Papers/Notes: Pointing and Selecting

Tuesday, April 13
9:00 AM - 10:30 AM

 Why it's Quick to be Square: Modelling New and Existing Hierarchical Menu Designs
David Ahlström, Klagenfurt University, Austria
Andy Cockburn, University of Canterbury, New Zealand
Carl Gutwin, University of Saskatchewan, Canada
Pourang Irani, University of Manitoba, Canada

Describes a model that predicts performance with hierarchical menus. Empirically validates the model with various designs, including a novel SquareMenu. Demonstrates how modelling can motivate new designs and explain performance.

pCubee: A Perspective-Corrected Handheld Cubic Display
Ian Stavness, University of British Columbia, Canada
Billy Lam, University of British Columbia, Canada
Sidney Fels, University of British Columbia, Canada

Describes a handheld cubic display system made with five flat-panel screens that uses perspective-corrected rendering and real-time physics simulation to create compelling visualization and interaction techniques for 3D content.

Bias towards Regular Configuration in 2D Pointing
Huahai Yang, IBM Research - Almaden, USA
Xianggang Xu, Civil Aviation Medical Center, China

Introduce the framework of configuration space as a way of understanding HCI tasks. Show that 2D pointing task performance reflects a bias towards a regular configuration.
