Title: Assisted zoom

Description:
RELATED APPLICATIONS 
     This application is related to U.S. patent application Ser. No. ______, entitled “Gesture Control”, filed on Aug. 10, 2010, and having Attorney Docket No. RPS920100038-US-NP, which is incorporated by reference herein. 
    
    
     TECHNICAL FIELD 
     Subject matter disclosed herein generally relates to techniques for controlling display of information. 
     BACKGROUND 
     A natural tendency exists for a person having difficulty seeing something on a display to move the display closer. This is particularly easy to do with a handheld display device. Physical movement, however, is not always sufficient, for example, where a user still cannot see information clearly or not always prudent, for example, where the device comes so close to a user&#39;s face that the user loses sight of his surroundings. Current zooming solutions require a user to use a manual zoom function such as touch screen, mouse click etc. on the display device to increase the relative size of the item being viewed. Such an approach requires a manual, often non-intuitive action. As described herein, various exemplary technologies provide enhanced control of zooming and optionally other display functions. 
     SUMMARY 
     An apparatus includes a planar display defining an outward pointing normal vector and an inward pointing normal vector; sensor circuitry configured to sense an initial relative position of the planar display and configured to sense a change in relative position of the planar display; and zoom circuitry configured to zoom an image presented on the planar display responsive to a change in relative position of the display sensed by the sensor circuitry where the change in relative position has a vector component along one of the normal vectors. Various other apparatuses, systems, methods, etc., are also disclosed.

     DETAILED DESCRIPTION 
     The following description includes the best mode presently contemplated for practicing the described implementations. This description is not to be taken in a limiting sense, but rather is made merely for the purpose of describing the general principles of the implementations. The scope of the described implementations should be ascertained with reference to the issued claims. 
     As mentioned, a natural tendency exists for a person having difficulty seeing information on a display to move the display closer. As described herein, an operational mode can be implemented that allows a user to amplify or otherwise control or respond to a natural, intuitive reaction (e.g., such as a user bringing a display closer to see displayed information more clearly). Such a mode can rely on one or more types of sensors. For example, sensor circuitry configured to sense a shrinking distance between a user and a device can automatically provide zooming functionality according to a zoom amplification factor, which may be selectable (e.g., scalable) by a user. In a particular example, a user could set a zooming amplification factor to 2× such that when the device moved from 60 cm to 50 cm (physical zoom is 10 cm), the device zooms the display to effectuate a “virtual” 20 cm zoom (e.g., as if the device moved from 60 cm to 40 cm). Types of sensors can include camera, proximity, light, accelerometer, audio, gyroscope, etc., for example, to provide a signal or data sufficient to determine distance between a device and a user. 
     As described herein, a device may automatically activate zoom in or out functionality based at least in part on distance between a device and an object (e.g., user head, user hand, etc.). As described herein, the functionality may depend on the information being displayed by a device, an application executing on a device, etc. For example, a device may implement a reverse-zoom to display “more” information such as for a map of a GPS application where the GPS application reacts inversely to a photo or video display application. In a GPS example, as a user moves away from a display of a device, sensor circuitry can detect the change in distance and display more geography, as if the user was flying away from the ground. 
     As described herein, in various examples, sensor circuitry of a device can be configured to sense one or more gestures. For example, sensor circuitry may be configured to distinguish movement of an object with respect to a device from movement of the device (e.g., movement of a face moving versus movement of a handheld device). 
       FIG. 1  shows various configurations of a device  100  along with some examples of sensor technology. The device  100  may be configured as a cell phone, a tablet, a camera (e.g., still, video, still and video), a GPS device or other device. The device  100  may include one or more features from at least one of the aforementioned devices. The device  100  includes particular features such as one or more processors  102 , memory  104 , power source  106 , one or more network interfaces  108 , at least one display  110  and one or more sensors  120 - 150 . 
       FIG. 1  shows an example of a sensor  120  that can detect acceleration, twist (e.g., roll, pitch, yaw) or a combination of acceleration and twist. The sensor  120  may be configured to distinguish an angle with respect to gravity. In the example of  FIG. 1 , the display  110  of the device  100  lies in a yz-plane and the sensor  120  may be configured with one or more axes coincident with the y-axis, the z-axis or both the y- and z-axes. The sensor  120  can optionally include a gyroscope and a three-axis accelerometer, which may be configured to sense motion with up to six degrees of freedom. 
       FIG. 1  also shows an example of a sensor  130  that can detect distance between the device  100  and an object (e.g., a user). The sensor  130  may rely on one or more of infrared, ultrasound, laser, or other technologies. In the example of  FIG. 1 , the sensor  130  includes an emitter and a detector, which may be configured to provide information sufficient to determine an angle and thereby a distance between the sensor  130  and an object. 
       FIG. 2  shows some examples of algorithms as associated with the sensor  120  and some examples of algorithms as associated with the sensor  130 . A method  220  includes a reception block  222  that receives one or more sensor signals, a determination block  224  to determine action based at least in part on the one or more received sensor signals and an implementation block  226  to call for implementation of action (e.g.., as determined per the determination block  224 ). In the example of  FIG. 2 , the blocks are shown along with circuitry  223 ,  225  and  227  configured to perform various functions. 
       FIG. 3  shows an example of the device  100  with zoom functionality in association with a method  320 . The display  110  of the device  100  may define an inward pointing normal (pointing into the display) and an outward pointing normal (pointing out from the display). The method  320  commences in an initiation block  322  that registers an initial state (e.g., initial position of the device  100 ). A decision block  324  decides whether a signal indicates that the device  100  has been displaced from its initial position. If no displacement is indicated, then the method  320  returns to the initiation block  322 . However, if the decision block  324  decides that displacement is indicated, then the method  320  continues to another decision block  326  that decides whether the displacement occurred along the inward pointing normal (N In ). If so, the method  320  enters a zoom out block  328  that zooms out to, for example, show more information on the display. However, if the decision block  326  decides that the indicated displacement is not along the inward pointing normal, the method  320  continues to another decision block  330  that decides whether the displacement occurred along the outward pointing normal (N Out ). If so, the method  320  continues at a zoom in block  332  that zooms in to, for example, show less information (e.g., a close-up view of a displayed image). If the decision block  330  decides that the indicated displacement is not along the outward pointing normal, the method  320  returns to, for example, the initiation block  322 . Accordingly, the method  320  may analyze one or more signals and determine whether the one or more signals indicate that movement is toward or away from a user and call for an appropriate response. While the example of  FIG. 3  shows “zoom out” for movement along the inward pointing normal (e.g., movement with a non-zero vector component along the inward pointing normal) and shows “zoom in” for movement along the outward pointing normal (e.g., movement with a non-zero vector component along the outward pointing normal), as mentioned, depending on the configuration of the device  100 , the type of information displayed or type of application displaying information, the relationships may differ from those shown. 
       FIG. 3  also shows various manners by which time may be used in conjunction with displacement. For example, as to order, a first type of displacement (e.g., down-to-up) may occur prior to a second type of displacement (e.g., left-to-right) or where a device is moved from an initial positional state (e.g., center), to an intermediate positional state (e.g., upward from center) to a final positional state (e.g., downward and forward from center). As to velocity, sensor circuitry may include a timer or other circuitry to sense or determine velocity (e.g., linear or angular or linear and angular). As to acceleration, sensor circuitry may be configured to acceleration along one or more axes, rotational directions, etc. As to stationary time, sensor circuitry may be configured to sense a pause at a position (e.g., a second to a few seconds). Stationary time may be sensed with respect to a device being placed in a dock, a stand, being placed on a table (or other horizontal surface), etc. As to a stand, the stand may be configured with a particular angle where sensing of the angle by the device (e.g., for more than a few seconds) indicates to the device that it has been placed in the stand. For example, upon placement in a stand, a device configured with cell phone circuitry may automatically switch to audio output via a speaker phone (e.g., if sensor circuitry senses an angle of 83 degrees for three seconds, switch to speaker phone). 
     As described herein, a device can include circuitry to determine whether a person is walking, driving, etc. Such circuitry may filter out walking or otherwise ignore signals associated with walking. Where a device includes camera or video circuitry, certain movement may optionally activate anti-motion circuitry to enhance quality of image capture. 
       FIG. 4  shows a device  100  with control circuitry  420  for controlling display of information on the device. The device  100  includes display  110  and cross-hairs  115  as well as thumbnails  117  and optional graphical buttons “ON” and “OFF” (e.g., positioned on opposing sides/edges of the display  110 ). As described herein, the cross-hairs  115  may be manipulated by maneuvering the device  100 . For example, the cross-hairs  115  may be located over a particular region of a displayed image to select a center for zooming or other operation. With respect to the graphical buttons, these may be “touch” activated or, for example, optionally activated via positioning of the cross-hairs  115  (e.g., to turn on or off zoom functionality). The thumbnails  117  may optionally be navigated and selected by tilting or other maneuvering of the device  100 , optionally with assist from the cross-hairs  115 . As described herein, the device  100  may be configured to respond to a tapping motion, for example, where a tap to a side of the device  100  activates an accelerometer. 
     In the example of  FIG. 4 , the control circuitry  420  includes sensor circuitry  421  for sensing, GUI(s) circuitry  422  for display and control of one or more GUIs (e.g., the on/off buttons) and cross-hairs circuitry  423  for display and control of cross-hairs  115 . The control circuitry  420  further includes control circuitry that may be application or function specific. For example, application specific circuitry  424  includes application controls, one or more application programming interfaces (APIs) and one or more GUIs. The APIs may allow for interactions between an application and sensor circuitry. Photo specific circuitry  425  includes photo controls as well as previous/next and open/close functionality that may be implemented in conjunction with thumbnails such as the thumbnails  117 . Video specific circuitry  426  includes video controls as well as play/stop/pause and forward/reverse functionality that may be implemented in conjunction with thumbnails such as the thumbnails  117 . Map specific circuitry  427  includes map controls as well as sky view and terrain view functionality, which may depend on angle of the display  110 . For example, an angle sensor (e.g., gyro or accelerometer) may sense angle of a display  110 , optionally with respect to gravity, and render a map view based at least in part on the sensed angle. In such an example, as the angle moves from the display  110  being oriented horizontally to being oriented vertically, the view may change from a sky view (e.g., overhead) to a terrain view (e.g., side or street view). 
       FIG. 5  shows an example of the device  100 , in a hand-holdable configuration, along with a method  520  that includes sensing distance between the device  100  and an object such as a user. As described herein, the device  100  may be configured to sense distance from device-to-head  526 , from head-to-device  530  or a combination of both. The method  520  commences in an initiation block  522  that registers an initial state (e.g., initial position of the device  100 ). A decision block  524  decides whether a signal indicates that the device  100  has been displaced from its initial position. If no displacement is indicated, then the method  520  returns to the initiation block  522 . However, if the decision block  524  decides that displacement is indicated, then the method  520  continues to another decision block  526  that decides whether the displacement occurred from device-to-head (i.e., the device moved toward a user&#39;s head). If so, the method  520  enters an action block  528  that performs action “A”, which may be a zoom action. However, if the decision block  526  decides that the indicated displacement is not from device-to-head (e.g., or predominantly from device-to-head), the method  520  continues to another decision block  530  that decides whether the displacement occurred from head-to-device (e.g., or predominantly from head-to-device). If so, the method  520  continues at an action block  532  that performs action “B”, which may be a zoom action different than the zoom action “A”. If the decision block  530  decides that the indicated displacement is neither sufficiently device-to-head nor head-to-device (e.g., minimal action or noise), the method  520  returns to, for example, the initiation block  522 . 
       FIG. 6  shows the device  100  configured to receive audio information and to regulate action based at least in part on received audio information. In the example of  FIG. 6 , the device  100  includes an audio sensor  140  that can sense an audio command issued by a user. As shown in  FIG. 6 , a method  620  can include regulating another method, such as the method  220 , based at least in part on sensed information. In the method  620 , a reception block  622  receives one or more signals, a determination block  624  for determining regulatory control and an implementation block  626  to call for and optionally implement regulatory control per the determination block  624 . In the example of  FIG. 6 , the blocks are shown along with circuitry  623 ,  625  and  627  configured to perform various functions. 
     In a particular example, the device  100  is configured via application circuitry to change display of information from a landscape view to a portrait view and vice-versa based on orientation of the device  100  with respect to gravity. According to the method  620 , upon sensor circuitry  623  sensing an audio command (e.g., “stop”), the regulation circuitry  627  implements a regulatory control action that disables or “stops” the landscape-portrait response of the application circuitry. With this feature disabled, the user may turn the device  100 , for example, for viewing displayed information without worrying about the device  100  automatically shifting the display from landscape to portrait or vice-versa. 
     In the foregoing example, two different types of phenomena are sensed where sensation of an audio phenomenon regulates a response to a spatial phenomenon. As described herein, in an alternative arrangement, a spatial movement may regulate another spatial movement. For example, a quick roll of the device  100  (e.g., about a z-axis) may be sensed by sensor circuitry and regulate a pre-determined response a different spatial movement such as a 90 degree rotation (e.g., about an x-axis). Spatial movement may be distinguished based on one or more characteristics such as pitch, yaw or roll, velocity, acceleration, order, etc. As to order, a spatial input may include, for example, movement from (a) right-to-left or (b) left-to-right or (c) top-left to top-right to bottom-right, etc. Combinations of phenomena may be sensed as well (e.g., consider sensing an audio command in combination with sensing a top-right position of a device). Combinations may aid in registering sensed input or defining a coordinate space relative to a device. 
       FIG. 7  shows a device  100  configured with one or more types of sensor circuitry  120 ,  130 ,  140 ,  150  and  160 , application circuitry  180  and regulation circuitry  190 . As indicated, the device  100  may include signal interfaces or other circuitry such that multiple types of sensor signals can be combined, for example, per the multi-sensor input circuitry  160 . For example, a signal from the sound sensor circuitry  140  may be combined with a signal from the proximity sensor circuitry  130  to provide sensed information suitable for the application circuitry  180  or the regulation circuitry  190  to respond or regulate. In this example, a user may speak the word “out” while moving the device  100  in a direction along the outward normal (e.g., to the user&#39;s head). The circuitry may sense the utterance (e.g., using voice recognition circuitry) and sense the change in proximity to the user and cause an application to zoom out. Similarly, where a user speaks the word “in”, the device  100  may sense the utterance and sense the change in proximity and cause an application to zoom in. Such a device may be programmed to zoom “out” or “in” regardless of whether the change is proximity is away from or toward a user (e.g., whether along an inward or outward normal direction). In other words, the sensed utterance may control the type of zoom regardless of direction toward/away where the zoom, whether in or out, occurs in some proportion to a change in proximity (or distance, etc.). The foregoing example is illustrative of some features as other types of sensor input and responses or regulation of responses may be programmed. 
     In the example of  FIG. 7 , the sensor circuitry  140  is shown as being configured to sense audio (e.g., spoken commands) and the sensor circuitry  150  is shown as being configured to capture images such as an image of a user. Image analysis circuitry may be configured to determine one or more metrics for calculation of a distance between the device and the user (e.g., to determine proximity to a user). 
     The application circuitry  180  can include one or more pre-existing application responses to sensed information, whether sensed information based on a single sensor or multiple sensors. For example, an application may be configured to switch from a landscape to a portrait view on a display based on sensed information that indicates the device has been rotated. The regulation circuitry  190  may be configured to regulate such responses based on sensed information. For example, where a device senses a quick rotation about an axis (e.g., long axis in portrait view or long axis in landscape view), such sensed information may act to disable the application circuitry&#39;s response to rotation about a different axis (e.g., rotation about an axis that rotates a long axis of a display such as the z-axis of the display  110  of  FIG. 1 ). 
     As described herein, an apparatus such as the device  100  of  FIG. 1 , can include a planar display defining an outward pointing normal vector and an inward pointing normal vector, sensor circuitry configured to sense an initial relative position of the planar display and configured to sense a change in relative position of the planar display, and zoom circuitry configured to zoom an image presented on the planar display responsive to a change in relative position of the display sensed by the sensor circuitry wherein the change in relative position comprises a vector component along one of the normal vectors. An example of such a device is shown with respect to  FIG. 3 . Referring to the method  220  of  FIG. 2 , circuitry  225  may be configured to determine that a zoom action should occur and circuitry  227  may be configured as zoom circuitry to implement the called for zoom action. 
     As described herein, a device may include control circuitry configured to control zoom circuitry based at least in part on relative rotational position of a display of the device about a normal vector of the display (e.g., as sensed by sensor circuitry). A device may include control circuitry configured to control zoom circuitry based at least in part on at least one or more of a relative pitch position of a display as sensed by sensor circuitry, a relative yaw position of a display as sensed by sensor circuitry and a relative roll position of a display as sensed by sensor circuitry. For example, control circuitry may be configured to disable zoom circuitry based at least in part on relative position of a display as sensed by sensor circuitry. In various examples, sensor circuitry may be configured to define a three-dimensional coordinate system, optionally with respect to gravity. In various examples, a relative position of a display may be a relative position determined, at least in part, with respect to gravity. A device may include a camera as sensor circuitry to determine, in part, proximity of a planar display to an object and an accelerometer as sensor circuitry to determine, in part, a direction of Earth&#39;s gravity with respect to orientation of the planar display. A device may include a positioning system sensor (e.g., GPS) as sensor circuitry. 
     As described herein, a method can include sensing a change in relative position of a planar display where the change includes a vector component along an outward pointing normal vector defined by the planar display; responsive to the change, zooming an image displayed on the planar display; sensing a change in relative position of the planar display where the change includes a vector component along an inward pointing normal vector defined by the planar display; and, responsive to the change, zooming an image displayed on the planar display. For example,  FIG. 3  shows a method  320  where zooming an image displayed on a planar display occurs when a change in relative position of the planar display occurs in a direction with a vector component along an inward pointing normal vector or in a direction with a vector component along an outward pointing normal vector. In  FIG. 5 , an example of a device  100  is shown along with a method  520  where relative position pertains, at least in part, to proximity (e.g., to a user&#39;s head). Hence, a method may include sensing proximity of a planar display to an object. 
     As described herein, one or more computer-readable media can include processor-executable instructions to instruct a processor to: zoom an image displayed on a planar display, responsive to a sensed change in relative position of the planar display where the change includes a vector component along an outward pointing normal vector defined by the planar display; and zoom an image displayed on the planar display, responsive to a sensed change in relative position of the planar display where the change includes a vector component along an inward pointing normal vector defined by the planar display. 
     As described herein, an apparatus such as the device  100  of  FIG. 1  can include sensor circuitry configured to sense spatial phenomena; application circuitry configured to respond to sensation of a spatial phenomenon by the sensor circuitry where a pre-existing relationship exists between the spatial phenomenon and the response of the application circuitry; and regulation circuitry configured to regulate the response of the application circuitry to the spatial phenomenon based at least in part on sensation of a different spatial phenomenon by the sensor circuitry. For example,  FIG. 7  shows various types of sensor circuitry  120 ,  130 ,  140 ,  150  and  160  as well as application circuitry  180  and regulation circuitry  190 . The application circuitry  180  may rely on one or more pre-existing relationships to respond to sensed information and the regulation circuitry  190  may regulate a response or responses based on sensed information. For example, the sensor circuitry  140  may sense audio and the sensor circuitry  150  may sense video. Sensed information from such circuitry may cause the device  100  to respond where the response is regulated by sensed video information. 
     As described herein, regulation circuitry may be configured to disable response of application circuitry to spatial phenomenon, for example, responsive to sensation of the different spatial phenomenon. For example, a yaw motion of the device  100  (e.g., top away) may disable zooming along an inward or outward pointing normal vector (e.g., as defined by a display). Similarly, regulation circuitry may be configured to enable response of application circuitry to spatial phenomenon, for example, responsive to sensation of different spatial phenomenon. For example, a yaw motion of the device  100  may act as an on/off switch for zooming. In such an example, the same yaw motion may be used for on and off or different yaw motions may be used (e.g., top away is “on” and bottom away is “off”). 
     As described herein, a spatial phenomenon may be differentiated from another spatial phenomenon based on time (e.g., a time dependency). For example, a time dependency may be a velocity or acceleration where a slow, steady movement registers as one spatial phenomenon and a fast, accelerating movement registers as another, different spatial phenomenon. A spatial phenomenon may depend on movement of an object with respect to a device (e.g., user moving head toward the device). As described herein, a device may be a mobile phone, a tablet, a notebook, a slate, a pad, a personal data assistant, a camera, or a global positioning system device. A device may optionally include features of one or more such devices (e.g., mobile phone with GPS and camera). 
     As described herein, a device can include first sensor circuitry configured to sense a first type of physical phenomena; second sensor circuitry configured to sense a second type of physical phenomena; and application circuitry configured to respond to sensation of physical phenomena by the first sensor circuitry and the second sensor circuitry where a pre-existing relationship exists between physical phenomena of the first type and the second type and the response of the application circuitry.  FIG. 7  shows the multiple input circuitry  160  as being configured to combine first and second sensor circuitry inputs. Such inputs may be based on sensed distance, sound, light, acceleration or other physical phenomena. 
     As described herein, a method can include displaying information to a display; sensing a first physical phenomena; redisplaying information responsive to the sensing of the first physical phenomena where a pre-existing relationship exists between the first physical phenomena and the redisplaying of information; sensing a second physical phenomena; and, responsive to the sensing of the second physical phenomena, regulating the pre-existing relationship between the first physical phenomena and the redisplaying of information. For example,  FIG. 4  shows a device  100  configured with control circuitry that may zoom an image responsive to sensed proximity to a user. In this example, a roll motion of the device  100  (e.g., a rotation) may cause one of the thumbnail images to be displayed as the main image (e.g., roll right selects next thumbnail image to the right of the currently displayed main image for display as the main image and roll left selects next thumbnail image to the left of the currently displayed main image for display as the main image). A rotation may be followed by a change in relative spatial position or a change in relative spatial position may be followed by a rotation. In such an example, a user can readily navigate multiple images (e.g., displayed thumbnails or yet to be displayed images) and zoom in and out, as desired. While spatial motions are mentioned, one or more audio commands may be used, for example, to zoom or to select a different image for display as a main image (e.g., consider audio commands such as “in”, “out”, “next”, “previous”, “forward”, “back”, etc.). 
     As described herein, a device may be programmed to perform a method where redisplaying information includes orientating the information to maintain a prior, relative orientation of the information, for example, where the prior, relative orientation may be a landscape orientation or a portrait orientation. 
     As described herein, a method can include sensing movement; responsive to sensing of movement, altering display of information on an apparatus; sensing different movement; and responsive to sensing of different movement disabling the altering. In such a method, sensing movement may include sensing movement of the apparatus and sensing different movement may include sensing movement of an object with respect to the apparatus (or vice versa). In such an example, sensing different movement may depend on time (e.g., optionally velocity or acceleration or one or more other time based factors). 
       FIG. 8  shows a device  100  with an example of a graphical user interface  800 . The GUI  800  includes various control graphics such as “zoom enable” and “zoom disable”. According to the example of  FIG. 8 , the GUI  800  includes check box graphics that a user may select to associate some physical phenomenon with the zoom enable or disable functions. Specifically, the GUI  800  shows movements including yaw back/forward and roll right/left as well as physical touch or cursor activatable right/left buttons. Thus, for the example of  FIG. 8 , if a user wanted to enable zoom, the user would perform a “yaw back” maneuver of the device (e.g., tilt top edge back in the example of  FIG. 4 ) and if a user wanted to disable zoom, the user would perform a “yaw front” maneuver of the device (e.g., tilt top edge forward in the example of  FIG. 4 ). Other options may exist to enable and disabled zoom such as a touchscreen gesture, a touchscreen button (see, e.g., on/off buttons in the example of  FIG. 4 ), one or more hardware buttons, voice command, other gesture of the device, etc. As to “zoom max”, “zoom min”, “zoom start” and “zoom stop”, the GUI  800  includes slidebars that allow for user input. The GUI  800  also includes unit selection (e.g., US units or metric units). Yet additional features include “zoom acceleration” and “head-to-device lock”. Zoom acceleration may zoom based in part on sensed acceleration (e.g., more zoom with more acceleration) while head-to-device lock may sense movement of a head toward a device and cause a display to prohibit zoom (e.g., to lock the display). Further, the GUI  800  may display a list of applications, for example, with check boxes that allow a user to associate controls with one or more applications. While a single set screen (e.g., GUI) is shown in the example of  FIG. 8 , a device may be configured with multiple set screens where each screen sets control parameters for one or more applications. For example, one set screen may call for use of button controls to enable/disable zoom for one application (e.g., where device gesture control may distract from use of the application) and another set screen may call for use of roll controls to enable/disable zoom for another application. Accordingly, a GUI can be configured to receive input to tailor zoom control parameters for an application or groups of applications and a series of such GUIs can allow for applications or groups of applications to have different zoom control parameters (e.g., text applications have settings X while image applications have settings Y). 
     In  FIG. 8 , the device  100  includes one or more sensors  111 , an operating system  112 , one or more APIs  113  and one or more applications  114 . For example, a sensor may be a hardware device controlled by an operating system where one or more APIs allow an application to access data acquired by the sensor. As described herein, an API may optionally allow an application to control a sensor (e.g., set gain, functionality, etc.). Some examples of APIs include an auto-rotate API, a camera/video API, a sound API, and a display API. For example, an application may call a camera API to access camera data to determine head-to-device distance and call a display API to control a display (e.g., to control rendering functionality for rendering information to the display). 
     As described herein, various acts, steps, etc., can be implemented as instructions stored in one or more computer-readable media. For example, one or more computer-readable media can include computer-executable instructions to instruct a processor: to zoom an image displayed on a planar display, responsive to a sensed change in relative position of the planar display along an outward pointing normal direction and to zoom an image displayed on the planar display, responsive to a sensed change in relative position of the planar display along an inward pointing normal direction. 
     In another example, one or more computer-readable media can include computer-executable instructions to instruct a processor: to sense a first type of physical phenomena, to sense a second type of physical phenomena, to respond to sensation of a physical phenomenon of the first type where a pre-existing relationship exists between the physical phenomenon of the first type and the response, and to regulate the response to the physical phenomenon of the first type based at least in part on sensation of a physical phenomenon of the second type. 
     The term “circuit” or “circuitry” is used in the summary, description, and/or claims. As is well known in the art, the term “circuitry” includes all levels of available integration, e.g., from discrete logic circuits to the highest level of circuit integration such as VLSI, and includes programmable logic components programmed to perform the functions of an embodiment as well as general-purpose or special-purpose processors programmed with instructions to perform those functions. 
     While various exemplary circuits or circuitry have been discussed,  FIG. 9  depicts a block diagram of an illustrative example of a computer system  900 . The system  900  may be a desktop computer system, such as one of the ThinkCentre® or ThinkPad® series of personal computers sold by Lenovo (US) Inc. of Morrisville, N.C., or a workstation computer, such as the ThinkStation®, which are sold by Lenovo (US) Inc. of Morrisville, N.C.; however, as apparent from the description herein, a device may include other features or only some of the features of the system  900 . 
     As shown in  FIG. 9 , the system  900  includes a so-called chipset  910 . A chipset refers to a group of integrated circuits, or chips, that are designed to work together. Chipsets are usually marketed as a single product (e.g., consider chipsets marketed under the brands INTEL®, AMD®, etc.). 
     In the example of  FIG. 9 , the chipset  910  has a particular architecture, which may vary to some extent depending on brand or manufacturer. The architecture of the chipset  910  includes a core and memory control group  920  and an I/O controller hub  950  that exchange information (e.g., data, signals, commands, etc.) via, for example, a direct management interface or direct media interface (DMI)  942  or a link controller  944 . In the example of  FIG. 9 , the DMI  942  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  920  include one or more processors  922  (e.g., single core or multi-core) and a memory controller hub  926  that exchange information via a front side bus (FSB)  924 . As described herein, various components of the core and memory control group  920  may be integrated onto a single processor die, for example, to make a chip that supplants the conventional “northbridge” style architecture. 
     The memory controller hub  926  interfaces with memory  940 . For example, the memory controller hub  926  may provide support for DDR SDRAM memory (e.g., DDR, DDR2, DDR3, etc.). In general, the memory  940  is a type of random-access memory (RAM). It is often referred to as “system memory”. 
     The memory controller hub  926  further includes a low-voltage differential signaling interface (LVDS)  932 . The LVDS  932  may be a so-called LVDS Display Interface (LDI) for support of a display device  992  (e.g., a CRT, a flat panel, a projector, etc.). A block  938  includes some examples of technologies that may be supported via the LVDS interface  932  (e.g., serial digital video, HDMI/DVI, display port). The memory controller hub  926  also includes one or more PCI-express interfaces (PCI-E)  934 , for example, for support of discrete graphics  936 . Discrete graphics using a PCI-E interface has become an alternative approach to an accelerated graphics port (AGP). For example, the memory controller hub  926  may include a 16-lane (×16) PCI-E port for an external PCI-E-based graphics card. An exemplary system may include AGP or PCI-E for support of graphics. 
     The I/O hub controller  950  includes a variety of interfaces. The example of  FIG. 9  includes a SATA interface  951 , one or more PCI-E interfaces  952  (optionally one or more legacy PCI interfaces), one or more USB interfaces  953 , a LAN interface  954  (more generally a network interface), a general purpose I/O interface (GPIO)  955 , a low-pin count (LPC) interface  970 , a power management interface  961 , a clock generator interface  962 , an audio interface  963  (e.g., for speakers  994 ), a total cost of operation (TCO) interface  964 , a system management bus interface (e.g., a multi-master serial computer bus interface)  965 , and a serial peripheral flash memory/controller interface (SPI Flash)  966 , which, in the example of  FIG. 9 , includes BIOS  968  and boot code  990 . With respect to network connections, the I/O hub controller  950  may include integrated gigabit Ethernet controller lines multiplexed with a PCI-E interface port. Other network features may operate independent of a PCI-E interface. 
     The interfaces of the I/O hub controller  950  provide for communication with various devices, networks, etc. For example, the SATA interface  951  provides for erasing, reading and writing information on one or more drives  980  such as HDDs, SDDs or a combination thereof. The I/O hub controller  950  may also include an advanced host controller interface (AHCI) to support one or more drives  980 . The PCI-E interface  952  allows for wireless connections  982  to devices, networks, etc. The USB interface  953  provides for input devices  984  such as keyboards (KB), mice and various other devices (e.g., cameras, phones, storage, media players, etc.). 
     In the example of  FIG. 9 , the LPC interface  970  provides for use of one or more ASICs  971 , a trusted platform module (TPM)  972 , a super I/O  973 , a firmware hub  974 , BIOS support  975  as well as various types of memory  976  such as ROM  977 , Flash  978 , and non-volatile RAM (NVRAM)  979 . With respect to the TPM  972 , this module may be in the form of a chip that can be used to authenticate software and hardware devices. For example, a TPM may be capable of performing platform authentication and may be used to verify that a system seeking access is the expected system. 
     The system  900 , upon power on, may be configured to execute boot code  990  for the BIOS  968 , as stored within the SPI Flash  966 , and thereafter processes data under the control of one or more operating systems and application software (e.g., stored in system memory  940 ). An operating system may be stored in any of a variety of locations and accessed, for example, according to instructions of the BIOS  968 . Again, as described herein, an exemplary device or other machine may include fewer or more features than shown in the system  900  of  FIG. 9 . For example, the device  100  of  FIG. 1  may include some or all of the features shown in the system  900  (e.g., as part of basic or control circuitry).
