Description

Embodiments relate to terminal devices, display methods, and programs.

In recent years, automatic ticket gates are often installed at railway stations to control entry and exit. There is known a technique for managing entry and exit using a portable terminal device. More specifically, on the terminal device side, an image such as a two-dimensional code in which various information necessary for passing through the automatic ticket gate is encoded is displayed on the display screen of the terminal device, and is displayed on this display screen2. Use the dimension code etc. as a ticket. On the other hand, on the automatic ticket gate side, an image including a two-dimensional code displayed on the terminal device at the time of entry and exit of the user is captured by a camera, and information is read from the two-dimensional code by a reading unit to determine whether or not to pass.

Further, there is also known a technique of changing the position of the two-dimensional code on the screen based on the operation of the user when the two-dimensional code is displayed on the display screen.

JP-A-2010-129048

By the way, at the time of entry / exit, the user needs to point the display screen of the terminal device toward the camera of the automatic ticket gate, in other words, the display screen must be on the opposite side of the palm. At this time, it is assumed that the user may grab the display screen with his / her finger without noticing it, and the fingertip may overlap with the two-dimensional code. If the two-dimensional code is hidden at the user's fingertip and the two-dimensional code to be imaged is lost in this way, the code cannot be restored from the two-dimensional code read by the automatic ticket gate, and an error occurs. It ends up. If an error occurs in a situation where it should be possible to pass through without problems, the user will not be able to pass through the automatic ticket gate. This hinders smooth entry and exit.

An object to be solved by the present invention is to provide a terminal device, a display method, and a program capable of realizing smooth entry / exit without causing an unnecessary error when a user enters / exits an automatic ticket gate. With the goal.

The terminal device according to one embodiment detects that the touch panel and the user's finger placed at a detectable position on the touch panel are at a position overlapping with the display of the display object displayed on the touch panel. If so, the control unit is provided to change the display position of the display object to a position that does not overlap with the position of the finger.

(First Embodiment)
FIG. 1 is a diagram showing an example of the appearance of the terminal device 100.
The terminal device 100 is a portable terminal device, for example, a smartphone. The terminal device 100 includes a touch panel 160, buttons, and the like on the front surface (the surface shown in the drawing). Further, a notification unit 190 is provided on the back surface (opposite side surface in the drawing). The touch panel 160 is a user interface, displays information to the user (user), and detects the position information of the user's finger placed on the touch panel or the protective sheet attached to the touch panel. Buttons and the like are used by the user to operate the terminal device 100. The notification unit 190 is a light emitting unit, and notifies the user (prompts a warning) by emitting light toward the back surface side of the terminal device 200.

FIG. 2 is a block diagram showing an example of the configuration of the terminal device 100.
The terminal device 100 includes a CPU 110, a ROM 120, a RAM 130, a communication unit 140, an interface 150, a touch panel 160, an HDD 170, a vibration unit 180, and a notification unit 190. Further, the CPU 110 is connected to each of the ROM 120, the RAM 130, the communication unit 140, the interface 150, the touch panel 160, the HDD 170, the vibration unit 180, and the notification unit 190 via a bus line.

The CPU 110 is a central processing unit, and executes a program stored in the HDD 170 by using the ROM 120, the RAM 130, and the like. The ROM 120 is a non-volatile memory, and stores a program or the like that is a base for operating the terminal device 100. The RAM 130 is, for example, a DRAM, and is used as a work area or the like when the CPU 110 executes a program.

The communication unit 140 communicates with the automatic ticket gate device 200 for making a payment regarding the ticket when the automatic ticket gate device 200, which will be described later, is brought close to a predetermined position. That is, the terminal device 200 has an IC card function, and the IC card function enables payment to be made via the automatic ticket gate device 200 and the communication unit 140. Interface 150 connects to the Internet, for example. The terminal device 200 can communicate with other devices connected to the Internet via the interface 150.

The touch panel 160 has a display unit 161 for displaying information to the user and a touch unit 162 for receiving an instruction from the user. In the present embodiment, the display unit 161 displays a display object. The display object includes a bar code and a two-dimensional code (for example, a QR code). Here, the display object means an information encrypted by using a predetermined encryption key, which is converted into an optically readable shape, pattern, color, or the like by a machine. The touch unit 162 is manufactured by a predetermined method such as a capacitance method or a resistance film method, and can detect the position information of the finger touched by the user.

The HDD 170 is a hard disk drive and stores various programs and data. In the present embodiment, the HDD 170 stores, for example, a display program 171 that displays a display object. The display program 171 is a program that displays a display object on the display unit 161 and changes the display position thereof, and the details will be described later with reference to FIG. Here, the content indicated by the display object relates to a ticket settled in advance in the present embodiment. The display object is issued when payment is made using a social network system using a predetermined application, and is stored in a predetermined position of the HDD 170 as data for generating a display object (illustrated). omit).

The vibrating unit 180 realizes a vibration function. For example, when the terminal device 200 receives an e-mail via the interface 150, or when a predetermined instruction is given from the CPU 110, the terminal device 200 is vibrated. The notification unit 190 is a light emitting unit that notifies the user (issues an alarm) as described above.

FIG. 3 is a diagram showing an example of the appearance of the automatic ticket gate device 200.
A plurality of automatic ticket gate devices 200 are installed at the entrance / exit of a station, for example, in parallel to regulate the entry / exit of users. The automatic ticket gate device 200 setstles a ticket corresponding to the boarding section used by the user with the user who enters and exits. The automatic ticket gate device 200 has a substantially rectangular shape and is erected with respect to the road surface together with the guide. A communication unit 240, a barcode reading unit 260, and a display unit 290 are provided on the upper surface of the automatic ticket gate device 200, and the first door opening / closing unit 281 and the second door opening / closing are provided on the surface opposite to the surface on which the guide is provided. A portion 282 is provided.

FIG. 4 is a block diagram showing an example of the configuration of the automatic ticket gate device 200.
The automatic ticket gate 200 includes a CPU 210, a ROM 220, a RAM 230, a communication unit 240, an interface 250, a reading unit 260, an HDD 270, a first door opening / closing unit 281, a second door opening / closing unit 282, and a display unit 290. Further, the CPU 210 is connected to the ROM 220, the RAM 230, the communication unit 240, the interface 250 reading unit 260, the HDD 270, the first door opening / closing unit 281, the second door opening / closing unit 282, and the display unit 290 via a bus line.

The CPU 210 is a central processing unit, and executes a program stored in the HDD 270 using the ROM 220, the RAM 230, and the like. The ROM 220 is a non-volatile memory, and stores a program or the like that is a base for operating the automatic ticket gate device 200. The RAM 230 is, for example, a DRAM, and is used as a work area or the like when the CPU 210 executes a program.

When the IC card or the terminal device 100 having the IC card function is brought closer to the user, the communication unit 240 communicates with the IC card or the terminal device 100 to make a payment regarding the ticket. The interface 250 is connected to, for example, an information processing device installed in a station. The automatic ticket gate device 200 can communicate with other devices via the interface 250.

The reading unit 260 includes a camera (not shown). In the present embodiment, the display object displayed on the touch panel 160 of the terminal device 100 is photographed by a predetermined operation of the user, and the information regarding the payment of the ticket is acquired from the photographed display object.

The HDD 270 is a hard disk drive and stores various programs and data. In this embodiment, the HDD 270 stores, for example, the payment program 271. The payment program 271 is a program for settling the ticket of a user who participates in the automatic ticket gate 200 based on the information related to the payment of the ticket acquired by the reading unit 260.

The first door opening / closing section 281 and the second door opening / closing section 282 restrict the entry and exit of the user, respectively. For example, if an error occurs when the CPU 110 makes a payment for a ticket using the bar code payment program 271, the door of the door opening / closing part on the opposite side of the user's entrance side is opened in the side direction to allow the user to participate. To regulate.

For example, the display unit 290 emits a green color when the payment of the ticket by the display object is completed normally, notifies the user that the payment is completed, and red when an error occurs in the payment. It emits light in the system to notify the user that an abnormality has occurred in the payment. The display unit 290 may also be provided with an audio output unit to output sound according to the payment status.

Next, the display process of the display object will be described. FIG. 5 is a flowchart showing an example of the display processing of the display object executed by the CPU 110.
The CPU 110 starts the display program (ST101). That is, the CPU 110 reads the display program 171 from the HDD 170 and executes it.

Next, the CPU 110 acquires the finger position information (ST102). The CPU 110 acquires the position information of the user's finger placed at a detectable position on the touch unit 162 based on the change in the capacitance of the touch unit 162 or the change in the resistance value. Then, the CPU 110 creates a display object (ST103). Specifically, the CPU 110 generates a display object based on the data of the display object stored in the predetermined position of the HDD 170. The display object thus generated is temporarily stored in, for example, the RAM 130.

Next, the CPU 110 determines (detects) whether or not the display object can be displayed at a fixed position (ST104). More specifically, when the CPU 110 displays the display object at a fixed position (for example, the center of the display unit 161), the CPU 110 of the user's finger placed at a position where the displayed display object can be detected by the touch unit 162. Determine if it overlaps the position.

When it is determined that the display can be performed at a fixed position (ST104: YES), the CPU 110 displays, for example, a display object stored in the RAM 130 at a fixed position (ST105). As a result, for example, the display object is displayed in the center of the display unit 161. On the other hand, when it is determined that the display cannot be displayed at a fixed position (ST104: NO), the CPU 110 shifts the display object from the position of the finger and displays it (ST106). As a result, the display object is displayed on the display unit 161 so as not to overlap the position of the user's finger. At this time, the display object may be displayed at the position farthest from the position where the finger is placed on the display unit 161 (touch panel 160).

After displaying the display object on the display unit 161 in this way, the CPU 110 acquires the finger position information again (ST107). Then, the CPU 110 determines whether or not the display object and the user's finger overlap (ST108). That is, it is determined again whether or not the display position on the display unit 161 of the display object and the position of the user's finger placed at the detectable position on the touch unit 162 overlap. When it is determined that the display object and the finger overlap (ST108: YES), the CPU 110 shifts the display object from the position where the finger is placed and displays the display object (ST109), as in step ST106 described above. If it is determined that the display object and the finger do not overlap (ST108: NO), the process proceeds to the next step ST110.

Next, the CPU 110 determines whether or not the display of the display object is completed (ST110). For example, the determination is made based on whether or not the end of display of the display object is instructed by the operation of a predetermined button of the user. If it is determined that the process is not completed (ST110: NO), the process returns to step ST107. By repeating the processes of steps ST107 to ST110 in this way, even if the position of the user's finger placed at a detectable position on the display unit 161 moves, the display object does not overlap with the finger. The display position of is moved on the display unit 161. If it is determined that the process is complete (ST110: YES), the CPU 110 terminates this process.

FIG. 6 shows the positional relationship between the display object 300 displayed at a fixed position on the touch panel 160 and the user's finger R placed on the touch panel 160 when the automatic ticket gate device 200 is made to read the display object 300. It is a figure.

When the bar code reading unit 260 of the automatic ticket gate device 200 is made to read the display object, the display unit 161 displaying the display object 300 is on the opposite side of the user's line of sight and cannot be seen. The user cannot grasp the positional relationship between the display position and the user's own finger R holding the touch panel 160. Therefore, as shown in FIG. 6, the display object 300 and the finger R may overlap with each other. In such a state, the barcode reading unit 260 cannot read the display object 300.

However, according to the terminal device 100 of the present embodiment, even if such a state occurs (ST108: YES), the display object 300 can be displayed by shifting from the position of the finger R (ST109). FIG. 7 is a diagram showing an example in which the display object 300 is displayed by shifting the position where the finger R in the state of FIG. 6 is placed. As a result, the reading unit 260 of the automatic ticket gate device 200 can read the display object 300. Note that FIG. 7 shows an example in which the display object 300 is displayed at the position farthest on the display unit 161 (touch panel 160) from the position where the finger R is placed, but at least the position where the finger R is placed is shown. The display position of the display object 300 may be changed so as not to overlap with.

The terminal device 100 described above determines whether or not the finger R of the user placed at the detectable position on the touch panel 160 overlaps with the position of the display object 300 displayed on the display unit 161. When it is determined that the position of the finger R overlaps with the position of the display object 300, the display position of the display object 300 displayed on the display unit 161 can be changed so as not to overlap with the position of the finger R. Therefore, it is possible to realize smooth entry / exit without causing an unnecessary error when the user enters / exits the automatic ticket gate device 200.

(Second Embodiment)
The second embodiment is different from the first embodiment in that even when the display object 300 and the user's finger R overlap, in a certain case, the display object 300 is not displaced from the finger R. That is the point. The same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

FIG. 8 is a flowchart showing an example of the processing of the present embodiment. This process is a process when NO is determined in step ST104 described above, that is, when it is determined that the display object 300 cannot be displayed at a fixed position.

If NO is determined in step ST104 described above, the CPU 110 calculates the loss rate of the display object 300 (ST201). Here, the loss rate is the ratio of the area hidden by the user's finger to the area of the display object 300 that cannot be read. For example, if the area of the display object 300 is 100 and the area hidden by the finger and unreadable is 20, the loss rate is 20%.

Next, the CPU 110 determines whether or not the loss rate is equal to or less than a predetermined ratio (ST202). When it is determined that the loss rate is equal to or less than a predetermined ratio (ST202: YES), the CPU 110 performs the process of step ST105, that is, the process of displaying the display object 300 at a fixed position. If it is determined that the loss rate is not equal to or less than a predetermined ratio (ST202: NO), the CPU 110 performs the process of step ST106, that is, the process of shifting the display object 300 from the position of the finger and displaying it.

Even if there is a part of the display object 300 that cannot be read because it is hidden by the finger R, the content can be restored as long as it is a certain percentage or less. Therefore, the terminal device 100 of the present embodiment does not need to move the display position of the display object 300 when it can be restored even if there is a portion that cannot be read by the finger R. There are multiple types of display objects, and the value of the loss rate that can restore the contents is also different. Therefore, it is desirable to determine the loss rate according to the type of display object used for ticket settlement.

(Third Embodiment)
The third embodiment is different from the first embodiment in that the user is warned when the overlap between the display object 300 and the finger R is not eliminated even if the display object 300 is moved from the finger R. That is the point. The same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

FIG. 9 is a flowchart showing an example of the processing of the present embodiment. This process is a process when NO is determined in step ST104 described above, that is, when it is determined that the display object 300 cannot be displayed at a fixed position.

If NO is determined in step ST104 described above, the CPU 110 determines whether or not the display object 300 can be displayed by shifting it (ST301). That is, it is determined whether or not the display object 300 can be moved so as not to overlap with the finger. When it is determined that the display object 300 can be displayed by shifting it (ST301: YES), the CPU 110 performs the process of step ST106 described above, that is, the process of shifting the display object 300 from the position of the finger R and displaying it. If it is determined that the display object 300 is not displayable by shifting it (ST301: NO), the CPU 110 performs the process of step ST106 after issuing a warning (ST302).

FIG. 10 is a diagram showing an example when two fingers R are placed at detectable positions on the touch panel 160. Since the touch panel 160 is gripped by the two fingers R in this way, the overlap cannot be eliminated even if the display object 300 is shifted. In such a situation, the terminal device 100 notifies the user. For example, the notification causes the notification unit 190 to emit light. At the same time as the light emission of the notification unit 190, the vibration unit 180 may be operated to vibrate the terminal device 100, or a voice output unit may be provided to output voice.

When the user enters and exits from the automatic ticket gate device 200 using the display object 300, the display unit 161 of the terminal device 100 is directed to the barcode reading unit 260 of the automatic ticket gate device 200, and therefore the user. The back side of the terminal device 100 faces the side. Therefore, the notification unit 190 provided on the back surface of the terminal device 100 is made to emit light to notify the user of an alarm (that the finger and the display object 300 overlap). As a result, the user can be warned that the display object 300 may be hidden by the user's finger R and the barcode reading unit 260 may not be able to read the display object 300.

(Fourth Embodiment)
The fourth embodiment is different from the first embodiment in that the size of the display object 300 is reduced when the overlap between the display object 300 and the finger R is not eliminated even if the display object 300 is displaced from the finger R. The point is that the processing to be performed is performed. The same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

FIG. 11 is a flowchart showing an example of the processing of the present embodiment. This process is a process when NO is determined in step ST104 described above, that is, when it is determined that the display object 300 cannot be displayed at a fixed position.

If NO is determined in step ST104 described above, the CPU 110 determines whether or not the display object 300 can be displayed by shifting it (ST401). That is, it is determined whether or not the display object 300 can be moved so as not to overlap the finger R. When it is determined that the display object 300 can be displayed by shifting it (ST401: YES), the process of step ST106 described above, that is, the process of shifting the display object 300 from the position where the finger R is placed and displaying the display object 300 is performed. ..

Further, when it is determined that the display object 300 is not displayable by shifting it (ST401: NO), the CPU 110 determines whether or not the size reduction condition is satisfied (ST402). Here, the size reduction condition will be described. FIG. 12 is a diagram for explaining the size reduction condition. In FIG. 12, the display area of the touch panel 160 is shown with the vertical axis Y and the horizontal axis X. The position X2 is the center position of the width of the display area, the position X1 is the position of the left end portion, and the position X3 is the position of the right end portion. In the present embodiment, the size reduction condition is a case where the user's finger R is simultaneously detected at the position X1 and the position X2 or the position X2 and the position X3 at the same position on the Y axis. FIG. 13 is a diagram showing an example of satisfying the size reduction condition. FIG. 13 shows a case where the user's finger R is detected at the position X2 and the position X3 at the same position on the Y axis. That is, the user's finger R is touching the touch panel 160 from the right side to the left side beyond the central portion, that is, half or more in the width direction.

When it is determined that the size reduction condition is satisfied (ST402: YES), the CPU 110 reduces the display size of the display object 300 (ST403). The size to be reduced can be arbitrarily set within a range in which the display object can be read by the reading unit 260. When the size reduction process is performed in this way, or when it is determined that the size reduction condition is not satisfied (ST402: NO), the process proceeds to step ST106. FIG. 14 is a diagram showing an example of the display object 300a in which the size reduction process is executed.

The terminal device 100 of the present embodiment can reduce the display object 300 and display it on the touch panel 160 as the display object 300a. Therefore, the terminal device 100 can change the position of the display object 300 displayed on the display unit 161 so as not to overlap with the position of the finger. Although FIGS. 13 and 14 show a case where the user has one finger R, a plurality of finger Rs may be placed on the touch panel 160 of the terminal device 200. In such a case, if the size of the display object 300 remains the same, there is a high possibility that there will be no moving position, and it is particularly effective to reduce the size of the display object 300.

In the second to fourth embodiments, the process when NO is determined in step ST104 is described, but when YES is determined in step ST108, that is, the display object 300 is displayed and then displayed. Similarly, when the object 300 and the finger R overlap, the processing described in the second to fourth embodiments can be applied. Since these processes have substantially the same description, the case where YES is determined in step ST108 is omitted in the second to fourth embodiments.

Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are also included in the scope of the invention described in the claims and the equivalent scope thereof.
