We put together a poster discussing some of our recent work on mobile displays for HotMobile. While presenting the poster I got a number of interesting ideas and concerns. One idea is to widening the idea of advertsing and fuse it with traditional classify ads by private people (e.g. advertising a flat or telling the world that you lost your cat). The big question is really how to measure audince exposure and eventually conversion. There are several ideas how to do this – but looks more like another master project on the topic than a overnight hack
The abstract for the poster:
In recent years many conventional public displays were replaced by electronic displays hence enabling novel forms of advertising and information dissemination. This includes mainly stationary displays, e.g. in billboards and street furniture, and currently first mobile displays on cars appear. Yet, current approaches are mostly static since they neither do consider mobility and the context they are used in nor the context of the viewer. In our work we explore how mobile public displays, which rapidly change their own context, can gather and process information about their context. Data about location, time, weather, and people in the vicinity can be used to react accordingly by displaying related content such as information or advertisements.
When spending some time in Montain View I was suprised how few electronic screens I saw compared to Germany or Asia. But nevertheless they have their own ways of creating attention… see the video below
Some time back in Munich we look at how interaction modalities can effect the attention of bystanders, see  for a short overview of the work.
