The standard Chord diagram, a radial layout, shows data elements in a circular fashion from one data source. In this paper, we propose an extension to the standard Chord diagram to show data elements from two heterogeneous data sources into one single diagram. The main Chord diagram is used for showing data elements and the relations between them from one data source, while we use an outer layer to show data elements from the second data source. The relationships between data elements from both data sources are shown through visual cues. The proposed solution uses space efficiently compared to using multiple diagrams in the scenarios of two heterogeneous data sources., Posters, Shah Rukh Humayoun and Likhitha Brahmadevara

In this position paper, we present our approach of utilizing mobile devices (i.e., mobile phones and tablets) for assisting engineers and experts in understanding and maintaining the factory pipelines. For this, we present a platform, called assistME, that is composed of three main components: the assistME Server, the assistME mobile infrastructure, and the co-assistME collaborative environment. In order to get full utilization of the assistME platform, we assume that an initial setup is made in the factory in such a way that it is equipped with different sensors to collect data about specific events in the factory pipeline together with the corresponding locations of these events. The assistME Server works as a central control unit in the platform and collects data from the installed sensors in the factory pipeline. In the case of any unexpected behavior or any critical situation in the factory pipeline, notification and other details are sent to the related group of engineers and experts through the assistME mobile app. Further, the co-assistME collaborative environment, equipped with a large shared screen and multiple mobile devices, helps the engineers and experts to collaborate with to understand and analyze the current situation in the factory pipeline in order to maintain it accurately., Comment: 7 pages, 3 figures, MOBILEng/2014/02

Popularity and affordability of mobile computers, especially tablets and smart phones, is considerably rising, providing an access capability for different user groups to various ICT services. Nevertheless, software solutions and hardware devices often seem not suitable enough for some target groups, like people with complex communication needs. In order to gain understanding of the challenges for usability and accessibility requirements gathering for ICT services for aided augmentative and alternative communication (AAC), this paper presents directions towards building usability requirements taxonomy for mobile AAC services. Analysis of influential factors for building proper requirements specification for an AAC service is given. Outlines for new paradigm of so-called augmentative requirements engineering (ARE) are presented, demanding holistic view on service requirements concerning users abilities and needs, service domain and associated intermediary users.
