[0007] In the following, the present invention will be described in more detail with reference to the appended drawings, in which [0008] [0008]FIG. 1 shows a communication device of prior art, equipped with game facilities, seen from above, [0009] [0009]FIG. 2a shows a communication device according to a preferred embodiment of the invention in a partial explosion view, [0010] [0010]FIG. 2b shows the communication device according to the first preferred embodiment of the invention, shown in FIG. 2, in a second functional position, [0011] [0011]FIG. 3 shows a communication device according to a second advantageous embodiment of the invention, [0012] [0012]FIG. 4a shows, in a partial explosion view, a communication device according to a third advantageous embodiment of the invention, corresponding to the first functional position, [0013] [0013]FIG. 4b shows, in a partial explosion view, a communication device according to the third advantageous embodiment of the invention, corresponding to the second functional position, [0014] [0014]FIG. 5 shows, in a reduced block chart, a communication device according to the first advantageous embodiment of the invention, [0015] [0015]FIG. 6a shows a replacement cover for a communication device according to a fourth advantageous embodiment of the invention in a partial explosion view, [0016] [0016]FIGS. 6b to 6 e show examples of user interfaces implemented with the cover structure of FIG. 6a, and [0017] [0017]FIG. 7 shows, in a reduced cross-section, a communication device according to the fourth advantageous embodiment of the invention.
[0018] The appended FIG. 2a shows a communication device 1 complying with a preferred embodiment of the invention in a partial explosion view. It comprises e.g. a housing 2 and a first user interface Ul1, preferably provided with a keypad 3 and a display 4. In this advantageous embodiment, the communication device 1 also comprises a replacement cover 5 provided with a second user interface comprising at least a keypad 6. For ordinary telephone functions, the first housing 2 of the communication device 1 is used, its second part 2 a being preferably provided with a keypad 3 and a display 4 for a first user interface Ul1. In this functional position, the replacement cover 5 is detached. Thus, the user can, in a way known as such, for example select a telephone number, answer an incoming call, change the settings of the communication device, etc. The communication device 1 used can be e.g. a wireless communication device, such as a GSM mobile station, a communicator, a GPRS mobile station, a UMTS mobile station, etc., but also a cabled telecommunication terminal, such as a personal computer (PC), a PDA device, etc. Instead of or in addition to said keypad 3, the user interface Ul1 may also comprise other input means, such as a roll controller, a joystick, audio control means (e.g. a microphone, not shown in the appended drawings), etc., for entering text, commands, selections, and so on. The user interface may also comprise other audio means, such as a speaker and/or an earpiece (not shown). [0019] In a situation in which the user wishes to shift to the game functions, the following steps are taken in connection with this communication device according to an advantageous embodiment of the invention. The user selects the game function by means of the keypad 3, wherein the communication device 1 shifts to a second mode with the facility to play games. Information is preferably displayed on the display 4 that the communication device 1 has shifted to this second mode. After this, the user can preferably select which game he/she wants to play. The selected game can be stored in the memory means 9 of the communication device (FIG. 5), or the game can be e.g. downloaded from a communication network, such as the Internet network. If the game is downloaded from a communication network, a data transmission connection is set up from the communication device 1 to this communication network in a way known as such, preferably by means of mobile station functions 10. However, it is obvious that the game can be downloaded e.g. from a local area network, wherein the data transmission connection used can be e.g. a wireless infrared connection (e.g. IrDA), a wireless radio connection (Bluetooth, WLAN), or a cabled connection between e.g. a PC (not shown) and the communication device 1, or a modem connection to a telecommunication network. [0020] After selection of the game function and possible downloading of a game, the user places a replacement cover 5 onto the housing 2 of the communication device 1. This replacement cover 5 is equipped with at least a keypad 6, in which the size and layout of the keys is designed in such a way that it is easy to play games. However, in the layout of the keys of this keypad 6, one must also consider the layout of the keys in the keypad 3 of the communication device, because pressing the keys of the keypad 6 is detected in this communication device 1 according to an advantageous embodiment of the invention by means of keystrokes of the keys 3, as will be described below. [0021] After the replacement cover 5 has been installed, the user can start to play games. In the example of FIGS. 2a and 2 b, the keypad 6 cornprises four arrow keys 6 a, 6 b, 6 c, 6 d, as well as a first 6 e and a second selection key 6 f. In this preferred embodiment, the keys 6 a-6 f are advantageously placed as follows. The left arrow key 6 a is at the left edge in the keypad, which is logical in view of the function of this key. In a corresponding manner, the right arrow key 6 b is placed at the right edge, the up arrow key 6 c is placed slightly in the centre of the keypad 6, slightly above the left and the right arrow keys 6 a, 6 b, and the down arrow key 6 d is placed in the centre, slightly below the left and the right arrow keys 6 a, 6 b. The first and the second selection keys 6 e, 6 f are placed below the arrow keys 6 a-6 d. These keys 6 a-6 f are arranged to be movable in a direction substantially perpendicular to the main plane of the replacement cover 5. Thus, a keystroke will push down one of the keys in the keypad 3 of the communication device. Thus, the processor 11, or a possible keypad controller (not shown), in the communication device 1 will detect that a key has been pushed down. After this, it is determined which key was pushed down. The key information is transferred to the use of the running game program, wherein the game program will operate in a way required by the keystroke, e.g. move an object on the display. For example, the left arrow key 6 a is at least partly placed at the numeric key “4”0 of the keypad 3 (indicated with reference 3 d in FIG. 2a). Thus, pushing down the left arrow key 6 a will push down the numeric key “4”, which is detected in the communication device. Respectively, the right arrow key 6 b is placed at least partly at the numeric key “6” of the keypad 3 (indicated with reference 3 f in FIG. 2a), the up arrow key 6 c is placed at least partly at the numeric key “2” of the keypad 3 (3 b in FIG. 2a), and the down arrow key 6 d is placed at least partly at the numeric key “8” of the keypad 3 (3 f in FIG. 2a). The first selection key 6 e is placed at least partly at the “*” key 3 j, and the second selection key 6 f is placed at least partly at the “#” key 31. It is obvious that the present invention is not limited solely to the above-presented key arrangements, but when applying the invention, it is also possible to use other kinds of keypads 6 and combinations of the keypad keys 6 a-6 f and the keypad keys 3 a-3 l. [0022] The communication device 1 of the invention is preferably provided with a facility to answer an incoming call also when the communication device 1 is set in the game mode. Answering a call in the came mode can be preferably made by any key in the keypad 6, or a specific key can be reserved for this purpose, which is used as a key for answering an incoming call. In a corresponding manner, at the end of a call, the call can be terminated either with any key in the keypad 6 or with a specific key in the keypad 6. Furthermore, the answering function can be set by the user, wherein the user can select e.g. answering with any key or answering with a predetermined key or with a key selected by the user. [0023] The replacement cover 5 is preferably equipped with an opening, or the replacement cover 5 is arranged in another way to be at least partly transparent at the display 4 of the communication device. Thus, the visual information of the game can be seen through this replacement cover 5, wherein a separate display will not be needed in the replacement cover. [0024] The shift from the game mode back to the telephone mode can be made e.g. so that the user detaches the replacement cover 5 and, by means of the keypad 3, makes the shift from the game mode to the telephone mode in the settings of the communication device. It is obvious that the keypad 6 of the replacement cover 5 can also be used for terminating the game function, wherein the game function is terminated before detaching the replacement cover. [0025] The attachment and detachment of the replacement cover 5 can be arranged in many ways known as such. For example, the replacement cover 5 can be provided with flexible fixing means (not shown) which are supported by counterparts (not shown) arranged in the housing 2 when the replacement cover 5 is placed onto the housing 2. At the stage of detaching the replacement cover, these flexible fixing means are e.g. pressed down, when they are bent and the replacement cover 5 can be withdrawn from the top of the housing 2. In this context, reference is made to the applicant's international patent application WO 97/32423 which presents one such solution for providing a detachable replacement cover in an electronic device. [0026] The appended FIG. 3 shows a communication device 1 according to another advantageous embodiment of the invention. It comprises e.g. a housing 2 that can be opened, a two-part keyboard, a keypad 6, a display (not shown in FIG. 3), and a display 12. This communication device according to an advantageous embodiment, the first part of the keypad (not shown in FIG. 3) and the display are primarily used for ordinary telephone functions. The second part 3 b of the keypad and the display 12 are primarily used for performing data processing functions. The keyboard 6 and the display 12 are used e.g. in game functions for playing games. In FIG. 3, the communication device 1 is shown in an opened position, with the replacement cover installed, wherein the keyboard 6 and the display 12 are available. The replacement cover can also be detached, wherein the second part 3 b of the keyboard and the display 12 can be used normally. [0027] The keyboard 6 is provided, e.g. for game functions, with keys 6 a-6 f whose size is preferably larger than the size of keys in the keypad used in telephone functions. Furthermore, in the layout of these keys, it has been considered, when possible, that playing the games should be as easy as possible. In this advantageous embodiment of the invention, the game mode is selected for example in the following way. The user opens the housing of the device, if it is not already opened, and uses the keyboard 6 to select the game mode from the settings. After this, the keys 6 a-6 f are set to correspond to the key functions required in the game functions, such as the arrow keys 6 a-6 d and the selection keys 6 e, 6 f. Also, the selection of the game is preferably made at this stage, wherein the loading of the game is started, either from a memory or via a data transmission connection, as already presented above in this description. Preferably, it is also possible to answer calls by means of the keyboard 6, even though the game mode were active in the communication device 1. [0028] From the game function, it is possible to shift to the data processing functions preferably by changing the mode by means of the keyboard 6. Also the telephone functions can be used at this stage. If the housing 2 of the communication device is closed, the keypad 3 and the display 4 can be used for performing telephone functions. [0029] An advantage in this communication device according to the second advantageous embodiment of the invention is, for example, that the size of the display 12 can be arranged relatively large when compared with the size of the display 4, wherein the visual information of the games can be perceived better. [0030] The appended FIG. 4a shows, in a partial explosion view, a communication device 1 complying with a third advantageous embodiment of the invention, corresponding to the first mode, and FIG. 4b shows it corresponding to the second mode. In this embodiment, the keypad 3 is implemented as a so-called touch panel, in which an at least partly transparent touch-sensitive means 13 is placed onto the display 4. This touch-sensitive means 13 detects a pressing on it, wherein the controller (not shown) of the touch-sensitive means can determine the coordinates of the contact point and transmit this coordinate information to the processor 11 of the communication device (FIG. 5). After this, the processor 11 can retrieve the operations defined for the point in question. For example, the key functions can be implemented by means of the touch-sensitive means in such a way that a certain area on the surface of the touch-sensitive means corresponds to a certain keystroke. The transfer of the user's keystrokes to the touch-sensitive means can be implemented e.g. by providing the second part 2 a of the housing 2 of the communication device, with keys 3 a-3 l. When a key is pushed down, it goes down to the surface of the touch-sensitive means, wherein the contact is detected and the information is transmitted to the processor 11. For playing games, the second part 2 a can be replaced by a replacement cover 5 (FIG. 4b) provided with keys arranged for game functions, as presented in connection with the description of the first advantageous embodiment of the invention. Thus, as a result of the shift to the game mode, the strokes of the keys 6 a-6 f in the keyboard 6 of the replacement cover are interpreted differently than the strokes of the keys 3 a-3 l of the second part. The solution according to this embodiment has e.g. the advantage that the layout of the keys 6 a-6 f in the keyboard 6 of the auxiliary part can be implemented more freely, irrespective of the layout of the keys 3 a-3 l in the keypad 3 of the second part. Furthermore, the display area can be made larger, since the display 4 can be extended even to the keys of the keypad 3, even if, in the normal mode, a smaller area of the display 4 were used for display functions (indicated with reference 14 in FIGS. 4a and 4 b). [0031] [0031]FIG. 5 further shows a communication device 1 complying with the first preferred embodiment of the invention in a reduced block chart. It comprises, in addition to the functional parts presented above in this description, preferably at least audio means 15, such as an earpiece and/or a speaker and a microphone. [0032] Different alternatives for the user interface Ul1 of the communication device according to the invention can also be used for other purposes than playing games. For example, Internet browser programs have accelerator key functions for facilitating the browsing of home pages. For example, browsing forward, backward, stopping and moving to a default home page can be performed by selecting one single dialog box. In computers, an indicating device is normally used for this function, but in the communication device according to the present invention, this can be advantageously implemented so that for browsing in the Internet, the user changes a replacement cover 5 for the communication device, designed for this purpose and provided with separate keys e.g. for the above-mentioned browsing functions. Furthermore, different keyboard alternatives can also be implemented in calendar functions, calculator functions, PDA applications, or the like. [0033] The appended FIG. 6a shows, in a partial explosion view, a replacement cover structure to be used in connection with a communication device according to the fourth advantageous embodiment of the invention. In a corresponding manner, FIGS. 6b-6 e show different examples of user interfaces implemented with this structure. In this advantageous embodiment, the replacement cover 5 comprises a second part 5 a, a functional cover 5 b, a keypad 3, and a display 4. The second part 5 a is visible when the replacement cover 5 is installed in its position. The second part 5 a is provided with openings at the keys of the keypad 3. Furthermore, at the display 4, there is either an opening, or the second part 5 a is otherwise arranged to be at least partly transparent in this area, e.g. as a window implemented with transparent plastic. The keypad 3 is placed behind the second part 5 a. In a way known as such, it can be made of a flexible material and provided with the desired keys. Furthermore, this keypad is advantageously provided with symbols to indicate the function corresponding to each key. This keypad 3 is used to transmit the keystrokes to key elements 16 arranged in connection with the functional cover 5 b. When the corresponding key is being pressed down, these key elements 16 generate an electrical signal or turn a switch on/off, wherein information about the keystroke is transferred to the processor 11 or to another means for detecting keystrokes in the communication device, such as a keyboard controller (not shown), known as such. To transfer this keystroke information, the replacement cover 5 is provided with conductors 17 coupled to a connector 18. This connector 18 is arranged to be coupled to another electronics part 21 (FIG. 7), preferably connected to the first part 2 b of the housing 2 in the communication device. Thus, at the stage of installing the replacement cover 5, the user couples the connector 18 to a corresponding connection 22 in the electronics part (FIG. 7). The length of the conductors 17 can be selected so that, irrespective of the layout of the keypad 3 and the display 4, the connector 18 can be coupled to the corresponding connection 22 in the electronics part. By means of this connector 18, it is also possible to transfer information between the display 4 and the electronics part, or the replacement cover 5 can be provided with another connector for this purpose. If necessary, the connector 18 can also be used for indicating the layout of the user interface Ul1 of the replacement cover attached at the time, to the other electronics 21 of the communication device 1.This can be arranged e.g. so that specific pins of the connector 18 indicate the type of the replacement cover in question. For example, three pins can be used to provide eight different alternatives, if binary signals (0/1) are used in the pins. Thus, the type of the replacement cover corresponding to each binary combination is stored in the communication device 1. For the other pins, it is possible to define either a fixed use, such as the transfer of key signals or display signals, or the pins can be configured in a way known as such, wherein the configuration of the pins can also be indicated in the type of the replacement cover. [0034] The functional cover 5 b is preferably photoconductive, wherein it can be used for illuminating the keyboard 5 and for conducting light to desired points, such as to the display 4, from the front, from the side, or from behind. Thus, background light can be replaced by light conducted to the display by means of the cover. Through the functional cover 5 b, light can also be conducted to illuminate the keypad 3, to illuminate various figures, such as manufacturer logos, and to provide other light effects, such as stripes, in the communication device 1. These light effects can also be used for indicating e.g. an incoming call. Such a photoconductive functional cover 5 b can thus be used to replace separate light guides or the like which are used in communication devices of prior art, for example for illuminating the keys or producing illuminated figures in the communication device 1. The functional cover 5 b is primarily designed to correspond to the shape of the second part 5 a in such a way that the functional cover 5 b can be placed against the inner surface of the second part 5 a. Thus, when assembled, this second part 5 a, the keypad 3, the key elements 16, the functional cover 5 b, and the display 4 constitute an integrated functional unit which can be attached to the housing 2 of the communication device by applying mechanisms known as such. It is thus possible to manufacture a variety of replacement covers 5, from which the user can select an alternative suitable for each use and/or according to his/her preference. FIGS. 6b-6 e show some advantageous designs for the replacement cover 5. Different designs may be equipped with different key functions. Furthermore, in different designs, the same key functions can be placed in different ways, wherein the present invention can also be applied in the same functions to consider different use preferences. [0035] This layout for the user interface of the replacement cover 5 b according to the fourth advantageous embodiment of the invention is not dependent on the layout of the other electronics part 21 of the communication device, wherein the properties and location of the display 4 of the communication device 1 can be changed by changing the replacement cover 5. The different replacement covers 5 can be provided with different displays 4, for example a monochrome or colour display. Furthermore, the resolution of the display can vary in the displays 4 of the different replacement covers 5. Thus, for example for playing games and/or browsing in the Internet, the user can change a replacement cover 5 equipped with a display 4 with a higher resolution than the display to be normally used for telephone functions. In this embodiment, no circuit board is needed underneath the keypad 3, wherein the keypad 3 can be made simpler than keypads of prior art. This will also reduce the need for space of the user interface Ul1 of the replacement cover. [0036] Using the above-presented replacement cover 5, the dimensions of the other electronics part 21 of the communication device 1 can be standardized, if necessary, which facilitates the design of new device versions and accelerates product development. Thus, for producing new device versions, it is sufficient that the replacement cover 5 is changed. As already presented above, these replacement covers 5 can be very different from each other, although the first part 2 b of the housing and the other electronics part would remain unchanged. FIG. 7 shows, in a reduced cross-section, a communication device 1 complying with the fourth advantageous embodiment of the invention. The first part 2 b of the housing is equipped with a battery housing for a battery 19, and a cover 20 for protecting the battery 19. The electronics part 21 can be preferably placed in connection with the first part 2 b. [0037] The above-described solution according to the fourth advantageous embodiment of the invention can also be applied in connection with the touch panel mentioned earlier in this description. Thus, the touch-sensitive means 13 is preferably placed in connection with the housing 2. In this case, the replacement cover 5 does not necessarily require a display nor key elements 16. The keystrokes from the keypad 3 are transferred by means of the functional cover 5 b to the surface of the touch-sensitive means 13, wherein the keystroke is detected and the coordinates of the contact point are determined. The second part 5 a of the replacement cover is equipped with an opening or a transparent part in that part of the touch panel which is reserved for displaying visual information in the communication device, that is, substantially at the display area 14 (FIGS. 4a and 4 b). In different replacement covers, the display area 14 and the keypad can have varying layouts and sizes, wherein information is transmitted to the processor 11 of the communication device about the layout of the display area and the keys of the keypad 3 in the different replacement covers. [0038] A communication device 1 according to a fifth advantageous embodiment of the invention comprises a replacement cover which has larger keys or touchable areas than the keys or touchable areas of keypads of prior art mobile communication devices. The larger keys or touchable areas are intended to be better seen and operated by people with reduced eyesight. Also disabled people may have difficulties with using the prior art keypad having small keys. The keys of the replacement cover according to the fifth advantageous embodiment of the present invention are preferably designed so that when a key of the replacement cover is pressed, it presses one key of the actual keypad of the communication device. However, this means that all the keys of the actual keypad can't be implemented in the replacement cover. Therefore, if all the numeric keys are needed, the replacement cover according to the fifth advantageous embodiment of the present invention is suitable for mobile communication devices comprising a keyboard which also has other keys than numeric keys, e.g. alphabetical keys. Then it is possible to arrange all numeric keys which are big enough for people with reduced eyesight and for disabled people. It is also possible that the replacement cover according to the fifth embodiment of the present invention is used with a numeric keypad. In that case only some of the keys of the numeric keypad can be implemented in the replacement cover. This can, however, be enough because many prior art mobile communication devices have a property in which a telephone number can be programmed to one key. Then that number can be selected only by pressing that key, ie. onetouch speed dialing. Therefore it is possible to program the most important telephone numbers to those keys which can be pressed by the keys of the replacement cover. [0039] The above-described solution according to the fifth advantageous embodiment of the invention can also be applied in connection with the touch panel if the size of the touch panel is big enough for implementing larger touchable areas for providing key functions. [0040] The communication device 1 is preferably equipped with detecting means for transferring information, preferably to the processor 11, on whether the replacement cover 5 is attached to the housing 2 of the communication device. Furthermore, if the replacement cover 5 is attached, information is preferably also transmitted on the type of the replacement cover 5, wherein the communication device 1 is capable of reacting correctly to the keystrokes and displaying information in the correct area of the display 4. Moreover, if the touch screen is used, information is transmitted to the processor 11 also on the location of the display area and/or the key layout of the keypad 3. These detecting means may comprise e.g. a switch (not shown) which is in different positions depending on whether the replacement cover 5 is attached to the housing 2 or not. The detecting means can also be arranged in connection with the connector 18, or the keypad 3 and/or the keypad 6 can be used as the detecting means, wherein the user can define the settings. [0041] It is obvious that the replacement cover 5 according to the invention can also be equipped with e.g. a joystick, a control ball, a speaker/earpiece, a microphone, etc. [0042] It is obvious that the present invention is not limited solely to the above-presented embodiments, but it can be modified within the scope of the appended claims. For example, also the housing 2 can be equipped with keys, such as a current switch.
