BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Detection system)
FIG. 1 is a schematic diagram of a detection system according to an embodiment of the present invention. FIG. 1A shows a television 100 and an infrared remote controller (remote controller) 200 for the television, and FIG. 1 shows the internal structure. The following description is based on the assumption that the main power supply of the television 100 is turned on.
[0011]
First, a procedure for displaying a content, for example, a television program on the television display unit 110 using the infrared remote controller 200 will be described. The user operates a power button or a channel designation button of the infrared remote controller 200 to designate a program to be watched. Wireless information from the infrared remote controller 200 is input to the remote controller receiving unit 120 and is decoded by the control unit 140. Then, the control unit 140 sends channel information according to the decoded information or information instructing to raise or lower the volume to the tuner 160. The tuner 160 displays a television program received by the antenna 150 or the like on the display unit 110 according to the channel information. Through this series of procedures, the user can view the desired television program.
[0012]
If a timer (not shown) is provided in the control unit 140, such an operation history of the user of the infrared remote controller 200 can be stored in a storage unit 170 such as an HDD (hard disk drive) or a flash memory. The operation status of the user can be detected.
[0013]
In this way, the operation history of the user stored in the storage unit 170 can be sent to an acquaintance of the user connected to the Internet 300 via the control unit 140 and the communication interface 180. For example, even if the user is an elderly person, by using the present system, it is possible to notify the user's living situation by sending the user's operation history to a family or the like who lives apart from the user. In addition, since the user's living situation that is known by the present system is the operation history of the infrared remote control of the television used every day, for example, a photoelectric sensor provided at the entrance of the living room or a pressure-sensitive sensor provided on the bed of the bedroom. A conventional user monitoring system that eliminates the need for sensors that need to be installed in the room, and simply places a household appliance that is frequently used every day in the room where the user lives, and a TV that is designed to save power. Unlike this, the installation of the sensor is easy. Furthermore, even if the infrared remote controller is used many times, it is not embarrassing, and there is no discomfort of being monitored like a camera, thereby respecting the user's privacy.
[0014]
(When using an ultrasonic sensor)
Next, a description will be given of a system for detecting a user's movement when a distance sensor 130 such as a distance sensor ultrasonic sensor is provided in advance on the television 100 as shown in FIG. The ultrasonic sensor 130 can be used as an ultrasonic distance meter. As a measuring method, a method is used in which an ultrasonic pulse signal is applied to an object to be measured (in the case of the present embodiment, a user), and a distance is calculated from a time until a signal rebounded from the object to be measured is received.
[0015]
If this ultrasonic sensor 130 is used, the control unit 140 can control the ultrasonic sensor 130, apply an ultrasonic pulse to the user at predetermined time intervals, and store the operation history of the user in the storage unit 170. , The operation status of the user can be detected. In addition, if the user does not move after the elapse of the predetermined time, the control unit 140 determines that the user is faint or has fallen, even if the television is on, and determines the safety of the user on the Internet 300. You can contact the user's acquaintance via.
[0016]
Further, when the ultrasonic sensor 130 is compatible with IPv6 (Internet Protocol Version 6), an acquaintance of a user can control the ultrasonic sensor 130 via the Internet 300 by a control unit of a monitoring television described below, By applying an ultrasonic pulse into the room, it is possible to confirm in real time where the user is, and if it does not move even after a long time, it can be inferred that the user has fallen. In addition, there is no discomfort of being monitored like a camera, and respect for the user's privacy is maintained.
[0017]
(Monitoring system)
FIG. 2 is a schematic diagram of a monitoring system using the detection system (detection television 100) described with reference to FIG. 1. For simplification of description, only the display unit is shown as the configuration of the television. The detection television 100, the detection & monitoring television 400 capable of both detection and monitoring, and the monitoring television 500 are connected via the Internet 300, and an icon of the detection television is displayed on the screen of the monitoring television. For example, the detection and monitoring television 400 is provided with an icon of the detection dedicated television 100, and the monitoring dedicated TV 500 is provided with icons of the detection dedicated television 100 and the detection and monitoring television 400. In the figure, for the sake of simplicity, the icon of the detection-dedicated television 100 and the icon of the detection and monitoring television 400 are simply indicated as “100” and “400”, respectively.
[0018]
(How to obtain detection information)
FIG. 3 is a flowchart for explaining a method by which the monitoring television obtains information detected by the detecting television. Here, a case will be described in which the monitoring television 500 of FIG. 2 obtains information detected by the detection television 100. The monitoring television transmits the ID and the password to the detection television via the Internet (S100). Regarding the transmission method, the transmission may be automatically performed by clicking an icon on the screen of the monitor-dedicated television, or may be set in advance so as to be transmitted periodically (for example, every hour). . The control unit of the detection-dedicated television determines whether or not the detected information can be sent based on the received ID and password, and then sends the detected information. Through this series of procedures, the receiving unit (not shown) of the monitoring television can receive the detection information (S110). By using such an ID and a password, the detection television can provide detection information only to a specific monitoring television. The privacy of the user of the TV dedicated to detection can be protected.
[0019]
Next, a method of displaying the received information will be described. The control unit (not shown) of the monitoring television can select either text display or icon display of the received information (S120). When the text display is selected, the information received from the detection-dedicated television 100 is displayed as “100 → TV-ON; 08:02 TV-OFF; 10:30” as shown in FIG. It can be displayed (S130). When the text display is selected, the content of the short mail sent by the user of the television for detection can be displayed. For example, if "4 / 27-5 / 6: traveling" is displayed, even if the detected user does not use the television during that period, there is no need to worry about unnecessary use.
[0020]
On the other hand, when the icon display is selected (No in S120), it is first confirmed whether or not the power of the television is on based on the reception information (S140). Subsequently, it is confirmed whether or not there is a remote control access within a predetermined time (for example, one hour) (S150). If there is an access, it is determined that the user is fine, and an icon (for example, a laughter mark) indicating 100% is displayed (S160). If there is no access, it is further confirmed whether or not the ultrasonic sensor has sensed the user's movement (for example, going in and out) within a predetermined time (for example, one hour) (S170). If it can be sensed, it is determined that it is almost fine, and an icon (for example, a smiley mark) indicating 80% is displayed (S180). If it cannot be sensed, it is determined that the user is uneasy, and an icon (for example, a crying face mark) indicating anxiety is displayed (S190). The icon indicating this anxiety may be displayed even when the television is not turned on (No in S140). By using such an icon, the person monitoring can intuitively judge the safety of the monitored side.
[0021]
The above-described text display or icon display may be displayed on a so-called blue screen of the monitoring-dedicated television (a state in which the main channel of the television is turned on and an appropriate channel is not set). With this display, monitoring can be performed for 24 hours even if the monitoring side does not watch the television program.
[0022]
Since the above-described embodiments are preferred specific examples of the present invention, various technically preferable limitations are given. However, any combination and change may be made as appropriate without departing from the spirit of the present invention. It goes without saying that it can be done. For example, an infrared sensor may be used instead of the ultrasonic sensor 130, and the television 100 is merely a display device, and the control unit 140, the storage unit 170, and the communication interface 180 are provided in a home server. Is also good. Further, the infrared remote controller 200 may support IrDA (Infrared Data Association) or Bluetooth in consideration of data transmission / reception.
