A grammatical specification of human-computer dialogue

The Seeheim Model of human-computer interaction partitions an interactive application into a user-interface, a dialogue controller and the application itself. One of the formal techniques of implementing the dialogue controller is based on context-free grammars and automata. In this work, we modify an off-the-shelf compiler generator (YACC) to generate the dialogue controller. The dialogue controller is then integrated into the popular X-window system, to create an interactive-application generator. The actions of the user drive the automaton, which in turn controls the application

User Interface Management Systems: A Survey and a Proposed Design

The growth of interactive computing has resulted in increasingly more complex styles of interaction between user and computer. To facilitate the creation of highly interactive systems, the concept of the User Interface Management System (UIMS) has been developed. Following the definition of the term 'UIMS' and a consideration of the putative advantages of the UIMS approach, a number of User Interface Management Systems are examined. This examination focuses in turn on the run-time execution system, the specification notation and the design environment, with a view to establishing the features which an "ideal" UIMS should possess. On the basis of this examination, a proposal for the design of a new UIMS is presented, and progress reported towards the implementation of a prototype based on this design

We Fish: An Interactive Information Design Mobile app for Local Fishing

Fishing is a popular hobby in today’s society. People enjoy fishing to relieve stress, create social bonds, and find it fulfilling and challenging. In order to fish effectively, a fisherman needs to know the real-time weather, location information, and have basic fishing knowledge. There are many ways we can help fishermen by providing this information in an easily accessible manner. For fishing beginners and fishing amateurs, the best way to help them catch fish is to create a tool that solves their needs. Mobile applications have quickly become a useful tool and are widely used today for its diversity and portability. It can aid promotion and offer great support, increase customer engagement, and provide more value to customers. There are mobile apps for almost every hobby and an app made specifically for its target users will always strive to provide important and relevant information. WeFish, a mobile app designed specifically for fishermen, will provide an excellent opportunity to help fishermen receive real-time notices, learn basic local information and extend their social network. The mission of this project is using UI and UX design to improve fishermen’s satisfaction. The final format of this project is an interactive information web prototype. Through analysis, this thesis project presents a prototype concept for an interactive information app that can engage suitable users, allow for feedback, postings, and reviews, and provide supportive information for the fishing enthusiast

Frameworks for enhancing temporal interface behaviour through software architectural design

The work reported in this thesis is concerned with understanding aspects of temporal behaviour. A large part of the thesis is based on analytical studies of temporal properties and interface and architectural concerns. The main areas covered include: i. analysing long-term human processes and the impact of interruptions and delays ii. investigating how infrastructures can be designed to support synchronous fast pace activity iii.design of the Getting-to-Know (GtK) experimental notification server The work is motivated by the failure of many collaborative systems to effectively manage the temporal behaviour at the interface level, as they often assume that the interaction is taking place over fast, reliable local area networks. However, the Web has challenged this assumption and users are faced with frequent network-related delays. The nature of cooperative work increases the importance of timing issues. Collaborative users require both rapid feedback of their own actions and timely feedthrough of other actions. Although it may appear that software architectures are about the internals of system design and not a necessary concern for the user interface, internal details do show up at the surface in non-functional aspects, such as timing. The focus of this work is on understanding the behavioural aspects and how they are influenced by the infrastructure. The thesis has contributed to several areas of research: (a)the study of long-term work processes generated a trigger analysis technique for task decomposition in HCI (b)the analysis of architectures was later applied to investigate architectural options for mobile interfaces (c)the framework for notification servers commenced a design vocabulary in CSCW for the implementation of notification services, with the aim of improving design (d)the impedance matching framework facilitate both goal-directed feedthrough and awareness In particular, (c) and (d) have been exercised in the development of the GtK separable notification server

A User Interface Management System Generator

Much recent research has been focused on user interfaces. A major advance in interface design is the User Interface Management System (UIMS), which mediates between the application and the user. Our research has resulted in a conceptual framework for interaction which permits the design and implementation of a UIMS generator system. This system, called Graphical User Interface Development Environment or GUIDE, allows an interface designer to specify interactively the user interface for an application. The major issues addressed by this methodology are making interfaces implementable, modifiable and flexible, allowing for user variability, making interfaces consistent and allowing for application diversity within a user community. The underlying goal of GUIDE is that interface designers should be able to specify interfaces as broadly as is possible with a manually-coded system. The specific goals of GUIDE are: The designer need not write any interface code. Action routines are provided by the designer or application implementator which implement the actions or operations of the application system. Action routines may have parameters. The designer is able to specify multiple control paths based on the state of the system and a profile of the user. Inclusion of help and prompt messages is as easy as possible. GUIDE\u27s own interface may be generated with GUIDE. GUIDE goes beyond previous efforts in UIMS design in the full parameter specification provided in the interface for application actions, in the ability to reference application global items in the interface, and in the pervasiveness of conditions throughout the system. A parser is built into GUIDE to parse conditions and provide type-checking. The GUIDE framework describes interfaces in terms of three components: what the user sees of the application world (user-defined pictures and user-defined picture classes) what the user can do (tasks and tools) what happens when the user does something (actions and decisions) These three are combined to form contexts which describe the state of the interface at any time
