In this paper we present our findings from a lab and a field study investigating how passers-by notice the interactivity of public displays. We designed an interactive installation that uses visual feedback to the incidental movements of passers-by to communicate its interactivity. In the field study, three displays were installed during three weeks in shop(More)
We investigate how to reveal an initial mid-air gesture on interactive public displays. This initial gesture can serve as gesture registration for advanced operations. We propose three strategies to reveal the initial gesture: spatial division, temporal division and integration. Spatial division permanently shows the gesture on a dedicated screen area.(More)
This paper presents Flower menu, a new type of Marking menu that does not only support straight, but also curved gestures for any of the 8 usual orientations. Flower menus make it possible to put many commands at each menu level and thus to create as large a hierarchy as needed for common applications. Indeed our informal analysis of menu breadth in popular(More)
When the user is engaged with a real-world task it can be inappropriate or difficult to use a smartphone. To address this concern, we developed ShoeSense, a wearable system consisting in part of a shoe-mounted depth sensor pointing upward at the wearer. ShoeSense recognizes relaxed and discreet as well as large and demonstrative hand gestures. In(More)
We propose Radial-Stroke and Finger-Count Shortcuts, two techniques aimed at augmenting the menubar on multi-touch 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(More)
We propose iSkin, a novel class of skin-worn sensors for touch input on the body. iSkin is a very thin sensor overlay, made of biocompatible materials, and is flexible and stretchable. It can be produced in different shapes and sizes to suit various locations of the body such as the finger, forearm, or ear. Integrating capacitive and resistive touch(More)
This paper introduces a new model-constrained, data-driven method to generate prosody from metalinguistic information. We refer here to the general ability of intonation to demarcate speech units and convey information about the propositional and interactional functions of these units within the discourse. Our strong hypothesis are that (1) these functions(More)
Most interactive public displays currently rely on flat screens. This form factor impacts how users (1) notice the public display (2) develop motivation and (3) (socially) interact with the public display. In this paper, we present <i>Chained Displays</i>, a combination of several screens to create different form factors for interactive public displays. We(More)
Distant displays such as interactive Public Displays (IPD) or Interactive Television (ITV) require new interaction techniques as traditional input devices may be limited or missing in these contexts. Free hand interaction, as sensed with computer vision techniques, presents a promising interaction technique. This paper presents the adaptation of three menu(More)
