## Title
Mixed reality interactions

## Abstract

Embodiments that relate to interacting with a physical object in a mixed reality environment via a head-mounted display are disclosed. In one embodiment a mixed reality interaction program identifies an object based on an image from captured by the display. An interaction context for the object is determined based on an aspect of the mixed reality environment. A profile for the physical object is queried to determine interaction modes for the object. A selected interaction mode is programmatically selected based on the interaction context. A user input directed at the object is received via the display and interpreted to correspond to a virtual action based on the selected interaction mode. The virtual action is executed with respect to a virtual object associated with the physical object to modify an appearance of the virtual object. The modified virtual object is then displayed via the display.

## Background
BACKGROUND
Searching for and retrieving relevant information using computing devices is a common task. Typical computing devices that are used to find and display information may include smartphones, tablets, notebook computers, and the like. Such computing devices, however, are typically limited to connecting a user to relevant information via dedicated graphical user interfaces and corresponding display elements, such as web search portals, hyperlinks, etc. These well-known interfaces and display elements generated by a corresponding computing device are tied to the device, and generally embody little or no context linking them to the user or the user's environment. Further, typical computing devices are fairly limited in their capacity to understand an environment in which they are used and/or to link user activity within the environment to information relevant to the user.
SUMMARY
Various embodiments are disclosed herein that relate to systems and methods for interacting with a physical object in a mixed reality environment. For example, one disclosed embodiment provides a method for interacting with a physical object in a mixed reality environment. The method includes providing a head-mounted display device operatively connected to a computing device, with the head-mounted display device including a display system for presenting the mixed reality environment and a plurality of input sensors including a camera for capturing an image of the physical object. A physical object is identified based on the captured image, and an interaction context is determined for the identified physical object based on one or more aspects of the mixed reality environment.
The method includes querying a stored profile for the physical object to determine a plurality of interaction modes for the physical object. The method includes programmatically selecting a selected interaction mode from the plurality of interaction modes based on the interaction context. A user input directed at the physical object is received via one of the input sensors of the head-mounted display device. The user input is interpreted to correspond to a virtual action based on the selected interaction mode.
The method further includes executing the virtual action with respect to a virtual object that is associated with the physical object to thereby modify the virtual object's appearance. The method then displays the virtual object via the head-mounted display device with the modified appearance.

DETAILED DESCRIPTION
FIG. 1 shows a schematic view of one embodiment of a mixed reality interaction system 10. The mixed reality interaction system 10 includes a mixed reality interaction program 14 that may be stored in mass storage 18 of a computing device 22. The mixed reality interaction program 14 may be loaded into memory 28 and executed by a processor 30 of the computing device 22 to perform one or more of the methods and processes described in more detail below.
The mixed reality interaction system 10 includes a mixed reality display program 32 that may generate a virtual environment 34 for display via a display device, such as the head-mounted display (HMD) device 36, to create a mixed reality environment 38. As described in more detail below, the virtual environment 34 may include one or more virtual objects, such as virtual object1 40, virtual object2 42, and geo-located target virtual object 52. Such virtual objects may include one or more virtual images, such as three-dimensional holographic objects and other virtual objects, as well as two-dimensional virtual images, that are generated and displayed by HMD device 36.
The computing device 22 may take the form of a desktop computing device, a mobile computing device such as a smart phone, laptop, notebook or tablet computer, network computer, home entertainment computer, interactive television, gaming system, or other suitable type of computing device. Additional details regarding the components and computing aspects of the computing device 22 are described in more detail below with reference to FIG. 5.
The computing device 22 may be operatively connected with the HMD device 36 using a wired connection, or may employ a wireless connection via WiFi, Bluetooth, or any other suitable wireless communication protocol. For example, the computing device 22 may be communicatively coupled to a network 16. The network 16 may take the form of a local area network (LAN), wide area network (WAN), wired network, wireless network, personal area network, or a combination thereof, and may include the Internet.
As described in more detail below, the computing device 22 may communicate with one or more other computing devices, such as server 20, via network 16. Additionally, the example illustrated in FIG. 1 shows the computing device 22 as a separate component from the HMD device 36. It will be appreciated that in other examples the computing device 22 may be integrated into the HMD device 36.
With reference now also to FIG. 2, one example of an HMD device 200 in the form of a pair of wearable glasses with a transparent display 44 is provided. It will be appreciated that in other examples, the HMD device 200 may take other suitable forms in which a transparent, semi-transparent or non-transparent display is supported in front of a viewer's eye or eyes. It will also be appreciated that the HMD device 36 shown in FIG. 1 may take the form of the HMD device 200, as described in more detail below, or any other suitable HMD device. Additionally, many other types and configurations of display devices having various form factors may also be used within the scope of the present disclosure. Such display devices may include hand-held smart phones, tablet computers, and other suitable display devices.
With reference to FIGS. 1 and 2, the HMD device 36 includes a display system 48 and transparent display 44 that enables images such as holographic objects to be delivered to the eyes of a user 46. The transparent display 44 may be configured to visually augment an appearance of a physical environment 50 to a user 46 viewing the physical environment through the transparent display. For example, the appearance of the physical environment 50 may be augmented by graphical content (e.g., one or more pixels each having a respective color and brightness) that is presented via the transparent display 44 to create a mixed reality environment.
The transparent display 44 may also be configured to enable a user to view a physical, real-world object, such as physical object1 54 and/or physical object2 58, in the physical environment 50 through one or more partially transparent pixels that are displaying a virtual object representation. As shown in FIG. 2, in one example the transparent display 44 may include image-producing elements located within lenses 204 (such as, for example, a see-through Organic Light-Emitting Diode (OLED) display). As another example, the transparent display 44 may include a light modulator on an edge of the lenses 204. In this example the lenses 204 may serve as a light guide for delivering light from the light modulator to the eyes of a user. Such a light guide may enable a user to perceive a 3D holographic image located within the physical environment 50 that the user is viewing, while also allowing the user to view physical objects in the physical environment, thus creating a mixed reality environment.
The HMD device 36 may also include various sensors and related systems. For example, the HMD device 36 may include an eye-tracking system 62 that utilizes at least one inward facing sensor 216. The inward facing sensor 216 may be an image sensor that is configured to acquire image data in the form of eye-tracking data 66 from a user's eyes. Provided the user has consented to the acquisition and use of this information, the eye-tracking system 62 may use this information to track a position and/or movement of the user's eyes.
In one example, the eye-tracking system 62 includes a gaze detection subsystem configured to detect a direction of gaze of each eye of a user. The gaze detection subsystem may be configured to determine gaze directions of each of a user's eyes in any suitable manner. For example, the gaze detection subsystem may comprise one or more light sources, such as infrared light sources, configured to cause a glint of light to reflect from the cornea of each eye of a user. One or more image sensors may then be configured to capture an image of the user's eyes.
Images of the glints and of the pupils as determined from image data gathered from the image sensors may be used to determine an optical axis of each eye. Using this information, the eye-tracking system 62 may then determine a direction and/or at what physical object or virtual object the user is gazing. Such eye-tracking data 66 may then be provided to the computing device 22. It will be understood that the gaze detection subsystem may have any suitable number and arrangement of light sources and image sensors.
The HMD device 36 may also include sensor systems that receive physical environment data 60 from the physical environment 50. For example, the HMD device 36 may include an optical sensor system 68 that utilizes at least one outward facing sensor 212, such as an optical sensor, to capture image data 74. Outward facing sensor 212 may detect movements within its field of view, such as gesture-based inputs or other movements performed by a user 46 or by a person or physical object within the field of view. Outward facing sensor 212 may also capture two-dimensional image information and depth information from physical environment 50 and physical objects within the environment. For example, outward facing sensor 212 may include a depth camera, a visible light camera, an infrared light camera, and/or a position tracking camera.
The HMD device 36 may include depth sensing via one or more depth cameras. In one example, each depth camera may include left and right cameras of a stereoscopic vision system. Time-resolved images from one or more of these depth cameras may be registered to each other and/or to images from another optical sensor such as a visible spectrum camera, and may be combined to yield depth-resolved video.
In other examples a structured light depth camera may be configured to project a structured infrared illumination, and to image the illumination reflected from a scene onto which the illumination is projected. A depth map of the scene may be constructed based on spacings between adjacent features in the various regions of an imaged scene. In still other examples, a depth camera may take the form of a time-of-flight depth camera configured to project a pulsed infrared illumination onto a scene and detect the illumination reflected from the scene. It will be appreciated that any other suitable depth camera may be used within the scope of the present disclosure.
Outward facing sensor 212 may capture images of the physical environment 50 in which a user 46 is situated. In one example, the mixed reality display program 32 may include a 3D modeling system that uses such input to generate a virtual environment 34 that models the physical environment 50 surrounding the user 46.
The HMD device 36 may also include a position sensor system 72 that utilizes one or more motion sensors 220 to capture position data 76, and thereby enable motion detection, position tracking and/or orientation sensing of the HMD device. For example, the position sensor system 72 may be utilized to determine a direction, velocity and acceleration of a user's head. The position sensor system 72 may also be utilized to determine a head pose orientation of a user's head. In one example, position sensor system 72 may comprise an inertial measurement unit configured as a six-axis or six-degree of freedom position sensor system. This example position sensor system may, for example, include three accelerometers and three gyroscopes to indicate or measure a change in location of the HMD device 36 within three-dimensional space along three orthogonal axes (e.g., x, y, z), and a change in an orientation of the HMD device about the three orthogonal axes (e.g., roll, pitch, yaw).
Position sensor system 72 may also support other suitable positioning techniques, such as GPS or other global navigation systems. Further, while specific examples of position sensor systems have been described, it will be appreciated that other suitable position sensor systems may be used. In some examples, motion sensors 220 may also be employed as user input devices, such that a user may interact with the HMD device 36 via gestures of the neck and head, or even of the body. The HMD device 36 may also include a microphone system 80 that includes one or more microphones 224 that capture audio data 82. In other examples, audio may be presented to the user via one or more speakers 228 on the HMD device 36.
The HMD device 36 may also include a processor 230 having a logic subsystem and a storage subsystem, as discussed in more detail below with respect to FIG. 5, that are in communication with the various sensors and systems of the HMD device. In one example, the storage subsystem may include instructions that are executable by the logic subsystem to receive signal inputs from the sensors and forward such inputs to computing device 22 (in unprocessed or processed form), and to present images to a user via the transparent display 44.
It will be appreciated that the HMD device 36 and related sensors and other components described above and illustrated in FIGS. 1 and 2 are provided by way of example. These examples are not intended to be limiting in any manner, as any other suitable sensors, components, and/or combination of sensors and components may be utilized. Therefore it is to be understood that the HMD device 36 may include additional and/or alternative sensors, cameras, microphones, input devices, output devices, etc. without departing from the scope of this disclosure. Further, the physical configuration of the HMD device 36 and its various sensors and subcomponents may take a variety of different forms without departing from the scope of this disclosure.
With reference now to FIG. 3, descriptions of example use cases and embodiments of the mixed reality interaction system 10 will now be provided. FIG. 3 provides a schematic illustration of a user 304 located in a physical environment 50 that comprises an office 308, with the user experiencing a mixed reality environment 38 via an HMD device 36 in the form of HMD device 200. As discussed in more detail below, in FIG. 3 the mixed reality environment 38 may comprise the office 308 and one or more physical objects, as well as a virtual environment including one or more virtual objects.
In the example illustrated in FIG. 3, the user 304 sits at a desk 312 that includes a framed photograph 316 of the user's spouse and a keyboard 320. The optical sensor system 68 of the HMD device 200 may capture image data 74 from the office 308, including image data representing the photograph 316 and other physical objects in the office, such as table 324, book 328 on the table, basketball 332, bookcase 334 and coat rack 338. Image data 74 of one or more of these physical objects may be provided by the HMD device 200 to the mixed reality interaction program 14.
Using this image data 74, the mixed reality interaction program 14 may identify one or more of these physical objects. For example, the mixed reality interaction program 14 may identify the photograph 316 and the face of the user's spouse in the photograph by comparing image data 74 of the face to stored face image data and corresponding identities located on server 20. In this example, the mixed reality interaction program 14 may include a face detection subsystem that detects face images in the image data 74. To detect a face image in the image data 74, the face detection subsystem may use any suitable face detection technologies and/or algorithms including local binary patterns (LBP), principal component analysis (PCA), independent component analysis (ICA), evolutionary pursuit (EP), Elastic Bunch Graph Matching (EBGM), or other suitable algorithm or combination of algorithms.
The face detection program may access object profile data 92 on server 20 to match image data 74 including the face in photograph 316 with one or more images and related user profile information corresponding to user's spouse. It will be appreciated that the face detection program may use any suitable facial recognition techniques to match image data 74 with stored images of the user's spouse.
The mixed reality interaction program 14 also determines an interaction context 84 for the framed photograph 316 based on one or more aspects of the mixed reality environment 38. With reference again to FIG. 1, such aspects of the mixed reality environment 38 may include one or more data feeds 86 originating from the mixed reality environment 38 or externally to the mixed reality environment. Data feeds 86 may include temporal data, such as time of day, day of week, month, season, etc., social networking data, such as postings, status updates, etc. related to user 304, location data, weather data, etc.
In some examples and with reference to FIG. 3, such aspects of the mixed reality environment 38 may also include information more directly linked to the office 308. Such information may include the presence of one or more other persons in the office 308, the identities of such persons, an ambient light level, an ambient noise level, etc. In other examples, such aspects of the mixed reality environment 38 may also include information related to the user 304, such as user biometric parameters including, for example, heart rate, pupillary response, hemoglobin saturation, skin conductivity, respiration, perspiration, and brainwave activity.
In one example, the mixed reality interaction program determines that a current time of day is 10:30 am in the mixed reality environment 38. It will be appreciated that the time of day may be determined, for example, by an internal clock within computing device 22 or may be received from an external source via data feeds 86. Accordingly, in the present example the mixed reality interaction program 14 uses the current time of day of 10:30 am to determine a Business-Time interaction context for the photograph 316.
Having identified the face of the user's spouse in the photograph 316, the mixed reality interaction program 14 may then query a stored profile of the user's spouse in object profile data 92 to determine a plurality of interaction modes 88 that are available for the photograph 316. As described in more detail below, each of the plurality of interaction modes 88 may correspond to a different virtual action 90 that may be taken with respect to the photograph 316. In the present example, the available interaction modes 88 may include a Family Calendar interaction mode and a Family Reunion Planning interaction mode. In other examples, the mixed reality interaction program 14 may create a new profile for the photograph 316 that associates one or more interaction modes with the photograph. For example, the mixed reality interaction program 14 may enable the user 304 to create a new profile for the photograph 316 when, for example, a relationship status has changed.
Next, based on the determined interaction context, the mixed reality interaction program 14 may programmatically select a selected interaction mode. In the present example, with the determined interaction context being Business-Time, the mixed reality interaction program 14 programmatically selects a Family Calendar interaction mode. In one example, the Business-Time interaction context may be defined as a time of day falling between 8:00 am and 6:00 pm. The mixed reality interaction program 14 may be configured to pair the Business-Time interaction context with the Family Calendar interaction mode with respect to the photograph 316.
Another interaction context, a Personal-Time interaction context, may be defined as a time of day falling between 6:01 pm and 7:59 am. The mixed reality interaction program 14 may be configured to pair the Personal-Time interaction context with a Family Reunion Planning interaction mode with respect to the photograph 316.
In the present example, the mixed reality interaction program 14 may receive a user input from user 304 that is directed at the photograph 316. For example, the mixed reality interaction program 14 may receive eye-tracking data 66 from the HMD device 200 indicating that the user 304 is gazing at the photograph 316, as indicated by gaze line 336. In other examples, the user input may take one or more other forms including, for example, position data 76 and image data 74. The position data 76 may include head pose data indicating that the user 304 is facing the photograph 316. The image data 74 may include image data showing the user 304 pointing or gesturing at the photograph 316. It will be appreciated that other forms of user input may similarly be utilized.
The mixed reality interaction program 14 may then interpret the user 304 gazing at the photograph 316 to correspond to a virtual action 90. The virtual action 90 may be based on the selected interaction mode, in this example the Family Calendar interaction mode. The virtual action 90 may comprise presenting to the user 304 a virtual object in the form of the user's family calendar stored in a calendar application. It will be appreciated that the user's family calendar is associated with the photograph 316 of the user's spouse.
The mixed reality interaction program 14 may then execute the virtual action 90 with respect to a virtual instantiation of the user's family calendar to modify an appearance of the calendar. For example, to comfortably display the user's family calendar to the user 304, the mixed reality interaction program 14 may control the mixed reality display program 32 to scale the virtual instantiation of the calendar to a predetermined size. The mixed reality interaction program 14 may then display the virtual instantiation of the user's family calendar with the modified appearance, as indicated at 340, via the mixed reality display program 32 and HMD device 200.
In other examples, the mixed reality interaction program 14 may enable the user 304 to create and add new virtual actions 90 that are associated with the photograph 316. For example, the user 304 may create a virtual action that includes highlighting family members' birthdays on the family calendar. Thereafter, when the user 304 gazes at the photograph 316, the mixed reality interaction program 14 will highlight family members' birthdays on the displayed family calendar.
In one example, the mixed reality interaction program 14 may geo-locate the family calendar 340 in physical proximity to the photograph 316. As shown in FIG. 3, in the present example the calendar 340 may be displayed just above the photograph 316 such that when the user 304 gazes at the photograph, the calendar is presented in an easily viewable location just above the photograph. Being geo-located to the photograph 316, the calendar 340 may remain “tethered” to the photograph and may track the location of the photograph in the office 308. Advantageously, if the photograph 316 is moved to another location in the office 308, the user 304 may still easily recall and view the calendar 340 by gazing at the photograph 316.
In another example, the user 304 may use his right hand 344 to point at the basketball 332 near wall 348. The mixed reality interaction program 14 may identify the basketball, determine an interaction context for the basketball, query a stored profile for the basketball, and programmatically select a selected interaction mode based on the interaction context in a manner similar to that described above for the photograph 316. A camera in the HMD device 200 may capture image data 74 showing the user's right hand 344 pointing at the basketball 332. The mixed reality interaction program 14 may interpret this user input to correspond to displaying a website of the user's favorite basketball team.
The mixed reality interaction program 14 may then modify image data of the website to, for example, enhance the contrast of the displayed website when displayed above the basketball and in front of the wall 348. The mixed reality interaction program 14 may then display a holographic version of the modified website 352 above the basketball 332. The website 352 may also be geo-located to the basketball 332 such that it follows the basketball to different locations in the office 308, as indicated by basketball 332′ and website 352′ located near the left rear corner of the office.
In some examples, the mixed reality interaction program 14 may be unable to determine the identity of a physical object, or may determine an incomplete identity of the object. For example, the mixed reality interaction program 14 may not recognize a visitor 342 who enters the office 308. The mixed reality interaction program 14 may also determine that the user 304 currently has a meeting in the office 308 scheduled in the user's calendar with a John Doe. Based on this meeting, the mixed reality interaction program 14 may then query the user 304, “Is this John Doe?” via text displayed on the HMD device 200. The user 304 may provide a confirmation of the identity of the visitor 342 by, for example, nodding, speaking “Yes”, or by any other suitable input.
In another example, where the user 304 does not confirm that the visitor 342 is John Doe, the mixed reality interaction program 14 may present another query to the user requesting the identity of the visitor. When the user 304 answers and provides an identity of the visitor, such as, “This is John Smith,” the program may then associate the identity John Smith with the visitor. It will also be appreciated that such identity confirmation processes may be used with any other physical objects.
In another example, the mixed reality interaction program 14 may determine a change in the interaction context 84 and may correspondingly change the interaction mode 86. For example, the user 304 may be working in the office 308 late one night. At 7:01 pm the mixed reality interaction program 14 determines that the interaction context changes from Business-Time to Personal-Time. Accordingly, the mixed reality interaction program 14 may programmatically select the Family Reunion Planning interaction mode with respect to the photograph 316.
The mixed reality interaction program 14 may then interpret the user 304 gazing at the photograph 316 to correspond to a virtual action 90 that is based on the Family Reunion Planning interaction mode. In this example, the virtual action 90 may comprise highlighting the dates 364 of the user's family reunion gathering in the user's family calendar 340. The mixed reality interaction program 14 may then execute the virtual action with respect to the calendar 340 to modify an appearance of the calendar. For example, the mixed reality interaction program 14 may control the mixed reality display program 32 to highlight in flashing color the dates 364 of the family reunion gathering in the calendar 340. The mixed reality interaction program 14 may then render and display the calendar 340 with the highlighted dates 364 via the mixed reality display program 32.
In another example, after determining a change in the interaction context 84 to the Family Reunion Planning interaction mode, the mixed reality interaction program 14 may execute a different virtual action 90 with respect to a different virtual object that is associated with the photograph 316. For example, the mixed reality interaction program 14 may display a virtual family reunion To-Do List 360 via the mixed reality display program 32 and HMD device 200 to the user 304. As with the family calendar 340, the mixed reality interaction program 14 may control the mixed reality display program 32 to scale a virtual instantiation of the family reunion To-Do List 360 to a predetermined size. The mixed reality interaction program 14 may then display the To-Do List 360, via the mixed reality display program 32 with the modified appearance.
In another example, the user 304 may desire to manually switch between the Family Calendar interaction mode and the Family Reunion Planning interaction mode. The user may request that the current Family Calendar interaction mode be modified by, for example, speaking “Switch to Family Reunion Planning.” The mixed reality interaction program 14 interprets this user input as a request to modify the interaction mode, and changes the interaction mode accordingly. The user may then point at the photograph 316, which is captured as image data 74 via the HMD device 200. The mixed reality interaction program 14 interprets this user input as corresponding to a virtual action 90 based on the Family Reunion Planning interaction mode, such as displaying the virtual family reunion To-Do List 360. The mixed reality interaction program 14 may then execute the virtual action and display the family reunion To-Do List 360 with a modified appearance as described above.
In another example, the mixed reality interaction program 14 may display a target virtual object that may function to enable user interaction with another virtual object in a manner similar to that described above. For example, the mixed reality interaction program 14 may display a geo-located target virtual object 52 in the form of a holographic wizard 370 located on table 324 in the mixed reality environment 38. The mixed reality interaction program 14 may then determine a Business-Time interaction context for the wizard 370 based on one or more aspects of the mixed reality environment 38.
The mixed reality interaction program may query a stored profile of the holographic wizard 370 in the object profile data 92 to determine a plurality of interaction modes 88 that are available for the wizard. In the present example, the available interaction modes 88 may include a Stock Market interaction mode and a Movie Listings interaction mode. Next, based on the determined interaction context, the mixed reality interaction program 14 may programmatically select a selected interaction mode. In the present example, with the determined interaction context being Business-Time, the mixed reality interaction program 14 programmatically selects the Stock Market interaction mode.
In the present example, the mixed reality interaction program 14 may receive a user input from user 304 that is directed at the holographic wizard 370, such as position data 76 including head pose data indicating that the user's face is oriented toward the wizard 370. The mixed reality interaction program 14 may then interpret the user 304 facing the wizard 370 to correspond to a virtual action 90 that is based on the selected interaction mode, in this example the Stock Market interaction mode, and is associated with the wizard 370. The virtual action 90 may comprise presenting a stock market summary 374 via the mixed reality display program 32 and HMD device 200 to the user 304.
The mixed reality interaction program 14 may then execute the virtual action 90 with respect to the stock market summary to, for example, highlight quotes of stocks owned by the user 304, such as the XYZ stock quote 376. The mixed reality interaction program 14 may control the mixed reality display program 32 to highlight the XYZ stock quote 376. The mixed reality interaction program 14 may then display the stock market summary 374 via the mixed reality display program 32.
In another example, the mixed reality interaction program 14 may also use a user input to create an association between a physical object and a selected interaction mode. With continued reference to FIG. 3, in one example the user 304 may desire to associate the basketball 332 with the Anytown Ants website 352. The user 304 may pick up the basketball 332 and rotate the basketball in the user's hands.
Using image data 74, the mixed reality interaction program 14 may recognize the user's rotation of the basketball 332 as a trigger to display to the user 304 the available interaction modes 88 for the basketball. Such interaction modes 88 may include, for example, displaying the Anytown Ants website, displaying a scoreboard of current basketball games, and displaying a calendar showing upcoming games in the user's basketball league. The user 304 may then select the Anytown Ants website interaction mode to associate with the basketball 332 via user input received by the HMD device 200. Accordingly, the mixed reality interaction program 14 may then be configured to associate the basketball 332 with the Anytown Ants website interaction mode. Subsequently, the mixed reality interaction program 14 may execute a virtual action with respect to the Anytown Ants website that is associated with the basketball 332 when user input directed at the basketball 332 is received, as described above.
It will be appreciated that the present system may enhance a user's ability to associate particular information sources, portals, etc. with objects in the mixed reality environment 38, whether physical objects or virtual objects. For example, by linking the holographic wizard 370 with a displayed stock market summary, the user may more easily remember to use the wizard to see the stock market summary during business hours. The user may, for example, memorize the phrase, “I'm a Wizard of the stock market” to provide an easily-remembered cognitive link between the holographic wizard 370 in the user's office 308 and the stock market summary.
In another example, the mixed reality interaction program 14 may generate audio feedback that is perceived by the user 304 as originating from a virtual object or physical object in the office 308. The mixed reality interaction program 14 may utilize a three-dimensional audio positioning technique, such as a head-related transfer function, to generate such audio feedback via speakers 228 of the HMD 200. In one example, the mixed reality interaction program 14 may generate audio comprising a broadcast of an Anytown Ants basketball game that is perceived by the user 304 as originating from the virtual website 352 or the basketball 332.
In another example, the mixed reality interaction program 14 may be configured to take a virtual action with respect to an object that is placed on the table 324. With reference to FIG. 3, the mixed reality interaction program 14 may recognize that book 328 is resting on the table 324. Accordingly, based on the book 328 resting on the table 324, the mixed reality interaction program 14 may programmatically post a status update to the user's social network that notes that the user 304 is currently reading book 328.
In another example, the mixed reality interaction program 14 may be configured to take a virtual action when a state of an object changes. For example, the mixed reality interaction program 14 may identify that the user 304 has begun drinking his regular cup of morning coffee at 6:30 am. The program may monitor the amount of coffee remaining in the user's cup. If a predetermined amount of coffee is remaining in the cup and the user attempts to check email, the program may prevent or dissuade the user from checking email. For example, upon detecting an attempt to check email, the program may display a message to the user asking, “Wouldn't you like to finish your relaxing cup of coffee first?”
In another example, a document related to a work project managed by the user 304 may be linked to the user, such as in the object profile data 92. A fellow team member of the work project may also wear an HMD device 200 that is communicatively coupled to a mixed reality interaction program 14. When the fellow team member sees the user 304, the team member's mixed reality interaction program 14 recognizes the user 304 and displays the document related to the work project via the team members' HMD device 200.
In another example, a team member may virtually deliver a document to the user 304 via leaving a physical or virtual object on the user's desk 312. For example, a team member of the user 304 may associate the document with a cardboard cutout of the letter “D.” The team member may leave the cutout D on the user's desk 312 while the user 304 is away. Upon returning to the office 308, the user's HMD device 200 may recognize the cutout D. The HMD device 200 may indicate to the user 304 that the cutout D is actively linked to virtual information by, for example, animating the cutout D, such as by causing the cutout D to glow when viewed. The user 304 may request to view the linked virtual information, and the HMD device 200 may then access the document linked to the cutout D, and may display the document for the user 304.
In another example, the user 304 may provide a user input that applies to multiple virtual objects associated with multiple physical objects. For example and with reference to FIG. 3, the user 304 may desire to dim all of the virtual objects displayed in the office 308. The user 304 may extend his right hand 344 outwardly and lower his hand toward the desk 312. The mixed reality interaction system 10 may recognize this gesture, and may correspondingly dim all of the virtual objects displayed via HMD 200.
In another example, when the user 304 gazes at the basketball 332, the mixed reality interaction program 14 may interpret the user's gaze to correspond with displaying over the basketball a virtual volume control knob. The volume control knob may be virtually rotated by the user 304 to adjust the volume of the broadcast of the Anytown Ants basketball game to which the user is listening. The current volume may also be displayed as a digital volume indicator 380. In another example, the user 304 may pick up and physically rotate the basketball 332 to correspondingly adjust the volume of the broadcast via the virtual volume control knob.
In another example, while the user 304 is away from the office 308, the visitor 342 may pick up and rotate the basketball 332 to lower the volume of the basketball game broadcast that is being delivered by speakers in the room 308. When the user 304 returns to the office 308, the mixed reality interaction program 14 may identify the new orientation of the basketball 332 and correspondingly lower the volume of the broadcast being delivered to the user via HMD 200. The program may also correspondingly modify the volume indicator 380.
