Reading with Mobile Phone & Large Display (2008)
Gostner, Roswitha, Gellersen, Hans, Kray, Christian, Sas, Corina
In this paper we compare performance and usability between three different device combinations: a) mobile phone b) touch screen c) mobile phone & screen. We show that mobile phone & screen has a...
Spatial Data Fusion with Visual Feedback (2008)
Nikita Schmidt, Corina Sas, Sam Barnett-cormack, La Wa
This paper outlines our ongoing work towards developing a system for extracting patterns embedded in heterogeneous data streams that contain people’s recorded movements in both physical and virtual...
Software Usability: A Comparison Between Two Tree- Structured Data Transformation Languages (2008)
This paper presents the results of a software usability study, involving both subjective and objective evaluation. It compares a popular XML data transformation language (XSLT) and a general purpose...
Geometric Algorithms, Languages, and Systems General Terms (2008)
This paper proposes a novel method of modelling trajectories followed by users, while they navigate within a virtual environment. Bézier curves provide a good approximation of trajectories, and the...
Why bad ideas are a good idea (2008)
Alan Dix, Tom Ormerod, Michael Twidale, Corina Sas, Paula Alex, ...
What would happen if we wrote an Abstract that was the exact opposite of what the paper described? This is a bad idea, but it makes us think more carefully than usual about properties of Abstracts....

Lessons learned from building and deploying three experimental public display systems have general applicability to many types of public ubicomp deployments.
A Typology of Course of Motion in Simulated Environments Based on Bezier Curve Analysis. (2007)
This paper proposes a novel method of analysing trajectories followed by people while they perform navigational tasks. The results indicate that modelling trajectories with Bézier curves provides a...
Public ubiquitous computing systems: Lessons from the e-campus display deployments. (2006)
Storz, Oliver, Friday, Adrian, Davies, Nigel, Finney, Joe, Sas, Corina, Sheridan, Jennifer
In this paper we reflect on our experiences of deploying ubiquitous computing systems in public spaces and present a series of lessons that we feel will be of benefit to researchers planning similar...
Cheverst, Keith;, Byun, Hee Eon;, Fitton, Dan;, Sas, Corina;, Kray, Chris;, Villar, Nicolas
It is important that systems that exhibit proactive behaviour do so in a way that does not surprise or frustrate the user. Consequently, it is desirable for such systems to be both personalised and...
Sas, Corina, O'Hare, Gregory, Reilly, Ronan
This paper describes the analysis and clustering of motion trajectories obtained while users navigate within a virtual environment (VE). It presents a neural network simulation that produces a set of...
Presence Equation: An Investigation Into Cognitive Factor Underlying Presence. (2003)
The relationship between presence and cognitive factors such as absorption, creative imagination, empathy, and will ingness to experience presence was investigated. Presence was defined,...
Electronic Navigation - Some Design Issues (2003)
C. Sas, M. J. O'Grady, G. O'Hare, Corina Sas
Navigation support will form a critical component of future mobile computing systems. However, the ability of people to navigate in unfamiliar environments can vary substantially. In this paper, it...
G.: A Connectionist Model of Spatial Knowledge Acquisition in a Virtual Environment (2003)
Abstract. This paper proposes the use of neural networks as a tool for studying navigation within virtual worlds. Results indicate that the network learned to predict the next step for a given...
Presence Equation: An Investigation into Cognitive Factors Underlying Presence (2003)
Psychological approaches to the study of presence are limited, and those with experimental support even more limited. This work is an attempt to highlight the human factors involved which may lead to...
