Work at hand: an exploration of gesture in the context of work and everyday life to inform the design of gestural input devices BIBAFull-Text 1-10
  Margot Brereton; Nicola Bidwell; Jared Donovan; Brett Campbell; Jacob Buur
This research explores gestures used in the context of activities in the workplace and in everyday life in order to understand requirements and devise concepts for the design of gestural information appliances. A collaborative method of video interaction analysis devised to suit design explorations, the Video Card Game, was used to capture and analyse how gesture is used in the context of six different domains: the dentist's office; PDA and mobile phone use; the experimental biologist's laboratory; a city ferry service; a video cassette player repair shop; and a factory flowmeter assembly station. Findings are presented in the form of gestural themes, derived from the tradition of qualitative analysis but bearing some similarity to Alexandrian patterns. Implications for the design of gestural devices are discussed.
An empirical study of textual and graphical travel itinerary visualization using mobile phones BIBAFull-Text 11-18
  Masood Masoodian; Nicholas Lane
Mobile phones can be used to access personal and public information. Although most of these types of information are in textual form, an increasing number of service providers are also offering access to graphical information, particularly to WAP™ enabled mobile phones. This paper describes an empirical study of user access to personal travel itinerary information in both textual and graphical form. The aim of this study was to compare the effectiveness of graphical and textual visualizations in providing users with easy access to different kinds of information on their travel itinerary. The study indicates that although the graphical visualization was generally as effective as textual visualization, the users preferred textual visualization to a graphical one, possibly because they were more familiar with textual itineraries.
Non-invasive adaptation of black-box user interfaces BIBAFull-Text 19-24
  D. Rose; S. Stegmaier; G. Reina; D. Weiskopf; T. Ertl
In this paper a new method for the non-invasive adaptation of user interfaces is presented. The main idea is not to implement the user interface toolkit as an API, but instead as an object file that redefines the functionality of the API of an already existing toolkit in a generic way based on a so-called preloading technique. Compared to common approaches, the presented method allows us to evaluate prototypical user interfaces with a large number of real-world applications with very little effort. If the prototype proves useful, the new user interface is instantly available for all applications based on the redefined toolkit, which significantly simplifies the spreading of new interaction techniques and ideas. We illustrate the procedure by means of adapting the user interface of a 3D graphical application based on a widely used toolkit for use on handheld computers.
Icons R icons BIBAFull-Text 25-32
  Pippin Barr; James Noble; Robert Biddle
Icons are used in almost every graphical user-interface to computer software. Despite this, there is a serious lack of comprehension of what they are and how they work. The application of semiotics to user-interface icons can help to solve this problem by providing a framework for understanding icons in. This paper suggests such a semiotic approach and then applies it to real-world icons to show its effectiveness. Some hypothetical guidelines are derived from the application and a strong analytic technique results.
Get a way back: evaluating retrieval from history lists BIBAFull-Text 33-38
  Michael JasonSmith; Andy Cockburn
Many user interfaces include history lists that help users retrieve temporally ordered information such as previously visited web pages, email messages, and recently used files. Two main types of history lists are widely used. The first type, typified by Netscape Navigator's history list, provides a linear temporally ordered list. The second type, typified by Microsoft Internet Explorer's history list, provides a hierarchical structure based on temporal chucks such as "Today" and "Last Week" at the top level, alphabetically ordered websites at the second level, and alphabetically ordered pages at the lowest level. Despite the wide use of these different types of list, we are unaware of research into their relative merits. This paper describes an experiment that investigates the efficiency of retrieval from four different types of history lists, derived from the two main alternatives described above. The results indicate that simple linear ordering of information is superior to more sophisticated structures.
The design and evaluation of a flick gesture for 'back' and 'forward' in web browsers BIBAFull-Text 39-46
  Michael Moyle; Andy Cockburn
Web navigation relies heavily on the use of the 'back' button to traverse pages. The traditional back button suffers from the distance and targeting issues that govern Fitts' Law. An alternative to the button approach is the use of marking menus -- a gesture based technique shown to improve access times of commonly repeated tasks. This paper describes the implementation and evaluation of a gesture-based mechanism for issuing the back and forward commands in web navigation. Results show that subjects were able to navigate significantly faster when using gestures compared to the normal back button. Furthermore, the subjects were extremely enthusiastic about the technique, with many expressing their wish that "all browsers should support this". Subjective measures also showed significantly higher ratings for the gesture system over the back button. Finally, subjects found the 'flick' gesture easy to learn.
An environment for developing adaptive, multi-device user interfaces BIBAFull-Text 47-56
  John Grundy; Biao Yang
There is a growing demand for the development of multi-device, adaptive user interfaces -- interfaces that will run on and adapt to the characteristics of multiple display devices and networks as well as multiple users and user tasks. We describe a design and implementation environment for the development of such interfaces. This tool allows developers to specify their desired interfaces using an abstract set of screen element and layout constructs. It then generates a Java Server Page implementation using a custom tag library that realises a multi-device, adaptive interface. We compare and contrast our approach to other techniques and describe our experiences using it.
Real-time simulation of deformable objects for assembly simulations BIBAFull-Text 57-64
  Ralf Rabaetje
This paper describes the integration of deformable objects into a VR assembly simulation. The deformable objects are flexible hoses, which are simulated using corotational beams. The simulation is enhanced by specific load cases in order to fully match the needs of the assembly tasks. A virtual reality system is used as an intuitive man-machine interface to the calculation model. Comparisons between the results obtained by this system and classical finite element programs are given to obtain an error estimate for the simulation.
Location based applications for mobile augmented reality BIBAFull-Text 65-73
  Gerhard Reitmayr; Dieter Schmalstieg
In this work we investigate building indoor location based applications for a mobile augmented reality system. We believe that augmented reality is a natural interface to visualize spacial information such as position or direction of locations and objects for location based applications that process and present information based on the user's position in the real world. To enable such applications we construct an indoor tracking system that covers a substantial part of a building. It is based on visual tracking of fiducial markers enhanced with an inertial sensor for fast rotational updates. To scale such a system to a whole building we introduce a space partitioning scheme to reuse fiducial markers throughout the environment. Finally we demonstrate two location based applications built upon this facility, an indoor navigation aid and a library search application.
User interface requirements for authentication of communication BIBAFull-Text 75-80
  Audun Jøsang; Mary Anne Patton
Authentication is a security service that consists of verifying that someone's identity is as claimed. There are a number of challenges to presenting information from the authentication process to the user in a way that is meaningful and ensures security. We show examples where authentication requirements are not met, due to user behaviour and properties of existing user interfaces, and suggest some solutions to these problems.
Use of video shadow for small group interaction awareness on a large interactive display surface BIBAFull-Text 81-90
  Mark Apperley; Laurie McLeod; Masood Masoodian; Lance Paine; Malcolm Phillips; Bill Rogers; Kirsten Thomson
This paper reports work done as part of the Large Interactive Display Surface(LIDS) project at the University of Waikato. One application of the LIDS equipment is distributed meeting support. In this context large display surfaces are used as shared workspaces by people at collaborating sites. A meeting will start with a shared presentation document, typically an agenda document with summary and detail on agenda items as required. During the meeting, annotations will be made on the shared document, and new pages will be added with notes and drawings. To prevent access collisions and generally mediate use of the shared space, mechanisms to provide awareness of actions of people at other sites are required. In our system a web camera is used to capture a low-resolution image of the person/people near the board on each side. Rather than transmit the image directly we compute a shadow/silhouette The shadow is displayed 'behind' other screen content. This provides awareness of position and impending write actions and allows intentional pointing to locations on the screen. It also has the advantages of being transmitted with low bandwidth, being relatively insensitive to low frame rates, and minimizing visual interference with the substantive data being displayed on the screen.
Spreadsheet structure inspection using low level access and visualisation BIBAFull-Text 91-94
  Daniel Ballinger; Robert Biddle; James Noble
Spreadsheets are an extremely common form of end-user programming used for many applications from student marks to accounting for global multinationals. Ways of studying the structure of a spreadsheet itself is normally constrained to the tools provided in the spreadsheet software. We wanted to explore ways to use new visualisations for spreadsheets, and this paper documents our approach.
A lightweight web-based case tool for UML class diagrams BIBAFull-Text 95-98
  Daniel Mackay; James Noble; Robert Biddle
Many existing UML tools are far too heavyweight for quickly producing a few simple models. These heavyweight UML tools usually contain large amounts of functionality, which can lead to usability problems and poor productivity. Lightweight web-based UML tools are designed to support quick and easy production of models. The use of the web has added benefits including portability and group collaboration. This report discusses lightweight groupware UML case tools and presents a lightweight web-based class diagram editor that requires no web browser extensions.
Keg master: a graph-aware visual editor for 3D graphs BIBAFull-Text 99-103
  Hannah Slay; Matthew Phillips; Bruce Thomas; Rudi Vernik
This paper presents Keg Master, a graph-aware visual editor for 3D graphs. Keg Master is novel in that it works with a graph description language as opposed to a scene graph description language. Keg Master supports a range of 3D graph operations. Graphs may be stored to and retrieved from files. A range of objects may be added to a graph, cone, cube, sphere, and edge. Attributes may be specified to the nodes and edges. These properties of edges may interactively changed to allow users to better understand the graphic structure.
