In at least one example embodiment, the camera module may further comprise a processing element such as a co-processor that assists the processor  11  in processing image data and an encoder and/or decoder for compressing and/or decompressing image data. The encoder and/or decoder may encode and/or decode according to a standard format, for example, a Joint Photographic Experts Group (JPEG) standard format. 
       FIGS. 2A-2D  are diagrams illustrating grip surfaces according to at least one example embodiment. The examples of  FIGS. 2A-2D  are merely examples of grip surfaces of an apparatus, and do not limit the scope of the claims. For example, shape of the apparatus may vary, holding configuration of the apparatus may vary, and/or the like. 
     Many electronic apparatuses are configured to be held by a user. For example, the apparatus may be a mobile phone, a tablet, a personal digital assistant, a camera, a video recorder, a remote control unit, a game console, and/or the like. Such apparatuses may be configured such that surfaces of the apparatus are associated with holding the apparatus. In at least one example embodiment, a surface of the apparatus that is configured to be held by a user is referred to as a grip surface of the apparatus. For example, the apparatus may be designed such that holding the apparatus is facilitated by one or more grip surfaces of the apparatus. For example, the apparatus may be shaped to allow a user to hold the apparatus from the sides of the apparatus, the back of the apparatus, and/or the like. In at least one example embodiment, a surface in which holding the apparatus may cause contact with the apparatus is referred to as a grip surface of the apparatus. For example, even though an apparatus may be configured to be held by a single hand at grip surfaces on opposite sides of the apparatus, the back surface of the apparatus may be contacted by the hand due to the hand holding each side of the apparatus. In this manner, the back of the apparatus may be a grip surface of the apparatus. 
     The apparatus may have one or more grip surfaces. For example, the user may contact one or more surfaces of the apparatus as a result of holding the apparatus. For example, a grip surface of the apparatus may be at least part of one or more edges of the apparatus, at least part of a back surface of the apparatus, at least part of a handle of the apparatus, and/or the like. In at least one example embodiment, an edge of an apparatus relates to a surface of the apparatus associated with a side of the apparatus, such as a left side, a top side, a bottom side, a right side, and/or the like. In at least one example embodiment, an edge may be characterized by way of being a surface that is neither a front surface nor a rear surface. In at least one example embodiment, a front surface of the apparatus relates to a surface of the apparatus configured to face towards a user when the apparatus is in use. For example, the front of the apparatus may comprise at least one primary display. In such an example, the primary display may be characterized by being the only display of the apparatus, the largest display of the apparatus, the most interactive display of the apparatus, and/or the like. In at least one example embodiment, the back surface of the apparatus is a surface of the apparatus that is opposite to the front surface of the apparatus. For example, the back surface may relate to a surface of the apparatus opposite to a surface associated with a primary display. 
       FIG. 2A  is a diagram illustrating grip surfaces according to at least one example embodiment. The example of  FIG. 2A  shows apparatus  202  being held in hand  204 . It can be seen that the right edge of apparatus  202  and the left edge of apparatus  202  are grip surfaces of apparatus  202 . In addition, hand  204  is contacting apparatus  202  at the back surface of apparatus  202  due to hand  204  holding apparatus  202 . In this manner, the back surface of apparatus  202  may be a grip surface of apparatus  202 . 
       FIG. 2B  is a diagram illustrating grip surfaces according to at least one example embodiment. The example of  FIG. 2B  shows apparatus  222  being held in hands  224  and  226 . It can be seen that the right edge of apparatus  222  and the left edge of apparatus  222  are grip surfaces of apparatus  222 . In addition, hands  224  and  226  are contacting apparatus  222  at the back surface of apparatus  222  due to hands  224  and  226  holding apparatus  222 . In this manner, the back surface of apparatus  222  may be a grip surface of apparatus  222 . 
     In some circumstances, an apparatus may be configured to be held in multiple orientations, in multiple holding configurations, and/or the like. For example, apparatus  222  may be the same apparatus as apparatus  202  of  FIG. 2A . For example,  FIG. 2A  may depict apparatus  222  being held at a different orientation than the example of  FIG. 2B . Therefore, more than two edges of apparatus  222  may be grip surfaces. For example, the apparatus may treat a surface as a grip surface even if the user is not currently holding the apparatus in a manner that holding the apparatus results in contact at the grip surface. 
       FIG. 2C  is a diagram illustrating grip surfaces according to at least one example embodiment. The example of  FIG. 2C  shows apparatus  252  being held in hand  254 . It can be seen that the right edge of apparatus  252  and the left edge of apparatus  252  are grip surfaces of apparatus  252 . In addition, hand  254  is contacting apparatus  254  at the back surface of apparatus  252  due to hand  254  holding apparatus  252 . In this manner, the back surface of apparatus  252  may be a grip surface of apparatus  252 . It can be seen that a finger of hand  254  is contacting apparatus  252  upward from the position at which hand  254  is contacting the surface of apparatus  252 . The user may be utilizing such finger position to control the angle of apparatus  252 , to stabilize apparatus  252 , and or the like. Therefore, even though such finger position may not be necessary for the apparatus to be supported by the user, the upper part of the back surface may be a grip surface by way of the apparatus being configured such that a user may place one or more fingers at the upper part of the apparatus to facilitate holding the apparatus in a desired manner. 
       FIG. 2D  is a diagram illustrating grip surfaces according to at least one example embodiment. The example of  FIG. 2D  shows apparatus  262  being held in hands  264  and  266 . It can be seen that the top edge of apparatus  262  and the bottom edge of apparatus  262  are grip surfaces of apparatus  262 . 
       FIGS. 3A-3E  are diagrams illustrating touch inputs according to at least one example embodiment. The examples of  FIGS. 3A-3E  are merely examples of touch inputs, and do not limit the scope of the claims. For example, number of inputs may vary, relationship between inputs may vary, orientation of inputs may vary, and/or the like. 
     In  FIGS. 3A-3E , a circle represents an input related to contact with a touch sensor, such as a touch display, two crossed lines represent an input related to releasing a contact from a touch sensor, and a line represents input related to movement on a touch sensor. Although the examples of  FIGS. 3A-3E  indicate continuous contact with a touch sensor, there may be a part of the input that fails to make direct contact with the touch sensor. Under such circumstances, the apparatus may, nonetheless, determine that the input is a continuous stroke input. For example, the apparatus may utilize proximity information, for example information relating to nearness of an input implement to the touch sensor, to determine part of a touch input. 
     It should be understood that, even though touch sensor information is described in terms of contact and release, many touch sensors may determine that a contact occurs when the user&#39;s hand is within a threshold distance from the apparatus, without physically contacting the apparatus. Therefore, contact may relate to circumstances where the touch sensor determines that proximity is sufficiently close enough to determine existence of contact. Similarly, release may relate to circumstances where the touch sensor determines that proximity is sufficiently distant enough to determine termination of contact. 
     In the example of  FIG. 3A , input  300  relates to receiving contact input  302  and receiving a release input  304 . In this example, contact input  302  and release input  304  occur at substantially the same position. In an example embodiment, an apparatus utilizes the time between receiving contact input  302  and release input  304 . For example, the apparatus may interpret input  300  as a tap for a short time between contact input  302  and release input  304 , as a press for a longer time between contact input  302  and release input  304 , and/or the like. 
     In the example of  FIG. 3B , input  320  relates to receiving contact input  322 , a movement input  324 , and a release input  326 . Input  320  relates to a continuous stroke input. In this example, contact input  322  and release input  326  occur at different positions. Input  320  may relate to dragging an object from one position to another, to moving a scroll bar, to panning a virtual screen, to drawing a shape, and/or the like. In an example embodiment, an apparatus interprets input  320  based at least in part on the speed of movement  324 . For example, if input  320  relates to panning a virtual screen, the panning motion may be small for a slow movement, large for a fast movement, and/or the like. In another example embodiment, an apparatus interprets input  320  based at least in part on the distance between contact input  322  and release input  326 . For example, if input  320  relates to a scaling operation, such as resizing a box, the scaling may relate to the distance between contact input  322  and release input  326 . An apparatus may interpret the input before receiving release input  326 . For example, the apparatus may evaluate a change in the input, such as speed, position, and/or the like. In such an example, the apparatus may perform one or more determinations based upon the change in the touch input. In such an example, the apparatus may modify a text selection point based at least in part on the change in the touch input. 
     In the example of  FIG. 3C , input  340  relates to receiving contact input  342 , a movement input  344 , and a release input  346  as shown. Input  340  relates to a continuous stroke input. In this example, contact input  342  and release input  346  occur at different positions. Input  340  may relate to dragging an object from one position to another, to moving a scroll bar, to panning a virtual screen, to drawing a shape, and/or the like. In an example embodiment, an apparatus interprets input  340  based at least in part on the speed of movement  344 . For example, if input  340  relates to panning a virtual screen, the panning motion may be small for a slow movement, large for a fast movement, and/or the like. In another example embodiment, an apparatus interprets input  340  based at least in part on the distance between contact input  342  and release input  346 . For example, if input  340  relates to a scaling operation, such as resizing a box, the scaling may relate to the distance between contact input  342  and release input  346 . In still another example embodiment, the apparatus interprets the position of the release input. In such an example, the apparatus may modify a text selection point based at least in part on the change in the touch input. 
     In the example of  FIG. 3D , input  360  relates to receiving contact input  362 , and a movement input  364 , where contact is released during movement. Input  360  relates to a continuous stroke input. Input  360  may relate to dragging an object from one position to another, to moving a scroll bar, to panning a virtual screen, to drawing a shape, and/or the like. In an example embodiment, an apparatus interprets input  360  based at least in part on the speed of movement  364 . For example, if input  360  relates to panning a virtual screen, the panning motion may be small for a slow movement, large for a fast movement, and/or the like. In another example embodiment, an apparatus interprets input  360  based at least in part on the distance associated with the movement input  364 . For example, if input  360  relates to a scaling operation, such as resizing a box, the scaling may relate to the distance of the movement input  364  from the contact input  362  to the release of contact during movement. In at least one example embodiment, the input of the example of  FIG. 3D  may be referred to as a swipe input, a flick input, and/or the like. 
     In an example embodiment, an apparatus may receive multiple touch inputs at coinciding times. For example, there may be a tap input at a position and a different tap input at a different location during the same time. In another example there may be a tap input at a position and a drag input at a different position. An apparatus may interpret the multiple touch inputs separately, together, and/or a combination thereof. For example, an apparatus may interpret the multiple touch inputs in relation to each other, such as the distance between them, the speed of movement with respect to each other, and/or the like. 
     In the example of  FIG. 3E , input  380  relates to receiving contact inputs  382  and  388 , movement inputs  384  and  390 , and release inputs  386  and  392 . Input  320  relates to two continuous stroke inputs. In this example, contact input  382  and  388 , and release input  386  and  392  occur at different positions. Input  380  may be characterized as a multiple touch input. Input  380  may relate to dragging an object from one position to another, to moving a scroll bar, to panning a virtual screen, to drawing a shape, to indicating one or more user selected text positions and/or the like. In an example embodiment, an apparatus interprets input  380  based at least in part on the speed of movements  384  and  390 . For example, if input  380  relates to zooming a virtual screen, the zooming motion may be small for a slow movement, large for a fast movement, and/or the like. In another example embodiment, an apparatus interprets input  380  based at least in part on the distance between contact inputs  382  and  388  and release inputs  386  and  392 . For example, if input  380  relates to a scaling operation, such as resizing a box, the scaling may relate to the collective distance between contact inputs  382  and  388  and release inputs  386  and  392 . 
     In an example embodiment, the timing associated with the apparatus receiving contact inputs  382  and  388 , movement inputs  384  and  390 , and release inputs  386  and  392  varies. For example, the apparatus may receive contact input  382  before contact input  388 , after contact input  388 , concurrent to contact input  388 , and/or the like. The apparatus may or may not utilize the related timing associated with the receiving of the inputs. For example, the apparatus may utilize an input received first by associating the input with a preferential status, such as a primary selection point, a starting position, and/or the like. In another example, the apparatus may utilize non-concurrent inputs as if the apparatus received the inputs concurrently. In such an example, the apparatus may utilize a release input received first the same way that the apparatus would utilize the same input if the apparatus had received the input second. 
     Even though an aspect related to two touch inputs may differ, such as the direction of movement, the speed of movement, the position of contact input, the position of release input, and/or the like, the touch inputs may be similar. For example, a first touch input comprising a contact input, a movement input, and a release input, may be similar to a second touch input comprising a contact input, a movement input, and a release input, even though they may differ in the position of the contact input, and the position of the release input. 
       FIGS. 4A-4D  are diagrams illustrating regions of a grip surface according to at least one example embodiment. The examples of  FIGS. 4A-4D  are merely examples of regions of a grip surface, and do not limit the scope of the claims. For example, position of a region may vary, shape of a region may vary, size of a region may vary, and/or the like. 
     In some circumstances, it may be desirable to provide a way for a user to perform input on a grip surface of the apparatus. For example, the user may desire to perform input using a hand that is holding the apparatus. 
     In some circumstances, it may be desirable to provide one or more mechanical input actuation devices on a grip surface of the apparatus. For example, it may be desirable to allow a user to perform input on such an actuator by performing actuation of the mechanical input actuation device using the hand that is holding the apparatus. In some circumstances, the physical characteristics of the mechanical input actuation device may be such that the mere holding of the apparatus does not cause actuation of the mechanical input actuation device. For example, actuation of the mechanical input actuation device may be associated with the user applying a greater amount of force to the mechanical input actuation device than the user applies for holding the apparatus. 
     In some circumstances, it may be desirable to provide a grip surface input device to a user absent utilization of a mechanical input actuation device. For example, the apparatus may utilize a touch sensor, such as a capacitive touch sensor, a resistive touch sensor, and/or the like. Without limiting the scope of the claims in any way, at least one technical effect associated with utilization of a touch sensor instead of a mechanical input actuation device may be to reduce amount of circuit board strain associated with user input, reduce cost of materials of an apparatus, reduce production complexity associated with housing, reduce production complexity associated with construction, and/or the like. In such an apparatus, the touch sensor may or may not correspond to a display. For example, the touch sensor associated with a grip surface of the apparatus may be a touch display, may not be a touch display, and/or the like. 
     In apparatuses that utilize one or more touch sensors for input at a grip surface of the apparatus, it may be desirable for the apparatus to differentiate inadvertent contact with the apparatus, for example contact associated with holding the apparatus, from input performed by the user. In at least one example embodiment, the apparatus provides for an intent designation input. An intent designation input may be an input that is indicative of a non-accidental touch input. For example, the intent designation input may be an input that is unlikely to be associated with contact resulting from holding the apparatus. For example, the intent designation input may be one or more inputs, such as a sequence of predetermined inputs. In at least one example embodiment, the intent designation input comprises a contact input, a release input, and another contact input that occur within a threshold time. For example, an indication of an input that is indicative of a user tapping and pressing a region of a grip surface may relate to an intent designation input. In at least one example embodiment, the intent designation input comprises two contact inputs occurring together. In at least one example embodiment, the apparatus determines that inputs occur together if the inputs occur within a concurrency time threshold of each other. A concurrency time threshold may relate to a time threshold indicative of a time interval at which a user may be unable to perceive a time difference between inputs. For example, an indication of an input that is indicative of two contact inputs occurring together may relate to an intent designation input. In at least one example embodiment, the intent designation input comprises two contact inputs occurring together, two release inputs occurring together, and two contact inputs occurring together within a threshold time. For example, an indication of an input that is indicative of a user tapping two fingers and pressing a region of a grip surface with the two fingers may relate to an intent designation input. 
     In at least one example embodiment, the apparatus receives an indication of a touch input that is associated with a region of a grip surface of the apparatus. The apparatus may receive the indication of the touch input from a touch sensor, from a device that receives touch sensor information, from a device that manages touch sensor information, and/or the like. The indication of the touch input may be any information that communicates occurrence of the touch input, identity of the touch input, one or more characteristics of the touch input, and/or the like. In at least one example embodiment, the touch input comprises an intent designation input. 
     In some circumstances, it may be desirable to allow a user to perform non-trivial input in association with a grip surface of the apparatus. For example, it may be desirable for the user to provide an input that comprises one or more movement inputs, one or more contact inputs, one or more release inputs, and/or the like. In at least one example embodiment, the touch input comprises an interaction input. In at least one example embodiment, the interaction input relates to input provided by the user for the purpose of performing input. For example, interaction input may relate to input that is intentional by the user. In at least one example embodiment, the interaction input is distinct from the intent designation input. For example, the user may perform the intent designation input before performing the interaction input. In this manner, the user may communicate to the device that the interaction input is non-accidental by way of performing the intent designation input. There may be more than one interaction input. For example, the interaction input may be a continuous stroke input. In such an example, the continuous stroke input may comprise a movement input indicative of movement in a direction and another movement input indicative of movement in a different direction. 
     In at least one example embodiment, the interaction input is subsequent to the intent designation input. For example, the apparatus may determine the interaction input based, at least in part, on input subsequent to an intent designation input. In at least one example embodiment, the apparatus determines the interaction input based, at least in part, the touch input being indicative of continuous contact between the intent designation input and the interaction input. For example the apparatus may determine the interaction input to be a continuous stroke input having a contact input that is part of the intent designation input, that is received within a time threshold from the intent designation input, and/or the like. 
     In at least one example embodiment, the interaction input relates to a movement input subsequent to the intent designation input. For example, the interaction input may relate to a sliding input. For example, the sliding input may be utilized to adjust a camera focus, a volume setting, a zoom level, a flash brightness, a value of a setting, and/or the like. 
     In at least one example embodiment, the interaction input relates to an increase in a force of the touch input subsequent to the intent designation input. The apparatus may determine an increase in force by determining an increase in the size of a contact region of the touch input, by way of one or more force sensors, and/or the like. In at least one example embodiment, the interaction input relates to the force surpassing a threshold force. For example, the threshold force may be similar to a force associated with actuation of a mechanical input actuation device. 
     In at least one example embodiment, the intent designation input relates to a plurality of contact regions within the region, and the interaction input relates to a movement of the contact regions. For example, the movement of the contact regions may relate to a change in distance between the contact regions, similar as described regarding  FIG. 3E . In another example, the movement of the contact regions may relate to a change in position of the contact regions within a region of the grip region. Such change in position may be similar as movement  324  of  FIG. 3B . 
     In some circumstances, the touch input may comprise one or more inputs prior to the intent designation input. In at least one example embodiment, the apparatus disregards inputs prior to an intent designation input. Without limiting the scope of the claims in any way, at least one technical effect associated with disregarding inputs prior to a an intent designation input may be to avoid performing an operation in response to an inadvertent input, avoiding input prior to an intent designation input from being considered as an interaction input, and/or the like. 
     In at least one example embodiment, the apparatus may determine that a received touch input comprises at least one intent designation input. For example, the apparatus may disregard touch input associated with a region of a grip surface absent determination that the touch input comprises at least one intent designation input. In at least one example embodiment, determination of whether a touch input comprises an intent designation input is predicated by the touch input being associated with a region of the grip surface. For example, if the touch input is associated with a region of a non-grip surface, for example on the front surface of an apparatus, on a primary display of an apparatus, and/or the like, the apparatus may perform an operation based, at least in part, on the touch input without regard for whether the touch input comprises an intent designation input. For example, the apparatus may receive an indication of a touch input that is unassociated with a region of a grip surface. In such an example, the apparatus may perform an operation based, at least in part, on the touch input absent consideration of an intent designation input. 
     In at least one example embodiment, the apparatus determines that the touch input is associated with the grip surface. For example, the apparatus may determine that the touch input is associated with a touch sensor associated with a grip surface, that the touch input is associated with a region of a touch sensor that is associated with a grip surface, and/or the like. 
     In at least one example embodiment, the apparatus determines that the touch input comprises at least one interaction input. The apparatus may determine the interaction input to be touch inputs that occur subsequent to the intent designation input, touch inputs that are part of a continuous stroke input in which the contact input of the continuous stroke input is comprised by the intent designation input, and/or the like. In at least one example embodiment, determination that the touch input comprises at least one interaction input is predicated by determination that the touch input comprises the intent designation input. 
     In some circumstances, it may be desirable to provide a user with feedback associated with an intent designation input. For example, a user may desire sensory feedback similar to the sensory feedback associated with actuation of a mechanical input actuation device, clicking of a button, and/or the like. In at least one example embodiment, the apparatus may cause rendering of at least one haptic signal in association with determination of the intent designation input. In at least one example embodiment, rendering of a haptic signal relates to invoking a vibration signal, a tactile signal, and/or the like. It should be understood that there are many methods and devices for providing haptic signals to a user, and that there will be many more methods and devices that will be provided in the future for providing haptic signals to a user, and that the claims are not limited by such methods and devices. In at least one example embodiment the apparatus may cause rendering of a haptic signal based, at least in part, on determination that the touch input comprises an intent designation input, comprises a part of an input designation input, and/or the like. Without limiting the scope of the claims in any way, at least one technical effect associated with rendering the haptic signal in association with determination of the intent designation input may be to allow the user to understand that the apparatus has perceived, at least part of, an intent designation input. In such circumstances, the user may take action to avoid inadvertent input, may gain confidence in performance of an intentional input, and/or the like. 
     In at least one example embodiment, the apparatus performs an operation associated with a grip surface touch input based, at least in part, on the intent designation input. For example, the apparatus may perform the operation in response to the intent designation input, in response to an interaction input, and/or the like. In at least one example embodiment, the apparatus precludes performance of the operation associated with a grip surface touch input based, at least in part, on the grip surface touch input failing to comprise the intent designation input. For example, the apparatus my preclude preforming an operation in response to the grip surface touch input based at least in part on the grip surface touch input failing to comprise an intent designation input. 
     In at least one example embodiment, the operation is based, at least in part on the intent designation input. For example, the intent designation input may relate to a region of the grip surface of the apparatus. In such an example, the operation may be based, at least in part on the region of the grip surface. The region may be any region partitioned by the apparatus. For example, different regions may relate to different grip surfaces, different parts of the same grip surface, different touch sensors, different parts of the same touch sensor, and/or the like. For example, the apparatus may perform an operation based, at least in part, on the intent designation input being associated with a region and perform a different operation based, at least in part, on the intent designation input being associated with a different region. 
     As previously described, the touch input may comprise inputs prior to the intent designation input. In such circumstances, the operation may be independent of the input prior to the intent designation input. For example, the apparatus may determine the operation absent consideration of the input prior to the intent designation input. 
     In at least one example embodiment, the operation is based, at least in part on the interaction input. For example, performance of the operation may be predicated on performance of a predetermined interaction input associated with the operation. In such an example, the predetermined interaction input may relate to an interaction input that is designated to cause invocation of the operation. For example, a tap input may be associated with causation of invocation of an operation, a slide input may be associated with causation of setting a value of a parameter, and/or the like. For example, a tap interaction input may relate to performing an adjustment of a parameter by an increment, skipping to a next song, skipping to a previous song, toggling enablement of a camera flash, taking a photo, toggling enablement of a display, toggling enablement of a lock, and/or the like. In another example, a slide interaction input may relate to a continuous adjustment, such as volume control, zoom control, camera white balance control, camera brightness control, scrolling up or down, paging up or down, panning backwards or forwards, and/or the like. 
     In some circumstances, an apparatus may comprise platform software that causes the apparatus to perform in a predetermined manner that complies with an associated platform. For example, a platform may be an operating system, an operating environment, a performance specification, and/or the like. For example, the platform may be a Microsoft Windows® platform, a Google Android® platform, and/or the like. In such circumstances, it may be desirable for the apparatus to comply with one or more platform compliance criteria. A platform compliance criteria may relate to a designated set of directives that the apparatus should fulfill in order to be deemed compliant with the platform. For example, identification of an apparatus as an apparatus of the specified platform may be predicated on the apparatus satisfying the platform compliance criteria. 
     In at least one example embodiment, a platform compliance criteria may specify one or more input actuation devices to be comprised by the apparatus. For example, the platform compliance criteria may specify presence of a power button, a camera button, a home button, a volume up button, a volume down button, a back button, a search button, and/or the like. In such circumstances, the platform compliance criteria may specify platform operations to invoke in response to receiving input associated with such specified input actuation devices. For example, the platform compliance criteria may specify that, under some circumstances, actuation of the home button causes the apparatus to present a home screen to the user, actuation of the camera button causes a camera program to run, actuation of the camera button causes the camera program to capture an image, actuation of the volume up button causes the apparatus volume to increase, and/or the like. In this manner, the operation may be associated with an input button of a platform compliance criteria. In at least one example embodiment, the apparatus may perform an operation that relates to invocation of a platform input directive that identifies the button input of the platform compliance specification. For example, platform input directive may relate to a function call, a message, and/or the like, to be invoked upon receipt of an input invoking the button press. 
     As previously described, it may be desirable to utilize one or more touch sensors instead of utilizing one or more mechanical input actuation devices. In such circumstances, it may be desirable to map a touch input to a button input of the platform software. For example, based, at least in part, on determining that a touch input associated with a region of a grip surface comprises an intent designation input, the apparatus may invoke a platform input directive associated with a button input specified by the platform compliance criteria. In at least one example embodiment, mapping may relate to determining a platform invocation directive to associate with an input, such as an intent designation input associated with a region of a grip surface of the apparatus.

The example of  FIG. 4A  illustrates region  404  of a grip surface of apparatus  402 . It can be seen that the grip surface associated with region  404  is an edge of the apparatus. In at least one example embodiment, the apparatus causes performance of an operation based, at least in part, on determining that a touch input associated with region  404  comprises an intent designation input. The apparatus may comprise one or more touch sensors that correlate to region  404 . 
       FIG. 4B  is a diagram illustrating regions of a grip surface according to at least one example embodiment.

In at least one example embodiment, the apparatus causes performance of a different operation based, at least in part, on determining that a touch input associated with region  428  comprises an intent designation input. For example, region  424  may relate to a power operation, region  426  may relate to a volume up operation, region  428  may relate to a volume down operation, region  430  may relate to a camera operation, and/or the like. The apparatus may comprise one or more touch sensors that correlate to regions  424 ,  426 ,  428 , and  430 . 
       FIG. 4C  is a diagram illustrating regions of a grip surface according to at least one example embodiment. The example of  FIG. 4C  illustrates regions  444  and  446  of at least one grip surface of apparatus  442 . It can be seen that the grip surface associated with regions  444  and  446  is a back surface of the apparatus. In at least one example embodiment, the apparatus causes performance of an operation based, at least in part, on determining that a touch input associated with region  446  comprises an intent designation input. In at least one example embodiment, the apparatus causes performance of a different operation based, at least in part, on determining that a touch input associated with region  444  comprises an intent designation input. For example, region  444  may relate to a volume up operation, region  446  may relate to a volume down operation, and/or the like. The apparatus may comprise one or more touch sensors that correlate to regions  444  and  446 . 
       FIG. 4D  is a diagram illustrating a region of a grip surface according to at least one example embodiment. The example of  FIG. 4D  illustrates region  464  of a grip surface of apparatus  462 . It can be seen that the grip surface associated with region  464  is a back surface of the apparatus. In at least one example embodiment, the apparatus causes performance of an operation based, at least in part, on determining that a touch input associated with region  464  comprises an intent designation input. For example, region  464  may relate to a volume operation. For example, an interaction input comprising a movement input may cause change in a value of the volume. The apparatus may comprise one or more touch sensors that correlate to region  464 . 
       FIGS. 5A-5C  are diagrams illustrating indications of regions according to at least one example embodiment. The examples of  FIGS. 5A-5C  are merely examples, and do not limit the scope of the claims. For example, position of an indication may vary, shape of an indication may vary, size of an indication may vary, and/or the like. 
     In at least one example embodiment, the apparatus may comprise at least one indication of a region of a grip surface of the apparatus associated with an operation. The indication may be a textural indication, a visual indication, and/or the like. 
     A textural indication may relate to one or more surface concavities, one or more surface convexities, and/or the like. For example, the textural indication may identify one or more boundaries of the associated region. In another example, the textural indication may be indicative of an operation associated with the region. In another example, the textural indication may be indicative of an interaction input that may be performed in association with the region. 
     A visual indication may relate to one or more visual representation. The visual indication may be a visual representation upon a surface of the apparatus, such as a label. The visual indication may be a visual indication provided by a display. For example, the touch sensor associated with a region of a grip surface of the apparatus may relate to a touch display. The visual indication may identify one or more aspect of the region. For example, the visual indication may identify one or more boundaries of the associated region. In another example, the visual indication may be indicative of an operation associated with the region. In another example, the visual indication may be indicative of an interaction input that may be performed in association with the region. Even though the examples of  FIGS. 5A-5C  are discussed in relation to textural indicators, some example embodiments may utilize visual indictors, and/or other types of indicators. 
       FIG. 5A  is a diagram illustrating indications of a grip surface according to at least one example embodiment. In the example of  FIG. 5A , grip surface  500  comprises textural representation  501 , which is a raised ridge forming a track for sliding in association with another region, and textural representation  502 , which is another raised ridge forming a track for sliding in association with another region. It can be seen that in resembling a ridge for sliding, textural representations  501  and  502  are indicative of a movement input associated with a slider interface element. Such a textural representation may be indicative of adjustment of a value of a setting. 
       FIG. 5B  is a diagram illustrating indications of grip surface  520  according to at least one example embodiment. In the example of  FIG. 5B , textural representations  521 ,  522 ,  523 , and  524  are raised ridges that indicate particular regions of a grip surface. In the example of  FIG. 5B , one or more of textural representations  521 ,  522 ,  523 , and  524  may indicate a region associated with a shutter release operation, may indicate a region input for zoom of a camera program, may indicate an operation for setting a value associated with operation of a flash, and/or the like. Textural representations  521 ,  522 ,  523 , and  524  may be indicative of selectable buttons on the edge of an apparatus. 
     In at least one embodiment, even though an indicator may signify a region, the region associated with the indicated input may be larger than the identifier. For example, an indicator may represent a button. However, in such an example, the region may be larger than the indication of a button. In such circumstances, it may be desirable to provide an indication of a boundary of the region. 
       FIG. 5C  is a diagram illustrating an indication of a grip surface according to at least one example embodiment. In the example of  FIG. 5C , grip surface  540  comprises textural indication  541 , which relates to a raised circle indicative of a selectable button. In at least one example embodiment, textural indication  541  identifies a region of grip surface  540  that may receive input, such as a tap input, a press input, and/or the like. 
       FIGS. 6A-6D  are diagrams illustrating information displayed in association with adjustment of a value of a setting according to at least one example embodiment. The examples of  FIGS. 6A-6D  are merely examples, and do not limit the scope of the claims. For example, representation of information may vary, arrangement of elements may vary, orientation of the display may vary, and/or the like. 
     As touch displays have become more ubiquitous on various types of electronic apparatuses, the proportion of the surface of electronic apparatuses that are allocated to a display has increased. In this manner, users now enjoy much larger displays for similarly sized apparatuses than in previous times. With such expansion of touch display utilization, users have become accustomed to performing inputs by way of a touch display. Performance of input on a touch display often includes the user placing a hand, finger, stylus, and/or the like, on the display. In such circumstances, such touch input may, at least partially, occlude a portion of the display. For example, the display may be occluded at a region where the contact takes place, at a region beneath an object performing the contact, etc. For example, a user may perform a touch input with his finger. In such an example, the region of the display in which the user&#39;s finger is contacting the display may be occluded by such contact. However, the rest of the user&#39;s finger, the user&#39;s hand, the user&#39;s arm, and/or the lie, may also occlude, at least part of, the display. In some circumstances, it may be desirable to reduce occlusion of the display associated with a touch display touch input. 
     In some circumstances, the apparatus may provide information indicating a region of a touch display in which the user may perform input, such as a button, an icon, a slider, and/or the like. In some circumstances, such information may, at least partially occlude other information to be presented on the display. For example, there may be an image upon with the information is overlain. In such an example, the information may, at least partially, occlude the image. 
     In at least one example embodiment, it may be desirable to avoid occlusion of content to be presented on a display by performance of a display touch input, by provision of interface elements associated with a display touch input, and/or the like. For example, even though it may be desirable to provide for some interface elements on a touch display, it may be desirable to provide for interaction by way of another input that does not occlude any part of the display. 
     For example, many applications benefit from the user being capable of viewing as much of the display as possible, such as image capturing applications, gaming applications, and/or the like. In such circumstances, the user may benefit from being able to perceive content that would otherwise be occluded by interface elements, by an object performing an input, and/or the like. For example, it may be desirable to provide for input of an image capture application, such as an image viewfinder interface, that utilizes touch input associated with a grip surface of the apparatus. In such circumstances, the apparatus may avoid obscurance, by interface elements of object performing input, of an image that the user may desire to capture. For example, it may be desirable for a user to be able to adjust one or more image settings without necessarily obscuring any portion of the display, with reduced obscurance of the display, and/or the like. For example, it may be desirable to perform a setting adjustment absent any interface elements on the display, absent any interface elements beyond an indication of the setting, absent any interface elements beyond an indication of the setting and an indication of the value of the setting, absent any interface elements beyond a list of settings that may be modified, an indication of the setting, and an indication of the value of the setting. 
     In some circumstances, it may be desirable to allow the user to utilize regions of a grip surface for adjusting one or more settings, such as one or more camera settings of a viewfinder application. In such an example, the user may perform an input associated with a first region of a grip surface to identify a setting to be adjusted, and may perform a different input to instruct the apparatus regarding how to adjust the value of the setting. Without limiting the scope of the claims in any way, at least one technical effect associated with a separate input for selection of a setting and a separate input for adjustment of the input may be to allow for a consistent region associated with adjustment of a setting such that the user may readily understand how to adjust a setting that the user has not previously adjusted, based on the users experience in adjusting other settings. 
       FIG. 6A  is a diagram illustrating information displayed in association with adjustment of a value of a setting according to at least one example embodiment. In the example of  FIG. 6A , apparatus  600  is displaying content on display  601 . In at least one example embodiment, the content relates to an image associated with a viewfinder. For example, apparatus  600  may be running an image capture program such that content displayed on display  601  is indicative of an image that may be captured. It can be seen that interface item  602  may relate to an image capture operation. For example, the user may perform a touch input at a position of display  601  that corresponds with interface element  602  to invoke an image capture operation. In some circumstances, it may be desirable for the user to be able to adjust one or more settings while avoiding undue obscurance of the content displayed in relation to the viewfinder. 
     In at least one example embodiment, an apparatus provides for input by way of one or more grip surfaces for adjustment of a value of one or more settings. A setting may relate to any parameter of the apparatus that may be adjustable. For example a setting may relate to a volume level, a brightness level, and/or the like. In some circumstances a setting may relate to a program setting. In at least one example embodiment, a program setting relates to a setting that governs one or more aspects for the program. For example, a program setting of an image capture program may relate to a shutter speed setting, a color balance setting, a flash setting, a zoom setting, a resolution setting, and/or the like. In at least one example embodiment, a setting has a value. For example, the value may indicate how the setting should affect the apparatus. For example, the value may be an integer value, a floating point value, and enumerated value, a Boolean value, and or the like. For example a value of a flash setting may be a Boolean value that indicates the flash to be on or off, may be an integer value that provides a scale for brightness of the flash, and/or the like. In at least one example embodiment, adjustment of the setting relates to adjustment of the value of the setting. For example, adjustment of the value of the setting may comprise changing the value of the setting to a different value. In another example, the value of a lens setting may be a particular lens type from an enumerated set of lens types. For example, the setting may relate to a lens selection and the value of the setting may be a particular lens type from an enumerated set of lens types. In still another example, the value of a sharing setting may relate to a value that indicates a medium for sharing information, such as an email account, a social media account, a particular communication channel, etc., a contact record that designates a recipient, such as a phonebook entry, an email address, a phone number, a screen name, etc., and/or the like. 
     The apparatus may provide for input by way of one or more grip surfaces for adjustment of a value of one or more settings, similar as described regarding the examples of  FIGS. 4A-4D ,  FIGS. 5A-5C , and/or the like. For example, the apparatus may associated one or more regions of one or more grip surfaces with a particular setting, may associate one or more regions of one or more grip surfaces with an adjustment of a value, and/or the like. For example, the apparatus may comprise textural indicators similarly as described regarding  FIG. 5B  such that the program associates a region of the grip surface that corresponds with the textural indicator with a setting. For example, textural indicator  521  may indicate a region of the grip surface that is associated with selection of a particular setting. Similarly, textural indicators  501  and/or  502  may indicate a particular type of setting adjustment. In this manner, the textural indicator may identify one or more regions of the grip surface with one or more settings that may be selected, one or more ways to adjust a value of a selected setting, and/or the like. Even though textural indicators may be helpful for the user to perceive one or more regions of the grip surface that may be associated with an input, other manners may be utilized to allow the user to understand such regions. For example, there may be a visual indicator, on the grip surface, an inference of the region on a display, or even a complete absence of any indicator. For example, the user may associate a particular region of a grip surface with a particular setting or adjustment absent any indicator of the region. 
     In at least one example embodiment, an apparatus relies upon two inputs for performance of adjustment of a setting. The apparatus may receive an input indicative of selection of a particular setting, and receive an indication of another input indicative of adjustment of the selected setting. In at least one example embodiment, the input indicative of the adjustment of the value is concurrent with the input indicative of the selection of the setting. For example, the apparatus may preclude adjustment of the setting absent concurrency between the input indicative of selection of the setting and the input indicative of the adjustment of the setting. In at least one example embodiment, the input indicative of the selection of the setting is a separate input from the input indicative of the adjustment of the setting. For example, the inputs may be associated with different regions of the grip surface, associated with different grip surfaces, and/or the like. For example, the input associated with selection of the setting may be associated with a top edge of the apparatus and the input associated with adjustment of the setting may be associated with a bottom edge of the apparatus. In another example, the input associated with selection of the setting may be associated with a region of a top edge of the apparatus and the input associated with adjustment of the setting may be associated with a different region of the top edge of the apparatus 
     In at least one example embodiment, an apparatus that receives a first touch input associated with a region of a grip surface determines whether the first touch input is a setting designation input. In at least one example embodiment, a setting designation input relates to a touch input that identifies one or more settings to be adjusted. In at least one example embodiment, the setting designation unambiguously identifies a setting. For example, there may be a single setting, or a distinct group of settings that a setting designation input designates. For example the region may be a region that is predetermined to be a region associated with selection of the setting. In at least one example embodiment, that the first touch input is a setting designation input that designates the setting for adjustment is based, at least in part, on position of the first touch input. For example, the determination that the first touch input is a setting designation input that designates the setting for adjustment may be based, at least in part, on correlation of a position of the first touch input and a position associated with at least one textural indicator, a position included within a predetermined region associated with the setting, and/or the like. In at least one example embodiment, a setting designation input relates to an intent designation input. 
     In at least one example embodiment, the first touch input comprises a contact input and a release input, similarly as described regarding  FIGS. 3A-3E . In at least one example embodiment, the apparatus allows adjustment of a value of the setting during a time period between the contact input of the first touch input and the release input of the first touch input. In this manner, the performance of adjustment of the value of the setting may be predicated by continued contact of the first touch input during receipt of the second touch input. 
     In at least one example embodiment, the apparatus receives an indication of a second touch input. The second touch input may be associated with a different region of a grip surface of the apparatus than the first input, and be separate from the first touch input. In at least one example embodiment, the apparatus performs adjustment of a value of the setting based, at least in part, on the second touch input. For example, while the first input is being performed to be a setting designation input that identifies the setting for adjustment, the second input causes the apparatus to perform adjustment of the value of the setting. In some circumstances, the second touch input corresponds with at least one predetermined grip region associated with adjustment of the setting. In at least one example embodiment, the apparatus predicates adjustment of the setting upon determination that the second touch input corresponds with at least one predetermined grip region associated with adjustment of the setting. For example, the predetermined region may be a region that is predetermined to be associated with adjustment absent regard for the particular setting, predetermined to be associated with a group of settings that includes the setting, predetermined to be associated particularly with adjustment of the setting, and/or the like. 
     In some circumstances, the first touch input and the second touch input may be absent a touch input at a position on a touch display. For example, the touch sensor of a touch display may be unassociated with the receipt of the first touch input and/or receipt of the second touch input. In at least one example embodiment, the first touch input and the second touch input are absent motion of the apparatus. For example, it may be desirable for the user to be able to maintain position of the apparatus, direction of the apparatus, orientation of the apparatus, and/or the like, when performing the first input and/or the second touch input. For example, the setting may relate to an image capture setting. In such an example the user may desire to avoid motion of the apparatus. In such an example, the first input and the second input may be absent inclusion of information indicative of motion. In this manner, the first input and the second input may be non-motion inputs. 
     In at least one example embodiment, the apparatus causes display of a setting indicator that identifies the setting. In at least one example embodiment, causation of display comprises display information, sending information to a separate apparatus to be displayed, and/or the like. The setting indicator may be a graphical representation that indicates the setting, may be a textual indication that indicates the setting, and/or the like. For example, the setting may relate to a shutter speed setting, and the graphical representation may relate to an icon that resembles a camera shutter. In at least one example embodiment, the apparatus causes display of the setting indicator based on the determination that the first input is a setting designation input. In this manner, the user may identify the setting associated with the input that the user is performing. For example the user may have inadvertently selected the setting may have inadvertently performed the input, and/or the like, such that display of the setting indicator may cue the user to the inadvertent circumstances. In at least one example embodiment, the apparatus causes termination of display of the setting indicator. Causation of termination of display of information may relate to cessation of display of the information, causation of a separate apparatus to cease display of the information, and/or the like. 
     In at least one example embodiment, the apparatus causes display of an indication of the value of the setting. For example, upon determination that the first input is a setting designation input, the apparatus may cause display of information indicative of the value of the setting. Similarly, upon performing adjustment of the value of the setting, the apparatus may cause display of an indication of the value of the setting. In this manner, the user may be aided in perceiving the setting that is designated for adjustment, the value of the setting prior to adjustment, the value of the setting after adjustment, and/or the like. The indication of the value of the setting may relate to a graphical representation of the value. The graphical representation of the value may relate to a level of shading that indicates the value, a graphical representation that indicates the value as a position along a line, and/or the like. The indication of the value of the setting may relate to a textual representation of the value. For example, the indication of the value of the setting may be text that shows a number that corresponds with the value of the setting. In at least one example embodiment, causation of display of the indication of the value of the setting is caused by receipt of the first touch input, caused by determination that the first touch input is a setting designation input, and/or the like. 
     In at least one example embodiment, causation of display of the indication of the value of the setting is caused by receipt of the second touch input, caused by adjustment of the value of the setting, and/or the like. In at least one example embodiment, the apparatus causes termination of display of the indication of the value of the setting. In at least one example embodiment, the termination of display of the indication of the value of the setting is caused by the receipt of the release input of the first touch input. In at least one example embodiment, the termination of display of the indication of the value of the setting is caused by receipt of a release input of the second touch input. In this manner, the display of the value of the setting may be reduced to coincide with a time period in which the user is performing input that may cause adjustment of the value of the setting. In this manner, the content that may be displayed may be less occluded, may be occluded for less time, and/or the like. 
       FIG. 6B  is a diagram illustrating information displayed in association with adjustment of a value of a setting according to at least one example embodiment. In the example of  FIG. 6B , apparatus  610  is displaying content on display  611 . In at least one example embodiment, the content relates to an image associated with a viewfinder. For example, apparatus  610  may be running an image capture program such that content displayed on display  611  is indicative of an image that may be captured. It can be seen that interface item  612  may relate to an image capture operation. For example, the user may perform a touch input at a position of display  611  that corresponds with interface element  612  to invoke an image capture operation. In the example of  FIG. 6B , apparatus  610  has caused display of a graphical indication of the value of a setting. The graphical indicator of the example of  FIG. 6B  comprises line  613  and value indication point  614 , such that position of value indication point  614  along line  613  indicates the value of the setting. For example, proximity of value indication point towards the bottom of the display may be indicative of a lower value than proximity to the top of the display. 
     In at least one example embodiment, the apparatus display of a plurality of indicators of adjustable settings. In at least one example embodiment, an adjustable setting relates to a setting that may be selected for adjustment, for example by a setting designation input. For example, there may be a plurality of settings that a user may select to adjust. In such an example, there may be indicators of adjustable settings that identify, at least some of, the settings that the user may select for adjustment. In at least one example embodiment, the setting indicator previously described relates to a setting indicator that identifies one of the indicators of the plurality of indicators of adjustable settings as the setting. For example, the setting indicator may be a difference between the indicator of the adjustable setting that corresponds to the setting, and the other indicators of the adjustable settings. For example, the setting indicator may relate to a highlighted indicator of an adjustable setting, an adjustable setting that comprises a value indicator, and/or the like. 
       FIG. 6C  is a diagram illustrating information displayed in association with adjustment of a value of a setting according to at least one example embodiment. In the example of  FIG. 6C , apparatus  620  is displaying content on display  621 . In at least one example embodiment, the content relates to an image associated with a viewfinder. For example, apparatus  620  may be running an image capture program such that content displayed on display  621  is indicative of an image that may be captured. It can be seen that interface item  622  may relate to an image capture operation. It can be seen that the example of  FIG. 6C  comprises indicators  630 ,  631 ,  632 ,  633 , and  634  of adjustable settings. 
     In at least one example embodiment, position of the indicators of adjustable settings may be indicative of a region of a grip surface that corresponds with a setting designation input. It can be seen that indicators  630 ,  631 ,  632 ,  633 , and  634  of adjustable settings are proximate the top edge of apparatus  620 . In this manner, the proximity of the indicators of adjustable settings to the top edge of the apparatus may be indicative of regions of the top edge of the apparatus comprising one or more grip regions associated with one or more setting designation inputs for the settings of the setting adjustment indicators. 
     In at least one example embodiment, determination that the first touch input is a setting designation input that designates the setting for adjustment is based, at least in part, on alignment of a position of the first touch input and a setting indicator that identifies the setting along a common axis. The common axis may relate to a vertical axis, a horizontal axis, and/or the like. For example, a region of the top edge of apparatus  620  that is vertically aligned with setting indicator  630  may relate to a region associated with a setting designation input that designates the setting of setting indicator  630 . 
     In some circumstance, the apparatus may cause display of the indicators of adjustable settings absent receipt of the first input. In such an example, the indicators of adjustable settings may indicate one or more regions of a grip surface associated with a setting designation input for one or more of the adjustable settings, and the user may desire to have a visual indication of such region on the display. 
     In at least one example embodiment, causation of display of the plurality of indicators of adjustable settings is caused by receipt of the second touch input, caused by adjustment of the value of the setting, and/or the like. In at least one example embodiment, the apparatus causes termination of display of the plurality of indicators of adjustable settings. In at least one example embodiment, the termination of display of the plurality of indicators of adjustable settings is caused by the receipt of the release input of the first touch input. In at least one example embodiment, the termination of display of the plurality of indicators of adjustable settings is caused by receipt of a release input of the second touch input. In this manner, the display of the plurality of indicators of adjustable settings may be reduced to coincide with a time period in which the user is performing input that may cause adjustment of the value of the setting. In this manner, the content that may be displayed may be less occluded, may be occluded for less time, and/or the like. 
     Even though the information that may be displayed are described separately from each other, various embodiments may include various aspects of the information to be displayed. For example, an apparatus may combine any part of the information displayed in the examples of  FIGS. 6A-6C , and/or anything similar. In another example, an apparatus may combine any plurality of parts of the information displayed in the examples of  FIGS. 6A-6C . 
       FIG. 6D  is a diagram illustrating information displayed in association with adjustment of a value of a setting according to at least one example embodiment. In the example of  FIG. 6D , an embodiment is shown that combines displayed information of  FIG. 6C  with displayed information of  FIG. 6B . 
     In the example of  FIG. 6D , apparatus  640  is displaying content on display  641 . It can be seen that interface item  642  may relate to an image capture operation. It can be seen that the example of  FIG. 6D  comprises indicators  650 ,  651 ,  652 ,  653 , and  654  of adjustable settings. In the example of  FIG. 6D , apparatus  640  has caused display of a graphical indication of the value of a setting. The graphical indicator of the example of FIG.  6 D comprises line  643  and value indication point  644 , such that position of value indication point  644  along line  643  indicates the value of the setting. In at least one example embodiment, the setting of the graphical indication of the value of the setting relates to one of the settings of indicators  650 ,  651 ,  652 ,  653 , and  654  of adjustable settings. 
     In at least one example embodiment, the setting relates to performance of an operation. For example, the setting may relate to an image capture setting, such as a lens selection setting, a flash setting, a shutter speed setting, a communication setting, an account selection setting, and/or the like. In at least one example embodiment, the apparatus performs the operation in conformance with the value of the setting. Performance of the operation in conformance with the value of the setting may relate to the performance of the operation being based, at least in part, on the value of the setting. For example, the apparatus may perform the operation based on a value of the setting, and perform the operation differently based, at least in part, on a different value of the same setting. For example, an image capture operation may be performed in conformance with a flash utilization setting. In such an example, the image capture operation may condition utilization of the flash based, at least in part, on the value of the flash utilization setting. For example, if the flash utilization setting indicates flash enablement, the image capture operation may invoke utilization of the flash based, at least in part, on the flash enablement value of the flash utilization setting. 
     In at least one example embodiment, the apparatus performs the operation in conformance with the value of the setting based, at least in part, on receipt of a third touch input. For example, the apparatus may perform an image capture operation in conformance with the value of the setting based, at least in part, on receipt of a touch input indicative of selection of interface item  642  of  FIG. 6D . In such an example, the apparatus may cause adjustment of the value of the setting prior to the third touch input. 
     In at least one example embodiment, the apparatus performs the operation in conformance with the value of the setting based, at least in part, on receipt of the release input of the first touch input. For example, the setting may relate to a sharing setting, and the value of the setting may relate to at least one of a medium for sharing, such as an email account, a social media account, a particular communication channel, etc., may relate to at least one contact to share information with, such as a phonebook entry, a phone number, a distribution list, etc. In such an example, the release input of the first touch input may cause the apparatus to perform the sharing of information in conformance with the sharing setting that was adjusted by way of the first touch input and the second touch input. In such an example, the user may perform a setting designation input that designates the sharing setting, perform an adjustment input associated with selection of a value for the sharing setting (such as medium and/or recipient of the information), and invoke the sharing operation by releasing the setting designation input. In this manner, the release input of the sharing setting designation input may cause performance of the sharing operation in conformance with the value of the sharing setting. 
       FIG. 7  is a flow diagram illustrating activities associated with adjustment of a value of a setting according to at least one example embodiment. In at least one example embodiment, there is a set of operations that corresponds with the activities of  FIG. 7 . An apparatus, for example electronic apparatus  10  of  FIG. 1 , or a portion thereof, may utilize the set of operations. The apparatus may comprise means, including, for example processor  11  of  FIG. 1 , for performance of such operations. In an example embodiment, an apparatus, for example electronic apparatus  10  of  FIG. 1 , is transformed by having memory, for example memory  12  of  FIG. 1 , comprising computer code configured to, working with a processor, for example processor  11  of  FIG. 1 , cause the apparatus to perform set of operations of  FIG. 7 . 
     At block  702 , the apparatus receives an indication of a first touch input that is associated with a region of a grip surface of an apparatus, the first touch input comprising a contact input. The receipt, the first touch input, the region, the grip surface, and the contact input may be similar as described regarding  FIGS. 2A-2D ,  FIGS. 3A-3E ,  FIGS. 4A-4D ,  FIGS. 5A-5C , and/or the like. 
     At block  704 , the apparatus determines whether the first touch input is a setting designation input that designates a setting for adjustment. If the apparatus determines that the first touch input is a setting designation input that designates a setting for adjustment, flow proceeds to block  706 . If the apparatus determines that the first touch input differs from a setting designation input that designates a setting for adjustment, flow returns to block  702 . The determination and the setting designation input may be similar as described regarding  FIGS. 3A-3E ,  FIGS. 6A-6D , and/or the like. In at least one example embodiment, determination that the first touch input is a setting designation input is predicated by the first touch input being associated with the region of the grip surface. In at least one example embodiment, the apparatus further performs a determination that the first touch input is associated with the region of the grip surface. In such an example, determination that the first touch input is a setting designation input may be predicated by the first touch input being associated with the region of the grip surface. In at least one example embodiment, the determination that the first touch input is a setting designation input that designates a setting for adjustment is based, at least in part, on a determination that the contact input of the first touch input exceeds a threshold force. For example, the apparatus may receive force sensor information associated with the first touch input. In such an example, the determination that the contact input of the first touch input exceeds a threshold force may be based, at least in part, on force sensor information.

       FIG. 9  is a flow diagram illustrating activities associated with adjustment of a value of a setting according to at least one example embodiment. In at least one example embodiment, there is a set of operations that corresponds with the activities of  FIG. 9 . An apparatus, for example electronic apparatus  10  of  FIG. 1 , or a portion thereof, may utilize the set of operations. The apparatus may comprise means, including, for example processor  11  of  FIG. 1 , for performance of such operations. In an example embodiment, an apparatus, for example electronic apparatus  10  of  FIG. 1 , is transformed by having memory, for example memory  12  of  FIG. 1 , comprising computer code configured to, working with a processor, for example processor  11  of  FIG. 1 , cause the apparatus to perform set of operations of  FIG. 9 . 
     In some circumstances, it may be desirable for the type of input that the user performs for adjustment of the value of the setting to impact the manner in which the value of the setting is adjusted. For example, it may be desirable for the user to perform a tap input to adjust the value of the setting. In such an example, the region of the grip surface in which the user performs the tap input may identify an increment adjustment of the value of the setting, a decrement adjustment of the value of the setting, magnitude of the adjustment of the value of the setting, and/or the like. For example, it may be desirable for the user to perform a touch input at a region of an edge of the apparatus to invoke an increment adjustment of the value the setting, and for the user to perform a touch input at a region of an opposite edge of the apparatus to invoke a decrement adjustment of the value of the setting. In this manner, it may be intuitive to the user that opposite edges of the apparatus may be utilized for increment and decrement adjustment designation. 
     In at least one example embodiment, during a setting designation input, the apparatus may receive an indication of a tap input. The apparatus may perform an adjustment of the value of the setting designated by the setting designation input by way of a decrement of the value of the setting by a predetermined value, by way of an increment of the value of the setting by a predetermined value, and/or the like. The predetermined value of the increment and/or the decrement may be unitary, may be based on position of the tap input, may be based on a stored adjustment value, and/or the like. In at least one example embodiment, determination to perform an increment is based, at least in part, on the region of the grip surface of the tap input being associated with an increment adjustment. For example, a region of the top edge of the apparatus may relate to an increment adjustment. In another example, a region of the right edge of the apparatus may relate to an increment adjustment. Similarly, in at least one example embodiment, determination to perform the decrement is based, at least in part, on the region of the grip surface of the tap input being associated with a decrement adjustment. For example, a region of the bottom edge of the apparatus may relate to a decrement adjustment. In another example, a region of the left edge of the apparatus may relate to a decrement adjustment. In this manner, the user may readily understand which grip surface upon which to perform the input based on alignment of the increment and/or decrement with geometric conventions of numeric increase being upward and/or rightward, and numeric decrease being downward and/or leftward. In this manner, polarity of the adjustment may be based, at least in part, on position of the touch input associated with adjustment of the value of the setting. 
     At block  902 , the apparatus receives an indication of a first touch input that is associated with a region of a grip surface of an apparatus, the first touch input comprising a contact input, similarly as described regarding block  702  of  FIG. 7 .

     In some circumstances, the user may desire to repeatedly adjust the value of the setting without performing multiple tap inputs. For example, the user may desire to increment or decrement the value of the setting multiple times without performing multiple tap inputs. In such circumstances, it may be desirable to allow the user to increase the duration between the contact input and release input of the touch input of the adjustment of the value of the setting to cause the apparatus to perform multiple increments and/or decrements of the value of the setting. In this manner, the user may be able to control the amount of increment adjustments or decrement adjustments that are performed by the apparatus by varying the duration of the touch input. 
     In at least one example embodiment, during a setting designation input, the apparatus may receive an indication of a contact input for adjustment. The apparatus may determine to perform an increment adjustment and/or a decrement adjustment of the value of the setting based, at least in part, on the contact input. In at least one example embodiment, the apparatus determines that a threshold duration has elapsed since performance of the adjustment absent receipt of the release input of the touch input for adjustment. The threshold duration may relate to a predetermined amount of time between consecutive increment and/or decrement adjustments.

If the apparatus determines that the threshold duration has not elapsed since performance of the adjustment of the value of the setting, flow returns to block  1010 . If the apparatus determines that the threshold duration has elapsed since performance of the adjustment of the value of the setting, flow returns to block  1008 . In this manner, the apparatus performs another adjustment of the value of the setting by the predetermined value based, at least in part, on the determination that the threshold duration has elapsed since performance of the adjustment absent receipt of the release input of the second touch input.
