Device, system with such devices, method of implementing the system and computer program product for implementing the method

The present invention relates to a portable electronic device according to the preamble of patent claim 1, a technical system with such devices, a method for realizing such a technical system and a computer program product for selectively implementing such a method.

At the present time, a variety of portable electronic devices with touch screen for image representations of the device and controls the image representations of the device and the device using the image representations by touching and without touch gestures of the touch screen, for example, with one or more fingers of a user of the device known. Such devices are made for example as a mobile phone, smartphone, iPad, eBook reader, personal digital assistant device (PDA), navigation device, tablet PC and so on. Such devices can be controlled, for example, with finger pointers with one or more fingers on the touch screen. Not only simple touch on the touch screen is used, but also touch gestures such as wiping, for example, with your finger on the touch screen. Also, a divergence or contraction example of two fingers on the touch screen is possible as an example touch gesture. The result of such touches or touch gestures is a corresponding control of the image display or the functions of the device or the programs active on the device.

Meanwhile, such devices are frequently found within a narrowly defined environment. All of these devices work autonomously, that is, they are only self-referential. This also applies to the respective touch screens of the respective devices. In addition, the touch screens of each device are often very small, because the devices themselves are designed very small. On the other hand, many picture contents are often to be displayed on the touch screens, which results in that individual presentation details are very small.

For example, if text is to be entered at the top of the touch screen on the touch screen of a relatively small smartphone using a soft keyboard displayed at the bottom of the touch screen, the visible text area will be smaller than it should be because the soft text is displayed Keyboard image area of the touch screen for the text area is no longer available. Conversely, the area for the display of the soft keyboard is also reduced and thus the soft keyboard can only be displayed correspondingly small. Remedy is achieved when a separate, externally connectable keyboard is used, but this means a separate second device and is complicated and expensive.

Similar problems exist if the contents of browser windows on the touch screen and possibly even with text input are displayed. In particular, the image contents of browser windows are often very complex, so that the individual details are shown only very small. The mentioned soft keyboard represents a self-contained control area or image content which is not bound to a fixed position within an image representation. He may also be moved to another position. Such closed control areas or image contents occur frequently and frequently also bundled in the course of image content to be displayed. However, the shifting of such closed control areas or image contents is only within the existing touch screen possible, so that an increase of the one completed control area or image content is always at the expense of the size of the other closed control areas or image content. In order to avoid this problem, it is possible not to change the size of the other closed control areas or picture contents, but to temporarily put them in the background and, if necessary, in the foreground again. The disadvantage is that many switching and that all image information is not constantly available simultaneously.

On the other hand, as already mentioned above, often a plurality of devices mentioned above are simultaneously active in a narrowly defined environment, but in each case as a so-called stand-alone device. The touch screens of the respective individual devices are not available for a screen display of the other devices with various advantages. The object of the present invention is therefore to provide a device, a technical system with such devices, a method for realizing the technical system and a computer program product for implementing the method, with which the various advantages can be utilized by changing the screen display of a single device concerned be made.

This object is achieved with respect to the device, starting from a device of the type described above according to the invention that the device in question has the characterizing features of claim 1. This object is further achieved with respect to the technical system according to the invention that the technical system has the features of claim 10. This object is also achieved with respect to the method for realizing the technical system according to the invention that the method has the method steps indicated in claim 13. This task will eventually be discussed with reference to the computer program dukt according to the invention achieved in that the computer program product has the features of claim 22.

With regard to the device according to the invention, the object is achieved in that the device according to the invention has a synchronization interface for such a synchronization simultaneously with at least one single further device such that a total touch screen consisting of the touch screens of the individual synchronized with one another for the device according to the invention Devices is formed such that at least parts of an image representation of the device according to the invention controlled by the device according to the invention on the touch screens of selected synchronized with each other other devices as originally functional are displayed.

The devices according to the invention therefore do not necessarily work only as so-called stand-alone devices, but possibly also interdisciplinary with other devices according to the invention. The components of existing devices according to the invention are advantageously used in this way and not only remain potentially because they are interdisciplinary unused. With regard to the technical system, the object is achieved in that a plurality of such synchronized devices according to the invention is provided that for one of the synchronized devices according to the invention a total touch screen consisting of the touch screens of each synchronized devices is formed such that at least parts of a Image representation of a device according to the invention controlled by the one device according to the invention on the touch screens of selected synchronized with each other sated devices as originally on one device according to the invention are operationally displayed. The advantage of such a technical system is that, for example, when text is to be entered on the touch screen of a device associated with the technical system with a soft keyboard, in this case, for example, an upper portion of the associated touch screen for the text and a lower portion for the display of the soft keyboard is used, for example, the soft keyboard on the touch screen of another device of the technical system can be swapped out and there permanently displayed maximum magnification, while on the original device according to the invention there the entire touch screen for text display, for example either with even more displayable text or with even larger letters or both at the same time is usable. The soft keyboard is as functional as it was originally functional, that is, it still reacts in a corresponding manner, for example, to corresponding finger touches.

It should be noted at this point that the soft keyboard is only representative of any other logically closed control areas or screen display areas, of which, moreover, at the same time several can be present on one and the same screen display. In such a case, one or the other completed control area or screen display area or even several such closed control areas or screen display areas may be simultaneously paged out to one or more other devices according to the invention for display there on the local touch screens. Regardless of how distributed the completed control areas or screen display areas are outsourced, they remain available for the original device according to the invention touch-sensitive. Another example is the display of high resolution images on the touch screen of a subject device of the invention. In accordance with the invention coupled touch screens of devices according to the invention in one According to the system according to the invention, for example, such images can be drawn up completely or else only partially with a corresponding enlargement effect via the touch screens of the devices participating in the technical system. The reverse is possible accordingly. Further, for example, by corresponding touch gestures such as wiping or rotating and so on, a corresponding shifting, rotating, tilting and so on are possible, much as in the original touch screen.

It is again confirmed that outsourcing of relevant screen displays does not necessarily mean that in each case a complete outsourcing must take place. It can also be only partial outsourcing, so that, for example, only a part of a relevant screen display appears on a different touch screen. The other part is meanwhile still displayed on the original touch screen. In sum, floating out of concerned closed screen display areas between different touchscreens is possible, and interruptions in the flow of swapping may also occur.

With regard to the method for realizing the inventive technical system according to the invention, the

Problem solved according to the invention with the following method steps:

- Switching of devices according to the invention in an either active or standby mode for mutual synchronization such that for one of the synchronized devices according to the invention a Gesamtvorührungsbild- screen consisting of the touch screens of each other synchronized with each other devices according to the invention is formed such that at least parts an image representation of a device according to the invention controlled by the one device according to the invention on the touch screens of selected synchronized other inventive according to the original equipment as originally functional,

Recognizing in each case other devices according to the invention which are in the said active or standby mode, starting from in each case one of the devices according to the invention,

Preparing a synchronization with each other in the said active or standby mode and recognized as such inventive devices starting from each one of the devices according to the invention,

- Synchronizing with each other in the said active or standby mode and recognized as such inventive devices starting from each one of the devices according to the invention, and

- Picture represent a each for a respective inventive device due to the distributed image representation on the touch screens of the synchronized with each other for this purpose devices according to the invention resulting image representation by the respective device according to the invention. Devices according to the invention, which perform such method steps, advantageously form such a favorable technical system which utilizes potentially existing resources which have hitherto been used only in relation to individual devices, and which now cover devices.

With regard to the computer program product for realizing the method according to the invention when using the computer program product on a device according to the invention, the object is achieved according to the invention by a computer program product having program code means forming a computer program for selectively implementing the method according to the invention.

Such a computer program product has the advantages that it can initially be handled independently of a device according to the invention as described above, that it is then applied at a later time to an inventive device as described above or into such a device Device can be introduced with the advantage of the possibility of there optional advantage of the computer program product, and that it is the benefit of an inventive device this device according to the invention capable of carrying out the above-described inventive method again with the advantage that the relevant Device according to the invention together with corresponding other such devices according to the invention to realize the technical system according to the invention with the associated advantages described above.

Advantageous embodiments of the invention are the subject of dependent claims.

The use of means providing a synchronization interface for wireless synchronization provides the advantage that the synchronization can be performed independently of a separate trunk, thereby giving very free handling to existing devices. In addition, the existing devices do not necessarily have to be located in a very close mutual environment. Wireless interfaces also allow for longer distances between devices.

For wireless interfaces already well-known interfaces such as Bluetooth,

WLAN (Wireless LAN), ZigBee, NFC (Near Field Communication), Wibree, VLC (Visual Light Communication) or WiMAX interfaces. However, other wireless interfaces are also possible. Furthermore, several different wireless interfaces can be used at the same time. The scope of the invention is thereby additionally increased.

Wired synchronization interfaces provide a very high degree of synchronization security and security in maintaining mutual synchronization. Known wired interfaces such as a USB interface can be used for this purpose. Other wired interfaces can also be used. With the help of a mechanical link, individual devices according to the invention can also be mechanically connected to one another, so that a device unit with a solid structure results. It is advantageous if this mechanical link is articulated. As a result, devices according to the invention can also be fixed to one another at a predetermined angle. If necessary, they can also be handled like a device with a lid.

A mechanical link has the further advantage that it can be readily combined with a wired interface.

The invention can be used to particular advantage in devices such as minicomputers, mobile communication terminals, mobile phones, smartphones, iPads, ebook readers, PDAs, navigation devices, tablet PCs, or equivalent devices, all of which have the problem of a small screen display but are very numerous in circulation are and often have touch screens.

In providing means for control of synchronized devices by eye movements, speech and / or body movements, use of the invention is possible even in the presence of corresponding impediments.

If the devices according to the invention and used according to the invention are arranged in a matrix structure, a type of large screen can be realized in this way. With the detailed method steps, a compact realization of the synchronization and use of relevant devices according to the invention takes place. The detailed process steps include in particular the following group process steps:

Accepting a foreign ready signal which signals a foreign willingness to form the technical system and which can be assigned to the sender when the foreign ready signal is received,

Issuing a self-acknowledgment signal which signals the receipt of a foreign ready signal and which can be assigned to the sender,

- accepting a foreign acknowledgment signal upon arrival of the foreign acknowledgment signal;

Requesting information to be entered manually via an optionally specific master or slave assignment and, in the case of a specific slave assignment, via an optionally specific matrix image segment assignment after receiving at least one single acknowledgment signal,

Interactively with the knowledge of the sender of acknowledged acknowledgment signals, check the assignments of the acknowledgment sender and the own assignment for the presence of only a single master assignment,

With knowledge of the sender of acknowledged acknowledgment signals, request the matrix image segment assignments of the acknowledgment signal transmitters with their own master assignment;

Synchronizing interactively the touch screens of the confirmation signals emitting devices into a single overall touch screen for the device with master assignment depending on the specific master, the concrete slave and the concrete matrix image segment assignments.

In the case of devices according to the invention connected in a so-called active mode, the following detailed method step contributes to the realization of a synchronization of devices according to the invention: - Issuing an own standby signal, which can be assigned to the sender, for the signaling of own readiness to form a technical system according to one of Claims 10 to 12.

It is advantageous, in particular, if method steps take account of error handling, which is given by the following method step: reporting an error with or without correction possibility and with or without change to a predefined operating state at least when detecting the presence of more than two master orders. It is also particularly advantageous if the synchronized devices interrogate and transfer specific parameters so that they can be taken into account in the image display on so-called foreign devices. Such takes into account the following group process steps, namely synchronized devices according to the invention, which have a so-called master assignment and control an image representation of the total touch screen obtained by the synchronization, which is optionally formed with touch screens of technically different devices according to the invention:

Request with knowledge of the sender of acknowledged acknowledgment signals from image display parameters of the touch screens of the devices associated with the acknowledgment sender with their own master assignment,

- Splitting an image to be displayed at least in part on the individual touch screens of the extended overall touch screen with its own master assignment, and:

Consider respectively the image display parameters of the respective touch screens of the respective devices of the extended overall touch screen when splitting one image to be displayed on the individual touch screens (2) of the extended overall touch screen.

The invention will be explained in more detail with reference to a drawing. Show:

Figure 14 is a technical system according to the invention formed with two technical devices according to the figure 1 in

Front view and a second operating situation, and Figure 15 is a technical system according to the figure 14 in front view and a third operating situation.

The device 1 illustrated in FIG. 1 has a touch screen 2 for image representations 3 and first means 4 on the one hand for performing image representations 4 on the touch screen 2 and on the other for controls of image representations 3 and / or of the device 1 via the image representations 3 by touches with and without touch gestures of the touch screen 2, for example, with one or more fingers of a user of the device 1. The controls of the image representations 3 and the device 1 cause a modification of the image representations 3 and / or operating the device 1 on the Bilddarstelllungen. 3

Modifying the image representations 3 means, for example, that suitable image display parts or image display regions of the image representations 3 can be displaced, enlarged and so on, for example with respect to their location placements on the touch screen 2 with finger touches with and without touch gestures such as swiping, tapping, dragging and so on so on.

Operation of the image representations 3 means, for example, that suitable image display parts or image display regions of the image representations 3 are actually used for example with respect to starting application programs, for example with finger touches such as double-tipping and so on.

The device 1 further has a synchronization interface 6 formed with second means 5. The synchronization interface 6 allows the device 1 for the purpose of synchronization with at least one single similar further device 1, a bidirectional data communication. 7 To effect this synchronization, the device 1 has third means 8 which, in cooperation with the first means 4 and the second means 5, control the synchronization with at least one single similar further device 1 in such a way that a total touch screen for the device 1 is obtained 9 (Figures 7 and 8) consisting of the touch screens 2 of the individual synchronized devices 1 is formed such that at least parts of an image display 3 of the device 1 controlled by the device 1 on the touch screens 2 selected synchronized with each other other devices 1 such originally functional on the device 1 can be displayed.

FIG. 1 shows a synchronization interface 6, which is formed by means 5, which allows wireless bidirectional data communication 7.

Examples of such wireless bidirectional data communication interfaces are the well-known Bluetooth and / or WLAN and / or ZigBee and / or NFC and / or Wibree and / or VLC and / or WiMAX interfaces. Other wireless interfaces, however, may also be usable. The synchronization interface 6 can also be formed instead of or additionally with means 5, which allows a wired bidirectional data communication 7. This case is not shown in detail in the drawing. As an example of such a wired bidirectional data communication interface may be mentioned the well-known USB interface. However, other wired interfaces may also be usable. The device 1 can be combined with a mechanical link 10 (FIG. 15), so that a mechanical connection to external components, such as, for example, such a further device 1, can thus be realized. The mentioned mechanical link 10 can be combined in an advantageous manner with means not shown in detail in the drawing for the formation of the wired synchronization cut parts 6. Thus, two means for two different functions are advantageously realized with a means for two different functions.

As basic devices for the formation of devices 1 according to the invention, for example, today known minicomputers, mobile communication terminals, mobile phones, smartphones, iPads, eBook readers, PDAs, navigation devices, tablet PCs and so on serve. In the drawing, a smartphone is selected as such a base unit.

The device 1 may also comprise means suitable for controlling the device 1 with eye movements, speech, body movements and so on. In the present drawing such means are not explicitly indicated.

FIG. 2 shows a technical system 11 with devices 1 described above in a combined view. The technical system 11 shown in FIG. 2 comprises three devices 1, the devices 1 being respective smartphones 1a, 1b and 1c. Each of these devices 1 has a correspondingly wide or less wide wireless transmission range 12a, 12b and 12c with respect to its synchronization interface 6 for wireless bidirectional data communication 7. In detail, the transmission range 12a belongs to the device 1a, the transmission range 12b to the device 1b and the transmission range 12c to the device 1c.

As FIG. 2 further shows, the transmission ranges 12a and 12b of the devices 1a and 1b mutually overlap, so that the devices 1a and 1b respectively can perform a bidirectional data communication 7 to the other device 1b or 1a, respectively. Although the device 1c is located within the transmission ranges of the devices 1a and 1b according to FIG. 2, the device 1c can indeed receive the transmissions of the devices 1a and 1b. The transmission range of the device lc does not extend beyond the devices la or lb, so that these devices can not receive the transmissions of the device lc. A bidirectional data communication 7 between the devices lc and la or lc and lb is therefore not feasible.

As a result, a system 11 according to the invention can be formed with the devices 1a and 1b, but not with the devices 1a and / or 1b and 1c. FIGS. 3 to 6 show examples of symbols which can be displayed on a device 1 according to the invention and which indicate a given current status of a device 1 participating in a construction of a technical system according to the invention. FIG. 3 shows in particular an example of a first symbol 13 for the status of the device 1, in which the device 1 informs other devices 1 of the willingness to build up a technical system 11 according to the invention. FIG. 4 shows, in particular, an example of a second symbol 14 for the status of the device 1, in which it receives from another device 1 according to the invention the signal indicating its readiness to form a technical system 11 according to the invention.

FIG. 5 shows, in particular, an example of a third symbol 15 composed of the first symbol 13 and the second symbol 14 for the status of the device 1, in which it is currently establishing a connection for a bidirectional data communication 7 with at least one other other according to the invention Device 1 to form a technical system 11 according to the invention with this at least one single device 1 according to the invention. FIG. 6 shows in particular an example of a fourth symbol 17 for the status of the device 1 composed of the first symbol 13, second symbol 14 and folded first symbol 16 in which there is a connection for bidirectional data communication 7 with at least one other other device according to the invention 1 and a technical system 11 according to the invention has constructed with this at least one single device 1 according to the invention.

Figures 7 and 8 show a detail of an inventive technical system 11 with devices 1 according to the invention in a first (Figure 7) and second (Figure 8) situation. The technical system 11 in FIGS. 7 and 8 is formed with devices 1 according to the invention, some of which are designated by the reference symbols 1 a, 1 b, 1 c, 1 d, 1e, 1f, 1g, 1h and 1i. The technical systems 11 of FIGS. 7 and 8 are identical, so that devices 1 and / or the same name are the same devices 1, respectively. FIGS. 7 and 8 show a multiplicity of devices according to the invention

I for the inventive technical system thus formed

II shown. In the minimum case, only two devices 1 according to the invention can be used for this purpose. Regardless of how many devices 1 belong to the technical system 11 according to the invention, two appliances 5 which are synchronized with each other and which are synchronized with each other can also have a mechanical link 10 (FIG. 15) with a selectable and / or selected folding angle between them be mechanically connected.

The technical system 11 according to FIGS. 7 and 8 has a plurality of devices 1 synchronized with one another in such a way that for a device 1 synchronized here with the device 1, an overall touch screen 9 consisting of the touch screens of the individual others, here the devices lb to Ii, synchronized with each other devices 1 is formed such that at least parts of a Image representation of one, here the device la, device 1 controlled by the one, here device la, device 1 on the touch screens selected synchronized with each other, here devices lb to Ii, devices 1 as originally functional, here as on the device la, representable are.

According to the representations of FIGS. 7 and 8, the respective devices 1 according to the invention are furthermore arranged in a matrix structure with exact rows and columns, as the respective figure detail 18 shows. Such an orientation is not necessarily necessary. Individual matrix positions can not be occupied by devices 1 or they can be freely distributed. Depending on the arrangement of the devices 1 with each other in their mutual synchronization then image sections that are assigned to an unoccupied position, be hidden or simply be assigned to the nearest device 1. Overall, many application structures are conceivable here and can be solved by appropriate arrangements of the relevant devices 1 with each other.

In the present exemplary embodiment according to FIGS. 7 and 8, the exact matrix structure is selected. In this case, in FIG. 7, the device 1a displays on its touch-sensitive touch screen a touch-sensitive image representation. This image representation is relatively small due to the fact that this image representation is shown only on the one small touch screen.

The fact that the device 1 is part of the inventive system 11 and that the individual touch screens of the individual devices, for example la to li, form an overall touch screen 9, for example for the one device la, can be achieved by appropriate contact with the touch screen (s) of the devices 1a to Ii, for example, rearranging the image display of the device 1a beyond the touch screen of the device 1a and so on the touch screens the devices la to Ii distributed with appropriate magnification be displayed again (Figure 8). All other types of image manipulation are also conceivable, such as turning and so on. It is also possible to start, for example, applications by, for example, double-tapping on specific areas of the image representation for, for example, receiving additional information. Furthermore, only individual display parts or display areas of an original image representation can be redrawn to other touch screens of the system.

FIG. 9 shows a possible general flow diagram relating to a basic mode of operation of a device 1 according to the invention. At a start time, the device 1 is switched to either an active or a passive mode with regard to the readiness to form a system 11 according to the invention.

In the active mode, a device 1 emits a signal indicating the readiness to form a technical system 11 with other devices 1. In addition, the device 1 tries to detect such a signal from other devices 1 which are also ready to form the technical system 11. The devices 1 switched into the passive mode try only to recognize a signal indicating the readiness to form a technical system 11 and sent by other devices 1. A device 1, which is connected to neither said active nor in said passive mode, is not available for the formation of the technical system 11.

If a said signal is detected by a device 1 which is in said active or passive mode, the relevant device 1 starts the preparation for the corresponding synchronization with the respectively relevant other devices. In preparation for synchronization, corresponding information needed by the respective devices to ensure the functioning of the technical device 11 is exchanged.

After completion of the preparation of the synchronization is synchronized with the effect that at the end of the synchronization, a technical system 11 is present, in which each of the formed technical system 11 associated devices 1 represents images, each for each device 1 due to distributed Picture representations of the touch screens 2 of the synchronized for this purpose devices 1 of originally un-distributed image representations.

At the same time, the successful synchronization can be checked and the output of image representations only released if the synchronization was successful. If the synchronization was successful and a split image is to be output, the split image is output. Otherwise, everything is left as it is. Subsequently, it is checked whether the passive mode of the relevant device 1 is off. If the passive mode is not sufficient, the relevant device 1 jumps back into the point of carrying out the recognition of devices 1 ready to form the technical system 11. If the passive mode is off, it will check if the active mode is off. If the active mode is not off, the device 1 in question jumps back into the point of carrying out the output of the signal indicating the readiness for forming the technical system 11. If the active mode is also off, the relevant device 1 is only available again for forming a technical system 11 when it is switched to the active or passive mode. If an unsuccessful synchronization is detected when checking a successful synchronization, an entry is made into the point of checking whether the passive mode is switched off.

In parallel, both the entire active and in the entire passive mode, the accuracy can be checked and monitored, with appropriate error corrective action can be initiated in an error. If no troubleshooting is initiated, the relevant device 1 for the formation of a technical system 11 can no longer be made available until the error is corrected. If a relevant device 1 in the state of recognition for the formation of the technical system 11 ready device 1, takes place, as the figure 10 shows, first a check, whether a ready for the formation of the technical system 11 ready or newly arrived ready device 1 recognized becomes. If this is not the case, an entry is made into the point of checking whether successful synchronization is present. If such a device 1 is detected, the external readiness signal, which signals a foreign willingness to form the technical system 11 and signals its own readiness, can be assigned to the sender when the foreign standby signal is received. This is followed by outputting the own acknowledgment signal which signals the receipt of the foreign standby signal and which can be assigned to the sender. If the recognition of ready devices 1 is based on the fact that a so-called foreign device 1 responds to its own ready signal with an acknowledgment signal, the acceptance of the foreign acknowledgment signal takes place upon arrival of the foreign acknowledgment signal. In FIG. 11, the operating mode of preparing the synchronization is shown by way of example. In this mode of operation, a request for and receipt of manually entered information about an optional concrete Master or slave arrangement. In the case of a specific slave allocation, further request and receipt of information to be entered manually via an optionally specific matrix / image segment assignment takes place after receipt of at least one single acknowledgment signal. Subsequently, a check is made interactively with the knowledge of the sender of received acknowledgment signals, the assignments of the acknowledgment sender and the own assignment to the presence of only a single master assignment. Finally, a request with knowledge of the sender of received acknowledgment signals takes place the matrix image segment assignments of the acknowledgment signal sender with its own master assignment. In the Synchronize operating mode, the interactive synchronization of the touch screens 2 of the confirmation signals issuing devices 1 to a single overall touch screen 9 for the device 1 with master assignment depending on the concrete master, the concrete slave and the concrete matrix image segment. Assignments.

When preparing to synchronize can be checked in parallel for errors, with a reporting an error with or without correction option and with or without change to a predetermined working state at least when there is a detection of the presence of more than two master assignments.

In the case of a separate master assignment, a request with knowledge of the sender of received acknowledgment signals from image display parameters of the touch screens 2 of the devices 1 associated with the acknowledgment signal sender takes place during preparation of the synchronization.

In addition, in the case of a separate master assignment in the course of the main method, an image to be displayed is split at least in part onto the individual touch screens 2 of the extended overall touch screen 9. In this case, the image display is taken into account. Parameters of the respective touch screens 2 of the respective devices 1 of the extended total touch screen 9 when splitting a total image to be displayed on the individual touch screens 2 of the extended total touch screen 9th

The respective devices 1 described above are equipped with a computer program product comprising a computer program formed by program code means for selectively implementing the method according to any one of claims 13 to 21 when the computer program is executed on the device 1.

Figure 13 shows concretely a device 1 according to the invention in an oblong horizontal position with a known frequent image representation, which essentially consists of a lower text input part by means of a so-called soft keyboard and an upper text display part. As can be seen on a symbol 17 in a topmost image line, the device 1 shown is in synchronization with another inventive device 1, not shown in detail in FIG. 13, with which it forms a technical system 11 according to the invention. FIG. 14 shows the technical system 11 according to the invention, which is addressed with reference to FIG. In this case, the image display area of the entire original image display area which is responsible for the text input, for example with corresponding finger touches, which is not shown per se and only indicated by an arrow cross 19, has already been pushed halfway out of the touch screen 2 of the original device 1a and into the touch screen 2 of the device still involved in the technical system 11 lb pushed. Arrow 19 indicates that said image display area can be momentarily moved in all directions. The technical system 11 of FIG. 14 can be seen in FIG. 15, wherein the image display area responsible for the text input has already been completely shifted to the touch screen 2 of the second device 1b, on which it can be used just as well as on the original device 1a the device 1 is operable.

As FIG. 15 likewise shows, the image display area responsible for the text input has been fitted on the touchscreen 2 of the device 1b and has been mounted at maximum size. Likewise, the text display part responsible for the text display has been enlarged on the original device 1a. This has been indicated in the figure 15 each with Aufziehpfeilen 20.

In sum, both an enlarged text display part and an enlarged soft keyboard are available.

Many other display options are also conceivable here.
