Further, the image information loaded from the personal computer includes not only screen information, but also teaching material data stored in the personal computer, teaching material data read out from an external storage medium, and the like. The image information or the voice information is loaded into an instructor's terminal which controls the instructor's device and into a student's terminal which controls the student's device, and is transmitted from the respective terminals to the other terminals, via the transmission means. The student's device comprises: a personal computer as a lesson device an image taking means for taking a student's image and an image of a keyboard a voice input means for inputting student's a voice a transmitting means for multiplexing image information and voice information and for transmitting multiplexed information to the instructor's device, wherein the image information is either the one loaded from the personal computer or the one taken by the image taking means, and the voice information is the one which is input by the voice input means a display means for displaying image information sent from the instructor's device and a voice output means for outputting voice information sent from the instructor's device. The instructor's device comprises: a personal computer as a lesson device an image taking means for taking an instructor's image and an image of a keyboard a voice input means for inputting instructor's voice a mixer switcher means for mixing or switching between image information loaded from the personal computer and image information taken by the image taking means, where either the mixing or the switching is conducted as required a transmitting means for multiplexing image information and voice information and for transmitting multiplexed information to the student's device, wherein the image information is the one which is mixed or switched as required, by the mixer switcher means, and the voice information is the one which is input from the voice input means a display means for displaying image information sent from the student's device and a voice output means for outputting voice information sent from the student's device.

SUMMARY OF THE INVENTIONĪccording to this invention, a personal computer lesson system using videophones comprises an instructor's device for teaching how to operate a personal computer, and a student's device for learning how to operate a personal computer, where both devices being bidirectionally connected to each other via a communication line of various types. In this system, even if a personal computer goes down during a lesson, the videophone facility allows the lesson to go on. An object of this invention is therefore to provide a personal computer lesson system using videophones, wherein the connection of personal computers is separated from the communication facility of videophones. This invention is made to solve these problems. In this case, tasks achieved and the time spent in the previous lesson are wasted.

Another drawback is that, when a PC goes down, the only option is to reboot the PC, reconnect with the instructor's PC, and resume a lesson all over again. Once this happens, it is impossible to communicate with the instructor and to continue the PC lesson. One drawback is that, if a personal computer (PC) goes down (i.e., operation failure) during the operation or the like, a telephone line is disconnected. Nevertheless, this system has some drawbacks. In such conventional systems, an instructor's personal computer and a student's personal computer are connected via a standard telephone line, and share each other's screen image on their PC screens. BACKGROUND ARTĪs a method for teaching how to operate a personal computer, online personal computer lesson systems using videophones have been proposed. This invention relates to a personal computer (PC) lesson system using videophones.
