Papers/Notes: Speech and Touch

Monday, April 12
4:30 PM - 6:00 PM

FingerCloud: Uncertainty and autonomy handover in capactive sensing
Simon Rogers, University of Glasgow, UK
John Williamson, University of Glasgow, UK
Craig Stewart, University of Glasgow, UK
Rod Murray-Smith, University of Glasgow, UK

Probabilistic filters are used for robust finger tracking over capacitive arrays on handheld devices, and we show how uncertainty from such sensing can be used in interaction design.

The Generalized Perceived Input Point Model and How to Double Touch Accuracy by Extracting Fingerprints
Christian Holz, Hasso Plattner Institute, Germany
Patrick Baudisch, Hasso Plattner Institute, Germany

Proposes a new model explaining the inaccuracy of touch input. Shows how to exploit the model to create highly precise touch input devices.

Finger-Count & Radial-Stroke Shortcuts: 2 Techniques for Augmenting Linear Menus on Multi-Touch Surfaces
Gilles Bailly, Telecom ParisTech, France
Eric Lecolinet, Telecom ParisTech, France
Yves Guiard, Telecom ParisTech, France

We present and evaluate Finger-Count and Radial-Stroke Shortcuts, two multi-finger two-handed interaction techniques aimed at augmenting the menubar on multi-touch surfaces, while maintaining compatibility with traditional interaction techniques.

Speech Dasher: Fast Writing using Speech and Gaze
Keith Vertanen, University of Cambridge, UK
David J.C. MacKay, University of Cambridge, UK

Speech Dasher allows writing using speech and a zooming interface. Users speak what they want to write and then navigate through the space of recognition hypotheses to correct errors.
