Title: Phone that prevents texting while driving

Description:
FIELD 
     Some embodiments are related to the field of wireless communication. 
     BACKGROUND 
     Many people use cellular phones in order to make and receive phone calls. For example, a user may utilize a cellular phone in order to talk with friends, stay in touch with family members, and transact business with co-workers and business associates while being away from the user&#39;s home or office. 
     Many users utilize a smartphone, which may include features of a cellular phone as well as features of a Personal Digital Assistant (PDA). For example, a smartphone may be used for placing and receiving phone calls, as well as for browsing the Internet, taking photographs by utilizing an integrated camera, playing games, sending and receiving electronic mail (email), maintaining a calendar or schedule, or the like. 
     SUMMARY 
     Some embodiments may include, for example, a phone that prevents, blocks and/or detects concurrent texting and driving, or texting while the phone user is seated in a vehicular driver&#39;s seat (e.g., and not in a vehicular passenger seat), or while the phone user is seated in a vehicular driver&#39;s seat while the vehicle is moving. 
     Some embodiments may prevent, block, eliminate, reduce and/or report occurrences of texting-while driving, mailing-while-driving, browsing the Internet while driving, or performing other unsafe and/or illegal phone-related operations while driving, or while seating in a driver&#39;s seat of a moving vehicle. 
     Some embodiments may include, for example, a phone able to detect or determine that a user of the phone is sitting in a driver seat of a moving vehicle. The determination may be based on, for example, captured front-side images, captured back-side images, captured audio or speech, contextual analysis of textual messages, contextual analysis of phone conversations or intra-vehicular conversations, contextual analysis of a thread of messages, GPS data or other location data, and/or other parameters which may be fused or weighted. 
     Upon such determination, the phone may block one or more features or applications, such as texting, messaging, composing messages, emailing, browsing the Internet, typing, or other features or applications. 
     Some embodiments may reduce, eliminate or block occurrences of concurrent texting-and-driving; may automatically penalize or report a phone user who concurrently drives-and-texts; and/or may automatically reward a phone user who continuously refrains from concurrent texting-and-driving. 
     Some embodiments may provide other and/or additional benefits and/or advantages.

     DETAILED DESCRIPTION OF SOME EMBODIMENTS 
     In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of some embodiments. However, it will be understood by persons of ordinary skill in the art that some embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, units and/or circuits have not been described in detail so as not to obscure the discussion. 
     The term “phone” as used herein may include, for example, a cellular phone, a cellphone, a smartphone (e.g., Apple iPhone, an Android-based smartphone or device, a Blackberry device, a Microsoft Windows based smartphone), a cordless phone (e.g., typically used in homes), a DECT phone, a mobile phone, a corded phone, a wireless communication device, or the like. Optionally, the term “phone” may include, for example, a tablet (e.g., Apple iPad, Motorola Xoom), a tablet computer, a tablet device, a handheld device, a portable device, an electronic device, a portable electronic device, an electronic book reader or e-book reader (e.g., Amazon Kindle, Barnes &amp; Noble Nook), a device able to send and/or receive phone calls, a device able to send and/or receive text messages and/or SMS messages and/or MMS messages and/or Instant Messages, a gaming device, a portable or handheld gaming device (e.g., Sony PlayStation Portable), or the like. 
     Some embodiments may include, for example, a phone which prevents its user from performing one or more operations via the phone, while the user is seated in a vehicular driver seat; or, while the user is seated in a driver seat of a moving vehicle or of an accelerating vehicle or of a decelerating vehicle. 
     The inventors have realized that in it may not suffice to merely estimate that a phone is located within a moving vehicle, in order to block or disallow one or more features of the phone (e.g., texting or emailing); as this approach may often result in a “false positive”, in which a vehicular passenger (who is not the vehicular driver) may be incorrectly blocked or prevented from using such features in the passenger&#39;s phone, even though the passenger is not driving or operating the vehicle. The inventors have realized that in order to eliminate such “false positives”, and in order to provide an effective solution that prevents, reduces or eliminates the unsafe and/or illegal practice of texting-and-driving or emailing-and-driving or browsing-and-driving, it may be beneficial and advantageous to determine whether or not the phone is utilized by a driver or by a non-driver (e.g., passenger) in a moving vehicle. 
     The phone may be able to automatically and/or autonomously determine: whether or not the phone user is within a vehicle; and/or whether or not the phone user is seated in a driver seat of a vehicle; and/or in which seat of a vehicle the phone user is seated; and/or in which seat of a vehicle the phone user is surely not seated; and/or in which row of a vehicle (e.g., front row or back row; or front row, second row, third row) the phone user is seated; and/or in which row of a vehicle the phone user is surely not seated; or the like. 
     For example, the phone may automatically and/or autonomously capture one or more photographs and/or videos, by using a front-side camera or front-facing camera of the phone, and/or by using a back-side camera or back-facing camera of the phone. Based on an analysis of the captured photographs and/or videos, the phone may reach the above-mentioned determination(s). 
     The phone may capture photographs and/or video periodically (e.g., every 30 seconds); or, upon occurrence of a predefined triggering event, for example, upon the user opening or launching a texting application or an email application or a “contacts” application; or upon performance by the user of one or more gestures and/or commands, or upon receiving a user command to compose a new text message or to compose a new email message, or to respond to a text or email message. 
     In some embodiments, the phone may reach one or more of the above-mentioned determination, about the particular seating of the phone user within a vehicle, by analyzing captured photographs and/or videos and recognizing or determining a location and/or a size (or, a relative location, a relative size, a slanting, a position, a relative position, or the like) of, for example: a vehicular steering wheel; a vehicular front window or windshield; a vehicular back window or windshield; a vehicular left-door front-side window or windshield; a vehicular right-door front-side window or windshield; a vehicular left-door backrow-side window or windshield; a vehicular right-door backrow-side window or windshield; a vehicular rear window or windshield; a vehicular left-side side-mirror; a vehicular right-side side-mirror; a vehicular internal mirror typically located at the top center of the front windshield; a vehicular stick-shift or gear-shift (which may be manual and/or automatic); a vehicular clock or watch; a vehicular speedometer; a vehicular gas meter or fuel meter; a vehicular dashboard; one or more vehicular air conditioning outlet(s); one or more vehicular air conditioning control buttons; one or more buttons or components (e.g., disk tray or disk slot) of a vehicular music player or a vehicular audio player or a vehicular CD player (which is typically located front-right to the driver seat) or a vehicular DVD player or a vehicular screen or monitor; a vehicular screen or monitor which displays the field-of-view captured by a vehicular camera facing the back (e.g., typically used when the vehicle is in Reverse and/or moving backwards); a vehicular dashboard component, for example, a button, a stick, a warning message, a notification message; a vehicular gas pedal and/or brake pedal and/or clutch pedal; a vehicular hand-brake; a vehicle manufacturer logo or name which may appear on a vehicular steering wheel; a vehicular seat or head-rest or cushion; vehicular components that are typically located on the internal side of a driver-side door (e.g., four buttons that control four windows of the vehicle; a button that locks all doors; a button that locks all windows); vehicular components that are typically located on the internal side of a passenger-side door (e.g., a singular window control button); vehicular components that are typically located on a vehicular steering wheel (e.g., cruise control buttons or components; steering wheels buttons that control the vehicular audio player or music player or CD player); and/or other vehicular items or components. 
     The phone may be able to automatically and/or autonomously determine: whether or not the user is within a vehicle; and/or whether or not the vehicle is moving; and/or whether or not the vehicle is static or stationary or non-moving or parked; and/or whether or not the vehicle is accelerating; and/or whether or not the vehicle is decelerating; and/or whether or not the vehicular engine is running. 
     For example, the phone may automatically and/or autonomously utilize location-based or location-aware components or modules of the phone, such as, a Global Positioning System (GPS) component or receiver or transceiver or module; and/or location information provided by a cellular network operator; and/or location information that the phone is able to obtain from other sources (e.g., wireless network(s), Wi-Fi network(s), Wi-Max network(s), cellular network(s), or the like). Based on multiple location readings or location data, the phone may deduce that the vehicle is generally moving; for example, if at time 8:12:34 AM the phone was located at a particular geo-spatial location, and at 8:12:36 AM the phone was located at another geo-spatial location which is approximately 34 meters away from the previous geo-spatial location, thereby indicating movement, or rapid movement that is not typical of a pedestrian walking (or, is at a speed which is impossible for a pedestrian to reach) but rather is more typical of a rapidly-moving car or of a moving car. 
     In other embodiments, the phone may automatically and/or autonomously determine the above-mentioned conclusions about movement of the phone (and a vehicle in which the phone is located) by using data from an accelerometer of the phone. For example, the accelerometer of the phone may indicate that the phone accelerates or decelerates, in general, or in particular rates that are more typical of a vehicle and are less typical (or are impossible) for a pedestrian or even a running person. 
     In some embodiments, once the user requests to compose, or while the user is composing, a text message or an email message or other type of message or communication, the phone may automatically and/or autonomously capture one or more photographs and/or videos, using the front-facing camera and/or the back-facing camera of the phone. 
     The phone may automatically and/or autonomously determine that a photograph, captured by the back-facing camera of the phone, includes a steering wheel (or a portion thereof; or another vehicular component) shown from an angle that is typical only if the phone user is seated in the driver seat, and not in a non-driver seat of the vehicle. For example, a back-facing camera of a phone, held by a vehicular driver, may capture a photographs which clearly shows the steering wheel (or portions thereof) up-close, or occupying a significant portion or percentage of the captured photograph or field-of-view (e.g., over 50 percent thereof), or showing the steering wheel directly in front of the camera that took the photographs. In contrast, a back-side camera of a phone, that is held by a passenger seating in the front row of the vehicle but not in the driver seat, may not show the steering wheel at all; or may show it from a distance and thus at an angel, or may show it slanted or at the side of the photograph. Similarly, a back-side camera of a phone, that is held by a passenger seating in the back row of the vehicle, may not show the steering wheel at all; or may show it from a distance and thus at an angel, or may show it slanted or at the side of the photograph, or the like. 
     Other vehicular components, or “anchors”, may be used by the phone for image analysis and/or video analysis. For example, a photograph captured by the back-side camera of the phone, may clearly show the speedometer, or the gas meter or fuel meter, or the left-side of the stick-shift, or the dashboard indicator which shows which gear is used (e.g., “D” for Drive or “P” for “Park”); and the phone may thus determine that the user of the phone is seated in a vehicular driver seat. 
     In some embodiments, photographs and/or videos captured by a front-facing camera of the phone may be used for analysis in order to determine the seating of the phone user, or in order to determine whether or not the phone user is seated in the driver seat. For example, a photograph or video captured by a front-facing camera of the phone may show a user having a buckled-up seat-belt which covers a portion of the right side of the user&#39;s shoulder, thereby indicating that the user is seated on a right side of the vehicle and not on the left side. Optionally, GPS information or other location information may indicate that the phone is located in the United States, such that a vehicular driver seat is on a left side of a vehicle (or, this information may otherwise be configured or provided to the phone, manually or automatically), thereby indicating that the phone user having the seat belt over his right shoulder is not the driver of the vehicle (but rather, either a front-row right-side passenger, or, a back-row right-side passenger). 
     In some embodiments, the analysis may take into account photographs and/or videos captured by both front-facing and back-facing cameras of the phone, in order to reach a correct conclusion, or in order to verify or reassure (or contradict, or deny) that the conclusion reached (or that a temporary conclusion or a candidate conclusion) is correct (or is incorrect). For example, a front-facing camera of the phone may capture a photograph showing the phone user having a seat-belt over his left shoulder; thereby indicating that the phone user is seated either in the driver seat, or in a back-row left-side seat, and thereby “eliminating” right-side passengers as possible phone users. In some embodiments, further narrowing-down and determination may be reached by taking into account another photograph or video, captured by the back-facing camera of the phone, which shows clearly a vehicular steering wheel (or a portion thereof), or which shows a vehicular speedometer: these vehicular components are typically not visible by a passenger seating in the left-side back row, behind the driver seat, as the driver seat and the driver typically block these vehicular components from being viewed by a left-side back-row passenger; and thus a determination may be reached that the phone user is seated in a vehicular driver seat. 
     In some embodiments, the image and/or video analysis may take into account images and/or footage that captures items or scenes or scene components that are extra-vehicular or external to the vehicle, for example, street view, trees, houses, other cars, or the like. For example, a front-row passenger may hold his phone in his right hand, such that the back-facing camera may clearly capture the right-side window of the front-right passenger door; and optionally, may even capture through that window an image of a nearby car in which another driver is shown, thereby indicating that the phone user is indeed a front-row passenger and not a driver. 
     In some embodiments, for example, the back-side camera may capture images and/or videos of vehicular traffic, which is facing the phone, or which travels downward in the video or towards the phone. Such captured images and/or videos indicate that the vehicular traffic captured is in the opposite direction to the current driving direction, and this may be more typical of images and/or videos captured by a driver-seat phone user who is closer (relative to a right-side front-row passenger) to opposite traffic which is typically on the left side of the vehicle. Similarly, for example, the back-side camera may capture images and/or videos of vehicular traffic, which is facing or moving away from the phone, or which travels upward in the video or away or ahead of the phone. Such captured images and/or videos indicate that the vehicular traffic captured is in the same direction to the current driving direction; and this, optionally together with other data (e.g., location or shape or angel of window frame, or seat-belt direction) may be used in order to determine whether or not the phone user is seated in a vehicular driver seat. 
     In some embodiments, a weighted system or a point-based system may be used in order to reach such determination. For example, in order to reach a conclusion that the phone user is in a driver seat, at least 20 points need to be accumulated by the phone&#39;s analysis module. In some embodiments, a photograph captured by the back-side camera of the phone, which clearly shows a large and significant and direct image of a vehicular steering wheel, may be associated with 25 points. In some embodiments, a partial image of a steering wheel may be associated with 10 points. In some embodiments, a clear image of a speedometer may be associated with 8 points. An image of driver&#39;s door components (e.g., four control buttons that control all windows in the car) may be associated with 15 points, or with 24 points. Analysis of one or more photographs and/or videos may thus aggregate points, and may reach a determination or conclusion accordingly. 
     Optionally, some identified image components or video components may contribute negative points. For example, a clear and direct image of a vehicular glove compartment (in a closed position, or in an open position), may be associated with a value of −15 (negative fifteen) points or −23 (negative twenty three) points. Similarly, a photograph or video captured by a front-side camera of the phone, showing a seatbelt over the right shoulder of the phone user, may have a value of −16 points, or a value of −22 points, or the like. 
     In some embodiments, one or more identified components may be associated with a prevailing weight, or other type of overriding value or weight, which forces the analysis to reach a particular conclusion. For example, in some embodiments, a front-side photograph which clearly shows the phone user having a seatbelt over his right shoulder and not over his left shoulder, may be a prevailing factor or criterion which necessarily reaches a conclusion that the phone user is not seated in a vehicular driver seat; and this determination may be held even if other image components, such as, visibility of portions of the dashboard and/or steering wheel and/or audio player, might have indicated towards an opposite conclusion (namely, that the phone user may be seated in the driver seat). 
     In some embodiments, the phone may utilize analysis (e.g., contextual analysis) of typed text and/or typed messages and/or typed communications (e.g., email messages), in order to determine that the phone user is seated in a driver seat and/or in a moving vehicle. For example, the phone use may compose a text message or an email, e.g., by typing on a virtual keyboard or an on-screen keyboard; by dictating speech that is converted to text; by swiping a finger over characters in a virtual or on-screen keyboard, or by pressing keys of a physical keyboard of the phone (e.g., integrated under the screen of the phone, or a “slider” sliding keyboard). The composed message may be, for example, “I am driving there right now, will be there in five minutes”. The phone may analyze the composed text, while it is being composed, or after it was composed but not yet sent out, or after it was composed and also sent out. The analysis may indicate that the phone user is currently driving in a vehicle; either by deducing this conclusion from the merits of the message, or optionally, by crossing such candidate conclusion with additional information, for example, GPS data or other location information which indicates that the phone is indeed moving (e.g., generally moving, or moving at a velocity that is indicative of a motor vehicle and not of a pedestrian). Upon reaching such conclusion, the phone may take one or more actions, for example, deny the sending out of the composed message (if it was not yet sent out); or deny further utilization of a texting or email application, for a pre-defined time (e.g., for ten minutes), or for a time-period deduced from the contextual analysis (e.g., for a period of five minutes, based on the composed message in which the user estimated that he will continue to drive for five more minutes), or until the phone determines that the user is no longer driving and/or moving (e.g., at all, or for a period of time, such as, for at least 45 seconds, or for at least 120 seconds; optionally by utilizing GPS data or other location data for such determination). 
     In some embodiments, the phone may monitor incoming and/or outgoing communications (e.g., textual communications, typed communications, uttered or spoken communications, or the like) for the purpose of such contextual analysis, which may optionally take into account a thread (or a portion of a thread) of multiple communications, and which may be used for determining whether or not the phone user is driving a vehicle and/or is within a moving vehicle. For example, a friend may send a text message (or email) to the phone user, at 4:37:05 PM, “Are you driving to me now?”; and the user may respond by text (or email), from the phone, at 4:37:18 PM, “Yes”. The contextual analysis of the phone may span a batch or thread of messages, in order to deduce that the phone user is driving a vehicle and/or is within a moving vehicle. 
     In some embodiments, the phone may monitor cellular phone conversations (e.g., between the phone user and a remote party with whom the phone user talks by utilizing the phone), in order to determine whether deduce that the phone user is driving a vehicle and/or is within a moving vehicle; or in order to deduce one or more parameters or data items which the phone may take into account for determining whether the phone user is driving a vehicle and/or is within a moving vehicle. For example, the phone may monitor in real time an ongoing cellular conversation; the phone may determine that the phone user (and not the remote party) uttered the phrase “I am now on my way to work” or “I am driving now to work”; may perform a contextual analysis which may indicate that the phone user, most probably, is in motion and/or is driving, based on the content of the uttered phrase; optionally, may cross the contextual analysis result with other data, for example, GPS data or location data which may indicate that the phone is moving (e.g., generally, or at a velocity indicative of a moving motor vehicle and not a pedestrian); and the phone may thus deduce that the phone user is driving a vehicle and/or is within a moving vehicle. 
     In some embodiments, the phone may monitor non-cellular conversations, for example, by capturing audio (e.g., ambient audio, background audio, or the like) using a microphone or other audio-capturing component of the phone. For example, the microphone of the phone may be activated autonomously and/or automatically by the phone, with or without letting the phone user know about the microphone activation; and the microphone of the phone may capture a background conversation between two or more person. Based on the level of the volume (and/or the pitch, and/or the tone, and/or other audio parameters) of the various spoken phrases and/or speakers, the phone may deduce that one speaker is probably the phone user (e.g., because his utterances sound louder, due to his proximity to his phone), whereas another speaker is probably a person who is not the user of that phone (e.g., because her utterances sound less loud, or more remote, due to her proximity from that phone). The phone may then convert the utterances from speech to text, and may perform contextual analysis on the text. For example, the phone may deduce that the person who is presumed to be the phone user, has just said to the other person, “we are almost there, let me just turn left on Cedar Lane”, or “We still have about ten minutes of driving, I now take the highway”, or “do you think that I should take the highway or the service road?”; and based on contextual analysis, the phone may deduce that the phone user is in motion and/or is driving, based on the content of the uttered phrase(s); optionally, the phone may cross the contextual analysis result with other data, for example, GPS data or location data which may indicate that the phone is moving (e.g., generally, or at a velocity indicative of a moving motor vehicle and not a pedestrian); and the phone may thus deduce that the phone user is driving a vehicle and/or is within a moving vehicle. 
     Once the phone deduces that the phone user is seating in a driver seat of a vehicle; or optionally, once the phone deduces cumulatively that the phone user is seating in a driver seat of a vehicle and that the vehicle is moving, then, the phone may take one or more actions, and/or the phone may prevent the phone user from performing one or more actions, and/or the phone may block or deny or un-authorize or disallow the phone user from performing one or more actions via the phone, and/or the phone may render some actions or features or applications unavailable to the phone user in whole or in part. For example, once the phone determines that the phone user is driving a moving vehicle, the phone: (a) may block the operation of a messaging application or module, a texting application or module, a typing application or module, a mapping application or module, a navigation application or module, an email application or module, a video conference application or module; and/or (b) may turn-off or deactivate one or more features of an application, for example, turning-off the “send” function of a texting application, or turning-off the option to compose a new message (e.g., while keeping operational the features of reading incoming messages); and/or (c) may turn-on or activate one or more features of an application, for example, turning-on a voice-recognition input method, optionally while deactivating a keyboard-dependent input method or a typing or swiping input method; and/or (d) may present or convey to the user a graphical and/or textual and/or voice warning or notification, indicating to the user that the phone is aware of the fact that the phone user is driving a moving vehicle, optionally indicating to the user that this feature is illegal and/or unsafe, and optionally warning the user that the currently-used function or application will no longer be available to the user (e.g., immediately, or within a pre-defined time period, or upon next attempt to use it) at all or until the vehicle is not moving (at all, or for at least 50 consecutive seconds); and/or (e) may force the phone user to perform one or more actions (e.g., exit a messaging application) in order to re-allow one or more applications or features of the phone; and/or (f) may create, modify and/or edit a logbook which keeps track of instances in which the phone deduced that the phone user was driving a moving vehicle while texting or emailing or typing on a phone (e.g., a logbook which keeps a time/date stamp for each such instance, indicating a start time and/or end time and/or other time points within such usage; optionally indicating the cumulative time per instance of such texting while driving; optionally indicating the particular application used by the phone user by driving; optionally indicating the identity of the party with whom the phone user communicated via texting while driving); and/or (g) may send a copy of that logbook, or may send an alarm or alert or notification, via texting or via email, to one or more pre-designated recipients (e.g., a parent or guardian or caregiver of the phone user; a manager or boss or supervisor or employer of the phone user; a law enforcement entity, e.g., a police department or a traffic police unit), optionally sending also to such recipient(s) an image of the phone user (e.g., captured by the front-facing camera of the phone); and/or (h) may allow the user to override the blocking of one or more phone features or phone applications, for example, by asking the user to confirm or re-confirm (e.g., by asking the user, while the user is texting a message, “It seems that you are driving and texting; are you sure that you would like to continue texting although it is unsafe and illegal?”, and allowing the user to respond with “Yes” via a voice command and/or by selecting a “yes” button), or by asking the user to type in or to utter a pre-defined overriding password or Personal Identification Number (PIN) or passphrase, or the like. 
     In some embodiments, the phone may deduce that the phone user is sitting in a driver seat of a moving vehicle (e.g., based on one or more parameters which may not necessarily include image analysis of a front-side camera image which may show a vehicular seat-belt); and the phone may deduce, based on a front-side camera image which shows the user without a seatbelt, that the user is not wearing a seatbelt. In some embodiments, in response to such determinations, the phone may present or convey to the phone user a message or notification or warning or question, using text and/or graphics and/or spoken text (e.g., pre-recorded message, or text-to-speech converted message), along the line of “Warning, I think that you are driving a car but your seatbelt is not buckled”, or, “Hey, not only are you driving and texting, you are not even buckled-up with your seatbelt!”. 
     In some embodiments, the phone may have two (or more) types of access control mechanisms. A phone owner or a primate user (e.g., an employer or a parent) may have full access or non-restricted access, which may allow the phone owner to configure the phone such that the phone will monitor and automatically detect that a user of the phone is operating a vehicle while texting; and the phone owner may further define the particular features that are to be denied or allowed upon such detection (e.g., sending out of text messages; composing of a text message; composing of an email), the particular conditions for blocking or allowing certain features, the ability of a secondary user to override and unblock the features by confirming or by providing a password, or the like. In some embodiments, a non-owner user, or a secondary user (e.g., a minor, a teenager, an employee), may have partial access or restricted access, which may allow such user to utilize the phone subject to the limitations or conditions set forth by the primary user, and which the secondary user may not be able to modify and/or override. The phone may enforce on the secondary user, the limitations placed by the primary user. Optionally, the phone may send a notification to a recipient designated by the primary user, by using a delivery means designated by the primary user (e.g., email, text message, voice message), indicating that the secondary user of the phone performed certain operations (e.g., concurrently driving and texting). 
     In some embodiments, the phone may create, maintain, update and/or modify a log or logbook or list or database, which keeps tracks of occurrences of concurrent driving and texting. Optionally, notification about such occurrence(s), may be sent by the phone automatically to a pre-designated recipient (e.g., pre-designated by the primary user of the phone, and non-modifiable by the secondary user of the phone). Optionally, in some embodiments, a copy of the logbook, or a copy of a portion of the logbook (e.g., daily portion, weekly portion, monthly portion) may be sent by the phone to a pre-designated recipient (e.g., parent or employer of the phone user). 
     In some embodiments, the phone may autonomously initiate a process which entails negative monetary (or other) consequences to the phone user which the phone determines to be concurrently texting and driving. For example, a traffic police system or a court system may be automatically notified by the phone of such occurrence, and a monetary fine (or other sanction or penalty or punishment) may be automatically imposed on the phone user. Optionally, a cellular service provider or cellular network provider or cellular phone provider may be notified of such occurrence, and a monetary debit may be imposed on the cellular bill or cellular account of the phone user. 
     In some embodiments, the phone may autonomously initiate a process which entails positive monetary (or other) consequences (e.g., a payment, a reward, a prize, a credit, a statement credit) to the phone user which the phone determines as refraining from concurrently texting and driving (e.g., for a pre-defined time period, for example, for at least one hour, for at least one day, for at least three days, for at least a week, for at least a month, or the like). For example, the phone may determine that within a pre-defined time period, the phone has never deduced that the phone user has been concurrently driving and texting; and the phone may notify one or more recipients about such good and lawful behavior of the phone user. Such recipients may include, for example, a traffic police department, a court system, a cellular service provider, a parent or guardian, an employer, or the like. In some embodiments, the phone may automatically initiate a process in which an employer of the phone user pays a monetary prize (or provides another prize) to the phone user for refraining from concurrent driving-and-texting for such period of time. In some embodiments, the phone may automatically initiate a process in which a cellular provider the phone user pays to the user a monetary credit amount (e.g., a nominal or symbolic amount, or a significant amount), for refraining from concurrent driving-and-texting for such period of time; optionally, the monetary credit amount may be symbolic (e.g., a one-dollar credit prize for refraining from concurrent texting-and-driving for a period of seven consecutive days), and may optionally be accompanied with a congratulating message or other type of positive acknowledgement. 
     In some embodiments, some or all of the analysis operations and/or determinations and/or deducing operation described herein, or their processes or methods, may be performed exclusively within the phone and/or by the phone and/or internally by the phone, and may not involve or require any external processing by a unit or module external to the phone. In some embodiments, some or all of the analysis operations and/or determinations and/or deducing operation described herein, or their processes or methods, may be performed exclusively externally to the phone and/or by a remote server and/or by a cloud computing service and/or by a cellular base station and/or by other type of external or remote unit or device. In some embodiments, for example, images and/or audio and/or video and/or text messages and/or audio conversations, may be captured locally by the phone (e.g., using a front-side camera and/or a back-side camera and/or a microphone); may be processed locally by a processor within the phone, and/or, may be transmitted wirelessly to a remote server or remote processor for analysis or for additional analysis; and the remote server may send back wirelessly to the phone the results of the remote analysis. In some embodiments, both local and remote analysis may be used in combination. In some embodiments, a local analysis within the phone may be initially performed in order to determine whether a current usage scenario is a good candidate for determining a concurrent driving-and-texting; and if the local analysis results in the positive, such that indeed a good candidate is locally detected, than the captured data (or other data, or additional data, or newly-captured data) may be sent wirelessly by the phone for further processing at a remote server, for reassurance purposes or for performing the final determination. In some embodiments, substantially all the processing and determination of concurrent driving-and-texting may be performed remotely, externally to the phone, by a remote server; and the local phone may receive an incoming wireless signal indicating such concurrent driving-and-texting. 
     Some embodiments may be adjusted, modified and/or configured to operate particularly at night-time or in dark environments. For example, some embodiments may utilize a flash or other phone-based illumination, in order to capture photographs in the dark and then use such photographs for image analysis. Some embodiments may utilize, or may take into account, the luminosity or illumination or glow or ambient light that a vehicular dashboard produces at night-time or when it is dark; may utilize such dashboard illumination for image capturing purposes; and/or may utilize the fact that dashboard illumination is present in order to contribute to (or lead to) a determination that the phone user is seated in a vehicular driver seat. For example, in some embodiments, the phone may determine that the current local time is 9:45 PM (e.g., based on an internal clock of the phone, and/or based on a signal or other data received by the phone from a cellular service provider); may determine that most probably the environment is dark; may determine that the phone is moving at a speed of 48 kilometers per hour (e.g., based on GPS data or other location data); may deduce that, therefore, the phone user is located within a moving car; may assume that generally or typically a vehicular cabin is dark at night time when travelling at such velocity; may detect that the particular phone appears to be illuminated by a glow or illumination from the vehicular dashboard (e.g., based on light measurement or light detection, by a light meter or light sensor of the phone or of its camera(s) or other suitable component); and may thus determine that since the phone is not in the dark, that the phone is being held by a driver in a driver seat in proximity to the illuminated dashboard, and not by a passenger. Other suitable mechanisms may be used for dark or reduced-illuminations scenarios or environments or areas. 
     In some embodiments, the phone may operate as described herein without specific knowledge or awareness of the phone user to the fact that the phone may secretly or covertly be monitoring the user&#39;s operations, or may be secretly capturing audio and/or images or monitoring messages, speed of movement, location, or other parameters or functions. For example, a corporate supervisor may provide the phone to a driver of the corporation, with or without notifying such driver that the phone may be able to (secretly) perform one or more of the operations described herein.

     Reference is made to  FIG. 2A , which is a schematic illustration of an image  201  acquired by a back-side camera of a phone, by a user seated in a vehicular driver seat, in accordance with some demonstrative embodiments. Image  201  shows a portion of a vehicular dashboard  211  (or vehicular front panel, or vehicular interior), which is slanted diagonally, going from bottom-left to upper-right. This particular type and/or direction of slanting, occurs particularly in images captured by a back-side camera of a phone held by a user seated in a vehicular driver seat (e.g., a front left seat in the car, in North America); and does not occur in images taken from a passenger seat (e.g., a front-row passenger seat, or a back-row passenger seat). 
     Furthermore, a left-side portion of a vehicular air conditioning outlet  212  is visible in image  201 ; whereas a right-side portion of vehicular air conditioning outlet  212  is not visible in image  201 . This phenomena characterizes some images captured by a back-side camera of a phone held by a user seated in a vehicular driver seat (e.g., a front left seat in the car, in North America); and it does not occur in images taken from a passenger seat (e.g., a front-row passenger seat, or a back-row passenger seat). 
     Additionally, a left-side portion of a vehicular music player  213  is visible in image  201 ; whereas a right-side portion of vehicular music player  213  is not visible in image  201 . This phenomena characterizes some images captured by a back-side camera of a phone held by a user seated in a vehicular driver seat (e.g., a front left seat in the car, in North America); and it does not occur in images taken from a passenger seat (e.g., a front-row passenger seat, or a back-row passenger seat). 
     Furthermore, the left-side portion of vehicular air conditioning outlet  212 , and/or the left-side portion of vehicular music player  213 , may appear diagonally slanted in image  201 . This phenomena characterizes some images captured by a back-side camera of a phone held by a user seated in a vehicular driver seat (e.g., a front left seat in the car, in North America); and it does not occur in images taken from a passenger seat (e.g., a front-row passenger seat, or a back-row passenger seat). 
     Reference is made to  FIG. 2B , which is a schematic illustration of an image  202  acquired by a back-side camera of a phone, by a user seated in a vehicular front-row passenger seat, in accordance with some demonstrative embodiments. Image  202  shows a portion of the vehicular dashboard  211  (or vehicular front panel), which is slanted diagonally, going from bottom-right to upper-left. This particular type and/or direction of slanting, occurs particularly in images captured by a back-side camera of a phone held by a user seated in a vehicular front-row passenger seat (e.g., a front right seat in the car, in North America); and do not occur in images taken from a driver seat (e.g., a front-row left-side seat, in North America). 
     Furthermore, a right-side portion of vehicular air conditioning outlet  212  is visible in image  202 ; whereas a left-side portion of vehicular air conditioning outlet  212  is not visible in image  202 . This phenomena characterizes some images captured by a back-side camera of a phone held by a user seated in a vehicular front-row passenger seat (e.g., a front right seat in the car, in North America); and it does not occur in images taken from a driver seat (e.g., a front-row left seat). 
     Furthermore, a right-side portion of vehicular music player  213  is visible in image  202 ; whereas a left-side portion of vehicular music player  213  is not visible in image  202 . This phenomena characterizes some images captured by a back-side camera of a phone held by a user seated in a vehicular front-row passenger seat (e.g., a front right seat in the car, in North America); and it does not occur in images taken from a driver seat (e.g., a front-row left seat). 
     Additionally, the right-side portion of vehicular air conditioning outlet  212 , and/or the right-side portion of vehicular music player  213 , may appear diagonally slanted in image  202 . This phenomena characterizes some images captured by a back-side camera of a phone held by a user seated in a vehicular front-row passenger seat (e.g., a front right seat in the car, in North America); and it does not occur in images taken from a driver seat (e.g., a front-row left seat). 
     Reference is made to  FIG. 3 , which is a schematic illustration of an image  300  acquired by a back-side camera of a phone, by a user seated in a vehicular driver seat, in accordance with some demonstrative embodiments. Image  300  shows up-close portions of vehicular components that are typically visible mainly or exclusively (or, in their entirety) from the driver seat, and are shown in image  300  from a direct-facing point-of-view (e.g., the back-side camera of the phone is facing directly towards the steering wheel). For example, image  300  may include a portion of circumference  301  of the vehicular steering wheel; a portion of a center  302  of the vehicular steering wheel; a logo  303  of a vehicle manufacturer which typically appears on vehicular steering wheels (and does not appear, for example, on a passenger-side glove compartment); a graphical representation  304  (e.g., of a horn or a trumpet or a French horn or a honking device) indicative of the location of a vehicular horn; a cruise control button  305  (or set of buttons); a vehicular gear indicator  312  indicating which gear is being used (e.g., Parking, Neutral, Reverse, Drive); a vehicular speedometer  313  able to measure vehicular velocity; and/or other vehicular components or portions thereof (for example, a vehicular tachometer able to measure how fast a vehicular engine is running, for example, in Revolutions Per Minute (RPM); a vehicular gas meter (or other type of vehicular fuel gauge); a vehicular engine temperature meter; or the like). Detection and/or recognition of these vehicular components in image  300 , particularly in combination of two or more components, and particularly if the components are shown clearly and appear to be in proximity to the back-side camera that captured image  300 , may contribute or may lead to a determination that the phone is held by a user who is seated in a vehicular driver seat. 
     Reference is made to  FIG. 4 , which is a schematic illustration of an image  400  acquired by a back-side camera of a phone, by a user seated in a vehicular driver seat, in accordance with some demonstrative embodiments. Image  400  shows up-close portions of vehicular components that are typically visible mainly from the driver seat, and are shown in image  400  from an angular point-of-view. For example, image  400  may be captured by a back-side camera of a left-handed driver, who sits in the vehicular driver seat and holds the phone in her left hand. Image  400  may include, for example, four vehicular window control buttons  401 , which may be arranged in an array  402  or matrix of two-by-two buttons (e.g., two lines, two rows). 
     In accordance with some embodiments, this unique arrangement of window control buttons  401 , and this number of (four) window control buttons  401 , is typically exclusive to the driver&#39;s side-door and is not to be found in a passenger door (which may include less than four window buttons; typically, only one window button). In some embodiments, for example, in a luxury or accessorized vehicle, the right-side front may rarely or may optionally include such arrangement of four window control buttons  401 ; however, the direction of the slanting of such buttons  401  and/or array  402  may be used by the phone in order to determine whether the user of the phone sits in the left-side or the right-side of the front row of the vehicle. For example, if the phone user sits in the front-left seat (the driver seat, in the United States), then the slanting of the generally-rectangular components shown in image  400  (and also, the slanting of the diagonal line shown in image  400 ) may run from bottom-left to upper-right, as depicted in image  400 . In contrast, if the phone user sits in the front-right seat, then the slanting of the generally-rectangular components may run from bottom-right to upper-left. 
     Detection and/or recognition of these vehicular components in image  400 , particularly the matrix or array  402  of four window-control buttons  401 , and optionally with the particular direction of diagonal slanting depicted in image  400 , all of them optionally appearing clearly and in proximity to the back-side camera that captured image  400 , may contribute or may lead to a determination that the back-side camera of the phone is held by a user seated in a vehicular driver seat (front-left seat in North America). 
     Reference is made to  FIGS. 5A-5E , which are schematic illustrations of five images  501 - 505  acquired by a front-side camera of a phone, by a user seated in five different seats in a vehicle, in accordance with some demonstrative embodiments. 
     Each one of images  501 - 505  may show a portion of a human body  577 , for example, a head and/or neck and/or shoulders and/or chest and/or arms, or a combination of other body parts or body regions or portions thereof. Furthermore, each one of images  501 - 505  may show a portion of a vehicular interior area  555 , which may typically be white of off-white or grey or brown or beige or light-colored, or may have other one or more colors. 
     Image  501  depicts a demonstrative photograph captured by a front-side camera of a phone held by a user seated in a front-left vehicular seat (e.g., the vehicular driver&#39;s seat in most cars in the United States). In image  501 , the vehicular interior  555  appears above the human body  577  and also appears to the left of the human body  577 ; whereas a portion of the external environment or scenery  521  (which is external to the vehicle; and depicts a demonstrative cloud representing the sky or other extra-vehicular area or item or scenery) may be located to the right of the human body  577 . The external environment or scenery  521  captured in image  501  may be, for example, generally trapezoid or generally triangular, or may have other suitable shape, which may depend on the location of the vehicular front left-side window which is on the left side of the vehicular driver&#39;s seat. Furthermore, a handle  511  may hang near (or at) the ceiling of the vehicle, above the frame of the left-side front door, and may appear in image  501  to be (in whole, or partially) on the upper-right side of image  501 , or above and to the right of the human body  577 ; and handle  511  may appear to be non-slanted, or only slightly slanted (e.g., slanted by 5 or 10 or 15 or 20 or 25 degrees, relative to a horizontal base line of image  501  or relative to a shoulders line of human body  577 , the slanting being from lower-left towards upper-right). These characteristics of image  501 , by themselves, or in contradiction or being different from the characteristics of images  502 ,  503 ,  504  and/or  505 , may be used in some embodiments in order to contribute to, or to lead to, a determination that image  501  was captured by the phone while the phone was held by a user seated in a front-left seat of the vehicle. 
     Image  502  depicts a demonstrative photograph captured by a front-side camera of a phone held by a user seated in a front-right vehicular seat (e.g., the vehicular front passenger seat in most cars in the United States). In image  502 , the vehicular interior  555  appears above the human body  577  and also appears to the right of the human body  577 ; whereas a portion of the external environment or scenery  522  (which is external to the vehicle; and depicts a demonstrative cloud representing the sky or other extra-vehicular area or item or scenery) may be located to the left of the human body  577 . The external environment or scenery  522  captured in image  502  may be, for example, generally trapezoid or generally triangular, or may have other suitable shape, which may depend on the location of the vehicular front right-side window which is on the right side of the vehicular front-row right-side (passenger) seat. Furthermore, a handle  512  may hang near (or at) the ceiling of the vehicle, above the frame of the right-side front (passenger) door, and may appear in image  502  to be (in whole, or partially) on the upper-left side of image  502 , or above and to the left of the human body  577 ; and handle  512  may appear to be non-slanted, or only slightly slanted (e.g., slanted by 5 or 10 or 15 or 20 or 25 degrees, relative to a horizontal base line of image  501  or relative to a shoulders line of human body  577 , the slanting being from lower-right to upper-left). These characteristics of image  502 , by themselves, or in contradiction or being different from the characteristics of images  501 ,  503 ,  504  and/or  505 , may be used in some embodiments in order to contribute to, or to lead to, a determination that image  502  was captured by the phone while the phone was held by a user seated in a non-driver seat, or seated in a front-right seat of the vehicle. 
     Image  503  depicts a demonstrative photograph captured by a front-side camera of a phone held by a user seated in a left-side back-row (rear) vehicular seat (e.g., the vehicular passenger seat located directly behind the driver in most cars in the United States). In image  503 , the vehicular interior  555  appears mainly above the human body  577 ; and optionally, a thin portion or vertical portion of vehicular interior  555  may also appear to the right of human body  577 ; whereas one or more portions of the external environment or scenery  523  (which is external to the vehicle; and depicts a demonstrative cloud representing the sky or other extra-vehicular area or item or scenery) may be located, for example, to the right of the human body  577  (e.g., corresponding to scenery from the left-side back-row side-window) and/or to the left of the human body  577  (e.g., corresponding to scenery from the horizontally-elongated rear window of the vehicle). The external environment or scenery  523  captured in image  503  may be, for example, generally trapezoid or generally triangular on the left side of human body  577 , and may be generally triangular (or may resemble a quarter of a circle, or a quarter of an oval) on the right side of human body  577 , or may have other suitable shape(s), which may depend on the location of the vehicular window(s) relative to the passenger seating at the back-row left-side passenger seat. Furthermore, a handle  513  may hang near (or at) the ceiling of the vehicle, above the frame of the left-side back-row (passenger) door, and may appear in image  503  to be (in whole, or partially) on the upper-right side of image  503 , or above and to the right of the human body  577 ; and handle  513  may appear to be slanted, or significantly slanted (e.g., slanted by more than 10 degrees, or more than 15 degrees, or more than 20 degrees, or more than 25 degrees, or more than 30 degrees, relative to a horizontal base line of image  503  or relative to a shoulders line of human body  577 , the slanting being from lower-left towards upper-right). These characteristics of image  503 , by themselves, or in contradiction or being different from the characteristics of images  501 ,  502 ,  504  and/or  505 , may be used in some embodiments in order to contribute to, or to lead to, a determination that image  503  was captured by the phone while the phone was held by a user seated in a non-driver seat, or seated in a left-side back-row passenger seat of the vehicle. 
     Image  504  depicts a demonstrative photograph captured by a front-side camera of a phone held by a user seated in a right-side back-row vehicular seat (e.g., the vehicular passenger seat located furthest from driver in most cars in the United States). In image  504 , the vehicular interior  555  appears mainly above the human body  577 ; and optionally, a thin portion or vertical portion of vehicular interior  555  may also appear to the left of human body  577 ; whereas one or more portions of the external environment or scenery  524  (which is external to the vehicle; and depicts a demonstrative cloud representing the sky or other extra-vehicular area or item or scenery) may be located, for example, to the left of the human body  577  (e.g., corresponding to scenery from the right-side back-row side-window) and/or to the left of the human body  577  (e.g., corresponding to scenery from the horizontally-elongated rear window of the vehicle). The external environment or scenery  524  captured in image  504  may be, for example, generally trapezoid or generally triangular on the right side of human body  577 , and may be generally triangular (or may resemble a quarter of a circle, or a quarter of an oval) on the left side of human body  577 , or may have other suitable shape, which may depend on the location of the vehicular window(s) relative to the passenger seating at the back-row right-side passenger seat. Furthermore, a handle  514  may hang near (or at) the ceiling of the vehicle, above the frame of the right-side back-row (passenger) door, and may appear in image  504  to be (in whole, or partially) on the upper-left side of image  504 , or above and to the left of the human body  577 ; and handle  514  may appear to be slanted, or significantly slanted (e.g., slanted by more than 10 degrees, or more than 15 degrees, or more than 20 degrees, or more than 25 degrees, or more than 30 degrees, relative to a horizontal base line of image  504  or relative to a shoulders line of human body  577 , the slanting being from lower-right towards upper-left). These characteristics of image  504 , by themselves, or in contradiction or being different from the characteristics of images  501 ,  502 ,  503  and/or  505 , may be used in some embodiments in order to contribute to, or to lead to, a determination that image  504  was captured by the phone while the phone was held by a user seated in a non-driver seat, or seated in a right-side back-row passenger seat of the vehicle 
     Image  505  depicts a demonstrative photograph captured by a front-side camera of a phone held by a user seated in a center back-row vehicular seat (e.g., the vehicular passenger seat located in the back row, in the center thereof). In image  505 , the vehicular interior  555  appears mainly above the human body  577 ; whereas two portions  531  and  532  of the external environment or scenery (which is external to the vehicle; and depicts demonstrative clouds representing the sky or other extra-vehicular area or item or scenery) may be located, for example, to the left and to the right of the human body  577  (e.g., corresponding to scenery from the rear window of the vehicle). Image  505  is further characterized by the absence of a handle (e.g., similar to handles  511 - 514 ), which typically is not associated with a central rear seat in a vehicle. These characteristics of image  505 , by themselves, or in contradiction or being different from the characteristics of images  501 ,  502 ,  503  and/or  504 , may be used in some embodiments in order to contribute to, or to lead to, a determination that image  505  was captured by the phone while the phone was held by a user seated in a non-driver seat, or seated in a center-rear passenger seat of the vehicle. 
     Other suitable images may be captured, analyzed and/or processed in accordance with embodiments of the present invention. In some embodiments, for example, a clear and/or enlarged and/or noticeable appearance of an elongated rear window of a vehicle, visible immediately behind a human body or a human face, in a photograph or image or video captured by the front-side camera of the phone, may lead or may contribute to a determination that the user of the phone seats in a non-driver seat or in a back row seat or in a back seat or in a passenger seat of the vehicle. Other suitable image characteristics may be used or may be taken into account. 
     Reference is made to  FIGS. 6A and 6B , which are schematic illustrations of two images  601  and  602  (respectively) acquired by a front-side camera of a phone, by a user seated in two different seats in a vehicle, in accordance with some demonstrative embodiments. 
     Each one of images  601 - 602  may show a portion of a human body  677 , for example, a head and/or neck and/or shoulders and/or chest and/or arms, or a combination of other body parts or body regions or portions thereof. 
     Image  601  shows a vehicular seatbelt  641  located on the right side of image  601 , crossing diagonally over the left shoulder of the human body  677 , and appearing under and to the right of the human face. These characteristics are typical of a vehicular user that sits in a left-side seat of the vehicle, such the seatbelt crosses over his left shoulder. 
     In contrast, image  602  shows a vehicular seatbelt  642  located on the left side of image  602 , crossing diagonally over the left shoulder of the human body  677 , and appearing under and to the left of the human face. These characteristics are typical of a vehicular user that sits in a right-side seat of the vehicle, such the seatbelt crosses over his right shoulder. 
     The location and/or direction of the seatbelt may contribute to, or may lead to, a determination whether or not the phone user sits in a driver seat or in a passenger seat. For example, if the front-side camera of the phone captures an image which appears to be similar to image  602  (and not to image  601 ), then the phone may determine that the phone user sits on a right-side seat and thus is not the driver (of a vehicle in which the driver seat is on the left side, such as in the United States). 
     In some embodiments, a front-facing camera of the phone may capture an image of the user, which indicates that the user is below (or significantly below) a driving age. For example, the front-facing camera of the phone may capture an image of a child who clearly appears to be around eight or nine or ten years old. The phone may utilize an algorithm able to estimate the age, or age group or age range, of a pictured user (or pictured user&#39;s face), and may thus determine that the phone user clearly may not be the driver, due to his or her young age. Optionally, a user age estimator, or user age-range estimator, may be included in the phone. In some embodiments, the phone may take into account, for determining or estimating the age (or age range) of the user, one or more information items (e.g., date-of-birth, age, age range) that the user entered or supplied online or at Internet websites or to other applications (e.g., when checking-out at an online shopping process or website; when filling-out a personal profile of the user for a social network or for a web-mail account). 
     In some embodiments, the phone may estimate, determine, and/or take into account a speed (or rate) of texting or typing, as part of the analysis or decision-making process. For example, the phone may determine that the phone user typically types text at a rate of approximately 80 characters per minute; or that the phone user typically types text at a rate of 77 characters per minute when the phone is generally stationary and non-moving; whereas, the user of the phone is currently typing or entering text at a significantly slower pace or lower rate, for example, less than 50 percent or less than 40 percent or less than 30 percent or less than 25 percent than the user&#39;s typical speed or rate; optionally, together with identifying that the phone is currently moving at a speed of 48 miles per hour (e.g., based on GPS data or other location data). This may indicate that the phone user, who is typing significantly slower now, is probably driving a moving vehicle. In some embodiments, the phone may identify or take into account a stop or pause in typing (or in entering text), similarly pointing towards the possible determination that the user of the phone is driving while texting; particularly if such pauses or stops are not typical of that phone user in other scenarios (e.g., when the phone is substantially non-moving). 
     In some embodiments, the phone may take into account the location of one or more transmitters or illumination units which may be placed within a vehicle in order to assist the phone in determining whether or not the phone user is seated in the driver seat. For example, in some embodiments, a small red light may be installed at the vehicular ceiling over the driver seat, and a small green light may be installed at the vehicular ceiling over the front passenger seat. The phone may determine that it is closer to the red light, and thus the phone user sits in the driver seat. In other embodiments, multiple wireless transmitters or wireless transceivers may be installed within the car, in fixed or non-changing locations; and the phone may utilize a wireless receiver or a wireless transceiver of the phone in order to triangulate its position relative to such vehicular transmitter, and thereby determine the intra-vehicular position of the phone. 
     Some embodiments may be used by an enterprise, a corporate entity, a retailer, a trucking company, a moving company, a corporation that has a fleet of vehicles, a deliver company, a shipping company, or the like. For example, a shipping company may utilize some embodiments of the invention across most or all of the phone utilized by drivers of the shipping company; and may advertise that “We put safety first; all our drivers are equipped with cellular phones that prevent texting and driving”. A supervisor within company may receive occurrence logs from all phones associated with the vehicular fleet of the company; may take disciplinary actions against drivers that are reported (by their phones) as performing unsafe and/or illegal operations (e.g., texting, emailing, browsing the Internet) while driving or while operating their vehicles; and may reward drivers who have a “clean” log of such unsafe and/or illegal occurrences. 
     Portions of the discussion herein may relate, for demonstrative purposes, to a “vehicular driver seat” or “vehicular driver&#39;s seat” under the assumption that such driver seat is located in the front-left side of a car or vehicle, as common in the United States or in most countries worldwide. However, the present invention may be used, with the suitable adjustments or modifications, to a vehicular driver seat which may be located in the front-right side of the car or vehicle, as common in the United Kingdom and other countries. It would be appreciated that some embodiments, which take into account right-side or left-side parameter or images or considerations, may be adjusted to such countries, for example, by flipping or substituting left-for-right and right-for-left, or by using a “mirror” image rather than a plain-captured image, or the like. In some embodiments, a phone may be able to autonomously and/or automatically recognize that the phone is being used in the United Kingdom or in other countries or regions in which a driver seat is typically in the front-right side of the cabin within a vehicle, for example, based on GPS data or other location data; and may automatically adjust or modify or configure its settings to perform the analysis based on flipped or mirrored images or considerations. In some embodiments, the phone user may indicate, or may be asked by the phone, in which country the phone is being used, and adjustments may be made accordingly. In some embodiments, similar adjustments may be made, regardless of the geographical location or country, for special vehicles in which the driver seat may be located in the front-right side of the vehicle; for example, in some types of delivery trucks, in some models of United States Postal Service mail delivery trucks, or the like. 
     Some portions of the discussion may relate, for demonstrative purposes, to detection, prevention, blocking and/or elimination of driving-and-texting. However, the present invention may be used in conjunction with detection, prevention, blocking and/or elimination of other operations which may be unsafe and/or undesired and/or illegal, for example, emailing-and-driving, utilizing a navigation application and driving, composing text and driving, gaming and driving, playing a game on a phone and driving, browsing the Internet and driving, downloading a file and driving, capturing photographs and/or video while driving, or the like. 
     Furthermore, the term “driving” as used herein may include any suitable verb or operation or functionality which may be performed or utilized by a driver or a vehicle operator, and may or may not include causing the vehicle to drive or to move. For example, the term “driving” may include steering, changing lanes, braking, slowing down, accelerating, decelerating, stopping, parking, driving forward, driving backward, driving in reverse, shifting gear(s), operating machinery or heavy machinery (e.g., in a tractor, bulldozer, crane, truck, dump-truck, garbage truck, or the like), performing auxiliary operations (e.g., receiving trip fare by a bus operator or taxi driver, dispensing monetary change by a bus operator or taxi driving, producing and/or giving a receipt or a ticket by a bus operator or a taxi driver), and/or other suitable operations. 
     Although portions of the discussions herein may relate, for demonstrative purposes, to a phone or cellular phone or smartphone able to block or restrict one or more of its features (e.g., texting, emailing, messaging, browsing) upon detecting that its user is driving a vehicle, some embodiments of the present invention may include other types of devices, electric devices, electronic devices, portable devices, or the like. Such devices may include, for example, portable electric or electronic devices, a portable gaming device, a handheld gaming device, an electric shaver, an e-book reader or electronic book reader, a personal organizer or PDA device, or other suitable devices. 
     Discussions herein utilizing terms such as, for example, “processing,” “computing,” “calculating,” “determining,” “establishing”, “analyzing”, “checking”, or the like, may refer to operation(s) and/or process(es) of a computer, a computing platform, a computing system, or other electronic computing device, that manipulate and/or transform data represented as physical (e.g., electronic) quantities within the computer&#39;s registers and/or memories into other data similarly represented as physical quantities within the computer&#39;s registers and/or memories or other information storage medium that may store instructions to perform operations and/or processes. 
     The terms “plurality” or “a plurality” as used herein include, for example, “multiple” or “two or more”. For example, “a plurality of items” includes two or more items.
