Description

systems used to guide students

The present invention relates to student instruction, and more particularly to a system for instruction. The system enables students to observe themselves against images of their instructors.

For example, when a student is learning to play golf or other sports, because he cannot watch himself while completing an action, whether he is a beginner or an advanced golfer, or a professional ball Hands, often unable to understand the essentials of movement. When a student is learning from a book, diagram, video or personal lesson, the student cannot see what he is doing in comparison to others. When a student attempts to perform a movement-related task, he cannot see himself in contrast to a predetermined action.

It is an object of the present invention to provide an improved system for student instruction which substantially overcomes or corrects the aforementioned disadvantages.

According to one aspect of the present invention, a system for student instruction is disclosed. The system includes: at least one display device for displaying a contrastive relationship between images of an instructor and a student; a mixer for receiving from a first source; at least one recorded image of an instructor; at least one a second source for providing at least one image of a student showing one or more students in real time as the student views the display device and attempts to imitate the instruction; and, the outputs of the first and second sources, They are connected with the mixer and simultaneously displayed on the display device as the guide image and the student image respectively.

Preferably, the first source includes an audio channel audible to the student so that the student can receive instruction while imitating the instructor.

Ideally the system will be embedded in an interactive learning system used to instruct students in: Industry, Medicine, Science, Art, Performance, Speech Therapy, Sports and all things related to learning styles Activities, as long as students can imitate or copy the actions of the instructor.

FIG. 4 is a schematic block diagram of a variation of the system shown in FIG. 3 .

A system 1 for instruction of a first preferred embodiment of the invention is described for exercise instruction in FIGS. 2 and 3 . A system 1 used by a student 2 includes a video monitor 3 with a split screen function. A video monitor 3 (eg, as shown in FIG. 2( a )) has a dividing line 4 on a screen 5 . The monitor 3 displays a first image 6 on one side of the screen 5 and a second image 7 on the other side of the screen 5 . The first image 6 is the image of the instructor 8 (previously recorded using the structure of Fig. 1(a)), and the second image is the image of the student 2 displayed in real time by the camera 21a.

Referring now to FIG. 1 ( a ), the video recorder 11 is used to record the first image 6 of the instructor 8 captured by the video camera 10 on the instruction tape 9 . In other examples, image 6 may be recorded on a disc or other device. The instructor 8 can complete the recording of the "lesson" by providing a script that is typed into a personal computer (PC) 12 . PC 12 provides signal 13 to audio indication sound synthesizer 14 , which in turn provides audiovisual signal 15 to video recorder 11 and loudspeaker 16 . The instructor 8 follows the instructions in the script provided by the voice synthesizer 14 . For example, instructions may also be provided by voice or live narration recorded on audio tape. The video camera 10 provides a video signal 17 to the video recorder 11 when the instructor 8 completes the task as directed. The video signal 17 is recorded synchronously with the audio signal 15 on the guide tape 9 for use. In Fig. 1(a), the instructor 8 faces the camera 10, but he can change his position according to other views described in Fig. 1(b) and Fig. 1(c) according to different instructions from the sound synthesizer 14, for example , side view or front view as required. In contrast to the configuration of Figure 2(a), more than one monitor 3 can be used at these positions. The corresponding instructional structures for the student 2 are shown in Fig. 2(b) and Fig. 2(c). The guide strip 9 can be edited using conventional techniques. Different instruction tapes 9 for instructing the students 2 may be recorded for different tasks or courses.

As shown in FIG. 2(a), in addition to the camera 21a located in front of the student 2, the system 1 also includes cameras 21b, 21c, 21d and 21e respectively located on the right, rear, left and above the student 2. As shown in FIG. 3, the cameras 21a, 21b, 21c, 21d and 21e are selectively connected to the mixer 24 through the camera selector 25. For example, the video signals 26, 27 and 28 from the cameras 21a, 21b, 21c respectively are selected according to the desired view during the course. A replay video recorder 29 replays the guide tape 9 and supplies the reproduced video/audio signal 30 to the mixer 24 . Mixer 24 supplies mixed signals 32a, 32b... to television monitors 3a, 3b... respectively according to option and need. Each mixed frequency signal 32 comprises the video/audio signal 30 of the instructor 8 and the selected video signals 26, 27 and/or 28, which are simultaneously displayed on the screen 5 as a first image 6 and a second image 7 respectively . The camera selector 25 selects the correct cameras 21 a , 21 b and 21 c based on the image 6 of the instructor 8 so that the second image 7 of the student 2 corresponds to the instructor 8 .

The student 2 may wear headphones 33 or listen to a loudspeaker 16, each of which receives an audio signal 34 provided by the mixer 24 as shown, or receives an audio signal 34 from the television monitor 3. Signal 34 is transmitted via an infrared signal or any suitable communication signal (eg, via hardwire). The student 2 can stand in front of the television monitor 3 with earphones 33 and receive the infrared audio signal 34 or listen to the loudspeaker 16 so that he can follow the instructions in the instruction tape 9 and without physical restrictions This is then compared with the image of the instructor 8 on the other half of the split screen 5. Important indications can be indicated by flashing arrows or cursor symbols on the display, or by audio signals or tones.

The student 2 is instructed by the instructional image to complete any orders or instructions received. When the instructional image is played, Student 2 should attempt to imitate. After receiving any given instruction, a time interval should be included in the instruction to enable the student 2 to imitate the instructor 8 . For any given command, other time intervals should be included on the instruction tape 9 for a "comment period" for interpretation. Rest and pause periods are provided on the guide for presentation of the guide image.

As shown in Figure 3, the modification of the aforementioned system is: other sensors 22 and microphones 23 can also input corresponding signals 26a and 26b into the mixer 24 through the selector 25; , computer video 29b and other recordings in computer ROM 29c to provide guidance signal 30. Where appropriate, other sensors 22 may include pressure sensors, position sensors, speed sensors, and the like.

As shown in Fig. 4, another variant of the system 1 is described using a computer control system 36 to provide control signals 37, 38 and 39 for the playback video recorder 29, camera selector 25 and mixer 24, respectively. All other components of the system 1 are the same as those described in FIGS. 2 and 3 . A computer 36 is used to control the operation of the system 1 .

Yet another variation on the operation of the system shown in FIG. 3 is that, for example, the student image can be recorded on the VCR 29 when the instruction image comes from the laser shadow butterfly 29a. A debriefing session may follow the instructional session. The VCR 29 is also capable of recording instructional images along with the student images, which allows for more advanced instruction during reviews or lessons by replaying all or part of the recorded "Lesson" during the "Lesson" session for Student 2 feedback.

When the student 2 uses the system 1, he imitates the instructor 8 by watching a video monitor to compare his posture and movements with the instructor 8. Different tasks or lessons can be learned from a number of different guide strips 9 .

Having thus far described some embodiments of the invention, it will be apparent to those skilled in the art that modifications may be made therein without departing from the scope of the invention.

For example, the system 1 uses a video monitor 3, but instead of the monitor 3, a video projector could be used to provide students 2 with a larger, easier-to-view image.

Instead of one video monitor and three video cameras 21 , 22 and 23 , one video camera and three video monitors may also be used. In this configuration, the video monitors can be arranged at different angles relative to the camera, and when the student turns to a different video monitor, the angle observed by the student's camera should change accordingly.

In the aforementioned preferred embodiments, the system 1 used audio signals. However, it is also possible for the system to use no sound, but only a visual comparison.

The system 1 has been described above with reference to teaching golf, but the system can also be used for teaching other sports such as: baseball, cricket, tennis, etc., as well as in other fields such as medicine, industry, etc.

In another variant, the first image 6 of the instructor 8 is recorded on a compact disc or other device (not depicted) instead of the instruction tape.

Another variation of the system described above is to use an electronic recording device to modify the image 6 of the instructor 8 by providing only the outline of the instructor or making his image faded or translucent. Known video editing techniques can be used to accomplish the above. A system modified using known techniques can merge the outline image of the instructor 8 with the image 7 of the student 2 . In this way, the student 2 can compare his own poses, movements and the modified image of the instructor 8 as they are superimposed.

The system of the preferred embodiment has been disclosed by teaching a student to play golf. The described system can also be used in other non-motor coaching fields. For example, some rules can be taught in the event of movement or movement of a limb or equipment. One such area of application is for teaching maneuvers or procedures to surgeons or physiotherapists.

Another area where the system is used is education. The system can be used to teach writing, or to teach deaf students to speak by contrasting the movements of the instructor.

The system uses a screen that can be divided into many parts as required to generate as many explanatory images as desired, such as: images of the head or a part thereof, torso, limbs, hands, etc., to teach writing, printing, numbers, symbols, Design, medicine, work products, translation, languages, art, painting and drawing, and more. Any or all of the screen may be integrated using conventional techniques with audio overlays, speech or other sounds (synthetic or non-synthetic) for use as the guiding portion of the screen.

Pupils may imitate by sight, sound, writing, spoken words, lip or body expressions, or any suitable part of the body or implement.

The system has been described above with reference to conventional video techniques, but techniques such as programmed imitation instruction may also be used.

There exists a computer technology known as "virtual reality" in which a student puts on a multi-dimensional viewing device (e.g. dilator) and "brings on" other devices to stimulate his other senses so that the student can be in a "virtual environment". "middle. Students can carry sensors that feed signals into the system to indicate student movement. The instructor's movements and guidance are programmed into the system, or recorded by other means, so that students can mimic the instructor in a multidimensional "virtual environment." In such a system, all angles of guidance such as left, right, front, back, top, and bottom angles are covered. Important parts of the instruction can be emphasized using display goggles or flashing arrow or cursor symbols in other displays, or by audible tones and stimulating any part of the student's senses.

Virtual reality representations can provide full sensory feedback because it can stimulate any of the body's senses: sight, sound, smell, touch, taste, and more.

In the virtual space, information about the instructor (his/her image) can be placed next to the student or overlapped with the student image.

In some applications, lectures can also be delivered remotely through devices such as cable television lines, fiber optics or satellite networks that allow for interactive viewing.
