Exploiting rules and processes for increasing flexibility in service composition

Recent trends in the use of service oriented architecture for designing, developing, managing, and using distributed applications have resulted in an increasing number of independently developed and physically distributed services. These services can be discovered, selected and composed to develop new applications and to meet emerging user requirements. Service composition is generally defined on the basis of business processes in which the underlying composition logic is guided by specifying control and data flows through Web service interfaces. User demands as well as the services themselves may change over time, which leads to replacing or adjusting the composition logic of previously defined processes. Coping with change is still one of the fundamental problems in current process based composition approaches. In this paper, we exploit declarative and imperative design styles to achieve better flexibility in service composition

Typothesis: A Study of Warde\u27s Crystal Goblet, Leeuwen\u27s Typographic Meaning and How it Relates to the Bible

The way readers interpret the written word is changing. We look for information almost as much in between the lines as we do in the words themselves. The internet and its tools offer ways for readers to engage the text like never before — can the printed word keep up? This thesis will look at the history of print through the eyes of typography and decide if multimodal methods of arranging type are appropriate or even possible in the modern book. Specifically, it will look at the Christian Bible and it’s already present use of multimodalism. This study will bring awareness to the possibility for a new method of meaning in Biblical typography

A protocol study of novice interaction design behaviour in Botswana: solution-driven interaction design

Think aloud studies and protocol analysis are well-known in the field of HCI, but most often these studies focus on usability evaluations, or on the use of technology. Rarely are they used to investigate the behaviour of interaction designers. In this paper, we report on a protocol study with novice interaction designers in Botswana. Participants had just completed the design section of an undergraduate module on Interaction Design that actively promotes a problem-driven approach to the design of interactive products, yet the participants behaved in a way that is closer to a solution-driven approach. The module emphasizes user-centred design, prototyping methods to support design development, and evaluating design detail. Yet participants suggest solutions before exploring the context of use, use prototyping methods to capture, rather than to develop, designs, and do not produce detailed designs. In a problem-solving context, some of these behaviours are typical of novices, but in a design context they are also seen in experienced designers. The results presented here reveal the detail of the approach adopted by these students, and contribute to the wider debate concerning the internationalization of HCI education

Issues in conducting expert validation and review and user evaluation of the technology enhanced interaction framework and method

A Technology Enhanced Interaction Framework has been developed to support designers and developers design and develop technology enhanced interactions for complex scenarios involving disabled people. Issues of motivation, time, and understanding when validating and evaluating the Technology Enhanced Interaction Framework were identified through a literature review and questionnaires and interviews with experts. Changes to content, system, and approach were made in order to address the identified issues. Future work will involve detailed analysis of the expert review and validation findings and the implementation of a motivating approach to user evaluation

Co-evolving problems and solutions: The case of novice interaction designers in Botswana and the UK

This paper establishes that problem-solution co-evolution is observed in novice interaction designers in the UK and Botswana. However, in the majority of Botswana protocols we could see a new type of co-evolution, which we termed solution-problem co-evolution. Solution- problem co-evolution uses ‘off the shelf’’ solutions to structure the problem space. Both types of co-evolution are described and discussed in this paper. The findings are drawn from the analysis of 18 (5 UK, 13 Botswana) 1-hour design protocols from two cohorts of students studying the same undergraduate Open University Interaction Design module, one in Botswana and one in the UK. Participants were required to complete a medical interaction design task under controlled conditions. We based our analysis on a coding scheme that was developed specifically for this protocol study. The coding scheme is based on Schön’s seminal work on reflective practice. It visually represents activities in the problem and solutions spaces

Investigative Designing: usage-oriented research in and through designing

In this paper, we discuss the practice of investigative designing. The notion is currently being used to denote a variety of ideas in design research, and we first seek to clarify some of them. We then present our own, specific take on this notion, while acknowledging that it is being used broadly. We adopted the notion as an umbrella term for our combined research and design activities: as investigative designers. We use it for the exploration of how designers can integrate designing and researching within a design process. The two main concerns we are pursuing within this are to clarify the role of a designer with research skills, and to explore the implications of a usage orientation in design. We present two studies in this paper in which we investigated how usage research for design can be specifically geared to the needs of design, and what helps designers (and what does not) in designing with usage information. In the first study, we ourselves conducted usage research, developed design ideas on the basis of that, and reflected on this process. In the second study, we observed how three other designers engaged with the same user data and developed design ideas. Our findings include that the designers tended to prefer to develop their own design ideas independently from the data, only checking or adapting the ideas to the data. Furthermore, the capacity of designers for dealing with data needs to be taken into consideration. Lastly, the form of data presentation influences how well designers can engage with it in designing.

Natural Notation for the Domestic Internet of Things

This study explores the use of natural language to give instructions that might be interpreted by Internet of Things (IoT) devices in a domestic `smart home' environment. We start from the proposition that reminders can be considered as a type of end-user programming, in which the executed actions might be performed either by an automated agent or by the author of the reminder. We conducted an experiment in which people wrote sticky notes specifying future actions in their home. In different conditions, these notes were addressed to themselves, to others, or to a computer agent.We analyse the linguistic features and strategies that are used to achieve these tasks, including the use of graphical resources as an informal visual language. The findings provide a basis for design guidance related to end-user development for the Internet of Things.Comment: Proceedings of the 5th International symposium on End-User Development (IS-EUD), Madrid, Spain, May, 201
