Abstract: A system and method to present global and local context sensitive augmented content in accordance with multiple criteria, including one or more user's preferences, and present the augmented content via a transparent layer on top of the original content for less obtrusive and more efficient browsing, knowledge discovery and exploration experience. The original content remains visible to the user while the augmented content is being viewed or interacted with. The global context sensitive augmented content is generated using metrics based on the overall document or content being viewed, while the local context sensitive augmented content is generated using metrics based on the currently viewed or selected object within the document or content being viewed. Real-time and theme based augmentation are used to further enhance the user's experience.
