Digital immersion is moving into public space. Interactive screens and public displays are deployed in urban environments, malls, and shop windows. Inner city areas, airports, train stations and stadiums are experiencing a transformation from traditional to digital displays enabling new forms of multimedia presentation and new user experiences. Imagine a(More)
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)
In this paper we show how audience expectations towards what is presented on public displays can correlate with their attention towards these displays. Similar to the effect of Banner Blindness on the Web, displays for which users expect uninteresting content (e.g. advertisements) are often ignored. We investigate this effect in two studies. In the first,(More)
Non-planar screens, such as columns, have been a popular means for displaying information for a long time. In con-trast to traditional displays their digital counterparts are mainly flat and rectangular due to current technological constraints. However, we envision bendable displays to be available in the future, which will allow for creating new forms of(More)
We present Communiplay, a public display media space. People passing by see their own contour mirrored on a public display and can start to play with virtual objects. At the same time, they see others playing at remote displays within the same virtual space. We are interested whether people would use such a public display media space, and if so, how and(More)
After years in the lab, interactive public displays are finding their way into public spaces, shop windows, and public institutions. They are equipped with a multitude of sensors as well as (multi-) touch surfaces allowing not only the audience to be sensed, but also their effectiveness to be measured. The lack of generally accepted design guidelines for(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 ReflectiveSigns, i.e. digital signage (public electronic displays) that automatically learns the audience preferences for certain content in different contexts and presents content accordingly. Initially, content (videos, images and news) are presented in a random manner. Using cameras installed on the signs, the system observes the(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)
