TELESTRATOR SYSTEM

摘要

A telestrator system running on a computing platform enables a video clip rendering on the platform to be telestrated with graphic objects including lines, arrows, or shapes that are drawn by a user using gestures that are captured by a camera system. The user can provide voice commentary while drawing on the video clip which is captured by a microphone in an audio track. A user interface ("UI") is exposed that enables the user to scrub the video clip to a desired point at which to telestrate, provides drawing markers having different colors, and supports undo and clear capabilities to undo drawing strokes and clear all telestration drawings from the video clip. The telestrator system UI also exposes recording controls so that the user can record a video of the telestration session with the accompanying audio commentary which can then be saved and shared, for example, on a social network.
