Abstract
A method capturing eye movement data for detection of cognitive anomalies, includes a computer application displaying a frame on a display, capturing and displaying a video image of a user's face and eyes, while the user aligns the face to the frame, capturing and processing the face image to initiate an image eye movement capture process, outputting an indication on a display and moving the indication spatially to one of a plurality of images, capturing a video of each user eye, to track the position of the indication of the display, the image of each eye comprising a sclera portion, an iris portion, and a pupil portion, parsing the video to determine a reference images corresponding to eye positions, capturing the user's eyes while the user views familiar and novel images, and correlating the images of the user's eyes to the familiar or novel images using the reference images.
Core Innovation
A method for playing a matching game on a host computer is described in which a remote computer system is directed to display selected subsets of static images from a first plurality of static images while inhibiting display of static images from a second plurality of static images. The remote system displays a first static image and a second static image simultaneously, while capturing video data of the player’s eye movements using a web camera during the presentation of the images.
The system creates edited video data from a subset of the video data based on a pre-defined two dimensional area of interest, and provides the edited video data to the host computer. The host computer determines a first amount of time representing an amount of time the player views the first static image and a second amount of time representing an amount of time the player views the second static image, using the edited video data.
The host further determines a viewing relationship for the player between the second amount of time and the first amount of time, and evaluates whether the viewing relationship exceeds a first threshold. In response to this evaluation, the host generates a success flag and provides to the remote computer system an indication that the player is successful in response to the success flag.
Claims Coverage
The provided partial content and relevant claims identify one independent claim. That independent claim includes five inventive features directed to remote static-image presentation, web-camera eye-movement video capture, edited-video generation from a two-dimensional area of interest, host-side determination of view times and a viewing relationship, and success-flag thresholding with feedback to the remote system.
Remote image selection and timed display for a matching game
Directing the remote computer system to display only static images from a first plurality of static images but not static images from a second plurality of static images for a first predetermined amount of time, inhibiting displaying at least one static image from the first plurality of static images for a second predetermined amount of time, and simultaneously displaying a first static image from the first plurality and a second static image from the second plurality upon at most half of the display for a third predetermined amount of time.
Web-camera video capture during simultaneous image presentation
Capturing using a web camera of the remote computer system video data of the player, wherein the video data captures eye movements of the player while the display of the remote computer system is displaying to the player the first static image and the second static image.
Edited video creation from a two-dimensional area of interest
Creating edited video data from a subset of the video data in response to a pre-defined two dimensional area of interest from the video data, wherein the edited video data has a lower resolution than the video data.
Host-side view-time measurement and viewing relationship determination
Determining with the host computer a first amount of time representing an amount of time the player views the first static image and a second amount of time representing an amount of time the player views the second static image, in response to the edited video data; and determining with the host computer a viewing relationship for the player between the second amount of time and the first amount of time, in response to the first amount of time and the second amount of time.
Threshold-based success flag and success indication feedback
Determining with the host computer whether the viewing relationship exceeds a first threshold and generating a success flag in response thereto; and providing from the host computer to the remote computer system an indication that the player is successful, in response to the success flag.
Across the identified independent claim, the core coverage ties together remote timed presentation of first and second static images, web-camera eye-movement video capture, lower-resolution edited video generation from a pre-defined two-dimensional area of interest, host-side determination of view times and a viewing relationship, and threshold evaluation to generate a success flag and provide a success indication back to the remote system.
