TECHNICAL FIELD
The present invention deals generally with user operation of portable electronic devices and deals more particularly a mobile telephones such as a cellular telephone having hinting capabilities for making a user aware of possible next functions available for selection.
BACKGROUND OF THE INVENTION
There has been an increasing demand for more and more features in portable electronic devices, particularly mobile telephones such as for example, cellular telephones. Generally, the operation of the features are carried out by operating a combination of one or more keys which may be selection keys or alphanumeric keys such as typically found on and used with cellular telephones. One such prior art cellular telephone is shown in FIG. 1 and generally designated 10. The cellular telephone includes a display 12 for displaying text and/or graphics, selection keys 14, 16 for selecting desired operational functionalities of the cellular phone, keypad means generally designated 18 for inputting alphanumeric characters to the phone, a scrolling means generally designated 20 which may be part of the keypad 18 for navigating sub-operational functionalities within a selected operational functionality, and various control keys 22 and 24, for example, to send a call or end a call. The alphanumeric keys 26, 26 may be part of a physical keypad 18 as illustrated or may be part of a virtual keypad, for example a keypad representation on the display screen of the device (not shown) and operated in a well known manner including pen and touch screen operation.
Many of the features included with the portable electronic device such as the cellular telephone are complex and their operation may be menu driven with multiple selection options available through nested sub-menus as illustrated in cascading menu form in FIG. 2 for example. Often, the menu sub-operation selections are not intuitive and cause the user to guess at which operations or key selections should be made to perform the desired operation selection for a given selected desired function.
Further, other features and functions may not be frequently used to enable the user to memorize the necessary sequence of operation steps to carry out the desired selected function much less to become proficient with the operation of the desired feature. Generally, user manuals accompany the portable electronic device to explain the step-by-step operations necessary to carry out the desired function. Obviously, it is inconvenient to carry and time consuming to refer to the user manual each time the user wants to select and operate a feature, particularly an unfamiliar feature or function. It is difficult, even with the user's manual to know with certainty which menu selection step to take in the sequence of steps to carry out or progress in the desired feature or function. Even with practice it takes some time to learn with confidence the steps and possible operational functions available for selection to carry out the desired feature or function.
It would be desirable to provide portable electronic devices such as mobile telephones and particularly cellular telephones that overcome the limitations and deficiencies of the prior art in learning, selecting, and operating desired features and functions of the device.

The functionalities are typical of that available with cellular telephones and may include, for example, short text messaging, connection to the computer global network, selections of prior pre-programmed messages, list of addresses, names, or other typical addresses and information and data associated with conventional cellular telecommunication devices. The scroll key 112 is shown as having directional capabilities which are activated by pressing on the marginal areas 114, 116, 118, 120 to navigate or move about through the particular display graphic, pictorial or text shown on the display 102 in an upward and a downward vertical direction or a sideward left and right horizontal direction. The scroll key 112 also includes a central portion 122 which functions as an entry or selection contact switch typically by pushing on the center of the scroll key to effectuate operation. The cellular telephone 100 additionally includes other control keys, for example, a talk key 124 which is typically used to send a message or to initiate a dialing sequence to complete the call, and a control key 126, for example, which is used to end or terminate a call. The cellular telephone 100 also includes additional control keys 128, 130, 132 which are typically used to access various functions and features of the cellular telephone and as explained in further detail herein below are utilized with other keys to make a user aware of one or more next possible sub-operational functionalities available for user selection in the selected operational functionality, in other words, providing a hinting capability for operation of a next function selection from the current step in the call progression or function access sequence. Although the cellular telephone 100 is disclosed herein in numerous illustrative embodiments of the present invention, it will be recognized that the cellular telephone 100 may also operate in a conventional menu driven mode such as shown, for example, by the menu sequence illustrated in FIG. 2.
Turning now to FIG. 4, one embodiment of the mobile phone of the present invention has various illuminated keys to hint at or make the user aware of next possible sub-functionality options available for selection and is illustrated schematically therein and generally designated 100. For purposes of explanation and illustration of the invention, the specific desired function selected deals with accessing the global computer network wherein the user has operated one of the selection keys, for example, 108, 110 to initiate the desired operational functionality. As illustrated in FIG. 4, the user is made aware that function to access the global computer network requires an additional action as indicated by the instruction text message “Enter URL” designated 134 and shown on the display 102 and the appearance of a window 140 on the display 102. The user at this stage of the sequence to access the global computer network can either guess at what the next possible step or action should be or in accordance with the present invention, observe that the control key 128 is illuminated and that the scroll key 112 is illuminated. The illuminated keys 128 and 112 hint or suggest to the user that operating one of these keys might somehow be related to the function of entering the URL to gain access to the global computer network. Thus, it is suggested to the user by the cellular telephone 100 by way of the illuminated keys 112, 128 that the user could possibly operate one or the other of these keys to achieve the intended function to access the global computer network. For purposes of example and explanation of the present invention, the user may decide to operate the control key 128 and which operation causes the beginning character string “www.” of a URL address to be shown in the text window 140 on the display 102 of the cellular telephone 100 as illustrated in FIG. 5. The appearance of the initial character string “www.” of the URL address as illustrated in FIG. 5, suggests to the user and hints that a further entry is required. In this context, the user is aware that the scroll key 112 is illuminated to suggest that this key has a possible operational relationship to the function that is being attempted, and in this example, accessing the computer global network. The user may then operate the scroll key 112 by pushing on the center region 122 which causes a history list of URL's 150 to be shown on the display 102 as illustrated in FIG. 7. The scroll key 112 continues to be illuminated as illustrated in FIG. 7 suggesting to the user that further possible functionality is available through operation of the scroll key 112 such as, for example, the ability to navigate or move through the list of URL addresses shown on the display 102. As illustrated in FIG. 8, the user may navigate through the list of URL addresses using the scroll key 112 to highlight each address to identify to the user the location of the scrolling cursor in a well known manner to select for example a desired address as highlighted and generally indicated 152. If the URL address 152 is the address that the user desires, operating the scroll key 112 by pushing on the center region 122 causes the URL address to appear in the window 140 as illustrated in FIG. 9. Still referring to FIG. 9, the scroll key 112 and the talk key 124 are illuminated suggesting to the user that either one or both of these keys may be available for possible further functionality selection. In this context, the scroll key 112 may be operated to cause the URL address history list 150 to reappear on the display 102 and to make a different URL address available for selection. Alternately, in this context, the user may determine that the selected URL address shown in the window 140 is the desired and correct URL address and then operate the talk button 124 to send the URL address from the cellular phone 100 in a well known manner to access the global computer network.
Referring again to FIG. 4 and considering an alternate user operating sequence, the cellular telephone 100 is illustrated with an illuminated scroll key 112 and illuminated control key 128 to make the user aware of and hint at possible operations for entering the URL address in accordance with the text instruction message “Enter URL” 134 shown on the display 102. In this example, the user operates the illuminated control key 128 with the resulting URL address leading character string “www.” being shown in the window 140 of the display 102 as illustrated in FIG. 6. In this context operation of the control key 128 causes the alphanumeric keys 106, 106 of the keypad 104 to illuminate suggesting to the user that the alphanumeric keys 106, 106 are somehow related to the next possible user operation to access or complete the selected desired functionality. In the context presented in FIG. 6, the cellular telephone 100 hints that operation of the alphanumeric keys 106, 106 may be used to enter the remaining characters of the character string for the desired URL address.
Turning now to FIG. 10, the cellular telephone 100 is illustrated therein with the alphanumeric keys 106, 106 of the keypad 104 illuminated to suggest or hint to the user that the keys 106, 106 are somehow related to the context and sequence of entering the URL address in the window 140. The user then selects the appropriate illuminated alphanumeric keys 106, 106 of the keypad 104 to enter the desired URL address in the window 140 shown on the display 102 as illustrated in FIG. 11. As shown in FIG. 11, the alphanumeric keys 106, 106 are extinguished after the URL address is entered and the talk key 124 is now illuminated suggesting to the user that operation of this key is a next possible function available for access to send the URL address from cellular telephone 100 to access the global computer network.
In a further alternate embodiment of the present invention as illustrated in FIG. 12, the cellular telephone 100 shows on the display 102 a history list of URL's 150 as a consequence of operating the scroll button 122, during the sequence progression steps in the desired operational functionality for example, in the context shown in FIG. 6 to bring up and show the history list as illustrated in FIG. 7 and also cause the appearance of the leading character string “www.” of a URL address in the window 140. In FIG. 12, the alphanumeric keys 106, 106 are illuminated suggesting to the user that these alphanumeric keys 106, 106 are somehow related to the next possible sub-functionality operation available for selection for accessing the global computer network. In the example shown in FIG. 12, the user may key in the URL address using the alphanumeric keys 106, 106 in accordance with the desired URL address 154 illustrated or shown in the URL history list 150. Upon entry of the appropriate URL address, the talk key 124 will illuminate suggesting to the user that this key is a next possible sub-functionality operation available for selection to complete the access to the global computer network. The alphanumeric keys 106, 106 may continue to be illuminated or may be extinguished in accordance with the desired cellular telephone operation.

The user then operates in step 464 one of the keys identified in step 460 and illuminated or displayed in step 462. Upon operation of the given key the sub-functionality corresponding to the associated key is displayed in step 466. The method may return to step 464 to operate additional keys and display the sub-functionality corresponding to the associated operated key in step 466. If no additional keys are operated in the method step 464 then the desired functionality is selected in step 468 and the desired function is completed in step 470 with the method ending with step 472. If it is determined in step 458 that no additional functionalities are available for the function selected in step 454 the system moves to the step 470 to complete the desired function and the method ends with the end step 472.
FIG. 23 illustrates a flow chart generally designated 500 showing an alternate embodiment of the method of the present invention for hinting at next possible sub-operational functionalities available for selection corresponding to the given operational context and sequence progression step in the selected desired operational functionality in the mobile telephone, particularly a cellular telephone. The method begins with the start step 502 wherein the user identifies a particular or specific feature or function is identified. The desired feature or function is selected in 504 and the operation of the key or other action is detected in step 506. It is next detected in step 508 if additional sub-functionalities are available for selection for the desired function selected in step 504 corresponding to the detected operating sequence in 506. If additional sub-functionalities are available, the associated sub-functionality key is identified in step 510. The method then determines in step 512 whether additional sub-functionality keys are available and if so, the method returns to step 510 to identify the associated sub-functionality key. If it is determined in step 512 that no additional sub-functionality keys are available, a key corresponding to the desired functionality is operated in step 514 to select the functionality. The method then moves to step 516 to display the functionality corresponding to the key operated in step 514. The displayed functionality is selected in step 518 and its operating sequence is detected in step 506. The method will then determine in step 508 if additional sub-functionalities are available based on the selected functionality in step 518 and on the operating sequence detected in step 506. If additional sub-functionalities are available as determined in step 508 the method then moves to step 510 to identify the associated sub-functionality key and proceeds as described above. If it is determined in step 508 that no additional sub-functionalities are available for the desired function selected in step 504 as detected through the operating sequence of step 506 the method moves to step 520 to complete the desired function. Likewise, the system moves to complete the functionality selected in step 518 and terminates with the end step 522. It will be recognized and appreciated that multiple iterations may occur depending upon the specific sub-functionality selected in the method causing different associated sub-functionality keys to be identified to hint at next possible user operation according to the given operational context and sequence progression step in the selected desired operational functionality.
Turning now to FIG. 24, a flowchart generally designated 550 illustrates a further alternate embodiment of the method of the present invention for hinting at next possible sub-operational functionality available for selection corresponding to the given operational context and sequence progression step in the selected desired operational functionality during operation of the mobile telephone. The method that begins with the start step 552 wherein the function or feature desired for selection is selected in step 554. The method determines in step 556 additional sub-functionalities available corresponding to the desired function selected in step 554. The system then identifies in step 558 corresponding available functionalities for the selected function. The method then displays all the key symbols or icons associated with the identified available sub-functionalities in step 560. The method then operates a key corresponding to the key symbol or icon displayed in step 562 which causes the functionality associated with the operated key to be displayed in step 564. It is next determined in step 566 if the desired functionality is displayed. If the desired functionality is displayed then the method moves to step 568 wherein the functionality is selected and the desired function is completed in step 570 and terminates with the end step 572. If it is determined in step 556 that no additional sub-functionalities are available, the system moves to step 570 to complete the desired function and terminates with the end step 572. If it is determined in step 566 that the desired functionality is not displayed then the system moves to step 574 to determine if additional keys are available. If additional keys are available then the system moves to step 562 and the key corresponding to the additional available functionality key is operated and the functionality associated with the operated key is displayed in step 564. If the desired functionality is displayed in step 566 then the method moves to step 568 to select the displayed functionality and the method continues as described above. If in step 574 it is determined that no additional keys are available then the method moves to step 568 to select the displayed functionality or terminates with the end step 572.
A mobile telephone such as a cellular telephone having hinting capabilities for making a user aware of possible next functions available for selection corresponding to the given operational context and sequence progression step in the selected desired operational functionality has been described above in several preferred embodiments along with a related method for carrying out the hinting capability in the mobile telephone. Numerous changes and modifications may be made by those skilled in the cellular telephone art, for example, the sequence of presenting a history list of URL addresses may appear at different progression steps other than that described above. In addition, other control keys and selection keys may be available and other activation means such as voice activation and audio response may be employed to carry out the function and intent of the present invention. Therefore, the present invention has been described by way of example rather than limitation.
