Public digital displays have become increasingly ubiquitous in public and semi-public spaces. Most of them, however, do not support any interactive features, even though interaction is clearly recognized as a key element in making them more engaging and valuable. A key reason behind this apparent paradox is the lack of efficient and clear abstractions for incorporating interactivity into public display applications. While interaction can be achieved for a specific display system with a particular interaction modality, the lack of proper interaction abstractions means that there is too much specific work that needs to be done outside the core application functionality to support even basic forms of interaction. This is an effort that must be replicated by each developer, representing a wasted effort. This also leads to inconsistent interaction models across different displays and, as a result, people are not able to develop, based on previous experiences, any expectations and practices regarding their interaction with public displays.
In my PhD work, I’m addressing these issues and developing a toolkit that programmers can use to easily incorporate interactive features into their public display applications. This toolkit must address the specific requirements that the public display interaction environment imposes, namely the variety of possible interaction mechanism, the support for shared interactions that are expected to occur around the display, the specific life-cycle of public display applications, and the specific types of interactive controls that applications and users will require in this setting.
