Description

Input device and control program

The present invention relates to an input device and a control program having an operation unit for detecting an object in contact or proximity.

In recent years, mobile terminals such as smartphones and tablet terminals having touch panels are increasing. Also, as shown in FIG. 9, a portable terminal 100 has been developed in which a touch panel 102 is extended outside the display unit, and a key unit 103 that is conventionally configured with physical buttons or the like is configured with a touch panel.

In such a portable terminal 100 in which the key unit 103 is configured by the touch panel 102, the user may erroneously touch the key unit 103 outside the display unit 101 when operating on the display unit 101. Therefore, a technique for invalidating such an erroneous operation (for example, a technique described in Patent Document 1) has been developed.

Japanese Patent Publication “Japanese Patent Laid-Open No. 2012-248068 (Released on December 13, 2012)” Japanese Patent Publication “JP-A-7-168664 (published July 4, 1995)” Japanese Patent Publication “Japanese Patent Laid-Open No. 2005-11233 (published on January 13, 2005)”

Here, the team of the present inventors has developed a mobile phone 200 having a narrow frame with a narrow frame area as shown in FIG. 10, compared with the conventional mobile terminal 100 shown in FIG. Since the conventional mobile terminal 100 has a wide frame area 110, a space necessary for arranging the sensor lines can be secured. However, when the operation unit 202 and the key unit 203 on the display unit 201 are configured with a single touch panel, the mobile phone 200 with a narrow frame has a narrow frame area 210, so that a space necessary for arranging sensor lines is not provided. It is difficult to secure.

Therefore, as shown in FIG. 2, the team of the present inventors has developed a mobile phone 1 in which the key unit 15 is configured with a touch panel that does not acquire coordinate values (for example, an electrostatic button method). Thereby, the cellular phone 1 can secure a sufficient space for arranging the sensor lines in the frame region 30.

In such a cellular phone 1 in which the first operation unit 14 on the display unit 13 and the key unit 15 are configured by different devices, the key unit 15 is not intended to operate the first operation unit 14. There is a possibility that an erroneous operation will occur.

Here, in Patent Document 1, since the operation unit on the display unit and the key unit are configured with the same touch panel, the control unit integrally grasps the input from the operation unit and the key unit on the display unit. And exclusive control is easy.

However, since the mobile phone 1 in which the first operation unit 14 and the key unit 15 are configured by different devices is difficult to grasp the two inputs in a unified manner, the erroneous operation described in Patent Document 1 is invalid. The technology cannot be applied as it is.

The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a first operation unit and a second operation unit that are disposed in close proximity to each other, and detect a contact or an adjacent object. An input device including a first operation unit and a second operation unit is to realize an input device and a control program that invalidate a user's erroneous operation.

In order to solve the above-described problem, an input device according to an aspect of the present invention is a first operation unit and a second operation unit that are arranged close to each other, and detects a first object that is in contact with or close to the first operation unit. An input device including an operation unit and a second operation unit, wherein a first event generation that generates a first operation event indicating a content of a user operation on the first operation unit based on a signal from the first operation unit Means, second event generation means for generating a second operation event indicating the user's operation content on the second operation unit based on a signal from the second operation unit, the first operation event, and the second operation event. A determination unit configured to determine whether the operation event is valid or invalid; and an output unit configured to output the first operation event and the second operation event determined to be valid. It said determination means determines to be invalid the second operating events generated during a series of operations in the first operation section is being performed.

According to one aspect of the present invention, it is possible to invalidate a user's erroneous operation and prevent an unintended process from being executed.

[Summary of the Invention]
The present invention provides an input device including a first operation unit and a second operation unit that are arranged close to each other, and that includes a first operation unit and a second operation unit that detect an object (indicator) that is in contact with or close to the first operation unit. This is to invalidate the user's erroneous operation.

In the present invention, when the user performs a drag operation on the display unit 13 (first operation unit 14) and this drag operation goes too far to contact the second operation unit 15, the user performs the display unit 13 (first operation unit 14). ) It is assumed that there are two erroneous operation cases in which the user accidentally touches the second operation unit 15 first while trying to perform a drag operation.

Hereinafter, the present invention will be described by exemplifying a mobile phone including the input device according to the present invention. However, the application target of the present invention is not limited to the mobile phone, and any electronic device may be used. For example, electronic devices such as a tablet terminal, a portable music player, a portable game machine, a PC, a television, a digital camera, a digital video camera, and a remote controller may be used.

An embodiment of the present invention will be described with reference to FIGS. 1 to 8 as follows.

[Configuration of mobile phone]
FIG. 1 is a block diagram illustrating an example of a main configuration of the mobile phone 1. As shown in FIG. 1, the mobile phone 1 includes a control unit 11, a storage unit 12, a display unit 13, a first operation unit 14, and a second operation unit 15. The mobile phone 1 may include members such as a communication unit, a voice input unit, and a voice output unit, but these members are not shown because they are not related to the features of the invention.

The display unit 13 displays an image in accordance with instructions from the control unit 11. The display unit 13 only needs to display an image in accordance with an instruction from the control unit 11. For example, an LCD (liquid crystal display), an organic EL display, a plasma display, or the like can be applied.

The first operation unit 14 is for a user to input an operation signal to the mobile phone 1 and operate the mobile phone 1. Specifically, the first operation unit 14 is an operation unit integrated with the display unit 13, a so-called touch panel. The first operation unit 14 detects that an object such as a user's finger has touched or approached, and outputs the detection result.

The first operation unit 14 outputs a first operation signal indicating the detection of the object and the detected position (coordinates) to the control unit 11 as a detection result.

The second operation unit 15 is for a user to input an operation signal to the mobile phone 1 and operate the mobile phone 1. Specifically, the second operation unit 15 is a device different from the first operation unit 14. The second operation unit 15 detects that an object such as a user's finger has touched or approached, and outputs the detection result.

In the present embodiment, the second operation unit 15 is a key unit arranged outside the display unit 13 and includes three keys, a home key, a back key, and a menu key. However, the type and number of keys are arbitrary, and the second operation unit 15 may be configured by one or a plurality of keys.

The second operation unit 15 outputs, as a detection result, a second operation signal indicating that the object has been detected and the detected key type to the control unit 11. The second operation unit 15 may output a second operation signal indicating only that an object has been detected. Further, the position (coordinates) where the second operation signal is detected may be included.

In addition, the detection method of the 1st operation part 14 and the 2nd operation part 15 may be arbitrary. Further, the first operation unit 14 and the second operation unit 15 may be able to detect a plurality of objects at the same time. In this case, the mobile phone 1 can individually track the positions of the detected plurality of objects.

The control unit 11 performs various calculations by executing a program read from the storage unit 12 to a temporary storage unit (not shown), and comprehensively controls each unit included in the mobile phone 1. .

In the present embodiment, the control unit 11 includes, as functional blocks, a touch event generation unit (first event generation unit) 21, a key event generation unit (second event generation unit) 22, and an event interpretation unit (determination unit, output unit). 23 and a function execution unit 24. Each function block (21 to 24) of the control unit 11 includes a program stored in a storage device realized by a CPU (central processing unit), a ROM (read only memory), and the like (random access memory). This can be realized by reading out and executing the temporary storage unit realized by the above.

The touch event generation unit 21 acquires a first operation signal from the first operation unit 14, and based on the acquired first operation signal, a touch event (first operation event) indicating a user operation content on the first operation unit 14 is obtained. ). The touch event generation unit 21 generates a touch down event (first operation down event), a touch up event (first operation up event), or a touch move event (first operation move event). The touch-down event indicates that an object has contacted or approached the first operation unit 14, the touch-up event indicates that the object has left the first operation unit 14, and the touch-moving event represents the first operation unit 14. Indicates that the object has moved while the object is in contact with or close to the object. Note that the touch event generation unit 21 generates a touch event by adding information indicating the detected position.

The key event generation unit 22 acquires a second operation signal from the second operation unit 15, and based on the acquired second operation signal, a key event (second operation event) indicating a user operation content on the second operation unit 15. ). The key event generation unit 22 generates a key down event (second operation down event) or a key up event (second operation up event). The key-down event indicates that an object has touched or approached the second operation unit 15, and the key-up event indicates that the object has left the second operation unit 15. The key event generation unit 22 generates a key event by adding information indicating the type of the detected key.

The event interpretation unit 23 acquires the touch event generated by the touch event generation unit 21 and the key event generated by the key event generation unit 22, and determines whether the acquired touch event and key event are valid or invalid. Then, the touch event and the key event determined to be valid are output to the function execution unit 24 as output events.

Specifically, the event interpretation unit 23 determines that the acquired touch event or key event is valid, and outputs it as an output event as it is, except for the following predetermined cases. However, the event interpretation unit 23 determines that the key event generated by the key event generation unit 22 is invalid during a period in which a series of operations are performed on the first operation unit 14. That is, the event interpretation unit 23 does not output a key event generated during a period in which a series of operations are performed on the first operation unit 14 as an output event.

The event interpretation unit 23 performs a series of operations on the first operation unit 14 from when the touch event generation unit 21 generates a touchdown event until it generates a touchup event corresponding to the touchdown event. Period. Similarly, a series of operations are performed on the second operation unit 15 from when the key event generation unit 22 generates a key down event to when a key up event corresponding to the key down event is generated. Period.

Here, the touch-up event corresponding to the touch-down event is a touch that occurs when the indicator that has generated the touch-down event (for example, a finger that operates the touch panel) next moves away from the first operation unit 14. It is an up event.

Similarly, the key-up event corresponding to the key-down event occurs when the indicator (for example, a finger that operates the touch panel) that generated the key-down event next moves away from the second operation unit 15. It is a key up event.

In addition, when the key event generation unit 22 generates a key-up event during a period in which a series of operations are performed on the first operation unit 14, the event interpretation unit 23 determines that the key-up event is invalid. Further, a key cancel event (second operation cancel event) for canceling the key down event corresponding to the key up event is generated and output as an output event.

In addition, when the key event generation unit 22 generates a key down event during a period when a series of operations are performed on the first operation unit 14, the event interpretation unit 23 determines that the key down event is invalid. Furthermore, it is determined that the key-up event corresponding to the key-down event generated after the period has passed is also invalid.

In addition, when the touch event generation unit 21 generates a touch event during a period in which a series of operations are performed on the second operation unit 15, the event interpretation unit 23 selects a key based on the series of operations on the second operation unit. It is determined that the event (key down event and key up event) is invalid.

The function execution unit 24 executes a predetermined function of the mobile phone 1 based on the output event output from the event interpretation unit 23.

The storage unit 12 stores programs, data, and the like referred to by the control unit 11.

A device including the first operation unit 14, the second operation unit 15, the touch event generation unit 21, the key event generation unit 22, and the event interpretation unit 23 is referred to as an input device 2. That is, the mobile phone 1 includes an input device 2 and executes a predetermined function based on an output event output from the input device 2.

[Processing of input device]
Next, processing of the input device 2 will be described with reference to FIGS. Here, the process of the input device 2 will be described separately for a case where the user first contacts the first operation unit 14 and a case where the user first contacts the second operation unit 15. FIG. 3 is a flowchart illustrating an example of processing of the input device 2 when the user first contacts the first operation unit 14. FIG. 4 is a flowchart illustrating an example of processing of the input device 2 when the user first contacts the second operation unit 15.

First, based on FIG. 3, the process of the input device 2 when the user first contacts the first operation unit 14 will be described.

As shown in FIG. 3, when the user first contacts the first operation unit 14, the first operation unit 14 outputs a first operation signal to the touch event generation unit 21, and the touch event generation unit 21 generates a touchdown event. Generate (S1). Then, the event interpretation unit 23 determines that the touchdown event generated by the touch event generation unit 21 is valid, and outputs it as it is (S2).

The event interpretation unit 23 waits for the next event to be generated (S3). If the next generated event is a touch-up event (YES in S4), the touch event generated by the touch event generation unit 21 is displayed. It determines with it being effective, outputs as it is (S5), and complete | finishes a process.

If the next generated event is a touch move event (NO in S4 and NO in S6), it is determined that the touch move event generated by the touch event generating unit 21 is valid and is output as it is (S8). , The process returns to S3.

When the next event generated is a key event (key down event or key up event) (NO in S4 and YES in S6), the event interpreter 23 invalidates the key event generated by the key event generator 22. The key event is not output (S7), and the process returns to S3.

In S6, when a key-down event is generated and a key-up event corresponding to the key-down event is generated after the generation of the touch-up event, the event interpretation unit 23 selects the key-up event corresponding to the key-down event. The event is determined to be invalid and the key-up event is not output.

Next, processing of the input device 2 when the user first contacts the second operation unit 15 will be described with reference to FIG.

As shown in FIG. 4, when the user first contacts the second operation unit 15, the second operation unit 15 outputs a second operation signal to the key event generation unit 22, and the key event generation unit 22 generates a key down event. Generate (S11). Then, the event interpretation unit 23 determines that the key down event generated by the key event generation unit 22 is valid, and outputs it as it is (S12).

The event interpretation unit 23 waits for the next event to be generated (S13). If the next generated event is a key-up event (YES in S14), the event interpretation unit 23 displays the key-up event generated by the key event generation unit 22. It determines with it being effective, outputs as it is (S15), and complete | finishes a process.

On the other hand, when the event generated next is a touchdown event (NO in S4), the event interpretation unit 23 determines that the touchdown event generated by the touch event generation unit 21 is valid, and outputs it as it is ( (S16) A key cancel event for canceling the previously output key down event is generated and output (S17).

Then, the event interpretation unit 23 determines that the key-up event corresponding to the previously output key-down event generated by the key event generation unit 22 is invalid and does not output it, and the touch event generation unit 21 generates it. It is determined that the touch event is valid and is output as it is (S18). The event interpretation unit 23 outputs a touch-up event corresponding to the touch-down event in S16, and ends the process.

[Example 1]
Next, a specific processing example (Example 1) for preventing the mobile phone 1 from malfunctioning will be described with reference to FIGS. Here, a case will be described in which the user performs a drag operation on the display unit 13 (first operation unit 14), and the drag operation goes too far to contact the second operation unit 15. FIG. 5 is a diagram illustrating a user's erroneous operation. FIG. 6 is a diagram showing events that occur and the order in which they occur.

As illustrated in FIG. 5, when the user performs a drag operation on the display unit 13 from the top to the bottom, the drag operation goes beyond the area of the display unit 13 and the user unintentionally contacts the second operation unit 15. There is a case.

At this time, as shown in FIG. 6, a touchdown event is first generated, and a touch move event is generated by a user's drag operation. When the user's finger is placed at the boundary between the display unit 13 and the frame of the mobile phone 1, the user's finger contacts both the first operation unit 14 and the second operation unit 15. Therefore, as shown in FIG. 6, the key down event occurs before the touch up event occurs.

In this case, since the event interpreter 23 is a key event that occurs during a series of touch events, the event interpreter 23 invalidates the event without outputting this key-down event. Furthermore, the event interpreter 23 also invalidates a key-up event corresponding to the invalid key-down event that occurs thereafter.

Since such processing is performed, as shown in FIG. 5, even when the user unintentionally operates the second operation unit 15, the mobile phone 1 does not execute a predetermined function due to this erroneous operation. , Malfunction can be prevented.

[Example 2]
Next, a case where the user mistakenly touches the second operation unit 15 first when trying to perform a drag operation on the display unit 13 (first operation unit 14) will be described with reference to FIGS. FIG. 7 is a diagram illustrating an erroneous operation by the user. FIG. 8 is a diagram showing events that occur and the order in which they occur.

As shown in FIG. 7, when the user performs a drag operation on the display unit 13 from the bottom to the top, the finger may accidentally contact the second operation unit 15 first.

At this time, as shown in FIG. 8, a key-down event is first generated, and a touch-down event and a touch-move event are generated by a user's drag operation. When the user's finger leaves the second operation unit 15, a key-up event occurs.

Thus, when a touch event occurs between a series of key events, the event interpretation unit 23 invalidates the series of key events. The event interpreter 23 outputs a key cancel event for canceling the key down event because it outputs the key down event before invalidating. Also, the key up event is not output and is invalidated.

Since such processing is performed, as illustrated in FIG. 7, even when the user unintentionally operates the second operation unit 15, the mobile phone 1 does not execute a predetermined function due to this erroneous operation. , Malfunction can be prevented.

[Example 3 (example realized by software)]
The control block (particularly the control unit 11) of the mobile phone 1 may be realized by a logic circuit (hardware) formed in an integrated circuit (IC chip) or the like, or by software using a CPU (Central Processing Unit). It may be realized.

In the latter case, the mobile phone 1 includes a CPU that executes instructions of a program that is software that realizes each function, a ROM (Read Only Memory) in which the program and various data are recorded so as to be readable by a computer (or CPU), or A storage device (these are referred to as “recording media”), a RAM (Random Access Memory) for expanding the program, and the like are provided. And the objective of this invention is achieved when a computer (or CPU) reads the said program from the said recording medium and runs it. As the recording medium, a “non-temporary tangible medium” such as a tape, a disk, a card, a semiconductor memory, a programmable logic circuit, or the like can be used. The program may be supplied to the computer via an arbitrary transmission medium (such as a communication network or a broadcast wave) that can transmit the program. The present invention can also be realized in the form of a data signal embedded in a carrier wave in which the program is embodied by electronic transmission.

[Summary]
An input device according to an aspect 1 of the present invention includes a first operation unit and a second operation unit that are arranged in close proximity to each other, and include a first operation unit and a second operation unit that detect an object that is in contact with or close to the input unit. An input device, based on a signal from the first operation unit, from a first event generation unit that generates a first operation event indicating a user operation content on the first operation unit, and from the second operation unit And a second event generation means for generating a second operation event indicating a user's operation content on the second operation unit, and whether the first operation event and the second operation event are valid or invalid. Determination means for determining whether or not there is output means for outputting the first operation event and the second operation event for which the determination means is determined to be effective, and the determination means includes the first operation event Determined to be invalid the second operating events generated during a series of operations are performed.

The operation on the second operation unit performed during a period in which a series of operations are performed on the first operation unit is considered to be an erroneous operation by the user. Therefore, when the determination unit determines that the second operation event generated during a period in which a series of operations are performed on the first operation unit is invalid, the output unit causes the second operation event due to a user's erroneous operation. 2 Do not output operation events. That is, the user's erroneous operation can be invalidated.

The input device according to aspect 2 of the present invention is the input apparatus according to aspect 1, in which the determination unit determines that the object has moved from the generation of the first operation down event indicating that the object has contacted or approached the first operation unit. The period until the generation of the first operation up event indicating the separation from the first operation unit may be a period during which a series of operations are performed on the first operation unit.

The input device according to aspect 3 of the present invention is the input device according to

aspect

1 or 2, wherein the object is separated from the second operation unit during a period in which a series of operations are performed on the first operation unit. When the two-operation up event is generated, the determination unit determines that the second operation up event is invalid, and the output unit indicates that the object is in contact with or close to the second operation unit. A second operation cancel event that cancels the second operation down event corresponding to the second operation up event that is determined to be invalid by the determination unit may be output.

As described above, it is considered that the second operation up event generated during a period in which a series of operations are performed on the first operation unit is caused by an erroneous operation of the user. Therefore, the second operation down event corresponding to the second operation up event is also due to an erroneous operation of the user. Therefore, the second operation down event corresponding to the second operation up event generated during a period in which a series of operations are performed on the first operation unit should be invalidated even if it is not generated within the period. Kimono.

In addition, since the second operation down event is generated before the period, it is output as an output event as it is. Therefore, it is necessary to invalidate the second operation down event that has already been output.

Therefore, as described above, the output means outputs the second operation cancel event for canceling the second operation down event corresponding to the second operation up event, thereby reliably invalidating the event due to the erroneous operation of the user. can do.

In the input device according to aspect 4 of the present invention, in any one of the aspects 1 to 3, the determination unit generates a second operation down event during a period in which a series of operations are performed on the first operation unit. If it is, the second operation up event corresponding to the second operation down event generated after the above period may be determined to be invalid.

As described above, it is considered that the second operation down event generated during a period in which a series of operations are performed on the first operation unit is caused by an erroneous operation of the user. Therefore, the second operation up event corresponding to the second operation down event is also due to an erroneous operation of the user. Therefore, the second operation up event corresponding to the second operation down event generated during a period in which a series of operations are performed on the first operation unit should be invalidated even if it is not generated within the period. Kimono.

Therefore, as described above, the determination unit determines that the second operation up event corresponding to the second operation down event is invalid, and the output unit does not output the second operation up event. Therefore, an event caused by a user's erroneous operation can be surely invalidated.

The input device according to each aspect of the present invention may be realized by a computer. In this case, the input device is realized by the computer by causing the computer to operate as each unit included in the input device.
