-side direction. Specifically, the main control unit 30 refers to the X-axis or Y-axis coordinate value of each point from the input position information based on a predetermined number of contact points detected continuously, and moves between the contact points. The direction with respect to the X axis or Y axis is obtained.

In addition, when acquiring the moving direction of the contact point, either the X axis or the Y axis is used.

In step S13, the main control unit 30 determines whether or not a plurality of movement directions between the predetermined number of contact points are the same. When the movement directions are the same, it is a case where the X coordinate value or the Y coordinate value moves uniformly in the direction of increasing or decreasing as the contact points move. If the movement directions do not match, the X coordinate value or Y coordinate value of each contact point does not move uniformly along with the movement of each contact point, and moves in both the increasing direction and the decreasing direction. It is a case.

If the main control unit 30 determines in step S13 that the plurality of movement directions between the predetermined number of contact points do not match (NO in step S13), in step S14, the movement direction is determined in movement direction acquisition step S12. The movement between the predetermined number of acquired contact points is invalidated. This is because the moving direction of the contact point has suddenly changed at the time of release, and can be regarded as a movement instruction based on an unintended operation accompanying the release operation.

Note that the movement between the contact points to be invalidated is not limited to this example, and only the movement between the two points detected last may be invalidated.

On the other hand, if the main control unit 30 determines in step S13 that a plurality of movement directions between the predetermined number of contact points match (YES in step S13), the main control unit 30 moves in the movement direction acquisition step S12 in step S15. Of the movements between the predetermined number of contact points whose directions are acquired, the movement between the two points detected last is invalidated. Even if the contact points move in the same direction, there is a high possibility that the user's unintended movement will be detected due to the influence of subtle finger force when the release movement is performed. is there.

In step S16, the main control unit 30 controls the display of the cursor based on the input position information in consideration of the movement invalidated in the invalid steps S14 and 15.

This completes the description of the invalid operation instruction processing accompanying the release of FIG.

Next, the display control process of the display step S16 in the invalidation process of the operation instruction accompanying the release in FIG. 13 will be described. It is a figure which shows the locus | trajectory of the input operation which the main control part 30 obtained from the input position information.

FIG. 14 is a diagram showing the locus of the input operation obtained by the main control unit 30 from the input position information based on the input operation when the moving directions between the three contact points are the same. FIG. 15 is a diagram showing a movement locus of the cursor based on the input operation of FIG. FIG. 16 is a diagram illustrating the locus of the input operation obtained by the main control unit 30 from the input position information based on the input operation when the moving directions between the three contact points do not match. FIG. 17 is a diagram showing a movement locus of the cursor based on the input operation of FIG. That is, FIGS. 14 and 16 are diagrams showing the locus of the input operation obtained by the main control unit 30 from the input position information based on the input operation performed on the operation pad 14a. 15 and 17 show the locus of the cursor displayed on the display 35 of the touch panel 14.

Note that the input position information used when acquiring the movement direction of the movement in FIGS. 14 to 17 is, for example, the average value of the input position information acquired every 7 ms twice, similarly to FIG. 7 described above.

In the description of the display control processing shown in FIGS. 14 to 17, the case where the number of pieces of input position information used for acquiring the moving direction is three points will be applied. Of the points shown in FIGS. 14 to 17, the point “Curr” is immediately before the release operation and indicates the input position information detected last. A point “Prev1” indicates input position information detected immediately before the point “Curr”. The point “Prev2” indicates the input position information detected immediately before the point “Curr”. In FIGS. 14 to 17, the value of the X coordinate of each input position information is used to determine the moving direction.

As shown in FIG. 14, the value of the X coordinate of the point Prev2 was 5 (x = 5). Further, the value of the X coordinate of the point Prev1 was 8 (x = 8). Further, the value of the X coordinate of the point Curr was 9 (x = 9). Since the X coordinate value of each point is moving in the increasing direction, the main control unit 30 determines that the moving directions between the contact points all coincide with the X axis direction (YES in step S13).

Therefore, the main control unit 30 invalidates the movement between the last detected point Prev1 and the point Curr among the contact points (step S15). The main control unit 30 moves the cursor on the touch panel 14 (display 35) as shown in FIG. 15 in consideration of the invalid movement (step S16). A portion indicated by a dotted line indicates a trajectory of the cursor that is invalidated.

On the other hand, as shown in FIG. 16, the value of the X coordinate of the point Prev2 was 6 (x = 6). Further, the value of the X coordinate of the point Prev1 was 7 (x = 7). Further, the value of the X coordinate of the point Curr was 5 (x = 5). Since the X coordinate value of each point moves in both the increasing direction and decreasing direction, the main control unit 30 determines that the moving direction between the contact points does not match the X axis direction (in step S13). NO).

For this reason, the main control unit 30 invalidates the movement between three points (point Prev2, point Prev1, point Curr) among the contact points (step S15). The main controller 30 moves the cursor on the touch panel 14 as shown in FIG. 17 in consideration of the invalid movement (step S16).

By executing the above-described processing, the mobile terminal 1 can invalidate the operation generated due to the influence of delicate finger force generated in the operation accompanied by the release, thereby further improving the operation instruction detection accuracy. be able to.

In addition, when the moving directions of the contact points all coincide on one axis, it is considered that the user's finger is separated from the operation pad 14a while facing (excessively) the input operation traveling direction. For this reason, the portable terminal 1 can perform the display processing of the cursor that is close to the user's operational feeling by invalidating the movement between the contact points detected last.

Furthermore, when the moving direction of the contact point does not coincide on one axis, it is considered that the user's finger is separated vertically from the operation pad 14a. That is, it is considered that a force directed in the direction opposite to the moving direction worked (excessively) on the finger. For this reason, the mobile terminal 1 invalidates the movement between the contact points detected before that in addition to the movement between the contact points detected last, in addition to the movement more than when the movement directions coincide. As a result, it is possible to perform a cursor display process close to the user's operational feeling.

Note that the input position information of the contact point used in the invalidation process of the operation instruction accompanying the release is not limited to three points, and input position information of three or more points may be used. In addition, if the movement directions of the contact points acquired immediately before the release operation are the same, the movement between the contact points detected immediately before the release operation is the same. If the movement directions are not the same, the movement directions are the same. Although an example of invalidating more movements than the above case has been described, movement between contact points to be invalidated is not limited to this example, and movement between more or less contact points may be invalidated.

According to the portable terminal 1, since the invalidation process of the operation instruction with movement and the operation instruction with release described above is executed, the movement operation of the cursor can be stabilized, and the display process for moving the cursor can be performed more accurately. It can be done at a higher level.

In the present embodiment, an example in which an operation instruction is input to the operation pad 14a with the finger F has been described. However, the present embodiment is applied to the case where the operation instruction is input through a touch area other than the finger F. Also good.

Moreover, although the portable terminal 1 in this embodiment applied and demonstrated the structure provided with the touchscreen 14 with which the display 35 and the touch sensor 33 were united, the touch sensor 33 is the touch comprised separately with the display 35. It may be a pointing device such as a pad.

Furthermore, the mobile terminal according to the present invention can be applied to a mobile 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.
