In the following, an operational sequence comprising the basic operations according to an embodiment of the invention will be presented. The description of additional operations will follow hereto. In an operation S 100, the method for instructing users may be started. hi an operation SI 10, the master device comprises instructional tasks. The instructional tasks are designated to the users to be worked thereon. An instructional task may be transmitted to each slave device connectable to the master device. Each slave device may receive the same instructional task. It may also be possible to transmit different tasks to the connected slave devices. Therefore, the instructional tasks may comprise a recipient information and the master device may distribute the different instructional tasks according to the recipient information. In order to enable the distribution of instructional tasks upon the slave devices by the master device the devices may be connected to a common wireless communication network. Additionally, further information may be transmitted to or distributed upon the slave devices. The instructional tasks may comprise additional information concerning the dealing with the instructional tasks by the users of the slave devices. These additional information may comprise a time information. The time information may be a period of time within which the instructional tasks may have to be solved by the users. The time information may be also a statement regarding time, e.g. defining the date of returning results corresponding to the informational tasks. The distributed instructional tasks may be received and stored by the slave devices connected to the master device. In an operation SI 20, a user may generate a response according to the instructional task or instructional tasks transmitted from the master device. The response generation may by done by inputting the response directly in the slave device. Further, a generation of the response may involve the usage of further data processing devices. According to an embodiment of the invention, it may be preferably to transmit the instructional tasks comprising additional information to an externally connected device such as a personal computer. Thereon, the instructional tasks may be displayed and the user generates the response. In a following step the response may by transmitted back to the slave device. The kind of generating the response may not be limited by the invention. The response may comprise an identification of the user or its slave device, respectively. The generation of a reliable identification may be described in a following section of the description of the present invention. In an operation SI 30, the user generated response according to the instructional task may be transmitted to the master device. The master device may collect the responses of all slave devices to which an instructional task or instructional tasks have been transmitted. The responses may have to comprise information of their origin and their producer, respectively. This information may be included in or appended to the response by the respective slave device transmitting the response to the master device. It may also be possible to append or include a respective information by the master device to the response. In case of transmission of the response from the slave device to the master device the master device may be able to identify the transmitting slave device and may modify the response such that the response comprises a unique identification of its origin. Further, the response may be encrypted. An encryption may be preferable to prevent the misuse of response in case of a erroneous distributing, in case of confidential content, in case of illegal listing on the distributing communication network and the like. Especially, local wireless communication networks of the state of the art, such as Bluetooth and wireless local area network (WLAN), might not offer reliable secure communication between connected devices. Encrypting algorithm, which are out of the scope of the present invention, are state of the art and available. The encryption of the response may involve a decryption of the response by the master device or by the service provider. The generation of the response, operation SI 20, or the transmitting of the response to the master device, operation S130, may comprise an encryption of the response. The user generated responses of the slave devices may be communicated to the master device via a wireless communication network of the above described type. The master device may store the received responses. In an operation SI 40, the master device may transmit the responses transmitted from the slaves further to a service provider. The response may be transmitted using a communication network. According to the description above, the communication network is not limited to a certain communication network type and may be even a combination of different communication networks linked together, such that the combined communication network may allow devices connected to the different communication networks to communicate and exchange data with each other. In an operation SI 50, the service provider may provide the services of processing the responses and generating an evaluation of the responses. The processing and the generating may be performed automatically. It may also be possible that the service may be performed manually, preferably supported by services provided by data processing devices and their possibilities and abilities. In an operation SI 60, the evaluations may be transmitted to the master device. An identification of the response transmitting slave device or the response generating user which may be comprised by the response may have to be also comprised by the evaluation according to the response. The identification may be necessary to enable the following distribution of the evaluations upon the slave devices such that each of the slave devices may receive only an evaluation according to the response transmitted thereof before. It may be preferable, to make the responses comprising a user/producer or slave device identification anonymous. The master device may include or append an anonymous identification. This may be necessary due to public data protection law. An internal table of the master device may enable to assignment of the slave device or user/producer identification to the anonymous identification employed to distinguishing and identifying of the responses transmitted to the service provider and the evaluations related to the responses generated by the service provider and transmitted to the master device. In an operation SI 70, the evaluations may be distributed upon each of the slave device. The evaluations may comprise further instructional tasks. The providing of further instructional tasks comprised by the evaluations may be an optional feature of the method for instructing users according to an embodiment of the invention. In an operation SI 80, the described method for instruction users according to an embodiment of the present invention may be finished in case of no further instructional tasks comprised by the distributed evaluations. Several operational sequences according to the operational sequence presented in Fig. 1 may be carried out parallel. Parallel operated sequences may not interfere each other. To ensure an interfered operating of several operational sequences the instructional tasks, responses on the instructional tasks and the respective evaluations may comprise further information which may enable to relate the respective transmitted data to a certain operational sequence. Therefore, it may be advantageous for example to code the participating master device since a slave device may be connected to different transmitting master devices in case of participating of the slave device in several independent operated operational sequences comprising different master devices. Additional operations: In an operation SI 04, the instructional tasks which may be distributed upon the slave devices may be received by the master device. A service provider may provide the tasks on a corresponding request of the master device before the distributing. In an operation S105, the instructional tasks may be processed before distribution upon the slave device. The processing may be performed by inputting instructions by the user of the master device therein. It may also be possible to transmit the instructional tasks to further connected terminal devices offering certain adapted functions and features for processing the instructional tasks. A processing of the instructional tasks may comprise a modifying , an adapting or an individualising of the instructional tasks. A modifying and adapting of the instructional tasks may be preferable in case of receiving of the instructional tasks from a respective service provider. By modifying or adapting the instructional tasks, the tasks may be adapted to certain requirements according to the distributing situations. Moreover, a service provider providing instructional tasks may provide a kind of basic instructional tasks. The user of the master device may be able and allowed to transform the basic instructional tasks to the desired structure. An individualisation or personalisation may be preferable in case of distributing different individual instructional tasks upon each of the slave devices. The processing of the instructional tasks may comprise encryption of the instructional tasks. An encryption may be preferable to prevent the misuse of instructional tasks in case of an erroneous distributing, in case of confidential content, in case of illegal listing on the distributing communication network and the like. Especially, local wireless communication networks of the state of the art, such as Bluetooth and wireless local area network (WLAN), might not offer reliable secure communication between connected devices. Encryption algorithms, which are out of the scope of the present invention, are state of the art and available. Accordingly, encrypted instructional tasks may have to be decrypted by the receiving slave for further processing and/or generation of a response. In an operation SI 06, the instructional tasks may be processed to comprise an identification of the receiving slave device. The identification of the recipient may be necessary in case of distributing different individual instructional tasks to the slave devices. Further, it may be possible to distribute instructional tasks to only a selection of the plurality of slave devices connected to the master device. The identification of the recipient may ensure a distribution only upon the selected slave devices. The individual identification and individual instructional may be also preferable in case of encryption of the instructional tasks according to the utilised encryption algorithm. In an operation SI 15, the reception of an instructional task by a slave device may be confirmed by re-transmitting a respective confirmation from the slave device to the master device. The confirmation may comprise information on the receiving time but may also be used to ensure an error-free transmission of the instructional task, e.g. by comprising a checksum. In an operation S125, the response may comprise an identification of the slave device of the user/producer of the response. The response may have to be relatable or assignable to the slave device or user/producer by the master device. The identification of the slave comprised by the response may be passed over to the respective evaluation responsive to the response during the processing of the response and generating of the responsive evaluation according to the operations S150. The passed over identification may enable the master device to distribute the evaluations upon the respective concerning slave devices. hi an operation S135, the reception of a response by a master device may be confirmed by retransmitting a respective confirmation from the master device to the respective slave device. The confirmation may comprise information on the receiving time but may also be used to ensure an error-free transmission of the response, e.g. by comprising a checksum. In an operation SI 55, the processing of the responses by the service provider and the generation of the evaluation may comprise further operations. For example, the service provider may generate a request directed to a further service provider and may receive a corresponding request response therefrom. The processing and generating of the service provider is adapted to the responses corresponding to the instructional tasks. Examples will be given in the following description of embodiments according to the present invention. h an operation SI 75, if the evaluation distributed by the master device upon each slave device comprises further new instructional tasks the operational sequence may be continued with operation SI 20, indicated in Fig. 1.
