[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a terminal device according to an embodiment to which the present invention is applied will be described with reference to the drawings. First, FIG. 1 shows two aspects of the appearance of the terminal device 1 according to the present embodiment. The terminal device 1 in the mode of FIG. 1A is used, for example, placed on a desk, or embedded in a wall or a pillar and used. The terminal device 1 in the mode of FIG. 1B is installed and used in, for example, a convenience store or a station square.
[0013]
The terminal device 1 is provided with a housing 10 in any of the modes shown in FIG. 1, and an input / output unit 11 and a motion sensor 12 provided below the input / output unit 11 are provided from the housing 10. Is exposed to the outside. The input / output unit 11 and the motion sensor 12 face in the same direction. This terminal device 1 is preferably used, for example, as an information processing terminal for business use (a so-called KIOSK terminal or the like).
[0014]
The input / output unit 11 can be realized, for example, by including a touch panel as an input device and an LCD (Liquid Crystal Display) as a display device. The motion sensor 12 senses in front of the input / output unit 11, that is, in front of the terminal device 1, and outputs information for determining whether or not there is a person to a determination unit 23 described below. The motion sensor 12 may further have a function as a color sensor capable of determining a color. That is, the motion sensor 12 may acquire color information for determining the color of a person in front of the terminal device 1 (for example, the color of clothes of a person in front of the terminal device 1). This color information is represented by a value (for example, 0 to 255) within a predetermined range for each of R (red), G (green), and B (blue). The color information acquired here is output to the determination unit 23 described later. Note that the color sensor may be configured separately from the motion sensor.
[0015]
FIG. 2 is a diagram illustrating an example of the configuration of the terminal device 1. The terminal device 1 includes the input / output unit 11 and the motion sensor 12 described above, and the information processing unit 20. The information processing unit 20 is configured by, for example, a general-purpose computer system, and individual components or functions in the information processing unit 20 described below are realized, for example, by executing a computer program. For example, the content in the content storage unit 25 described later is described in HTML (Hyper Text Markup Language), and the input / output control unit 22 and the determination unit 23 can be realized by a Web browser and a plug-in module.
[0016]
The information processing unit 20 includes an authentication processing unit 21 that authenticates a user of the terminal device, an input / output control unit 22 that controls the input / output unit 11, and a terminal device 1 based on an output from the motion sensor 12. If there is a person in front, and if there is a person, a determination unit 23 that performs color determination, which will be described later, a user database 24 that stores information on registered users, and various contents to be displayed on the input / output unit 11 , A storage unit 26 for storing color information, and a timer 27.
[0017]
The authentication processing unit 21 authenticates a user who uses the terminal device 1. The authentication processing unit 21 inputs a user ID and a password from the input / output unit 11, for example, and performs authentication based on the information and the user information stored in the user database 24. The user database 24 may be connected to the terminal device 1 via a network, for example, and may include an accessible server.
[0018]
The input / output control unit 22 controls the input / output unit 11. For example, the input / output control unit 22 selects the content stored in the content storage unit 25 according to the input received by the input / output unit 11 and causes the input / output unit 11 to display the content. For example, when a menu screen is displayed on the input / output unit 11, the input / output control unit 22 stores information on a display screen of detailed information on the selected menu in a content when receiving a menu selection input from the user. The screen is obtained by acquiring from the unit 25. In addition, the input / output control unit 22 may display a specific page for the authenticated user for the user authenticated by the authentication processing unit 21.
[0019]
The processing of the determination unit 23 will be described with reference to the flowcharts of FIGS. First, the first processing procedure shown in FIG. 3 will be described.
[0020]
When the user uses the terminal device 1, for example, when a screen other than the initial screen is displayed on the input / output unit 11, the determination unit 23 initializes the counter of the timer 27 and starts counting (S11). Here, the screen displayed on the input / output unit 11 may be a screen provided only to the authenticated user. Then, the motion sensor 12 and the determination unit 23 check whether there is a person in front of the input / output unit 11 (S12). Here, when a person is detected (S12: Yes), the process returns to step S11, and the timer 27 is reset. When a person is not detected (S12: No), the determination unit 23 inquires of the timer 27 about the elapsed time, and determines whether a predetermined elapsed time has elapsed (S13). This predetermined elapsed time is for determining whether or not to switch the screen, and is hereinafter referred to as a switching time. The switching time can be, for example, about 3 seconds. If the switching time has not elapsed (S13: No), the process returns to step S12. When the switching time has elapsed (S13: Yes), that is, when the time during which the motion sensor 12 does not detect a person exceeds the switching time, the process exits the loop of steps S11 to S13, and in step S14, the motion sensor 12 and the determination are determined. It is determined whether the unit 23 has detected a person (S14).
[0021]
Here, when a person is detected (S14: Yes), the input / output control unit 22 causes the input / output unit 11 to display a menu screen, and switches from the screen being displayed (S15). When a person is detected in step S14, there is a high possibility that the person is not the same person as the user who displayed the screen displayed at that time. That is, it is highly probable that the user who has used the terminal device 1 has left and a new user has come to the terminal device 1. Therefore, by switching to the menu screen, this user can immediately use the terminal device 1. You can get started.
[0022]
If no person is detected in step S14 (S14: No), the determination unit 23 inquires of the timer 27 about the elapsed time, and determines whether a predetermined elapsed time has passed (S16). This predetermined elapsed time is for determining a timeout, and is hereinafter referred to as a timeout time. If the timeout time has not elapsed (S16: No), the process returns to step S14. If the timeout time has elapsed (S16: Yes), the input / output control unit 22 causes the input / output unit 11 to display an advertisement screen (S17). Alternatively, a predetermined initial screen may be displayed instead of the advertisement screen. The initial screen and the menu screen may be the same screen or different screens.
[0023]
After switching to the advertisement screen, the determination whether the motion sensor 12 and the determination unit 23 have detected a person is continued (S18). When a person is detected in step S18, the input / output control unit 22 performs a screen switching process in step S15.
[0024]
Next, the second processing procedure shown in FIG. 4 will be described. In this processing procedure, processing using color information is further performed.
[0025]
When the user uses the terminal device 1, for example, when a screen that is not the initial screen (including a screen for an authenticated user) is displayed on the input / output unit 22, the determination unit 23 initializes the counter of the timer 27. Then, counting is started (S21). At this time, the color information indicating the color of the person detected immediately before by the determination unit 23 is stored in the storage unit 26 (S22). Here, the color information includes, for example, a value measured by the motion sensor for each of RGB. Then, the motion sensor 12 and the determination unit 23 check whether there is a person in front of the input / output unit 11 (S23). Here, when a person is detected (S23: Yes), the process returns to step S21. If no person is detected (S23: No), the determination unit 23 inquires of the timer 27 about the elapsed time and determines whether the switching time has passed (S24). If the switching time has not elapsed (S24: No), the process returns to step S23. When the switching time has elapsed (S24: Yes), that is, when the state in which the motion sensor does not detect a person has continued for the switching time or more, the process proceeds to step S25, and the motion sensor 12 and the determination unit 23 have detected a person. It is determined whether or not it is continued (S25).
[0026]
Here, when a person is detected (S25: Yes), the determination unit 23 performs color determination by comparing the color information detected by the motion sensor 12 with the color information stored in the storage unit 26 ( S26). That is, the determination unit 23 determines whether the color of the person detected by the motion sensor 12 is the same as the color indicated by the color information stored in the storage unit 26. Here, it is determined whether or not the colors are the same, for example, when the respective values of RGB completely match, or even when some or all of the RGB values are different, the difference is determined by a predetermined value. Are within the range, it is assumed that the colors are the same.
[0027]
As a result, if the detected color of the person is not the same as the color indicated by the color information stored in the storage unit 26 (S26: No), the input / output control unit 22 displays the color on the input / output unit 11. The middle screen is switched to the menu screen (S27). On the other hand, when the color of the person detected here and the color indicated by the color information stored in the storage unit 26 are the same color (S26: Yes), the screen switching in step S27 is not performed.
[0028]
In the case of processing using color information, after the switching time has elapsed, a person is detected in step S25, and then the color of the detected person is compared with the color of the person who displayed the screen being displayed. Then, whether or not they are the same person is determined in two stages. As a result, the accuracy of determining whether or not the persons are the same is improved.
[0029]
If no person is detected in step S25 (S25: No), the determination unit 23 inquires of the timer 27 about the elapsed time, and determines whether the timeout time has elapsed (S28). If the timeout time has not elapsed (S28: No), the process returns to step S25. If the timeout period has elapsed (S28: Yes), the input / output control unit 22 causes the input / output unit 11 to display an initial screen (S29). Alternatively, an advertisement screen may be displayed instead of the initial screen.
[0030]
Next, a second embodiment will be described. The description of the present embodiment will focus on the differences from the first embodiment, and the same reference numerals will be given to the same functions or configurations as those of the first embodiment, and description thereof may be omitted.
[0031]
FIG. 5 shows the appearance of the terminal device 5 according to the second embodiment. In the terminal device 5, the input / output unit 11 and the plurality of motion sensors 12 are exposed from the housing 10. In the example shown in FIG. 5, the terminal device 5 has two motion sensors 12. Each of the motion sensors 12a and 12b is installed facing the same direction as the input / output unit 11.
[0032]
The motion sensors 12a and 12b are arranged such that when installed in a state where the terminal device 5 is normally used, the heights from the respective floor surfaces are different from each other. For example, the motion sensor 12a is arranged above the input / output unit 11, and the motion sensor 12b is arranged below the input / output unit 11. In the example of FIG. 5, the height of the motion sensor 12a from the floor is 1.5 m, and the height of the motion sensor 12b from the floor is 1 m. Thus, it is preferable that the difference in height between the motion sensor 12a and the motion sensor 12b is 0.5 m or more.
[0033]
FIG. 6 shows a functional configuration of the terminal device 5 according to the second embodiment. The motion sensors 12a and 12b independently detect a person. Therefore, there are four patterns shown in FIG. 7 for the detection and non-detection of a person by the motion sensors 12a and 12b. That is, (1) both motion sensors 12a and 12b detect, (2) both motion sensors 12a and 12b do not detect, (3) motion sensor 12a does not detect, motion sensor 12b detects, (4) motion sensor 12a indicates detection, and the motion sensor 12b does not detect.
First, in the case of (2), the determination unit 29 determines that there is no person in front of the terminal device 5. In the case of (1), the determination unit 29 determines that a person having a certain height or more stands in front of the terminal device 5. At this time, the input / output control unit 22 acquires the content for adults from the content storage unit 25 and causes the input / output unit 11 to display the content.
In the case of (3), the determination unit 29 determines that a person having a certain height or less stands in front of the terminal device 5. At this time, the input / output control unit 22 acquires the content for children from the content storage unit 25 and causes the input / output unit 11 to display the content.
In the case of (4), the determination unit 29 determines that there is no person in front of the terminal device 5 (false detection).
[0034]
The terminal device 5 according to the present embodiment also performs processing according to the flowcharts shown in FIGS. At this time, for example, taking FIG. 3 as an example, the determination of whether or not a person has been detected in steps S12, S14, and S18 follows the criteria described above. That is, in the cases (1) and (3), it is determined that a person is present in front of the terminal device 5. Further, in step S15, in the case of (1) (when it is determined that a person of a certain height is in front of the terminal device 5), a menu screen for adults is displayed, and in the case of (2) (the height is When it is determined that a person below a certain level is in front of the terminal device 5), a menu screen for children may be displayed.
[0035]
In the case of FIG. 4, the same applies to steps S23 and S25 for detecting a person and step S27 for displaying a menu screen.
[0036]
