Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a home learning system that enables home learning using a demonstration robot.

``Conventional technology'' Audiovisual education systems that introduce video media into educational settings have already achieved numerous results across the country, and in addition to school education, home learning systems using communication satellites are becoming a reality. The expansion of educational media is astounding. A home learning system that uses video media can always provide homogeneous education to an unspecified number of learners, and it is possible to provide uniform education to an unspecified number of learners at all times. Recording allows you to take advantage of benefits such as being able to receive the same education over and over again at any time. On the other hand, in preparation for the coming aging society, various attempts have been made to promote lifelong learning, such as a correspondence education system where students complete a prescribed curriculum at home and a home learning system using public broadcasting, which allows individuals to participate. There is a lot of interest in the nature of learning systems.

[Problems to be solved by the invention] Conventional home-based learning systems are good for learning through paper or video, but for subjects that require students to actually move their bodies while watching the instructor's movements, such as in practical instruction. The problem with this is that the learning effect is poor because learners cannot see the practical exercises that serve as models, and because they assemble information learned from two-dimensional visual information sources in their heads, it is difficult to convey important movements. was there. For this reason, subjects such as flower arrangement, tea ceremony, and Japanese dance, which have traditionally been taught one-on-one by instructors, are
There were also limits to the ability to study at home when it came to high-motion sports such as skiing, tennis, and golf, as well as exercise such as aerobics, which were often excluded from the scope of home-based learning.

[Means for Solving the Problems] The present invention solves the above problems, and includes a receiving terminal that receives demonstration information sent from an information center via a telephone line, and a receiving terminal that receives demonstration information sent from an information center via a telephone line. The present invention is characterized by comprising a demonstration robot that is driven based on demonstration information and performs a model performance corresponding to the demonstration information.

[Operation] This invention receives demonstration information sent from an information center via a telephone line, drives the demonstration robot based on the received demonstration information, and causes the demonstration robot to actually perform a model performance. Students will be able to learn practical skills while watching model performances up close.

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is a system configuration diagram showing an embodiment of the home learning system of the present invention, FIG. 2 is a schematic configuration diagram of the receiving terminal shown in FIG. 1, and FIG. FIG. 2 is a diagram showing a data structure of demonstration information.

The home learning system 1 shown in FIG. 1 includes a receiving terminal 4 that receives demonstration information sent from an information center 3 via a telephone line 2, and is driven based on the demonstration information received by the receiving terminal 4. Demonstration robot 5 that actually performs a model performance
constitutes the main part of the system. In the case of the embodiment, the central information center 3 and the receiving terminal 4 in a general household are capable of high-level information communication necessary for controlling the demonstration robot S.
It is connected via the 15DN network. 15DN provides various voice and non-voice communication services on the same network, and is translated as integrated service digital communication network. The feature of this l5DN interface is that in addition to the B channel used for circuit switching and packet switching information transmission, there is a D channel used for controlling multiple information channels that are multiplexed of the B channel. That's true. In other words, by using the common line signal function of this D channel, the control information necessary to set up the communication line is transmitted to the exchange, and the connection is performed such as the address of the other party's terminal, communication settings, notification of cancellation, etc. By providing services and further using the D channel as a signal channel, communication between users and three-way conferences become possible.

When establishing a line connection between the information center 3 and a general home or office using l5DN, an l5DN line interface 6 is required in the receiving terminal 4, as shown in FIG. l5
The DN line interface 6 is connected to a CPU 7 that centrally controls the operation of the entire receiving terminal 4 via a system bus 8, and the system bus 8 includes a ROM 9 and a ROM 9 storing programs necessary for controlling the operation of the CPU 7. , or RAM l01 for storing calculation data etc. of the CPU 7.
A display section 11 that visually displays messages and a control section 12 that receives control commands for controlling the demonstration robot 5
etc. are connected to the branch. The control unit 12 includes a drive unit 1 for electrically or mechanically driving the demonstration robot 5.
3 is connected to the drive unit 13, which receives a movement command from the control unit 12 and causes the demonstration robot 5 to perform a model performance.

As shown in Figure 3, the demonstration data sent from the information center 3 is initialized with data indicating the total data length at the beginning, and a blank data field prepared for expansion reserve. Data indicating the data length of the data follows. Then, initial setting data for instructing the initial posture of the demonstration robot 5 follows, followed by data indicating the sending timing of control data necessary for actually moving the demonstration robot 5. The CPU 7 has a built-in counter (not shown) that is reset when initial setting data is received, and when the counted value of this counter matches the data indicating the above-mentioned sending timing, it sends a message to the control unit 12. By sending control data, the timing of each frame of movement of the demonstration robot 5 is defined.

In addition, the pig that indicates the timing of sending control data is
Data indicating the length of the control data follows, and finally the control data is sent. The control data includes part data indicating the part of the demonstration robot 5 that is to be moved, data indicating the presence or absence of movement of each part, data indicating the direction of movement, data indicating the speed of movement, etc. Included.

That is, a series of data from the control data transmission timing data to the control data is divided into blocks based on basic movements of the demonstration robot 5, and a plurality of such blocks are collected to transmit one demonstration information.

Here, when learning Japanese dance with the demonstration robot 5 as a teacher, the telephone line 2 is first connected to the information center 3, and Japanese dance is selected from the lesson menu displayed on the display section 11. However, the demonstration robot 5 must be set in a location that provides a certain amount of movement space for performance guidance. Then, when the information center 3 or 6 Japanese dance practice menu is sent, the user specifies the menu that is the practice topic for that day. Then, the information center 3 starts transmitting the dance lesson with the specified content, and the demonstration robot 5
starts dancing in response to control commands. Therefore, the user can practice while seeing the movements of the demonstration robot 5, and can speed up his/her progress by gaining advanced practice that would be difficult to master from a two-dimensional image.

As described above, according to the home learning system 1, the demonstration information sent from the information center 3 via the telephone line 2 is received, and the demonstration robot 5 is controlled based on the received demonstration information.
By driving the demonstration robot 5, practical learning can be performed while watching the performance of the demonstration robot 5, so three-dimensional visual information that is difficult to convey using conventional display devices that display video information on a flat surface can be transmitted. , can be presented in front of the home learners using the demonstration robot 5, which allows the teacher to stand on the podium and provide learning guidance that is almost equivalent to or more closely provided in the classroom, and can also be used in place of the instructor. The demonstration robot 5 can respond to any learning content according to the demonstration content sent from the information center 3, so a wide variety of learning can be done while at home or in the office. By using the information communication system, the demonstration robot 5 can perform complex and detailed demonstrations, making it possible to conduct home learning with extremely high educational effects.

In the above embodiment, Japanese dance performed by the demonstration robot 5 was taken as an example, but the demonstration program is not limited to Japanese dance, but may include practical skills such as flower arrangement, tea ceremony, or pottery, as well as aerobics, tennis, ski golf, etc. It may be a sport or even a special skill such as sign language.

Furthermore, the information center 3 and the receiving terminal 4 can be connected through a general public line, and it does not matter whether the connection is wired or wireless.

``Effects of the Invention'' As explained above, this invention receives demonstration information sent from an information center via a telephone line, drives a demonstration robot based on the received demonstration information, and performs a model performance. The structure is designed so that students can learn practical skills while watching the model performance of a demonstration robot up close.
Three-dimensional visual information, which is difficult to convey using conventional display devices that display video information in a two-dimensional manner, can be presented in front of the eyes of home learners using a demonstration robot. It is possible to provide close learning guidance that is almost equivalent to or more closely taught than classes held while standing.
In addition, the demonstration robot that acts as a teacher can respond to any learning content depending on the demonstration content sent from the information center, so a wide variety of learning can be done while at home or in the office. By using such an advanced information and communication system, demonstration robots can perform complex and precise demonstrations, making it possible to conduct home-based learning with extremely high educational effects.
