Abstract: A method and apparatus for computing efficiency score of a page is provided and using the efficiency score to optimize page design. Eye tracking study is performed on a group of subjects where eye fixation data, gaze plot data, and qualitative information data are collected. Fixation information data for page is aggregated over the subjects in the study. The fixation information data is divided into a grid. Number of fixations is computed for every grid element. Seen and noticed thresholds are established for every grid element. Seen and noticed area of a page is computed by counting number of grid elements falling into either threshold. Ratio of area noticed over area seen is computed to yield efficiency score. Page fixation data are compared for alternate page designs. Areas of large difference are correlated with gaze plots and qualitative data to identify distinguishing features.

Abstract: Methods and apparatus are described for aggregating and presenting information in a network. A plurality of information sources relating to a category of subject matter are identified. Each information sources represents content from an associated site on the network. Each site has at least one parameter associated therewith representative of reliability with respect to the category. The content is periodically received from each of the plurality of information sources. The content received from the information sources via the network is indexed in a database. A portion of the content from the database is presented to a user via the network. The portion of the content corresponds to an index specified by the user.
