Examples generally relate to gesture recognition and more specifically to gesture recognition and interaction using a wearable device.
Augmented reality (AR) includes a presentation of a real world image or image stream that is augmented (e.g., modified, altered, or amended) with a sensory output such as a sound or visual augmentation. Augmenting image data is generally done in real-time. In general, AR supplants a real world view that is captured, processed, and output to provide a simulated view. AR has many applications including gaming, maintenance, entertainment, directions, and guidance, among others.
In the drawings, which are not necessarily drawn to scale, like numerals may describe similar components in different views. Like numerals having different letter suffixes may represent different instances of similar components. The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed herein.
Discussed generally herein are systems, devices, and methods for AR and associated AR user interactions. Embodiments discussed herein may be implemented using a wearable display, such as a head-wearable display, or in connection with other AR-capable computing device (e.g., mobile computing devices, such as smartphones).
As described herein, various mechanisms of AR user interactions may be provided through the use of an AR device having a camera and a display. One way of interacting with a body-mounted camera is for a wearable device to use machine-vision to detect a user's finger or hand gesture that may be interpreted as a command. A gesture (e.g., air gesture) in front of a wearable camera combined with object recognition may provide a variety of usage models and applicability to AR applications.
The wearable device generally includes an image (e.g., video) capturing mechanism, such as a camera, and an output device to display a captured image to a user. The image capture device may be mounted so that the user wearing the image capture device may perform a gesture between a lens of the image capture device and an object that is a subject of the gesture. The gesture and the object may be recognized by the device. The gesture may cause the device to augment image data captured by the camera based on a variety of data, such as the gesture, object, a social context, a spoken sound, a gesture-selected operation, or a combination thereof, among others.
Reference will now be made to the FIGS. to further describe details of systems, apparatuses, and methods for AR.
The camera module 102 may translate a scene in a field of view of the camera module 102 into image data (e.g., video, still, or other image data). The camera module 102 may include a digital camera, video camera, camera phone, or other image capturing device.
The object recognition module 104 may detect or recognize (e.g., detect and identify) an object in the image data. The object recognition module 104 may delineate (e.g., extract) an object from the image data, such as to isolate the object from the surrounding environment in the field of view of the camera module 102 or in the image data. The object recognition module 104 may use at least one of an appearance-based method or feature-based method, among other methods, to detect, recognize, or delineate an object.
The appearance-based method may include generally comparing a representation of an object to the image data to determine if the object is present in the image. Examples of appearance-based object detection methods include an edge matching, gradient matching, color (e.g., greyscale) matching, “divide-and-conquer”, a histogram of image point relations, a model base method, or a combination thereof, among others. The edge matching method may include an edge detection method that includes a comparison to templates of edges of known objects. The color matching method may include comparing pixel data of an object from image data to previously determined pixel data of reference objects. The gradient matching method may include comparing an image data gradient to a reference image data gradient. The “divide-and-conquer” method may include comparing known object data to the image data. The histogram of image point relations may include comparing relations of image points in a reference image of an object to the image data captured. The model base method may include comparing a geometric model (e.g., eigenvalues, eigenvectors, or “eigenfaces”, among other geometric descriptors) of an object, such as may be stored in a model database, to the image data. These methods may be combined, such as to provide a more robust object detection method.
The feature-based method may include generally comparing a representation of a feature of an object to the image data to determine if the feature is present, and inferring that the object is present in the image data if the feature is present. Examples of features of objects include a surface feature, corner, or edge shape. The feature-based method may include a Speeded Up Robust Feature (SURF), a Scale-Invariant Feature Transform (SIFT), a geometric hashing, an invariance, a pose clustering or consistency, a hypothesis and test, an interpretation tree, or a combination thereof, among other methods.
Delineating an object may include determining an outline or silhouette of an object and determining image data (e.g., pixel values) within the outline or silhouette. The determined image data or pixel values may be displayed or provided without displaying or providing the remaining image data of the image the object was delineated from. The delineated object may be displayed over a still image or otherwise displayed using the output module 110. A user may cause one or more operations to be performed on an object by performing a gesture or command while the still image is being displayed. More details regarding examples of these operations are discussed with regard to
The gesture recognition module 106 may identify a hand or finger in image data (e.g., image data corresponding to a single image or image data corresponding to a series of images or multiple images) and determine its motion or configuration to determine if a recognizable gesture has been performed. The gesture recognition module 106 may process gestures that are on-line or off-line. An on-line gesture is generally a direct manipulation gesture that is used to modify an object, whereas an offline gesture is a gesture that is processed after an interaction with an object (e.g., activating a menu screen).
The gesture recognition module 106 may use a three-dimensional or two-dimensional recognition method. Generally, a two-dimensional recognition method requires fewer computer resources to perform gesture recognition than a three-dimensional method. The gesture recognition module 106 may implement a skeletal-based method or an appearance-based method, among others. The skeletal-based method includes modeling a finger or hand as one or more segments and one or more angles between the segments. The appearance-based model includes using a template of a hand or finger and comparing the template to the image data to determine if a hand or finger substantially matching the template appears in the image data.
The image rendering module 108 may modify the image data, such as to augment the image data and provide an AR image. The image rendering module 108 may alter the image data based on data from the object recognition module 104, the gesture recognition module 106, a speech recognition module 112, a context module 116, or an authentication module 118.
The output module 110 may include a speaker, a radio (e.g., Bluetooth, cellular, or other radio) receiver, transmitter, or transceiver, a display, projector, or other device. The output module 110 can be operable to provide a view of an image captured by the camera module 102 or a view of an augmented image corresponding to augmented image data, such as may be provided by the image rendering module 108. The output module 110 may include a Liquid Crystal Display (LCD), a Light Emitting Diode (LED), a plasma display, a touch screen display, or a projector or screen, among others.
The speech recognition module 112 may interpret a sound (e.g., a word or phrase) captured by a microphone 114 and provide data indicative of the interpretation. The sound may be interpreted using a Hidden Markov Model (HMM) method or a neural network method, among others.
The context module 116 may determine a user's social circumstance and provide data indicative of the user's determined social circumstance. Examples of social circumstances may include a user exercising, conversing, driving, shopping, eating, watching a program (e.g., a movie, television, or other program), working, visiting a person, place, or thing, among others. The social circumstance of the user may be determined based on at least one of a location, speed, or direction of the user, one or more people or objects in the image data, a date or time of day, or an application state of an application running on the user's wearable device.
In one or more embodiments, if the location of the user is a coffee shop or other social situation, voice commands (e.g., the speech recognition module 112 or microphone 114) may be disabled. In one or more embodiments, if the user is traveling within a first range of speeds, the user may be determined to be walking or running. If another person's voice is consistently being picked up by the microphone, the user may be determined to be conversing with another person or listening to another person's voice. In one or more embodiments, a combination of a location and a person or object may indicate that a user is visiting a friend or family member.
The authentication module 118 may provide a security mechanism for the system 100. The authentication module 118 may include a policy that defines a set of one or more operations that are required to be performed for a user to access functionality of one or more modules of the system 100. An example of an authentication method and an example of the functionality provided by the authentication module 118 is discussed with regard to
The system 100 may include a wired or wireless connection to a network 120 (e.g., the internet or a cellular or WiFi network, among others). The network 120 may provide data that may be provided to a user, such as through the output module 110. For example, the network 120 may provide directions, data about an object in the image data, an answer to a question posed through the speech recognition module 112, an image (e.g., video or series of images) requested, or other data.
In one or more embodiments that include a radio, a user may perform a gesture (or voice command) that causes the radio to transmit a signal that calls another device. In one or more embodiments, a user may perform a gesture (or voice command) that causes the radio to transmit a signal that turns on a device that appears in the field of view of the camera. The device may be associated with an object (e.g., a person) recognized in image data.
In one or more embodiments, a gesture may cause different commands to be performed on image data based on a recognized object. For example, an underline gesture near a text object may cause the text to be underlined, and an underline gesture near another object may cause the object to be highlighted. In other examples a box gesture around an object may cause a framed or cropped image of the object to be displayed depending on the object and a point gesture to a distant recognized object may cause additional information regarding the recognized object like distance or navigation information to be displayed depending on the object.
In one or more embodiments, a user may name an object or face using their voice or a gesture. For example, the user may point to one of multiple people or objects and say a name. Subsequently, the face may be recognized with that name label and any associated data to that label. Contextual information (e.g., as determined by the context module 116) may help narrow the number of possible labels, both during training and during recognition. For example, items in a kitchen may be labeled while the user is cooking, but if the user goes to the refrigerator to get a drink or a snack, the labels may remain hidden from the user's view.
In one or more embodiments, the system 100 may apply a tag or other information that may be used to provide a suggestion or recommendation to the user. For example, a gestures or voice command may be used as a “context” tag to indicate which image data includes useful information for the user. For example, a user might point to an object (as in
In one or more embodiments, a user may perform a gesture proximate to an object (or speak a voice command) that causes the camera module 102 to begin recording or provide a live video feed focused on an object in the field of view of the camera module 102. The camera module 102 may auto-focus on the object so as to provide a clear(er) view of the object or a recorded video that may be accessed by the user. The user may stop the camera module 102 recording or live video feed with another gesture (e.g., the same gesture) or voice command.
In one or more embodiments, the object recognition module 104 may recognize multiple objects in a given scene and the user may perform a gesture recognized by the gesture recognition module 106 that causes the image rendering module 108 to perform an operation on one or more of the multiple recognized objects. In one or more embodiments, a device gesture (e.g., a head motion or other bodily motion that moves a wearable device, a touchscreen input, or other input), may be used in lieu of or in combination with one or more gestures to provide a command to the image rendering module 108 that causes the image rendering module 108 to perform an operation on the image data.
The input 202 may include microphone data, camera data, touch screen data, radio data, capacitive surface data, or other input. A user may touch a capacitive surface to issue a command to a module of the system 200, such as to make the system 200 store an image to a local memory or the network 120, or to make the system 200 perform an operation, as discussed herein.
The object recognition module 204 may be similar to the object recognition module 104, and may include the capability to perform the same operations as the objection recognition module 104 and vice versa. The gesture recognition module 206 may be similar to the gesture recognition module 106, such as to include the capability to perform the same operations as the gesture recognition module 106 and vice versa. The context module 216 may be similar to the context module 116, such as to include the capability to perform the same operations as the context module 116 and vice versa. The authentication module 218 may be similar to the authentication module 118, and may include the capability to perform the same operations as the authentication module 118 and vice versa. The image rendering module 208 may be similar to the image rendering module 108, and may include the capability to perform the same operations as the image rendering module 108 and vice versa.
The recognition coordination module 222 may receive data from and coordinate communication or task management between the object recognition module 206, gesture recognition module 206, context module 216, and authentication module 218. The recognition coordination module 222 may provide data to the image rendering module 208 and the AR module 224. The data may indicate an action to be performed by the AR module 224 or the image rendering module 208. The data may indicate to the image rendering module 208 or the AR module 224 what image data to modify or transmit to the wearable display 210.
The recognition coordination module 222 may provide a command associated with a recognized gesture, an authentication attempt, or a voice command to be executed (e.g., by the AR module 224 or the image rendering module 208) on a recognized object. The command may be dependent on one or more variables such as a user's social circumstance as determined by the context module 216, a recognized object, a recognized gesture, a recognized voice command, or a result of an authentication attempt as determined by the authentication module 218. For example, if a first gesture (or voice command) is recognized, and the gesture is performed proximate to (or the voice command targets) a first recognized object (e.g., from the viewpoint of a user viewing the wearable display 210 or the output module 110) a first command may be provided. If the same gesture (or voice command) is recognized, and the gesture is performed proximate (or the voice command targets) a second recognized object a second command, different from the first command may be provided. Thus, the command provided may be dependent on the recognized object.
In another example, if a first gesture (or voice command) is recognized, and the gesture is performed proximate (or the voice command targets) a first recognized object and the context module 216 determines the user is in a first social circumstance, a first command (or no command) may be provided. If the same gesture (or voice command) is recognized, the gesture is performed proximate (or targets) the same recognized object, and the context module 216 determines the user is in a second social circumstance different from the first social circumstance, a second command (or no command), different from the first command may be provided. Thus, the command executed may be dependent on the social circumstance as determined by the context module 216.
In yet another example, a gesture performed during an authentication process may cause the recognition coordination module 222 to provide a different command than if the gesture is performed outside of the authentication process.
The AR module 224 may create a model of image data that may be rendered by the image rendering module 208. The model created may be based on the command provided by the recognition coordination module 222, the object recognition module 204, the gesture recognition module 206, the speech recognition module 112, the context module 216, or the authentication module 218.
The image rendering module 208 may create image data to be presented on the wearable display 210. The image rendering module 208 may receive parameters defining an image or a portion of an image, such as a geometric shape, lighting, shading, viewpoint, location, size, or texture data, and produce image data including those parameters. The image rendering module 208 may provide un-augmented image data corresponding to an image captured by the input 202 or augmented image data corresponding to an image captured by the input 202 and augmented in accord with a model, such as may be provided by the AR module 224.
The wearable display 210 may include a device operable to provide a view of an image captured by the input 202 or provided by the image rendering module 208. The wearable display 210 may include a body mountable structure with a display or projector affixed or attached thereto. The wearable display 210 may be configured to be worn on the head, a shoulder, arm, wrist, or other part of a user that allows a user to wear the display and visualize the display simultaneously.
Note that the functionality discussed with regard to a specific module may be implemented by another module. For example, the functionality provided by the recognition coordination module 222 may be performed by the image rendering module 108 or the network 120. Similarly, the functionality provided by the augmented reality module 224 may be provided by the image rendering module 108 or the network 120. Other functionality discussed with regard to the modules of
The gesture may include the user 324 performing a sweeping motion (e.g., a continuous motion from a point in the field of view to another point in the field of view), configuring one or more fingers in a specific shape (e.g., a sign language letter, word, or phrase, among other shapes), increasing or decreasing a distance between two fingers, pointing with one or more fingers, performing a tapping motion with one or more fingers, or a combination thereof, among other gestures. Note that, as discussed, the gesture may be performed using a finger, hand, or object in the field of view of the camera.
In one or more embodiments, the recognized gesture, such as may be recognized using the gesture recognition module 106, may cause an operation to be performed on an object in the image data. Note that the object may be recognized (e.g., by the object recognition module 104) before or after the gesture is performed or recognized. In one or more embodiments, the recognized gesture may be performed in the field of view of the camera 302 not proximate to an object, such as to cause the image rendering module 108 or 208 to perform a different command, such as displaying a menu of options to the user (e.g., overlaid on image data from an image-capturing device). A gesture directed at an object (e.g., an object that highlighted or otherwise indicated as being selected) may cause an operation to be performed on a device or data representative of the object. For example, if a selected object includes a vehicle, such as a vehicle that is the user's vehicle or a vehicle that the user controls, and the user directs an appropriate gesture or voice command toward the vehicle, the vehicle may be started. This may be accomplished using a subsystem in the system 100 or 200 that may issue a command to the vehicle.
While the still image is being displayed, the input 202 may continue to capture image data. The object recognition module 204 may delineate a hand, finger, or object (e.g., an object being manipulated by the user) from the captured image data. The wearable display 210 may display the delineated hand, finger, or object over the still image. The image rendering module 208 may cause the wearable display 210 to display the delineated hand, finger, or object at a location on the image that is relative to the hand, finger, or object location in the field of view of the input 202. This may allow the user to manipulate the still image using gestures while viewing their hand, finger, or object overlaid on the still image.
The gesture recognition module 106 may continue to recognize gestures and provide data indicating a recognized gesture, such as to cause an operation to be performed on the still image. In the example of
The operations displayed in the control box 436 may include any operation that may be performed with respect to the object 432 using a gesture or voice command or additional operations that may be performed on an image representation of the object 432. For example, an operation that may be performed on the image representation of the object 432 may include shrinking, enlarging, altering a color, intensity, or contrast of a at least a portion of the pixels of the image representation of the object 432, naming the object 432, adding a note with respect to the object 432, setting an alert to have the system 100 or 200 indicate to the user when the object (e.g., or an object similar to the object 432) is in the field of view of the camera module 102, displaying information about the object 432, presenting a text box which the user may type in, among other operations.
In one or more embodiments, if the authentication process fails (e.g., a predetermined number of times), an alternative authentication process may provide a user an alternative method of gaining access to the functionality of the system 100 or 200. For example, a series of security questions may be posed to a user, which the user may answer using voice commands or by providing data indicating the answer to the security questions. The authentication module 218 may allow a user to access the functionality of the system 100 or 200 in response to the user answering the security questions as detailed in the policy.
In one or more embodiments, an operation that may be performed using gesture recognition may be performed or altered through a sound spoken by the user. For example, a user may perform a gesture and at or around the time the gesture is performed, the user may enunciate a sound. The enunciated sound may be associated with an object proximate the performed gesture, such as to cause the image rendering module 208 to associate the announced sound with the object and cause the sound (in text form) to be displayed proximate the object. In another example, an operation caused by a gesture being performed that causes the image rendering module 208 to add text near an object may also be caused to be performed by the user saying the name of the object. In one or more embodiments, a sound spoken at or around a time a user performs a gesture may indicate to the system 100 or 200 which object the gesture is directed at.
In the example of
In another example, a user has previously indicated to the system 100 or 200 that the object 802 is a “fire hydrant” and the object recognition module 204 causes the image rendering module 208 to label the fire hydrant as a “fire hydrant” whenever a fire hydrant is to be displayed on the wearable display 210. In such a case, where an object is associated with a word or phrase, a user may provide a verbal command to a module of the system 100 or 200 to perform an operation on the object. For example, the user may say “enlarge fire hydrant”. This phrase may be recognized by the speech recognition module 212, which may produce data that causes the image rendering module 208 to create an image including the object 802.
Another use case of the system 100 or 200 may include providing a medium through which a user may play a game, such as tag, scavenger hunt, laser tag, or other game.
The method 1000 may include extracting one or more fingers from other image data and providing data indicative of the extracted one or more fingers. The method 1000 may include displaying a still image including the detected object with the extracted one or more fingers overlaid on the still image. The operation at 1008 may augmenting the image data with a list of one or more user-selectable operations, which when selected by a user cause the selected operation to be performed on the image data. The operation at 1008 may include modifying the image data to include a plurality of targets and the operations further comprise determining whether the detected object touches one or more targets of the plurality of targets in a specified order, and in response to determining the detected object has touched the one or more targets in the specified order, providing data indicating a valid authentication procedure has been performed.
The operation at 1008 may include modifying the image data by performing a first operation in response to detecting a first object and modify the image data by performing a second, different operation in response to detecting a second, different object. The method 1000 may include associating a sound captured by a microphone with the recognized object by augmenting the image data with text representing the sound proximate to the detected object. The operation at 1008 may include determining a social circumstance of the user using at least one of a location, speed, or direction of the user, and one or more objects in the image data. The operation at 1008 may include modifying the image data by performing a first operation on the image data in response to determining the social circumstance is a first social circumstance and performing a second, different operation on the image data in response to determining the social circumstance is a second, different social circumstance.
AR, as discussed herein, may be performed in real time or near real time. Examples and embodiments, discussed herein demonstrate how the camera may capture the immediate environment and also capture a finger, hand, or object to be used a pointing device on an image of the immediate environment, such as in the same image frame(s).
One or more of the embodiments discussed herein may include an advantage over a prior AR or identification system, device, or method. For example on-the-fly training for recognizing new people is a difficult machine learning problem. However, using an embodiment discussed herein a user may gesture to a person or object in a camera frame and use voice input or another input method to associate a name with the face or object identified with the gesture. The analytical algorithms may then associate the name with the face or object to train a recognition model that may be used for various personal usages. Considering that there may be multiple strangers in a given camera frame this method may reduce the on-the-fly training complexity. For example, a user may set up a meeting with a person by saying “set up a meeting with xyz”. In another example, a user may use the system as a memory of past events, such as by asking “when did I last meet xyz?”. In another example, a contacts list may be populated using the names associated with the faces and voice commands. For example, a user may visit a person's house and say “X lives here”. The system may record the address associated with the location of the user in a contacts list under the name X. Other contact information for a person may enter through verbal commands.
Another advantage may include simplifying or enabling various objects and sub-activities in an activity recognition task that may be identified on-the-fly, enabling easier modelling of complex activities. For example, in a cooking activity a user may gesture toward various objects (pots/pans/spices etc.) and voice label them. This process may reduce the complexity of a cooking activity model builder. This model may then be used for recipe guidance as well as user activity tracking.
Another advantage may include providing more accurate or reliable recommendations to a user. By tagging objects as things of interest to the user the user may be capturing the content for later analysis. Different gestures with or without voice may be used as tags associated with the image data, so when subsequent analysis is done, these are recognized as objects or scenes of interest with some distinct meaning like “remember this”, “find this object for me”, “what is this?”, etc. Alternatively, gestures (e.g., thumbs up or thumbs down) with or without voice may also be used to change the context in a video as “uninteresting” or “interesting”. These sorts of tags may be used to determine content of interest to the user.
Embodiments, as described herein, may include, or may operate on, logic or a number of components, modules, or mechanisms. Modules are tangible entities (e.g., hardware) capable of performing specified operations when operating. A module includes hardware. In an example, the hardware may be specifically configured to carry out a specific operation (e.g., hardwired). In an example, the hardware may include configurable execution units (e.g., transistors, circuits, etc.) and a computer readable medium containing instructions, where the instructions configure the execution units to carry out a specific operation when in operation. The configuring may occur under the direction of the executions units or a loading mechanism. Accordingly, the execution units are communicatively may be coupled to the computer readable medium when the device is operating. In this example, the execution units may be a member of more than one module. For example, under operation, the execution units may be configured by a first set of instructions to implement a first module at one point in time and reconfigured by a second set of instructions to implement a second module.
Device (e.g., computer system) 1100 may include a hardware processor 1102 (e.g., a central processing unit (CPU), a graphics processing unit (GPU), a hardware processor core, or any combination thereof), a main memory 1104 and a static memory 1106, some or all of which may communicate with each other via an interlink (e.g., bus) 1108. The device 1100 may further include a display unit 1110, an input device 1112 (e.g., an alphanumeric keyboard), and a user interface (UI) navigation device 1114 (e.g., a mouse). In an example, the display unit 1110, input device 1112 and UI navigation device 1114 may be a touch screen display. The device 1100 may additionally include a storage device (e.g., drive unit) 1116, a signal generation device 1118 (e.g., a speaker), a network interface device 1120, and one or more sensors 1121, such as a global positioning system (GPS) sensor, compass, accelerometer, or other sensor. The device 1100 may include an output controller 1128, such as a serial (e.g., universal serial bus (USB), parallel, or other wired or wireless (e.g., infrared (IR), near field communication (NFC), etc.) connection to communicate or control one or more peripheral devices (e.g., a printer, card reader, etc.). The device 1100 may include one or more radios 1130 (e.g., transmission, reception, or transceiver devices). The radios 1130 may include one or more antennas to receive signal transmissions. The radios 1130 may be coupled to or include the processor 1102. The processor 1102 may cause the radios 1130 to perform one or more transmit or receive operations. Coupling the radios 1130 to such a processor may be considered configuring the radio 1130 to perform such operations. In general, an item being “caused” to perform an operation includes the item receiving data, interpreting the data as a command to perform an operation, and performing the operation. The signal does not have to be issued by the item that is causing the other item to perform the operation. Generally, “a first item causing a second item to perform an operation” means that the first item provided data that is already properly formatted to communicate with the second item or needs formatting and eventually becomes data that the second item receives and interprets as a command to perform the operation.
The storage device 1116 may include a machine readable medium 1122 on which is stored one or more sets of data structures or instructions 1124 (e.g., software) embodying or utilized by any one or more of the techniques or functions described herein. The instructions 1124 may also reside, completely or at least partially, within the main memory 1104, within static memory 1106, or within the hardware processor 1102 during execution thereof by the device 1100. In an example, one or any combination of the hardware processor 1102, the main memory 1104, the static memory 1106, or the storage device 1116 may constitute machine readable media.
While the machine readable medium 1122 is illustrated as a single medium, the term “machine readable medium” may include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) configured to store the one or more instructions 1124.
