Title: Method for generating graphic representation in a mobile terminal

Description:
The invention relates to the generation of graphics which may be a part of a messaging between mobile communication terminals. Particularly, the invention relates to a method of generating of a compound graphic comprising a plurality of illustrating graphical elements, wherein the illustrating graphical elements can be selected by the user to enable the user to generate an individual compound graphic. Therefore, the illustrating graphical elements are stored in a graphical element library.  
      Mobile communication terminals, like mobile phones, offer the possibility to transmit messages between them. The usage of messages grew rapidly over the last years. The global system for mobile communications (GSM) standard for mobile communication defines a messaging service known as short message service (SMS). Further standards for mobile communication define related services. Formerly, only text messages based on the short message service (SMS) were available. The standard definition of the text messages was enhanced in order to provide transmission of also graphical illustrations. These graphical illustrations may be included in the text messages or appended to the text messages. Modern mobile phones enable this enhancing feature and allow to transmit graphics as a part of the messaging between communication terminals.  
      Up to now, graphics to be integrated, included or appended to messages are stored within a graphic library included in the mobile terminal. Usually, these graphics are pre-defined and not be modifiable since the input means of mobile terminal devices are strongly limited, e.g. mobile phones normally provide an ITU-T (international telecommunication union-telephone) keypad. It is obviously, that such an ITU-T keypad is not useful for designing new graphics. Of course, graphic editors which are pixel orientated are available for mobile terminal devices but such graphic editors lack of acceptable deployment.  
      Therefore, new graphics are normally generated on an external device like a personal computer (PC) and transmitted via special dedicated services to mobile phones where these graphics may be stored for further usage. This method is not flexible enough for users which wish to include individual graphics to their messages.  
      A smart method for generating compound graphics may be provided advantageously to especially users of mobile terminals of limited inputting components to enable the users to design individual graphics in a fast and appropriate way.  
      An object of the invention is to provide a method for generating compound graphics. These compound graphics consist of illustrating graphical elements which can be selected and arranged by a user in an easy and fast way.  
      A further object of the invention is to provide a mobile terminal which allows a user to operate an embodiment of the method for generating compound graphics according to the present invention.  
      The objects of the present invention are solved by the accompanying independent claims  1  and  16 . Embodiments of the present invention are the subject of dependent claims.  
      According to an embodiment of the present invention a method for generating a compound graphic is provided. The compound graphic comprises a plurality of illustrating graphical elements. The illustrating graphical elements are stored in a graphical element library. In a first step of the method an initial compound graphic may be displayed. The initial compound graphic may comprise selected or pre-selected illustrating graphical elements. In a following step a modification request may be inputted. The request may designate a certain illustrating graphical element of the displayed compound graphic and defines the modification thereof. The modification may be performed according to the modification request. Thereafter, the resulting modified compound graphic containing said amended or updated or modified element is displayed. The selected or pre-selected graphical elements of the initial compound graphic may be retrieved from a library or may be produced from scratch.  
      It may be noted that the method according to an embodiment of the present invention may be implemented in a graphic editor. The graphic editor may be a function or a feature of a mobile terminal. Preferably, the mobile terminal may be a mobile communication terminal and the graphic generated by the graphic editor may be appended or included in a text message. The text message may be communicated between mobile communication terminals via a mobile communication network, like global system for mobile communication (GSM), universal mobile telecommunication system (UMTS) and the like. The composing of a compound graphic consisting of a plurality of illustrating graphical elements may be preferably used in combination with terminals having limited inputting means, like a keypad comprising a limited number of keys.  
      The inputting of a modification request, the modifying and the displaying of the resulting compound graphics may be repeated until a desired resulting compound graphic is displayed.  
      The modifying of an illustrating graphical element may be a replacing of a displayed illustrating graphical element. The modifying of an illustrating graphical element may be also a removing of a displayed illustrating element. And the modifying of an illustrating graphical element may be an adding of a not yet displayed illustrating graphical element.  
      The modifying of an illustrating graphical element may involve a retrieving of an illustrating graphical element from the graphical element library.  
      The graphical element library and the compound graphics may described a certain comprehensive graphical subject. Accordingly, the illustrating graphical elements may represent graphical sub-subjects of the compound graphic or graphical element library, respectively. Preferably, several illustrating graphical elements may be illustrating graphical elements of the same sub-subject.  
      The compound graphic comprises at most one illustrating graphical element of each graphical sub-subject. The modification of an illustrating graphical element means that another illustrating graphical element of the same graphical sub-subject is composed to the compound graphics and replaces the before displayed illustrating graphical element.  
      The composition of a compound graphic may be described exemplary in view of a graphical subject “landscape”. Graphical sub-subjects may be “foreground”, “background” and “sky”.  
      Each graphical sub-subject may comprise several illustrating graphical elements. The composition of the illustrating graphical elements of the graphical sub-subjects may lead to a compound graphic illustrating a “landscape” according to the given graphical subject.  
      Illustrating graphical elements of the graphical sub-subject “foreground” may be illustrating graphical elements showing: “broad-leaved trees”, “coniferous tree”, skyscrapers, “animals” like “horses”, “cows”, “persons”, “aliens”, “cars” or “lake”. Illustrating graphical elements of the graphical sub-subject “background” may be illustrating graphical elements showing: “mountains”, “hills”, “misty landscape” or “city”. Illustrating graphical elements of the graphical sub-subject “background” may be illustrating graphical elements showing: “sun”, “cloudy sky”, “clouds of a storm”, “clouds in the sunset”, “dusky sky”, “fine weather” or “starry sky”.  
      The number of illustrating graphical elements as well as the number of graphical sub-subjects according to a graphical subject of the compound graphic may be not limited.  
      The displaying of a compound graphic may comprise a composing of the illustrating graphical elements to the displayed compound graphic. Information like position of each illustrating graphical element within the compound graphic and/or overlaying of the illustrating graphical elements with reference to each other may be necessary. The illustrating graphical elements may comprise this information such that the positioning and the sequencing may be pre-defined.  
      The designation which may be comprised by the modification request may designate the graphical sub-subject. Therefore, the modification request may be a replacing of the illustrating graphical element of the designated graphical sub-subject with another illustrating graphical element of the same graphical sub-subject. A modification request designating a graphical sub-subject of the compound graphic may allow to modify the compound graphic even if only a limited number of means for inputting are available. The number of graphical sub-subjects of a compound graphic is lower than the total number of illustrating graphical elements provided for composing the compound graphic. Therefore for example, even a keypad of a mobile phone (ITU-T keypad) may be employed for inputting the modification requests in an adequate and user-friendly way.  
      The resulting compound graphic may be stored. The storing of the compound graphic may allow to employ the compound graphic for further operations or to modify the stored compound graphic at a later moment. Further, the resulting compound graphic may be included or appended to a text message. This feature may be interesting in combination with mobile phones able to transmit messages comprising graphics.  
      A menu may be offered to a user for selecting and inputting modification requests. The menu may be a text menu or a menu presenting graphical items for selecting. The menu may be operated by soft keys or function keys. The function of these keys may be described and defined by the menu items.  
      A keyboard or a keypad may be used for selecting and inputting modification requests, wherein keys of the keyboard or keypad may have assigned certain pre-defined modification requests.  
      Selecting a key may toggle between illustrating graphical elements of a selection of illustrating graphical elements. The respective illustrating graphical elements may be listed in a pre-defined sequence. Toggling of the illustrating graphical elements means that a displayed illustrating graphical element is removed from the compound graphic and a new illustrating graphical elements is placed instead into the compound graphic. The new illustrating graphical element may preferably be the illustrating graphical element following the replaced illustrating graphical element in the pre-defined sequence.  
      Further, the sequence of illustrating graphical elements may be represented by illustrating graphical elements of one graphical sub-subject.  
      At least one illustrating graphical element may be an animated illustrating graphical element.  
      According to another embodiment of the invention a software tool for generating a compound graphic comprising a plurality of illustrating graphical elements is provided. The software tool comprises program potions for carrying out the operations of the aforementioned for generating a compound graphic comprising a plurality of illustrating graphical elements when the software tool is implemented in a computer program and/or executed on a computer, a processing device or a mobile terminal.  
      According to another embodiment of the invention a computer program for generating a compound graphic comprising a plurality of illustrating graphical elements is provided. The computer program comprises program potions for carrying out the operations of the aforementioned methods for generating a compound graphic comprising a plurality of illustrating graphical elements when the software tool is implemented in a computer program and/or executed on a computer, a processing device or a mobile terminal.  
      According to another embodiment of the invention a computer program product is provided which comprises program code portions stored on a computer readable medium for carrying out the aforementioned methods for generating a compound graphic comprising a plurality of illustrating graphical elements when said program product is executed on a computer, a processing device or a mobile terminal.  
      According to a further embodiment of the invention a mobile terminal for generating a compound graphic comprising a plurality of illustrating graphical elements is provided. A graphical element library may comprise the illustrating graphical elements. The mobile terminal according to an embodiment of the present invention may comprise storing means for storing the illustrating graphical elements or the graphical element library, respectively and pre-selecting means for pre-selecting a compound graphic comprising illustrating graphical elements. The pre-selecting means may be a pre-defined selection of illustrating graphical elements which composition results in a compound graphic. Further, the mobile terminal according to an embodiment of the present invention may comprise displaying means for displaying a compound graphic composed of several illustrating graphical elements, inputting means for inputting modification requests by a user to control the modification of the compound graphic and modifying means for modifying an illustrating graphical element of the compound graphic according to the modification request.  
      A modification request may comprise a designation of the illustrating graphical elements which may be modified according to the modification request. The modifying means may comprise a composing of the illustrating graphical elements wherein a modifying operation may comprise a removing of an illustrating graphical element, an adding of a further illustrating graphical element or a replacing of a displayed illustrating graphical element with another illustrating graphical element.  
      The mobile terminal may be a mobile communication terminal able to communicate via a mobile communication network. The resulting compound graphic may be appended to or included in a text message which may be communicated between mobile communication terminals via a mobile communication network, like global system for mobile communication (GSM), universals mobile telecommunication system (UMTS) or the like.  
      The graphical element library and the compound graphic may describes a certain comprehensive graphical subject, respectively. Accordingly, the illustrating graphical elements may represent graphical sub-subjects of the compound graphics or graphical element library, respectively. Preferably, several illustrating graphical elements may be illustrating graphical elements of the same graphical sub-subjects.  
      The compound graphic comprises at most one illustrating graphical element of each graphical sub-subject. The modification of an illustrating graphical element means that another illustrating graphical element of the same sub-subject is composed to the compound graphics and replaces the before displayed illustrating graphical element. It may be noted that a blank illustrating graphical element may be a legal member of a graphical sub-subject.  
      The modification of a compound graphic may comprise a retrieving of illustrating graphical elements from the graphical element library. Therefore, the mobile terminal may comprise retrieving means for retrieving an illustrating graphical element from the graphical element library.  
      The mobile terminal according to an embodiment of the invention may comprise storing means for storing the resulting compound graphic. The storing of the compound graphics may allow to employ the compound graphic for further operations or to modify the stored compound graphic at a later moment. Further, the resulting compound graphic may be included or appended to a text message. This feature may be interesting in combination with mobile phones able to transmit messages comprising graphics. Accordingly, the mobile terminal may comprise means for including and/or appending compound graphics to a text message.  
      A menu may be offered to a user for selecting and inputting modification requests. The menu may be a text menu or a menu presenting graphical items for selecting. The menu may be operated by soft keys or function keys. The function of these keys may be described and defined by the menu items.  
      A keyboard or a keypad may be used for selecting and inputting modification requests, wherein keys of the keyboard or keypad may have assigned certain pre-defined modification requests. The keypad may be an ITU-T keypad of a mobile communication terminal or a QWERTY keyboard (typewriter keyboard). A pre-definition of the modification requests and the assignment of the modification requests to certain pre-defined keys of the keypad may be especially preferable in case of usage of an ITU-T keypad as inputting means.  
      Selecting a key may toggle between illustrating graphical elements of a selection of illustrating graphical elements. The respective illustrating graphical elements may be listed in a pre-defined sequence. Toggling of the illustrating graphical elements means that a displayed illustrating graphical element is removed from the compound graphics and a new illustrating graphical element is placed instead into the compound graphic. The new illustrating graphical element may preferably be an illustrating graphical element following the replaced illustrating graphical element in the pre-defined sequence.  
      Further, the sequence of illustrating graphical elements may be represented by illustrating graphical elements of one graphical sub-subject.  
      At least one illustrating graphical element may be an animated illustrating graphical element.  
      The graphical element library may be stored in the mobile terminal. The graphical element library may be exchangeable. An exchange of a graphical element library may be an exchange of at least one illustrating graphical element or of the whole graphical element library.

      The compound graphic is composed of several illustrating graphical elements. The illustrating graphical elements may be retrieved from a graphical element library. Preferably, the illustrating graphical elements refer to a common graphical subject.  
      In an embodiment according to the present invention the method is described with regard to “smileys”. Smileys or emoticons are well known and highly appreciated especially among young users, respectively, to append signs to text messages in order to express a broad variety of emotions. Normally, smileys or emoticons are put together of less ASCII signs, for example the shortcut “:-)” express a smiling face or the shortcut “:-(” express a sad face. The possibility to include or append graphics to text messages, especially in view of messages transmitted via mobile communication networks, makes it possible to replace the cryptic shortcuts with real graphic icons which can be understood easier, even to users not firm to the cryptic emoticons shortcuts. A smiling face may be expressed by “ ” instead of “:-)” or a sad face may be expressed by “ ” instead of “:-(”.  
      Such emoticons or related graphics but also graphics of further different graphical subjects may be provided by storing the graphics in a library for retrieving and utilising by the user. Such a library containing a limited number of unmodifiable graphics may not cover the wishes of users to use individual and situation adapted graphics. This disadvantage of static graphic libraries is solved by the employment of a graphical element library containing illustrating graphical elements which are adapted to a comprehensive graphical subject.  
       FIG. 1  shows an exemplary compound graphic comprising several illustrating graphical elements and the illustrating graphical elements themselves. The comprehensive graphical subject according to an embodiment of the present invention may be the visualisation of different individualised emoticons or smileys, respectively. Accordingly,  FIG. 1  shows a possible smiley C 1  as compound graphic.  
      This smiley C 1  is composed of several illustrating graphical elements. The element E 1  represents the shape and the filling colour of the head. The illustrating graphical element E 1  may be one of several elements available for shape and filling colour of the head. The illustrating graphical element E 2  relates to the design and look of the eyes. Herein the illustrating graphical element E 2  may represent sunglasses, but also other designs and looks of the eyes of the smiley C 1  may be possible. Furthermore, the illustrating graphical element E 3  relates to the mouth of the smiley C 1 . Herein the illustrating graphical element E 3  illustrates a laughing opened mouth. Additionally, the illustrating graphical elements E 4  and E 5  represent a cap and hairs, respectively.  
      The presented compound graphic C 1 , namely the smiley C 1 , composed of the illustrating graphical elements E 1 , E 2 , E 3 , E 4  and E 5  may not be limiting. The  FIG. 1  shall introduce to the possibilities of a graphic editing method according to an embodiment of the present invention. The graphical element library may be a certain comprehensive graphical subject or theme, respectively, and therefore the illustrating graphical elements may relate to different graphical sub-subjects. Preferably, a plurality of illustrating graphical elements may relate to the same graphical sub-subject so that the user may compose individually the illustrating graphical elements to a compound graphic. Following figures will further enlighten the method and extend the example according to  FIG. 1 .  
      In the following, the method for generating a compound graphic according to an embodiment of the invention may be described in detail. The compound graphic may be composed of a plurality of illustrating graphical elements.  
       FIG. 2  illustrates schematically the operative steps of the method for generating compound graphics according to an embodiment of the invention.  
      In a step S 100 , the generation of a compound graphic is started.  
      In a step S 101 , a default compound graphic is displayed. The default compound graphic is composed of pre-selected illustrating graphical elements. The composing of the illustrating graphical elements to a compound graphic may comprise information on the position and on the overlaying of the illustrating graphical elements. The illustrating graphical elements may comprised information of the position at which they may have to be displayed. Further, the sequence of displaying or composing the illustrating graphical elements may be important in case that illustrating graphical elements may cover parts of other displayed illustrating graphical elements. Therefore, the composing may comprise information if the illustrating graphical element may be a background illustrating graphical element, a foreground illustrating graphical element. The composing may comprise a layer information in order to arrange the illustrating graphical elements in an appropriate sequence.  
      In a step S 102 , a user request may define a modification operation of the displayed compound graphic. The modification request may relate to exchanging, adding or replacing of an illustrating graphical element.  
      A user request may be defined by selecting a certain key of a keyboard or a keypad, respectively. The keys may be assigned to certain pre-defined modification operations. Preferably, the keys may be assigned to the modification of illustrating graphical elements of a graphical sub-subject of the comprehensive graphical subject of the compound graphic, for example with regard to  FIG. 1  to the modification of the head shape, eyes, mouth and the like. The assignment of the keys to certain pre-defined modification operations may be presented by a key assignment table. Such a key assignment table may be adapted to the comprehensive graphical subject or theme of the graphical element library and its graphical sub-subjects represented by the illustrating graphical elements of the library. Furthermore, this assignment method for initiating modification operations may enable to assign a plurality of illustrating graphical elements to a single key, wherein the selecting of the respective key may toggle the displaying between the different illustrating graphical elements designating the same graphical sub-subject.  
      Further, a user request may be initiated by selecting of a menu item of a menu. Such a menu may be a text menu or a graphical menu which may be operated by soft keys or function keys, respectively. Such a menu may allow to give a pre-view of the illustrating graphical element which may be effected by the modification operation or may show an illustrating graphical element which may replace a displayed illustrating graphical element.  
      The user request may also be a general user request, like storing the current displayed compound graphic, passing over the displayed compound graphic for further operations (transmitting via a mobile communication network, appending to a text message), leaving the graphic generation or the like.  
      In a step S 103 , in case of a modifying request the operation sequence is continued with step S 104  Otherwise the operation sequence is continued with step S 106 .  
      In a step S 104 , the user modification request defines a modification operation of the displayed compound graphic. According to the modification operation it may be necessary to retrieve an illustrating graphical element from the graphical element library.  
      The modification operation of the displayed compound may involve a replacing operation of an illustrating graphical element of the displayed compound graphic with an illustrating graphical element which may be retrieved from the graphical element library according to the modification request of the user. The modification operation may also involve an adding operation of an illustrating graphical element which may be retrieved from the graphical element library according to the modification request of the user.  
      In a step S 105 , the modified compound graphic is displayed. The displaying of the modified compound graphic allows the user to assess the current composing of the illustrating graphical elements which result in the compound graphic.  
      The displaying of the compound graphic may include a composing of the illustrating graphical elements to a compound graphic. The composing may comprise information on the position and on the overlaying of the illustrating graphical elements. Therefore, the illustrating graphical elements may comprise information of their positions within a compound graphic and information of their layer arranging in order to compose the compound graphic of a correct illustrating graphical element sequence.  
      Further, the sequence is continued with step S 102  and modification of the compound graphic may be initiated by further user requests.  
      In a step S 106 , in case of an exit request the sequence may be continued with step S 107 .  
      Otherwise the sequence may be continued with step S 102  for operating further following user requests.  
      In a step S 107 , the finishing of the compound graphic generation may involve further operations like storing the current displayed compound graphic, passing over the displayed compound graphic for further operations (transmitting via a mobile communication network, appending to a text message), leaving the graphic generation or the like.  
      The above described generation of a compound graphic consisting of several illustrating graphical elements may allow to generate a high number of compound graphics out of a limited number of single illustrating graphical elements.  
      The following figures will describe a possible structure of a graphical element library containing illustrating graphical elements according to an embodiment of the invention. The logical structure of the graphical element library may be based on the structuring corresponding to the graphical sub-subject of the graphical subject of the graphical element library.  
       FIG. 3  illustrates schematically a possible logical structure of a graphical element library with respect to an embodiment of the invention. The graphical element library L 1  may contain several element tables T 1 , T 2 , T 3  and T 4 . These element tables may represent an arbitrary number of element tables contained in the graphical element library L 1 . The element tables may represent different graphical sub-subject.  
      Each element table T 1 , T 2 , T 3  or T 4  may contain an arbitrary number of illustrating graphical elements. Herein, the element table T 1  may contain the illustrating graphical elements  1 . 1 ,  1 . 2  and  1 . 3 , the element table T 2  may contain the illustrating graphical elements  2 . 1 ,  2 . 2  and  2 . 3 , the element table T 3  may contain the illustrating graphical elements  3 . 1 ,  3 . 2  and  3 . 3  and the element table T 4  may contain the illustrating graphical elements  4 . 1 ,  4 . 2  and  4 . 3 . The illustrating graphical elements of each element table T 1 , T 2 , T 3  or T 4  may be illustrating graphical elements according to the graphical sub-subject of the element table.  
      This logical structure of the graphical element library may enable the user to modify a compound graphic consisting of a selection of the illustrating graphical elements in a fast and easy manner while a broad variety of resulting compound graphics may be achieved.  
      For example, the selected or pre-selected compound graphic, see  FIG. 1  step S 101 , may be composed of one illustrating graphical elements of each element table of the graphical element library L 1 . These illustrating graphical elements may be the illustrating graphical elements  1 . 1 ,  2 . 1 ,  3 . 1  and  4 . 1 .  
      A modification request of a user may be a request instructing to modify an illustrating graphical element of a certain graphical sub-subject. For example, the illustrating graphical element  2 . 1  may be exchanged against another illustrating graphical element. The illustrating graphical element  2 . 1  may be only exchanged against another matching illustrating graphical element, i.e. an illustrating graphical element of the same graphical sub-subject or an illustrating graphical element of element table T 2  which contains the displayed illustrating graphical element  2 . 1 . All other displayed illustrating graphical elements may remain in the compound graphic unmodified. A modification request may “toggle” within the element table T 2  for selecting an illustrating graphical element for exchanging the displayed illustrating graphical element  2 . 1 . “Toggling” means that the next illustrating graphical element of the element table T 2  may be employed to modify the display compound graphic, e.g. the illustrating graphical element  2 . 2 . If illustrating graphical element  2 . 2  is displayed and a modification request instructs to exchange the display illustrating graphical element  2 . 2  illustrating graphical element  2 . 3  may be used, i.e. the illustrating graphical element with the higher number herein. If no following illustrating graphical element is available within the respective element table the first illustrating graphical element may be employed for modification and be displayed again.  
      In the following an embodiment of a part of a graphical element library may be presented. The graphical subject of the exemplary graphical element library may be “smileys”. It shall be understood that the represented number, arrangement and sequence of the illustrating graphical elements is only exemplary and not limiting. Further illustrating graphical elements may be possible and even the graphical subject of the graphical element library is not limited to the presented graphical subject “smiley”.  
       FIG. 4   a  shows exemplary a plurality of illustrating graphical elements relating to the graphical sub-subject “head shapes” corresponding to a comprehensive graphical element library of the graphical subject “smiley”. Three different illustrating graphical elements E 0 . 1 , E 0 . 2  and E 0 . 3  are presented representing different shapes of “heads”. According to the above described “toggling” between the illustrating graphical elements a modification request may follow the depicted arrows S 20 , S 21  and S 22 . That means that in case of a displayed illustrating graphical element E 0 . 1  the illustrating graphical element E 0 . 2  may be displayed after modification of the compound graphic. In case of a displayed illustrating graphical element E 0 . 2  the illustrating graphical element E 0 . 3  may be displayed after modification of the compound graphic. And in case of a displayed illustrating graphical element E 0 . 3  the illustrating graphical element E 0 . 1  may be displayed after modification of the compound graphic.  
      Further illustrating graphical elements may be possible, for example head shapes of different eccentricity, as also another sequence of the illustrating graphical elements.  
       FIG. 4   b  shows exemplary a plurality of illustrating graphical elements relating to the graphical sub-subject “mouths” corresponding to a comprehensive graphical element library of the graphical subject “smiley”. The illustrating graphical elements E 1 . 1 , E 1 . 2 , E 1 . 3 , E 1 . 4 , E 1 . 5 , E 1 . 6  and E 1 . 7  represent different shapes of “mouths”. A toggling between the different illustrating graphical elements may follow the depicted arrows S 30 , S 31 , S 32 , S 33 , S 34 , S 35  and S 36 . The displaying of the illustrating graphical element within the compound graphic controlled by user requests may follow the sequence illustrated by the arrows.

The composition of these illustrating graphical elements leads to the shown compound graphic  17 .  
      In a step S 17  the user may further request to modify the displayed illustrating graphical element of the graphical sub-subject designed “head” of compound graphic  17 . Therefore, the user may select the key “1” of the keypad or keyboard, respectively. The modification request initiates a modification operation which replaces the illustrating graphical element E 0 . 1  with the next following illustrating graphical element E 0 . 2 . The resulting compound graphic  18  consists now of the illustrating graphical elements E 0 . 2 , E 1 . 3 , E 2 . 4 , E 3 . 3  and E 4 . 2 . The composition of these illustrating graphical elements leads to the shown compound graphic  18 .  
      The resulting compound graphic  18  may be obtained by selecting the key sequence: 2, 2, 3, 3, 3, 5, 4, 1 according to the definition of the modification operations described in the key assignment table above. All arbitrary permutations of this key sequence lead to the same resulting compound graphic  18  if the initial compound graphic  10  consists of the illustrating graphical elements E 0 . 1 , E 1 . 1 , E 2 . 1 , E 3 . 1  and E 4 . 1  and the sequence of the remaining displayed illustrating graphical elements is given like shown in the  FIGS. 4   a ,  4   b ,  4   c ,  4   d  and  4   e.    
      This method for generating a compound graphic allows a user to generate a total number of 3150 different compound graphics coming from summarised total  26  illustrating graphical elements (“head”: 3 elements, “mouth”: 7 elements, “eyes and glasses”: 6 elements, “hairs, hats and caps”: 5 elements and “nose”: 5 elements).  
      The access method of “toggling” between illustrating graphical elements of the sub-subjects allows a fast, easy and reasonable access to the high number of different compound graphics.  
      The “toggling” of the illustrating graphical elements structured into different graphical sub-subjects may be especially useful to be used for inputting modification requests by terminals having limited inputting components such as mobile terminal, for example mobile phones. Usually, mobile phones are equipped with ITU-T keypads with just a few added soft or functional keys. The “toggling” may provide an adequate user interface for composing a compound graphic like described above. The following table may present another possible embodiment for inputting modification requests.  
                                   key   modification operation                  1   toggle between basic smileys: smiling and sad face, some           more basic emoticons       2   toggle between circle, vertical ellipse and horizontal ellipse (the           magnitude/eccentricity can be influenced by the arrow keys).       3   invert black and white, some colours (if coloured a display is           available)       4   toggle eyes between smiling, crying, sleeping, twinkling,           wide open, . . .       5   toggle mouth between smiling, flat, sad, crying, open, tongue       6   toggle between no and different kinds of hairstyles and hats       7   toggle ears and noses between no, small, big, long, broad, . . .       8   toggle between no and different kind of animations (if e.g. MMS           (multimedia messaging service) is supported by the mobile phone)       9   space for more fancy features       0   toggle between simple, double (original - opposite) or            triple (smooth transition from original to opposite) smileys       *   toggle between simple, double or triple smileys (all of the same           occurrence)       #   same as above, but vice versa                  
 
      Extended inputting components like a QWERTY-keyboard (typewriter keyboard) may allow to use more request inputting keys in order to offer a user an extended request control of the of the compound graphic. All these functions can also be provided via a selection ons menu.  
      The above presented method for inputting user requests for modification operations may be transferred easily to other graphical subjects of the compound graphics if the graphical subjects of the respective compound graphic may be divided into different graphical sub-subjects each represented by several illustrating graphical elements.  
      Another user request inputting may be described in the following  FIGS. 6   a  and  6   b . The description of this embodiment according to the invention is illustrated with regard to an ITU-T keypad normally used for example in mobile phones.
