Patent ID: 8108800

Claim:
A computer-implemented method for generating a cognitive efficiency score of a page derived from eye fixation data for a page, the method comprising steps of: dividing eye fixation data for a first page into a grid; determining a number of eye fixations for each grid element of the eye fixation data; establishing a threshold number of fixations above which a grid element is deemed to be seen; establishing a threshold number of fixations above which a grid element is deemed to be noticed; counting a number of seen grid elements and a number of noticed grid elements in said eye fixation data for said first page; and producing a first cognitive efficiency score of said first page based in part on of the number of seen grid elements and the number of noticed grid elements wherein the step of producing said first cognitive efficiency score includes computing a ratio of the number of seen grid elements to the number of noticed grid elements; producing a second cognitive efficiency score of a second page based in part on a number of seen grid elements and a number of noticed grid elements on the second page; wherein said second page contains the same information as said first page but is designed differently than said first page; wherein the steps are performed by one or more computing devices.
