We present the design and evaluation of TapTap and MagStick, two thumb interaction techniques for target acquisition on mobile devices with small touch-screens. These two techniques address all the issues raised by the selection of targets with the thumb on small tactile screens: screen accessibility, visual occlusion and accuracy. A controlled experiment(More)
Despite the demonstrated benefits of bimanual interaction, most tablets use just one hand for interaction, to free the other for support. In a preliminary study, we identified five holds that permit simultaneous support and interaction, and noted that users frequently change position to combat fatigue. We then designed the BiTouch design space, which(More)
This article presents MaggLite, a toolkit and sketch-based interface builder allowing fast and interactive design of post-WIMP user interfaces. MaggLite improves design of advanced UIs thanks to its novel <i>mixed-graph</i> architecture that dynamically combines scene-graphs with interaction-graphs. <i>Scene-graphs</i> provide mechanisms to(More)
This paper presents a focus+context visualization and interaction technique for displaying large lists on handheld devices. This technique has been specifically designed to fit the constraints of small tactile screens. Thanks to its spiral layout, it provides a global view of large lists on a limited amount of screen real-estate. It has also been designed(More)
This paper presents Arpège, a progressive multitouch input technique for learning chords, as well as a robust recognizer and guidelines for building large chord vocabularies. Experiment one validated our design guidelines and suggests implications for designing vocabularies, i.e. users prefer relaxed to tense chords, chords with fewer fingers and(More)
We present a quick preview technique that smoothly transitions between document markup code and its visual rendering. This technique allows users to regularly check the code they are editing in-place, without leaving the text editor. This method can complement classical preview windows by offering rapid overviews of code-to-document mappings and leaving(More)
While interaction techniques that use the temporal dimension have been used for a long time, such as multiple clicks or spring-loaded widgets, more advanced uses of <i>rhythmic patterns</i> have received little attention in HCI. Using such temporal structures to convey information can be particularly useful in situations where the visual channel is(More)
This paper describes our methodology in providing designers with a new advanced 3D modeling Human-Computer Interaction. The main project – called GINA, a French acronym for Interactive and Natural Geometry – expect to introduce new intuitive and creative 3D modeling tools, relying on 2D perspective drawing reconstruction. We present here the user study we(More)
Pointing on large displays with an indirect, relative pointing device such as a touchpad often requires clutching. This article introduces <i>gliding</i>, where the cursor continues to move during the clutching gestures. The effect is that of controlling the cursor as a detached object that can be pushed, with inertia and friction similar to a puck being(More)
