- the URL provided by Ad mapper for specific ad item is a generic URL that will be understood by Ad server.
- Ad server At the time of ad content download in the display device (TV/STB), the Ad server will provide the content relevant at that point of time. This avoids changing the stream that is transmitted from the content creation/transmission end.
- the gaze metadata can have following details:
- FIG 3 is an illustration of a system 300 as also shown in Figures 1 and 2 in an example home setting 380.
- users 320, 321, and 322 are interacting with a device 325, for example, watching a television showing content or programming 340 supplied, for example, via a set top box or other consumer premises equipment (CPE).
- CPE consumer premises equipment
- a camera located in the CPE is used to capture gaze data associated with each viewer and used to determine the gaze profile of each user.
- a remote ad server 360 comprises user profile mapping 310 and AOI to ad mapping 330 capabilities.
- the user profile mappings of the ad server 360 are shown in table 310. These mappings show the profiles for each user based on each user’s gaze mapping.
- the area of interest (AOI) in the programming current to the users is the wristwatch 342 on the wrist of the man displayed on the screen of television 325.
- Module 330 stores the various areas of interest (AOIs) 331, 332, 333 with EIRLs 335, 336, 337 to corresponding advertising.
- the wrist watch 342 shown in the programming 340 matches the entry in the table 330 to AOI 2 332 which corresponds to the EIRL 336 to advertising of the targeted product (in this case the wrist watch 342).
- the advertising server 360 receives the information about the desired advertisement related to AOI 332 and its EIRL 336 and renders the advertisement content to be inserted into the programming content 340 shown on the viewer device 325.
- the method shown in Figure 4 illustrates a method 400 for gaze advertising using the (x,y) coordinates of the advertising item.
- the IP camera captures the viewer’s image.

- the (x,y) coordinates of a user attention on the display device is output.
- a gaze meta data parser parses the data.
- the data here refers to media content (video stream) that contains the gaze meta data inserted at content distribution end.
- the gaze metadata parser receives gaze meta data from the media content (different embodiments to how gaze metadata can be part of the media content are later disclosed).
- an area of interest is calculated.
- the area of interest corresponds to the advertising items.
- the area of interest is compared to the (x,y) coordinate to see if it matches the viewer attention. If yes, at step 495, the method then moves to select the advertising URL and render the advertisement.
- FIG. 5 illustrates a method 500 for gaze advertisement using a quadrant method.
- the IP camera captures the viewer image.
- gaze detection is accomplished via a method referred to herein.
- the (x,y) coordinates of the user attention on the display device are output.
- Module 510 outputs the (x,y) coordinates of user attention on the display device.
- a gaze meta data parser parses the data related to the user’s gaze.
- metadata should contain the number of quadrants into which the frame is divided.
- the (x,y) coordinate of the viewer attention is compared to see if it falls on a quadrant, and which one. If yes, at step 580, the advertising URL is selected and the advertisement is rendered for insertion into the viewer’s programming.
- a reasonable time threshold is used to match viewer's gaze data with the AOI provided by gaze metadata, to avoid false positive matches, when deciding to select / play the Ad.
- the process in Figure 6 depicts a method 600 for gaze advertising using head pose estimation.
- the field of real-time head movement detection has received much attention from researchers.
- the pose of an object refers to its relative orientation and position with respect to a camera.
- the pose can change by either moving the object with respect to the camera, or the camera with respect to the object.
- the pose estimation disclosed can be one of many methods and is outside of the scope of the disclosed embodiments.
- the goal is to find the pose of a viewer when there is a calibrated camera, as shown in the figures, and, for example, the locations of n 3D points on the object and the corresponding 2D projections in the image are known or can be ascertained.
- the IP camera captures the viewer image.
- gaze detection is accomplished using image processing that uses the head pose estimation method.
- the gaze direction 615 is output.
- a gaze meta data parser parses the data related to the user’s gaze direction.
- metadata contains information that is used to determine whether the advertisement is present in the left or right half of the frame.
- step 650 the gaze direction is compared to the meta data for a match. If there is a match, the method advances to step 680, and the corresponding advertising URL is selected, and the advertisement content is rendered.
- gaze responsive advertisement for larger display needs are disclosed.
- content providers and/or service providers insert gaze-related information as meta-data, such as the location of the object/item that needs to be advertised in the video frame, using which the display device can identify the advertised item or object.
- the display device/ STB as described above, will parse the gaze meta-data.
- the display device can calculate the area of interest (AOI).
- AOI area of interest
- the IP camera-enabled display device/STB can contain gaze processor which can help the display device to identify the viewers point of attention. If the viewers point of attention matches with AOI derived from gaze meta data, the display device/ STB can tune to the advertisement present in advertisement server.
- the content provider or service provider can add the gaze data in any preferred method.
- the gaze data comprises different types of meta data.
- the Gaze meta data comprises one or more of the following types of data: a. (x,y) Co-ordinates, height and width of the object that needs to advertised. Using this information, the display device can derive the AOI.
- This URL can be used by a display device/ STB to select an advertisement.
- the gaze detecting processing can be simplified by several methods.
- One of the methods to make the gaze detection simpler for the display device is to utilize quadrant data.
- the service/content provider can indicate the quadrant where the advertised object is present in the video frame.
- One embodiment using this method could be that the video frame is divided into four (4) quadrants and the content/service provider can indicate in which quadrant (1,2,3, or 4) the advertised object is present.
- a display device needs a complex gaze detection algorithm to identify the accurate co-ordinates of a viewer’s eye attention on a display screen. Detecting the orientation of a viewer’s face can be much easier compared to detecting the exact location of a viewer’s’ attention on display screen. Detecting the orientation of a viewer’s face can utilize a less complex algorithm compared to detecting the accurate gaze co-ordinates of a viewer’s face.
- This set of gaze-data comprises: a. JPEG image URL - the image that is targeted to be displayed on display device. b. Direction: Indicates the display device where it needs to display the JPEG image.
- the Direction can be LEFT or RIGHT. If Direction is LEFT, the display device should present the JPEG poster on the left side of the screen. When this direction matches with the orientation of viewer’s face detected by gaze-detection algorithm, then display device should select the advertisement. c. Advertisement URL. - Location of the advertisement. d. Duration: Indicates the amount of time the display device should display the JPEG image. e. AdTriggerDuration: This data is optional and indicates minimum of amount of time the viewer should gaze at the poster consistently after which advertisement can be presented.
- the gaze meta data can be part of SEI NAL of H264/AVC or can be part of separate data PID in MPEG2 Transport system or can be part of meta data WebVTT.
- An example WebVTT for gaze meta data comprises:
- VTTKind metadata
- VTTDataHint Eye-Gaze Data
- the sample payload of JSON object can be any sample payload of JSON object.
- the CPE device can contain a wide-angle IP camera which can be configured to capture the viewers face and feed these frames to the gaze processor.
- the gaze processor can comprise the following features:
- the CPE devices can have image processing capability which can process the frames captured by the IP camera and detect the viewers’ attention.
- Open source image processing libraries like OpenCV, Dlib are available which can be used to implement the gaze detection
- Gaze detection algorithm can be a complex algorithm which could derive the exact location (x,y) co-ordinates at which viewers eyes are gazing.
- a much easier gaze algorithm can be used to just provide information related to viewer head pose and orientation.
- multi- viewers scenario can be considered by which targeted advertisement can be achieved.
- the CPE device can parse the gaze-meta data present in the content and calculate the area of interest.
- Gaze user profile If there are multiple viewers, the gaze processing algorithm can use face detection and determine a profile that has to be used in advertisement selection. There could be multiple profiles defined, depending on the combination of viewers. Also, there can be a priority mechanism in choosing the viewer, when multiple viewers are present, when doing the gaze processing.
- aspects of the subject matter described herein may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer.
- program modules include routines, programs, objects, components, data structures, and so forth, which perform particular tasks or implement particular abstract data types.
- aspects of the subject matter described herein may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network.
- program modules may be located in both local and remote computer storage media including memory storage devices.
