The present invention mainly relates to a device having a touch panel, which is able to display an image and a symbol arranged on the image.
Conventionally, devices having touch panels (hereinafter, may simply be referred to as the touch panel devices) which can recognize touches at two or more positions have been known. Patent Document 1 discloses a method of performing predetermined processing with such kind of touch panel device, a touch pad and the like according to touch operation contents (touch gestures), and discloses specific examples of the predetermined processing.
In Patent Document 1, a touch gesture of moving three-point touches (a thumb, an index finger, and a middle finger) close to each other is illustrated, and cut processing performed in response to this touch gesture is described. Moreover, the touch gesture of moving the three-point touches away from each other is also illustrated, and paste processing performed in response to this touch gesture is described (see the paragraph 0174 and
Moreover, in the paragraphs 0145, 0146 and 0150, a specific flow of performing copy and paste processing by touch operation is described. According to the description, an operator first performs the touch operation or uses a mouse, to select an object to copy. Then, the operator performs a touch gesture to perform the copy processing. Next, the operator performs the touch operation or uses the mouse, to specify a position to paste. Then, the operator performs a touch gesture to perform the paste processing. By performing the operation described above, the copy and paste processing can be performed.
Moreover, in a case of moving an icon or the like on the display screen with touch operation, a method of moving the icon by touching the icon or the like over a predetermined period of time and then moving it without removing the hand from the display screen, is commonly known.
However, since the copy and paste processing of Patent Document 1 requires a plurality of times of operations, it may be troublesome to the operator depending on the object to perform the processing on.
Meanwhile, with the operation utilizing the touch over the predetermined time period, since the operator needs to wait for the predetermined time period, the operation cannot be performed promptly. Moreover, since the touch shorter than the predetermined time period is normally associated with other processing, the other processing may be performed mistakenly when moving the icon.
Note that, the above problems are common, not only when performing copy processing and moving an icon, but through all kinds of operations performed by selecting a symbol (in the concept including an icon, a mark, etc.) in touch operation.
The present invention is made in view of the above situations and aims to provide a touch panel device which is able to select one or more symbols with operation which is simple and with which mistakes hardly occur.
Problems to be solved by the present invention are described above, and means for solving the problems and effects thereof will be described below.
According to a first aspect of the present invention, a device having a touch panel with the following configuration is provided. That is, the device having the touch panel includes a display unit, a detector, and a controller. The display unit displays, on a display screen, an image and symbols arranged on the image. The detector detects touch operations at two or more positions on the display screen and touched positions thereof. The controller creates an area on the display screen based on the two or more touched positions detected by the detector, and specifies one or more of the symbols located within the created area.
Thus, the one or more symbols can be selected by the operation that is simple and with which mistakes hardly occur.
With the above device having the touch panel, among the one or more of the symbols within the created area, the controller is preferred to specify the symbol that is closest to a center of the area by differentiating the symbol from the other symbols.
Thus, a single symbol can be selected by the operation that is simple and with which mistakes hardly occur.
With the above device having the touch panel, the controller is preferred to set the touched positions used in creating the area to be latest positions of the touch operations at the two or more positions respectively.
Thus, an operator can adjust the one or more of the symbols to be selected by moving the touched positions even after touching the display screen.
With the above device having the touch panel, even after the detector no longer detects the touch operations, the controller is preferred to keep the one or more of the symbols specified, the one or more of the symbols located within the area that is created based on the latest touched positions.
Thus, the one or more of the symbols are kept specified even if the operator does not keep touching the display screen, and therefore, operability can be improved.
With the above device having the touch panel, the controller is preferred to perform, on the specified one or more of the symbols, either one of cut processing in which the one or more of the symbols are removed and saved temporarily, and copy processing in which the one or more of the symbols are copied.
Thus, the operator can specify the one or more of the target symbols for either one of the cut processing and the copy processing by the operation that is simple and with which mistakes hardly occur.
With the above device having the touch panel, when the touch operations are performed so that the two or more touched positions approach the one or more of the symbols, the controller is preferred to perform either one of the cut processing and the copy processing on the one or more of the symbols.
Thus, the operator can specify the one or more of the target symbols for either one of the cut processing and the copy processing by the operation that hardly interferes with other touch operation and is instinctive.
With the above device having the touch panel, after the controller performs either one of the cut processing and the copy processing, when touch operations are performed at two or more touched positions so that the positions are separated from a predetermined position, the controller is preferred to perform paste processing in which the one or more of the symbols are pasted to the predetermined position.
Thus, the operator can specify the position to be pasted to, by the operation that hardly interferes with other touch operation and is instinctive.
With the above device having the touch panel, when the touch operations are performed so that the two or more touched positions are separated from the one or more of the symbols, the controller is preferred to perform processing in which only the surrounding of the one or more of the symbols is displayed enlarged on the display unit.
Thus, it can be such that only the surrounding of the one or more of the symbols is displayed enlarged by the touch operation resembling pinch-out operation in which normal enlarge processing is performed (operation of touching the two positions and bringing the respective touched positions away from each other), and therefore, the operator can perform instinctive operation.
With the above device having the touch panel, it is preferred to have the following configuration. That is, the device includes a memory configured to store nautical chart information. The controller displays a position of a ship and the symbols on a nautical chart based on positional information received from a GNSS sensor.
Thus, the effect that the one or more of the symbols can be specified by the operation which is simple and with which mistakes hardly occur, can be exerted with ship instrument.
According to other aspects of the present invention, a radar apparatus, a plotter apparatus, and a ship network system each including the device having the touch panel, are provided.
Thus, the effects of the present invention can be exerted with radar apparatuses, plotter apparatuses, and ship network systems.
According to a second aspect of the present invention, the following symbol specifying method is provided. That is, the symbol specifying method includes displaying, on a display screen, an image and symbols arranged on the image. The symbol specifying method includes detecting touch operations at two or more positions on the display screen and touched positions thereof. The symbol specifying method includes creating an area on the display screen based on the two or more touched positions detected by the detecting the touch operations, and specifying one or more of the symbols located within the created area.
Thus, the one or more symbols can be selected by the operation that is simple and with which mistakes hardly occur.
According to a third aspect of the present invention, a symbol specifying program having the following configuration is provided. That is, the symbol specifying program causes a computer to display, on a display screen, an image and symbols arranged on the image. The symbol specifying program causes a computer to detect touch operations at two or more positions on the display screen and touched positions thereof. The symbol specifying program causes a computer to create an area on the display screen based on the two or more touched positions detected by the detecting the touch operations, and specify one or more of the symbols located within the created area.
Thus, the one or more of the symbols can be selected by the operation that is simple and with which mistakes hardly occur.
According to a fourth aspect of the present invention, a device having a touch panel with the following configuration is provided. That is, the device having the touch panel includes a display unit, a detector, and a controller. The display unit displays, on a display screen, an image and symbols arranged on the image. The detector detects touch operations on the display screen and a touched position thereof. The controller creates an area on the display screen based on the touched position detected by the detector, and specifies one or more of the symbols located within the created area.
Thus, the one or more of the symbols can be selected by the operation that is simple and with which mistakes hardly occur (including operation performed by touching a single position).
Next, one embodiment of the present invention is described with reference to the drawings.
The ship instrument network system 1 of this embodiment includes a plurality of ship instruments connected to a ship network 10. The ship instruments can exchange, for example, detected information via the ship network 10 with each other. As the standard of the ship network 10, LAN (Local Area Network) or CAN (Controller Area Network) can be adopted, for example.
As illustrated in
The touch panel device 11 is configured to create and display an image (sensor image) based on information detected by the other ship instruments (sensors), detect a touch operation on a display screen, and perform processing according to the detection result. Specifically, the touch panel device 11 includes a display unit 21, a user interface 22, a memory 23, a detector 24, and a controller 25.
The display unit 21 is comprised of, for example, a liquid crystal display, and can display the sensor image, various setting screens and the like on the display screen as described above.
The user interface 22 is, for example, comprised of a rotary key to which a clockwise or counterclockwise rotational operation can be performed, and a hardware key, such as a menu key or the like for calling out a menu screen. Note that, with the touch panel device 11, input and instruction can be performed by touch operation(s) on the display screen. Therefore, the number of keys of the user interface 22 can be reduced.
The memory 23 stores, for example, contents of program(s) to be executed by the controller 25, nautical chart information, and navigation route(s) set by an operator.
The detector 24 detects the touch operation performed on the display screen by the operator. In this embodiment, a projected capacitance system is used as a system for detecting the touch operation. This system is configured such that a plurality of electrodes with high transparency are disposed on a display panel and a touched position is detected based on a change of an electric capacity of each electrode caused when a fingertip approaches the panel. With this configuration, not only the touched position but also a finger motion in a touching state (change of the touched position) can be detected. Moreover, when two or more positions are touched simultaneously, the detector 24 can also detect the respective touched positions and changes of the respective touched positions. The touched position(s) and the change of the touched position(s) detected by the detector 24 are outputted to the controller 25. Note that, the system for detecting the touch operation is not limited to the projected capacitance system, and any other suitable system may be adopted. Moreover, other than the touch operation by a finger, a configuration in which a touch operation performed by a tapered stick-like member is detected may be adopted, for example.
The controller 25 creates the sensor image (a radar image, a nautical chart around the ship, etc.) based on stored contents in the memory 23 and information received from other ship instrument(s), and displays it on the display unit 21. The controller 25 receives information from a plurality of ship instruments and creates a plurality of sensor images. The controller 25 can switch a screen mode between a mode for displaying only one of the plurality of sensor images on the display screen (full screen mode) and a mode for dividing the display screen and displaying a plurality of sensor images thereon (divided screen mode, see
Moreover, the controller 25 performs matching between the change of the touched position detected by the detector 24 and predetermined touch operation contents (touch gestures), and thereby, identifies which touch gesture is performed by the operator. Then, the controller 25 performs processing corresponding to the identified touch gesture.
One specific example of the touch gestures includes a “drag operation.” The drag operation is a touch gesture of moving a touching finger (normally one finger) on the display screen to a predetermined direction without separating it from the display screen. Scrolling of the image is normally associated with this drag operation. Note that, the drag operation also includes an operation of quickly moving the finger while touching the display screen (flick operation), and the like. Moreover, another example of the touch gestures includes a “pinch operation.” The pinch operation is an operation of, without separating two touching fingers from the display screen, bringing the fingers close to each other (pinch in) or separating them from each other (pinch out). Processing of changing a scale of the image is normally associated with this pinch operation. Note that, the controller 25 can also identify other various touch gestures than the examples given above.
The GPS antenna 12 receives positioning signals from GPS satellites (GNSS satellites) and outputs them to, for example, the touch panel device 11 via the ship network 10. The controller 25 of the touch panel device 11 obtains a location of the ship (specifically, a location of the GPS antenna and a terrestrial reference absolute position) based on the positioning signals. Note that, a configuration in which the calculation for obtaining the location based on the positioning signals is performed on the GPS antenna 12 side and the ship location is outputted to the touch panel device 11 may be adopted.
The touch panel device 11 can exert a function as a navigation device based on the obtained ship location and the nautical chart information stored in the memory 23. Specifically, based on the acquired ship location and the nautical chart information stored in the memory 23, the controller 25 can superimpose the ship location on the nautical chart and display it on the display unit 21. Moreover, the controller 25 can obtain a ground speed and a trace of the ship by utilizing the ship location which changes with time, and display them on the display unit 21. Further, the controller 25 can create a navigation route and display it on the display unit 21 based on the operator's selecting of a destination and a waypoint (stopover point) with the touch operation (see a first sensor image 31 illustrated in
The radar antenna 13 transmits a microwave and receives a reflection wave from an object. The reflection wave is suitably signal-processed and then outputted to the touch panel device 11. The touch panel device 11 creates a radar image based on the reflection wave. Specifically, the controller 25 of the touch panel device 11 obtains a distance of the object based on a time length from the transmission of the microwave to the reception of the reflection wave. Moreover, the controller 25 obtains a direction in which the object exists, based on a direction to which the microwave is transmitted. The controller 25 creates the radar image as described above and displays it on the display unit 21 (see a second sensor image 32 illustrated in
The fish finder 14 is comprised of a transducer and an analyzer. The transducer is installed in, for example, the bottom of the ship, and discharges an ultrasonic wave directly below into the sea and receives the reflection wave from the sea bottom or a school of fish. The analyzer creates fish finding data (data acquired by the fish finder and data of the school of fish or the sea bottom) based on the reflection wave. Moreover, the fish finder 14 of this embodiment has a function to determine a state of the sea bottom (bottom sediment type) based on the acquired fish finding data. Specifically, the analyzer can determine which kind the sea bottom falls in with higher possibility, among rocks, gravel (stones), sand, and mud, by analyzing the received reflection wave. The fish finding data and the determined bottom sediment type are outputted to the touch panel device 11. Then, the controller 25 of the touch panel device 11 creates a third sensor image 33 based on the received data (see
The heading sensor 15 is configured to detect a heading of the ship (a direction to which a bow of the ship is heading) by a terrestrial reference absolute position. Generally, a ship travels forward, toward its bow direction. Therefore, it can be said that the heading sensor 15 detects an azimuth of the forward direction of the hull of the ship. For example, a magnetic azimuth sensor or a GPS compass may be used as the heading sensor 15.
The autopilot device 16 is a device for automatically controlling a rudder so that the ship travels along the set navigation route. Specifically, the autopilot device 16 obtains how much the bow of the ship is to be changed based on the heading acquired from the heading sensor 15 and the navigation route acquired from the touch panel device 11. Then, the autopilot device 16 matches the course of the ship with the navigation route by changing an angle of the rudder according to the obtained value.
The ship instrument network system 1 of this embodiment is configured as described above. Note that, the ship instruments constituting the ship instrument network system 1 are arbitrary, and a configuration in which ship instrument(s) other than those described above are connected, or a configuration in which a plurality of similar types of ship instruments are connected may be adopted. Moreover, a configuration in which the processing of the data acquired by the ship instruments is performed by the ship instrument concerned may be adopted, or a configuration in which the processing of the data acquired by the ship instruments is performed by the controller 25 of the touch panel device 11 may be adopted.
Next, a method of changing the position of the waypoint with the touch operation is described.
First, a “grab operation” and a “drop operation” which are touch gestures used to, for example, change the position of the waypoint are described with reference to
Next, with reference to
Moreover, as a specific example of the area creating method, for example, as illustrated in
Note that, the specifying method of the symbol described above is an example, and various kinds of other methods can be given. For example, instead of specifying only one symbol to be the operation target, as illustrated in
Next, “states” to be set in this embodiment are described with reference to
Next, the operation that the operator performs to change the position of the waypoint by using the grab operation and the drop operation, and the processing performed by the controller according to the operation of the operator are described with reference to
When performing the grab operation in the normal state, the state is shifted to the grabbing state, and cut processing is performed on the target symbol of the grab operation. Therefore, as illustrated in
Then, the operator determines a position of a changed destination of the symbol S12, and performs the drop operation so as to spread the fingers centering on the position (see
As described above, in this embodiment, the selection of the symbol and the cut processing can be performed in one action, and the specification of the position to be pasted to and the paste processing can also be performed in one action. Therefore, compared to the method of Patent Document 1, simple operation is achieved.
Next, the pinpoint zooming is described with reference to
Generally, when the operator desires to obtain detailed information of the vicinity of a certain symbol, the operator performs the pinch-out operation or the like to enlarge the entire nautical chart. Note that, there is a case where it is required to scroll to the vicinity of the relevant symbol as needed. Although the detailed information can be obtained by enlarging the entire nautical chart, overall information becomes uneasy to obtain. Moreover, the operator needs to change the nautical chart back to a suitable scale by performing the pinch-in operation or the like after acquiring the required information.
In this embodiment, in order to solve these problems, the touch panel device is configured to be able to perform the pinpoint zooming. When the state is in the normal state, the operator performs the drop operation on the symbol of which detailed information is desired to obtain (see
Note that, the drop operation performed with three fingers to perform the pinpoint zooming is in common with the pinch-out operation performed with two fingers, in view of bringing a plurality of fingers close to each other in the state of touching the display screen (note that, the grab operation and the pinch-in operation also similarly resemble each other). Therefore, by assigning the zooming function of enlarging the entire nautical chart to the pinch-out operation, and assigning the pinpoint zooming function described above to the drop operation, an operation system which is instinctive and easy to understand for the operator is achieved.
As described above, the touch panel device 11 includes the display unit 21, the detector 24, and the controller 25. The display unit 21 displays, on the display screen, the nautical chart and the symbol indicating the waypoint arranged on the nautical chart. The detector 24 detects touches at three or more positions on the display screen and their touched positions. The controller 25 creates the area based on the three or more touched positions detected by the detector 24, specifies the symbol located within the created area, and performs the cut processing thereon.
Thus, the cut processing of the symbol can be performed by the operation which is simple and with which mistakes hardly occur.
Although the preferred embodiment of the present invention is described above, the above configuration may be modified as follows, for example.
In the above embodiment, the configuration in which the area is created based at the three or more touched positions is adopted; however, a configuration in which the area is created based on two or less touched positions, or four or more touched positions may be adopted. Hereinafter, specific examples thereof are described. For example, when the number of touched positions is one, the circle centering on the touched position (a radius thereof is set in advance) can be the area. Further, when the number of touched positions is two, the circle having the diameter as the line coupling the two touched positions can be the area. Further, when the number of touched positions is four, the graphic formed by coupling all the touched positions can be the area.
In the above embodiment, the configuration in which the cut processing or the pinpoint zooming processing is performed on the specified symbol is adopted; however, the processing performed on the specified symbol is arbitrary, and a configuration in which the copy processing or deletion is performed may be adopted, for example. Moreover, a configuration in which the processing to be performed is set in advance, or the operator selects the processing after the symbol is specified may be adopted.
In the above embodiment, the configuration in which the grab operation and the drop operation are performed by using the touches at three or more positions; however, a configuration in which the grab operation and the drop operation are performed based on two or less touched positions, or four or more touched positions may be adopted.
The grab operation and the drop operation are not essential, and a configuration in which the area is created based on the touched position(s) and only the specifying of the symbol is performed may be adopted. For example, a configuration may be adopted in which tap operation (operation in which finger(s) touch for only a moment) with three fingers is performed to specify the symbol based on the tapped positions, and the operation on the specified symbol is performed by, for example, a physical key.
In this embodiment, the embodiment in which the GPS is used as one example of the GNSS is described; however, needless to say that the configuration may be such that other kind of GNSS is used.
The touch panel device 11 of this embodiments is a general display device which receives information from a plurality of sensors and displays it; however, the present invention may also be applied to a display device which displays mainly one kind of information (e.g., nautical chart information). Moreover, the present invention may also be applied to, for example, a plotter apparatus which can display symbols on a nautical chart, a radar apparatus which can display symbols on a radar image.
The touch panel device may be, other than the display device installed in ships, a display device (e.g., a navigation device) installed in movable bodies such as automobiles and aircrafts, a tablet PC, a smart phone, a handheld terminal, etc. For example, as a navigation device, similarly to the above embodiment, the present invention may be utilized, for example, to move a destination, a stopover point, and a predetermined point. Moreover, as a tablet PC and the like, the present invention may be utilized, for example, to select, move, and cut-process an icon for activating an application.
