Abstract
An apparatus for the management of time during a visual presentation such as a talk with slides includes an optical emitter surface and focusing assembly for presentation of a progress plot in circular or linear format onto a presentation display shared by a presentation image. A user interface with policies and rules is operative with a controller for an optical emitter to automatically provide and adjust the brightness and contrast level, select optimal regions for placement of the progress image, and generate the optical image which is displayed in superposition with, or adjacent to, the presentation image.
