Abstract
The invention provides an electronic device, a slide operation processing method and a slide operation processing system, which can estimate the operation direction of the slide operation and judge whether the slide operation is finished within a preset time after the operation direction is changed aiming at the change of the operation direction. When the sliding operation is ended within a predetermined time after the change of the operation direction, the operation from the start of the change of the operation direction to the end of the sliding operation is invalidated. Thus, it is possible to easily determine whether the slide operation after the change of the operation direction is the valid operation desired by the user or the erroneous invalid operation, based on the operation duration after the change of the operation direction of the slide operation. This can prevent erroneous operation as much as possible and output a display screen or display information desired by the user.
Description
Technical Field
The present invention relates to an electronic device, a slide operation processing method, and a slide operation processing system, and more particularly, to an electronic device, a slide operation processing method, and a slide operation processing system that detect a slide operation by a user and distinguish between an effective operation and an erroneous operation.
Background
Touch panels such as touch panels are increasingly provided on various electronic devices such as mobile phones, tablet computers, personal computers, navigation devices, and user self-service terminals, so that users can perform intuitive operations by touching the touch panels. For example, the user may drag a certain distance with a finger on the touch panel, thereby performing a slide operation. By this sliding operation, the content displayed on the electronic apparatus can be scrolled on the screen or the display window in the direction corresponding to the direction of the sliding operation.
However, when the user performs a sliding operation by touch, the direction of the actual drag on the touch panel often does not completely coincide with the sliding direction desired by the user, resulting in that the displayed content cannot be scrolled in the direction desired by the user. For example, the size of the touch panel provided in various electronic devices varies, and in the case where the electronic device is a portable device such as a portable telephone, the size of the touch panel tends to be small, and it is difficult for a user to perform a delicate operation on the touch panel with a finger, which is likely to cause the above-described problem. In addition, in the case where the electronic apparatus is a portable device, if the electronic apparatus itself moves during the operation of the user, the above-described problem is likely to occur.
In view of this, patent document 1 proposes a portable communication terminal in which, when a user performs a slide operation on a touch panel, if it is determined that the direction of a position vector input from the touch panel is reversed with respect to the previous direction, the moving speed of the touch position or the direction change angle of the position vector is determined next, and the scroll direction of the display content is reversed only when the moving speed or the direction change angle is larger than a threshold value. Thus, if the touch position of the user moves slowly or the operation direction changes little, it is not considered that the user is an intentional slide operation, and the scroll direction of the displayed content is not reversed regardless of the direction of movement, thereby reducing erroneous operations by the user (paragraphs 0043, 0044, 0050, and 0054 in the description).
However, when the user performs a slide operation by touch, another erroneous operation may occur. As a case often occurs, when a user performs a slide operation on the touch panel and wants to end the operation, the finger is not immediately separated from the touch panel completely due to the operation accuracy of the user or the movement of the electronic device, and finally drags for some distance in a direction different from the direction of the slide operation desired by the user. In addition, not only in the touch operation, but also in the case where the user performs a slide operation by, for example, pressing down the left mouse button, the direction of the slide operation often changes unexpectedly due to vibration caused by releasing the left mouse button when the operation is ended. In this case, the conventional technique such as patent document 1 cannot distinguish this case from a case where the user intentionally changes the slide operation direction, and as a result, there is a technical problem that a display screen or display content desired by the user cannot be obtained.

Disclosure of Invention
In view of the above-described problems of the prior art, it is an object of the present invention to provide an electronic device, a slide operation processing method, and a slide operation processing system that can more accurately distinguish whether a slide operation by a user is a valid operation desired by the user or an erroneous invalid operation.
In order to achieve the above object, the present invention provides an electronic device including an operation unit capable of receiving a user operation and a detection unit for detecting the user operation, the electronic device further including: an operation direction estimating unit configured to estimate an operation direction of the slide operation with respect to the slide operation detected by the detecting unit; a determination unit configured to determine whether or not the sliding operation is completed within a predetermined time after the change in the operation direction, with respect to the change in the operation direction; and an operation acceptance control unit configured to invalidate an operation from a start of the change of the operation direction to an end of the sliding operation when the sliding operation is ended within the predetermined time after the change of the operation direction.
As described above, when the user performs a slide operation and intends to end the operation, the slide operation may be unexpectedly continued for some distance in a direction different from the operation direction desired by the user due to the operation accuracy of the user, the movement of the electronic apparatus, or the like. According to the electronic apparatus of the present embodiment, in this case, it is possible to easily determine whether the slide operation after the change in the operation direction is the valid operation desired by the user or the erroneous invalid operation, based on the operation duration after the change in the operation direction of the slide operation. This can prevent erroneous operation as much as possible and output a display screen or display information desired by the user.
In the electronic device according to the present invention, the determination unit may further include a change angle determination unit that determines whether or not a change angle of the operation direction is larger than a predetermined angle threshold, and when the sliding operation is completed within the predetermined time after the change of the operation direction, the operation acceptance control unit may invalidate the operation from the start of the change of the operation direction to the end of the sliding operation when the change angle of the operation direction is larger than the angle threshold, and may validate the operation from the start of the change of the operation direction to the end of the sliding operation when the change angle of the operation direction is equal to or smaller than the angle threshold.
Thus, when the operation direction of the slide operation is changed but is close to the original operation direction, the user determines that the operation is desired to be effective even if the operation duration after the change of the operation direction is short. This makes it possible to more accurately distinguish between an effective operation and an erroneous operation desired by the user.
In the electronic apparatus according to the present invention, the determination unit may further include: a first change occurrence determination unit that determines whether the operation direction has changed during the sliding operation; a timer unit that counts the predetermined time from when the operation direction starts to change every time the operation direction changes; and a first operation end determination unit configured to determine whether or not the sliding operation has ended within the predetermined time counted by the timer unit, and determine that the sliding operation has ended within the predetermined time after the operation direction has changed when the sliding operation has ended within the predetermined time.
Thus, when the slide operation is finished within a predetermined time after the operation direction of the slide operation is changed, it is immediately determined that the operation after the operation direction change is an erroneous invalid operation, and the display screen or the display information is output in accordance with the determination result, thereby improving the responsiveness of the apparatus.
In the electronic apparatus according to the present invention, the operation acceptance control unit may validate the operation after the change of the operation direction when the first operation termination determination unit determines that the sliding operation is not terminated within the predetermined time.
Thus, even when the slide operation is not completed after a predetermined time has elapsed since the operation direction of the slide operation was changed, it is immediately determined that the operation after the change of the operation direction is an effective operation desired by the user, and the display screen or the display information is output in accordance with the determination result, so that the normal operation of the user is not affected.
In the electronic device of the present invention, the determination unit may further include: a second operation end determination unit that determines whether or not the slide operation is ended; a second change occurrence determination unit that determines whether or not the operation direction has changed within the predetermined time period before the end of the sliding operation when the second operation end determination unit determines that the sliding operation has ended, and determines that the sliding operation has ended within the predetermined time period after the change in the operation direction when the operation direction has changed within the predetermined time period.
Thus, when the slide operation is completed, it is determined whether the operation direction has changed within a predetermined time before the completion, and thus it is possible to distinguish whether the operation before the slide operation is completed is a valid operation desired by the user or an erroneous invalid operation, and the number of determinations is reduced, thereby reducing the processing load of the electronic apparatus.
In the electronic device according to the present invention, the detection unit may detect information of an operation point at which a user touches the operation unit, the operation direction estimation unit may estimate the operation direction of the sliding operation based on information of a plurality of operation points continuously detected by the detection unit at a minimum detection cycle, and the determination unit may determine whether or not the sliding operation is completed within a predetermined subsequent time after the deviated operation point with respect to an operation point deviated from the previous operation direction, and the operation acceptance control unit may invalidate the deviated operation point and the subsequent operation point among the sliding operations when the sliding operation is completed within the subsequent time after the deviated operation point.
Thus, when the operation direction of the sliding operation of the touch panel by the user is changed and an operation point deviated from the previous direction appears, it is possible to easily determine whether the deviated point and the subsequent sliding operation are valid operations desired by the user or erroneous invalid operations based on the operation duration after the deviated operation point.
In the electronic apparatus according to the present invention, the determination unit may determine whether or not the operation point after the deviated operation point is less than a predetermined number, and when the operation point after the deviated operation point is less than the predetermined number, the determination unit may determine that the sliding operation is ended within a predetermined subsequent time after the deviated operation point.
Thus, by a simple process of determining the number of operation points subsequent to the deviated operation point, it is possible to determine whether the sliding operation at the deviated point and subsequent thereto is a valid operation desired by the user or an erroneous invalid operation, thereby reducing the processing load of the electronic apparatus.
In the electronic apparatus according to the present invention, the operation direction estimating unit may estimate the operation direction of the slide operation by correcting a direction in which adjacent operation points are connected, based on a distance between the plurality of operation points detected continuously by the detecting unit and an increase or decrease in coordinates between the plurality of operation points.
In this way, in the case where the operation direction of the user deviates from the desired direction to some extent, the direction actually desired by the user can be estimated as much as possible, and the display screen or the display information desired by the user can be output accordingly.
The invention also provides a sliding operation processing method for processing the sliding operation performed by the user, which is characterized by comprising the following steps: an operation direction estimation step of estimating an operation direction of the detected slide operation; a determination step of determining whether or not the slide operation is ended within a predetermined time after the change of the operation direction, with respect to the change of the operation direction; and an operation acceptance control step of invalidating an operation from the start of the change of the operation direction to the end of the sliding operation when the sliding operation is ended within the predetermined time after the change of the operation direction.
The present invention also provides a slide operation processing system for processing a slide operation performed by a user, comprising: an operation direction estimating unit configured to estimate an operation direction of the detected slide operation; a determination unit configured to determine whether or not the sliding operation is completed within a predetermined time after the change in the operation direction, with respect to the change in the operation direction; and an operation acceptance control unit configured to invalidate an operation from a start of the change of the operation direction to an end of the sliding operation when the sliding operation is ended within the predetermined time after the change of the operation direction.
The above various aspects of the electronic device of the present invention can also be applied to the sliding operation processing method and the sliding operation processing system of the present invention, and corresponding technical effects are obtained.

The present invention will be described in more detail below with reference to the accompanying drawings, embodiments, and specific examples. The following description is only an example for the convenience of understanding the present invention and is not intended to limit the scope of the present invention. In the embodiments, the components of the apparatus may be changed, deleted or added according to the actual situation, and the steps of the method may be changed, deleted, added or changed in order according to the actual situation.

(first embodiment)
The first embodiment of the present invention will be specifically explained. First, an electronic device 1 according to a first embodiment of the present invention will be described. The electronic device 1 is a portable or fixed device such as a mobile phone, a tablet computer, a personal computer, a navigation device, or a user self-service terminal. The electronic apparatus 1 may have a display unit itself, or may be connected to an external display device so as to display various display screens and display information such as a GUI (graphical user interface), text, images, and maps to the user. Fig. 1 is a block diagram of an electronic device 1 according to a first embodiment of the present invention, in which arrows indicate directions of operations or data transmission. As shown in fig. 1, the electronic device 1 includes an operation unit 11, a detection unit 12, an operation direction estimation unit 13, a determination unit 14, and an operation reception control unit 15. The following description will be specifically made.
The operation unit 11 is a touch panel that can receive an operation by a user, and for example, a touch operation by the user. Here, the touch panel may be a touch panel (touchable display panel) having a display function, or may be a touch area provided separately from the display panel. The operation of the touch panel by the user includes, for example, various touch operations such as a single click, a slide, and a drag, and various gesture operations by multi-touch. The operation unit 11 is not limited to a touch panel, and may be implemented by other operation devices such as a trackball and a mouse. The user can perform various operations such as clicking, sliding, and dragging by operating these operation devices.
The detection unit 12 detects a user operation received by the operation unit 11, and in the case where the operation unit 11 is a touch panel, the detection unit 12 is implemented by, for example, a touch sensor, detects a contact operation of the user with respect to the operation unit 11, and outputs information related to the user operation such as contact position information. The touch sensor is configured by a plurality of contact detection elements disposed between the display panel and the touch panel, and may be a pressure-sensitive sensor that senses a pressure change, an electrostatic sensor that senses an electrostatic signal, or another touch sensor. In addition, when the operation unit 11 is another operation device such as a trackball or a mouse, it is possible to detect a user operation received by the operation unit 11 and output related operation information by various conventional methods.
The operation direction estimating unit 13 estimates the operation direction of the slide operation detected by the detecting unit 12. The slide operation is an operation in which the user drags a certain distance in an input state to the operation unit 11 (for example, a contact state to the touch panel, a pressed state of the left mouse button, or the like). The operation direction estimating unit 13 can estimate the operation direction of the sliding operation based on, for example, the trajectory (trend) of the sliding operation detected by the detecting unit 12. The operation direction estimating unit 13 may be realized, for example, by a processor (control unit) of the electronic apparatus 1 executing an operation direction estimating program stored in a memory (storage unit), or may be realized by dedicated hardware included in the electronic apparatus 1. Generally, the display screen or the display information output by the electronic apparatus 1 is scrolled in a direction corresponding to the operation direction of the slide operation based on the slide operation.
The determination unit 14 determines whether or not the sliding operation is completed within a predetermined time after the change in the operation direction of the sliding operation. The operation direction of the sliding operation changes, for example, the direction of the sliding trajectory (trend) changes (or changes to a certain extent or more) during the sliding operation. The end of the slide operation means that the detection unit 12 can no longer detect the slide operation by the user and no longer outputs information on the slide operation. When the operation unit 11 is a touch panel, the finger of the user being away from the operation unit 11 means that the slide operation is completed. The determination unit 14 may be realized by a processor (control unit) of the electronic device 1 executing a determination program stored in a memory (storage unit), or may be realized by dedicated hardware provided in the electronic device 1.
The predetermined time is, for example, 30ms, and may be set as appropriate according to the size of the operation unit 11, the detection frequency of the detection unit 12, the application and processing speed of the electronic device 1, the operation habit of the user, and the like. For example, when the operation unit 11 is small in size or the electronic device 1 is a portable device, and the user is likely to perform an erroneous operation, the predetermined time may be extended as long as possible so that the erroneous operation by the user can be recognized as much as possible. In addition, when the detection frequency of the detection unit 12 is low, the predetermined time may be appropriately extended so that more reliable determination can be made based on more operation information after the operation direction is changed.
When the sliding operation is completed within a predetermined time after the operation direction of the sliding operation is changed, the operation reception control unit 15 invalidates the operation from the start of the change of the operation direction to the end of the sliding operation. In other words, in the above case, the operation reception control unit 15 controls the operation to end when the change in the operation direction starts for the slide operation by the user. Thus, the display screen or the display information output from the electronic apparatus 1 does not scroll in the slide operation direction after the change in the operation direction. The operation reception control unit 15 may be realized by a processor (control unit) of the electronic device 1 executing an operation reception control program stored in a memory (storage unit), or may be realized by dedicated hardware provided in the electronic device 1.
As described above, when the user performs a slide operation and intends to end the operation, the slide operation may be unexpectedly continued for some distance in a direction different from the operation direction desired by the user due to the operation accuracy of the user, the movement of the electronic apparatus, or the like. According to the electronic apparatus 1 of the present embodiment, in this case, it is possible to easily determine whether the slide operation after the change in the operation direction is the valid operation desired by the user or the erroneous invalid operation, based on the operation duration after the change in the operation direction of the slide operation. This can prevent erroneous operation as much as possible and output a display screen or display information desired by the user.
Next, a method of processing a slide operation performed by the electronic device 1 according to the first embodiment of the present invention will be described, and a specific example of the present embodiment will be described with reference to the method of processing a slide operation. Fig. 2 is a flowchart of a sliding operation processing method according to the first embodiment of the present invention. The flow of the sliding operation processing method shown in fig. 2 is executed, for example, each time the electronic apparatus 1 receives a sliding operation by the user. Fig. 3 is a schematic diagram of a specific example of the sliding operation according to the first embodiment of the present invention. An operation trajectory 302 in which the user performs a slide operation with respect to the operation region 301 of the operation section 11 is shown. As shown in fig. 3, when the user starts the slide operation from the position S and slides rightward in the substantially horizontal direction to the position R, the user wants to end the slide operation, but the user ends the slide operation after sliding from the position R to the position E in a direction (upper right direction) different from the previous slide direction due to an erroneous operation.
In contrast, as shown in fig. 2, first, in step S201 (operation direction estimating step), the operation direction estimating unit 13 estimates the operation direction of the detected slide operation. In the specific example shown in fig. 3, the operation direction estimating unit 13 estimates that the operation direction of the slide operation is substantially horizontal between the position S and the position R, and changes from the position R to the upper right direction.
Next, in step S202 (determination step), the determination unit 14 determines whether or not the sliding operation is finished within a predetermined time after the change of the operation direction with respect to the change of the operation direction. Here, the time elapsed from the position R to the position E is less than a predetermined time (for example, 30 ms). Therefore, it is determined that the sliding operation is ended within a predetermined time after the operation direction is changed, and step S203 is executed next. In addition, if the judgment result is no, step S204 is executed next.
In step S203 (operation acceptance control step), the operation acceptance control section 15 invalidates the operation from the start of the change in the operation direction until the end of the sliding operation, that is, the operation from the position R to the position E, and ends the flow.
In step S204, the operation reception control unit 15 validates the operation after the start of the change in the operation direction, and returns to step S201.
Here, an example of a display screen corresponding to the specific example shown in fig. 3 is shown in which the electronic apparatus 1 is a navigation apparatus and a map is displayed on the display screen. Fig. 4A is a schematic view of a display screen corresponding to a specific example of the slide operation according to the first embodiment of the present invention, and shows the display screen when the user starts the slide operation in fig. 3. As shown in fig. 4A, the substantially elliptical starsea square is located at the left end of the frame and is not fully displayed.
Fig. 4B is a schematic diagram of a display screen corresponding to a specific example of the slide operation according to the first embodiment of the present invention, and shows the display screen after the user has performed a desired slide operation in fig. 3. As shown in fig. 4B, based on the sliding operation in the substantially horizontal direction to the right (position S to position R) shown in fig. 3, the substantially elliptical starfish square is positioned at the center of the screen, is completely displayed, and is suitable for the user to view.
Fig. 4C is a schematic view of a display screen corresponding to a specific example of the slide operation according to the first embodiment of the present invention, and shows the display screen after the user has performed an erroneous operation in fig. 3. As shown in fig. 4C, since the user has erroneously operated in the upper right direction (position R to position E) before the sliding operation is completed, the substantially elliptical starsea square is shifted to the upper right of the screen, is not completely displayed, and is again in a state not suitable for the user to observe.
According to the electronic apparatus 1 and the slide operation processing method executed by the same of the present embodiment, as described above, the operation from the position R to the position E can be invalidated, and the screen display shown in fig. 4B desired by the user can be maintained.
(second embodiment)
The second embodiment of the present invention will be specifically explained. The present embodiment is added to the first embodiment in the determination of the operation direction change angle for the slide operation. The following description focuses on differences of the present embodiment from the first embodiment, and the same or similar contents as or to the first embodiment will be omitted in the present embodiment.
In the present embodiment, the determination unit 14 further includes a change angle determination unit (not shown) that determines whether or not the change angle of the operation direction is larger than a predetermined angle threshold. When the sliding operation is ended within a predetermined time after the operation direction of the sliding operation is changed, the operation reception control unit 15 invalidates the operation from the start of the change of the operation direction to the end of the sliding operation only when the change angle of the operation direction is larger than the angle threshold. On the other hand, when the change angle of the operation direction is equal to or smaller than the angle threshold, the operation reception control unit 15 validates the operation from the start of the change of the operation direction to the end of the slide operation.
The predetermined angle threshold is set to 45 degrees or 90 degrees, for example, in advance, and the operation accuracy level of the slide operation received by the electronic apparatus 1 can be estimated based on the size of the operation unit 11, the application of the electronic apparatus 1, the operation habit of the user, and the like, and the angle threshold can be set as appropriate based on the operation accuracy level.
According to the electronic apparatus 1 of the present embodiment, when the operation direction of the slide operation is changed but is close to the original operation direction, it is determined that the user desires an effective operation even if the operation duration after the change of the operation direction is short. This makes it possible to more accurately distinguish between an effective operation and an erroneous operation desired by the user.
Next, a method of processing a slide operation performed by the electronic device 1 according to the second embodiment of the present invention will be described, and a specific example of the present embodiment will be described with reference to the method of processing a slide operation. Fig. 5 is a flowchart of an example of a slide operation processing method according to a second embodiment of the present invention. The flow of the slide operation processing method shown in fig. 5 is executed, for example, each time the electronic apparatus 1 receives a slide operation by the user. Fig. 6 is a schematic diagram of a specific example of the slide operation according to the second embodiment of the present invention, and shows an operation trajectory 302 in which the user performs the slide operation on the operation region 301 of the operation unit 11. As shown in fig. 6, the operation direction of the slide operation is changed at the position R by the angle a.
Step S501 is the same as step S201 in fig. 2 of the first embodiment, and is not described herein again.
Next, in step S502 (determination step), the determination unit 14 determines whether or not the sliding operation is finished within a predetermined time after the change of the operation direction with respect to the change of the operation direction. If the judgment result is yes, step S503 is executed next. In addition, if the determination result is no, step S505 is executed next.
In step S503 (change angle determination step), the change angle determination unit determines whether or not the change angle of the operation direction of the slide operation is larger than a predetermined angle threshold. In the case where the determination result is yes, that is, the variation angle a in fig. 6 is larger than the angle threshold value, step S504 is executed next. If the determination result is no, that is, if the change angle a in fig. 6 is equal to or smaller than the angle threshold value, step S505 is executed next.
In step S504 (operation reception control step), the operation reception control unit 15 invalidates the operation from the start of the change in the operation direction to the end of the sliding operation, that is, the operation from the position R to the position E, and ends the flow.
In step S505, the operation reception control unit 15 validates the operation after the start of the change in the operation direction, and returns to step S501.
Fig. 7 is a flowchart of another example of the slide operation processing method according to the second embodiment of the present invention. The flow of the slide operation processing method shown in fig. 7 is executed, for example, each time the electronic apparatus 1 receives a slide operation by the user.
Step S701 is the same as step S201 in fig. 2, and is not described herein again.
Next, in step S702 (change angle determination step), the change angle determination unit determines whether or not the change angle of the operation direction of the slide operation is larger than a predetermined angle threshold. If the determination result is yes, step S703 is executed next. In the case where the determination result is no, step S705 is executed next.
In step S703 (determination step), the determination unit 14 determines whether or not the sliding operation has ended within a predetermined time after the change in the operation direction, in response to the change in the operation direction. If the judgment result is yes, step S704 is executed next. In addition, if the determination result is no, step S705 is executed next.
Step S704 is the same as step S203 in fig. 2, and is not described herein. The flow is then ended.
In step S705, the operation reception control unit 15 validates the operation after the start of the change of the operation direction, and returns to step S701.
According to the two examples of the sliding operation processing method executed by the electronic device 1 of the second embodiment, the effective operation and the erroneous operation desired by the user can be more accurately distinguished.
(third embodiment)
The third embodiment of the present invention will be specifically explained. This embodiment describes a specific embodiment of the determination unit 14 in the electronic device 1 according to the first embodiment or the second embodiment. The contents already described in the first embodiment or the second embodiment are not described in the present embodiment.
In the present embodiment, the determination unit 14 further includes a first change occurrence determination unit, a timer unit, and a first operation end determination unit (all not shown). The first change occurrence determination section determines whether or not the operation direction of the slide operation has changed during the slide operation. The timer unit counts a predetermined time (for example, 30ms) from the time when the operation direction starts to change every time the operation direction changes. The first operation end determination unit determines whether or not the sliding operation is ended within a predetermined time counted by the timer unit, and if the sliding operation is ended, determines that the sliding operation is ended within a predetermined time after the operation direction is changed.
According to the electronic device 1 of the present embodiment, when the slide operation is finished within a predetermined time after the operation direction of the slide operation is changed, it is immediately determined that the operation after the operation direction change is an erroneous invalid operation, and the display screen or the display information is output in accordance with the determination result, thereby improving the responsiveness of the device.
Further, when the first operation end determination unit determines that the sliding operation has not ended within the predetermined time counted by the time counting unit, the operation reception control unit 15 validates the operation after the change of the operation direction.
Thus, even when the slide operation is not completed after a predetermined time has elapsed since the operation direction of the slide operation was changed, it is immediately determined that the operation after the change of the operation direction is an effective operation desired by the user, and the display screen or the display information is output in accordance with the determination result, so that the normal operation of the user is not affected.
Next, a method of processing a slide operation performed by the electronic apparatus 1 according to the third embodiment of the present invention will be described. Fig. 8 is a flowchart of a sliding operation processing method according to a third embodiment of the present invention. The flow of the slide operation processing method shown in fig. 8 is executed, for example, each time the electronic apparatus 1 receives a slide operation by the user. Steps S801, S805, and S806 are the same as steps S201, S203, and S204 in fig. 2 of the first embodiment, respectively. Steps S802 to S804 correspond to a specific embodiment of step S202 (determination step) in fig. 2 of the first embodiment.
In step S802 (first change occurrence determination step), the first change occurrence determination section determines whether the operation direction of the sliding operation has changed during the sliding operation. In the case where the determination result is yes, step S803 is executed next. In the case where the determination result is no, step S806 is executed next.
In step S803 (timing step), the timing unit counts a predetermined time, for example, 30ms, from when the operation direction starts to change.
Next, in step S804 (first operation end determination step), the first operation end determination unit determines whether or not the slide operation has ended within a predetermined time (for example, 30ms) of the time measurement. If the determination result is yes, step S805 is executed next. In the case where the determination result is no, step S806 is executed next.
In step S805 (operation reception control step), the operation reception control unit 15 invalidates the operation from the start of the change in the operation direction to the end of the sliding operation, and ends the flow.
In step S806, the operation reception control unit 15 validates the operation after the start of the change in the operation direction, and returns to step S801.
The sliding operation processing method according to the present embodiment is described above as an example of a specific implementation of the sliding operation processing method according to the first embodiment. Further, by replacing step S502 in fig. 5 or step S703 in fig. 7 with step S802 to step S804 described above, the slide operation processing method of the present embodiment can also be implemented as one specific embodiment of the slide operation processing method of the second embodiment.
(fourth embodiment)
The fourth embodiment of the present invention will be specifically explained. This embodiment describes another specific embodiment of the determination unit 14 in the electronic device 1 according to the first embodiment or the second embodiment. The contents already described in the first embodiment or the second embodiment are not described in the present embodiment.
In the present embodiment, the determination unit 14 further includes a second operation completion determination unit and a second change occurrence determination unit. The second operation end determination section determines whether or not the slide operation is ended. When the second operation end determination unit determines that the sliding operation has ended, the second change occurrence determination unit determines whether or not the operation direction has changed within a predetermined time (for example, 30ms) before the sliding operation has ended. When the change has occurred, it is determined that the sliding operation has ended within a predetermined time after the change in the operation direction.
According to the electronic apparatus 1 of the present embodiment, when the slide operation is ended, it is determined whether the operation direction has changed within the predetermined time before the end, and thus it is possible to distinguish whether the operation before the end of the slide operation is a valid operation desired by the user or an erroneous invalid operation, and the number of determinations is reduced, thereby reducing the processing load of the electronic apparatus 1.
Next, a method of processing a slide operation performed by the electronic apparatus 1 according to the fourth embodiment of the present invention will be described. Fig. 9 is a flowchart of a sliding operation processing method according to a fourth embodiment of the present invention. The flow of the slide operation processing method shown in fig. 9 is executed, for example, each time the electronic apparatus 1 receives a slide operation by the user. Steps S901 and S904 are the same as steps S201 and S203 in fig. 2 of the first embodiment, respectively. Steps S902 to S903 correspond to another specific embodiment of step S202 (determination step) in fig. 2 of the first embodiment.
In step S902 (second operation end determination step), the second operation end determination section determines whether or not the slide operation has ended. If the determination result is yes, step S903 is executed next. In the case where the determination result is no, step S905 is executed next. In step S905, the operation reception control unit 15 validates the sliding operation being performed, and returns to the step S901 to be executed next.
In step S903 (second change occurrence determination step), the second change occurrence determination unit determines whether or not the operation direction of the slide operation has changed within a predetermined time before the end of the operation, the predetermined time being, for example, 30 ms. In a case where the determination result is yes, step S904 is executed next. In the case where the determination result is no, step S906 is executed next.
In step S904 (operation reception control step), the operation reception control unit 15 invalidates the operation from the start of the change in the operation direction to the end of the sliding operation, and ends the flow.
In step S906, the operation reception control unit 15 validates the slide operation before the end, and ends the flow.
The slide operation processing method according to the present embodiment is described above as an example of a specific implementation of the slide operation processing method according to the first embodiment. Further, by replacing step S502 in fig. 5 with the above-described steps S902 to S903, the slide operation processing method of the present embodiment can also be realized as one specific embodiment of the slide operation processing method of the second embodiment.
(fifth embodiment)
The fifth embodiment of the present invention will be specifically explained. This embodiment describes a specific embodiment of the electronic device 1 according to any one of the first to fourth embodiments. The contents already described in the first to fourth embodiments are omitted in this embodiment.
The present embodiment is applied to a case where the operation unit 11 of the electronic apparatus 1 is a touch panel and receives a touch operation by a user. In the present embodiment, the detection unit 12 detects information of an operation point at which the user performs a touch operation on the operation unit 11. The operation direction estimating unit 13 estimates the operation direction of the sliding operation based on information of a plurality of operation points continuously detected by the detecting unit 12 at a minimum detection cycle (for example, 10 ms). The determination unit 14 determines whether or not the sliding operation is finished within a predetermined time period after the operation point deviated from the previous operation direction. When the sliding operation is completed, the operation reception control unit 15 invalidates the operation point deviated from the sliding operation and the operation points subsequent thereto. The preset subsequent time may be set according to the predetermined time in any one of the first to fourth embodiments, and specifically, may be set to a value (for example, 20ms) obtained by subtracting the minimum detection period (for example, 10ms) of the detection unit 12 from the predetermined time (for example, 30 ms).
According to the electronic apparatus 1 of the present embodiment, when the operation direction of the sliding operation of the touch panel by the user is changed and an operation point deviated from the previous direction appears, it is possible to easily determine whether the deviated point and the subsequent sliding operation are the valid operation desired by the user or the erroneous invalid operation based on the operation duration after the deviated operation point.
The present embodiment will be described with reference to specific examples. Fig. 10 is a schematic diagram of a specific example of the slide operation in the fifth embodiment of the present invention. As shown in fig. 10, the detection unit 12 continuously detects coordinates of 7 contact points S to E as information of the operation point at a minimum cycle (10 ms). And acquiring the moving track of the finger according to the information of the continuous operation points, determining that the sliding operation of the user is accepted, and executing the corresponding function. Specifically, one sliding operation may be decomposed into a falling point S (start contact point), a rising point E (final contact point), and several moving points that are successively detected therebetween with a minimum cycle of the detection section 12. The operation direction estimating unit 13 estimates the operation direction of the slide operation from the slide locus connecting the continuous operation points. As shown in fig. 10, since the operation point T is deviated from the previous operation direction (the direction of S to R), the determination unit 14 determines whether or not the sliding operation is finished at a subsequent time (20ms) after the operation point T. Since the detection unit 12 detects the operation point E10 ms after the operation point T and does not detect the operation point thereafter, the determination unit 14 determines that the sliding operation is completed within a subsequent time (20ms) after the operation point T. The operation reception control unit 15 invalidates the operation point T and the operation point E following the operation point T in the slide operation, and outputs the display screen or the display information only in the scroll direction corresponding to the operation direction of the operation points S to R.
In the present embodiment, the determination unit 14 may determine whether or not the sliding operation is finished within a predetermined subsequent time after the deviated operation point by determining whether or not the operation point after the deviated operation point is smaller than a predetermined number. The predetermined number may be set based on the preset succeeding time and the minimum detection period of the detection unit 12, and may be set to, for example, a value (2) obtained by dividing the preset succeeding time (20ms) by the minimum detection period (10ms) of the detection unit 12. As shown in fig. 10, since the operation point after the deviated operation point T is the only operation point E, the number is 1 and is smaller than the predetermined number (2), the determination unit 14 determines that the slide operation is ended within the predetermined subsequent time after the deviated operation point. Thus, by a simple process of determining the number of operation points subsequent to the deviated operation point, it is possible to determine whether the sliding operation at the deviated point and subsequent thereto is a valid operation desired by the user or an erroneous invalid operation, thereby reducing the processing load of the electronic apparatus 1.
In the present embodiment, the operation direction estimating unit 13 may estimate the operation direction of the slide operation by correcting the direction in which the adjacent operation points are connected, based on the distance between the plurality of operation points continuously detected by the detecting unit 12 and the increase or decrease in the coordinates between the plurality of operation points. As shown in fig. 10, since the X coordinate significantly increases from the operation point S to the operation point R and the Y coordinate increases but the distance in the Y direction between the adjacent detection points is small, the operation direction estimating unit 13 corrects the direction connecting the operation points from the operation point S to the operation point R to the horizontal direction as the estimated operation direction desired by the user. In this way, in the case where the operation direction of the user deviates from the desired direction to some extent, the direction actually desired by the user can be estimated as much as possible, and the display screen or the display information desired by the user can be output accordingly.
The above description specifically describes an example in which the present embodiment is applied to the first embodiment, but the present embodiment is not limited to this, and the present embodiment can be applied to any one of the first to fourth embodiments.
