In this project, we looked at how to design presentation software for very large surfaces or multiple screens. We first observed how instructors use traditional visual aids such as blackboards and large whiteboard surfaces. This helped us understand the benefits of using large spaces for instructing. Based on these understandings, we designed and implemented MultiPresenter. MultiPresenter is a multi-screen presentation software that enables presenters to make use of the multiple screens available in many conference and lecture halls today. It provides instructors with the ability to dynamically choose during the presentation what slides or parts of slides are important to be kept persistent for longer use. It also allows presenters to build premade multiple screen presentation.
