     FIELD OF PRESENT INVENTION 
     The present invention relates to the field of wireless mobile telephony. More specifically, the present invention relates to visualization of various non-visual aspects of wireless mobile telephony to further improve the usability of wireless mobile phones. 
     BACKGROUND OF THE PRESENT INVENTION 
     Advances in integrated circuit and telecommunication technology have led to wide spread adoption of wireless mobile client devices, in particular, wireless mobile phones. Wireless mobile phones are popular, partly because they offer the advantage of enabling their users to be communicatively reachable by their business associates, friends and family members, wherever the users may be, as long as they are within the reach of the service networks. 
     Ever since their initial introductions, the cost for owning and using a wireless mobile phone has steadily declined. Today, the cost for owning and using a wireless mobile phone is well within the ability of many non-professionals. In fact, as the cost for air time continues to decline, wireless mobile phones have become the first medium of communication for non-professionals as well as professionals. When the need to make a call arises, a wireless mobile phone user will reach for their wireless mobile phone first, even if a traditional wired line telephone is readily available. 
     At the same time, successive generations of wireless mobile phones have also packed more functions and performance while reducing in size. Today, virtually all wireless mobile phones offer core functions such as dial list, call log, and so forth, while many high end models offer advanced functions such as emails and Internet access. 
     However, there remains a number of situations where the current generation of wireless mobile phones do not adequately address the users&#39; needs and further improvements are needed. One of these situations is where audible operation of a wireless mobile phone is prohibited or inappropriate. In addition to theaters, many restaurants have joined the rank of commercial establishments requesting their patrons to turn off their wireless mobile phones to enhance the enjoyment of other patrons. In circumstances like these, under the prior art, a user would have to either turn off the wireless mobile phone, or go into a “silent” mode to be notified of an incoming call. For the former option, the user will no longer be able to receive an incoming call, and is communicatively disconnected from the user&#39;s colleagues and friends. As to the latter option, generally, it means placing the wireless mobile phone in a vibrational mode of operation. Under this mode, a wireless mobile phone appropriately equipped with the proper vibrational features would notify a user of an incoming call through activation of a vibration unit included with the wireless mobile phone. However, once notified, generally there is no convenient way for the user to take and engage in the call. If the user desires to take the call, generally the user has to leave the environment that “imposed” the requirement. 
     Another situation is in the area of content presentation. While as alluded to earlier, many high end models provide for Internet access, generally, for bandwidth and other reasons, the world wide web (WWW) contents are edited, with substantial amount of the multi-media contents removed. As a result, user experiences are generally less satisfying when compared to e.g. accessing the WWW using a personal computer. 
     As those skilled in the art of wireless mobile telephony would appreciate, these are but a couple of examples of the limitations of the current generation of wireless mobile phones. One of the primary sensory abilities of a human being is the sensory of vision. Thus, as wireless mobile phones are increasingly becoming a personal accessory, it is desirable in general for wireless mobile phones to have greater abilities to visually present information or visually complement other conventional non-visual features.

     DETAILED DESCRIPTION OF EMBODIMENTS OF THE PRESENT INVENTION 
     Embodiments of the present invention provides for visualization of various non-visual aspects of wireless mobile telephony to further enhance the usability of wireless mobile phones. Among the various visualizations contemplated are visualization of telephony events, alphanumeric contents of messages and web pages, and sound. Visualization of telephony events includes visualization of incoming call notifications and key stroking patterns (e.g. for menu selection). However, from the description to follow, it will be apparent that the visualization teachings of the present invention may also be applied and practiced with other non-visual aspects of wireless mobile telephony. 
     Further, in the description to follow, for purposes of explanation, various details are set forth in order to facilitate a thorough understanding of the present invention. However, the present invention may be practiced without some or many of the specific details. In other instances, in order not to obscure the illustrated embodiments of the present invention, well-known features are omitted, simplified or merely briefly described. 
     The description will be presented using terms that are commonly employed by those skilled in the art of wireless mobile telephony to convey the substance of their work to others skilled in the same art. Examples of these terms include but are not limited to incoming calls, detecting, determining, requesting, and so forth. As those skilled in the art of wireless mobile telephony would appreciate, these quantities may take the form of electrical, magnetic, or optical signals, and the operations involve corresponding processing of these signals by electrical, magnetic, or optical components. 
     The term “wireless mobile phone” as used herein (in the specification and in the claims) refers to the class of telephone devices equipped to enable a user to make and receive calls wirelessly, notwithstanding the user&#39;s movement, as long as the user is within the communication reach of a “service or base station” of a wireless network service provider. Unless specifically excluded, the term “wireless mobile phone” is to include the analog subclass as well as the digital subclass (of all signaling protocols). 
     Various operations will be described as multiple discrete steps in turn, in a manner that is most helpful in understanding the present invention. However, the order of description should not be construed as to imply that these operations are necessarily order dependent. In particular, these operations need not be performed in the order of presentation. 
     The phrase “in one embodiment” will be repeatedly employed in the description to follow. In general, the phrase does not refer to the same embodiment, although in some instances it may. 
     Referring now to  FIG. 1 , wherein a block diagram illustrating a functional view of the present invention, in accordance with one embodiment, is shown. As illustrated, in accordance with the present invention, wireless mobile phone  1100  is provided with a number of light emitting diodes (LEDs)  1114  and visualizer  1102 . Further, visualizer  1102  includes in particular visualizer controller  1112 . For the illustrated embodiment, visualizer  1102  also includes a number of visualization agents  1104 – 1108 . More specifically, visualization agents  1104 – 1108  include event visualization agent  1104 , text visualization  1106 , and sound visualization agent  1108 . 
     LEDs  1114  are employed by visualizer  1102  to effectuate visualization of various non-visual aspects of wireless mobile telephony to enhance a user&#39;s experience in using wireless mobile phone  1100 . More specifically, the desired visualizations are effectuated by visualization controller  1112  selectively activating and de-activating selected ones of LEDs  1114  in selected manners, as requested by the requestors it serves. For the illustrated embodiments, these requesters include visualization agents  1104 – 1108 . 
     Beside LEDs  1114  and visualizer  1102 , for the illustrated embodiment, wireless mobile phone  1100  also includes other hardware and software components  1122 – 1124 . Other hardware components  1122  include in particular a microprocessor for processing instructions, an input keypad for entering data and commands, a visual display for displaying information for the user, and a transceiver for sending and receiving signals wirelessly. Other software components  1124  include in particular corresponding device drivers (e.g. for controlling the input keypad and the visual display), system services (e.g. graphics and audio services), a browser (e.g. for accessing the WWW), and various applications (e.g. dial list, call log, and so forth). Typically, at least selected ones of these system services, the browser and/or the applications include menus of commands for user selection. 
     For the illustrated embodiment, other hardware and software components  1122 – 1124  of wireless mobile phone  1100  include in particular the facilities necessary to practice the conduct of a non-audible call, using Morse codes. Conducting non-audible calls, in particular, through employment of Morse code, is the subject of incorporated by reference application &#39;587. The required facilities are described in detail therein. Readers are directed to application &#39;587 for details. 
     For the illustrated embodiment, these other hardware and software components  1122 – 1124  of wireless mobile phone  1100  also include in particular the facilities necessary to practice the selection of menu items by stroking or gliding over the input keys of the input keypad in various pre-determined stroking or gliding patterns. Data entry and/or menu item selection by way of key stroking or gliding patterns is the subject of incorporated by reference application &#39;197. The required facilities are described in detail therein. Readers are likewise directed to application &#39;197 for details. 
     Continuing to refer to  FIG. 1 , the number of LEDs  1114  to be employed as well as the manner in which they may be arranged are embodiment or configuration dependent. In one embodiment, a single column of LEDs  1114  disposed on a side surface of wireless mobile phone  1100  (as illustrated by  FIG. 3   a ) is employed. In another embodiment, a collection of LEDs  1114  “integrally” arranged around or under the input keys of wireless mobile phone  1100  (as illustrated by  FIG. 4   a ) is employed. In general, more variations, patterns and manners of visualization may be effectuated if more LEDs  1114  are employed. However, for each embodiment or configuration, the number of LEDs  1114  employable is constrained by cost, as well as by the spatial limitations imposed by the physical dimension and the number of other features included with the particular embodiment/configuration of wireless mobile phone  1100 . 
     LEDs  1114  are presently preferred for their relatively low power consumption and compactness in size. Together, these attributes allow a higher number of individually illuminable light sources to be employed. In turn, the higher number of illuminable sources allows more variations in the manner the illuminable light sources may be arranged and disposed. However, in alternate embodiments, other light sourcing elements having attributes consistent with the design objectives and constraints may also be employed for the practice of the present invention. Accordingly, the term “LEDs” as used herein and in the claims are to be broadly construed, and given its conventional meaning as well as an expansive meaning including light sourcing elements with like attributes. 
     As described earlier, visualization controller  1112  is employed to perform the earlier described selective activation and deactivation of selected ones of LEDs  1114  in selected manners. The performances are made responsive to the requests of various visualization agents  1104 – 1108 . For the illustrated embodiment, each of the various visualization agents  1104 – 1108  is responsible for invoking visualization controller  1112  to direct the activations and deactivations of LEDs  1114  to achieve the desired visualization for a corresponding non-visual aspect of wireless mobile telephony. 
     More specifically, event visualization agent  1102  is responsible for invoking visualization controller  1112  to direct LEDs  1114  to effectuate visualization of various telephony events associated with wireless mobile telephony. For the illustrated embodiment, these telephony events include in particular the arrival of an incoming call, as well as the key stroking pattern for selecting a menu item (see  FIG. 8   b , ref.  1804 ). 
     Similarly, text visualization agent  1106  is responsible for invoking visualization controller  1112  to direct LEDs  1114  to effectuate visualization of various textual contents associated with wireless mobile telephony. For the illustrated embodiment, the textual contents include in particular textual contents of messages associated with a non-audible call, conducted using Morse code (see e.g.  FIG. 8   a , ref.  1802 ), as well as textual contents of web pages (see e.g.  FIG. 7   a , ref.  1702 ). In other words, the present invention may be employed to enhance the user experience associated with operating in a “silent” mode, learning to use Morse code to conduct a non-audible call, or viewing multi-media content reduced web pages. Sound visualization agent  1108  is responsible for invoking visualization controller  1112  to direct LEDs  1114  to effectuate visualization of sounds associated with wireless mobile telephony and auxiliary functions (see e.g.  FIG. 7   b , ref.  1704 ). 
     In various embodiments, the various sounds may include audio output of an included radio or an included MPx player or streaming audio (where MPx is one of the Moving Picture Expert Group audio standards, such as MP3, MP4 and so forth). In other words, the present invention may be employed to enhance the user experience associated with enjoying locally rendered or streamed audio. 
     In other embodiments, the various sounds may include audio input picked up from the microphone. The audio may be “meaningful” ambient sounds. Examples of “meaningful” ambient sounds include but are not limited to music picked up from the ambient while the user of the wireless mobile phone is attending a concert with the phone, or crowd noise picked up from the ambient while the user of the wireless mobile phone is present in a sporting event with the phone. 
     Concert may be concert of any music type, country western, rock &#39;n roll, pop, rap, jazz, classical, and so forth. Sporting event may be sporting event of any type, baseball, basketball, football, soccer, volleyball, swim meet, track, and so forth. 
     In various embodiments, the LEDs may be lit deterministically or pseudo randomly with at least one of the number of LEDs employed, the locations of LED employed, the color of the LEDs employed, and the intensity of the LEDs employed having a functional relationship to at least one attribute of the audio. 
     Attributes of the audio include but are not limited to volume, frequency band/spectrum, treble, bass, presence of certain instruments, presence of certain notes, and so forth. 
     In various embodiments, LEDs or groups of LEDs are correspondingly disposed underneath the input keys of the input keypad. Preferably, multiple color LEDs and/or multi-color LEDs are employed. 
     For selected ones of these embodiments, a graphic equalizer is animated using the correspondingly disposed LEDs. In some embodiments, the different spectrums are animated on different columns of the LEDs, with the number of LEDs lit in each column corresponding to the volume of the audio in the corresponding spectrum, while in others, the different spectrums are animated on different rows of the LEDs, with the number of LEDs lit in each row corresponding to the volume of the audio in the corresponding spectrum. 
     Further, in various embodiments, different colors are employed for different volume levels. For example, in a columnar embodiment, the color white is employed for the LEDs disposed with the first two rows of keys, the color yellow is employed for the LEDs disposed with the second two rows of keys, and the color red is employed for the LEDs disposed with the third two rows of keys. Of course, in alternate embodiments, the present invention may be practiced with different colors, and different row grouping of LEDs. 
     In other embodiments, in lieu of a graphic analyzer, a geometric primitive, a pattern, a thing, an object, a person or an animal may be animated instead. For example, a pattern or a geometric primitive, such as a spiral, a helix, or a vortex may be animated in accordance with one or more attributes of the audio. As a further example, an instrument, such as a guitar, a trumpet, a saxophone, a guitar, a drum, a pair of drumstick may be animated based on the presence of the instrument and/or attribute(s) of the audio (associated with the instrument). A ball, such as a baseball, a football, a basketball, a soccer ball, and a volleyball may be animated based on the volume of the ambient audio. Similarly, a mascot, such as a ram, a dolphin, a bronco, a lion, a tiger, a buffalo, a colt, a sea hawk, or a person, such as a pirate, a patriot, may also be animated based on the volume of the ambient noise. In yet other embodiments, the LEDs may be lit to animate “dance steps” based on selected attributes of the audio (music). Resultantly, a user of the wireless mobile phone may finger dance to the music, by tapping on the corresponding keys, following the animation. 
     For the illustrated embodiment, visualizer controller  1112  advantageously offers at least two manners, a visualization agent may request a visualization operation or visualization operations to be performed. These two manners include a first manner where a singular round of activation and deactivation of LEDs  1114  may be requested, and a second manner where a number of rounds of activation and deactivation of LEDs  1114  may be simultaneously requested via a single request. 
     In one embodiment, the first manner is requested via a function call to visualization controller  1112 , providing controller  1112  with the identifiers of LEDs  1114  to be activated, and the corresponding durations of activation. For this embodiment, all other unspecified LEDs  1114  are assumed to remain deactivated. In alternate embodiments, group specifications in particular, an “ALL” LED group may be advantageously supported. Additionally, in various embodiments, the intensity or brightest of each LED may be specified (e.g. by way of an intensity/brightness index in the range of 0 through 16). Further, for multi-colored LEDs, the color may be specified. 
     In one embodiment, the second manner is requested via a function call to visualization controller  1112 , providing controller  1112  with a pointer to a starting location in the included memory of wireless mobile phone  1100 , where a data structure containing a series of rounds or cycles of activation and deactivation specifications is stored. The function call, in addition to the pointer, also includes a size of the data structure. In alternate embodiments, a predetermined end of structure demarcation may be employed, in lieu of a size specification. For each round/cycle of activation and deactivation, the LEDs to be turned on and off are identified. For example, for a row of eight LEDs, the LEDs to be turned on and off for a round or cycle may be specified by the “vector” [01010111] with “0” denoting an “off” state and “1” denoting an “on” state. In alternate embodiments, other manners of specification as well as other manners of providing the specification may be employed instead. Further, as before, the intensity/brightness as well as color (in the case of multi-color LEDs) may be specified. 
     The above described approaches are just two exemplary approaches where a visualization agent may request visualization controller  1112  to selectively activate and deactivate LEDs  1114  on its behalf. Further, agents  1104 – 1108  are provided in the illustrated embodiment to facilitate the effectuation of the desired visualizations, such that the desired visualizations may be achieved without requiring or merely requiring relatively small amount of modifications to the main line logic or operational components of wireless mobile phone  1100 . However, in embodiments where the earlier described “request” interface of visualization controller  1112  is practiced, the visualization services offered by visualization controller  1112  may also be directly invoked by the other components of wireless mobile phone  1100  instead, should direct incorporation of the required logic into these other components of wireless mobile phone  1100  to practice the present invention be desirable. Thus, generically, a visualization requester, whether it is an “intervening” agent like visualization agents  1104 – 1108  or a functional “principal” (such as the component responsible for incoming call notification), may be referred to as a visualization “client”. 
     Referring now to  FIGS. 2   a – 2   b , wherein the relevant operational flows of visualization controller  1112  and agents  1104 – 1108  for practicing the present invention, in accordance with two embodiments, are shown, respectively. As illustrated in  FIG. 2   a , upon receipt of a request to selectively activate or deactivate selected ones of LEDs  1114  in selected manners, block  1202 , visualization controller  1112  determines if the request is of the first type (i.e. a single round request type), or of the second type (i.e. the multiple rounds/cycles request type), block  1204 . The distinction of the two types may be explicitly specified or implicitly inferred based at least in part on the format and/or substance of the calling parameters included with the function call. 
     If the request is determined to be of the first type (i.e. a single round request type), visualization controller  1112  activates and/or deactivates selected ones of LEDs  1114  as requested, block  1208 . If the request is determined to be of the second type (i.e. a multiple round/cycle request type), visualization controller  1112  activates and/or deactivates selected ones of LEDs  1114  as requested, block  1208 , after retrieving the “specification” for the activations/deactivations to be performed, block  1206 . For a multiple round request, the activation/deactivation operation of LEDs  1114  of block  1208  is iteratively performed for a sufficient number of times to achieve the selective activation/deactivation requested. 
       FIG. 2   b  illustrates the relevant operational flow of an exemplary visualization agent, which may be event, text or sound visualization agent  1104 ,  1106 , or  1108 , in accordance with one embodiment. As illustrated, at initialization, the agent performs one of a number of possible actions to ensure it is availed with the relevant information and/or data associated with the non-visual aspect of wireless mobile telephony it is responsible for. These possible actions include but are not limited to registering itself with an appropriate source or system service, such that it will be notified of or provided with the relevant information and/or data, or performing the necessary set up or re-direct such that it will be availed the relevant information and/or data. 
     For example, in an embodiment where the practiced visualizations include visualizing notice of an incoming call, at initialization, event visualization agent  1104  may register itself with a component of wireless mobile phone  1100  responsible for detecting an incoming call to notify it of such detection. Alternatively, event visualization  1104  may set itself up such that it can detect any attempt by the component to generate one or more rings for the incoming call. As those skilled in the art would appreciate, visualized notice of an incoming call is a particular useful alternative to the vibrational approach for a non-audible mode of operation, in lieu of the audible rings. Note that even for the non-audible mode of operation, the re-direct approach may nevertheless be effective if the component responsible for generating the audible rings will nevertheless make the attempts to generate the audible rings, and the attempts are merely “suppressed” (i.e. failed) or re-channeled to the component responsible for the vibrational notification, in view of the non-audible mode of operation. 
     Another example is for text visualization agent  1106  to register itself with or monitor the activities of the component responsible for rendering textual messages received in a non-audible call or the component responsible for rendering substantially textual (i.e. multi-media reduced) web pages. 
     Yet another example is for sounds visualization agent  1108  to register itself with or monitor the activities of the component (e.g. a microphone, a browser, a radio, a MPx or other media player of phone  1100 ) responsible for rendering audio contents or streaming audio. In one embodiment, the underlying system services include services for digitizing and providing digitized samples of audio. Upon registration with the service, sounds visualization agent  1108  receives the audio samples, and in response, determines the relevant attributes, such as volume, spectrum, and so forth, accordingly. The number of attributes analyzed and/or characterized is application dependent. Characterization of audio by attributes, such as volume, spectrum, treble, bass, and so forth, is known, and accordingly, will not be further described. 
     Continuing to refer to  FIG. 2   b , upon ensuring that it will be availed of the relevant information and/or data, the exemplary visualization agent awaits for provision or detection of the relevant information and/or data, block  1224 . Thereafter, upon receipt of or detection of the relevant information and/or data, the exemplary visualization agent determines if the visualization condition or conditions for the non-visual aspect of wireless mobile telephony it is responsible for are present, block  1224 . 
     For example, in the case of event visualization agent  1104 , it may consider the visualization condition is met upon having been notified by the component responsible for generating audible rings for incoming calls of the fact that an incoming call has been detected. In the case of text visualization agent  1106 , it may consider the visualization condition being met upon detecting a textual message of a non-audio call being rendered, or upon detecting the browser rendering non-graphics or substantially textual contents. In the case of sounds visualization agent  1108 , it may consider the visualization condition as being met, upon detecting a radio, a MPx or other media player rendering sounds, or a microphone picking up “meaningful” ambient sounds. Placing the wireless mobile phone in an operation state within which ambient sounds are considered meaningful, may be assisted by the user, e.g. via user prompt/confirmation. 
     Upon determining that one or more visualization conditions are met, the exemplary visualization agent determines the appropriate visualization for the detected condition or conditions, block  1226 . In various embodiments, the visualization to be effectuated under various visualization conditions are predetermined, and their exact nature are application dependent. 
     For example, in the case of event visualization agent  1104 , the predetermined visualization may involve requesting visualization controller  1112  to selectively activate and deactivate a row or column of LEDs  1114  to alert the user of an incoming call, or activate selected ones of LEDs  1114  to visualize the key stroking pattern corresponding to a menu selection made. This latter visualization is especially useful in teaching or familiarizing a user in selecting menu options through key stroking pattern (see co-pending &#39;197 application for further detail on menu selection through key stroking pattern). In the case of textual visualization agent  1104 , the predetermined visualization may involve requesting visualization controller  1112  to selectively activate and deactivate selected ones of LEDs  1114  to echo the corresponding Morse code representations of the alphanumeric characters of a textual message being rendered for a non-audible call, or selectively activate and deactivate selected ones of LEDs  1114  to render certain predetermined graphics of interest to supplement the non-graphics contents of a web page being rendered. The former visualization is also particularly useful in teaching or familiarizing a user to conduct a non-audible call using Morse code (see co-pending &#39;587 application for further detail on conducting a non-audible call using Morse code). The predetermined graphics for the latter visualization may be completely arbitrary or dependent on the presence of certain key words in the non-graphics contents. In the case of sounds visualization agent  1108 , the predetermined visualization may involve requesting visualization controller  1112  to selectively activate and deactivate selected ones of LEDs  1114  to render certain illumination patterns corresponding to certain predetermined attributes of the sound being rendered (e.g. its beat, tempo and so forth). The illumination to be rendered corresponding to the various attributes may be specified or stored in e.g. one or more audio visualization files. These specification files may be pre-provided, dynamically downloaded from a server, or retrieved from a storage medium integrated with an interchangeable covering of the mobile phone (also referred as “active” skin for certain embodiments, see the above identified co-pending application &#39;098 for further detail). The various attributes may be determined e.g. from samples derived from the audio stream of the integrated radio or MPx player. The sampling may be performed continuously. In other words, for such continuous sampling embodiment, attributes are determined periodically based on the obtained samples, and the illumination pattern is selected based on the determined attributes. This process of attribute determination and illumination pattern selection is repeatedly performed, e.g. for as long as sounds are being rendered (or until instructed by a user to terminate). 
     Upon determining the visualization, the exemplary visualization agent requests visualization controller  1112  to effectuate the desired visualization accordingly, block  1228 . Thereafter, the exemplary visualization agent returns to block  1224 , and continues from there as described earlier, until eventually operation of the exemplary visualization agent is terminated (for whatever reason, e.g. when phone  1100  shuts down). 
     Note that while the foregoing description suggests that event, text and sound visualization agents  1104 – 1108  may operate with substantially the same operational flow, in alternate embodiments, each or selected ones of visualization agents  1104 – 1108  may operate with substantially different operational flow instead. Further, the present invention may be practiced with more or less visualization agents. Regardless of the number of visualization agents provided, preferably, user selection facility is provided to enable a user to selectively and individually enable or disable each of the provided visualization agents. 
     Having now described the present invention from a function view, in particular, the various relevant operational flows, we turn now to describe various exemplary embodiments for disposing and configuring the various elements for practicing the visualizations of the present invention.  FIGS. 3   a – 3   b  illustrate an external view of a wireless mobile phone  1100   a , incorporated with the visualization teachings of the present invention, in accordance with one embodiment. More specifically,  FIG. 3   a  illustrates a side view of wireless mobile phone  1100   a , whereas  FIG. 3   b  illustrates a front view of wireless mobile phone  1100   a.

More importantly, wireless mobile phone  1100   a  includes LEDs  1114   a  disposed on a side exterior surface of the body of wireless mobile phone  1100   a . In one implementation, wireless mobile phone  1100   a  further includes a radio (not shown). In another, wireless mobile phone  1100   a  further includes a MPx player (not shown). 
     In alternate embodiments, LEDs  1114   a  may be disposed in other exterior surfaces of the body of the wireless mobile phone  1100   a  instead. These other exterior surfaces may include the top or bottom exterior surface, and the front or back exterior surface. Note that by virtue of the manner content is displayed in visual display  1324 , the exterior surfaces corresponding to the top, bottom, side, front and bottom surface are definitively defined. 
     For the illustrated embodiment, LEDs  1114   a  are disposed on the side exterior surface in a substantially columnar manner, along imaginary longitudinal axis  1311 . In alternate embodiments, LEDs  1114   a  may be arranged in other configurations, e.g. in multiples of even or uneven rows and/or columns. 
     In one embodiment, LEDs  1114   a  are single ed LEDs of the same color. In another embodiment, LEDs  1114   a  are single colored LEDs of different colors. In yet another embodiment, every three single colored LEDs of different colors (e.g. one Red, one Green, and one Blue) are grouped and proximately disposed together (e.g. each input key having one corresponding group of LEDs around it), functionally forming multiple 3-LED groups to facilitate manifestation of other non-basic colors, such as orange, yellow and so forth. In yet another embodiment, at least some of LEDs  1114   a  are multi-colored LEDs. A multi-colored LED is a LED that is capable of emitting light in a selected one of a plurality of colors.  FIGS. 4   a – 4   b  illustrate an exposed view of wireless mobile phone  1100   b , in accordance with an alternate embodiment. More specifically,  FIG. 4   a  illustrates an exposed front view of wireless mobile phone  1100   b  with its front cover  1421  removed, whereas  FIG. 4   b  illustrates an exposed interior (or backside) view of front cover  1421 . Front cover  1421  is also referred to as an interchangeable face plate. 
     Similar to the embodiments of  FIGS. 3   a – 3   b , wireless mobile phone  1100   b  includes speaker  1422 , visual display  1424 , input keys  1428 , microphone  1430 , and so forth. In one implementation, wireless mobile phone  1100   b  further includes a radio (not shown). Correspondingly, front cover (face plate)  1421  has “opening”  1423  for speaker  1422 , “opening”  1425  for visual display  1424 , “opening”  1427  for input keys  1428 , “opening”  1429  for microphone  1430 , and so forth. 
     More importantly, wireless mobile phone  1100   b  includes LEDs  1114   b  disposed on the interior front surface of wireless mobile phone  1100   b , near or around input keys  1428 . With front cover (face plate)  1421  in place, LEDs  1114   b  appear to be integrally disposed with input keys  1428 . In other words, for the illustrated embodiment, LEDs  1114   b  are disposed and configured as an array of light sources. In one implementation, front cover (face plate)  1421  further includes an electronic component (not shown) having stored therein, programming instructions implementing a MPx player. 
     Similar to the variants of the embodiment of  FIGS. 3   a – 3   b , LEDs  1114   b  may be single colored LEDs of the same color, or single colored LEDs of different colors. Further, in some embodiments, every three different color single colored LED, such as one Red, one Green and one Blue, may be grouped and proximately disposed together (e.g. each input key having one corresponding group of LEDs around it) to form groups of LEDs as earlier described. In yet other embodiments, at least some of LEDs  1114   b  may be multi-colored LEDs (where a selected one of a plurality of colors may be lit). 
     As will be described in more detail below, front cover (face plate)  1421  may be an “active” front cover/face plate having an electronic component wherein all or portions of the visualization teachings of the present invention are implemented. In particular, in various embodiments, “active” front cover (face plate)  1421  is an “active” covering “skin” covering all or a portion of the body of wireless mobile phone  1100   b . For these embodiments, instead of being disposed and configured on the interior front surface of wireless mobile phone  110   b , LEDs  1114   b  may be disposed on the exterior surface of the “active” interchangeable front cover (face plate) or covering “skin” instead. Active front cover (face plate) or covering “skin” is the subject matter of incorporated by reference application &#39;zzz. The constituting elements of these active front cover (face plate) or covering “skin” are described in details therein. Readers are referred to application &#39;zzz for details. 
       FIG. 5  illustrates an internal component view of wireless mobile phone  1100 , in accordance with one embodiment. As illustrated, wireless mobile phone  1100  includes the earlier mentioned microprocessor  1503 , transmitter/receiver (TX/RX)  1513  (also known as transceiver), and so forth, coupled to each other as shown. Additionally, for the illustrated embodiment, wireless mobile phone  1100  further includes digital signal processor (DSP)  1502 , communication interface  1511 , and general-purpose input/output (GPIO)  1515 , coupled to each other and to the earlier described elements as shown. Most importantly, wireless mobile phone  1100  includes LEDs  1114  and non-volatile memory  1510  having visualizer  1102   a  stored therein. 
     In addition to the conventional functions performed by these elements, the elements are employed to practice the visualization teachings of the present invention earlier described. In particular, among the conventional functions, it is expected that TX/RX  1513  may support one or more signaling protocols, including, but not limited to, code division multiple access (CDMA), time division multiple access (TDMA), global system for mobile communications (GSM), cellular digital packet data (CDPD), and so forth. Similarly, communication interface  1511  may support one or more serial, parallel and/or wireless communication protocols. 
     In alternate embodiments, other elements may be added, as well as having one or more of the illustrated elements omitted, without departing from the spirit and scope of the present invention. 
       FIG. 6  illustrates an internal component view of an “active” version of interchangeable “cover”  1421 , in accordance with one embodiment. As illustrated, “active” interchangeable “cover”  1421  includes in particular, electronic component  1620 . For the illustrated embodiment, interchangeable “cover”  1421  also includes LEDs  1114  (disposed and configured on an exterior surface). 
     In various embodiments, interchangeable “cover”  1421  may be a “housing cover”, i.e. being a part of a housing of the wireless mobile phone. In other embodiments, interchangeable “cover”  1421  may be an “accessory cover”, i.e. the “cover” is merely “adorned by the wireless mobile phone, and does not form a part of a housing of the wireless mobile phone. Thus, term “cover”, unless particularized, shall include “housing” as well as “accessory” covers. 
     In one embodiment, electronic component  1620  is a memory device, e.g. a subscriber identity module (SIM). In alternate embodiments, it may be a microprocessor having embedded memory. More importantly, for these embodiments, at least one or more of the visualization agents  1104 – 1108  are stored in the embedded memory. In various embodiments, the entire visualizer  1102 , including visualization controller  1112 , as well as agents  1104 – 1108  are stored in the embedded memory. In other words, for these embodiments, the visualization ability is additionally provided or partially provided to wireless mobile phone  1100  through the employment of an “active” interchangeable “cover”  1421  (i.e. face plate or covering skin), having embedded electronic component  1620  including all or a portion of visualizer  1102   b.    
     Thus, it can be seen from the above description, methods and apparatuses for supplementing wireless mobile telephony with visualization of various non-visual aspects of wireless mobile telephony to improve usability have been described. As mentioned earlier, while the present invention has been described in terms of the above-illustrated embodiments, the present invention is not limited to the embodiments described. The present invention can be practiced with modification and alternation within the spirit and scope of the appended claims. For example, in various embodiments, visualization of events may include visualization of an “idle” state. That is, upon detection of an “idle” state, a predetermined pattern of activation and deactivation of the LEDs may be effectuated. The predetermined pattern may correspond to a theme, e.g. a Christmas theme, an American theme, and the like. The predetermined pattern may be pre-provided, downloaded or retrieved from the integrated electronic component of an interchangeable cover plate (“active” skin). Thus, the description is to be regarded as illustrative instead of restrictive on the present invention.
