The presentation system can displaying indicia of such contacts, such as when a user writes with a fingertip, and can remove or alter such indicia responsive to other gestures and contacts. The system can accurately distinguish between types of gestures detected, such as between a writing gesture and an erasing gesture, on both large and small touch sensitive displays, thereby obviating the need for a user to make additional selective inputs to transition from one type of gesture to another. The system can determine how long to keep user annotations displayed during a presentation, based on the nature of the gesture used to make the annotations and the context in which they are made."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Context based annotating in an electronic presentation system","description":"A presentation system capable of detecting one or more gestures and contacts on a touch sensitive display.
