Augmented reality is an intuitive and convenient way for displaying information to a user of a mobile device. Examples of mobile devices include a personal display assistant (“PDA”), a cellular phone, a portable digital music player, a laptop computer, or other mobile device. In general, augmented reality is a method of displaying both real-world environmental elements layered with computer-generated graphical elements. Using a mobile device, computer-generated information that is relevant to the environment may be displayed alongside or atop the actual environment so as to minimize interrupting an ongoing task or by minimizing the change in context and the amount of attention required from the user.
However, instructing a mobile device to display an augmented reality video or image can be an awkward process. For example, the mobile device may require that the user push a hardware or software button for switching between the standard operating functionality of the mobile device and an augmented reality mode. To complicate the switch, the mobile device may have tiny buttons that may or may not have tactile feedback for entering input. The mobile device may also have other challenging elements, such as requiring the user to open a cover or flip a switch. When the mobile device is being used in an ongoing activity, switching between entering input on the buttons of the mobile device and the augmented reality display mode can be a tiresome, strenuous, and annoying activity.
Although there are some existing arrangements that address switching between the standard functionality of the mobile device and the augmented reality mode, these existing arrangements require the user to locate and activate a software button or physical element to switch between modes. The requirement to press an additional button or screen element creates an interruption between the user's input and the output from the mobile device. Not only is the interruption jarring and not conducive to an ongoing task, but the user interaction of pressing an element itself is a suboptimal method for switching between modes.
A system and method for switching between an operational mode of a mobile device from a first operational mode to a second operational mode using a natural motion gesture is provided. In one implementation, the system includes a storage device operative to store a first set of baseline data representative of a first state of a mobile device and further operative to store a second set of baseline data representative of a second state of a mobile device.

Moreover, the processor is further operative to change the operational mode of the mobile device from the first mode to the second mode when the timing data approximates the transitional timing data.
In yet another aspect of the system, the processor is further operative to output a result in response to the input received during the first operational mode, and the at least one computer-generated graphic element comprises a portion of the result output by the processor.
In yet a further aspect of the system, the selected portion of the real-world environment surrounding the mobile device is recorded in real-time. In another aspect of the system, the selected portion of the real-world environment surrounding the mobile device was previously recorded and stored in the storage device.

The magnetic sensor 104 is operative to detect the magnetic field near the mobile device 102. The magnetic sensor 104 is one example of an orientation sensor employed by the mobile device 102 for determining the orientation of the mobile device 102. The magnetic sensor 104 may include a geomagnetism detection type electronic compass integrated circuit or other type of electronic compass. The magnetic sensor 104 may further include one or more magnetic sensors for detecting geomagnetism in three-dimensions, such as along an X-axis, a Y-axis, and a Z-axis. Moreover, the magnetic sensor 104 may include an arithmetic circuit for processing the signal from each sensor. In addition, the magnetic sensor 104 may output the magnetic measured values as 8-bit digital values to another component of the mobile device 102 for further processing, such as the processor 124. In one implementation, the magnetic sensor 104 is an AK8973, available from Asahi Kasei Microsystems Co., Ltd., headquartered in Tokyo, Japan.
The accelerometer 106 is operative to detect accelerations and motion of the mobile device 102. The accelerometer 106 is another example of an orientation sensor employed by the mobile 102 for determining the orientation of the mobile device 102. The accelerometer 106 may include a digital output 3-axis linear accelerometer packaged in a Land Grid Array (“LGA”) package. The accelerometer 106 may further include a sensing element and an integrated circuit interface operative to process information from the sensing element and to output a signal representative of the movement of the mobile device 102 through an I2C/SPI serial interface. The accelerometer 106 may be operative to detect the motion of the mobile device 102 through one or more dimensions, such as the X-axis, Y-axis, and Z-axis. In one implementation, the accelerometer 106 may be an LIS331DLE, available from STMicroelectronics, headquartered in Geneva, Switzerland.
The camera 108 is operative to capture images, such as video or still images, of the environment in which the mobile device 102 operates. The camera 108 may be operative to capture images in real-time or for storage and later retrieval. The camera 108 may be a digital camera operative to capture the video or the still images at a selected framerate, resolution, megapixel size, or other digital camera characteristic. The camera 108 may be further operative to output the images of the environment to the processor 124 for additional manipulation or processing. Moreover, the images recorded by the camera 108 may be displayed on the display 112 in real-time, or displayed on the display 112 at a later time when requested by the processor 124 or a user. In addition, the camera 108 may be activated based on a natural motion gesture of the mobile device 102. As explained below, when the camera 108 is activated by way of a natural motion gesture, the processor 124 may overlay computer-generated graphic elements on the images recorded by the camera 108 and display the resulting composite images on the display 112 as an augmented reality image and/or video.
The display 112 is operative to display images for the mobile device 102. The display 112 may be an interactive display, such as a capacitive or resistive display, and operative to receive input from the user when the user touches the display 112. The display 112 may also display images recorded by the camera 108 or display computer-generated graphic elements generated by the processor 124. Moreover, as mentioned above, the display 112 may be operative to display images recorded by the camera 108 overlaid with computer-generated graphic elements generated by the processor 124. In addition, when the camera 108 is activated by way of the natural motion gesture, the display 112 may also become active to display the images recorded by the camera 108 overlaid with the computer-generated graphic elements generated by the processor 124.
The input interface 110 is output to receive input from a user. The input interface 110 may be a touch-based interface, such as a keyboard or the display 112, or the input interface 110 may be an audio interface, such as a microphone. The input interface 110 may also be a combination of touch-based and audio-based interfaces. The input received by the input interface 110 may be sent to the processor 124 for additional processing. Moreover, the input received by the input interface 110 may cause the mobile device 102 to enter a first operational mode whereby the mobile device 102 is operative to receive voice and/or audio input via the input interface 110. For example, the input interface 110 may receive an input that instructs the processor 124 to start a selected mobile application, and the start-up of the mobile application may cause the mobile device 102 to enter this first operational mode.
The processor 124 is operative to process data sent by the components of the mobile device 102, such as the magnetic sensor 104, the accelerometer 106, the camera 108, and so forth. Moreover, the processor 124 may be operative to send output to one or more components of the mobile device 102 such as the memory storage device 114, the display 112, or other components of the mobile device 102.
The processor 124 may be further operative to implement a software-based orientation sensor for determining the orientation of the mobile device 102. For example, the magnetic sensor 104 and the accelerometer 106 may output their readings to the processor 124, which may then interpolate the data from the magnetic sensor 104 and the accelerometer 106 to determine the orientation of the mobile device 102. The processor 124 may be programmed or calibrated with a selected plane for determining the orientation of the mobile device 102, such as being programmed or calibrated with a horizontal plane and magnetic north. However, the processor 124 may alternatively be programmed or calibrated with another plane for determining the orientation of the mobile device 102, such as a vertical plane. As discussed below, the processor 124 may use the determined orientation of the mobile device 102 to determine whether a natural motion gesture has been made to switch the operating mode of the mobile device 102 from an input mode to an augmented reality mode. Depending on the information stored in the memory storage device 114, the processor 124 may make other determinations about changing the operating mode of the mobile device 102 as well.
In addition to making determinations about the orientation of the mobile device 102, the processor 124 may be further operative to determine when to make the orientation determinations. In one implementation, the processor 124 is operative to continuously make determinations about the orientation of the mobile device 102. For example, when the mobile device 102 is turned on (e.g., being used by the user), the processor 124 may be operative to determine the orientation of the mobile device 102 until the mobile device 102 is turned off or put into a non-operating mode, such as a hibernation mode or “sleep” mode.
Alternatively, the processor 124 may be operative to determine the orientation of the mobile device 102 at selected occurrences or between selected occurrences. An example of a selected occurrence is the initialization of a mobile application, such as the start of a mobile search application, a mobile web browser application, a mobile Global Positioning System (“GPS”) navigation application, or other mobile application. In this implementation, the processor 124 may be operative to determine an initial orientation of the mobile device 102 when the mobile application is initialized. After the initialization of the mobile application, the processor 124 may then continuously make determinations about the orientation of the mobile device 102. In addition to starting the determinations of the orientation of the mobile device 102, a selected occurrence may stop the determinations of the orientation of the mobile device 102. For example, when the orientation of the mobile device 102 matches, or is approximate to, a previously programmed or calibrated orientation, the processor 124 may stop making the determinations of the orientation of the mobile device 102.
In yet a further implementation, the processor 124 may be operative to make determinations about the orientation of the mobile device 102 at selected time intervals. For example, the processor 124 may be operative to determine the orientation of the mobile device 102 at 5 millisecond intervals, 10 second intervals, or any other measurement of time intervals. In this implementation, the processor 124 may start the determinations of the mobile device 102 at the initialization of the mobile application and then, afterwards, determine orientations of the mobile device 102 at selected time intervals until a selected, second occurrence occurs that would stop the determinations of the orientations of the mobile device 102. As discussed below, the selected, second occurrence may include the initialization of a second mobile application or the determination that the orientation of the mobile device 102 matches, or is approximate to, a previously programmed or calibrated orientation.
The memory storage device 114 is operative to store one or more datasets 116/118/120/122 to assist the processor 124 in determining whether the user has made a natural motion gesture with the mobile device 102 that should cause the processor 124 to change the operational mode of the mobile device 102. The datasets 116/118/120/122 may represent data for three components that define a vector space in three dimensions. However, additional components are also possible. Moreover, the components that define the vector space may have a particular arrangement, such as by being orthogonal or approximately orthogonal. Other arrangements are also possible.
In one implementation, the memory storage device 114 is operative to store a first set of baseline data 116 representative of the orientation of the mobile device 102 in an input receiving mode, such as a voice input mode. The voice input mode of the mobile device 102 may be a mode in which the mobile device 102 accepts speech input via the input interface 110, where the input interface 110 may be a microphone or other audio input interface. A mobile application, such as a mobile search application or a mobile GPS navigation application, may use the speech input to perform a search requested by the user or to find a location requested by the user. Other operations using the speech input are also possible.
The first set of baseline data 116 represents a first state of the mobile device 102. The first state of the mobile device 102 may include any state of the mobile device 102, such as being in a selected operating mode, in a selected orientation, when a selected mobile application is initialized, when a selected mobile application is exited, or any combinations of states of the mobile device 102. In one implementation, the first state of the mobile device 102 is when the mobile device 102 is placed in a voice input operational mode. The mobile device 102 may enter the voice input operational mode when a mobile application is initialized. Alternatively, the mobile device 102 may enter the voice input operational mode when the mobile device 102 is in a selected orientation.
The first set of baseline data 116 may describe the first state of the mobile device 102 in terms of orientation. The first set of baseline data 116 may describe the orientation of the mobile device 102 in terms of pitch, yaw, roll or other types of orientation. As discussed above, the first set of baseline data 116 may include one or more components that are approximately orthogonal that define vectors in a three-dimensional space. In addition, the first set of baseline data 116 may be calibrated or configured such that the first state of the mobile device 102 is recognized as being in a state proximate to a user's head and mouth. For example, the memory storage device 114 may be initially programmed with a first set of baseline data 116 approximating the orientation of the mobile device 102 when placed next to a user's head and mouth, head and ear, or in another position for accepting speech or voice input from the user.
Moreover, the first set of baseline data 116 may represent the first state of the mobile device 102 at the time a mobile application is initialized. For example, the first set of baseline data 116 may represent the first state of the mobile device 102 as being in a state when a mobile search application is initialized. Furthermore, the first set of baseline data 116 may encompass more than one state of the mobile device 102, such as by including data representative of the mobile device 102 being in a state when a mobile application is initialized and then being in a selected orientation when, or after, the mobile application is initialized.
The memory storage device 114 may be further operative to store a second set of baseline data 120 representative of the mobile device 102 being in a second state. The second state of the mobile device 102 may include any state of the mobile device 102, such as being in a selected operating mode, in a selected orientation, when a selected mobile application is initialized, when a selected mobile application is exited, or any combinations of states of the mobile device 102.
In one implementation, the second state of the mobile device 102 is when the mobile device 102 is placed in a visual display mode, such as an augmented reality display mode. The mobile device 102 may enter the augmented reality display mode when a mobile application is initialized. Alternatively, the mobile device 102 may enter the augmented reality display mode when the mobile device 102 is in a selected second orientation. The second set of baseline data 120 may represent the mobile device 102 being in the selected second orientation. In one implementation, the second set of baseline data 120 approximates the mobile device 102 being in an orientation relatively perpendicular to a flat surface, such as the ground. The augmented reality display mode may include displaying an image on the display 112, where the image is being, or has been previously, recorded by the camera 108 overlaid with a computer-generated graphic element representative of an output, such as a search result, prepared in response to an input received during the voice input operational mode. As discussed below, in this implementation, the processor 124 may be operative to activate the camera 108 and the display 112 when the processor 124 determines that the orientation of the mobile device 102 approximates the orientation represented by the second set of baseline data 120.
The memory storage device 114 may be further operative to store a third set of baseline data 122 representative of the mobile device 102 being in a third state. The third state of the mobile device 102 may include any state of the mobile device 102, such as being in a selected operating mode, in a selected orientation, when a selected mobile application is initialized, when a selected mobile application is exited, or any combinations of states of the mobile device 102. In one implementation, the third state of the mobile device 102 is when the mobile device 102 is placed in another visual display mode, such as a reading display mode. The mobile device 102 may enter the reading display mode when a mobile application is initialized. Alternatively, the mobile device 102 may enter the reading display mode when the mobile device 102 is in a selected third orientation. In one implementation, the third set of baseline data 122 approximates the mobile device 102 being in an orientation forming an approximate acute angle with a flat surface, such as the ground. Moreover, the third set of baseline data 122 may approximate the mobile device 102 being in an orientation other than an orientation where the mobile device 102 is approximately perpendicular with a flat surface. The reading display mode may include displaying display one or more outputs on the display 112 in response to an input received during the voice input operational mode. The reading display mode may differ from the augmented reality display mode in that camera may not be activated 108 when the mobile device 102 is placed in the reading display mode. As discussed below, in this implementation, the processor 124 may be operative to active the display 112 when the processor 124 determines that the orientation of the mobile device 102 approximates the orientation represented by the third set of baseline data 122.
To facilitate the detection of the transition between the various operational modes, the memory storage device 114 may include transitional orientation data 118 representative of approximated transitional orientations that the mobile device 102 may take on as the mobile device 102 moves from one orientation for a first operational mode to a second orientation for a second operational mode. The transitional orientation data 118 may be based on calibrating the mobile device 102 with approximated orientations that the mobile device 102 may take on as it transitions between various operational modes. Alternatively, a user may calibrate the transitional orientation data 118 by moving the mobile device 102 through various orientations from the various operational modes and recording the orientations as the transitional orientation data 118. In another implementation, the transitional orientation data 118 may be programmed by interpolating the potential orientations that the mobile device 102 may take on as the mobile device 102 transitions orientations between operating modes.
Moreover, the transitional orientation data 118 may include various sets of transitional orientation data 118 based on the starting state and ending state of the mobile device 102. For example, the transitional orientation data 118 may include a first set of transitional orientation data for the orientations that the mobile device 102 may take on as the mobile device 102 transitions between the voice input operational mode and the augmented reality display mode, and the transitional orientation data 118 may include a second set of transitional orientation data for the orientations that the mobile device may take on as the mobile device 102 transitions between the voice input operational mode and the reading display mode. The transitional orientation data 118 may also include a third set of transitional orientation data for the orientations of the mobile device 102 as the mobile device 102′ transitions between the augmented reality display mode and the reading display mode, or vice versa. In other words, the transitional orientation data 118 may include any set of transitional orientation data as the mobile device 102 transitions from a first state to a second state.
The transitional timing data 202 may include timing data sets that represent approximate durations between various states. For example, the transitional timing data 202 may include a first set of timing data that represents the approximate duration that the mobile device 102′ should spend in changing from the orientation of the voice input mode to the augmented reality display mode. In this first example, the first set of timing data may represent that the approximate duration between the voice input mode and the augmented reality display mode is five seconds. As a second example, the transitional timing data 202 may also include a second set of timing data that represents the approximate duration that the mobile device 102′ should spend in changing from the orientation of the voice input mode to the reading display mode. In this second example, the second set of timing data may represent that the approximate duration between the voice input mode and the reading display mode is eight seconds. that the mobile device 102′ should be in a second state ten seconds after leaving the first state.
Based on the foregoing two examples, the processor 124 may refer to the transitional timing data 202 to determine whether to switch the operational mode of the mobile device 102′. In one implementation, and with reference to the prior two examples, the processor 124 may first determine that the mobile device 102′ is in the voice input mode and then, after an approximate five seconds, determine whether the mobile device 102′ is in an approximate orientation for the augmented reality display mode. If the processor 124 determines that the mobile device 102′ is in an approximate orientation for the augmented reality display mode, the processor 124 may change the operational mode of the mobile device 102′ from the voice input mode to the augmented reality display mode. However, if the mobile device 102′ is not in the approximate orientation for the augmented reality display mode, the processor 124 may then wait for an additional approximate three seconds to determine whether the mobile device 102′ is in an approximate orientation for the reading display mode. If the processor 124 determines that the mobile device 102′ is in an approximate orientation for the reading display mode, the processor 124 may switch the operational mode of the mobile device 102′ from the voice input mode to the reading display mode. Additional sets of timing data may be added to the transitional timing data 202 for representing approximate durations between other states of the mobile device 102′ as well.
With reference to
In one implementation, when the processor 124 determines that the orientation of the mobile device 102 approximates the orientation of the orientation represented by the first baseline dataset 116 (e.g., the orientation of the mobile device 102 is adjacent to the user's head for receiving voice input data from the user), the mobile device 102 may then start monitoring the transitional orientations of the mobile device 102 as the user moves the mobile device 102 from the voice input mode orientation. During this transitional phase, the processor 124 may compare the transitional orientations of the mobile device 102 with the transitional orientation dataset 118 to confirm that the mobile device 102 is changing orientations that would place the mobile device 102 into an orientation approximated by the second baseline dataset 120, the third baseline dataset 122, or another dataset.
Should the transitional orientations of the mobile device 102 deviate from the orientations approximated by the transitional orientation dataset 118, the processor 124 may determine that the user is not moving the mobile device 102 through a natural motion gesture for placing the mobile device 102 in the augmented reality display mode or the reading display mode. However, should the transitional orientations of the mobile device 102 approximate the orientations represented by the transitional orientation dataset 118, the mobile device 102 may then determine whether the mobile device 102 should be placed in the augmented reality display mode or the reading display mode. The processor 124 may determine whether to place the mobile device 102 in the augmented reality display mode or the reading mode by first detecting that the mobile device 102 is no longer moving, such as by analyzing the data output by the accelerometer 106, and then comparing the resting orientation of the mobile device 102 with the orientation represented by the second baseline dataset 120 (e.g., the orientation for activating the augmented reality display mode) and/or comparing the resting orientation of the mobile device 102 with the orientation represented by the third baseline dataset 122 (e.g., the orientation for activating the reading display mode).
In another implementation, the processor 124 evaluates the transitional timing dataset 202 to determine whether to place the mobile device 102 in the augmented reality display mode, the reading display mode, another defined mode, or no mode at all. In this alternative implementation, after recognizing that the mobile device 102 is in the voice input mode and that the orientation of the mobile device 102 approximates the orientation represented by the first baseline dataset 116, the processor 124 may initialize and maintain a timer for determining when the processor 124 should next determine the orientation of the mobile device 102.
As previously discussed with reference to
In yet a further implementation, the processor 124 may forego referring to the transitional orientation dataset 118 or the transitional timing dataset. For example, when the processor 124 determines that the mobile device is in the voice input mode and that the mobile device 102 has received voice input via the input interface 110, the processor 124 may begin polling the magnetic sensor 104 and the accelerometer 106 to determine if the mobile device 102 is placed into an orientation for the augmented reality display mode or the reading display mode. In this alternative implementation, the processor 124 may rely on orientation thresholds to determine that whether the mobile device 102 is moving, such as by comparing the orientation thresholds with the output from the magnetic sensor 104, the accelerometer 106, or other component, while the mobile device 102 is moving or changing orientations. When the outputs from the magnetic sensor 104, the accelerometer 106, or both, indicate that the mobile device 102 is sufficiently stable (e.g., not moving), the processor 124 may then compare the resting orientation of the mobile device 102 with the orientations represented by the second baseline dataset 120 and the third baseline dataset 122. Based on comparing the resting orientation with the orientations represented by the second baseline dataset 120 and the third baseline dataset 122, the processor 124 may place the mobile device 102 in the augmented reality display mode, the reading display mode, another mode, or no mode at all.
After providing the voice input to the mobile device 102, the user 302 may change the operational mode of the mobile device 102 through a natural motion gesture that places the mobile device 102 into a previously configured or calibrated orientation.
Turning next to
While the processor 124 is detecting the orientation of the mobile device 102, the mobile device 102 may be in an input receiving mode such that the input interface 110 may be receiving an input from the user at block 410. In one implementation, the input received from the user is a voice input. However, it is possible that the input interface 110 may receive the voice input from the user before or after the processor 124 detects the orientation of the mobile device 102. Although the user may provide a voice input to the input interface 110 when the mobile device 102 is in the input receiving mode, the user may also provide other types of input, such as a tactile input when the user touches the display 112 of the mobile device 102, a textual input when the user uses a keyboard of the mobile device 102, or a combination of inputs.
Upon receiving the input, the input interface 110 may transmit the input to the processor 124 for use with the mobile application. As an example of an input that the user may provide to the mobile application is the name of a business, or the type of business, that the user desires to visit. Another example of an input that the user may provide is a subject matter input, such as where the user is searching for a particular thing, such as a particular shoe model, or a general thing, such as shoes in general. Yet a further example of an input that the user may provide is a mailing address, a specific location, such as a city name, or a generalized location, such as a region. Other types or combinations of inputs are also possible.
After receiving the input from the user, the processor 124 may prepare the output of the mobile application at block 414. An example of an output prepared by the mobile application is a set of businesses matching a business name, a business name matching an address, or a business name matching a subject matter, such as a shoe seller matching a search for the subject matter of shoes. Other types of output are also possible depending on the mobile application and the input provided by the user. The output from the mobile application may be buffered by the processor 124 or stored in the memory storage device 114 until the processor 124 has determined whether the mobile device 102 should be placed in a second or third operating mode. Alternatively, the processor 124 may transmit the output from the mobile application to the display 112 for viewing and review by the user.
After detecting the orientation of the mobile device 102, the processor 124 may compare the detected orientation with the first baseline dataset 116, which, in one implementation, may represent an orientation of the mobile device 102 for operating in a voice input operating mode. This is shown at block 412. By comparing the orientation of the mobile device 102 with the first baseline dataset 116, the processor 124 may be operative to determine whether the mobile device 102 should be placed in the first operating mode or whether the mobile device 102 is operating in the first operating mode. In block 416, the processor 124 may then make a determination whether the orientation of the mobile device 102 approximates the orientation represented by the first baseline dataset 116. As discussed previously with regard to
Although
The processor 124 may then determine whether the transitional condition has been satisfied at block 504. In one implementation, the transitional condition may be satisfied where the processor 124 determines that the transitional orientation of the mobile device 102 approximate the transitional orientations represented by the transitional orientation dataset 118. In another implementation, the transitional condition may be satisfied when the processor 124 determines that the time period represented by the transitional timing dataset 202 has elapsed. In yet another implementation, and depending on the setup of one or more orientation thresholds, the transitional condition may be satisfied when orientation data meets, exceeds, or falls below or one or more orientation thresholds.
After the transitional condition is satisfied, the processor 124 may then detect the orientation of the mobile device 102 at block 506, and then determine whether the detected orientation of the mobile device 102 approximates the orientations represented by the second baseline dataset 120, the third baseline dataset 122, another baseline dataset, or does not approximate any one of these orientations at block 508.
Depending on the orientation detected by the processor 124, the processor 124 may change the operating mode of the mobile device 102. Where the detected orientation of the mobile device 102 approximates the orientation represented by the second baseline dataset 120, the processor 124 may change the operating mode of the mobile device 102 from the first operating mode, such as the voice input mode, to the second operating mode, such as the augmented reality display mode as shown at block 510. Where the detected orientation of the mobile device 102 approximates the orientation represented by the third baseline dataset 122, the processor 124 may change the operating mode of the mobile device 102 from the first operating mode, such as the voice input mode, to the third operating mode, such as the reading display mode as shown at block 512. Moreover, should the orientation detected by the processor 124 not approximate one or more of the orientations represented by any of the baseline datasets, the processor 124 may change the operating mode of the mobile device 102 from the first operating mode to a default operating mode or processor 124 may not change the operating mode of the mobile device 102 as shown at block 518.
When the processor 124 changes the operating mode of the mobile device 102 from the voice input mode to the augmented reality display mode, the processor 124 may display one or more augmented reality images on the display 112 of the mobile device 102 as shown at block 514. Placing the mobile device 102 in the augmented reality display mode may also include activating one or more components of the mobile device 102, such as the camera 108 for recording images for display on the display 112 of the mobile device 102. As mentioned above, when the mobile device 102 is operating in the augmented reality display mode, the images recorded by the camera 108 may be overlaid with one or more computer-generated graphic elements, such as labels, icons, software buttons, two-dimensional or three-dimensional computer-generated images, or any other type of computer-generated graphic elements. The computer-generated graphic elements may be distinguished from the images recorded by the camera 108 because the computer-generated graphic elements may not be physically present in the environment in which the mobile device 102 operates.
Moreover, one or more of the computer-generated graphic elements may correspond to the results output by the mobile application based on the voice input previously provided by the user. For example, when a user searches for a business and provides the mobile application with the address of the business, the augmented reality display mode may include displaying the building of the business recorded by the camera 108 on the display 112 along with a computer-generated outline overlaid on the building to distinguish this building from other buildings in the environment. In another example, when a user requests directions to a particular location from the mobile application, the augmented reality display mode may include displaying a road on which the user is standing recorded by the camera 108 overlaid with a computer-generated arrow pointing in the direction that the user should travel to reach the requested location. By overlaying the images recorded by the camera 108 with computer-generated elements that correspond to one or more results output by the mobile application, a user may gain a better understanding of the results of the mobile application as they relate to the user's environment.
When the processor 124 changes the operating mode of the mobile device 102 from the voice input mode to the reading display mode, the processor 124 may display the results output from the mobile application on the display 112 of the mobile device 102 in a preselected format at block 514. The preselected format may include a list format, an outline format, a graphical format, a combination of these formats, or any other type of format. The user or the processor 124 may calibrate the reading display mode such that the results displayed in the reading display mode are legible when viewed in the environment in which the mobile device 102 is operating. An example of calibrating the reading display mode is adjusting the contrast or brightness of the display 112 of the mobile device 112. Another example of calibrating the reading display mode is selecting a font for displaying the words of the results output by the mobile application. Other examples of calibrating the reading display mode are also possible. In other words, the reading display mode is an operating mode of the mobile device 102 that facilitates easily and legibly conveying the results of the mobile application to the user.
