US Patent 10168771 User eye-gaze based derivation of activity stream processing augmentations

A content subject matter area of interest to a user is determined, using eye-gaze analysis of a user viewing existing activity stream content, according to content at a content location viewed by the user within the existing activity stream content. User-specific activity stream content augmentations are configured that are applicable to new activity stream content viewed by the user that includes the content subject matter area of interest to the user determined from the eye-gaze analysis. Using the configured user-specific activity stream content augmentations, portions of the new activity stream content viewed by the user determined to include the content subject matter area of interest to the user are augmented.
