Towards better support for collaborative research by using DUIs with mobile devices: SocialTV navigation design case study

Due to the increasing importance of usability and privacy evaluation (e.g., for SocialTV), an identi�ed challenge in our case is to support multi-disciplinary research activities related to it (e.g. rapid prototyping or interaction design evaluation) in a collaborative way. In this paper, we propose extending a collaborative system in order to exibly allow for react on change requirements with respect to realistic So- cialTV situations for di�erent research purposes (usability and privacy requirements identi�cation and evaluation etc.). Thereby a high-�delity prototype that remains exible for future extensions with reduced realization costs, becomes crucial. We concretely target this by means of a DUI based prototype that enables involved people to use their own mo- bile devices for navigation in a selected SocialTV scenario

Privacy and Security in Multi-modal User Interface Modeling for Social Media

This paper addresses privacy and security issues regarding the modeling of multi-modal user interfaces for social media applications. The proposed approach describes how privacy and security concerns are modeled from the user interface perspective, and how this model is related to a four layer conceptual framework for developing multi-modal and multi platform user interfaces. The approach also explains how to adapt these models to the development of social media applications. Finally, we use this proposal to model the Social TV case of study as an example of a social media application to show its feasibility

Using Distributed User Interfaces to Evaluate Decision Making in Cloud Deployment

In case of incidents in information technology (IT) systems of a supply chain participant, crisis teams need to quickly take steps in order to keep IT systems and therefore the supply chain running. Deploying an IT infrastructure partly or completely on cloud infrastructure is a viable solution, e.g. as in the face of technical failures and cyber attacks. Currently there is poor support of tools, which allow lay users for cloud deploying applications in a provider independent fashion and with respect to their individual security requirements. For this task we presented and discussed ESCAVISION. In this paper we propose an approach based on distributed user interfaces in order to evaluate the usability of ESCAVISION and the process of decision making in crisis teams. Furthermore the respective interaction design as well as the WallShare based infrastructure are described. We also discuss the approach and future directions

Model-Driven Privacy and Security in Multi-modal Social Media UIs

Model-driven approaches in software development are widely seen as a useful concept to a) support the formulation of non-functional requirements (NFRs) in a way domain experts are capable of, b) allow integration of multiple perspectives (from multiple domains) on the modeled system, and c) allow a stepwise refinement when actually realizing these models by a sequence of model transformations from high-, non-IT expert level down to a rather technical level. In this paper, the NFRs privacy and security are focused in the modeling of multi-modal user interfaces for social media applications. It is described how privacy and security concerns are modeled from the user interface perspective, and how this model is related to a four layer conceptual framework for developing multi-modal and multi-platform user interfaces. The approach also explains how to adapt these models to the development of social media applications. Finally, we use this proposal to model the SocialTV case study as an example of a social media application to show its feasibility

Multilocus Sequence Analysis of Close Relatives Vibrio anguillarum and Vibrio ordalii

The genetic heterogeneity of the close relatives Vibrio anguillarum and Vibrio ordalii, both serious pathogens of fish causing extensive losses in aquaculture, was studied. Eight housekeeping genes, i.e., atpA, ftsZ, gapA, gyrB, mreB, rpoA, topA, and pyrH, were partially sequenced in 116 isolates from diverse fish species and geographical areas. The eight genes appear to be under purifying selection, and the genetic diversity in the total data set was estimated to be 0.767 +/- 0.026. Our multilocus sequence analysis (MLSA) scheme identified several widespread clonal complexes and resolved the isolates, for the most part, according to serotype. Serotype O2b isolates from diseased cod in Norway, Ireland, and Scotland were found to be extremely homogeneous. Horizontal gene transfer appears to be fairly common within and between clonal complexes. Taken together, MLSA and in silico DNA-DNA hybridization (DDH) calculations suggest that some isolates previously characterized as V. ordalii, i.e., 12B09, FF93, FS144, and FS238, are in fact V. anguillarum isolates. The precise taxonomic situation for two isolates from Atlantic cod that display several traits consistent with V. ordalii, i.e., NVI 5286 and NVI 5918, and a single environmental strain that was previously considered to represent V. ordalii, i.e., FF167, is less clear
