Papers/Notes: Interfaces and Visualization

Monday, April 12
2:30 PM - 4:00 PM

 Occlusion-Aware Interfaces
Daniel Vogel, University of Toronto, Mount Allison University, Canada
Ravin Balakrishnan, University of Toronto, Canada

Describes an interaction technique to reduce the effect of hand occlusion with pen input using image processing and a configurable occlusion model. Can assist researchers in designing other occlusion-aware techniques.

High-Precision Magnification Lenses
Caroline Appert, LRI - Université Paris-Sud et CNRS, INRIA, France
Olivier Chapuis, LRI - Université Paris-Sud et CNRS, INRIA, France
Emmanuel Pietriga, INRIA, LRI - Université Paris-Sud et CNRS , France

Presents and evaluates new magnification lenses that allow both fast navigation and high-precision by addressing the mismatch between visual space and motor space in the magnified region.

Quasi-Qwerty Soft Keyboard Optimization
Xiaojun Bi, University of Toronto IBM Research - Almaden, Canada
Barton Smith, IBM Research - Almaden, USA
Shumin Zhai, IBM Research - Almaden, USA

By moving letters at most one key away from original positions on Qwerty, Quasi-Qwerty reduces novice user's visual search time over freely optimized layout and improves inputting speed over Qwerty.
