Easing Team Politics in Agile Usability: A Concept Mapping Approach
Found in: AGILE Conference
By Jeremy T. Barksdale, Eric D. Ragan, D. Scott McCrickard
Issue Date:August 2009
pp. 19-25
Team politics complicate software projects. They cause internal conflicts that can not only cost a software team time and money, but may also detract from the needs of the product’s end users. In this paper, we explore the use of concept maps as a means of...
 
The effects of navigational control and environmental detail on learning in 3D virtual environments
Found in: Virtual Reality Conference, IEEE
By Eric D. Ragan,Karl J. Huber,Bireswar Laha,Doug A. Bowman
Issue Date:March 2012
pp. 11-14
Studying what design features are necessary and effective for educational virtual environments (VEs), we focused on two design issues: level of environmental detail and method of navigation. In a controlled experiment, participants studied animal facts dis...
 
The effects of virtual character animation on spatial judgments
Found in: Virtual Reality Conference, IEEE
By Eric D. Ragan,Curtis Wilkes,Yong Cao,Doug A. Bowman
Issue Date:March 2012
pp. 141-142
Inaccurate perception of distances is a known problem within virtual environments. We hypothesize that the inclusion of virtual characters within these environments can improve an observer's ability to judge distances and achieve accurate spatial understan...
 
Questioning naturalism in 3D user interfaces
Found in: Communications of the ACM
By Doug A. Bowman, Eric D. Ragan, Ryan P. McMahan
Issue Date:September 2012
pp. 78-88
3D UIs are uniquely able to achieve superior interaction fidelity, and this naturalism can be a huge advantage.
     
The effects of spatial layout and view control on cognitive processing
Found in: Proceedings of the 2011 annual conference extended abstracts on Human factors in computing systems (CHI EA '11)
By Alex Endert, Doug A. Bowman, Eric D. Ragan, Francis Quek
Issue Date:May 2011
pp. 2005-2010
This study explores how spatial layout and view control impact learning. We performed a controlled experiment using a learning activity involving memory and comprehension of a visually represented story. We present our preliminary results comparing perform...
