Finger-Count & Radial-Stroke Shortcuts: Two Techniques for Augmenting Linear Menus on Multi-Touch Surfaces
نویسندگان
چکیده
We propose Radial-Stroke and Finger-Count Shortcuts, two techniques aimed at augmenting the menubar on multitouch surfaces. We designed these multi-finger two-handed interaction techniques in an attempt to overcome the limitations of direct pointing on interactive surfaces, while maintaining compatibility with traditional interaction techniques. While Radial-Stroke Shortcuts exploit the wellknown advantages of Radial Strokes, Finger-Count Shortcuts exploit multi-touch by simply counting the number of fingers of each hand in contact with the surface. We report the results of an experimental evaluation of our technique, focusing on expert-mode performance. FingerCount Shortcuts outperformed Radial-Stroke Shortcuts in terms of both easiness of learning and performance speed. Author

Leaf Menus: Linear Menus with Stroke Shortcuts for Small Handheld Devices
This paper presents Leaf menu, a new type of contextual linear menu that supports curved gesture shortcuts. By providing an alternative to keyboard shortcuts, the Leaf menus can be used for the selection of commands on tabletops, but its key benefit is its adequacy to small handheld touchscreen devices (PDA, Smartphone). Indeed Leaf menus define a compact and known layout inherited from linear ...
متن کاملFinger-count Shortcuts: a Novel Interaction Technique for Qgis
INTRODUCTION GIS continuously increase in complexity, more and more data are created as much features developed to treat them. On the user side, GIS software is now integrated in several processes such as emergency management. In this article, we study how novel Human-Computer Interaction (HCI) techniques can improve GIS usability, especially for making command selection easier and for enabling...
متن کاملDesign of Unimanual Multi-Finger Pie Menu Interaction
Context menus, most commonly the right click menu, are a traditional method of interaction when using a keyboard and mouse. Context menus make a subset of commands in the application quickly available to the user. However, on tabletop touchscreen computers, context menus have all but disappeared. In this paper, we investigate how to design context menus for efficient unimanual multi-touch use. ...
متن کاملUsing classification to determine the number of finger strokes on a multi-touch tactile device
On certain types of multi-touch touchpads, determining the number of finger stroke is a non-trivial problem. We investigate the application of several classification algorithms to this problem. Our experiments are based on a flat prototype of the spherical Touchglobe touchpad. We demonstrate that with a very short delay after the stroke, the number of touches can be determined by a Support Vect...
متن کامل2D similarity transformations on multi-touch surfaces
We present and comparatively evaluate two new object transformation techniques for multi-touch surfaces. Specifying complete two-dimensional similarity transformations requires a minimum of four degrees of freedom: two for position, one for rotation, and another for scaling. Many existing techniques for object transformation are designed to function with traditional input devices such as mice, ...
