The selection keys 18 may activate a predetermined function of the multimedia system 10. In one system, the CD function may be activated by selection key 18a, the radio function may be activated by selection key 18b, and the navigation function may be activated by selection key 18c. A single function selection key may function as a “hard key”.
In addition to hard keys, the front panel 12 may also have soft keys 20. The soft keys 20 may select variable functions. The functions may depend on the mode in which the car multimedia system is operated. If the multimedia system 10 is in a CD mode, then the soft keys 20 may correspond to functions associated with the playing of a CD. As shown, ten soft keys may be positioned in the lower margin area of the front panel 12. The hard keys may be assigned a static function regardless of the mode. The soft keys may be assigned variable functions that depends on the mode of operation.
The display 22 may be positioned in the center of the front panel 12. In one system, the display 22 may comprise a dot matrix display that may display of several lines of information. The information may comprise characters, words or pictures, icons or pictograms. Menu information may include menu items belonging to a hierarchically structured menu system for the multimedia system for operating its several functions. The displayed information may comprise status information or menu information. In some systems, status information refers to information indicating a setting and/or condition of the multimedia system. A menu item may not give the user information about a setting or condition of the system. The menu item may allow selection and/or activation of a predetermined function, such as to change a setting. Status information may comprise information informing the user about a setting or condition of the car multimedia system 10. Status information may be the volume, selected waveband (Ultrakurzwelle (UKW), Mittelwelle (MW), Langwelle (LW), amplitude modulation (AM), frequency modulation (FM)), the mode of traffic announcement (on, off), traffic message channel, the selected program type, map scale, CD number, title number, signal strength, volume level, GSM provider, cellular provider, wireless provider, a mail icon informing about a received message, etc.
The status information shown on the display 22 may be used to perform an assigned function. The status information may be selectable and may be activated like menu items. The user may change a setting or condition of the multimedia system 10 by operating a control element to select and/or activate the setting or condition associated with particular status information. In response to an activation, an assigned function may be performed such as a “display received message” function, enabling the user to read the message on the display. The use of selectable status information simplifies the operation of a multimedia system by minimizing the need to call a menu and navigate through the respective menu and sub-menu levels to reach a desired menu item. The status information may provide a shortcut to a desired menu item or function.
In FIG. 2, the display 22 shows status information, menu information, and radio information. The status information may relate to settings of the radio unit 102. A radio status screen may contain three lines of radio station names 24a-c, which may be a part of a longer list containing more radio station names, which may be received by the radio unit 102. The name of the selected radio station 24b may be displayed with a larger font to differentiate it from the other radio station names that were not selected. For the selected radio station name 24b, the respective frequency of radio station 24b may be displayed and indicated with reference numeral 26.
In one system, status information may be shown as icons 30-38 in the lower right margin area of the display 22. The waveband icon 30 may indicate the selected waveband. In one system, the function associated with status information may jump into or view a menu associated with the status information. The function associated with the status information may call a menu that allows the user to select and activate a menu item. This function may be used when a setting change is more complex than a two state switch. The function may display a list of selectable menu items when the status information is selected. If the status information is “waveband” as in the waveband icon 30, a list of different items, such as UKW, MW, LW, AM, FM may be displayed. The user may then select one of these menu items as the waveband setting.
The traffic icon 32 may relate to the traffic announcement mode (TA) and indicates whether the traffic announcement mode is switched on or off. In one system, a textual indicator, such as “TAM” (traffic announcement mode) may be shown in a normal type face, style and/or weight when switched on and shown in a second typeface (e.g. Arial), style (e.g. italics), highlight, and/or weight (e.g. bold) when switched off. In one system, the function associated with status information may turn on or off a particular mode assigned to that status information. In other words a user may toggle a setting on and off in the multimedia system by selecting and activating the associated status information. If the status information is a “traffic announcement” as with traffic icon 32, the user may switch on and off this setting by selecting and/or activating the status information through the traffic icon 32 associated with the “traffic announcement.” The toggling on and off may be a setting that establishes either “traffic announcement on” or “traffic announcement off”.
The traffic channel icon 34 may relate to the traffic message channel mode (TMC) indicating that the multimedia system may receive traffic messages which may be considered or used by the navigation unit for route guidance. The telecom icon 36 may relate to a condition of the telecommunications unit. In one system the telecom icon 36 indicates when a message is received. The received message may be an email, voicemail, SMS message, or another message. The telecom icon 36 may correspond to one or more inboxes and identify a location of a new message (e.g. in one or more of the inboxes). The telecom conditions icon 38 may relates to a condition of the telecommunications unit. In one system the telecom conditions icon 38 may reflect a signal strength such as a GSM signal strength. Alternatively, the telecom conditions icon 38 may reflect a wireless network strength, or another cellular network strength.
The status information icons 30-38 may not only be displayed on the radio status information screen as shown in FIG. 2, but may also be part of other status information screens. The icons 30-38 may be shown on the navigation screen or a telecommunications screen. On the navigation screen, route guidance information or a map, may be displayed instead of the radio information. On the telecommunications screen, any information relating to telecommunications services may be displayed. At least some of the status information icons 30-38 may not relate directly to the main status information. The status information icons 30-38 may indicate settings and modes of different functions or services for the multimedia system 10.
The radio station information screen shown on the front panel 12 in FIG. 2 may contain further status information 42 and options 44. This status information 42 may be the program type selected by the user. In one system, the user may filter the list of receivable radio stations by a program classifier, such as info, classic, pop, etc. As shown in FIG. 2, the selected program type is “info”. The options 44 may be selected to active a menu for changing or adjusting settings or modes of the multimedia system 10.
The change or adjustment of settings or modes of the multimedia system, such as to enable or disable the traffic announcement mode or to display traffic messages, may occur by selecting and activating the respective menu items from the menu system. In some applications, a user may navigate through submenu levels to find the desired menu item; particularly, if the desired setting or mode does not relate to the main status information displayed on the screen. In one system, the status information may be selectable or active. When active, the user may change the mode of the multimedia system 10 through the icons 30-38.
In one system, the selector device 110 enables and disables the highlighting of status information to indicate its selectability. In particular, the status information icons may each be selectable; however, highlighting may be used to indicate which icon may currently be selected. Alternatively, mechanisms other than highlighting may be used to indicate the selectability of status information. A change in color or font may also indicate that status information is currently selected or selectable. The selector device 110 may remove highlights after a predetermined time period expiring without operating a control element. Although status information may not be highlighted, the selectability of respective status information may be maintained on a display. The user may activate the function assigned to the selected status information by operating the control element without re-selecting additional status information.
A user may select the status information “traffic announcement” by navigating the control element to highlight and select that item. The selection may switch on and off the traffic announcement. In one system, the user may switch on and off the traffic announcement by just one operation of the control element as long as the status information remains highlighted after a period of time. Alternatively, the highlighting of a status information icon may be cleared after a predetermined period of time, and a default status information icon may be highlighted. The user may have to reselect particular status information after a time period lapses.
FIG. 3 is a flow chart of a method of using a multimedia system. In block 302, the status information is displayed through icons 30-38. In block 304, the status information is selectable. In block 306, the respective status information is associated with a particular function. In some processes, the waveband icon 30 may enable a waveband, the traffic icon 32 may enable the traffic announcement mode (TA), the traffic channel icon 34 may enable the traffic message channel mode (TMC), the telecom icon 36 may enable a telecom condition detection mode, and the signal strength icon 38 may enable the telecom or meter mode. Each of the status information icons 30-38 may be associated with one function. In block 308, the function associated with the status information icon may be activated by the selection of that status information icon. The telecom mode may be activated by the selection of the telecom icon 36.
FIGS. 4-10 show alternate views of the display 22. The display 22 may have similar status information and similar menu items as shown in FIG. 2. In FIG. 4, arrows 51 are positioned between various status information or menus. In one system, one arrow 51 may link the menu item 44 with the frequency information 26, which in turn may be linked with the status information program type 42. This status information 42 may be linked through arrow 51 with the radio station name 24b which, in turn, may be linked with the waveband icon 30. This waveband icon 30 may be linked with the traffic icon 32 which may be connected with the traffic channel icon 34, that is linked to the telecom icon 36 that is linked to the signal strength icon 38. An arrow 51 may be linked with the menu item 44. The chain of arrows 51 between status information and menu items may illustrate the order in which the status information and menu items are selectable. In some systems the items linked with arrows 51 are each selectable and are selectable in a sequential order of the arrows 51. The multimedia system 10 may allow a user to move a selection mark (or cursor) from one status information to the next. The sequence may occur according to the order indicated by the arrows 51 and in response to an operation of the rotary push-button switch 16 or other control element.
In FIG. 4, a selection mark 60 may identify the selected item and may be displayed as a highlighting of the menu item “options” 44. The selection mark 60 may be moved in a sequence between icons. In FIG. 4, the selection mark may move from menu item 44, to status information 26, to program type information 42, to radio station name 24b, to waveband icon 30, to traffic announcement icon 32, to traffic message channel 34, to menu icon 36, to signal strength icon 38 and then back to the menu item “options” 44 in the sequence shown by the arrows 51. The movement of the selection mark 60 may occur by rotating the rotary push-button switch 16 in a counterclockwise direction. A rotation of the rotary push-button switch 16 in the clockwise direction may reverse the order of selection. Each selectable status information or menu item on the display 22 may be assigned a function, which may be performed (activated) by pushing the rotary push-button switch 16. One function may switch on and off a setting or mode or to display a menu.
FIGS. 5 and 6 illustrate one function associated with status information on display 22. In FIG. 5, the mail icon 36 may be highlighted by advancing the selection mark 60 on to the mail icon 36. The selection mark 60 may be moved by advancing the rotary push-button switch 16 in a clockwise or a counterclockwise direction. The selection mark 60 may be a highlight that indicates the highlighted icon may be activated or selected to perform a function assigned to the icon. To perform the function assigned to this mail icon 36, the user pushes (activates) the rotary push-button switch 16 after mail icon 36 has been selected. As a result, display 22 is changed, as shown in FIG. 6 to display a message.
In FIG. 6, an SMS message is displayed. Messages from e-mail, instant messages, voicemail, or SMS messages may also be displayed. The mail icon 36 function may display a received message. The selection and activation of status information such as the mail icon 36 may allow the user to avoid navigating through complex menus to view mail. In FIG. 6, the mail icon 36 disappears after its selection and activation, but may reappear to indicate new or unread messages. When the “read message” function is performed, the message is flagged as a read message and the mail icon 36 disappears. The remaining status information icons 30, 32, 34 and 38 may be displayed and may be selected by the user regardless of the mode of display. A “back” menu icon may be displayed that allows a user to return to a previous screen, as shown in FIG. 5. In one system, the multimedia system 10 may change to a previous screen after a predetermined period of time.
The status information icons 30, 32, 34 and 38 may be highlighted, selected and/or activated to perform the respective assigned function in a similar process. In one system, if the waveband icon 30 is selected and activated, the multimedia system 10 may display a list of different wavebands the user may select. Such a list may comprise (in Germany) UKW, MW or LW (Ultrakurzwelle, Mittelwelle, Langwelle) or AM, FM (in the United States). By operating the rotary push-button switch 16 or other control element, the user may then select the desired waveband.
If the user selects and activates the traffic announcement icon 32. The user may toggle between a traffic announcement on mode and traffic announcement off mode. The traffic announcement on mode may be displayed in bold characters TA, and the traffic announcement off mode may be indicated by Italic characters TA. If the user selects and activates the TMC icon 34, the received and stored traffic messages may be displayed on the display 22 like the SMS message as shown in FIG. 6. In one system, if the user selects and activates the signal strength icon 38, a screen that can receive a telephone number may be generated and displayed. The functions assigned to the status information icons may vary. In some systems, the status information may comprise additional icons and functions.
The function associated with status information may differ based on the method in which the status information is selected or activated. The selection may be through a control element, such as the rotary buttons 14, 16, or another multi-function control element or device. Different functions may be performed in response to the activation of a particular control element. In some systems, the control element may facilitate a long activation or a short activation depending on the length of activation of the control (e.g., how long a button is activated). For particular status information, a short activation may trigger the on/off toggle function, while a long activation may trigger a menu display. Two unique functions may be assigned to one status information, which may be activated by a short or long activation engagement of the control element. In one system, with the traffic icon 32, selecting a first or short function may turn on or off the function. A second or long function may call a respective menu that allows the changing of other settings related to the traffic announcement mode, such as the volume of the traffic announcement, radio station, etc.
FIGS. 7-10 are alternate diagrams of a status information screen with alternate selections of a status information icon. In FIG. 7, the selector mark 60 is positioned to select the frequency information 26. If a user activates frequency information 26 by pushing the rotary push-button device, the function assigned to the frequency information 26 may be activated. The user may be allowed to change the frequency of the radio by turning the rotary push-button device 16. In FIG. 8, the frequency is changed from 92.2 MHz to 102.2 MHz. A first function assigned to the frequency status information 26 may call an editing mode. A second function assigned to the frequency status information 26 and activatable by different operation of the rotary push button device may initiate a frequency scan. Alternatively, other functions are also possible, such as a first function that may call a menu, which allows for the adjustment of the pitch or the manual adjustment of the frequency.
After a selection and activation performs a desired function, there may be alternatives how the multimedia system proceeds further. The selection mark 16 may disappear as shown in FIG. 9. Although the selection mark 16 is not seen, the frequency status information 26 may be selected and may be activated. This allows the user to change the frequency even at a later time by activating the rotary pushbutton switch 16. Alternatively, shown in FIG. 10, the selection mark 60 may return to a default menu automatically without user interaction. The selection mark 60 may automatically return to the menu item “options” 44 after a period of time. The multimedia system 10 allows for the selection of status information. A selection may activate a function assigned to the respective status information. This function may enable or disable a respective mode or allow more complex settings or options.
In other multimedia systems, status information may serve as an identification to a user. A mail icon may indicate that new mail has been received. New mail viewing may require navigating through a hierarchical menu. Alternatively, status information that is selectable and associated with a function may improve ease of use. The user may scroll through all of the status information and may be able to activate the status information to perform the associated function as in FIG. 11.
FIG. 11 is a flow chart illustrating the use of a multimedia system. In block 1102, the system displays various status information icons. Each of the status information icons may be associated with one function or more. In alternate systems, status information may not be represented by icons, but by text or other symbols. In block 1104, a status information icon is highlighted. The highlighted icon may be a default icon or may be a previously user-selected icon. In block 1106, the user may use a control element to change the highlighted icon. In one system, a control element may be a rotary dial that navigates through the status information icons and may activate the function of a highlighted icon by depressing the dial. One of the status information icons may be highlighted at a time. The control element may change the icon that is highlighted to highlight the next icon as in block 1108. In alternate systems, highlighting may be replaced with color changes, formatting changes, or font changes to indicate which icon is highlighted. The highlighted icon may be selected with a selection mark 60 as in FIG. 10. The highlighted icon in block 1104 may be activated in block 1110. When a status information icon is activated, a function associated with that status information may be performed as in block 1112. As a function is performed or after it is performed, the same icon may be highlighted, or a default icon may be highlighted as in block 1114. The system may return to a mode where one of the status information icons is highlighted as in block 1104 after performing a function.
