发明名称 System and method for electronic presentations having simultaneous display windows in a control screen
摘要 An electronic presentation system and method provides multiple display screens for presentation materials as well as permits dynamic annotations to presentation materials that do not permanently alter the presentation materials. The presentation materials can easily be directed to any one of the display screens and any annotations can be saved for future use or simply deleted. A single interface screen allows simple annotation of either the left or right screen images while a zoom feature allows slides to be presented in a variety of different ways.
