Using remotely executing software via a mobile device BIBAFull-TextPDF 3-8
  Vipul Delwadia; Stuart Marshall; Ian Welch
There are scenarios in mobile computing that may benefit from separating presentation from computation. Traditionally this separation can be achieved via tools such as VNC. However such factors as network latency and additional communication overhead can slow down the presentation of a remotely executing mobile application below acceptable performance levels, especially for domains like gaming where responses may need to appear to be instantaneous. We present RemoteMe, an architecture and Java-based prototype for mobile-client / server communication that only requires a very thin mobile client. We hypothesise that RemoteMe will support faster response times to user input than existing software solutions such as VNC. This paper presents a preliminary analysis of our first prototype, and experimentally compares it to an open-source mobile-based VNC system.
Augmenting image plane AR 3D interactions for wearable computers BIBAFull-TextPDF 9-15
  Thuong N. Hoang; Shane R. Porter; Bruce H. Thomas
This paper presents a set of large object manipulation techniques implemented in a wearable augmented reality computer system that are optimised for the outdoor setting. These techniques supplement the current image plane approach, to provide a comprehensive solution to 3D object manipulation in an augmented reality outdoor environment. The three extended manipulation techniques, Revolve, Xscale, and Ground plane translation, are focused on using what we determined to be the best coordinate system for object rotation, scaling and translation. This paper goes on to present the generalised plane technique for the constrained translation of graphical objects on arbitrary planes to enable more complex translation operations. The paper presents the techniques from both the user interface and software development perspectives.
Using Machinima to promote computer science study BIBAFull-TextPDF 17-25
  Christian Jones; Callum Munro
The project develops a Machinima animation promotional film for the Department of Computer Science at Heriot-Watt University, and evaluates whether the promotional material is more engaging and entertaining than traditional materials; more informative about the provider (its values and facilities); promotes Computer Science as relevant to student lives; uses media immediately recognisable to the student; and is innovative and differentiates the provider from others in the marketplace. Real interviews with current students relating their likes and dislikes of the University were coupled with computer game animation to create an entertaining and informative multimedia advertisement. The multi-stage evaluation with potential applicants has shown that these students respond positively to the content and presentation of the innovative multimedia film, and are encouraged to choose Computer Science and Heriot-Watt University for Tertiary education.
Multi-platform document-oriented GUIs BIBAFull-TextPDF 27-34
  James Kim; Christof Lutteroth
In recent years, increasing complexity of graphical user interfaces (GUIs) of applications has led to problems in GUI management, since there is no single layout to fulfill every user's needs. GUI editors have been developed to enhance end-user options but they commonly fail to preserve personalized GUIs. This paper presents an extension to the GUI editor built into the Auckland Layout Model (ALM) that can permanently store user-defined GUI layouts and reproduce them on different platforms. A novel technique called the document-oriented approach has been exploited to empower end-user customization, which allows GUI layouts to be dynamically edited, saved using a standardized XML-based GUI description language, and loaded in a platform-independent manner.
A citation analysis of the AUIC 2006-2008 proceedings, with reference to the CORE conference and journal rankings BIBAFull-Text 35-44
  Raymond Lister; Ilona Box
This paper compares the CORE rankings of computing conferences and journals to the frequency of citation of those journals and conferences in the Australasian User Interface Conference (AUIC) 2006, 2007 and 2008 proceedings. The assumption underlying this study is that there should be a positive relationship between citation rates and the CORE rankings. Our analysis shows that CORE conference and journal rankings broadly reflect the AUIC citations, but we note some anomalies. While these anomalies might be minor in the larger scheme of things, any anomalies need to be addressed, as the careers of individual academics may depend upon it. The concept of conference and journal rankings is probably here to stay, and this paper ends with some suggestions on how the rankings process should now evolve, so that it becomes more transparent.
Assessing usability for input operation using frequency components of eye-movements BIBAFull-TextPDF 45-52
  Minoru Nakayama; Makoto Katsukura
Dynamic usability-testing is required for the improvement of various Human-Computer interactive systems. This paper examines the indices of assessing usability using the frequency spectrum of eye-movements up to four Hz. An input operational task experiment was conducted using a mouse (Mouse), a keyboard (KeyBD) and a keypad (KeyPAD), and the conventional subjective system usability measurements (SU-scores) and error rates were measured. Most power spectrum densities (PSD) for eye-movements in the first second of the experiment followed the same order of the SU-scores or error rates. Cross spectrum densities (CSD) between horizontal and vertical eye-movements and coherence as standardized CSD also significantly correlate with the results of the SU-scores and error rates. To determine the frequency range of CSD and coherence for usability assessment, frequency components used as factors were extracted using factor analysis. According to the correlation coefficients between these and the performance of factor scores for predicting the conventional metrics, factor scores of CSD can be better indices for assessing usability than can indices of coherence.
Sketching ER diagrams BIBAFull-TextPDF 53-60
  Paul Schmieder; Beryl Plimmer; Gillian Dobbie
Hand-drawn diagrams are frequently used as the first visualization of a model. Converting these preliminary diagrams into a specific formal format is time consuming. Computer based sketch-tools can offer support during the informal sketching stage and automatic conversion to formal representations. Entity Relationship diagrams are particularly difficult to convert because of their characteristics such as cardinality notations. We extend the general diagram sketching tool InkKit with domain semantics to successfully recognize and automatically convert Entity Relationship diagrams. This approach takes advantage of sketching as the preferred initial design realization while minimizing the effort required to translate the initial design to a functional prototype.
Comparison of techniques for mixed-space collaborative navigation BIBAFull-TextPDF 61-70
  Aaron Stafford; Bruce H. Thomas; Wayne Piekarski
This paper describes the results of two studies conducted to determine the role of visual cues for a collaborative navigation task in a mixed-space environment. Both studies required a user with an exocentric view of a virtual room to navigate a fully immersed user with an egocentric view to an exit. The first study compares natural hand-based gestures, a mouse-based interface and an audio-only technique to determine their relative efficiency on task completion times. The follow-up study compares natural hand-based gestures against a mouse-based interface in a scenario in which participants are unable to communicate verbally.
   The results show that visual cue-based collaborative navigation techniques are significantly more efficient than an audio-only technique. The results also show that natural hand gestures are more expressive and lead to quicker completion times in situations where verbal communication is not possible.
