## Background
BACKGROUND
The present disclosure relates generally to motion-sensing display apparatuses. In particular, motion-sensing display apparatuses supported near a user's eye that execute computer executable instructions in response to user gestures are described.
Known motion-sensing display apparatuses are not entirely satisfactory for the range of applications in which they are employed. Some existing display apparatuses are configured to interface with motion-sensing technologies, such as the Microsoft® Kinect® system. Many such apparatuses, however, do not provide a display proximate a user's eye. As a result, these devices are often ill-suited for displaying images that encompass large portions of a user's field of vision. Further, conventional motion sensing technology is generally large and not portable, limiting its use outside of a user's home or during physical activities.
Often, these displays include an opaque backing that prevents a user from seeing beyond the display. As a result, these devices are often unable augment or overlay scenes within the user's field of vision. Other devices may use a camera to capture a scene beyond the display and augment this captured scene on a display. This often results in unnatural and unreliable displays, however.
Certain display apparatuses are mounted near a user's eye with a piece of eyewear. These devices often produce a display that encompass a large portion of a user's field of vision. These devices, however, often include an opaque backing, preventing the ability to augment natural scenes and view user motions or gestures occurring beyond the screen. This, commonly in conjunction with the use of unwieldy accessories, leads to poor motion capture capabilities (if any exist at all).
Some other devices mounted on a piece of eyewear, such as Vuzix® brand eyewear devices, provide a display on a partially transparent screen. However, these devices often lack support for image capturing and motion sensing functionality. By extension, they often lack the ability to execute computer instructions in response to motion or natural images, including the ability to manipulate the display.
Thus, there exists a need for motion-sensing display apparatuses that improve upon and advance the design of known motion-sensing devices and display devices. Examples of new and useful motion-sensing display apparatuses relevant to the needs existing in the field are discussed below.
SUMMARY
The present disclosure is directed to motion-sensing display apparatuses supported near a user's eye including partially transparent screens at least partially disposed within the user's field of vision, image generators positioned to display an image on a first side of the screen, motion capture devices positioned near the screen and configured to capture a user gesture occurring beyond the screen in the user's field of vision, and processors in data communication with the image generator and the motion capture device, the processors configured to execute computer executable instructions in response to the user gesture. In some examples, motion-sensing display apparatuses include cameras. In some further examples, image generators display user interfaces on screens.

With reference to FIG. 1, motion-sensing display apparatus 100 is designed to display an image near a user 101's eye and execute computer executable instructions in response user gestures by incorporating motion and image capture features. As FIG. 2 illustrates, motion-sensing display apparatus 100 includes an eyewear article 110, a processor 160, a lens 120, an image generator 130, a motion capture device 140, and a microphone 150. Motion-sensing display apparatus 100 is configured to capture user gestures, along with other objects within a captured scene, and execute computer processes in response to the captured objects. This may involve manipulating a display produced by image generator 130 on lens 120. Motion-sensing display apparatus 100 may additionally execute computer processes in response to audio captured by microphone 150. By incorporating these capturing technologies, motion-sensing display apparatus 100 provides a new and useful way of displaying and controlling computer images and processes.
As FIG. 1 illustrates, eyewear article 110 supports motion-sensing display apparatus 100 on user 101's head. Looking to FIG. 2, eyewear article 110 includes a first temple 112, a second temple 113, and a bar 114 extending between the two temples. As FIG. 1 illustrates, first temple 112 and second temple 113 extend from eyewear article 110 to rest on user 101's ears, providing support for motion-sensing display apparatus 100.
As FIG. 2 illustrates, processor 160 is supported by bar 114. Processor 160 is configured execute computer executable instructions, and may, by extension, control the electronic elements of motion-sensing display apparatus 100.
Processor 160 may acquire data from other elements of motion-sensing display apparatus 100 or from external sources and execute computer executable code in response to this data. For example, processor 160 is configured to acquire data from motion capture device 140 such as data that corresponds to a user gesture. Processor 160 may additionally or alternatively acquire data from microphone 150. In some examples, the processor acquires data from a separate device, such as a portable music player, a personal data assistant, a smart phone, a global positioning system, or the like.
Processor 160 is in data communication with image generator 130 and may instruct image generator 130 to generate and manipulate a display projected on lens 120. As FIG. 3 illustrates, processor 160 may, for example, generate a user interface 170 on lens 120. Processor 160 may acquire data from other elements of motion-sensing display apparatus 100 and manipulate the user interface in response to this data.
As FIG. 1 illustrates, eyewear article 110 supports lens 120 substantially near user 101's eyes. As FIG. 3 shows, lens 120 defines a partially transparent screen 122 at least partially disposed within user 101's field of vision. Because screen 122 is partially transparent, a user is able to view objects beyond screen 122, which may include, for example, gestures being performing and other objects within his environment.
As FIG. 2 illustrates, image generator 130 is attached to first temple 112 and is substantially aligned with screen 122. As FIG. 2 shows, a second image generator, image generator 131, is attached to second temple 113 to project images on screen 122 distal image generator 130. This disclosure specifically contemplates positioning additional image generators augment the expanse of generated images over a screen's surface area. Image generator 130 is configured to display images on a first side of screen 122 facing user 101's eye in response to instructions executed by processor 160. These images often may overlay and/or augment a naturally viewed scene within user 101's field of vision. Image generator 130 may display both opaque and partially transparent images on screen 122.
FIG. 3 illustrates a representative set of images generated by image generator 130; the generated images include a user interface 170 that overlays and augments a scene 102 within user 101's field of vision. User interface 170 may include one or more opaque or partially transparent screen elements that overlay a portion of scene 102 while providing user 101 a partially unobstructed view of scene 102. As FIG. 3 illustrates, certain elements of user interface 170 allow user 101 to view elements behind displayed elements.
As FIG. 2 illustrates, motion capture device 140 is affixed to bar 114 and is oriented away from user 101 when user 101 is wearing eyewear article 110 to capture images and motion occurring beyond screen 122. As FIG. 2 shows, motion capture device 140 includes an image sensor 142 including a camera, a light source 144, and a depth sensor 146. Motion capture device 140 captures scene 102, which comprises everything viewable by motion capture device 140. FIG. 3 illustrates an example of such a scene.
As FIG. 2 shows, image sensor 142 is supported by bar 114 and oriented away from user 101 as user 101 wears eyewear article 110. Image sensor 142 is configured to capture an image from a scene and communicate data corresponding to the captured image to processor 160. Image sensor 142 is not limited to capturing light within the visual spectrum. Image sensor 142 may, for example, capture infrared or ultraviolet light reflected on a scene from an artificial light source.
As FIG. 2 shows, light source 144 is supported by bar 114 and is substantially aligned with image sensor 142. Light source 144 is configured to project light onto a scene. This light is reflected from the scene and may be captured by motion capture device 140. This may allow motion capture device 140 to more accurately capture images and motion present within the scene. Light source 144 is capable of projecting visual light as well as light outside the visual spectrum, which may improve capturing accuracy without altering the scene's natural appearance.
As FIG. 2 illustrates, depth sensor 146 is supported by bar 114 and is horizontally spaced from image sensor 142. Depth sensor 146 is configured to capture images and motion from a scene at a different angle than image generator 130. The data captured from this second viewpoint allows processor 160 to compare the data communicated by depth sensor 146 to the data communicated by image sensor 142 to better detect objects' depth in the captured scene.
As FIGS. 3-5 illustrate, motion capture device 140 may capture images and motion that correspond to a user gesture, such as a gesture 191, a gesture 192, a gesture 193, and/or a gesture 194. Upon capturing a gesture, motion capture device 140 communicates data corresponding to the gesture to processor 160, which executes computer executable instructions in response to received data.
For example, FIG. 3 illustrates a first hand 105 of user 101 performing gesture 191 as image generator 130 generates user interface 170 including a radio button 180 adjacent to a caption reading “OPEN BROWSER.” User 101 performs gesture 191 by extending two fingers beyond screen 122 to align with a selected screen element, such as radio button 180, in the user's field of vision. As user 101 extends his fingers, motion capture device 140 captures this motion and communicates data corresponding to this gesture to processor 160. Processor 160 then executes computer executable instructions in response to this data. In this example, processor 160 selects radio button 180 in response to gesture 191.
FIG. 3 illustrates a second hand 103 performing gesture 192 in concert with gesture 191. As gesture 192 shows, motion-sensing display apparatuses may capture multiple gestures being operated in concert. As FIG. 3 shows, gesture 192 is similar to gesture 191, wherein hand 103 extends two fingers beyond screen 122 and aligned with a button 181 reading “OPEN WORD PROCESSOR” in user interface 170. As user 101 extends fingers of his second hand, motion capture device 140 communicates data relating to this gesture to processor 160, and processor 160 executes computer executable instructions to launch a word browsing application in response.
FIG. 4 illustrates gesture 193, which is captured and processed similar to gesture 191. User 101 performs gesture 193 by extending a single finger to align with a screen element, window 182, at a first position 195 within user interface 170 and moving the extended finger to align with a second position 196 within user interface 170. In response, processor 160 moves window 182 from its original position proximate first position 195 to a second position proximate second position 196.
FIG. 4 illustrates gesture 194, which is also captured and processed similar to gesture 191. User 101 performs gesture 193 by extending all of his fingers to align with user interface 170 and swiping the full hand horizontally across screen 122. In response, processor 160 changes the display on screen 122 from a first display window 185 to a second display window 186, wherein each display window includes a collection of screen elements. In this example, first display window 185 includes a button for “OPEN BROWSER,” which is displayed prior to swiping the full hand and removed after Likewise, second display window 186 includes a button for “OPEN WORD PROCESSOR” in this example, which appears after swiping the hand. This is designed to provide similar functionality to screen switching available on many mobile phone platforms.
As gesture 192 illustrates, motion-sensing display apparatus 100 is capable of distinguishing a user from the remainder of a captured scene. For example, motion-sensing display apparatus 100 may distinguish between different users, such as when a person other than the user performs a second user gesture in the view of motion capture device 140. FIG. 1 displays such an example, wherein both user 101 and a second user 199 are performing gestures. Motion capture device 140 is configured to capture user 101's gestures as well as second user gesture 198. This disclosure additionally or alternatively contemplates gestures that incorporate multiple movements, which may be performed by multiple parts of a user's body. For example, gestures may incorporate actions by a user's hands and/or feet. Processor 160 configured to execute computer executable instructions in response these captured images and motions, which may include second user gesture 198.
Processor 160 may additionally store captured data to learn a user's features. In certain examples, users may verify processor 160's user differentiating functionality to train processor 160 to better differentiate users.
As FIG. 3 illustrates, motion-sensing display apparatus 100 is not specifically restricted to capturing user gestures. Motion-sensing display apparatus 100 may capture any element of a captured scene and communicate data related to that element to processor 160. Processor 160 may then execute computer executable instructions in response to the captured element. For example, FIG. 3 illustrates motion capture device 140 capturing a scene including a tree 104. As FIG. 3 shows, processor 160 executes computer executable code to display a dialog 106 in response to capturing the tree. This disclosure specifically contemplates gesture based interaction with dialogs displayed in response to captured elements in a scene, such as dialog 106.
As FIG. 2 illustrates, microphone 150 is supported by bar 114. Microphone 150 defines an opening substantially aligned with motion capture device 140 that allows sound to reach microphone 150. Microphone 150 captures audio data as motion capture device 140 operates. Microphone 150 communicates captured data to processor 160, which may execute computer executable instructions in response. Processor 160 may act in response to the audio data either alone or in concert with data captured by motion capture device 140. Processor 160 may, for example, respond to a user's vocal commands or respond to noises present in motion-sensing display apparatus 100's environment.
With reference to FIG. 6, a second example of a motion-sensing display apparatus, motion-sensing display apparatus 200, will now be described. Motion-sensing display apparatus 200 includes many similar or identical features to motion-sensing display apparatus 100. Thus, for the sake of brevity, each feature of motion-sensing display apparatus 200 will not be redundantly explained. Rather, key distinctions between motion-sensing display apparatus 200 and motion-sensing display apparatus 100 will be described in detail and the reader should reference the discussion above for features substantially similar between the two motion-sensing display apparatuses.
As FIG. 6 shows, motion-sensing display apparatus 200 provides a motion-sensing display substantially similar to motion-sensing display apparatus 100. Motion-sensing display apparatus 200 includes a processor 260 and a motion capture device 240, each substantially similar to the corresponding elements of motion-sensing display apparatus 200. Motion-sensing display apparatus 200, however, additionally includes a motion capture accessory 299.
Motion capture accessory 299 is configured to augment motion capture device 240 in capturing the gesture. Motion capture accessory 299 defines a glove in data communication with processor 260. As FIG. 6 shows, this disclosure additionally or alternatively contemplates the use of more than one accessory; motion-sensing display apparatus 200 includes, for example, a second accessory 298 defining a glove on the opposite hand of motion capture accessory 299. Both accessories may include movement sensors, such as accelerometers or gyroscopes, to capture data relating to user movement and communicate this data to processor 260. This allows processor 260 to respond to user movement more precisely.
As FIG. 6 shows, motion capture accessory 299 includes a transmitter 297 configured to communicate wirelessly with a receiver 296 proximate to and in data communication with processor 260. This allows motion capture accessory 299 to communicate any captured data to processor 260.
Accessories may additionally include elements that allow motion capture device 240 to track its position more accurately. Such elements may be bodies attached to the exterior of the accessories. Accessories may additionally or alternatively be constructed of a material selected for increased compatibility with motion capture device 240. Such accessories may assist motion capture device 240 in capturing the movement, location, and shape of the relevant parts of the user or of the accessory without requiring a data connection with processor 160.
