General public sees these kinds of tiled video displays at best buy and think this is easy ...



Ability to show and interact with a single application / visualization across the entire surface

Ability to show and interact with multiple heterogeneous  applications / visualizations on the surface


Treating the wall like a big single desktop using a typical desktop OS

Running one copy of an application on a master node and distributing the graphics across all the screens

Running one copy of an application on each node and have them synchronize with each other

Running a custom desktop manager on each node that synchronize with each other as middleware



Issue for the tiled display versions - Do you take the borders into account and hide the imagery 'behind' them?  usually answer is yes, but not always




Some papers relevant to our work here in evl:

For Thursday's Class

If your UIN ends in an odd number you should read this paper and produce a similar 1 page report to show on the wall and perhaps discuss.

Lessons learned from the WILD room, a multisurface interactive environment
Michel Beaudouin-Lafon
IHM '11: 23rd French Speaking Conference on Human-Computer Interaction

If your UIN ends in an even number you should read this paper
and produce a similar 1 page report to show on the wall and perhaps discuss.
 
Effects of information layout, screen size, and field of view on user performance in information‐rich virtual environments
Nicholas F. Polys, Seonho Kim, Doug A. Bowman
VRST '05: Proceedings of the ACM symposium on Virtual reality software and technology, 2005
http://dl.acm.org/citation.cfm?id=1101626


Coming Next Week

Physiological Issues


Before next class please read

The Effects of Scene Complexity, Stereovision, and Motion Parallax on Size Constancy in a Virtual Environment
Luo, Kenyon, Kamper, Sandin, DeFanti
IEEE Virtual Reality 2007
http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=4161006

Again, you should produce a 1 page critique of the paper to put up on the wall Tuesday in class, and a subset of the students will be asked to talk more in depth about the paper.
