This disclosure generally relates to devices and methods for capturing and processing images and audio from an environment of a user, and using information derived from captured images and audio.
Today, technological advancements make it possible for wearable devices to automatically capture images and audio, and store information that is associated with the captured images and audio. Certain devices have been used to digitally record aspects and personal experiences of one's life in an exercise typically called “lifelogging.” Some individuals log their life so they can retrieve moments from past activities, for example, social events, trips, etc. Lifelogging may also have significant benefits in other fields (e.g., business, fitness and healthcare, and social research). Lifelogging devices, while useful for tracking daily activities, may be improved with capability to enhance one's interaction in his environment with feedback and other advanced functionality based on the analysis of captured image and audio data.
Even though users can capture images and audio with their smartphones and some smartphone applications can process the captured information, smartphones may not be the best platform for serving as lifelogging apparatuses in view of their size and design. Lifelogging apparatuses should be small and light, so they can be easily worn. Moreover, with improvements in image capture devices, including wearable apparatuses, additional functionality may be provided to assist users in navigating in and around an environment, identifying persons and objects they encounter, and providing feedback to the users about their surroundings and activities. Therefore, there is a need for apparatuses and methods for automatically capturing and processing images and audio to provide useful information to users of the apparatuses, and for systems and methods to process and leverage information gathered by the apparatuses.
Embodiments consistent with the present disclosure provide devices and methods for automatically capturing and processing images and audio from an environment of a user, and systems and methods for processing information related to images and audio captured from the environment of the user.
In an exemplary embodiment, a wearable apparatus may comprise at least one image capture device configured to capture a plurality of images from an environment of the user of the wearable apparatus; at least one audio capture device configured to receive sounds from the environment of the user; and at least one processor. The at least one processor may be configured to receive the plurality of images captured by the image capture device; receive audio signals representative of the sounds received by the audio capture device; analyze the audio signals to identify a descriptor word describing the object; retrieve, from a database, a visual characteristic of the object based on the descriptor word; determine a location of the object based on a representation of the object in at least one of the plurality of images, the representation of the object being identified based on the visual characteristic; determine a location of a hand of the user based on a representation of the hand in at least one of the plurality of images; determine at least a direction between the hand and the object; determine feedback indicative of the direction; and provide the feedback to the user.
In another exemplary embodiment, a method for locating an object for a user is disclosed.
The method may comprise receiving a plurality of images captured by an image capture device from an environment of the user; receiving audio signals representative of sounds received by an audio capture device from the environment of the user; analyzing the audio signals to identify a descriptor word describing the object; retrieving, from a database, a visual characteristic of the object based on the descriptor word; determining a location of the object based on a representation of the object in at least one of the plurality of images, the representation of the object being identified based on the visual characteristic; determining a location of a hand of the user based on a representation of the hand in at least one of the plurality of images; determining at least a direction between the hand and the object; determining feedback indicative of the direction; and providing the feedback to the user.
In another exemplary embodiment, non-transitory computer readable storage media may include instructions that, when executed by at least one processor, cause the at least one processor to perform operations for locating an object for a user. The operations may comprise receiving a plurality of images captured by an image capture device from an environment of the user; receiving audio signals representative of sounds received by an audio capture device from the environment of the user; analyzing the audio signals to identify a descriptor word describing the object; retrieving, from a database, a visual characteristic of the object based on the descriptor word; determining a location of the object based on a representation of the object in at least one of the plurality of images, the representation of the object being identified based on the visual characteristic; determining a location of a hand of the user based on a representation of the hand in at least one of the plurality of images; determining at least a direction between the hand and the object; determining feedback indicative of the direction; and providing the feedback to the user.

In some embodiments, apparatus 110 may communicate wirelessly or via a wire with a computing device 120. In some embodiments, computing device 120 may include, for example, a smartphone, or a tablet, or a dedicated processing unit, which may be portable (e.g., can be carried in a pocket of user 100). Although shown in
According to the disclosed embodiments, apparatus 110 may include an image sensor system 220 for capturing real-time image data of the field-of-view of user 100. In some embodiments, apparatus 110 may also include a processing unit 210 for controlling and performing the disclosed functionality of apparatus 110, such as to control the capture of image data, analyze the image data, and perform an action and/or output a feedback based on a hand-related trigger identified in the image data. According to the disclosed embodiments, a hand-related trigger may include a gesture performed by user 100 involving a portion of a hand of user 100. Further, consistent with some embodiments, a hand-related trigger may include a wrist-related trigger. Additionally, in some embodiments, apparatus 110 may include a feedback outputting unit 230 for producing an output of information to user 100.
As discussed above, apparatus 110 may include an image sensor 220 for capturing image data. The term “image sensor” refers to a device capable of detecting and converting optical signals in the near-infrared, infrared, visible, and ultraviolet spectrums into electrical signals. The electrical signals may be used to form an image or a video stream (i.e. image data) based on the detected signal. The term “image data” includes any form of data retrieved from optical signals in the near-infrared, infrared, visible, and ultraviolet spectrums. Examples of image sensors may include semiconductor charge-coupled devices (CCD), active pixel sensors in complementary metal-oxide-semiconductor (CMOS), or N-type metal-oxide-semiconductor (NMOS, Live MOS). In some cases, image sensor 220 may be part of a camera included in apparatus 110.
Apparatus 110 may also include a processor 210 for controlling image sensor 220 to capture image data and for analyzing the image data according to the disclosed embodiments. As discussed in further detail below with respect to
In some embodiments, the information or feedback information provided to user 100 may include time information. The time information may include any information related to a current time of day and, as described further below, may be presented in any sensory perceptive manner. In some embodiments, time information may include a current time of day in a preconfigured format (e.g., 2:30 pm or 14:30). Time information may include the time in the user's current time zone (e.g., based on a determined location of user 100), as well as an indication of the time zone and/or a time of day in another desired location. In some embodiments, time information may include a number of hours or minutes relative to one or more predetermined times of day. For example, in some embodiments, time information may include an indication that three hours and fifteen minutes remain until a particular hour (e.g., until 6:00 pm), or some other predetermined time. Time information may also include a duration of time passed since the beginning of a particular activity, such as the start of a meeting or the start of a jog, or any other activity. In some embodiments, the activity may be determined based on analyzed image data. In other embodiments, time information may also include additional information related to a current time and one or more other routine, periodic, or scheduled events. For example, time information may include an indication of the number of minutes remaining until the next scheduled event, as may be determined from a calendar function or other information retrieved from computing device 120 or server 250, as discussed in further detail below.
Feedback outputting unit 230 may include one or more feedback systems for providing the output of information to user 100. In the disclosed embodiments, the audible or visual feedback may be provided via any type of connected audible or visual system or both. Feedback of information according to the disclosed embodiments may include audible feedback to user 100 (e.g., using a Bluetooth™ or other wired or wirelessly connected speaker, or a bone conduction headphone). Feedback outputting unit 230 of some embodiments may additionally or alternatively produce a visible output of information to user 100, for example, as part of an augmented reality display projected onto a lens of glasses 130 or provided via a separate heads up display in communication with apparatus 110, such as a display 260 provided as part of computing device 120, which may include an onboard automobile heads up display, an augmented reality device, a virtual reality device, a smartphone, PC, table, etc.
The term “computing device” refers to a device including a processing unit and having computing capabilities. Some examples of computing device 120 include a PC, laptop, tablet, or other computing systems such as an on-board computing system of an automobile, for example, each configured to communicate directly with apparatus 110 or server 250 over network 240. Another example of computing device 120 includes a smartphone having a display 260. In some embodiments, computing device 120 may be a computing system configured particularly for apparatus 110, and may be provided integral to apparatus 110 or tethered thereto. Apparatus 110 can also connect to computing device 120 over network 240 via any known wireless standard (e.g., Wi-Fi, Bluetooth®, etc.), as well as near-filed capacitive coupling, and other short range wireless techniques, or via a wired connection. In an embodiment in which computing device 120 is a smartphone, computing device 120 may have a dedicated application installed therein. For example, user 100 may view on display 260 data (e.g., images, video clips, extracted information, feedback information, etc.) that originate from or are triggered by apparatus 110. In addition, user 100 may select part of the data for storage in server 250.
Network 240 may be a shared, public, or private network, may encompass a wide area or local area, and may be implemented through any suitable combination of wired and/or wireless communication networks. Network 240 may further comprise an intranet or the Internet. In some embodiments, network 240 may include short range or near-field wireless communication systems for enabling communication between apparatus 110 and computing device 120 provided in close proximity to each other, such as on or near a user's person, for example. Apparatus 110 may establish a connection to network 240 autonomously, for example, using a wireless module (e.g., Wi-Fi, cellular). In some embodiments, apparatus 110 may use the wireless module when being connected to an external power source, to prolong battery life. Further, communication between apparatus 110 and server 250 may be accomplished through any suitable communication channels, such as, for example, a telephone network, an extranet, an intranet, the Internet, satellite communications, off-line communications, wireless communications, transponder communications, a local area network (LAN), a wide area network (WAN), and a virtual private network (VPN).
As shown in
An example of wearable apparatus 110 incorporated with glasses 130 according to some embodiments (as discussed in connection with
In some embodiments, support 310 may include a quick release mechanism for disengaging and reengaging apparatus 110. For example, support 310 and apparatus 110 may include magnetic elements. As an alternative example, support 310 may include a male latch member and apparatus 110 may include a female receptacle. In other embodiments, support 310 can be an integral part of a pair of glasses, or sold separately and installed by an optometrist. For example, support 310 may be configured for mounting on the arms of glasses 130 near the frame front, but before the hinge. Alternatively, support 310 may be configured for mounting on the bridge of glasses 130.
In some embodiments, apparatus 110 may be provided as part of a glasses frame 130, with or without lenses. Additionally, in some embodiments, apparatus 110 may be configured to provide an augmented reality display projected onto a lens of glasses 130 (if provided), or alternatively, may include a display for projecting time information, for example, according to the disclosed embodiments. Apparatus 110 may include the additional display or alternatively, may be in communication with a separately provided display system that may or may not be attached to glasses 130.
In some embodiments, apparatus 110 may be implemented in a form other than wearable glasses, as described above with respect to
In some embodiments, apparatus 110 includes a function button 430 for enabling user 100 to provide input to apparatus 110. Function button 430 may accept different types of tactile input (e.g., a tap, a click, a double-click, a long press, a right-to-left slide, a left-to-right slide). In some embodiments, each type of input may be associated with a different action. For example, a tap may be associated with the function of taking a picture, while a right-to-left slide may be associated with the function of recording a video.
Apparatus 110 may be attached to an article of clothing (e.g., a shirt, a belt, pants, etc.), of user 100 at an edge of the clothing using a clip 431 as shown in
An example embodiment of apparatus 110 is shown in
Various views of apparatus 110 are illustrated in
The example embodiments discussed above with respect to
Processor 210, depicted in
Although, in the embodiment illustrated in
In some embodiments, processor 210 may process a plurality of images captured from the environment of user 100 to determine different parameters related to capturing subsequent images. For example, processor 210 can determine, based on information derived from captured image data, a value for at least one of the following: an image resolution, a compression ratio, a cropping parameter, frame rate, a focus point, an exposure time, an aperture size, and a light sensitivity. The determined value may be used in capturing at least one subsequent image. Additionally, processor 210 can detect images including at least one hand-related trigger in the environment of the user and perform an action and/or provide an output of information to a user via feedback outputting unit 230.
In another embodiment, processor 210 can change the aiming direction of image sensor 220. For example, when apparatus 110 is attached with clip 420, the aiming direction of image sensor 220 may not coincide with the field-of-view of user 100. Processor 210 may recognize certain situations from the analyzed image data and adjust the aiming direction of image sensor 220 to capture relevant image data. For example, in one embodiment, processor 210 may detect an interaction with another individual and sense that the individual is not fully in view, because image sensor 220 is tilted down. Responsive thereto, processor 210 may adjust the aiming direction of image sensor 220 to capture image data of the individual. Other scenarios are also contemplated where processor 210 may recognize the need to adjust an aiming direction of image sensor 220.
In some embodiments, processor 210 may communicate data to feedback-outputting unit 230, which may include any device configured to provide information to a user 100. Feedback outputting unit 230 may be provided as part of apparatus 110 (as shown) or may be provided external to apparatus 110 and communicatively coupled thereto. Feedback-outputting unit 230 may be configured to output visual or nonvisual feedback based on signals received from processor 210, such as when processor 210 recognizes a hand-related trigger in the analyzed image data.
The term “feedback” refers to any output or information provided in response to processing at least one image in an environment. In some embodiments, as similarly described above, feedback may include an audible or visible indication of time information, detected text or numerals, the value of currency, a branded product, a person's identity, the identity of a landmark or other environmental situation or condition including the street names at an intersection or the color of a traffic light, etc., as well as other information associated with each of these. For example, in some embodiments, feedback may include additional information regarding the amount of currency still needed to complete a transaction, information regarding the identified person, historical information or times and prices of admission etc. of a detected landmark etc. In some embodiments, feedback may include an audible tone, a tactile response, and/or information previously recorded by user 100. Feedback-outputting unit 230 may comprise appropriate components for outputting acoustical and tactile feedback. For example, feedback-outputting unit 230 may comprise audio headphones, a hearing aid type device, a speaker, a bone conduction headphone, interfaces that provide tactile cues, vibrotactile stimulators, etc. In some embodiments, processor 210 may communicate signals with an external feedback outputting unit 230 via a wireless transceiver 530, a wired connection, or some other communication interface. In some embodiments, feedback outputting unit 230 may also include any suitable display device for visually displaying information to user 100.
As shown in
As further shown in
Mobile power source 520 may power one or more wireless transceivers (e.g., wireless transceiver 530 in
Apparatus 110 may operate in a first processing-mode and in a second processing-mode, such that the first processing-mode may consume less power than the second processing-mode. For example, in the first processing-mode, apparatus 110 may capture images and process the captured images to make real-time decisions based on an identifying hand-related trigger, for example. In the second processing-mode, apparatus 110 may extract information from stored images in memory 550 and delete images from memory 550. In some embodiments, mobile power source 520 may provide more than fifteen hours of processing in the first processing-mode and about three hours of processing in the second processing-mode. Accordingly, different processing-modes may allow mobile power source 520 to produce sufficient power for powering apparatus 110 for various time periods (e.g., more than two hours, more than four hours, more than ten hours, etc.).
In some embodiments, apparatus 110 may use first processor 210a in the first processing-mode when powered by mobile power source 520, and second processor 210b in the second processing-mode when powered by external power source 580 that is connectable via power connector 510. In other embodiments, apparatus 110 may determine, based on predefined conditions, which processors or which processing modes to use. Apparatus 110 may operate in the second processing-mode even when apparatus 110 is not powered by external power source 580. For example, apparatus 110 may determine that it should operate in the second processing-mode when apparatus 110 is not powered by external power source 580, if the available storage space in memory 550 for storing new image data is lower than a predefined threshold.
Although one wireless transceiver is depicted in
In some embodiments, processor 210 and processor 540 are configured to extract information from captured image data. The term “extracting information” includes any process by which information associated with objects, individuals, locations, events, etc., is identified in the captured image data by any means known to those of ordinary skill in the art. In some embodiments, apparatus 110 may use the extracted information to send feedback or other real-time indications to feedback outputting unit 230 or to computing device 120. In some embodiments, processor 210 may identify in the image data the individual standing in front of user 100, and send computing device 120 the name of the individual and the last time user 100 met the individual. In another embodiment, processor 210 may identify in the image data, one or more visible triggers, including a hand-related trigger, and determine whether the trigger is associated with a person other than the user of the wearable apparatus to selectively determine whether to perform an action associated with the trigger. One such action may be to provide a feedback to user 100 via feedback-outputting unit 230 provided as part of (or in communication with) apparatus 110 or via a feedback unit 545 provided as part of computing device 120. For example, feedback-outputting unit 545 may be in communication with display 260 to cause the display 260 to visibly output information. In some embodiments, processor 210 may identify in the image data a hand-related trigger and send computing device 120 an indication of the trigger. Processor 540 may then process the received trigger information and provide an output via feedback outputting unit 545 or display 260 based on the hand-related trigger. In other embodiments, processor 540 may determine a hand-related trigger and provide suitable feedback similar to the above, based on image data received from apparatus 110. In some embodiments, processor 540 may provide instructions or other information, such as environmental information to apparatus 110 based on an identified hand-related trigger.
In some embodiments, processor 210 may identify other environmental information in the analyzed images, such as an individual standing in front user 100, and send computing device 120 information related to the analyzed information such as the name of the individual and the last time user 100 met the individual. In a different embodiment, processor 540 may extract statistical information from captured image data and forward the statistical information to server 250. For example, certain information regarding the types of items a user purchases, or the frequency a user patronizes a particular merchant, etc. may be determined by processor 540. Based on this information, server 250 may send computing device 120 coupons and discounts associated with the user's preferences.
When apparatus 110 is connected or wirelessly connected to computing device 120, apparatus 110 may transmit at least part of the image data stored in memory 550a for storage in memory 550b. In some embodiments, after computing device 120 confirms that transferring the part of image data was successful, processor 540 may delete the part of the image data. The term “delete” means that the image is marked as ‘deleted’ and other image data may be stored instead of it, but does not necessarily mean that the image data was physically removed from the memory.
As will be appreciated by a person skilled in the art having the benefit of this disclosure, numerous variations and/or modifications may be made to the disclosed embodiments. Not all components are essential for the operation of apparatus 110. Any component may be located in any appropriate apparatus and the components may be rearranged into a variety of configurations while providing the functionality of the disclosed embodiments. For example, in some embodiments, apparatus 110 may include a camera, a processor, and a wireless transceiver for sending data to another device. Therefore, the foregoing configurations are examples and, regardless of the configurations discussed above, apparatus 110 can capture, store, and/or process images.
Further, the foregoing and following description refers to storing and/or processing images or image data. In the embodiments disclosed herein, the stored and/or processed images or image data may comprise a representation of one or more images captured by image sensor 220. As the term is used herein, a “representation” of an image (or image data) may include an entire image or a portion of an image. A representation of an image (or image data) may have the same resolution or a lower resolution as the image (or image data), and/or a representation of an image (or image data) may be altered in some respect (e.g., be compressed, have a lower resolution, have one or more colors that are altered, etc.).
For example, apparatus 110 may capture an image and store a representation of the image that is compressed as a .JPG file. As another example, apparatus 110 may capture an image in color, but store a black-and-white representation of the color image. As yet another example, apparatus 110 may capture an image and store a different representation of the image (e.g., a portion of the image). For example, apparatus 110 may store a portion of an image that includes a face of a person who appears in the image, but that does not substantially include the environment surrounding the person. Similarly, apparatus 110 may, for example, store a portion of an image that includes a product that appears in the image, but does not substantially include the environment surrounding the product. As yet another example, apparatus 110 may store a representation of an image at a reduced resolution (i.e., at a resolution that is of a lower value than that of the captured image). Storing representations of images may allow apparatus 110 to save storage space in memory 550. Furthermore, processing representations of images may allow apparatus 110 to improve processing efficiency and/or help to preserve battery life.
In addition to the above, in some embodiments, any one of apparatus 110 or computing device 120, via processor 210 or 540, may further process the captured image data to provide additional functionality to recognize objects and/or gestures and/or other information in the captured image data. In some embodiments, actions may be taken based on the identified objects, gestures, or other information. In some embodiments, processor 210 or 540 may identify in the image data, one or more visible triggers, including a hand-related trigger, and determine whether the trigger is associated with a person other than the user to determine whether to perform an action associated with the trigger.
Some embodiments of the present disclosure may include an apparatus securable to an article of clothing of a user. Such an apparatus may include two portions, connectable by a connector. A capturing unit may be designed to be worn on the outside of a user's clothing, and may include an image sensor for capturing images of a user's environment. The capturing unit may be connected to or connectable to a power unit, which may be configured to house a power source and a processing device. The capturing unit may be a small device including a camera or other device for capturing images. The capturing unit may be designed to be inconspicuous and unobtrusive, and may be configured to communicate with a power unit concealed by a user's clothing. The power unit may include bulkier aspects of the system, such as transceiver antennas, at least one battery, a processing device, etc. In some embodiments, communication between the capturing unit and the power unit may be provided by a data cable included in the connector, while in other embodiments, communication may be wirelessly achieved between the capturing unit and the power unit. Some embodiments may permit alteration of the orientation of an image sensor of the capture unit, for example to better capture images of interest.
Image sensor 220 may be configured to be movable with the head of user 100 in such a manner that an aiming direction of image sensor 220 substantially coincides with a field of view of user 100. For example, as described above, a camera associated with image sensor 220 may be installed within capturing unit 710 at a predetermined angle in a position facing slightly upwards or downwards, depending on an intended location of capturing unit 710. Accordingly, the set aiming direction of image sensor 220 may match the field-of-view of user 100. In some embodiments, processor 210 may change the orientation of image sensor 220 using image data provided from image sensor 220. For example, processor 210 may recognize that a user is reading a book and determine that the aiming direction of image sensor 220 is offset from the text. That is, because the words in the beginning of each line of text are not fully in view, processor 210 may determine that image sensor 220 is tilted in the wrong direction. Responsive thereto, processor 210 may adjust the aiming direction of image sensor 220.
Orientation identification module 601 may be configured to identify an orientation of an image sensor 220 of capturing unit 710. An orientation of an image sensor 220 may be identified, for example, by analysis of images captured by image sensor 220 of capturing unit 710, by tilt or attitude sensing devices within capturing unit 710, and by measuring a relative direction of orientation adjustment unit 705 with respect to the remainder of capturing unit 710.
Orientation adjustment module 602 may be configured to adjust an orientation of image sensor 220 of capturing unit 710. As discussed above, image sensor 220 may be mounted on an orientation adjustment unit 705 configured for movement. Orientation adjustment unit 705 may be configured for rotational and/or lateral movement in response to commands from orientation adjustment module 602. In some embodiments orientation adjustment unit 705 may be adjust an orientation of image sensor 220 via motors, electromagnets, permanent magnets, and/or any suitable combination thereof.
In some embodiments, monitoring module 603 may be provided for continuous monitoring. Such continuous monitoring may include tracking a movement of at least a portion of an object included in one or more images captured by the image sensor. For example, in one embodiment, apparatus 110 may track an object as long as the object remains substantially within the field-of-view of image sensor 220. In additional embodiments, monitoring module 603 may engage orientation adjustment module 602 to instruct orientation adjustment unit 705 to continually orient image sensor 220 towards an object of interest. For example, in one embodiment, monitoring module 603 may cause image sensor 220 to adjust an orientation to ensure that a certain designated object, for example, the face of a particular person, remains within the field-of view of image sensor 220, even as that designated object moves about. In another embodiment, monitoring module 603 may continuously monitor an area of interest included in one or more images captured by the image sensor. For example, a user may be occupied by a certain task, for example, typing on a laptop, while image sensor 220 remains oriented in a particular direction and continuously monitors a portion of each image from a series of images to detect a trigger or other event. For example, image sensor 210 may be oriented towards a piece of laboratory equipment and monitoring module 603 may be configured to monitor a status light on the laboratory equipment for a change in status, while the user's attention is otherwise occupied.
In some embodiments consistent with the present disclosure, capturing unit 710 may include a plurality of image sensors 220. The plurality of image sensors 220 may each be configured to capture different image data. For example, when a plurality of image sensors 220 are provided, the image sensors 220 may capture images having different resolutions, may capture wider or narrower fields of view, and may have different levels of magnification. Image sensors 220 may be provided with varying lenses to permit these different configurations. In some embodiments, a plurality of image sensors 220 may include image sensors 220 having different orientations. Thus, each of the plurality of image sensors 220 may be pointed in a different direction to capture different images. The fields of view of image sensors 220 may be overlapping in some embodiments. The plurality of image sensors 220 may each be configured for orientation adjustment, for example, by being paired with an image adjustment unit 705. In some embodiments, monitoring module 603, or another module associated with memory 550, may be configured to individually adjust the orientations of the plurality of image sensors 220 as well as to turn each of the plurality of image sensors 220 on or off as may be required. In some embodiments, monitoring an object or person captured by an image sensor 220 may include tracking movement of the object across the fields of view of the plurality of image sensors 220.
Embodiments consistent with the present disclosure may include connectors configured to connect a capturing unit and a power unit of a wearable apparatus. Capturing units consistent with the present disclosure may include least one image sensor configured to capture images of an environment of a user. Power units consistent with the present disclosure may be configured to house a power source and/or at least one processing device. Connectors consistent with the present disclosure may be configured to connect the capturing unit and the power unit, and may be configured to secure the apparatus to an article of clothing such that the capturing unit is positioned over an outer surface of the article of clothing and the power unit is positioned under an inner surface of the article of clothing Exemplary embodiments of capturing units, connectors, and power units consistent with the disclosure are discussed in further detail with respect to
Capturing unit 710 may include an image sensor 220 and an orientation adjustment unit 705 (as illustrated in
Connector 730 may include a clip 715 or other mechanical connection designed to clip or attach capturing unit 710 and power unit 720 to an article of clothing 750 as illustrated in

In further embodiments, an apparatus securable to an article of clothing may further include protective circuitry associated with power source 520 housed in in power unit 720.
Protective circuitry 775 may be configured to protect image sensor 220 and/or other elements of capturing unit 710 from potentially dangerous currents and/or voltages produced by mobile power source 520. Protective circuitry 775 may include passive components such as capacitors, resistors, diodes, inductors, etc., to provide protection to elements of capturing unit 710. In some embodiments, protective circuitry 775 may also include active components, such as transistors, to provide protection to elements of capturing unit 710. For example, in some embodiments, protective circuitry 775 may comprise one or more resistors serving as fuses. Each fuse may comprise a wire or strip that melts (thereby braking a connection between circuitry of image capturing unit 710 and circuitry of power unit 720) when current flowing through the fuse exceeds a predetermined limit (e.g., 500 milliamps, 900 milliamps, 1 amp, 1.1 amps, 2 amp, 2.1 amps, 3 amps, etc.) Any or all of the previously described embodiments may incorporate protective circuitry 775.
In some embodiments, the wearable apparatus may transmit data to a computing device (e.g., a smartphone, tablet, watch, computer, etc.) over one or more networks via any known wireless standard (e.g., cellular, Wi-Fi, Bluetooth®, etc.), or via near-filed capacitive coupling, other short range wireless techniques, or via a wired connection. Similarly, the wearable apparatus may receive data from the computing device over one or more networks via any known wireless standard (e.g., cellular, Wi-Fi, Bluetooth®, etc.), or via near-filed capacitive coupling, other short range wireless techniques, or via a wired connection. The data transmitted to the wearable apparatus and/or received by the wireless apparatus may include images, portions of images, identifiers related to information appearing in analyzed images or associated with analyzed audio, or any other data representing image and/or audio data. For example, an image may be analyzed and an identifier related to an activity occurring in the image may be transmitted to the computing device (e.g., the “paired device”). In the embodiments described herein, the wearable apparatus may process images and/or audio locally (on board the wearable apparatus) and/or remotely (via a computing device). Further, in the embodiments described herein, the wearable apparatus may transmit data related to the analysis of images and/or audio to a computing device for further analysis, display, and/or transmission to another device (e.g., a paired device). Further, a paired device may execute one or more applications (apps) to process, display, and/or analyze data (e.g., identifiers, text, images, audio, etc.) received from the wearable apparatus.

Further, the at least one keyword may be determined based on the recognized person, object, location, scene, etc. For example, the at least one keyword may comprise: a person's name, an object's name, a place's name, a date, a sport team's name, a movie's name, a book's name, and so forth.
In some embodiments, at least one keyword may be determined based on the user's behavior. The user's behavior may be determined based on an analysis of the one or more images captured by image sensor 220. In some embodiments, at least one keyword may be determined based on activities of a user and/or other person. The one or more images captured by image sensor 220 may be analyzed to identify the activities of the user and/or the other person who appears in one or more images captured by image sensor 220. In some embodiments, at least one keyword may be determined based on at least one or more audio segments captured by apparatus 110. In some embodiments, at least one keyword may be determined based on at least GPS information associated with the user. In some embodiments, at least one keyword may be determined based on at least the current time and/or date.
In some embodiments, at least one search query may be determined based on at least one keyword. In some cases, the at least one search query may comprise the at least one keyword. In some cases, the at least one search query may comprise the at least one keyword and additional keywords provided by the user.

In some cases, the at least one search query may comprise the at least one keyword and one or more audio segments, such as audio segments captured by apparatus 110.
In some embodiments, the at least one search query may be transmitted to a search engine. In some embodiments, search results provided by the search engine in response to the at least one search query may be provided to the user. In some embodiments, the at least one search query may be used to access a database.
For example, in one embodiment, the keywords may include a name of a type of food, such as quinoa, or a brand name of a food product; and the search will output information related to desirable quantities of consumption, facts about the nutritional profile, and so forth. In another example, in one embodiment, the keywords may include a name of a restaurant, and the search will output information related to the restaurant, such as a menu, opening hours, reviews, and so forth. The name of the restaurant may be obtained using OCR on an image of signage, using GPS information, and so forth. In another example, in one embodiment, the keywords may include a name of a person, and the search will provide information from a social network profile of the person. The name of the person may be obtained using OCR on an image of a name tag attached to the person's shirt, using face recognition algorithms, and so forth. In another example, in one embodiment, the keywords may include a name of a book, and the search will output information related to the book, such as reviews, sales statistics, information regarding the author of the book, and so forth. In another example, in one embodiment, the keywords may include a name of a movie, and the search will output information related to the movie, such as reviews, box office statistics, information regarding the cast of the movie, show times, and so forth. In another example, in one embodiment, the keywords may include a name of a sport team, and the search will output information related to the sport team, such as statistics, latest results, future schedule, information regarding the players of the sport team, and so forth. For example, the name of the sports team may be obtained using audio recognition algorithms.
In some embodiments, the wearable apparatus described above may be used to locate objects within a field of view of a user. For example, a user of the device may request instructions to “find my keys” or ask “where's my phone?”. Based on these or similar commands, the device may provide feedback to the user, for example, through audio commands, to help the user locate the object. Such feedback may be useful in a variety of situations. For example, the system may be useful to visually impaired users, who are unable to see the object clearly for themselves. The disclosed device may be equally useful to users without an impairment as well. For example, the camera of the wearable device may be an infrared camera, or other type of camera that may detect different wavelengths of light than the user's eyes. Accordingly, in low-light situations or other conditions, the camera may be more apt to detect the object than the user. As another example, when the object is placed in a cluttered environment, the device may be able to locate the object quicker than the user. Further, in some instances, the user may not know what the object looks like but may know the name of the object. For example, if the user is working on a vehicle, he or she may wish to locate the engine speed sensor, but may not know where it is or what it looks like. Accordingly, the system may help the user find the sensor when working on the vehicle. Thus, the disclosed embodiments may provide, among other advantages, improved efficiency, convenience, and functionality over prior art devices.
In some embodiments, apparatus 110 may be configured to receive and process audio information. For example, apparatus 110 may detect and capture sounds in the environment of the user via one or more microphones. Apparatus 110 may use this audio information to recognize words spoken by the user, which may include commands to find certain objects.
Processor 210 may be configured to perform a series of operations in accordance with the disclosed methods based on instructions stored in memory.
Image analysis component 1804 may store instructions and data for performing tasks associated with analyzing images captured by wearable apparatus 110. For example, image analysis component 1804 may include one or more image detection algorithms and associated parameters for recognizing objects in images. For example, this may include image detection or processing algorithms such as convolutional neural networks (CNN), scale-invariant feature transform (SIFT), histogram of oriented gradients (HOG) features, or other techniques. Image analysis component 1804 may include instructions for detecting objects queried by a user, a hand of the user, and/or other objects that may be relevant to locating an object for a user.
Audio analysis component 1808 may store instructions and data for performing tasks associated with analyzing audio signals captured by wearable apparatus 110 or associated devices. For example, audio sensor 1710 may capture one or more audio signals from the environment of the user and processor 210 may analyze them using instructions stored in audio analysis component 1808. In some embodiments, audio analysis component 1808 may include one or more audio processing algorithms and associated parameters. For example, audio analysis may include speech recognition algorithms, such as automatic speech recognition (ASR) algorithms, Hidden Markov models, Dynamic time warping (DTW)-based speech recognition, natural language processing, or similar algorithms. In some embodiments, audio analysis component 1808 may be configured to recognize particular users, for example, by identifying voiceprints or other vocal signatures of a user.
Characteristics retrieval component 1812 may include instructions for retrieving visual characteristics of objects. For example, characteristics retrieval component 1812 may include instructions for accessing a database of visual characteristics associated with objects and comparing object descriptor words to the database to retrieve the visual characteristics. The database may be stored in any suitable storage location, including memory 550, a separate memory in wearable apparatus 100, a memory of an external device, a cloud-based storage platform, a remote server, or the like. As used herein, a visual characteristic may include any property of an object that may be observed or searched for in an image. For example, a visual characteristic may include a size, shape, color, texture, reflectivity, luminosity, or similar characteristics. In some embodiments, each of the characteristics may be stored with an associated probability. For example, if the queried object is an eraser, there may be a relatively high probability that the color is pink or white, and lower probabilities for other possible colors. In some embodiments, the visual characteristics may include one or more images of the object. These may include generic or stock images of objects, previous images captured by the wearable apparatus, user-captured images (e.g., through computing device 120), or various other types of images. Additional details regarding the retrieval of visual characteristics are provided below.
Spatial calculation component 1816 may include instructions for determining spatial relationships between objects detected in the environment of the user by the wearable apparatus. For example, this may include determining a distance and/or direction to an object relative to another object, such as the hand of a user. Accordingly, spatial calculation component 1816 may include one or more algorithms for determining three-dimensional positions of objects, including edge detection, corner detection, blob detection, ridge detection, and/or scale space algorithms. The direction may be determined along one axis at a time, such that usually up to three different sequences of commands may need to be provided to the user. In some embodiments, more than three different sequences of commands may be needed, for example, if the full required motion in one axis cannot be completed because an object is blocking it such that a movement may need to occur in a second dimension before a movement in the first dimension may be completed.
Feedback component 1820 may be configured to determine and provide feedback to a user. For example, the feedback may include instructions for the user to move his or her hand to reach a queried object. Feedback may be provided in a variety of ways. In some embodiments the feedback may be audio feedback. For example, the feedback may be instructions to move a hand in a specified direction and optionally in a specified distance (e.g., “up,” “forward 6 inches,” “left 20 centimeters,” or the like). The direction in which the hand is to be moved may be provided one axis at a time. For example, if the output is to be provided as audio, the words “up,” “right” or the like may be played. Alternatively, word combinations may be played, for example “right-up,” or the like. The audio feedback may also indicate the calculated distance, such that a greater sense of urgency is provided when the hand is closer to the object, for example higher volume, higher pitch, more frequent sounds, or the like. In some embodiments, haptic feedback may be provided. For example, wearable apparatus 110 may be configured to vibrate to indicate the distance and/or direction to an object. For example, a predetermined frequency may be used for each direction, where the distance may be expressed by the motion amplitude, such that more intense vibrations are provided as the distance to the object is reduced. As another example, the device may vibrate in a predetermined sequence of directions (e.g., left/right-up/down-forward/back) and the frequency may indicate which direction to move (e.g., up vs. down), where the amplitude indicates the distance. Various other schemes may be used for providing haptic feedback to represent a distance and direction, as described further below with respect to
In some embodiments, feedback component 1820 may include instructions for providing the feedback to an output unit. For example, feedback component 1820 may provide the feedback for output to a speaker of wearable apparatus 110, a speaker of computing device 120, or any other audio device in communication with wearable apparatus 110. Alternatively, feedback component 1820 may provide the feedback for output to a vibration motor of wearable apparatus 110, a vibration motor of computing device 120, or any other vibration device in communication with wearable apparatus 110. The feedback may be transmitted directly for output or stored in a memory for later output, or a combination thereof. As another example, the feedback may be transmitted directly to an outputting unit, such as feedback outputting unit 230 or 545. The feedback may be output by any means disclosed herein. While described as a single component for simplicity, it is to be understood that the feedback component may include separate feedback determination and feedback output components.
Wearable apparatus 110 may be configured to process audio signals in connection with processing image 1900. For example, a user may issue a command to find coffee cup 1910. The command may be presented in various ways. In some embodiments, wearable apparatus 110 may search for and identify descriptor words within audio signals captured by audio sensor 1710. These descriptor words may be compared to a database to identify visual characteristics associated with the object. In the example shown in image 1900, the descriptor word may be “coffee cup.” In some embodiments, wearable apparatus 110 may use one or more natural language processing algorithms to identify the descriptor word. For example, the user may use various other words to describe coffee cup 1910, such as “mug,” “my coffee,” “the cup,” “cappuccino,” “hot chocolate” or other similar words. Wearable apparatus 110 may associate these words with the term “coffee cup” prior to searching the database, which may reduce the number of descriptor words that must be stored. Alternatively or additionally, the database may associate multiple descriptor words with each object.
Based on the identified descriptor word, wearable apparatus 110 may search a database for objects that match the identified descriptor word to identify visual characteristics of the coffee cup. For example, these visual characteristics may include data defining a shape, size, color, or texture of the coffee cup, words or images expected to be found on the coffee cup, or other visual characteristics. In some embodiments, the visual characteristics may include an image of a coffee cup. For example, this may include a generic image of a coffee cup (e.g., a stock photo, a pre-stored system photo, etc.). In some embodiments, wearable apparatus 110 may be configured to search the internet, a separate image database, or other sources to retrieve a generic image of a coffee cup, which may then be stored for future analysis. In some embodiments, the image may be an image previously captured by wearable apparatus 110 or another device, such as computing device 120. For example, wearable apparatus 110 may capture an image of coffee cup 1930 and may store it for future analysis. In some embodiments, a user may be able to associate the image with the descriptor word. For example, the user may point image sensor 220 at coffee cup 1910 and say “this is the coffee cup” which may prompt wearable apparatus to store the image for future use. As another example, the user may capture an image of coffee cup 1910 using computing device 120 and may enter text or voice recordings identifying the object as the coffee cup.
In some embodiments, detection of one or more objects may occur prior to identifying the descriptor word. For example, wearable apparatus 110 may detect representations of objects in the captured image and may compare these representations to the visual characteristic database. Accordingly, the system may automatically associate descriptors with objects in the environment. Then, when the user queries an object using the descriptor word, the object may already have been identified in the images.
According to some embodiments, the user may provide an input triggering detection of the descriptor word. For example, the user may say “find the coffee cup,” “please find my glasses,” or “where are my keys.” The system may recognize “find,” “please find,” or “where are” as instruction words triggering detection of the descriptor word. The system may use word spotting or other speech recognition tools to detect the instruction words. In some embodiments, the descriptor word may be identified based on its proximity within the audio signal to the instruction word. For example, the system may look for a descriptor word following (or in some cases, preceding) the instruction word. In some embodiments, the instruction word may be a predefined command or set of commands known by the user. Alternatively or additionally, the system may be configured to recognize commands from the user's natural speech. For example, the instruction word may be determined through natural language processing algorithms, similar to the descriptor word described above. Various other means for triggering detection of the descriptor word may be used. For example, the user may press a button or select an option through a graphical user interface (e.g., on computing device 120) indicating the user will provide the descriptor word.
In some embodiments, the descriptor word may be associated with a modifier, which may be used to identify the correct object in the database. For example, rather than finding a coffee cup in general, the user may specify a particular coffee cup. As other examples, the user may say “find my coffee,” “locate Dave's phone,” “where's the blue marker,” or “help me pick up the convertible keys,” where “my,” “Dave's,” “blue,” and “the convertible” are modifiers specifying a particular object or distinguishing the object from other similar objects. In the example shown in
As described above, the user may provide input defining the particular object. For example, the user may say “this is my phone,” which may associate an image of the user's phone with the user in the database. The system may then store the image in the database for future analysis. Accordingly, the system may recognize “this is,” “save this as,” or similar commands as instruction words for storing visual characteristics. In some embodiments, the system may extract other visual characteristics, such as shape, size, and color, and store this information in the database associated with the particular object.
Based on visual characteristics retrieved using characteristics retrieval component 1812, wearable apparatus 110 may determine a location of coffee cup 1910 and a hand 1920 of the user. This may include comparing the stored visual characteristics to image data, as described above. In some embodiments, the system may be configured to distinguish between multiple possible objects. In the example shown in
Wearable apparatus 110 may then determine distance and/or direction information between the user's hand and the located object. For example, spatial calculation component 1816 may be used to determine direction 1930 (which may also include a distance) between hand 1920 and coffee cup 1910. This distance and direction information may be conveyed to the user to help locate the object, as described further below with respect to
In some embodiments, the distance and direction may be broken into multiple components. For example, direction 1930 may be broken into x, y, and z components, as shown in
Wearable apparatus 110 may then be configured to provide feedback to the user through feedback component 1820.
As another example, audio feedback 2010 may include a tone, a beep, or a series of tones or beeps. For example, as shown in
In some embodiments, wearable apparatus 110 or a separate device (e.g., a hearing aid device, computing device 120, etc.) may present haptic feedback to the user for locating the object. For example, wearable apparatus 110 may present haptic feedback 2020 based on the distance and/or direction from hand 2006 to keys 2004. This may include vibrational feedback, electrical stimulation feedback, ultrasonic feedback, or any other form of tactile feedback. Similar to audio feedback 2010, wearable apparatus 110 may vary one or more properties of the feedback, such as a frequency (F), an amplitude (A), timing between signals, or other variables to convey the distance and/or direction information. For example, the amplitude may indicate a distance to the object, whereas a frequency may indicate a direction to the object (e.g., varying frequency as the user moves his or her hand along an x-y plane, etc.). Various other properties or combinations of properties may be used to convey the information to the user.
In some embodiments, the feedback may be presented to the user in other ways. For example, the feedback may be presented to the user on a display of wearable apparatus 110, computing device 120, or a separate device. This may be useful in embodiments where the user needs help recognizing a particular object, where the user needs help identifying the object in a crowded space with many objects, where the user is farsighted and can see the screen despite not being able to see the object, or various other scenarios. The feedback may be presented in other forms, such as a light or series of lights, or any other means of providing information to the user.
In step 2110, process 2100 may include receiving a plurality of images captured by an image capture device from an environment of the user. For example, this may include receiving image 1900 captured by image sensor 220. As described above, one or more of the images may include representations of objects within the environment of the user.
In step 2120, process 2100 may include receiving audio signals representative of sounds received by an audio capture device from the environment of the user. For example, audio sensor 1710 may capture sounds from the environment of the user and may transmit them to processor 210. This may include voice commands spoken by the user, as described above.
In step 2130, process 2100 may include analyzing the audio signals to identify a descriptor word describing the object. The descriptor word may include any spoken word or group of words describing an object in the environment of the user. In some embodiments, the descriptor word may include a modifier that may further define the object or may identify a particular object, as described in greater detail above. In some embodiments, the descriptor word may be identified based on an instruction word or other input by a user. For example, step 2130 may further include analyzing the audio signal to identify an instruction word, as described above. The instruction word may be any word or group of words indicating the user is looking for an object. For example, the instruction word may be a pre-defined command for locating an object. This may be a default command for wearable apparatus 110, a user-defined command, or the like. In some embodiments, the descriptor word may be identified based on a proximity of the descriptor word to the instruction word. For example, the system may detect the instruction word and may search for the descriptor word as a word following (or preceding) the instruction word. For example, step 2130 may include using a word spotting technique on the audio signals to detect instruction words and the descriptor word may be identified based on detection of the instruction word.
In some embodiments, analyzing the audio signals may comprise identifying an audio signal associated with a voice of the user. For example, this may include detecting voices from the audio signals and isolating them from background noise or other audio signals. In some embodiments, this may include detecting the voice of a particular user. For example, step 2120 may include determining a voiceprint associated with the audio signal and comparing the voiceprint to a stored voiceprint of the user to determine whether the user is speaking. Various other forms of analysis may be performed on the audio signals.
In step 2140, process 2100 may include retrieving, from a database, a visual characteristic of the object based on the descriptor word. The database may be stored locally on wearable apparatus 110 (e.g., in memory 550), in computing device 120, on a remote server, on a cloud-bases platform, or the like. The visual characteristics may include various information associated with the appearance of the object. For example, this may include a size, shape, color, texture, luminosity, reflectivity, or other visual properties of an object. In some embodiments, the visual properties may be represented as an image or series of images. Accordingly, retrieving the visual characteristic may comprise retrieving an image of the object, as described above.
In step 2150, process 2100 may include determining a location of the object based on a representation of the object in at least one of the plurality of images. In some embodiments, the representation of the object may be identified based on the visual characteristic. For example, if the visual characteristic is represented by an image, step 2150 may include comparing the retrieved image to the captured image to detect the representation of the object in the captured image. In some embodiments, step 2150 may include distinguishing between multiple objects represented in the image that may match the descriptor word. This may include determining a confidence level associated with each object in the image and locating the object with the highest associated confidence level. In some embodiments, the objects may be distinguished based on other factors, such as a relative distance to the user, or other factors. In some embodiments, the most recent image or set of images may be used to determine the location of the object. In some embodiments, the object may be detected in earlier images. For example, if the object is not found in the most recent image or images, step 2150 may include searching previous images until the object is found. Accordingly, the previous images may be stored locally on wearable apparatus 110 (e.g., in memory 550, a temporary memory (e.g., RAM)), etc.) or on a separate device (e.g., computing device 120, a remote storage database, a cloud-storage platform, etc.). In some embodiments, a user may provide an input indicating a time or timeframe that the object may be found in the images. For example, the user may say “I put my keys down when I got home at 2 PM,” which may prompt the system to search images with timestamps near 2:00 PM. In some embodiments, a default or user-defined time setpoint may indicate how earlier the system should begin searching.
In step 2160, process 2100 may include determining a location of a hand of the user based on a representation of the hand in at least one of the plurality of images. For example, step 2160 may determine a location of hand 1920 in image 1900. This may include applying one or more feature or object recognition algorithms to locate the hand, as described above.
In step 2170, process 2100 may include determining a direction between the hand and the object. For example, step 2170 may include determining direction 2130 between hand 1920 and coffee cup 1910. In some embodiments, this direction may be represented as a vector in a coordinate system. For example, the direction may be broken into x, y, and z components, as shown in
In step 2190, process 2100 may include providing the feedback to the user. This may include generating a signal based on the determined feedback and transmitting the signal to a feedback device, such as a motor, a speaker, a display, a light, etc. In some embodiments, providing the feedback may comprise presenting audio feedback to the user, as described above. For example, the audio feedback may comprise words describing the direction, and at least one of a volume or a pitch of the audio feedback may indicate a distance between the hand and the object. A higher volume or higher pitch of the audio feedback may indicate a shorter distance, or vice versa. In some embodiments, providing the feedback may comprise providing haptic feedback to the user. For example, the haptic feedback may comprise a vibration and a frequency of the vibration may be indicative of the direction. Similarly, an amplitude of the vibration may be indicative of a distance between the hand and the object. Various other properties or combinations of properties of the haptic or audio feedback may be varied to convey the distance and/or direction information.
