Abstract
A video capturing a user facing a camera is received. An image of the video is analyzed to identify a marking object in the image. The image captures the marking object held by the user in between the user and the camera. A gesture performed by the user is detected using the marking object in a space between the user and the camera. A location associated with the marking object is marked including by overlaying a highlight of a portion of content virtually shared between the user and one or more other remote participants. The overlaid highlight of the portion of the content is provided to one or more other remote participants via a collaboration medium.
