Social NUI: social perspectives in natural user interfaces

Abstract: Natural User Interfaces (NUI) offer rich ways for interacting with the digital world that make innovative use of existing human capabilities. They include and often combine different input modalities such as voice, gesture, eye gaze, body interactions, touch and touchless interactions. However much of the focus of NUI research and development has been on enhancing the experience of individuals interacting with technology. Effective NUIs must also acknowledge our innately social characteristics, and support how we communicate with each other, play together, learn together and collaboratively work together. This workshop concerns the social aspects of NUI. The workshop seeks to better understand the social uses and applications of these new NUI technologies -- how we design these technologies for new social practices and how we understand the use of these technologies in key social contexts.

Multi-structured redundancy

Abstract: One-size-fits-all solutions have not worked well in storage systems. This is true in the enterprise where noSQL, Map-Reduce and column-stores have added value to traditional database workloads. This is also true outside the enterprise. A recent paper [7] illustrated that even the single-desktop store is a rich mixture of file systems, databases and key-value stores. Yet, in research one-size-fits-all solutions are always tempting and point-optimizations emerge, with the current theme du jour being key-value stores [8]. Workloads naturally change their requirements over time (e.g., from update-intensive to query-intensive). This paper proposes research around a multistructured storage architecture. Such architecture is composed of many lightweight data structures such as BTrees, key-value stores, graph stores and chunk stores. The call for modular storage and systems is not dissimilar to the Ex-okernel [4] or Anvil [10] approaches. The key difference that this paper argues about is that we want these data structures to co-exist in the same system. The system should then automatically use the right one at the right workload phase. To enable this technically, we propose to leverage the existing N-way redundancy in the data center and have each of N replicas embody a different data structure.

Controlling a telecommunications device

Abstract: A telecommunications device comprises a communication alert system arranged to inform the user that a telecommunications signal has been received. The communication alert system uses one of a number of different indicators. The controller is arranged to control the selection of the one of a plurality of indicators such that the selection is affected by a user selectable component of the received telecommunications signal.

스크린 위의 삶 = Life on the screen : identity in the age of the internet

Abstract: From the Publisher: A Question of Identity Life on the Screen is a fascinating and wide-ranging investigation of the impact of computers and networking on society, peoples' perceptions of themselves, and the individual's relationship to machines. Sherry Turkle, a Professor of the Sociology of Science at MIT and a licensed psychologist, uses Internet MUDs (multi-user domains, or in older gaming parlance multi-user dungeons) as a launching pad for explorations of software design, user interfaces, simulation, artificial intelligence, artificial life, agents, "bots," virtual reality, and "the on-line way of life." Turkle's discussion of postmodernism is particularly enlightening. She shows how postmodern concepts in art, architecture, and ethics are related to concrete topics much closer to home, for example AI research (Minsky's "Society of Mind") and even MUDs (exemplified by students with X-window terminals who are doing homework in one window and simultaneously playing out several different roles in the same MUD in other windows). Those of you who have (like me) been turned off by the shallow, pretentious, meaningless paintings and sculptures that litter our museums of modern art may have a different perspective after hearing what Turkle has to say. This is a psychoanalytical book, not a technical one. However, software developers and engineers will find it highly accessible because of the depth of the author's technical understanding and credibility. Unlike most other authors in this genre, Turkle does not constantly jar the technically-literate reader with blatant errors or bogus assertions about how things work. Although I personally don't have time or patience for MUDs,view most of AI as snake-oil, and abhor postmodern architecture, I thought the time spent reading this book was an extremely good investment.
