Dynamic graphical user interface generation for web-based public display applications

Public digital displays are moving towards open display networks, resulting in a shift in the focus from single-purpose public displays that are developed with a single task or application in mind, to general- purpose displays that can run several applications, developed by different vendors. In this new paradigm, it is important to facilitate the development of interactive public display applications and provide programmers with toolkits for incorporating interaction features. An important function of such toolkits is to support interaction with public displays through a users' smartphone, allowing users to discover and interact with the public display applications configured in a given display. This paper describes our approach to providing dynamically generated graphical user interfaces for public display applications that is part of the PuReWidgets toolkit
