Description

SPECIFICATION

VIRTUAL REALITY BASED REMOTE LEARNING SYSTEM AND METHOD The present invention relates to remote learning methods and particularly virtual reality based remote learning methods and systems for realizing said methods.

PRIOR ART Remote learning methods are systems which are substantially time-saving both for students and for instructors. Such systems essentially comprise digital learning materials (videos, questions, books, etc.) and said materials are shared with the student with the help of the system servers through internet under the control of the instructor. Of course, during said sharing, there is an interaction although said interaction is limited. For instance, the instructor and the student have live communication or video talk facility, and the students can answer various multiple choice questions.

In the recent years, such systems are tried to be combined with virtual reality applications. In virtual reality applications, the users may intervene in the objects designed in the virtual learning medium by means of using suitable equipment. For this reason, in general, a virtual reality eyeglass, which displays the designed digital medium on its screen, is worn, and movement sensors are used which will sense the movements in different regions like hand, arm regions of the body. The use of virtual reality applications for learning purposes is known in the prior art. For instance, in the patent application KR101307609, a virtual learning application for scuba diving purpose is described. In this system, equipment for providing the sense of pressure and fans for providing perception of diving are used. In the patent application TR200903142, a system is described which integrates movement sensing and virtual reality with kinematic and computer aided design (CAD) for instance in order to evaluate an engineering design.

One of the most basic deficiencies in the present virtual reality based learning applications is that the interaction between the instructor and student is limited, and that the systems used has a very high cost. Thus, the advantage of these systems can be used by a very narrow group of people. BRIEF DESCRIPTION OF THE INVENTION

DETAILED DESCRIPTION OF A PREFERRED APPLICATION OF THE INVENTION

In this detailed description, the subject matter system and method are explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.

The subject matter system essentially provides instantaneous interaction of at least one instructor (20) and at least one student (90) in a virtual reality medium (130) for training purposes, where said instructor (20) and said student (90) are in different locations.

Accordingly, in the instructor location (10), there is essentially an instructor movement sensing system (30) for sensing the movements of the instructor (20), an instructor display unit (50), and an instructor terminal (40) connected to said instructor movement sensing system (30) and said instructor display unit (50). In a similar manner, in the student location (80), there is essentially a student movement sensing system (100) in order to detect the movements of the student (90), a student display unit (120) and said student movement sensing system (100), and there is a student terminal (110) connected to the student display unit (120).

The whole communication between the instructor terminal (40) and the student terminals (1 10) is realized through a server group (70) by means of a wireless communication network (60). Said server group (70) essentially comprises an application server (71), a virtual content server (72) and a backup server (73). In the application server (71), there is a loaded virtual training application, and both the instructor (20) and the student (90) connect to said application server (71), and they install said virtual learning application to their own terminals. In the virtual content server (72), at least one but preferably a plurality of virtual learning medium (130) is loaded for different purposes, and after the virtual learning application is installed to the student terminal (110) and the instructor (20), the related virtual learning medium (130) is downloaded from the virtual content server (72). Another important task of the virtual content server (72) is to instantaneously transfer all of the movement sensing data and the other predetermined data (like voice, written, real camera images), received from the instructor (20) and student terminal (1 10), to the opposite party. By means of this, all movements of the instructor (20) and the student (90) are instantaneously reflected to the opposite party in the virtual learning medium (130). For instance, when the instructor (20) moves his/her hand, the hand of the virtual character (131) of the instructor moves instantaneously in the virtual learning medium (130) viewed by the student (90). Such an instantaneous communication provides a much more realist and effective interaction. Another task of the server group (70) provides recording of the whole training session. Therefore, backup server (73) is used which is in instantaneous communication with the virtual content server (72), and thus, all training sessions are recorded and when required, this information is provided to the authorized terminals. In an alternative application of the present invention, a single server, which realized two functions, can be used instead of the application and virtual content servers (71 , 72). Or in very intense applications, pluralities of application and virtual content servers (71 , 72) can be used in cluster form. With reference to Figure 2a, the instructor movement sensing system (30), used in the subject matter invention, preferably comprises at least one of an instructor hand-arm movement sensor (31), an instructor head movement sensor (32), an instructor body movement sensor (33) and at least one of instructor wearable movement sensor (34). The hand-arm movement sensor can essentially sense the hand, arm and finger movements of the user in a three-dimensional plane, and said sensor transfers all of said movements to the instructor terminal (40) as digital movement data. For instance, the instructor hand-arm movement sensor (31) can sense in case the instructor (20) extends his/her arm and makes a gripping movement by means of his/her fingers. The product of the LeapMotion Company can be given as an example to the hand-arm movement sensor.

The head movement sensor can sense the head movements of the user in a three- dimensional plane, and it transfers all of these movements as digital movement data to the instructor terminal (40). For instance, if the instructor (20) turns his/her head at a specific angle or lifts his/her head upwardly, this movement can be sensed by the instructor head movement sensor (32). In a preferred application of the present invention, as an example to head movement sensor, virtual reality eyeglasses can be given which are used as example to the head movement sensor and which can sense the head movements by means of the gyroscope system included. The virtual reality eyeglasses, produced by the Oculus Company, can be given as an example to such a product. Instead of a relatively higher cost virtual reality eyeglass, the instructor or the student can produce the virtual eyeglass chamber from carton, and a smart cellular phone, where an application dividing the screen to two pieces is loaded, can be placed into the section of this chamber which corresponds to the eyes. By means of the gyroscope characteristic of the smart cellular phones, in this method, the head movements of the instructor can be sensed. As an example to this application, the Google Cardboard product and the related software application can be given which is produced by the Google Company and which is used together with smart cellular phones.

The body movement sensor can sense all items in the body of the user, and the general position of the body, and it transfers all of these movements as digital movement data to the instructor terminal (40). For instance, in case the instructor (20) moves, for instance in case the instructor (20) walks forwardly, he/she lifts his/her arm upwardly, and he/she moves his/her leg, this movement can be sensed by the body movement sensor (33). In a preferred application of the present invention, the product of the Microsoft Company with Kinect trademark can be given as an example to the body movement sensor. The wearable movement sensor can sense the movements of some items in the user body in a similar manner to the body movement sensor, and it transfers all of said movements as digital movement data to the instructor terminal (40). The wearable movement sensor comprises at least one of glove sensor fixed to hands, and sensors which can be fixed to elbows, knees and shoulders. Depending on the type of the sensor used, pluralities of movements, like lifting the arm of the instructor (20) upwardly, moving the leg, and rotating around the own axis thereof, can be sensed by the instructor wearable movement sensor (34).

In a similar manner, the student movement sensing system (100), provided on the student side, comprises at least one of student hand-arm movement sensor (101), student head movement sensor (102), student body movement sensor (103) and student wearable movement sensor (104). Since the operation manner of all of these items is the same as the operation manner of the items on the instructor (20) side, a description will not be given here again.

With reference to Figure 2b, as the instructor terminal (40) in the subject matter system, at least one of an instructor personal computer (41), an instructor smart cellular phone (42) or an instructor tablet (43) can be used. In a similar manner on the student side (Figure 2e), as the student terminal (1 10), at least one of a student personal computer (11 1), a student smart cellular phone (112) or a student tablet (113) can be used. With reference to Figure 2c, in the subject matter system, an instructor terminal screen (51) or instructor reality eyeglass (52) can be used as the instructor display unit (50). The instructor terminal screen (51) can be the standard or touch-screen of the instructor personal computer (41), the instructor smart cellular phone (42) or the instructor tablet (43). As the instructor virtual reality eyeglass (52), again a product like Oculus can be used, or Google Cardboard solution, which functions together with smart cellular phones, can be used. Since the items, related to the virtual reality eyeglass (52), are mentioned above, they will not be detailed here more.

In the light of this pre-information, an exemplary application of the present invention is realized as follows. In this exemplary application, the object is to teach chess to the persons, and a virtual learning medium designed accordingly has been loaded to the virtual content server (72). In said virtual learning medium (130), as the virtual object (133), there is essentially a chess board, and chess pieces provided thereon. Prior to the learning session, the instructor (20) and the student (90) access to the application server (71) through the wireless communication network (60) by means of the user terminals, and afterwards, they install the virtual learning application to their own user terminals. Afterwards, they download said virtual learning medium (130) to their own user mobile terminals through the virtual content server (72). In another application, without any download process, the instructor and student mobile terminals provide authorized access to the virtual content server (72), and all of the processes are realized on the virtual content server (72). After this preparation, a representative learning session is realized as follows according to a preferred application given in Figure 3. In this application, the instructor uses the instructor personal computer (41) as the user terminal, and the student uses the student personal computer (11 1) as the student user terminal. As the movement sensing system, an instructor hand-arm movement sensor (31) and a student hand-arm movement sensor (101) are used which are connected to the personal computer and which are preferably LeapMotion devices. Accordingly, for instance, when the student (90) moves his/her hand in a suitable manner for moving the chess piece which is a virtual object (133) in the virtual learning medium (130) and when the student (90) moves his/her fingers for holding the related piece, the hands and fingers of the virtual character (132) of the student, existing in the virtual learning medium (130), are moved by means of the LeapMotion device. Thus, the student can lift the chess piece in the virtual learning medium (130) and he/she can put said chess piece to another location on the chess board. The interaction between the hands of the student virtual character (132) and the instructor virtual character (131) and the chess pieces (virtual object (133)) may become possible by means of the virtual learning application loaded in the user terminals. Preferably, but not limited to this, the virtual learning application is essentially based on coordinates in the virtual learning medium, and said application decides to realize interaction or not by taking the coordinates in the virtual learning medium as a base.

By means of the virtual content server (72), all of these movements are instantaneously transferred to the personal computer (41) of the instructor, and thus, the instructor can see the move of the virtual character of the student in the virtual learning medium illustrated on the screen of the personal computer (41). Accordingly, for instance, if the instructor recognizes that the student (90) moves the chess piece in an erroneous manner, the instructor can immediately intervene this in the virtual learning medium. In more details, when the instructor (20) moves his/her hand in a suitable manner for moving his/her hand, the hand and fingers of the virtual character of the instructor move by means of the LeapMotion device provided on the instructor side. Thus, in the virtual learning medium, the instructor can lift the related piece from the wrong location, and can put said piece to the correct location on the chess board.

Meanwhile, the virtual content server (72) instantaneously transfers all of said movements to the personal computer (111) of the student, thus, the student (90) can see the move made by the instructor virtual character and illustrated on the screen of the student personal computer (1 1 1). Voice or written messages can be included in all of these interactions. Therefore, a microphone which can be fixed externally or which is provided internally in the user terminals will be sufficient and an optional earphone set will be sufficient.

In the application illustrated in Figure 4, instead of the instructor and student personal computer (41 , 1 11), the instructor and student cellular phones (42, 112) are used, and instead of the instructor and student personal computer (41 , 11 1) screen, the virtual reality eyeglasses (52, 122) are used as the display unit. Accordingly, they connect the instructor hand-arm movement sensor (31), the student hand-arm movement sensor (101), and the student virtual reality eyeglass (122) and the instructor virtual reality eyeglass (52) to their own cellular phones where the abovementioned required applications are loaded. Since the operation is substantially same as the application illustrated in Figure 3, no detailed description will be given here, only the differences and the advantages of said differences will be described. The greatest advantage of the virtual reality eyeglass (52) is that it provides a much more realist experience (immersive environment) when compared with the personal computer (41) screen. Of course, this provides a favorable contribution to the efficiency of the learning session. Another advantage is that by means of the gyroscope characteristic in the virtual reality eyeglass, the head movements of the instructor and the student (90) can be monitored and they can be transferred to the virtual learning medium (130). Thus, for instance, the instructor can see which direction the student (90) looks at and even which piece the student (90) looks at, and thus, he/she can transfer some commands and warnings to his/her student (90) without making additional move. In the virtual learning medium (130), indicators like an arrow, which extends from the head of the virtual character towards the target, can be used for providing understanding of the looking direction by the opposite party.

As described in the prior sections of the detailed description, as a lower cost solution, the Google Cardboard product and the related software application, produced by the Google Company, can be used together with the smart cellular phones (42) instead of the virtual reality eyeglass (52).

In the applications of the invention where Google Cardboard and smart cellular phone are combined, the student or the instructor may have to see the real world at the same time. For this reason, the front camera of the cellular phone is used, and when desired, the real medium image obtained from this is displayed in a small window or in full-screen manner on the screen of the smart cellular phone. By means of this camera image, the user can see every direction to which he/she turns his/her head. In another application, the images existing on the personal computer (41 , 1 11) of the instructor and/or student are transferred to the smart cellular phone by using software like TeamViewer. Thus, even if there is no software related to virtual reality applications on the smart cellular phones, it can be used in accordance with the subject matter object by taking the images existing in the personal computer.

In another application of the present invention, one instructor eye movement sensor (35) and one student eye movement sensor (105) can be used which sense the eye movements of the instructor and the student beyond the movements of the head. Thus, both the instructor (20) and the student (90) can look at a location without having to turn his/her head; and even this looking point can be shown to the other party with a suitable marking. As an example to this marking, an arrow exiting the head or eyes of the looking person can be given.

In Figure 5, an instantaneous representative view of the training session is given as viewed by the instructor. Accordingly, in the virtual learning medium (130), there is a chess board as the virtual object (133) and there is a chess piece provided on the chess board. The virtual character (132) of the student comprises the head, body, arm, hand and fingers. The instructor preferably only sees the hand and fingers and a section of the arm of his/her own virtual character (131). The student (90) can see the instructor from his/her side in the same manner.

In Figure 6, a different application of the present invention is described. In this exemplary application, the purpose is to give Pilates lesson to the persons, and a virtual learning medium prepared accordingly is loaded to the virtual content server (72). In said virtual learning medium, generally there is Pilates mat as the virtual object (133). When the preparation process in the user terminals is the same as the application described in Figure 3 and 4, it will not be given here in details. In this application, the instructor and the student use a personal computer (41) as the user terminal, and they use body movement sensor (33, 103), connected to the personal computer (41) and preferably which is a Microsoft Kinect device, as the movement sensing system. Accordingly, for instance, when the student (90) opens his/her hands and arms simultaneously, the virtual character of the student is going to make the same movement in the virtual learning medium by means of the Kinect device. The virtual content server (72) instantaneously transfers all of said movements to the personal computer (41) of the instructor, and thus, the instructor can see the move, made by the virtual character of the student, on the screen of his/her personal computer (41). Accordingly, for instance, when the instructor detects that the student makes a false gymnastic movement, the instructor can instantaneously intervene in this problem in the virtual learning medium. In more details, the instructor warns the student (90) with a voice command, and he/she tells the student (90) to follow his/her movements. Afterwards, when the instructor makes the correct movement with his/her body, this movement is sensed by the Kinect device on the instructor side, and it is transferred to the personal computer (41) of the student through the virtual content server (72). Thus, the student (90) can observe the body movement of the virtual character of the instructor on the screen of the student personal computer (11 1).

Such training has pluralities of advantages when compared with real image trainings which can be realized through camera. First of all, the training can be made much more efficient by means of pluralities of additional features which can be added to the virtual learning medium. For instance, there is a cassette object in the virtual learning medium, and when the instructor touches said object with his/her virtual hand, a learning video specific to said movement can be created. Secondly, when the parties do not want to see their real images due to various reasons, such a learning system will be very useful. Moreover, since the bandwidth used will be much lower when compared with the real image, a more rapid and uninterrupted communication will also be possible. Besides, some risky teachings may firstly be realized in the virtual medium for preventing injuries, and after it is understood that the student has grasped the procedure to be applied in a clear manner, the passage to the real medium can be realized.

In Figure 7, an instantaneous representative view of the learning session as viewed by the instructor is given. Accordingly, there is Pilates mat as the virtual object (133) in the virtual learning medium (130), and the virtual character (132) of the student is on the Pilates mat. Said virtual character (132) essentially comprises head, body, arm, hand, leg and feet. The instructor can preferably only see some section of the arm and hand of his/her own virtual character (131). In the same manner, the student (90) can see the instructor from his/her side. In the applications illustrated in Figure 3, 4 and 6, the instructor (20) or the student (90) can use fixtures which are different from each other. For instance, the instructor may use the fixture given in Figure 4, and the student (90) may use the fixture given in Figure 3, or the instructor may use the fixture given in Figure 5, and the student may use the fixture given in Figure 3. These alternatives can be developed depending on the application requirements and personal capabilities. In alternative applications of the present invention, there may be more than one person particularly on the student side. The positions of all these persons in the virtual learning medium are determined beforehand, and thus, the instructor sees all these persons instantaneously, and he/she may follow the movements of all of them. The best example to this can be the designing of the virtual learning medium as a classroom. In this virtual classroom, there is an instructor stand and pluralities of desks opposite to said stand. The desk of each student, who will attend the virtual learning session, is determined and when the system is connected, the predetermined virtual character of said student is formed at said desk. By means of the subject matter whose operational details are given above, after this moment, all of the movements of that person can be detected by the instructor connected to the virtual learning session.

By means of the subject matter system, training in very different fields can be provided in a very effective manner. As additional examples to said teachings, industry-oriented teachings (assembly or welding teachings), and teachings (critical experiments, bomb disposal, vehicle usage) which are dangerous when sufficient competency is not provided, can be given. Of course, the number of said examples can be substantially increased.
