Abstract:
A system and method for monitoring media viewing activity by one or more individuals is disclosed. In general, the location of a sign can be identified, a human eye can be located and tracked and vectoring module and a projection module can determine if the individual&#39;s eyes are directed towards the sign. The content of the signage can be coordinated with the direction of the eye in real time to determine what content the individual viewed. An audience reaction module can acquire audience reaction data such as how long eyes are engaged on the sign and can determine other reactions such as a smile a frown or a gesture of interest or disinterest based on the change of content on the signage. The system allows for an advertiser to acquire and evaluate audience feedback related to presentation and content displayed on media (e.g., billboards, digital signage, window displays, etc.).

Description:
TECHNICAL FIELD 
       [0001]    Embodiments are generally related to the collection of audience response data for the generation and calculation of advertising metrics. Embodiments are additionally related to eye tracking devices 
       BACKGROUND OF THE INVENTION 
       [0002]    Billboards are utilized to impart advertising information to passengers, drivers and pedestrians within view of the billboard. A typical billboard is a large outdoor advertising structure usually found in high traffic areas such as alongside busy roads. Billboards present large advertisements to passing pedestrians and drivers. Typically showing large, ostensibly witty slogans, and distinctive visuals, billboards are highly visible in the top designated market areas. Bulletins are the largest, most impactful standard-size billboards. Located primarily on major highways, expressways or principal arterials, they command high-density consumer exposure (mostly to vehicular traffic). Bulletins afford greatest visibility due not only to their size, but because they allow creative “customizing” through extensions and embellishments. Billboards are an ideal place to advertise business because rather than you having to find your customers, your customers will find your advertising 
         [0003]    Posters represent another common form of billboard advertising, located chiefly in commercial and industrial areas on primary and secondary arterial roads. Posters are a smaller format than bulletins and are viewed principally by residents and commuter traffic, with some pedestrian exposure. Yet smaller outdoor advertising displays are Kiosks, prevalent at buss stops, train stations, on and in busses, in subways, along busy walkways etc. 
         [0004]    Most billboards and similar advertising media are static. Recently, however, the advertising industry has moved toward electronic billboards and similar digital displays, which are capable of imparting a wide variety of different types of advertisements in a single digital display over a shorter period of time. 
         [0005]    Electronic billboards and electronic signs are most common in major cities such as Las Vegas, New York and Tokyo, where large-format electronic signs deliver advertising via static, periodic posting and dynamic video content to passers-by. Although the display technologies may vary widely, electronic signs and billboards all require some type of content source to generate the images on the display. Depending on regulatory and technical considerations, this content can be a series of static slides (periodic postings), or a sequence of broadcast-quality video and animation. 
         [0006]    One of the problems with such advertising media is the poor ability to track how often the advertisements actually reach an intended target or make an “impression” on passing drivers, pedestrians, passengers, and so forth. Current approaches to this problem do not readily enable tracking mobile viewers of billboard advertising, especially those in a vehicle (e.g., automobile, trucks, trains, etc). 
       BRIEF SUMMARY 
       [0007]    The following summary is provided to facilitate an understanding of some of the innovative features unique to the disclosed embodiments and is not intended to be a full description. A full appreciation of the various aspects of the embodiments disclosed herein can be gained by taking the entire specification, claims, drawings, and abstract as a whole. 
         [0008]    It is, therefore, one aspect of the disclosed embodiments to provide for an improved system and method for monitoring audience response to advertising activity. 
         [0009]    It is another aspect of the disclosed embodiments to provide for a system and method for tracking responses of mobile viewers to different forms of advertising. 
         [0010]    It is an additional aspect of the disclosed embodiments to provide a system and method for tracking the number of mobile viewers of billboard advertising, especially those traveling in a vehicle (e.g., automobile, trucks, trains, etc). 
         [0011]    The aforementioned aspects and other objectives and advantages can now be achieved as described herein. 
         [0012]    In accordance with one aspect of the disclosed embodiments, a system and method for monitoring media viewing activity is disclosed. In general, an eye tracking device is employed for monitoring the eyes of one or more individuals in a vehicle with respect to information displayed on media external to the vehicle and in view of the monitored individual. A surveillance device generates a view of the information displayed on media external to the vehicle. The surveillance device communicates with the eye tracking device in order to correlate data collected from the surveillance device and the eye tracking device, the data indicative of a positive posting of the information to thereby enable a valuation of the information displayed on the media (e.g., billboards, digital signage, window displays, etc.). Such a system and/or method thus enable eye tracking of mobile viewers in vehicles (automobiles or similar), including correlation of the eye movement and outdoor view to the actual surrounding billboard display devices. 
         [0013]    In accordance with another aspect of the disclosed embodiments, a system for monitoring media viewing activity is disclosed. Such a system generally includes an eye tracking device for monitoring an eye of an individual (e.g., a driver or a passenger) in a vehicle with respect to information displayed on media external to the vehicle and in view of an individual in the vehicle. A surveillance device can be employed for generating a view of the information displayed on media external to the vehicle, the surveillance device in communication with the eye tracking device in order to correlate data collected from the surveillance device and the eye tracking device, the data indicative of a positive posting of the information to thereby enable a valuation of the information displayed on the media. 
         [0014]    In such a system, the eye tracking device and the surveillance device are preferably attached to the vehicle. Additionally, a data-processing apparatus such as, for example, a processor can be provided for processing and correlating the data collected from the surveillance device and the eye tracking device. The processor is capable of communicating electronically with the eye tracking device and the surveillance device. Additionally, a solar powered device can be employed for providing electrical energy to the eye tracking device, the surveillance device, and/or the processor and associated components. A memory can also be utilized for storing information output by the eye tracking device and the surveillance device. 
         [0015]    In accordance with another aspect of the disclosed embodiments, a method for monitoring media viewing activity is disclosed. In such an embodiment, a logical operational step can be implemented for monitoring utilizing an eye tracking device, at least one eye of at least one individual in a vehicle with respect to information displayed on media external to the vehicle and in view of the monitored individual. A logical operational step can be then implemented for generating a view of the information displayed on media external to the vehicle utilizing a surveillance device that communicates with the eye tracking device in order to thereafter correlate data collected from the surveillance device and the eye tracking device, so that the data is indicative of a positive posting of the information and thereby enables a valuation of the information displayed on the media. An additional logical operational step can include processing and correlating the data collected from the surveillance device and the eye tracking device utilizing a processor. Such a method can further include the step of storing in a memory information output by the eye tracking device and the surveillance device. Such a method can also include a step of providing electrical energy to the eye tracking device and the surveillance device utilizing a solar powered device.

     DETAILED DESCRIPTION 
       [0024]    The particular values and configurations discussed in these non-limiting examples can be varied and are cited merely to illustrate at least one embodiment and are not intended to limit the scope thereof. 
         [0025]      FIG. 1  illustrates a block diagram of a system  100  for monitoring media viewing activity, in accordance with the disclosed embodiments. Note that in  FIGS. 1-7 , identical or similar parts or elements are indicated by identical reference numerals. System  100  depicted in  FIG. 1  includes an eye tracking device  102  that monitors an eye of an individual in a vehicle, such as vehicle  304  of  FIG. 3  with respect to information displayed on media external to the vehicle  304  and in view of the individual. System  100  also includes a surveillance device  104  for generating a view of the information displayed on media external to the vehicle  304 . The surveillance device  104  communicates with the eye tracking device  102  in order to correlate data collected from the surveillance device  104  and the eye tracking device  102 , the data indicative of a positive posting of the information to thereby enable a valuation of the information displayed on the media, such as, for example, billboard  302  depicted in  FIG. 3 . 
         [0026]      FIG. 2  illustrates a block diagram of a system  200  for monitoring media viewing activity, in accordance with the disclosed embodiments. The configuration depicted in  FIG. 2  is a variation to the system  100  illustrated in  FIG. 1 . System  200  includes the eye tracking device  102  for monitoring the eye(s) of an individual in the vehicle  304  with respect to information displayed on media (e.g., billboard  302 ) external to the vehicle and in view of the individual. System  200  also includes the surveillance device  104  for generating a view of the information displayed on media external to the vehicle  304 . System  200  additionally includes a processor  202  for processing and correlating the data collected from the surveillance device  104  and the eye tracking device  102 . 
         [0027]    A memory  204  can also be included as a part of system  200  for storing information output by the eye tracking device  102  and the surveillance device  104 . Note that the processor  202  can be implemented as, for example, a CPU (Central Processing Unit) or the portion of a data-processing system/apparatus (e.g., a computer, server, etc) that carries out the instructions of a computer program as the primary element for carrying out the data-processing functions of such a computer (not shown). Processor  202  may also be implemented as a microprocessor, which incorporates most or all of the functions of a CPU on a single IC (Integrated Circuit) or a group of electronically interlinked IC&#39;s. 
         [0028]    The memory  204  may be, for example, a flash memory or another non-volatile computer storage medium that can be electrically erased and reprogrammed. Memory  204  may be, for example, a memory card or even a USB flash drive for general storage and transfer of data between computers and other digital products. In some embodiments, memory  204  can also be a specific type of EEPROM (Electrically Erasable Programmable Read-Only Memory) that is erased and programmed in large blocks; in early flash the entire chip had to be erased at once. 
         [0029]    The system  200  can be configured to further include a controller  206 , which may be, for example, a chip or extension card that interfaces with the devices  102  and  104 , and can function as a link to the memory  204  and devices external to system  200 . 
         [0030]      FIG. 3  illustrates a pictorial diagram of the vehicle  304  equipped with the eye tracking device  102  and the surveillance device  104 , in accordance with the disclosed embodiments. The eye tracking device  102  can be mounted within the vehicle  304  in a strategic location, such as, for example on or near a rear view mirror located proximate to the front passenger seat. Alternatively, the eye tracking device  102  can be located at other positions in the vehicle  304  or can be composed of a number of eye tracking devices within the vehicle  304 . The surveillance device  104  can be located and attached to the vehicle  304  at, for example, one of the side mirrors of the vehicle  304 . It can be appreciated that the surveillance device  104  can be located at other positions on the vehicle or can be composed of a group of such surveillance devices at strategic locations on the vehicle  304 . 
         [0031]    Thus, one or more eye tracking devices such as the eye tracking device  102  can be attached to a mirror (e.g., the rear view mirror) of vehicle  304  or another area of the vehicle  304  that are in view of the driver and that enables the driver&#39;s eye(s) to be tracked as it moves to look at surrounding display information and media, such as billboard  302  or other media such as digital signage, window displays, etc. The second device  204  is also attached to the vehicle  304  to provide a view of the surrounding information outside the vehicle  304 , such information displayed on the billboard  302 . 
         [0032]    The views are correlated based on the eye tracking input for the direction of the visual view of the outside area and the second device  104  view of the outside area. Thus, the paired devices  102  and  104  can enable tracking the eye(s) of the driver of the vehicle  304  and tracking the outside display devices in the field of view, and the information would be correlated to provide positive information about the signage information viewed by the driver of the vehicle  304 . In advertising terms this can be related to proof of performance or “posting” for the display information. Note that in some embodiments, an optional solar powered device can be utilized to supply electrical energy to the various components, such as devices  102 ,  104 , and so forth. Such a solar powered device can include a solar panel located on the vehicle  304 . 
         [0033]      FIG. 4  illustrates a schematic diagram of a particular eye tracking device, in accordance with an embodiment. Note that the eye tracking device  102  can be implemented in the context of different embodiments. For example, in one embodiment, the eye tracking device  102  can be configured as a palm-sized video camera  401  surrounded by one or more light emitting diodes, such as, for example, infrared light emitting diodes  402 ,  404 ,  406 ,  408 ,  410  and  412 . Such a device  102  can be configured to record eye contact with, for example, 15-degree accuracy at a distance of around 33 feet, depending upon design consideration. A simple glance from a passenger in the vehicle  304 , for example, can record an impression which is utilized to compute a tally that enables measurement metrics that advertisers (e.g., associated with billboard  302 ) may rely upon for accurate advertising data. 
         [0034]    It can be appreciated, of course, that the eye tracking device  102  can be implemented utilizing a number of eye tracking devices and techniques. The eye tracking device  102  can be configured to measure either the point of gaze (i.e., where the individual is looking) or the motion of an individual&#39;s eye (or eyes) relative to his or her head. The eye tracking device  102  can measure eye positions and/or eye movement. The eye tracking device  102  can utilize a non-contact and optical component and methodology for measuring eye movement. Light, typically infrared, is reflected from the eye and can be sensed by a video camera, such as, for example, the video camera  401  or some another designed optical sensor. 
         [0035]    In some embodiments, information can be then analyzed to extract eye rotation from changes in reflections. A video based eye tracker, for example, typically utilizes the corneal reflection and the center of the pupil as features to track over time. A more sensitive type of eye tracker, such as the dual-Purkinje eye tracker, can utilize reflections from the front of the cornea and the back of the lens as features to track. A still more sensitive method of tracking involves the imaging of features from inside the eye, such as the retinal blood vessels, and follows these features as the eye rotates. Optical methods, particularly those based on video recording, are preferably utilized for gaze tracking and are favored for being non-invasive and inexpensive. 
         [0036]    Another example of an eye tracking device and related components and methodologies that can be utilized to implement the eye tracking device  102  is disclosed in U.S. Patent Application Publication No. US20030142041A1 entitled “Eye Tracking/HUD System” which was published on Jul. 31, 2003 by Barlow et al. U.S. Patent Application Publication No. US20030142041A1, which is incorporated herein by reference, describes an apparatus for eye tracking, including: an illuminator; reflection apparatus to reflect illumination from the illuminator onto a surface of a windshield of a vehicle in which the windshield is installed, such that the illumination is reflected onto at least an eye of a person in the vehicle, and to reflect an image of the at least an eye, and a sensor to receive a reflection of the image of the at least an eye reflected by the reflection apparatus and to produce an output signal representative thereof. It can be appreciated, of course, that the device of U.S. Patent Application Publication No. US20030142041A1 is discussed herein for general exemplary and illustrative purposes only and is not considered a limiting feature of the disclosed embodiments. 
         [0037]    The surveillance device  104  can be implemented as, for example, a digital video camera for obtaining a view of the areas and in particular media, such as billboards, located in view of the individual in the vehicle  304  as the vehicle  304  passes by such a billboard or other outdoor advertising medium. 
         [0038]      FIG. 5  illustrates a block diagram of a system  500  for monitoring media viewing activity, in accordance with the disclosed embodiments. In the particular embodiment depicted in  FIG. 5 , a system  502  is illustrated, which his composed of the eye-tracking device  102 , the surveillance device  104 , and the processor  202 . The system  502  can communicate with a network  504 , which in turn communicates with one or more servers, such as a server  506 . The network  504  may comprise, for example, a cellular communications network, which is a radio network composed of radio cells (or simply “cells”) served by at least one fixed-location transceiver known as a cell site or base station. These cells cover different land areas to provide radio coverage over a wider area than the area of one cell, so that a variable number of portable transceivers can be used in any one cell and moved through more than one cell during transmission. 
         [0039]    Network  504  may also constitute, for example, a wireless network such as an 802.11 network and variations thereof. In other embodiments, network  504  can be, for example, the Internet, which is the global system of interconnected computer networks that use the standardized Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. The Internet is a network of networks that includes millions of private and public, academic, business, and government networks of local to global scope that are linked by copper wires, fiber-optic cables, wireless connections, and other technologies. The Internet carries a vast array of information resources and services, most notably the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail. 
         [0040]    As indicated by the embodiment depicted in  FIG. 5 , data can be collected by the eye tracking device  102  and the surveillance device  104  and processed by the processor  202  and then automatically uploaded via a wireless interface through network  504  (e.g., cellular network, WiFi, etc) to one or more server(s)  506 , where such data can be stored and then retrieved by an advertiser  504  or other media analyst for evaluation and review. 
         [0041]      FIG. 6  illustrates a high-level flow chart depicting logical operation steps of a method  600  for tracking mobile viewers of media advertising, in accordance with the disclosed embodiments. It can be appreciated that the various steps depicted in  FIG. 1  can be implemented in some embodiments by executing a program instruction in a data-processing apparatus, such as a processor, a computer, a server, etc. 
         [0042]    As indicated at block  602 , an operation can be implemented for monitoring the eye(s) of an individual in a vehicle utilizing an eye tracking device, such as, for example, eye tracking device  102 , and with respect to information displayed on media (e.g., billboards) external to the vehicle and in view of the individual. Next, as depicted at block  604 , a view of the information displayed on media external to the vehicle can be generated utilizing a surveillance device that communicates with the eye tracking device. 
         [0043]    Thereafter, as described at block  606 , data can be collected from the eye tracking device and the surveillance device. Next, as indicated at block  608 , the data collected from the surveillance device and the eye tracking device can be processed and correlated such that the data is indicative of a positive posting of the information and can be utilized to enable a valuation of the displayed information (e.g., advertisements). The method  600  thus enables eye tracking for mobile viewers in vehicles (automobiles or similar), including correlation of the eye movement and outdoor view to the actual surrounding billboard display devices. 
         [0044]      FIG. 7  illustrates a schematic diagram of a system  700  for monitoring media viewing activity, in accordance with the disclosed embodiments. System  700  includes one or more eye tracking devices, such as, for example, eye tracking devices  109  located on-axis of a roadway or a vehicle field of view. System  700  further includes the surveillance device  104 , which monitors external objects such as a building  703 , the billboard  302  and so forth, while the eye tracking devices such as  109  monitor the human eye  103  of a passenger or a driver in the vehicle  304 . An antenna  702  may be utilized to wirelessly transmit information to and from the network  504  as discussed earlier. 
         [0045]    Thus, in the configuration depicted in  FIG. 7 , a scene is depicted which includes the billboard  302  with content and located near a building or house  703  with, for example, mountains in the background and the antenna  702 . Angles from the eye-to-billboard such as angle  107  and device-to-billboard such as angle  111  are depicted in  FIG. 7 , which indicate the analytical process for measuring and correlating the view as seen by each detector. Detection of the angle  111  from on-axis centerline of the roadway  109  for the surveillance monitor  104  to the billboard  302 , represented by line  102 , can be correlated to the angle  107  from on-axis of the roadway  109  for the eye  103  to the billboard  302 , represented by line  105 , thereby confirming the eye is looking at the billboard  302  in the field of view of the surveillance monitor  104 . 
         [0046]      FIG. 8  illustrates an audience reaction system  800  in accordance with another embodiment. The system  800  can include a signage location module  802 , an eye identification module  804 , an eye location module  806 , an eye vector module  808 , a projection calculation module  810  and an audience reaction module  812 . It can be appreciated that such modules can be implemented as physical hardware components and/or software modules, including computer-implementable instructions for performing particular tasks, such as signage location, eye identification, eye location, eye vector calculations, projection calculations, audience reaction processing and so forth. 
         [0047]    In some embodiments the signage location module  802  can receive input regarding sign locations wherein sign owners and advertisers are interested in determining how many impressions are received and any other data associated with the impressions. The sign location module  802  can include a database or other memory location that stores three dimensional locations of the facial surface of the sign. This data can be automatically acquired utilizing, for example, satellite photographs and references to known locations. Thus, sign location module  802  can store a locus of points based on latitude, longitude, elevation coordinates and the dimension of the face of the sign (e.g., billboard  302 ). 
         [0048]    The eye identification module  804  can be, for example, a camera supported by recognition software and the eye identification module  804  can use technologies such as edge detection technology and can provide an output signal to the eye location module  802  after the eye identification module  806  locates one or more human eyes. 
         [0049]    In response to the signal the eye location module  806  can determine a location of the eye. The eye location module  806  can determine an latitude longitude, elevation and speed component of the eye using a global positioning system (GPS) receiver. All locations disclosed herein can be defined using latitude, longitude, and elevation coordinates via a GPS receiver. In some embodiments the eye vector module  808  can monitor the identified eye and can determine a relative direction which the eye is directed from the location of the eye. 
         [0050]    The eye vector module as well as the other modules disclosed herein can be on a person, in a vehicle or can be mounted in a fixed location relative to the sign. Using the relative direction and the location of the eye, a projection calculation module  806  can calculate the direction of an individual&#39;s visual attention by projecting the relative direction from the eye location and use the locus of points in the sign location module database  802  to determine if the individual is visually engaged with the sign. Thus, if the projection of the eye direction from the location of the eye intersects the second location (locus of points) within a particular range such as for example 5,000 feet from the eye to the sign location eye projection module  806  can send a signal to the audience reaction module  812 . 
         [0051]    In response to the signal the audience reaction module can monitor additional parameters such as duration of eye contact with the sign, scanning of the sign, changes in features of the face such as smiling etc. These changes can be converted into advertising metrics such as number of impressions, duration of attention, demographic information of the viewer, what kind of car the viewer is in, what the viewer is wearing, how fast moving etc. 
         [0052]    The system can include a correlation module  814  to correlate what is being displayed on the sign when the individual is engaged with the sign. The correlation module  814  can utilize a clock and the audience reaction module can use a clock to correlate data by time stamping the data. The audience reaction module can use the clock to determine a duration that the eye is directed in particular direction and average engagement times can be calculated for many viewers different audiences etc. 
         [0053]    The audience reaction module  812  logs in “real time,” a number of different eyes that are directed towards the sign. The audience reaction module  812  can also log changes in facial features or other actions or gestures before during and after an individual views a sign. For example, the audience reaction module  812  can determine if the individual takes an action like closing their eyes, quickly focusing back on the road, reaches for or activates a cell phone or the dials on a radio. The eye vector module can calculate a field of view range in degrees based on the proximity of the eye to the sign and the width of the sign and can also determine a particular location on the sign (e.g., billboard  302 ) the individual is focusing on. 
         [0054]    In some embodiments, the eye vector module  808  can use a velocity of the eye as determined by the eye location module to determine if the projection intersects the billboard location and to improve the accuracy of the system. In some embodiments the audience reaction module can determine the affects of viewer speed using advertising metrics and the reactions made by the individual when viewing the signage. All of the modules  802 - 814 , for example, can employ a processor (or a group of processors) to process and correlate data (e.g., data collected by the audience reaction module). Monitoring can be performed on digital billboards where the face provides a dynamic or digital display. 
         [0055]    System  800  thus can include the use of the signage location module  802  to provide a first location of a sign. The eye identification module  804  can transmit a signal in response to locating an eye of a human. The eye location module  806  can determine a second location of the eye in response to the signal. The eye vector module  808  can determine a first relative direction to which the eye is directed from the first location. The projection calculation module  810  can be utilized to project the first relative direction from the first location and determine if the projection intersects the second location. The audience reaction module  812  can monitor at least the eye and determine an advertising metric. 
         [0056]    Additionally, the eye vector module  806  can determine the relative direction in one dimension. In other embodiments, system  800  can be configured to further include a correlation module  814  to correlate what is displayed on the sign with the advertising metric. A clock  816 , can also be coupled to the audience reaction module  812  to time stamp the advertising metric. The audience reaction module  812  can utilize the clock determine a minimum time that the eye is directed in particular direction. The first and second location can be defined, for example, in latitude and longitude coordinates. In some embodiments, the audience reaction module  812  can log in real time, a number of different eyes that are directed towards the sign. 
         [0057]    Additionally, the audience reaction module  812  can log changes in facial features. The eye vector module  808  can also, in some embodiments, be located in a vehicle, such as, for example, vehicle  304  illustrated and described herein. The eye vector module  808  can be mounted in a fixed location relative to the sign. The eye vector module  808  can calculate a field of view range based on the first location the second location and a dimension of the face of the sign. Additionally, in some embodiments, the projection calculation module  810  can detect the velocity associated with the eye and utilize the velocity to determine if the projection intersects the second location. A processor  817  can also communicate with each of the aforementioned modules and can process and correlate data collected by the audience reaction module  812 . The sign (e.g., billboard  302 ) can, in some embodiments, constitute a dynamic digital display. 
         [0058]    System  800  can also, in some embodiments, utilize a GPS (Global Positioning Satellite) receiver  818  to determine one of the first location or the second location. The GPS receiver  818  can be configured to communicate with each of the aforementioned modules along with the processor  817 , etc. Note that in other embodiments, the signage location module  802  can accept three dimensional sign location data from the GPS receiver  818  and store the sign location data in a database or other appropriate memory location (not shown in  FIG. 8 ). The eye location module  806  can also utilize the GPS receiver  818  to determine the second location. The first location can additionally be acquired using satellite transmissions.
