For instance, retail environments may become interactive showrooms or experience centers where the products can be seen, experienced, used and ordered.
U.S. patent application 2012/0067954 A1 discloses a content tagging and management capability for enabling automatic tagging of content and management of tagged content. A sensor is configured for supporting automatic content tagging of content captured by a content capture device (e.g. a smartphone). The sensor may be configured for storing object data associated with an object (e.g. a television), where at least a portion of the object data is stored securely, and for communicating at least a portion of the object data toward the content capture device. The content capture device may comprise a camera. The camera detects the sensors associated with the objects (e.g. the television), receives object data from the sensors and determines the locations of the objects within the captured content. The camera, using the locations of the objects within captured content, associates content tags with the objects within the captured content. The camera, using the object data from sensors, associates information structures with content tags. The information structures securely store information about the model of television, thereby enabling those who later view the picture to access the information of the information structures.
U.S. patent application 2016/0098609 A1 discloses a video analysis device for detecting coded light that illuminates objects, which light comprises a light source identifier. The video analysis device is further configured to detect the objects, by means of, for example, reading a bar code, receiving it via Near Field Communication (NFC), reading QR/AR tags, performing object recognition, or receiving it via human input.
European patent application 0813040 A2 discloses a system for virtually modeling a physical system having immovable and movable objects includes at least two video cameras, each of the video cameras being configured to provide a sequence of images. An image processing system extracts modulated infrared signals from the sequence of images to identify the spatial location of objects using information obtained from both visible light images and infrared images. With this information, a virtual reality modeling system constructs a virtual reality model. Infrared pointers that direct modulated infrared spots having a unique identification against surfaces can be used for surveying, while active or passive infrared tags can track movable objects for virtual reality modeling.
It is an object of the present invention to provide a method for providing product information to a user.
According to a first aspect of the present invention, the object is achieved by a method of providing information about an object, the method comprising:
By determining a position where the virtual representation will be rendered in the image in relation to the object, the object information can be provided accurately at the object feature in the image. This is advantageous, because it enables a user to see which object information is related to which feature of the object. Thus, if the object information is related to a specific part of the object, it is clear to which part the object information relates. Furthermore, if multiple pieces of object information are retrieved based on the code embedded in the light, virtual representations of each of the pieces of object information are rendered at positions that relate to their respective object features.
The light emitted by the light source comprises the code representative of the object information. The (controller of the) light source may be commissioned in advance such that the light source emits light comprising the embedded code that is associated with a respective object. In other words, the association between the object and the light source may be predefined. Alternatively, a detector may detect which object is located at the light source (or which object is illuminated by the light source) in order to determine which code to emit. The object may for example comprise a tag (e.g. an RFID tag, a QR code, an NFC tag, etc.) which may be detected by a tag reader for identifying the object located at or nearby the light source.
The embedded code may comprise an identifier of the object. The identifier may be compared with a plurality of object identifiers stored in a memory in order to retrieve the object information related to the object associated with the identifier. Additionally or alternatively, the embedded code may comprise a link to the object information (e.g. a hyperlink, a URL, etc.) which link may provide information of a storage location of the object information in a memory. Alternatively, the embedded code may comprise the object information about the object.
The step of identifying the object feature of the object in the image may comprise accessing a memory arranged for storing object feature information about at least one object, comparing at least a part of the image with stored object feature information, so as to determine if a similarity criterion has been met between a stored object feature and the at least a part of the image, and identifying, if the similarity criterion has been met, the object feature in the image. By comparing at least a part of the image (comprising an object feature) with the stored object feature information, an object feature and its position in the image can be identified. Any known image analysis technique for recognizing objects and/or object features in an image may be used for identifying the object feature of the object in the image.
Alternatively, the light source may have a predefined position in relation to the object, and the step of capturing the image of the object may comprise capturing an image of the object and the light source, and the step of determining the object feature position of the object feature in the image may comprise determining the object feature position of the object feature in relation to the light source. If the light source has a predefined position in relation to the object (feature), image analysis is not required for determining the position of the object feature, because detecting the position of the light source in the image will be sufficient for determining the position of the object feature in the image. Detecting a position of light sources in an image may require less computing power and/or less complex algorithms than recognizing an object and determining the position of the recognized object.
The method may further comprise the step of receiving a user input via a user interface, which user input may be related to a selection of the virtual representation. This enables a user to provide input about the object feature, request more object information about the object, select an object (feature) in order to add the object to a shopping list, etc. Additionally, the method may further comprise the step of changing the light output of the light source upon receiving the user input command. This is beneficial because it enables a user to see if the user input has been received. The method may further comprise the step of rendering additional information about the object information upon receiving the user input.
The object feature may be related to at least one of: an outline of at least a part of the object, a color of at least a part of the object, an area of least a part of the object, a pattern of at least a part of an object and a marker attached to the object. This may enable further detection of (the position of) the object feature.
The step of determining the position of the virtual representation in the image may further comprise determining the position of the virtual representation such that it is different from the object feature position. As a result, the virtual representation does not overlap the object feature. This is beneficial, because it enables a user to see both the object feature in the image and the virtual representation. This may be further beneficial when multiple pieces of object information related to multiple object features are rendered on the display. Additionally or alternatively, the step of determining the position of the virtual representation in the image may comprise determining the position of the virtual representation such that it is in vicinity of the object feature position. As a result, the virtual representation does not overlap the object feature. This is beneficial, because it enables a user to see the virtual representation next to the object feature in the image. This may be further beneficial when multiple pieces of object information related to multiple object features are rendered on the display, because each rendered object information will be positioned nearby its corresponding object feature.
The step of determining the position of the virtual representation in the image may comprise determining the position of the virtual representation such that it overlaps the object feature position. This is advantageous if the virtual representation is for example used to enhance the object feature in the image (e.g. a green object feature may have a red virtual representation that overlays on top of the green object feature in order to change the color of the object feature).
According to a second aspect of the present invention, the object is achieved by a computer program product for a computing device, the computer program product comprising computer program code to perform any one of the above-mentioned methods when the computer program product is run on a processing unit of the computing device.
According to a third aspect of the present invention, the object is achieved by a mobile device for providing information about an object, the mobile device being arranged for capturing an image of the object and for detecting light emitted by a light source, which light comprises an embedded code representative of object information about the object, the mobile device comprising:
The light source may be comprised in a supporting member arranged for supporting the object. The light source may, for example, be comprised in a shelf arranged for supporting the object. It may be beneficial if the light source is comprised in the supporting member, because it enables a user to capture an image of both the object and the light source at the same time. Alternatively, the light source may be arranged for illuminating the object. The light emitted by the light source and reflected from the object may be detected in order to retrieve the code, and therewith the object information, from the light.
It is beneficial if the object and the light source are in each other's vicinity, or if the light source illuminates the object, because then the relation between the light source and the object is clear.
It should be understood that the claimed mobile device may have similar and/or identical embodiments and advantages as the claimed method.
The above, as well as additional objects, features and advantages of the disclosed systems, mobile devices and methods will be better understood through the following illustrative and non-limiting detailed description of embodiments of devices and methods, with reference to the appended drawings, in which:
All the figures are schematic, not necessarily to scale, and generally only show parts which are necessary in order to elucidate the invention, wherein other parts may be omitted or merely suggested.
The processor (e.g. a microchip, circuitry, a microcontroller, etc.) of the mobile device 102 may be arranged for retrieving the code from the light. The mobile device 102 may comprise a light detector (such as a photodiode) for detecting the code in the light emitted by the light source 110 and a camera (not shown) for capturing the image 104 of the object. Alternatively, the mobile device 102 comprises a camera for capturing the image 104 of the object and for detecting the light emitted by the light source. The camera may, for example, be a rolling shutter camera or a global shutter camera. Techniques for retrieving the code from the light (either by photodiode or by camera) are well known in the art and will not be discussed further.
The processor of the mobile device 102 may be arranged for retrieving the object information. The object information may be retrieved based on the code. The code may comprise, for example, an identifier of the object 120. The processor may be arranged for accessing a (remote) memory, which memory may be arranged for storing associations between object identifiers and object information. The processor may compare the identifier of the object 120 with the stored identifiers, and, if a stored identifier matches the object identifier, determine the object information for the identified object 120. Additionally or alternatively, the code may comprise a link to the object information. The link may, for example, be a URL or a hyperlink which comprises an address that points to a location where the object information is stored. This enables the processor to find the object information of the object 120 based on the link. Additionally or alternatively, the code may comprise the object information. In the latter, the processor may directly retrieve the object information from the code.
The object information may, for example, be price information, material information, size information, stock information, color information, product age information, availability information, user review information, object score information and/or popularity information. The object information may comprise multiple types of object information (e.g. size and price information).
The processor may be further arranged for identifying an object feature 122, 124, 126 of the object 120′ in the image 104. The processor may comprise an image analysis module for identifying the object feature. The object feature 122, 124, 126 may be related to an outline of at least a part of the object 120, a color of at least a part of the object 120, an area of least a part of the object 120, a pattern of at least a part of an object 120 and/or a marker (e.g. a barcode or a QR-code) attached to the object 120. The processor may, for example, identify the object feature 122, 124, 126 of the object 120′ in the image 104 by accessing a memory arranged for storing object feature information about at least one object, comparing at least a part of the image 104 with stored object feature information, so as to determine if a similarity criterion has been met between a stored object feature and the at least a part of the image 104, and identifying, if the similarity criterion has been met, the object feature 122, 124, 126 in the image 104. It should be noted that any image analysis technique for identifying objects and object features from images 104 known in the art may be used for identifying the object feature.
Upon identifying an object feature 122, 124, 126 of the object 120 in the image 104, the processor may determine a position of the object feature (the object feature position) in the image 104. The image analysis module may be arranged for determining this position. The position of the object feature may be an area in the image 104 with specific coordinates in the image. The processor may be arranged for determining a plurality of positions of different object features. Object features may, for example, be part of other object features (e.g. a first object feature may be the outline of the shoe 120, and a second object feature may be the logo 126 on the shoe 120, which is located in the area created by the outline of the shoe). It should be noted that any image analysis technique known in the art may be used for determining a position of an object feature in an image 104.
The processor may be further arranged for generating a virtual representation 132, 134 of the object information. The virtual representation 132, 134 may, for example, be text, a color, a logo, a virtual price tag, a video, an animation, a feedback button, a virtual character (e.g. providing spoken instructions related to the object feature), or an alternative object feature (e.g. showing alternative colors for the object or object part) etc. representative of the object information. The processor may be further arranged for determining a position of the virtual representation 132, 134 in the image 104, wherein the position is related to the (previously determined) object feature position in the image 104. The processor may be arranged for determining the position of the virtual representation 132, 134 such that it is different from the object feature position. The position of the virtual representation may for example be an area in the image 104 with coordinates different from the coordinates of the area of the object feature position. The processor may be arranged for determining the position of the virtual representation 132, 134 such that it is in vicinity of the object feature position. The position of the virtual representation may for example be an area in the image 104 with coordinates nearby the coordinates of the area of the object feature position.
The processor may be arranged for determining a plurality of positions of different object features 122, 124, 126, and the processor may position the virtual representation of an object feature in relation to the position of that object feature and in relation to the other object features. For example, the processor may identify a first object feature (e.g. the outline of the shoe 120′) and a second object feature (e.g. the striped nose 122′ of the shoe 120′) in the image 104 and determine to position the virtual representation 132 of the object information about the object feature 122 outside the outline of the shoe 120′. In this example, the virtual representation 132 is textual information about the object information about the object feature 122, for example information about the pattern on the nose 122 of the shoe 120.
The processor may be arranged for determining the position of the virtual representation 132, 134 such that it overlaps the object feature position. The position of the virtual representation 132, 134 may for example be an area in the image 104 with coordinates similar to the coordinates of the area of the object feature position.
The processor may be further arranged for rendering the image on a display, and for rendering the virtual representation at the position as an overlay on the image. Examples of displays include but are not limited to LED displays, LCD displays and OLED displays. In embodiments, as illustrated in
The mobile device 102 may comprise a camera arranged for capturing a stream of images (a video) of the object 120, and the processor may be arranged for identifying an object feature of the object in the image, for determining an object feature position of the object feature in the image, for generating a virtual representation of the object information, for determining a position of the virtual representation in the image, wherein the position is related to the object feature position in the image, for rendering the image on a display and for rendering the virtual representation at the position as an overlay on the image for each image in the stream of images, or for a selected set of images in the stream of images. The processor may, for example, be arranged for executing the above-mentioned steps once every predetermined time period (e.g. every second) when the stream of images is captured. This may reduce the required computing power for the processor. Capturing a stream of images and rendering the images and the virtual representation over time provides the advantage that the user experiences frequent updates and up-to-date positioning of the virtual representation on top of the captured physical world.
The mobile device 102 may further comprise a user interface for receiving a user input related to a selection of the virtual representation. The user interface may be any type of interface arranged for receiving user input. The user interface may for example comprise a touch-sensitive device such as a touchpad, a touchscreen, one or more buttons and/or one or more sliders for receiving touch input. Additionally or alternatively, the user interface may comprise a microphone arranged for receiving voice commands from the user operating the mobile device. Additionally or alternatively, the user interface may comprise a gesture/motion detection means, such as a gyroscope and/or an accelerometer arranged for detecting gestures made with the mobile device 102, which gestures may be indicative of a selection of a virtual representation. Examples of such gestures are shaking the mobile device 102 or changing the orientation of the mobile device 102. The mobile device 102 may, for example, be smart glasses, and the shaking of a person's head may be the gesture. Additionally or alternatively, the user interface may comprise a camera (e.g. a front facing camera on a smartphone) arranged for detecting user gestures indicative of a selection of a virtual representation. Examples of such gestures are hand movements, eye-blinking, head shaking, etc. Additionally or alternatively, the user interface may comprise a means (e.g. a camera) for gaze detection and selection of a virtual representation may be based on a time period of gazing towards the position of the object. It should be noted that the above-mentioned user interfaces are mere examples of user input elements and illustrate rather than limit the invention, and that those skilled in the art will be able to design many alternative user interfaces without departing from the scope of the appended claims.
Upon receiving the user input, the processor may be arranged for rendering additional information about the object feature on the display. The additional information may, for example, be audio or video content. The additional information may be communicated from a central server (e.g. a server of the store wherein the product is for sale) to the mobile device via a wireless network. This enables a user to request additional information about the object feature. The processor may further be arranged for generating a message upon receiving the user input, which message is related to the object information. The object information may, for example, be related to a size of the shoe, and upon receiving the user input (for example by selecting the virtual representation on a touch screen), a message may be communicated to store personnel to request a different shoe size. The mobile device 102 may further comprise a communication unit for communicating the message, for example to a central server connected to the system 100.
The processor of the mobile device 102 may be further arranged for communicating with a (central) controller, which controller may be connected to the light source. The controller may be arranged for controlling the light output of the light source 110. The controller may be arranged for driving the light source 110 such that it emits light comprising the code. The controller may be further arranged for determining which code is to be emitted by the light source 110. The controller may be further arranged for controlling the color, saturation and/or intensity of the light emitted by the light source 110. The mobile device 102 may be arranged for communicating a message to the controller when the user input has been received. The controller may receive the message from the mobile device 102 and change the light output of the light source 110. The light output may be determined based on a type of user input (e.g. a request for assistance from store personnel may result in a different light output color than a request for additional information about the object 120).
The light source 110 may be any type of light source (e.g. an LED light source, an OLED light source, etc.) for emitting light comprising an embedded code. The system 100 may further comprise a driver (not shown) for driving the light source 100 such that the emitted light comprises the embedded code representative of object information about the object 120. The embedded code may be created by any known principle of embedding a code in light, for example by controlling a time-varying, modulated current to the one or more light sources to produce variations in the light output, by modulating the amplitude of the light, etc.
The light source may be comprised in a supporting member 140 arranged for supporting the object 120. The supporting member 140 may, for example, be a product shelf Alternatively, as illustrated in
Capturing the image 104 of the object 120 may further comprise capturing an image of the object 120 and the light source 110. The light source may have a predefined position in relation to the object 120. In the example of
The system may further comprise a memory for storing object identifiers associated with objects 120. The mobile device 102 may be arranged for detecting light emitted by the light source 110, which light comprises an embedded code representative of an identifier of the object 120. The processor of the mobile device 102 may be arranged for retrieving the code from the light and for retrieving the identifier from the code. The mobile device 102 may further comprise a user interface arranged for receiving user input indicative of a selection of the object 120. The processor may be arranged for storing the identifier of the object 120 in a memory upon receiving the user input. The system may further comprise a controller for changing the color, saturation and/or the intensity of the light emitted by the light source upon receiving the user input. Changing the color, saturation and/or the intensity of the light emitted by the light source 110 provides feedback to the user that the user input has been received. The (new) color, saturation and/or intensity may be based on the type of user input.
The user interface may be any type of user interface arranged for receiving the user input. The user interface may for example comprise a touch-sensitive device 104 such as a touchpad or a touchscreen. Upon detecting the code, and thereby identifying the object 120, the processor may, for example, render a shopping cart icon on the touchscreen. The user may, for example, provide a touch input to select the icon and thereby add the object to the shopping cart, whereupon the mobile device 102 communicates to the control (e.g. via a wireless network) that the object has been added to a list in a memory (in this case to the shopping cart), whereupon the controller may change the light output of the light source 110. Alternatively, the user interface may be arranged for receiving a first swipe gesture in a first direction, whereupon the object 120 may be added to a favorites list, and for receiving a second swipe gesture in a second direction, whereupon the object 120 may be added to a non-favorites list. The controller may be arranged for controlling the light output based on which user input has been received (e.g. turn the light to green or blink the light green when the first swipe gesture has been received and turn the light to red or blink the light red when the second swipe gesture has been received).
Additionally or alternatively, the user interface may comprise a microphone arranged for receiving voice commands from the user operating the mobile device. Example of voice commands may be: “Add this object to my shopping cart”, or “I like this product”, whereupon the processor of the mobile device may store the identifier of the object in a part of the memory based on the user input command.
Additionally or alternatively, the user interface may comprise a gesture/motion detection means, such as a gyroscope and/or an accelerometer arranged for detecting gestures made with the mobile device, which gestures may be indicative adding the object to a list in a memory. Examples of such gestures are shaking the mobile device 102 or changing the orientation of the mobile device 102, which may be indicative of adding the object 120 to a specific list in a memory. The mobile device 102 may, for example, be smart glasses, and the shaking of a person's head may be the gesture (e.g. nodding with the head may be indicative of adding a product to a first list and shaking with the head may be indicative of adding a product to a second list).
Additionally or alternatively, the user interface may comprise a camera (e.g. a front facing camera on a smartphone) arranged for detecting user gestures indicative of adding the object 120 to a specific list in a memory. Examples of such gestures are hand movements, eye-blinking, head shaking, etc.
Additionally or alternatively, the user interface may comprise a means (e.g. a camera) for gaze detection and adding the object 120 to a list or not may be based on a time period of gazing towards the position of the object 120.
It should be noted that the above-mentioned user interfaces are mere examples of user interfaces and illustrate rather than limit the invention, and that those skilled in the art will be able to design many alternative user interfaces without departing from the scope of the appended claims.
The user input may be related to a step in a process, which process comprises a plurality of steps, and the controller may be arranged for changing the color, saturation and/or the intensity of the light based on the step. The process may, for example, be buying one or more objects in a store. The process may comprise a first step of adding one or more objects to a shopping cart, whereupon the controller may change the light output of a respective light source to orange, a second step of placing the order for one or more objects whereupon the controller may change the light output of respective light sources to blue, and a third step of paying for all the objects that are in the shopping cart, whereupon the controller may change the light output of respective light sources to green when payment has been received, or to red when payment has been cancelled.
The controller may be arranged for changing the color, saturation and/or the intensity of the light emitted by the light source back to an original color and/or intensity after a period of time. The controller may, for example, be arranged for blinking the light briefly (e.g. for one second) to indicate that the user input has been received. The controller may be further arranged for changing the color, saturation and/or the intensity of the light emitted by the light source back to an original color and/or intensity when the code is no longer detected. When the user moves away from the object (and also away from the product) and the light (and therewith the code) is no longer detected by the mobile device 102, the light output of the light source 110 may be changed back to an original color and/or intensity. If a new user approaches with a mobile device 102, he or she may add the object 120 to his or her own list, whereupon the light output is changed again accordingly.
The controller may be further arranged for detecting a presence of a mobile device 102 and identifying the mobile device 102. The presence may, for example, be detected when the mobile device has been added to the same network as the controller, or, when a coded light emission of a light source 110 has been received at the mobile device 102, the mobile device 102 may communicate its presence (and an identifier) to the controller. Upon detecting the presence of the mobile device 102, the controller may change the color, saturation and/or the intensity of the light emitted by the light source 110 based on the identification of the mobile device. If, for example, the mobile device 102 has been interacting with an object 120 before, and the object 120 has already been added to a list in a memory, the controller may change the color of the light source associated with that object to a color, saturation and/or brightness that is associated with that list.
The controller may be arranged for changing the color, saturation and/or the intensity of the light emitted by the light source 110 based on predefined light settings, user preferences, user profiles, etc. The controller may, for example, access a user profile associated with the user operating the mobile device 102 in order to retrieve user preference settings related to preferred light settings. A user may provide these preferences, which enables the user to personalize the light feedback that is provided upon providing a user input indicative of the selection of the object 120. The mobile device 102 may comprise a user interface arranged for receiving further user input related to setting these preferences. This may be beneficial, because it may help users in recognizing their own light effects,
The system may further comprise a mobile device 102 comprising a light detector (e.g. a photodiode or a camera) for detecting light comprising an embedded code, which embedded code is representative of the object information. The mobile device 102 may further comprise a processor (not shown in
The controller may be arranged for determining a first light setting and a second light setting based on the object information, whereupon the controller may control the first light source 410 and the second light source 412 according to the light settings. This is beneficial because the object information is communicated to a user via light (i.e. via the two light sources). For example, the object information about the object 120 may be related to available colors of the object 120. The controller may control the first light source 410 according to a green light setting, and the second light source 412 according to a red light setting. As soon as the red colored object 120 is no longer available, the controller may control the second light source 412 according to the green setting, or, alternatively, according to another color that is available. If the user wishes to receive more information about what the colors of the light mean, he or she can point the light detector of the mobile device 102 to the light sources 410, 412, whereupon the processor retrieves the code, and therewith the additional object information, from the detected light. The processor may further render the object information on a display of the mobile device 102. The processor may, for example render the available colors of the object on the display. In another example, the object information about the object 120 may be related to reviews of the object 120. The controller may control the first light source 410 according to a bright green light setting (indicating that many people like this object 120), and the second light source 412 according to a dim red light setting (indicating that not many people dislike this object 120). As soon as more people start disliking the object 120, the controller may dim the first light source 410 and increase the brightness of the second light source 412. If the user wishes to receive more information about what the colors of the light mean, he or she can point the light detector of the mobile device 102 to the light sources 410, 412, whereupon the processor may retrieve the code, and therewith the additional object information, from the detected light. The processor may further render the object information on a display of the mobile device 102. The processor may, for example render the popularity value (e.g. the number of positive and the number of negative reviews) on the display.
The controller may be further arranged for controlling the first light source 410 and/or the second light source 412 such that the first light source and/or the second light source emit(s) the embedded code representative of the object information about the object 120. This requires a user to point the light detector of the mobile device 102 to the light sources 410, 412 in order to receive the additional object information. Alternatively, the processor may control a third light source such that it emits light comprising the embedded code. This may be beneficial, because a change in color, saturation and/or brightness of the first and second light source will not influence the signal strength of the code embedded in the light.
The controller may be further arranged for controlling the first light source 410 such that it emits a first embedded code, which first embedded code is representative of first object information about the object, and for controlling the second light source 412 such that it emits a second embedded code, which second embedded code is representative of second object information about the object. In this embodiment, the light detector may be arranged for detecting light comprising the first embedded code and detecting light comprising the second embedded code. The processor may be further arranged for retrieving the first embedded code and the second embedded code from the respective light, and for retrieving the first object information and the second object information from the respective codes, and for rendering the first object information and the second object information on the display. The first light source 410 may, for example, emit a code representative of the number of likes of the object, and the second light source 412 may, for example, emit a code representative of the number of dislikes of the object.
The mobile device 102 may comprise a camera for capturing an image 104 of the first light source 410 and the second light source 412. The processor may be further arranged for rendering the image 104 on a display and rendering a virtual representation of the object information as an overlay on the image 104. Additionally, the processor may be arranged for determining a first light source position 410′ of the first light source 410 and a second light source position 412′ of the second light source 412 in the image 104. The processor may be further arranged for determining a position of the virtual representation on the display, wherein the position is related to at least one of the first light source position and the second light source position in the image, and for rendering the virtual representation of the object information at the position. This may be executed by the processor according to any one of the above-mentioned examples, wherein the position of the virtual representation is determined based on the position of the object. This enables the processor to provide the object information in the vicinity of the light sources in the image. Additionally, the processor may determine the position of the object 120 and/or object features in the image, and takes this position into account while determining the position of the virtual representation.
The controller may be further arranged for determining the first and second light settings based on a user profile of the user operating the mobile device 102. The controller may be arranged for accessing the user profile (e.g. a social media profile, a user profile stored on the mobile device, etc.). The controller may further select the object information from a set of stored object information based on the user profile. For example, the controller may retrieve from the user profile that a user has a certain foot size, and provide availability information about the sizes of a shoe (the object 120). In another example, the controller may receive information about how many friends of a user own an object 120, and determine the first light setting and the second light setting based thereon for each product of a plurality of products. This enables a user to see how many of his or her friends own an object 120 (e.g. a pair of shoes, or shoes of a specific brand).
The first and the second light sources may be comprised in a linear lighting device, such as an LED strip. The linear lighting device may comprise a plurality of individually controllable light sources, and the controller may be arranged for controlling each of the plurality of light sources. The controller may be further arranged for determining which light sources to control according to the first light setting and which light sources to control according to the second light setting based on the object information.
The above-mentioned system may comprise different components, ranging from mobile devices to controllers, memories and light sources. It should be understood that these components may be coupled to each other, comprised in each other and/or that these components may be arranged for communicating with each other. The components may comprise transmitters and/or receivers arranged for communicating amongst each other. The transmitters and/or receivers may comprise hardware for transmitting and or receiving messages and/or control commands via any wired or wireless communication protocol. Various wired and wireless communication protocols may be used, for example Ethernet, DMX, DALI, USB, Bluetooth, Wi-Fi, Li-Fi, 3G, 4G or ZigBee. A specific communication technology may be selected based on the communication capabilities of the light sources, the controller and/or the mobile device, the power consumption of the communication driver for the (wireless) communication technology and/or the communication range of the signals.
It should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be able to design many alternative embodiments without departing from the scope of the appended claims.
In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. Use of the verb “comprise” and its conjugations does not exclude the presence of elements or steps other than those stated in a claim. The article “a” or “an” preceding an element does not exclude the presence of a plurality of such elements. The invention may be implemented by means of hardware comprising several distinct elements, and by means of a suitably programmed computer or processing unit. In the device claim enumerating several means, several of these means may be embodied by one and the same item of hardware. The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage.
