A New Approach for Slideshow Presentation at Working Meetings

Today, presentations at most working meetings are supported by computer slides. The traditional approach is to display the slides with a projector. A less traditional approach follows from research into interactive rooms, where presentations can be carried out with the help of multiple, typically embedded displays. This paper explores a third approach that is motivated by a simple observation – nowadays people often bring into meetings their own laptops, which are capable of supporting slideshow applications and can internetwork with other devices. We present DiS, a proof-ofconcept application that implements this approach building on existing slideshow software and on network and distributed system protocols. We perform a comparative evaluation of our application with related work, focusing on two parameters: network traffic and visual responsiveness.
