Many computer operating systems provide seamless support for multiple display screens, but there are few cross-platform tools for collaborative use of multiple computers in a shared display environment. Mighty Mouse is a novel groupware tool built on the public domain VNC protocol. It is tailored specifically for face-to-face collaboration where multiple(More)
The effectiveness of interaction with mobile devices can be impacted by handedness; however, support for handedness in the interface is rarely provided. The goal of this article is to demonstrate that handedness is a significant interface consideration that should not be overlooked. Four studies were conducted to explore left-handed user interaction with(More)
Mobile devices have been used as tools for navigation and geographic information retrieval with some success. However, screen size, glare, and the cognitive demands of the interface are often cited as weaknesses when compared with traditional tools such as paper maps and guidebooks. In this paper, a simple mixed media approach is presented which tries to(More)
This study tested whether multiple-object tracking-the ability to visually index objects on the basis of their spatiotemporal history-is scene based or image based. Initial experiments showed equivalent tracking accuracy for objects in 2-D and 3-D motion. Subsequent experiments manipulated the speeds of objects independent of the speed of the scene as a(More)
Enabling group collaboration is important in computer graphics today. We have developed a framework that supports multiple pointing devices to explore the collaborative utility of multiple mice and laser pointer interaction in graphical environments. Because most pointing device comparisons are done in the context of single user performance, very little is(More)
