Interactive Out-of-home Displays
In my dissertation I investigated passer-by and audience behavior around differently shaped large interactive displays in public space such as a round interactive advertising column, a long interactive banner display and an interactive life-size screen. These interactive public displays become more active themselves to attract passer-by attention, to convey their interactivity and to actively influence passer-by behavior in order to improve the public interaction in front of them. The results of this work have been presented at CHI and DIS.
Interactive Advertising Column
To explore how passers-by notice and behave around interactive columns in public space we conducted several studies with the Interactive Advertising Column which was equipped with 8 Kinect sensors to realize a seamless interaction space around the column. In one field study of five weeks in public space we investigated how passers-by would notice the interactivity of the column, if they would position themselves differently around the seamless column compared to framed columns, as well as the movement patterns and the social and performative interaction around the column.
Interactive Banner Display
To explore how passers-by would notice interactivity when passing by public displays sideways we conducted several studies with a long Interactive Banner Display that we installed at a sidewalk in Munich and equipped with Kinect sensors. In one field study of six weeks we explored how the long display could attract attention and communicate its interactivity by different types of visual feedback when passers-by approach sideways. For comparison, we also conducted a field study of how, in an opposite situation, a portrait-ratio life-size display that passersby approached frontally could convey its interactivity.
The Puppeteer Display
In this work we explored how interactive public displays can become more active themselves and actively influence passer-by behavior in front of them in order to improve the interactive experience. To overcome the challenge that larger groups of passers-by often crowd together in front of wide public displays or do not take optimal positions for interaction, this work presented a solution to subtly and actively guide users by dynamic and interactive visual cues on the screen in order to better distribute them. In a field study of five weeks we observed that users positioned themselves in front of the visual cues and followed them when they moved, so that the display was able to guide users to empty spots, dissolve crowds and distribute users to improve parallel usage, and influence the social constellations in front of it.
