Issues concerning web-based business reporting: an analysis of the views of interested parties

Rapid developments in information and communications technology have led organisations in many countries to consider the impact of the Internet on the delivery and dissemination of business information. This paper reports the findings of a UK study into the views of various user groups, preparers and auditors regarding specific proposals for change and newly emerging practices. Over 500 individuals from six groups responded to a questionnaire study, representing an overall response rate of 33%. Views were elicited regarding: (i) the desirability of different kinds of additional information that could be provided electronically, (ii) the usefulness of different navigation and search aids, and (iii) the portability of information under different formats.It is found that users favour many of the expansions of scope made possible by the web. A range of navigation aids, search aids and file formats are found by all groups to be at least fairly useful, especially global navigation aids. Preferences regarding file formats vary across the groups. Paired group comparisons show that, while expert and non-expert users hold similar views in relation to many issues, users' and preparers' views differ considerably. Auditors' views generally fall in between those of users and preparers. Cyert and Ijiri's (1974) framework is used to rationalise the observed conflicts and congruences of interest, underpinning clear pointers for policy-makers

Non-visual overviews of complex data sets

This paper describes the design and preliminary testing of an interface to obtain overview information from complex numerical data tables non-visually, which is something that cannot be done with currently available accessibility tools for the blind and visually impaired users. A sonification technique that hides detail in the data and highlights its main features without doing any computations to the data, is combined with a graphics tablet for focus+context interactive navigation, in an interface called TableVis. Results from its evaluation suggest that this technique can deliver better scores than speech in time to answer overview questions, correctness of the answers and subjective workload

Feeling what you hear: tactile feedback for navigation of audio graphs

Access to digitally stored numerical data is currently very limited for sight impaired people. Graphs and visualizations are often used to analyze relationships between numerical data, but the current methods of accessing them are highly visually mediated. Representing data using audio feedback is a common method of making data more accessible, but methods of navigating and accessing the data are often serial in nature and laborious. Tactile or haptic displays could be used to provide additional feedback to support a point-and-click type interaction for the visually impaired. A requirements capture conducted with sight impaired computer users produced a review of current accessibility technologies, and guidelines were extracted for using tactile feedback to aid navigation. The results of a qualitative evaluation with a prototype interface are also presented. Providing an absolute position input device and tactile feedback allowed the users to explore the graph using tactile and proprioceptive cues in a manner analogous to point-and-click techniques

SeeResults: A Spreadsheet Application for the Analysis of CGE Model Results

CGE models tend to produce large amounts of result data, and it can be difficult and timeconsuming to view, import, process and keep track of these. SeeResults is an Excel-based spreadsheet application that has been developed within the PROVIDE project to facilitate viewing results and producing presentation output, such as charts. It effectively functions as a GDX (a binary format used for output from GAMS) file viewer, and has been designed to be flexible, user-friendly and immediately usable with minimal configuration. This paper describes the rationale for the application, its main features, a number of screen captures and implementation notes.Research and Development/Tech Change/Emerging Technologies,

Towards an Interaction-based Integration of MKM Services into End-User Applications

The Semantic Alliance (SAlly) Framework, first presented at MKM 2012, allows integration of Mathematical Knowledge Management services into typical applications and end-user workflows. From an architecture allowing invasion of spreadsheet programs, it grew into a middle-ware connecting spreadsheet, CAD, text and image processing environments with MKM services. The architecture presented in the original paper proved to be quite resilient as it is still used today with only minor changes. This paper explores extensibility challenges we have encountered in the process of developing new services and maintaining the plugins invading end-user applications. After an analysis of the underlying problems, I present an augmented version of the SAlly architecture that addresses these issues and opens new opportunities for document type agnostic MKM services.Comment: 14 pages, 7 figure

Initial report on Object Spreadsheets

There is a growing demand for data-driven web applications that help automate organizational and business processes of low to medium complexity by letting users view and update structured data in controlled ways. We present Object Spreadsheets, an end-user development tool that combines a spreadsheet interface with a rich data model to help the process administrators build the logic for such applications themselves. Its all-in-one interface with immediate feedback has the potential to bring more complex tasks within reach of end-user developers, compared to existing approaches. Our data model is based on the structure of entity-relationship models and directly supports nested variable-size collections and object references, which are common in web applications but poorly accommodated by traditional spreadsheets. Object Spreadsheets has a formula language suited to the data model and supports stored procedures to specify the forms of updates that application users may make. Formulas can be used to assemble data in the exact structure in which it is to be shown in the application UI, simplifying the task of UI building; we intend for Object Spreadsheets to be integrated with a UI builder to provide a complete solution for application development. We describe our prototype implementation and several example applications we built to demonstrate the applicability of the tool

Development of Distributed Research Center for analysis of regional climatic and environmental changes

We present an approach and first results of a collaborative project being carried out by a joint team of researchers from the Institute of Monitoring of Climatic and Ecological Systems, Russia and Earth Systems Research Center UNH, USA. Its main objective is development of a hardware and software platform prototype of a Distributed Research Center (DRC) for monitoring and projecting of regional climatic and environmental changes in the Northern extratropical areas. The DRC should provide the specialists working in climate related sciences and decision-makers with accurate and detailed climatic characteristics for the selected area and reliable and affordable tools for their in-depth statistical analysis and studies of the effects of climate change. Within the framework of the project, new approaches to cloud processing and analysis of large geospatial datasets (big geospatial data) inherent to climate change studies are developed and deployed on technical platforms of both institutions. We discuss here the state of the art in this domain, describe web based information-computational systems developed by the partners, justify the methods chosen to reach the project goal, and briefly list the results obtained so far

Memetic: from meeting memory to virtual ethnography & distributed video analysis

The JISC-funded Memetic2 project was designed as knowledge management and project memory support for teams meeting via the Access Grid environment (Buckingham Shum et al, 2006). This paper describes how these capabilities also enable it to serve as a novel distributed video analysis tool to support interaction analysis. Memetic technologies can be used to record, annotate and discuss sessions recorded within a flexible, visual hypermedia environment called Compendium. We propose that beyond the use originally conceived, the Memetic toolset could find wide ranging applications within social science for virtual ethnography and data analysis
