In this paper, we describe the use of a tiled-display wall platform for use as a general purpose collaboration and learning platform. The main scenario of emphasis for this work is online learning by users in different countries. We describe the general efficacy of this platform for our purposes and describe its shortcomings for this purpose empirically. We discuss its advantages and also the shortcomings that we found. We also describe an enhancement made to make it more viable for our target usage scenario by implementing an interface for a modern human interface device. Copyright 2009 ACM.
