Toolkit support for interactive projected displays

Interactive projected displays are an emerging class of computer interface with the potential to transform interactions with surfaces in physical environments. They distinguish themselves from other visual output technologies, for instance LCD screens, by overlaying content onto the physical world. They can appear, disappear, and reconfigure themselves to suit a range of application scenarios, physical settings, and user needs. These properties have attracted significant academic research interest, yet the surrounding technical challenges and lack of application developer tools limit adoption to those with advanced technical skills. These barriers prevent people with different expertise from engaging, iteratively evaluating deployments, and thus building a strong community understanding of the technology in context. We argue that creating and deploying interactive projected displays should take hours, not weeks. This thesis addresses these difficulties through the construction of a toolkit that effectively facilitates user innovation with interactive projected displays. The toolkit’s design is informed by a review of related work and a series of in-depth research probes that study different application scenarios. These findings result in toolkit requirements that are then integrated into a cohesive design and implementation. This implementation is evaluated to determine its strengths, limitations, and effectiveness at facilitating the development of applied interactive projected displays. The toolkit is released to support users in the real-world and its adoption studied. The findings describe a range of real application scenarios, case studies, and increase academic understanding of applied interactive projected display toolkits. By significantly lowering the complexity, time, and skills required to develop and deploy interactive projected displays, a diverse community of over 2,000 individual users have applied the toolkit to their own projects. Widespread adoption beyond the computer-science academic community will continue to stimulate an exciting new wave of interactive projected display applications that transfer computing functionality into physical spaces

Tune your brown clustering, please

Brown clustering, an unsupervised hierarchical clustering technique based on ngram mutual information, has proven useful in many NLP applications. However, most uses of Brown clustering employ the same default configuration; the appropriateness of this configuration has gone predominantly unexplored. Accordingly, we present information for practitioners on the behaviour of Brown clustering in order to assist hyper-parametre tuning, in the form of a theoretical model of Brown clustering utility. This model is then evaluated empirically in two sequence labelling tasks over two text types. We explore the dynamic between the input corpus size, chosen number of classes, and quality of the resulting clusters, which has an impact for any approach using Brown clustering. In every scenario that we examine, our results reveal that the values most commonly used for the clustering are sub-optimal

Congress UPV Proceedings of the 21ST International Conference on Science and Technology Indicators

This is the book of proceedings of the 21st Science and Technology Indicators Conference that took place in València (Spain) from 14th to 16th of September 2016. The conference theme for this year, ‘Peripheries, frontiers and beyond’ aimed to study the development and use of Science, Technology and Innovation indicators in spaces that have not been the focus of current indicator development, for example, in the Global South, or the Social Sciences and Humanities. The exploration to the margins and beyond proposed by the theme has brought to the STI Conference an interesting array of new contributors from a variety of fields and geographies. This year’s conference had a record 382 registered participants from 40 different countries, including 23 European, 9 American, 4 Asia-Pacific, 4 Africa and Near East. About 26% of participants came from outside of Europe. There were also many participants (17%) from organisations outside academia including governments (8%), businesses (5%), foundations (2%) and international organisations (2%). This is particularly important in a field that is practice-oriented. The chapters of the proceedings attest to the breadth of issues discussed. Infrastructure, benchmarking and use of innovation indicators, societal impact and mission oriented-research, mobility and careers, social sciences and the humanities, participation and culture, gender, and altmetrics, among others. We hope that the diversity of this Conference has fostered productive dialogues and synergistic ideas and made a contribution, small as it may be, to the development and use of indicators that, being more inclusive, will foster a more inclusive and fair world

The end of stigma? Understanding the dynamics of legitimisation in the context of TV series consumption

This research contributes to prior work on stigmatisation by looking at stigmatisation and legitimisation as social processes in the context of TV series consumption. Using in-depth interviews, we show that the dynamics of legitimisation are complex and accompanied by the reproduction of existing stigmas and creation of new stigmas
