An interactive display system includes a display and an imaging unit or camera. The interactive display system tracks a subject's eyes or head movement to determine a subject's interest. Then, the system will analyze the subject's behavior and make decisions on what content to display on a screen based on the subject's interest. ## Claims ### Claim 1 A method comprising: receiving first, second, and third content for display on a first display; storing the first, second, and third content in a memory; displaying the first content on the first display; receiving a stream of images from a first imaging device; analyzing the stream of images from the imaging device to obtain a first analysis; and based on the first analysis of the images, altering the content shown on the first display to show either the second content or the third content, wherein the content shown on the first display does not comprise images received using the first imaging device. ### Claim 2 (depends on 1) The method of claim 1 wherein the first, second, and third content are received over a network connection. ### Claim 3 A method comprising: receiving first, second, third, fourth, fifth, and sixth content for display on a first display; storing the first, second, third, fourth, fifth, and sixth content in a memory; displaying the first content on the first display; displaying the second content on the second display; receiving a stream of images from a first imaging device; analyzing the stream of images from the imaging device to obtain a first analysis; based on the first analysis of the images, altering the content shown on the first display to show either the third content or the fourth content, wherein the content shown on the first and second displays does not comprise images acquired received using the first imaging device; and based on the first analysis of the images, altering the content shown on the second display to show either the fifth content or the sixth content, wherein the second display is separate from the first display. ### Claim 4 (depends on 1) The method of claim 1 wherein the analyzing the stream of images from the imaging device to obtain a first analysis comprises: in the stream of images, detecting a gaze event of a person, wherein the gaze event indicates a selection by the person's eye gaze of either at least a first portion of the first content or a second portion of the first content shown on the display; upon determining the gaze event is for the first portion, display the second content associated with the first portion on the first display; and upon determining the gaze event is for the second portion, display a third content associated with the second portion on the first display. ### Claim 5 (depends on 1) The method of claim 1 comprising: calibrating the first imaging device and the first display by using a point of interest on the first display at about a frame center, between a frame left edge and a frame right edge of the first display and between a frame top edge and a frame bottom edge of the first display. ### Claim 6 (depends on 1) The method of claim 1 comprising: calibrating the first imaging device and the first display by using a point of interest on the first display moving from a frame left edge to a frame right edge of the first display or the point of interest moving from the frame right edge to the frame left edge of the first display. ### Claim 7 (depends on 1) The method of claim 1 comprising: calibrating the first imaging device and the first display by using a point of interest at one side of a frame of the first display and then at an opposite side of the frame of the first display. ### Claim 8 (depends on 1) The method of claim 1 comprising: using a real-time processor, performing an image analysis of gaze click detection, group classification, movement detection, and location estimation. ### Claim 9 (depends on 1) The method of claim 1 wherein the memory comprises embedded storage or external storage, and the storage is used to store content images received from a server for a presenter and a reporter, and method comprises based on image analysis data, determining associated display content. ### Claim 10 (depends on 1) The method of claim 1 wherein the image analysis comprises determining a gaze duration, estimate face location, and generate a gaze_click flag when a duration is greater than a predetermined threshold time value. ### Claim 11 (depends on 1) The method of claim 1 wherein the image analysis comprises detecting a movement of a person's eyes, a movement of a person's head, and movement of a person's body, a person's gender, a person's age, a person's movement behavior or patterns, a person's distance from first display, a person's hair color, a person's clothing color, a person's clothing style such as pants, skirt, or other, appearance, posture, face recognition or face tracking, or any combination of these. ### Claim 12 (depends on 1) The method of claim 1 wherein the altering the content shown on the display is enabled by generating of a gaze_click_through flag which comprises a gaze_click and weighting factors comprising at least one of a specific gender, age group, specific area, distance, preferred viewers, or other factors, or any combination of these. ### Claim 13 (depends on 1) The method of claim 1 comprising migrating altered content from a primary content group to secondary content group to match to a classified viewer's group. ### Claim 14 (depends on 1) The method of claim 1 comprising updating a content size, including text font size, of the altered content according to a viewer's distance, content color to match viewer's dress color, content waving to get attention, content still from waving, or different content, or any combination of these. ### Claim 15 (depends on 1) The method of claim 1 wherein the imaging device positioned in a separate location than the first display. ### Claim 16 (depends on 1) The method of claim 1 wherein the imaging device is housed in at least one of a mannequin, a merchandise, a holder, or a stand, separate from the display. ### Claim 17 (depends on 1) The method of claim 1 wherein the imaging device incorporates a motor to rotate the imaging device itself or to rotate a front mirror to increase its field of view. ### Claim 18 (depends on 1) The method of claim 1 wherein multiple display units and imaging units are linked together, such that when a subject moves from a display unit A's coverage to a display unit B's coverage, a subject's eye is tracked such that display unit B will display content that related to what was displayed in unit A when the subject's gaze was detected in unit A. ### Claim 19 (depends on 1) The method of claim 1 wherein for each instance content is displayed on the first display, captured images associated with the content on the first display are analyzed to determine an interest level, where lower interest content will be replaced with content similar to high interest content either in a single display or using multiple display units. ### Claim 20 (depends on 1) The method of claim 1 wherein the image analysis comprises detecting a gaze blinking which is used to determine if a real human.
