d illustrates schematically a block diagram of a mobile phone according to an embodiment of the present invention.
The mobile phone may be controlled by a processing unit or controller 1, respectively. Different further units may be connected to the controller 1. A cellular transceiver 2a may be connected to the controller 1. The cellular transceiver 2a may be able to transmit signals to a base station of a cellular mobile communication network or to receive signals therefrom by an antenna (not depicted). A low power radio frequency (LP-RF) transceiver 2b may be connected to the controller 1. The low power radio frequency (LP-RF) transceiver 2b may be able to transmit signals via a low power radio frequency mobile communication network or to receive signals therefrom by an antenna (not depicted).
The transmitted and received signals may be digitally coded voice and/or data signals. Voice signals may be processed additionally in an audio unit 3a connected to the controller 1 and to a microphone 3c for recording audio signals and a speaker 3b for generating and playing audio signals. The voice signal may be processed by an analog-to-digital A/D converter (microphone recorded signals) or a digital-to-analog D/A converter (signals to speaker), respectively. A random access memory (RAM) 6a and a read only memory (ROM) 6b may be further provided to the mobile phone and connected to the controller 1. The RAM 6a and ROM 6b may be used for storing program products which are executed to operate the mobile phone. The user interface of the mobile phone comprises a ITU-T keypad 5, a liquid crystal display (LCD) driver 4b and a LC display 4a. In order to identify uniquely the mobile phone a subscriber identification module (SIM) card 6c may be comprised.
The mobile phone may be a mobile phone adapted to connect with a GSM 900 MHz and/or GSM 1800 MHz cellular mobile communication network, but the invention may be also adapted to connect related other mobile communication networks, like UMTS. Further, the low power radio frequency transceiver 2b may be a Bluetooth transceiver 2b. But the low power radio frequency transceiver may also be a wireless local area network transceiver.
The mobile phone, described herein, may comprise the components illustrated in
The first transceiving component C1/C10 may be the Bluetooth transceiver 2b and the second transceiving component C2 may be the cellular (GSM) transceiver 2a.

The block diagram of
The following examples will present a selection of possible embodiments of the method and instructional system for instructing users having mobile terminal devices. The selection of the examples should not be construed as limiting the present invention thereto and should be understood as expounding some but not all of the possibilities of the present invention.
Homework:
A trainer may provide homework exercises to the trainees of a class. According to an embodiment of the invention, the teacher may distribute the respective exercises via his master device 400 to the trainees having slave devices 501, 502, 503 and 504. The exercises may comprise information and questions related thereto. Further, a period of time available for the trainees may also be comprised by the distributed exercises and may for example automatically generate an entry within a built-in calendar of the mobile device for reminding the trainees.
The trainees may generate answers to the questions. The generation of the questions may comprise directly inputting of the answers in the mobile phone, for example the respective mobile phone may be equipped with a typewriter (QWERTY) keyboard and therefore providing adequate inputting means. The trainees may also work out the answers on a further device and transfer the completed answers to the mobile phone for later transmitting same to the master device 400.
At a certain point of time, the answers may have been transmitted to the master device 400 of the trainer. The trainer may transmit the answers on to the central teaching server 301. This central teaching server 301 may provide an automatic processing of the answers and generating of respective evaluations. It may be possible that the central teaching server 301 may only pre-process or may only generate a part of the evaluation. The trainer may support the processing of the answers and the generating of the evaluations.
Further, the respective evaluations may be transmitted from the central teaching server 301 to the master device 400 and distributed thereby to the mobile phones or slave devices 501, 502, 503 and 504 of the trainees.
The central teaching server 301 may provide a selection of possible homework exercises and a trainer may receive exercises by his master device 400 for distribution to the trainees. The trainer may make a request for exercises by transmitting an instruction to the central teaching server 301. Further, the trainer may process the exercises, for example modifying values or adding/removing of questions, before distributing. Moreover, it may be possible for the trainer to distribute different exercises to the trainees by employing a specific recipient information to the homework exercises.
Utterance Training:
The generation of an answer may also comprise the recording of voice and/or speech. Recording of voice and/or speech may be used to train the utterance of a foreign language. A trainer may distribute an electronic book upon his trainees via the trainer's master device according to an embodiment of the above described method for instructing. The trainees may be instructed to repeat a played text passage of the electronic book. The mobile phone of the trainees may comprise an utterance analyzing component. A reference utterance comprised by the electronic book may be compared with the recorded utterance of the speaking trainee. The utterance comparing component may generate a measure of the similarity. In case of a sufficient similarity a corresponding response may be generated comprising e.g. the measure of similarity, a confirmation of success and/or related information and transmitted via the trainer's master device to the central teaching server. The central teaching server may evaluate the response wherein the evaluation comprises for example an adapted electronic book to train especially the utterance of problematic text passages. This evaluation may be re-transmitted via the trainer's master device to the respective concerned trainees according to an embodiment of the method of the present invention.
It may also be possible that the central teaching server performs the processing of the utterance of the trainee. A generated evaluation may comprise a value indicating the quality of the utterance and may request the trainee to repeat or to continue in the exercise of the utterance. A communication network of the sate of the art providing the capability of high network transmission rates may allow evaluation of the recorded utterance at a server connected via the communication network.
Vocabulary Training and Examination:
Vocabulary training and even vocabulary examination may be realized according to the above described embodiment of the present invention.
A trainer may provide instructional tasks comprising a single word or parts of single words. The trainees may be instructed to generate a response, for example by inputting text employing a keyboard connected to the mobile phone or built-in the mobile phone, comprising the translation into another language or a synonym of the provided word. Further, words may have to be completed or added corresponding to a provided part of a word. The evaluation of the vocabulary training may be processed automatically by the central teaching server. The evaluation transmitted from the processing central teaching server to the mobile phone of the trainees via the mobile phone of the trainer may comprise a grading of the training.
According to another example geographical knowledge may be trained. The user of the master device may define different geographical subjects, like a metropolis, a state and a river of the United States of America. These subjects may be distributed to the slave devices further instructing the user to response respective names. Additionally, a initial character of the names of a metropolis, a state and a river may be defined. The users of the slave devices receive a respective instructional task and may input the names into their slave device.
The following table may illustrate an interim state of an inputting task of an user of one of the slave devices. The table shows the subject: metropolis, state and river. The user is instructed to generate a response comprising three answers according to the three different initial characters “P”, “N” and “W” to each subject, depicted in bold face.
A corresponding response may be generated on the slave device e.g. by entering the respective answers using the keypad of the salve device and transmitted to the master device. The master device transmits the received responses to a server corresponding to the above described central teaching server. The server processes the responses, i.e. checks the answers inputted by the users of the slave devices and generates evaluations comprising the checking result. The evaluation may also comprise the further answers of the participating users or may present all legal answers according to the selected subject.
It may be noted that the described method may not be limited to vocabulary examination or geographical knowledge. The presented embodiment may be extended easily to other fields of knowledge.
The above described embodiment relating to geographical knowledge may be extended to a geographical knowledge competition. A computational training of knowledge may be especially interesting in the training of young students.
Again, the user of the master device may define the geographical subjects: metropolis, state and river of the United States of America. The respective instructional task may be distributed upon the slave devices participating on the competition. Since the slave devices offer communication capability, an initial character may be thrown by any one of the slave device and distributed to the other slave devices. The competition starts with the receiving of the thrown initial character. The participators may have to input respective answers to generate the response. If one of the participators finished the task he may stop the competition by transmitting a stopping instruction to the other participators again according to the communication capability of the slave devices. The stopping instruction may instruct the slave devices to complete at once the generation of the responses even if the inputting is not finished. The responses are transmitted to the master device and further to an evaluating server according to the central teaching server. The server checks the answers of the participators comprised by the responses and generates respective evaluations. The performing of the generating of the evaluations ensures a correct evaluation of the responses of the participators.
The evaluation may comprise a grading of the inputted answers in order to allow the participators to compare their performance. The following table represents a possible evaluation content. The table comprises the subjects of the geographical competition (metropolis, state and river), a numbering referencing the participators (part.) and a grading of the participator corresponding to its answers. Herein, 10 points may be granted to a correct answer.
The evaluations may be transmitted to the master device and may be distributed to the slave devices of the participating users. The participators may compare their different checked answers.
The user of the master device may also participate to the competition since the master device may provide also the programming interface:
The instructional tasks which may be distributed by the trainer to the trainees may comprise additionally software tools, code sections containing instructions or program code, respectively. The software tools, code sections containing instructions or program code may be employed for generating the response responsive to the instructional task. The mobile terminal devices receiving the instructional tasks may have a corresponding programming interface. The programming interface may be a proprietary programming interface. It may be noted that programming interfaces may also provide standardized programming interfaces, such as Kjava which is a special programming language developed mobile terminal devices like mobile phones based on the device and system independent programming language Java.
The software tools, code sections containing instructions or program code may provide instructions for displaying information, inputting instruction for generating the response or processing information.
The foregoing description of the exemplary embodiments of the invention has been presented for the purpose of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Many modifications and variations are possible in light of the above teaching. It is intended that the scope of the invention be limited not with this detailed description, but rather by the claims appended hereto.
