TECHNICAL FILED

[00021 Embodiments described herein generally relate to user interfaces and in particular, to text selection functions for various types of processing and display in augmented reality.

BACKGROUND

[0003] Augmented reality (AR) viewing may be defined as a live view of a real-world environment whose elements are supplemented (e.g., augmented) by computer-generated sensory input such as sound, video, graphics, or GPS data. For example, software applications executed by smartphones may use the smartphone's imaging sensor to capture a real-time event being experienced by a user while overlaying text or graphics on the smartphone display that supplement the real-time event.

[0004] A head-mounted display (HMD), also sometimes referred to as a helmet-mounted display, is a device worn on the head or as part of a helmet that is able to project images in front of one or both eyes. An HMD may be used for various applications including augmented reality or virtual reality simulations. HMDs are used in a variety of fields such as military, gaming, sporting, engineering, and training.

DETAILED DESCRIPTION

[0017] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of some example embodiments. It will be evident, however, to one skilled in the art that the present disclosure may be practiced without these specific details.

[0018] Systems and methods described herein implement text functions in augmented reality. Example functions include a look-up (definition), translation (from one language to another), or other processing that may be appropriate for textual content. While augmented reality (AR) may be used with handheld devices, head-mounted displays (HMD), or other computing platforms, many of the embodiments described herein refer to AR in HMDs. HMDs come in a variety of form factors including goggles, visors, glasses, helmets with face shields, and the like. As technology improves, HMDs are becoming more affordable for consumer devices and smaller and lighter to accommodate various applications,

[0019] FIG. 1 is a diagram illustrating an environment 100 where users are interacting with the environment 100 through AR, according to an embodiment. The environment 100 includes an event (e.g., an animal displayed in a cage) that is being viewed by a plurality of users 102, 104, and 106. One or more of the users 102-106 may have an AR subsystem. The users 102-106 may use different types of AR subsystems. For example, one of the users 106 is shown with a wearable electronic device 108 (e.g., AR eyeglasses, goggles, etc.) that may include or be the AR subsystem that provides AR content to user 106. Another two of the users 102, 104 are shown with handheld electronic devices (e.g., smartphones, tablets, etc.) that may include or be the AR subsystem that provides AR content to those users 102, 104. The present embodiments are not limited to any one type of AR subsystem.

[0020] In FIG. 1 , the users 102, 104, 106 are viewing the event. The three users 102, 104, 106 who are viewing the event may be using their AR

subsystems to supplement the event with AR content. A sign 110 includes text. The users 102, 104, 106 may initiate a text function on the sign's text, in various embodiments.

[0021 ] Text functions include, but are not limited to translating the text, copying the text (e.g., for use in another application), enlarging the text, looking up definitions, providing additional information about the content, and the like. The text function may be performed and a result of the function rendered in the AR content. Alternatively, the text function may be performed and an indication that the function was performed may be provided to the user.

[0022] To initiate a text function in AR, the user performs a specific gesture. Gestures may be user-defined and configured. For example, a "double-pointing" motion may indicate to begin translation services. As another example, a single hand motion with two fingers pointing at the object with text may indicate to begin a copy text function. After copying text, the user may access another application in AR, such as an Internet browser, and paste the text into a user interface text control. Other types of gestures may be used. [0023] FIG. 2 is an HMD 200, according to an embodiment. The HMD 200 includes a see-though display surface 202, a camera array 204, and processing circuitry (not shown). An image or multiple images may be projected onto the display surface 202, such as by a mi crodi splay. Alternatively, some or ail of the display surface 202 may be an active display (e.g., an organic light-emitting diode (OLED)) able to produce an image in front of the user. The display also may be provided using retinal projection of various types of light, using a range of mechanisms, including (but not limited to) waveguides, scanning raster, color- separation and other mechanisms.

[0024 j The camera array 204 may include one or more cameras able to capture visible light, infrared, or the like, and may be used as 2D or 3D cameras (e.g., depth camera). The camera array 204 may be configured to detect a gesture made by the user (wearer) and the processing circuitry may use the gesture to capture images of text identified by the gesture, process the images (e.g., with optical character recognition), and render an image on the display surface 202 for the user,

[0025] FIG. 3 is another HMD 300, according to embodiment. The HMD 300 in FIG. 3 is in the form of eyeglasses. Similar to the HMD 200 of FIG. 2, HMD 300 includes two display surfaces 302 and a camera array 304. Processing circuitry (not shown) may perform the text functions described above.

[0026] FIGS. 4A and 4B illustrate text translation, according to an

embodiment. After a user performs a triggering gesture to enter a particular text function mode of the AR subsystem, the user may then perform one or more text functions on objects in the user's field of view. In the example illustrated in FIG. 4A, the AR subsystem is an HMD and the user is viewing the sign 110 of FIG. 1 , The user may be a German tourist visiting a zoo in the United States. After initiating a text translation mode of the AR subsystem, such as with a specific gesture, vocal command, or other input, the user points to the beginning of a text block to translate (point 400) and slides their finger over or near the text to translate, as illustrated in FIG. 4B, ending at point 402. In doing so, the AR subsystem provides a visual overlay on or near the real object (sign 110) of the translated text 404. In a related example, the text on the real-world object is highlighted using a translucent overlay. This is useful to the user to indicate which text is being operated upon. The highlighting may be in a distinctive color, such as yellow, and appear as though a highlighter marker was used to color the real -world object. Alternatively, the highlighting may be a colored block with or without texture, gradient, patterns, or other embellishments, encompassing the textual content. It is understood that other operations may be performed based on the indication or selection gesture performed (e.g., point and slide in this example).

[0027] FIGS. 5A and 5B illustrate a selection gesture, according to an embodiment. In this example, the user begins pointing at a first point 500 and then moves their hand to a second point 502, the points 500, 502 are used to create a virtual selection box 504. The contents of the selection box 504 (e.g., sign 1 10) are then operated upon. In the example illustrated in FIG. 5B, after the user has completed their selection gesture, an option dialog box 506 is displayed in the AR content and the user may select the operation to perform on the selected AR content (e.g., the sign 1 10). A default operation may be performed as designated by user preferences or system design.

[0028] FIGS, 6 A and 6B illustrate another selection gesture, according to an embodiment. In this example, the selection gesture begins at a first point 600 and ends at approximately the same position, at the second point 602. The gesture creates a substantially circular or elliptical shape, which defines the selection area 604. The example illustrated in FIG. 6B shows that the AR content 606

(e.g., the translated text) may be displayed adjacent to the real-world object (e.g., the sign 1 10). A default operation or user-selected operation may then be performed on the selected AR content.

[0029] FIG. 7 is a schematic drawing illustrating an AR subsystem 700 in the form of a head-mounted display, according to an embodiment. The AR subsystem 700 includes a visual dispiay unit 702, an acceierometer 704, a gyroscope 706, a gaze detection unit 708, a world-facing camera array 710, and a gesture detection unit 712.

[0030] The visual display unit 702 is operable to present a displayed image to the wearer (e.g., user) of the AR subsystem 700. The visual display unit 702 may operate in any manner including projecting images onto a translucent surface between the user's eye(s) and the outer world, the translucent surface may implement mirrors, lenses, prisms, color filters, or other optical apparatus to generate an image. The visual display unit 702 may operate by projecting images directly onto the user's retinas. In general, the visual display unit 702 operates to provide an augmented reality (AR) experience where the user is able to view most of the real world around her with the computer generated image (CGI) (e.g., AR content) being a relatively small portion of the user's field of view. The mixture of the virtual reality images and the real-world experience provides an immersive, mobile, and flexible experience.

[0031] Alternatively, in some form factors, the visual display unit 702 may provide an AR experience on a handheld or mobile device's display screen. For example, the visual display unit 702 may be a light-emitting diode (LED) screen, organic LED screen, liquid crystal display (LCD) screen, or the like,

incorporated into a tablet computer, smartphone, or other mobile device. When a user holds the mobile device in a certain fashion, a world-facing camera array on the backside of the mobile device may operate to capture the environment, which may be displayed on the screen. Additional information (e.g., AR content) may be presented next to representations of real-world objects. The AR content may be overlaid on top of the real-world object, obscuring the real-world object in the presentation on the visual display unit 702. Alternatively, the presentation of the AR content may be on a sidebar, in a margin, in a popup window, in a separate screen, or the like.

[0032] The AR subsystem 700 includes an inertial tracking system that employs a sensitive inertial measurement unit (IMU). The IMU may include the accelerometer 704 and the gyroscope 706, and optionally includes a

magnetometer. The IMU is an electronic device that measures a specific force, angular rate, and sometimes magnetic field around the AR subsystem 700. The IMU may calculate six degrees of freedom allowing the AR subsystem 700 to align AR content to the physical world or to generally determine the position or movement of the user's head.

[0033] The gaze detection unit 708 may employ an eye tracker to measure the point of gaze, allowing the AR subsystem 700 to determine where the user is looking. Gaze detection may be performed using a non-contact, optical method to determine eye motion. Infrared light may be reflected from the user's eye and sensed by an inward-facing video camera or some other optical sensor. The information is then analyzed to extract eye rotation based on the changes in the reflections from the user's retina. Another implementation may use video to track eye movement by analyzing a corneal reflection (e.g., the first Purkinje image) and the center of the pupil. Use of multiple Purkinje reflections may be used as a more sensitive eye tracking method. Other tracking methods may also be used, such as tracking retinal blood vessels, infrared tracking, or near-infrared tracking techniques. The gaze detection unit 708 may calibrate the user's eye positions before actual use.

[0034] The world-facing camera array 710 may include one or more infrared or visible light cameras, able to focus at long-range or short-range with narrow or large fields of view. The world-facing camera array 710 may include gimbals or other mechanical or electromechanical mechanisms to automatically level the cameras while the AR subsystem 700 is moving. For example, the AR subsystem 700 may include a recessed pocket in which a camera is housed on a gimbai. When the wearer looks up or down, the gimbaled camera may automatically level itself so as to maintain a relatively level field of view. In addition, cameras in the world-facing camera array 710 may include

electromotors to pan the camera from left to right or tilt the camera from up to down. Pan and tilt controls may be used to maintain a relatively level field of view. Gimbals and electromotors may be used in combination to stabilize the field of view when the AR subsystem 700 is moving. In addition to, or alternatively, cameras in the world-facing camera array 710 may include image processing features to stabilize the image using specialized hardware or software. Thus, any form or image stabilization including, but not limited to optical image stabilization (OIS), sensor-shift or mechanical stabilization, or digital image stabilization may be used alone or in combination to stabilize the images captured by the world-facing camera array 710.

[0035] In operation, while the user is wearing the AR subsystem 700, the user may perform a combination movements that combine into a gesture. The world- facing camera array 710 captures the movements and the gesture detection unit 712 determines whether the movements constitute a recognized gesture. If the movements do constitute a recognized gesture, the gesture detection unit may trigger operations performed by an image processing unit 714. The image processing unit 714 may interface with the camera array 7 0 to obtain one or more images of the environment around the user. The image processing unit 71 may perform various operations including identifying a selection area of the iniage(s), performing optical character recognition on the selection area, interfacing with a language translation unit 716 in some cases, and interfacing with the visual display unit 702 to provide AR content to display.

[0036] FIG. 8 is a flowchart illustrating control and data flow, according to an embodiment. A trigger event is detected (operation 800). The trigger event may be a specific gesture, a vocal command, pressing a hard button, or the like. The trigger event is used to place the AR subsystem in gesture recognition mode for text operations. Gesture recognition mode may be active for a short time (e.g., 30 seconds) or for a longer time (e.g., until deactivated).

[0037] Once in gesture recognition mode, a selection gesture is recognized (operation 802). The selection gesture may be any of a number of gestures using one or two hands, one or more fingers, etc. The selection gesture may be a point- and-swipe gesture, a looping elliptical gesture, spreading hands or fingers to define a selection area, using gestures to define a first and second point which may then be used to define two opposite corner points in a rectangular selection area, or the like. A selected area is identified (operation 804) based at least in part on the selection gesture.

[0038] Based on the selection area defined by the selection gesture, a text operation is performed (operation 806). The text operation performed may be controlled by a user input or by user preferences (item 808). For example, the user may select the operation from a popup dialog box that appears in the AR content or verbalize their selection with a voice command. Alternatively, the user may set preferences to always perform translation unless overridden.

[0039] An acceierometer 810 and a gyroscope 812 are used to detect head movement (operation 814). AR content is rendered (operation 816) and may be oriented based on the head movement detected at 814 to maintain a consistent visual cohesiveness between AR content and the real world. The AR content is presented to the user at operation 818. The presentation may be in a FTMD, on a smartphone, or by other display modalities.

[0040] In some embodiments, one or more eye gaze detection cameras 820 are used to detect the user's eye gaze (operation 822). The user's eye gaze may be used to validate the object being selected by the selection gesture (operation 804). [0041] FIG. 9 is a block diagram illustrating system 900 for implementing text functions in augmented reality, according to an embodiment. The system 900 may include a display 902, a gesture detection module 904, a camera array 906, a text module 908, a presentation module 910, and an optional trigger detection module 912.

[0042] The display 902 may be any mechanism to provide a visual presentation to a user of the system 900 as described above with respect to visual display unit 702. The display 902 may be configured to display a field of view to a user of the system. When the display 902 is used in a ITMD, the display 902 may be translucent or transparent to allow the user to view the real world through the display 902, except for any portions where an image or other visual representation is presented on the display 902. When the display 902 is in a mobile device, such as a tablet or smartphone, the display 902 may be a LCD, LED, or OLED panel, for example.

[0043] The gesture detection module 904 may be configured to detect a selection gesture performed by a user of the system, the selection gesture defining a selection area in the field of view.

[0044] In an embodiment, to detect the selection gesture, the gesture detection module 904 is to access image data of an arm, finger, or hand motion of the user captured by the camera array 906 and identify the selection gesture based on the image data. The image data may be a number of successive images (e.g., video) over which the gesture is performed.

[0045] In an embodiment, to detect the selection gesture, the gesture detection module 904 is to access depth image data of an arm, finger, or hand motion of the user captured by the camera array 906 and identify the selection gesture based on the depth image data. The depth image data may be a number of successive images (e.g., video) over which the gesture is performed.

[0046] In an embodiment, to detect the selection gesture, the gesture detection module 904 is to access motion data from an auxiliary device, the motion data describing an arm, finger, or hand motion of the user and identify the selection gesture based on the motion data. In a further embodiment, the auxiliary device comprises a wearable device. The wearable device may be any type of wearable device that is able to convey motion data indicative of a finger, hand, or arm gesture on one or both arras of a user. In various embodiments, the wearable device comprises a smartwatch or a smart ring.

[0047] In an embodiment, the selection gesture comprises a point-and-swipe motion, and the selection area comprises a linear character string. A point-and- swipe motion is one where the user initially makes an affirmative pointing motion followed by a sweep of their finger, hand, or arm. An affirmative pointing motion is one where the user motions with their wrist, hand, and finger, as if shaking water off of their fingers. The affirmative pointing motion may be detected by a motion that exceeds a threshold motion based on a threshold distance moved, a threshold acceleration observed in the motion, or

combinations thereof. The point-and-swipe motion may indicate a line of text, a single word, or some other linear arrangement of text to operate upon.

Alternatively, the point-and-swipe motion may define a block of text, such as that shown in the example illustrated in FIGS. 4A-4B.

[0048] In an embodiment, the selection gesture comprises a point-swipe-point motion, and the selection area comprises a rectangular area including a character block. The point-swipe-point motion may include a first affirmative pointing motion, followed by a sweeping or swipe motion, and terminating with a second affirmative pointing motion. The point-swipe-point motion is illustrated as an example in FIGS. 5A-5B.

[0049] In an embodiment, the selection gesture comprises a point-and-loop motion, and the selection area comprises a character block. The point-and-loop motion may include an affirmative pointing motion followed by a sweeping motion that generally describes a circle or ellipse in space. The sweeping motion terminates near the location of the affirmative pointing motion, thus completing the loop. An example of the point-and-loop motion is illustrated in FIGS. 6A and 6B. Both the point-swipe-point and the point-and-loop gestures may be used to define a single word, a line of text, or a block of text, in various embodiments.

[0050] The cam era array 906 may be confi gured to capture an image of the selection area. The camera array 906 may include one or more cameras able to capture visible light, infrared, or the like, and may be used as 2D or 3D cameras (e.g., depth camera). The camera array 906 may configured like camera array 204 or camera array 710, in various embodiments. [0051] The text module 908 may be configured to perform a text operation on text identified in the image. The presentation module 910 may be configured to present an indication of the text operation to the user.

[0052] In an embodiment, to perform the text operation, the text module 908 is to identify a character string from the text identified in the image and translate the word from a first language to a second language. The character string may be a word, a sentence, or a paragraph, in various embodiments. In an embodiment, to present the indication of the text operation, the presentation module 910 is to display a translation of text identified in the image in the field of view and collocated with the text identified in the image. Text translation may use one or more dictionaries or other repositories to determine a translation or replacement phrase for the text in the image. The translation may be a direct translation or may account for accents, dialects, or local slang. The replacement text or translation used may be configurable by the user. Collocated in this disclosure means near to or overlaid upon the text identified in the image. The collocated translated text or replacement text may be produced as an image that fully obscures the real-world object, or only partially obscures it (e.g., with a translucency).

[0053] In an embodiment, to perform the text operation, the text module 908 is to identify a portion from the text identified in the image and copy the portion from the text identified in the image to a memory buffer, the memory buffer used for copy and paste operations. In such an embodiment, to present the indication of the text operation, the presentation module 910 is to display a notification in the field of view. In a further embodiment, the notification comprises an icon. As such, the user may see text and is able to capture and paste the text to another application. For example, the user may observe a recipe that is interesting, and capture and paste the text of the recipe to a data repository, such as a virtual notepad, for later access and use. As another example, the user may see a hyperlink to a business printed on the side of a business vehicle, gesture to select the hyperlink, open an Internet browser, and paste the hyperlink into an address field of the browser to navigate to the website. Other types of copy-paste operations are understood to be within the scope of this disclosure.

[0054] In an embodiment, to perform the text operation, the text module 908 is to identify a portion from the text identified in the image and copy the portion from the text identified in the image to a memory buffer, the memory buffer used for copy and paste operations. In such an embodiment, to present the indication of the text operation, the presentation module 910 is to produce an audible notification to the user. For example, when the text copy operation is successful, a high pitch tone is played to the user, and when the text copy operation is unsuccessful, a low pitch buzz is played to the user. Alternatively, a voice may be used to provide the user a "Copy Successful" phrase or a "Copy Failed" phrase, according to the result of the operation. Thus, in an embodiment, the audible notification comprises a voice notification. In another embodiment, the audible notification comprises a tonal notification.

[0055] In some embodiments, a trigger event is first detected before the selection gesture is detected. In other embodiments, the system 900 continually observes the user's motions to determine whether a selection gesture occurred. Using a trigger event may conserve computing and battery power. Thus, in an embodiment, the trigger detection module is to detect, at the system 900, a trigger action, the trigger action to initiate a selection gesture detection mode to detect the selection gesture and capture the selection area. The trigger action may be various types of actions performed by the user, such as pressing a button on the system (e.g., a hard button on the outside of the housing of the system), performing a specific gesture, using a voice command, using a tapping haptic- based trigger, sliding a physical switch, or the like. In an embodiment, to detect the trigger action, the trigger detection module 912 is to detect a trigger gesture performed by the user. Detecting the trigger gesture may be performed similarly to detecting the selection gesture.

[0056] Thus, in an embodiment, to detect the trigger gesture, the trigger detection module 912 is to access image data of an arm, finger, or hand motion of the user and identify the trigger gesture based on the image data. In another embodiment, to detect the trigger gesture, the trigger detection module 912 is to access depth image data of an arm, fi nger, or hand motion of the user and identify the trigger gesture based on the depth image data. In another

embodiment, to detect the trigger gesture, the trigger detection module 912 is to access motion data from an auxiliary device, the motion data describing an arm, finger, or hand motion of the user and identify the trigger gesture based on the motion data. [0057] In an embodiment, the field of view is defined without use of eye gaze tracking information. Thus, the user is able to select the word, line, or block of text without actively gazing at the text. Further, many systems that implement eye gaze tracking use an inward or user-facing camera. As such, systems that do not use eye gaze tracking for text operations, such as those described herein, may have design, functional, and economical advantages over systems that include eye gaze tracking abilities.

[0058] FIG. 10 is a flowchart illustrating a method 000 of implementing text functions in augmented reality, according to an embodiment. At block 1002, a selection gesture performed by a user of a user device is detected at the user device, the user device displaying a field of view to a user of the user device, and the selection gesture defining a selection area in the field of view. In an embodiment, the selection gesture comprises a point-and-swipe motion, and the selection area comprises a linear character string. In another embodiment, the selection gesture comprises a point-swipe-point motion, and the selection area comprises a rectangular area including a character block. In another

embodiment, the selection gesture comprises a point-and-loop motion, and the selection area comprises a character block.

[0059] In an embodiment, detecting the selection gesture comprises capturing image data of an arm, fi nger, or hand motion of the user and identifying the selection gesture based on the image data.

[0060] In an embodiment, detecting the selection gesture comprises capturing depth image data of an arm, finger, or hand motion of the user and identifying the selection gesture based on the depth image data.

[0061] In an embodiment, detecting the selection gesture comprises receiving motion data from an auxiliary device, the motion data describing an arm, finger, or hand motion of the user and identifying the selection gesture based on the motion data.

[0062] At block 1004, an image of the selection area is captured.

[0063] At block 1006, a text operation is performed on text identified in the image.

[0064] At block 008, an indication of the text operation is presented via the user device, to the user. [0065] In an embodiment, performing the text operation comprises identifying a character string from the text identified in the image and translating the word from a first language to a second language. In such an embodiment, herein presenting the indication of the text operation comprises displaying a translation of text identified in the image in the field of view and collocated with the text identified in the image. In various embodiments, the character string is a word, a sentence, or a paragraph.

[0066] In an embodiment, performing the text operation comprises identifying a portion from the text identified in the image and copying the portion from the text identified in the image to a memory buffer, the memory buffer used for copy and paste operations. In such an embodiment, presenting the indication of the text operation comprises displaying a notification in the field of view. In a further embodiment the notification comprises an icon.

[0067] In an embodiment, performing the text operation comprises identifying a portion from the text identified in the image and copying the portion from the text identified in the image to a memory buffer, the memor buffer used for copy and paste operations. In such an embodiment, presenting the indication of the text operation comprises producing an audible notification to the user. In an embodiment, the audible notification comprises a voice notification. In another embodiment, the audible notification comprises a tonal notification. Combinations of voice and tone may be used.

[0068] In an embodiment, the method 1000 includes detecting, at the user device, a trigger action, the trigger action to initiate a selection gesture detection mode to detect the selection gesture and capture the selection area.
