  • The behavioural impact of a visually represented virtual assistant in a self-service checkout context 

    Payne, Jeunese A.; Johnson, Graham I.; Szymkowiak, Andrea (British Computer Society, 2011)
    Our research investigated whether the presence of an interface agent -- or virtual assistant (VA) -- in a self-service checkout context has behavioural effects on the transaction process during particular tasks. While many ...
  • Beyond embodiment and social presence: preferences for virtual assistant gender and clothing style 

    Payne, Jeunese A.; Szymkowiak, Andrea; Johnson, Graham; Robertson, Paul; Henderson, Rosemary (2012)
    While introducing a human-like embodied character can enhance social presence in computing technology, it can often be poorly received because user preferences for particular appearance-based attributes are not taken into ...
  • Changing the view: towards the theory of visualisation comprehension 

    Shovman, Mark M.; Szymkowiak, Andrea; Bown, James L.; Scott-Brown, Kenneth C. (Institute of Electrical and Electronics Engineers, 2009-07)
    The core problem of the evaluation of information visualisation is that the end product of visualisation - the comprehension of the information from the data - is difficult to measure objectively. This paper outlines a ...
  • The effects of cooperative and competitive games on classroom interaction frequencies 

    Creighton, Susan; Szymkowiak, Andrea (Elsevier, 2014-08-22)
    This research looks at the effects of playing cooperative and competitive computer games on pupils’ classroom interaction frequency, as an index of their cooperation and engagement in class. It was predicted that students ...

    To respond to an ageing population, eHealth strategies offer significant opportunities in achieving a balanced and sustainable healthcare infrastructure. Advances in technology both at the sensor and device levels and in ...
  • Gender and hazard perception skills in relation to road traffic police officers 

    Scrimgeour, Anne; Szymkowiak, Andrea; Hardie, Scott; Scott-Brown, Kenneth C. (SAGE, 2011-12)
    Gender differences have been observed in driving styles and in the types of reported collisions that males and females are involved in. This study was conducted to examine gender differences in a hazard perception task ...
  • Gendering the machine: preferred virtual assistant gender and realism in self-service 

    Payne, Jeunese; Szymkowiak, Andrea; Robertson, Paul; Johnson, Graham (Springer, 2013)
    A virtual agent is a human-like character that is designed to assist users in interactions with technology and virtual worlds. Research into the preferred visual characteristics of a virtual agent has focused on education-based ...
  • Information visualization and the arts-science-social science interface 

    Bown, James L.; Fee, Kenneth; Sampson, Adam T.; Shovman, Mark; Falconer, Ruth E.; Goltsov, Alexey; Issacs, John P.; Robertson, Paul; Scott-Brown, Kenneth C.; Szymkowiak, Andrea (ACM, 2010)
    In a world of ever-increasing and newly discovered complexities, and rapidly expanding data sets describing man-made and natural phenomena, information visualization offers a means of structuring and enabling interpretation ...
  • Investigating the future of self-service technology 

    Robertson, Paul; Szymkowiak, Andrea; Johnson, Graham (BCS, 2010)
    In this paper we describe an ongoing research project between NCR Dundee and Abertay University to investigate the future of self-service technology for entertainment. The aim was to assess how future technologies may be ...
  • An investigation into gender role conformity in an online social networking environment 

    Fawzi, Alexander; Szymkowiak, Andrea (Springer, 2014)
    Social networking sites (SNS) offer a relatively novel arena in which to display and investigate social behavior. The study investigated consistency between social behaviors typical of traditional (offline) social interactions ...
  • Is visual search a high-level phenomenon? Evidence from structure perception in 3-D scatterplots 

    Shovman, Mark; Szymkowiak, Andrea; Bown, James L.; Scott-Brown, Kenneth C. (Pion, 2010)
    Increasing use of 3-D scatterplots for trend detection in visual analytics, raises the theoretical question: what constitutes an object in such a task? Previously (Shovman et al, 2008 Perception 37 79 ^ 80) we have shown ...
  • Joint attention for pointing but not grasping postures 

    Fischer, Martin H.; Szymkowiak, Andrea (Elsevier Masson, 2004)
    “Joint attention” refers to changes in one`s own action potentials after observing somebody else’s actions. For example, perceived gaze leads to corresponding attention shifts (Hood et al., 1998; Schuller and Rossion, ...
  • Keystroke dynamics in the pre-touchscreen era 

    Ahmad, Nasir; Szymkowiak, Andrea; Campbell, Paul A. (Frontiers, 2013-12-19)
