Description

Display device

This invention relates to a display device provided with a touch panel.

In recent years, in-vehicle systems that control devices in a vehicle by attaching a display device including a touch panel to an instrument panel of the vehicle and operating the touch panel have become widespread. However, since it is necessary for the driver to focus on driving while the vehicle is traveling, there are many cases where the driver cannot perform complicated operations on the touch panel.
On the other hand, for example, in Patent Document 1, in addition to a normal touch operation, an operation unit that captures a driver's hand movement (gesture) with a camera and displays it on a display screen based on the captured information. An apparatus for discriminating an operation on is disclosed. By doing so, the operation input is simplified.

The display device 1 does not limit the operations that can be accepted by the operation unit 3a, but restricts the operations that the operation unit 4 can accept.

The movement detection unit 5A is a detection unit that detects the movement of the moving body, and includes a GPS reception unit 8 and a built-in acceleration sensor 9. The GPS (Global Positioning System) receiving unit 8 receives GPS radio waves from GPS satellites via the GPS antenna 8a, analyzes the GPS radio waves, acquires position information (latitude / longitude) of the moving object, and periodically acquires it. It is determined whether or not the moving object is moving from the change state of the position information.

The built-in acceleration sensor 9 is a sensor that is built in the moving body and determines whether the moving body is in a moving state (moving) or in a stopped state from the detected acceleration value.
The movement detection unit 5A may finally determine whether or not the moving body is moving from the results obtained by both the GPS reception unit 8 and the built-in acceleration sensor 9, or the GPS reception unit 8 and the built-in acceleration sensor 9 may be provided.

FIG. 2 (b) shows the display device 1 that is connected to the movement detection unit 5B, which is an in-vehicle information device, and acquires information indicating whether or not the moving object is moving. For example, a usage mode in which a user carrying the display device 1 of FIG. 2B brings the display device 1 into the vehicle and connects to the movement detection unit 5B which is an in-vehicle device is conceivable.

The movement detection unit 5B is realized by, for example, the in-vehicle multimedia device 11 as shown in FIG. The in-vehicle multimedia device 11 is an in-vehicle information device that is mounted on a vehicle and functions as a car navigation system or an AV system.

Also, the in-vehicle multimedia device 11 receives GPS radio waves from GPS satellites via the in-vehicle GPS antenna 12, analyzes the GPS radio waves, acquires position information of the moving object, and periodically acquires the position information acquired. It is determined whether or not the moving object is moving from the change state.
Furthermore, the in-vehicle multimedia device 11 receives a vehicle speed pulse signal from an ECU (electronic control unit) of the vehicle, and determines whether or not the moving body (vehicle) is moving from the change in the vehicle speed pulse signal.

The movement detection unit 5B may finally determine whether or not the moving body is moving from both the determination result by the GPS signal and the determination result by the vehicle speed pulse signal, or by using the GPS signal. What is necessary is just to be provided with at least one of the function which judges the presence or absence of a movement, and the function which judges the presence or absence of a movement with a vehicle speed pulse signal.

FIG. 2C shows a case where the display device 1 according to Embodiment 1 is applied as one in-vehicle information device. For example, a usage mode in which the display device 1 in FIG. 2C is an in-vehicle information device with a display device mounted on an instrument panel of a vehicle is conceivable.

It is determined whether or not the moving body is moving from the change state.
Further, the in-vehicle multimedia function unit 13 receives a vehicle speed pulse signal from an ECU (electronic control unit) of the vehicle, and determines whether or not the moving body (vehicle) is moving from the change in the vehicle speed pulse signal.

The in-vehicle multimedia function unit 13 may finally determine whether or not the moving body is moving from both the determination result by the GPS signal and the determination result by the vehicle speed pulse signal, or You may be provided with at least one of the function which judges the presence or absence of a movement with a GPS signal, and the function which judges the presence or absence of a movement with a vehicle speed pulse signal.

Next, the operation will be described.
FIG. 3 is a flowchart showing the operation of the display device according to the first embodiment, and details of the operation limiting operation depending on whether or not the moving body is moving will be described with reference to FIG. Here, a case where the display device 1 is mounted on a vehicle and the movement detection unit 5 detects the movement of the vehicle is taken as an example.
First, in the display device 1, the movement detection unit 5 always detects whether the vehicle on which the display device 1 is mounted is moving or stopped (step ST1). Here, if the vehicle is stopped (step ST1; stopping), the movement detection unit 5 transmits stop detection information to the control unit 7.
When the control unit 7 receives the vehicle stop detection information from the movement detection unit 5, the control unit 7 instructs the display unit 6 to display a stop screen and functions (step ST2).

FIG. 4 is a diagram illustrating an example of operations that can be accepted when the moving body is stopped. When the vehicle is stopped, that is, when the user can focus on the operation, the control unit 7 touches with one finger (operation object) as shown in FIGS. 4 (a) and 4 (b). In addition to the operation, a touch operation using two fingers (operation object) as shown in FIGS. 4C and 4D can be accepted by the operation unit 4.
For example, when the map is displayed on the display area 3 while the vehicle is stopped and the finger is touched with two fingers in the touch operation area of the operation unit 4, an operation of spreading two fingers at the same time (step) ST3: With operation) As a function corresponding to this operation, the map display in the display area 3 is enlarged (step ST4). Further, when sound is output from the display device 1, it is also possible to adjust the volume by an operation of sliding the touch operation area of the operation unit 4 from a state of being touched with one finger.

In this way, the control unit 7 can accept the operation unit 4 by determining that the user can focus on the operation if the vehicle (moving body) is stopped, and that a complicated operation can be performed without taking time. Does not restrict the operation. If there is no operation on the operation unit 4 (step ST3; no operation), the process returns to step ST1.

On the other hand, if the vehicle is moving (step ST1; moving), the movement detector 5 transmits movement detection information to the controller 7.
When receiving the vehicle movement detection information from the movement detection unit 5, the control unit 7 instructs the display unit 6 to display a screen and functions for movement (step ST5).

FIG. 5 is a diagram illustrating an example of an operation that can be accepted when the moving body is moving. When the vehicle is moving, that is, when there is a possibility that the user cannot focus on the operation, the control unit 7 uses one finger (operation object) as shown in FIGS. 5 (a) and 5 (b). The touch operation using is accepted, but the touch operation using two fingers (operation article) as shown in FIG. 5C and FIG.
For example, when an operation of sliding the touch operation area of the operation unit 4 from a state of being touched with one finger while performing voice output on the display device 1 (step ST6; with operation), the control unit 7 Then, it is determined whether the executed operation is an acceptable operation or an unacceptable operation (step ST7). At this time, since the executed operation is a simple slide operation that completes the processing regardless of the screen display, the control unit 7 determines that the operation is acceptable (step ST7; acceptable operation), The volume is adjusted according to the slide operation (step ST8). The slide operation may be adjusted so that the volume is increased or decreased according to the slide amount. Alternatively, it may be adjusted so as to increase or decrease by a predetermined amount (for example, one level) in accordance with one slide operation. Furthermore, in this case, when the speed of the slide operation is an operation equal to or higher than a predetermined speed, the predetermined amount that changes may be increased as compared with the case of the slide operation less than the predetermined speed (for example, three levels).

On the other hand, when the executed operation is an operation in which two fingers are simultaneously spread from a state in which the touch operation area of the operation unit 4 is touched with two fingers, the control unit 7 displays the operation on the screen (map display). Since it is a complicated operation that is executed while visually confirming the scale, it is determined that the operation cannot be accepted (step ST7; an operation that cannot be accepted).
In this case, the control unit 7 presents to the user that the executed operation is an unacceptable operation (step ST9), and does not execute the functional operation corresponding to the operation.
Thus, the convenience can be further improved by presenting to the user that the operations that can be accepted by the operation unit 4 are limited because the vehicle is moving.
In FIG. 5, the control unit 7 instructs the display unit 6 to display, in the display area 3, a mark 14 indicating that the operations that can be accepted by the operation unit 4 are limited by movement detection. The user can grasp that the operations that can be accepted by the operation unit 4 are limited by referring to the mark 14. As a result, an operation that has become unacceptable by the user is not performed wastefully.
In addition to displaying the mark 14, the frame portion of the display area 3 may be displayed in a color or a light emission pattern different from that during the stop, or may be notified by voice.

Thus, since the user cannot focus on the operation when the vehicle (moving body) is moving, the control unit 7 determines that the operation is time-consuming if it is a complicated operation, and that the usability is deteriorated. The operations that can be accepted by the operation unit 4 are limited. When there is no operation on the operation unit 4 (step ST6; no operation), the process returns to step ST1.

An operation using two fingers (operation object) is generally performed while confirming the operation result on the display screen, and therefore cannot be accepted when the moving body is moving.
That is, according to the present invention, during the movement of the moving body, the control unit 7 displays the operation result in the display area 3 of the display unit 6, and performs the operation executed while visually recognizing the operation result. Make it unacceptable. For example, even if the operation is performed using one finger (operation article), a handwriting input operation or the like is not accepted. Further, even if the operation itself is a simple slide operation, the scrolling of the screen that needs to be visually recognized cannot be accepted.

In the above description, the case where the operations that can be accepted by the operation unit 4 are limited when the moving body (vehicle) is moving is shown, but the present invention is not limited to this. That is, when the speed of the moving body is higher than the predetermined speed, the operations that can be accepted are limited as compared with the case where the speed of the moving body is equal to or lower than the predetermined speed. For example, the predetermined speed is 5 km / h or the like, and the restriction is not performed in the case of a low speed where the vehicle is considered to be substantially stopped. In addition, when the operation state of the hand brake or foot brake of the vehicle can be obtained by in-vehicle LAN or communication, it may be detected whether the vehicle is substantially in a stop state according to these operation states.

As described above, according to the first embodiment, the display device 1 is provided on the display unit 6 and the display surface side of the display unit 6 and has a touch operation area wider than the display area of the display unit 6. When the speed of the touch panel 2 in which the operation unit 4 that accepts a touch operation in the area is formed in an area corresponding to the outside of the display area 3 of the display unit 6 and the moving body is faster than a predetermined speed, the movement And a control unit 7 that limits operations that can be received by the operation unit 4 when the body speed is equal to or lower than a predetermined speed. By comprising in this way, operation according to the movement state of the moving body carrying or carrying the display apparatus 1 is received, operativity can be improved, and misoperation can be reduced.

Further, according to the first embodiment, when the speed of the moving body is higher than the predetermined speed, the control unit 7 makes the operation unit 4 unacceptable for operations performed with a plurality of operating objects. Since a complicated operation is not performed in a state where no power can be applied, the operability of the operation unit 4 is improved and erroneous operations can be reduced.

Further, according to the first embodiment, when the speed of the moving body is higher than the predetermined speed, the control unit 7 displays the operation result in the display area 3 of the display unit 6 and visually recognizes the operation result. Since the operation to be executed is not accepted by the operation unit 4, similarly, a complicated operation is not performed in a state where the user cannot focus on the operation, so that the operability of the operation unit 4 is improved and erroneous operations are reduced. be able to.

Furthermore, according to the first embodiment, when the speed of the moving body is higher than a predetermined speed, the control unit 7 performs a complicated gesture operation using two or more fingers performed with the operation article. Therefore, it is possible to reduce the occurrence of an erroneous operation when the user cannot focus on the operation. At this time, an operation is accepted for a simple gesture operation performed with one finger.

Furthermore, according to the first embodiment, since the control unit 7 presents to the user that the operations that can be accepted by the operation unit 4 are limited, an unnecessary operation that cannot be accepted by the user is not performed. The convenience of the operation unit 4 can be improved.

In the present invention, any component of the embodiment can be modified or any component of the embodiment can be omitted within the scope of the invention.

The display device according to the present invention is suitable for a display device of an in-vehicle information device that needs to focus on driving, such as during traveling, because operability is improved and erroneous operation can be reduced.
