Understanding the use of web technologies for applications in open display networks

Abstract

Open display networks represent a new paradigm for large scale networks of public displays that are open to applications and content from third party sources. Web technologies may be particularly interesting as a technological framework for thirdparty application development in open display networks because of their portability and widespread use. However, there are also significant challenges involved that result from the specificities of this particular usage domain. In this work, we identify and characterize some of those specificities and analyze their implications for the use of web technologies. This contribution builds on our own experience with the development of multiple web-based applications for public displays and will inform the design of new models for this type of applications.

Application Diversity in Open Display Networks

“…With such displays, people experience a large number of applications and displays become an execution environment for dozens of interactive applications [17]. This raises a number of new research challenges that include technological issues, such as exploring the limitations and opportunities of web technologies for creating display applications [20] or understanding the extent to which application location impacts user experience when appropriating displays [7]. Cardoso et al [3] studied interaction abstractions for public display that allow developers to hide the complexity of managing various interaction techniques in order to provide display applications with interactive features.…”
