- no such memory is necessary for other functions, however, such as the Del key.
- Activation of a key by the key selection and activation means may be accomplished by further actuation of the key selection and activation means. This requires the operator to act actively to activate a selected key, be it a character key or a function key.
- the communication device may be configured to include a control device configured to display the alphanumeric character associated with the currently selected active character key in the display device upon expiration of a predetermined period of time without changing the active key, and / or activates the control function assigned to the currently selected active function key.
- a control device configured to display the alphanumeric character associated with the currently selected active character key in the display device upon expiration of a predetermined period of time without changing the active key, and / or activates the control function assigned to the currently selected active function key.
- This is also a possible way to activate a key through the key selection and activation means. In this case, the operator only needs to select the active key which he wishes to display on the display device and, after having selected the desired key as the active key, only has to wait until the predetermined time has elapsed.
- the key selection and activating means may comprise a selector switch which is displaceable in a first direction and in a second direction different from the first direction, preferably orthogonal to the first direction to issue a second actuation signal.
- the selector switch may be constructed as a "joystick" already present on numerous cell phones to navigate through user menus, contact lists, received messages, and so on.
- Relocatable in this context includes both a translational movement and a rotational movement.
- the same selection switch can be used not only to select an active key but also to activate it. This can be realized in such a way that the selector switch can be displaced in a third direction different from the first and the second direction, preferably orthogonal thereto, in order to output a third actuation signal. For example, the selection switch can be pressed to activate the previously selected active key.
- the selection switch can be made larger than the character and function keys of the keypad, so that it is easier to operate such a selection switch than to operate character or function keys.
- the key selection and activation means may comprise a plurality of selection switches, eg in the form of a known navigation key arrangement.
- a switch can be provided for each direction of navigation, for example up, down, left and right.
- a currently active key may be activated by simultaneously actuating at least two of the directional switches of the selector switch assembly.
- a further switch for activating the currently active key can be provided.
- the directional switches may be formed and arranged in the shape of arrows pointing in the direction associated with the respective switch.
- the additional activation switch may be located in the middle of the directional switches.
- the key selection and activating means comprises at least one sensor for detecting a change in a spatial orientation of the communication device with respect to a stationary coordinate system, wherein an actuation of the Tastenaus Hor Horzing- and Activation agent is carried out by changing the spatial orientation of the communication device.

- the key selection and activating means may additionally or alternatively comprise at least one acceleration sensor, so that the key selection and activating means are triggered by shaking the apparatus along predetermined Spaces can be actuated.
- an acceleration sensor is provided for each actuation direction.
- shaking the communication device along two mutually orthogonal directions may serve to select the active key among the plurality of keys of the keypad while shaking the communication device along a third direction, which is preferably orthogonal to both the first and second directions. can be used to activate the currently selected active key.
- the display means is any means which is adapted to display the active key of an operator.
- This indication may be visual and / or mechanical and / or auditory and / or tactile.
- each selectable and activatable button of the keypad may be associated with a section of electrochromic material to which an electrical voltage is applied when the respective button is currently active. The electrochromic material then changes color.
- the key may be at least partially made of such an electrochromic material.
- the keys may be configured to have a variable shape, particularly with regard to the dimension with which they protrude from the housing. Consequently, the currently active key may protrude more or less out of the housing than the remaining non-active keys. Such a function can be realized as described in document WO 2005 062323 A.
- the speaker of the communication device may be used to acoustically output the character and / or the function associated with the currently active key.
- the communication device may be provided with a memory in which is stored data needed to output the character or the function by an artificial voice.
- the display means comprises illumination means, so that the respective selected active key one Illuminated state, which is different from that of the non-active buttons.
- "Different illumination state" in the context of the present application includes both situations in which only the currently selected active button is illuminated, and situations in which the currently selected active button is illuminated brighter or darker than the remaining non-active buttons, as well This latter situation has the advantage that even the non-active keys are readable when the ambient lighting conditions are poor.
- Two lighting conditions may also differ according to this application if the lighting of the currently active key flashes at a frequency different from that of the non-active keys, which includes the case that only the active key is flashing. It is also considered to be a different lighting condition according to the present invention when the currently selected active key is illuminated with a light having a different color compared to the non-active keys. In order to increase the ease of perception of the currently selected active button, combinations of the above ways and ways of establishing different illumination states may be used.
- One way to illuminate the active button (s) and / or the non-active buttons without significantly increasing the number of components of a communication device is to use the backlighting commonly used to illuminate the keys of portable communication devices, particularly mobile phones and cordless phones, is present.
- the illumination means are associated with such a backlight.
- a backlight control device has to be provided, which is designed to control the backlighting of individual keys in such a way that the intensity and / or the color or / and the flashing frequency of individual keys can be set.
- Fig. 1 is a plan view of an embodiment of the present invention.
- Fig. 2 is a plan view of the portable electronic communication device of Fig. 1 after operation of a key selection and activating means provided on the communication device.
- Fig. 1 shows a hand-held mobile telephone 10 as an embodiment of a portable electronic communication device.
- This mobile telephone 10 comprises a housing 12 with a display device 14 and a hardware keypad 16, which is formed separately from the display device 14.
- a joystick 18 is then provided in the housing 12 between the display device 14 and the keypad 16.
- the keypad 16 includes a plurality of character keys, each of which is associated with one or more alphanumeric characters, forming a QWERTY keyboard.
- the space key 22 is also considered a character key. In those cases where one and the same character is associated with a same character key 20 as both a capital letter and a lower case letter, selection between the uppercase and lowercase characters may be made by activating a shift key 24. The lowercase letter is selected as the default. Incorrectly entered characters can be deleted by activating a delete key 26. If different characters are assigned to the same character key 20, these different characters can be selected by activating a Ctrl key or by activating an Alt key 30.
- the Shift key 24, Delete key 26, Ctrl key 28 and the Alt key 30 are examples of function keys. It is also conceivable for one and the same function key to have two or more functions assigned to it, which in turn can be changed by, for example, using the switching function. Button 24 can be selected. Again, a function is selected in the default setting.
- pressing a character key activates the associated alphanumeric character for display in the display device 14. This means that pressing the character key causes the associated alphanumeric character in the display device 14 is displayed at a current cursor position.
- the cellular phone 10 shown in Fig. 1 provides a special mode of simplified input.
- the backlight of the keypad 16 is turned on, illuminating all the keys 20 to 30 of the keypad 16 by emitting light and passing through the interior of the housing 12 through transmissive portions of the keys 20 to 30 of the keypad 16 is transmitted.
- a key which is set in a default setting as an active key at the time of entering this mode is illuminated differently than the other keys.
- a centrally located key eg, the key 20a
- This key 20a is lit brighter than the remaining keys of the keypad 16, which is indicated at 21.
- this currently set active key 20a may have a backlight of different color compared to the remaining keys of the keypad 16 and / or may flash at a particular frequency while the remaining keys of the keypad 16 are illuminated continuously.
- the joystick 18 is part of the key selection and activating means.
- the joystick can be tilted in four directions u, d, 1 and r, as indicated by the respective arrows in FIG. Further, the joystick 18 may be pressed in a direction orthogonal to the drawing plane of FIG.
- FIG. 2 shows a situation after the joystick 18 has been operated once in the direction of the arrow d from the situation of FIG. 1 and has been operated twice in the direction of the arrow 1. Consequently, the character key 20 is now selected as the active key, while the selection of the character key 20a is canceled.
- the joystick 18 is depressed in the situation of FIG. 2, the character associated with the currently selected active key 20b is displayed in the display device 14.
- the joystick 18 is used to navigate through the keys of the keypad 16 to select a key and to activate that key. This operation corresponds to an immediate pressing of the button 20b and leads to the same result.
- the selection of an active key from the plurality of keys 20 to 30 of the keypad 16 may be accomplished by tilting or shaking the cellular phone 10 in a corresponding direction of actuation.
- the mobile phone 10 must be equipped with corresponding sensors that are able to detect the tilting and / or the acceleration of the mobile phone 10 in a particular direction. In this way, for example, by shaking the mobile phone 10 in a direction orthogonal to the drawing plane of Figures 1 and 2, not only the selection of an active key but also their activation can be controlled.
- the keys denoted by 32 in Fig. 2 are so-called “softkeys” having varying functions
- the momentary function associated with the keys 32 is indicated in the display device 14 above the respective key 32.
- the keys 34 are left and right of the joystick 18
- the keys 34 may also be used as "softkeys" in the manner described above and well known.
