it will be readily understood that the components of the embodiments , as generally described and illustrated in the figures herein , may be arranged and designed in a wide variety of different configurations in addition to the described example embodiments . thus , the following more detailed description of the example embodiments , as represented in the figures , is not intended to limit the scope of the embodiments , as claimed , but is merely representative of example embodiments . reference throughout this specification to “ one embodiment ” or “ an embodiment ” ( or the like ) means that a particular feature , structure , or characteristic described in connection with the embodiment is included in at least one embodiment . thus , the appearance of the phrases “ in one embodiment ” or “ in an embodiment ” or the like in various places throughout this specification are not necessarily all referring to the same embodiment . furthermore , the described features , structures , or characteristics may be combined in any suitable manner in one or more embodiments . in the following description , numerous specific details are provided to give a thorough understanding of embodiments . one skilled in the relevant art will recognize , however , that the various embodiments can be practiced without one or more of the specific details , or with other methods , components , materials , et cetera . in other instances , well known structures , materials , or operations are not shown or described in detail to avoid obfuscation . while certain devices incorporate a contoured or shaped edge , e . g ., a cylindrical edge included with a tablet computing device , when using the camera or other peripheral device with such a form factor , it is necessary to tap an existing control , e . g ., a soft control on the touch screen , to take a picture ( or perform another function associated with another peripheral device ). as may be appreciated , this is often cumbersome , especially in a single - handed use scenario . an embodiment thus provides one or more input devices , e . g ., a contoured button that is / are embedded into the shaped or contoured edge . this permits a user to simply provide a tap ( e . g ., using a thumb on the hand holding the device ) to operate a function of the device , e . g ., to take a picture using the camera . it should be noted that integration of the contoured control with the camera is just an example function for such a contoured input device . thus , another contoured input device , e . g ., a button or touch sensitive surface , optical input device , etc ., may also be used ( in addition to or in lieu of a button or like input control ) for various other functions , e . g ., depending on the state or configuration of the device , and / or application ( s ) running or active on the device , etc . the illustrated example embodiments will be best understood by reference to the figures . the following description is intended only by way of example , and simply illustrates certain example embodiments . while various other circuits , circuitry or components may be utilized in information handling devices , with regard to smart phone and / or tablet circuitry 100 , an example illustrated in fig1 includes a system on a chip or circuit design found for example in tablet or other mobile computing platforms . software and processor ( s ) are combined in a single chip or circuit 110 . processors comprise internal arithmetic units , registers , cache memory , busses , i / o ports , etc ., as is well known in the art . internal busses and the like depend on different vendors , but essentially all the peripheral devices ( 120 ) may attach to a single chip or circuit 110 . the circuitry 100 combines the processor , memory control , and i / o controller hub all into a single chip 110 . also , systems 100 of this type do not typically use sata or pci or lpc . common interfaces , for example , include sdio and i2c . there are power management chip ( s ) or circuit ( s ) 130 , e . g ., a battery management unit , bmu , which manage power as supplied , for example , via a rechargeable battery 140 , which may be recharged by a connection to a power source ( not shown ). in at least one design , a single chip or circuit , such as 110 , is used to supply bios like functionality and dram memory . system 100 typically includes one or more of a wwan transceiver 150 and a wlan transceiver 160 for connecting to various networks , such as telecommunications networks and wireless internet devices , e . g ., access points . additional devices 120 may be included , for example a camera . commonly , system 100 will include a touch screen 170 for data input and display / rendering . system 100 also typically includes various memory devices , for example flash memory 180 and sdram 190 . fig2 depicts a block diagram of another example of information handling device circuits , circuitry or components . the example depicted in fig2 may correspond to computing systems such as the thinkpad series of personal computers sold by lenovo ( us ) inc . of morrisville , n . c ., or other devices . as is apparent from the description herein , embodiments may include other features or only some of the features of the example illustrated in fig2 . the example of fig2 includes a so - called chipset 210 ( a group of integrated circuits , or chips , that work together , chipsets ) with an architecture that may vary depending on manufacturer ( for example , intel , amd , arm , etc .). intel is a registered trademark of intel corporation in the united states and other countries . amd is a registered trademark of advanced micro devices , inc . in the united states and other countries . arm is an unregistered trademark of arm holdings plc in the united states and other countries . the architecture of the chipset 210 includes a core and memory control group 220 and an i / o controller hub 250 that exchanges information ( for example , data , signals , commands , etc .) via a direct management interface ( dmi ) 242 or a link controller 244 . in fig2 , the dmi 242 is a chip - to - chip interface ( sometimes referred to as being a link between a “ northbridge ” and a “ southbridge ”). the core and memory control group 220 include one or more processors 222 ( for example , single or multi - core ) and a memory controller hub 226 that exchange information via a front side bus ( fsb ) 224 ; noting that components of the group 220 may be integrated in a chip that supplants the conventional “ northbridge ” style architecture . one or more processors 222 comprise internal arithmetic units , registers , cache memory , busses , i / o ports , etc ., as is well known in the art . in fig2 , the memory controller hub 226 interfaces with memory 240 ( for example , to provide support for a type of ram that may be referred to as “ system memory ” or “ memory ”). the memory controller hub 226 further includes a lvds interface 232 for a display device 292 ( for example , a crt , a flat panel , touch screen , etc .). a block 238 includes some technologies that may be supported via the lvds interface 232 ( for example , serial digital video , hdmi / dvi , display port ). the memory controller hub 226 also includes a pci - express interface ( pci - e ) 234 that may support discrete graphics 236 . in fig2 , the i / o hub controller 250 includes a sata interface 251 ( for example , for hdds , sdds , etc ., 280 ), a pci - e interface 252 ( for example , for wireless connections 282 ), a usb interface 253 ( for example , for devices 284 such as a digitizer , keyboard , mice , cameras , phones , microphones , storage , other connected devices , etc . ), a network interface 254 ( for example , lan ), a gpio interface 255 , a lpc interface 270 ( for asics 271 , a tpm 272 , a super i / o 273 , a firmware hub 274 , bios support 275 as well as various types of memory 276 such as rom 277 , flash 278 , and nvram 279 ), a power management interface 261 , a clock generator interface 262 , an audio interface 263 ( for example , for speakers 294 ), a tco interface 264 , a system management bus interface 265 , and spi flash 266 , which can include bios 268 and boot code 290 . the i / o hub controller 250 may include gigabit ethernet support . the system , upon power on , may be configured to execute boot code 290 for the bios 268 , as stored within the spi flash 266 , and thereafter processes data under the control of one or more operating systems and application software ( for example , stored in system memory 240 ). an operating system may be stored in any of a variety of locations and accessed , for example , according to instructions of the bios 268 . as described herein , a device may include fewer or more features than shown in the system of fig2 . information handling device circuitry , as for example outlined in fig1 or fig2 , may be used in devices that provide a contoured edge . for example , referring to fig3 , an example tablet computing device 300 is illustrated . the device 300 includes a main housing 301 that includes , e . g ., a touch screen display 302 . as illustrated in the example of fig3 , the device 300 may have a housing that is substantially quadrilateral ( e . g ., rectangular ) but also includes a contoured or shaped edge 303 , here in the form of a substantially cylindrical shaped edge 303 . the device 300 may include , according to an embodiment , one or a plurality of contoured input devices , e . g ., contoured input device 304 , incorporated into the contoured edge 303 . the example of fig3 includes a contoured input device 304 , e . g ., a ring shaped button or other device . the contoured input device 304 may accept touch based input and be formed to coordinate with the shape ( here , a contoured edge 303 that is cylindrical in form ) of the edge , which allows the contoured input device 304 to be embedded in the contoured edge 303 of such a device 300 . in the example of fig3 , it will be noted that the button 304 surface is curved or takes on a ring shape in order to match the cylinder of the contoured edge 303 . this configuration allows the button 304 to be placed in the contoured edge 303 such that it does not disrupt the aesthetic quality of the contoured edge , does not interrupt the hinged nature of the contoured edge , and additionally allows the button 304 to be pressed from various angles of approach . functionally , the button 304 may be implemented in a variety of forms , e . g ., as a mechanical or a capacitive touch switch . a mechanical form may rely on a central axis point which is moved whenever the button 304 is pressed from any angle to activate the switch . other configuration may be acceptable or preferable , e . g ., depending on the shape of the contoured edge 303 , the functionality associated with the contoured input device 304 , etc . referring to fig4 , a device 400 may include the contoured input device 404 in a location such that it is readily accessible during single handed use , as illustrated . for example , a contoured input device 404 may be located proximate to one of the ends of the contoured edge 403 such that it is readily tapped , e . g ., using a thumb . more than one contoured input device 404 may be included in the contoured edge , e . g ., to accommodate left and right handed use . for example , two contoured input devices 404 ( only one being illustrated ) may be included , such as incorporating a contoured input device 404 at opposite ends of the contoured edge 403 . alternatively , or in addition to inclusion of more than one contoured input device 304 , an embodiment may alter the functionality of the contoured input device ( s ) 404 , e . g ., based on a holding orientation ( e . g ., as sensed via positional sensors such as an accelerometer , gyroscope , and compass ), a currently running or active application , etc . for example , a contoured input device 404 may have its functionality changed , altered , removed , or adjusted depending on which hand is being used to hold the device , e . g ., as determined via mapping sensed positional inputs to a predetermined pattern of device use ( e . g ., left handed , right handed ) and / or via use selection . similarly , a particular application being used , e . g ., camera application , may change or adjust the functionality of the contoured input device 404 , e . g ., to map input received via the contoured input device 404 to an underlying application control action , e . g ., taking a picture with a camera application responsive to detecting input via the contoured input device 404 . likewise , one or more of the contoured input devices 404 may be deactivated or activated based on a variety of parameters , e . g ., holding orientation , running application ( s ), or even the physical configuration of the device , e . g ., position of a stand element 305 ( referring back to fig3 ) with respect to the housing 301 . thus , an embodiment may alter or adjust the contoured input device 404 functionality based on a variety of parameters . as will be appreciated by one skilled in the art , various aspects may be embodied as a system , method or device program product . accordingly , aspects may take the form of an entirely hardware embodiment or an embodiment including software that may all generally be referred to herein as a “ circuit ,” “ module ” or “ system .” furthermore , aspects may take the form of a device program product embodied in one or more device readable medium ( s ) having device readable program code embodied therewith . any combination of one or more non - signal device readable storage medium ( s ) may be utilized . a storage medium may be , for example , an electronic , magnetic , optical , electromagnetic , infrared , or semiconductor system , apparatus , or device , or any suitable combination of the foregoing . more specific examples of a storage medium would include the following : a portable computer diskette , a hard disk , a random access memory ( ram ), a read - only memory ( rom ), an erasable programmable read - only memory ( eprom or flash memory ), an optical fiber , a
