Interactive visualisation for low literacy users

Sixteen percent (5.2 million) of the UK population possess low levels of literacy. The Government and other non-profit organisations, due to funding reforms, are forced to reduce the provision of face-to-face advice, and therefore, are pushing advice services via telephone or internet. As a consequence, low literacy users are experiencing difficulties finding the information they need to solve their day to day problems online. This thesis evaluates how walk in clients of a local Citizens Advice Bureau (CAB) who come to get social service information, obtain information online using the Adviceguide website. The thesis presents two challenges: (i) knowing the users in a way that can help consider design solutions that are probably not in a typical designer’s standard repertoire of design patterns, and (ii) knowing what is the problem that needs to be addressed. It is not simply an issue of usability or the need for simpler language, but understanding that these low literacy users are very different from the high literacy users. These low literacy users need this information to solve their day-to-day problems and are likely to be less successful in doing so. By providing an information architecture that permits them of a reasoning space and context, while supporting less abstract skills by visualized information in an unconventional way. The above challenges leave us with these research questions to address: what is the basis of such a design, how can these designs be incorporated into existing non-traditional interface proof of concept and finally how can these designs be evaluated

Applying visualisation to model-based formal specifications.

The most important and challenging activity in developing new software systems is arguably ascertaining their features and characteristics before development takes place. This activity, known as requirements engineering, involves software developers identifying the requirements of the customers who are procuring the system, and then documenting them in a requirements specification.Producing a requirements specification is a complex, time consuming and human-centred activity. It is essential that both parties discuss the requirements, analyse them and negotiate any issues, uncertainties or conflicts that arise. To assist in this process, a prototype of the software can be developed and then thrown away after the requirements process has been completed. Such a prototype helps to stimulate discussion and to provide a vehicle for experimentation and evaluation. This form of prototyping is now a popular and well-known requirements engineering technique. One powerful throwaway prototyping approach involves developing prototypes quickly using executable model-based formal specifications. These are based upon mathematical notations that possess a defined syntax and semantics. They have a useful dual role in the requirements process. On the one hand, they can be used to express requirements specifications in a precise and unambiguous manner, whilst on the other they can also be subjected to execution to produce a prototype. However, despite the benefits that such executable specifications have for the developer, their use can be problematic in situations that involve communication with customers. This is because traditionally, for reasons of productivity, the execution behaviour of prototypes developed in this manner is often depicted using developer-centred representations. Such representations often do not correspond to the perceptions or expertise of the customer, as they are often too abstract or technical. If the customer cannot recognise or comprehend these, accurate evaluation of the prototype cannot take place, stifling much needed dialogue and rendering the prototyping process ineffective.This research advocates that applying visualisation to this form of prototyping can alleviate the problems of comprehension and the subsequent breakdown in dialogue. The objective is to employ the techniques and principles of visualisation to transform the developer-centred prototype execution behaviour into customer-oriented representations based upon pictorial and graphical forms from their own universe of discourse. Applying visualisation in this way can retain the advantages of using executable formal specifications to build prototypes, while at the same time stimulating and sustaining effective dialogue between developers and customers. The objective of the research concerns the production of a system for visualising the execution of a specific executable formal specification-based prototype development technique. The resulting system is then evaluated by demonstrating its application in a series of case studies. These reveal the capabilities of the approach, and demonstrate the benefits that can be gained over and above the use of existing prototyping techniques based on executable formal specifications

A workbench to support development and maintenance of world-wide web

The World-Wide Web is one of the most dominant features of the Internet. In its short life it has become an important part of information technology, having a role to play in all sectors. Unfortunately, it has many problems too. Due to its fast evolution, World-Wide Web document development is undisciplined and has resulted in the appearance of much poor quality work. This is also widely due to the inexperience of authors, the lack of conventions, standards or guidelines and useful tools for development and maintenance of Web documents. One solution to the major problems of poor quality of World-Wide Web documents is the improved maintenance of such documents. Maintenance is an important area that, similar to software engineering, receives little attention compared with development. In order to address the problems of World-Wide Web document maintenance, research into the area was carried out through a literature survey and case studies of the organisations that manage World-Wide Web sites. The results of this research led to producing a workbench which provides support to both developers and maintainers of Web documents. This workbench consists of methods, guidelines and tools for World-Wide Web development and maintenance

Design, Design Thinking and Innovation: The Electrolux Professional Practices Assessment

The design thinking label assumed a plurality of minings since its first adoption in the design discipline and its subsequent developments in the management realm. Over its long journey, its different interpretations polarised the academic and practitioner audience eliciting appreciation and critiques. Today, the term coexists in different meanings. Still, both parties seem to agree on the positive impact of design thinking practices on organisations. Electrolux Professional is not an exception. Since the first adoption of the concept, the design department started to expand its influence, arriving to play a strategic role in the organisation’s innovation dynamics. The literature suggests a correlation between design thinking practices and innovation, but what are their real implications and impacts on the company’s innovation infrastructure? This research exploited the Electrolux Professional collaboration to investigate the design thinking practices in context. Firstly, it proposes a historical transdisciplinary interpretation of design thinking. Secondly, it focuses on the Electrolux Professional case, inquiring about its innovation ecosystem, the design department and the implication design thinking had. Thirdly, it describes the development of a multi-level framework and a correlated tool to explore the practices and perceived impacts. Finally, the framework was used to assess the design thinking practices in Electrolux Professional and develop three models summarising the primary characteristic of the design thinking practices. The last part aims to evaluate the design thinking impact on Electrolux Professional’s innovation system. Still, it is not concluded yet. The strategy is defined, and the monitoring system is being implemented, but data have not been collected yet. On the academic side, this study strived to reconnect design thinking with the design discipline, giving the designers and managers new evidence of its impact on innovation. On the practice side, the framework and the evaluation strategy aim to offer practitioners valuable tools to manage and leverage design and design thinking in the organisational innovation discussion.The design thinking label assumed a plurality of minings since its first adoption in the design discipline and its subsequent developments in the management realm.
