Abstract Current eye-typing systems are suffering from the needed dwell timeout which limits the possible entry rate. In this position paper we discuss how the usage of eye-traces on on-screen keyboards could be used for almost dwell timeout free gaze based communication. ...

This paper starts with the assertion that the way physical objects are currently transported, handled, stored, realized, supplied, and used throughout the world is unsustainable economically, environmentally, and socially. Evidence supporting this assertion is exposed through a set of key unsustainability symptoms. Then, the paper expresses the goal to revert this situation, thus meeting the gl...

R ecent technological advances have enabled the significant growth of cyberspace, which is transforming the way citizens, corporations, and governments interact, collaborate, and conduct business. At the same time, our heavy dependence on various digital infrastructures, including the Internet, has made them strategic national assets—like land, water, and airspace—that must be safeguarded to en...

In this chapter, we give an overview of what ontologies are and how they can be used. We discuss the impact of the expressiveness, the number of domain elements, the community size, the conceptual dynamics, and other variables on the feasibility of an ontology project. Then, we break down the general promise of ontologies of facilitating the exchange and usage of knowledge to six distinct techn...

Civic hackathons have become a popular, experimental process through which to promote public access to open government data and enable innovative civic uses for the information. The International Space Apps Challenge, led by NASA, is a high-profile event, promoting the use of space-derived data with the aim of contributing solutions to 'grand challenges' such as environmental sustainability. Ce...

1 This is one of a number of proposals being discussed in the framework of the UK 'Grand Challenges' initiative of the UK computing research committee (UKCRC).

This paper presents a grand challenge for Digital Archaeology of a different kind: it is not technical in and of itself, it does not seek out technological solutions for archaeological problems, it does not propose new digital tools or digital methodologies as such. Instead, it proposes a broader challenge, one which addresses the very stuff of archaeology: an understanding of how digital techn...
