End-user GUI customization BIBAKFull-Text 1-8
  Christof Lutteroth; Gerald Weber
Constraint-based description of GUI layout is a powerful technique, but having to define constraints manually is not user friendly. We propose a GUI editor for the Auckland Layout Model (ALM) that can handle constraint-based layout in a WYSIWIG manner, making it much easier to create or modify complex layouts. Furthermore, the GUI editor is built into the layout manager that is used during the runtime of a GUI application, making it accessible to the end-user. Users can switch from the operational mode of a GUI into the editing mode, and immediately adjust the GUI to their needs. GUI specifications can be managed in a platform-independent XML-based description language, leading to a document-oriented paradigm for GUIs. The implementation of GUIs currently changes from hard-coded GUIs to document-based approaches such as XAML and XUL. Sadly, this shift is currently performed as a mere reengineering of the development process and driving forces are chiefly productivity and maintainability. Our approach, in contrast, aims at enhancing user options and also platform-independence.

Interactive visualisation techniques for dynamic speech transcription, correction and training BIBAKFull-Text 9-16
  Saturnino Luz; Masood Masoodian; Bill Rogers
As performance gains in automatic speech recognition systems plateau, improvements to existing applications of speech recognition technology seem more likely to come from better user interface design than from further progress in core recognition components. Among all applications of speech recognition, the usability of systems for transcription of spontaneous speech is particularly sensitive to high word error rates. This paper presents a series of approaches to improving the usability of such applications. We propose new mechanisms for error correction, use of contextual information, and use of 3D visualisation techniques to improve user interaction with a recogniser and maximise the impact of user feedback. These proposals are illustrated through several prototypes which target tasks such as: off-line transcript editing, dynamic transcript editing, and real-time visualisation of recognition paths. An evaluation of our dynamic transcript editing system demonstrates the gains that can be made by adding the corrected words to the recogniser's dictionary and then propagating the user's corrections.

Towards the design of a kids' music organizer BIBAKFull-Text 17-22
  Manuela Hutter; Sally Jo Cunningham
In this paper, we investigate how young children aged 2 to 5 interact with music and their family's music collections. By going into their homes, interviewing them and their parents and observing the children performing a range of music-related tasks, we explore the way that pre-school children select, interact with, and organize music. Additionally, drawing tasks were included in the visits to engage the children and allow them to demonstrate their thoughts in a concrete manner. Insights into the children's' music behaviours suggest design features for a music organizer / player for very young children.

Issues of extending the user interface of integrated development environments BIBAKFull-Text 23-30
  Samuel Hsiao-Heng Chang; Xiaofan Chen; Richard Anthony Priest; Beryl Plimmer
The current level of extensibility of integrated development environments (IDEs) does not provide sufficient access to make modifications to their user interface components. This limits innovation in IDEs. This paper reviews the problems we have encountered and presents alternative ways to help developers achieve their goals of extending user interface components. Developers interested in extending existing applications will appreciate the information on likely problems and solutions with extensible architectures. Furthermore general suggestions for software architecture extensions to maximize extensibility are included.

Interface evaluation for invisibility and ubiquity: an example from e-learning BIBAKFull-Text 31-38
  Elizabeth A. Kemp; Ashleigh-Jane Thompson; Russell S. Johnson
This paper reports on the development of a framework for the heuristic evaluation of the interface to a learning appliance, that is a teaching system where students can study the course content without thinking about the technology. It has been argued that in systems of this kind the emphasis should be on invisibility, usability, universality and usefulness. A set of heuristics was generated based on those for evaluating web and ubiquitous systems but tailored to the requirements of a learning appliance. These heuristics were used to evaluate IMMEDIATE (Integrating MulitMEdia in a DIstAnce learning and TEaching environment), a teaching system intended to address the digital divide in education by providing a specialised, easy-to-use, e-learning environment for the PC. The results indicated that whilst IMMEDIATE supports the appropriate functionality, some improvements can be made to enhance the learning experience.

Encouraging better hand drying hygiene BIBAKFull-Text 39-45
  Sally Jo Cunningham; Andrew Will
Electric hand driers have the potential to improve sanitation when using public toilets; if used properly, electric driers can dry hands more thoroughly than towels, and users do not come into physical contact with potentially contaminated objects. But electric driers are frequently used for just a few seconds -- and so the potential advantage is lost. This paper describes the prototyping and evaluation of a system intended to encourage longer hand drying times in public toilets. The challenges are: to develop hygienic interfaces for use in toilet areas; to design simple to use software that is engaging enough to be used several times a day; and to conduct usability and system acceptance tests in an environment in which users are highly sensitive about privacy issues.

Directional interfaces for wearable augmented reality BIBAKFull-Text 47-54
  Volkert Buchmann; Mark Billinghurst; Andy Cockburn
Wearable Augmented Reality can be used to overlay information onto the real world. Directional interfaces in wearable Augmented Reality aid users to orient themselves so that previously invisible targets are now inside their field of view. This is relevant when the user tries to find the next waypoint during a navigational task. We surveyed directional interfaces that have been used in Augmented Reality previously and compared their efficiency. We have found that a circular compass is the most efficient way to provide orientation cues.
