5. Computer graphic control over human face and head appearance : genetic optimisation of perceptual characteristics

Author

Abstract

The aims of this thesis are two-fold. The first is to develop computer graphics that allow quantitative manipulation of complex visual stimuli. The second is to show that such techniques have utility in the domain of perceptual psychology. There are three main sections to this thesis. The first section creates methods for performing transformations of facial appearance along particular perceptual dimensions. This work begins with 2-D image manipulations and then extends the general principles to 3-D. Effectiveness of the techniques is illustrated with plates showing transformation in age, gender and identity. The second section uses Genetic Algorithms to control the appearance of 3-D computer graphics objects and investigates methods of evolving objects that embody various consumer concepts. Computer graphic models of shampoo bottles are successfully evolved to satisfy a selection of aesthetic and perceptual characteristics. The final section returns to facial stimuli and extends the Genetic Algorithm approach to investigate aesthetic preference for 3-D facial surfaces. The study shows that individual human subjects can evolve facial surfaces based upon their own attractiveness preferences. The faces evolved are non-average and there is consistency between subjects about preferred characteristics. The three parts of this thesis have different theoretical backgrounds and literature relevant to each topic is therefore reviewed at the start of each section.

21. Co-viewing TV with Twitter: more interesting than the shows?

Author

Doughty, Mark, Rowland, Duncan, and Lawson, Shaun

Subjects

Abstract

Social media services, and Twitter in particular, are changing the way in which many people consume traditional broadcast media. Real-time backchannel conversations are now common-place as audiences simultaneously watch TV whilst using Twitter to broadcast their own thoughts, sentiments, opinions and emotions related to what they are watching. This individual behavior, when aggregated, results in a new social experience comprising of mass, real-time, coconsumption of TV services that has, thus far, been neither recognized nor investigated by the HCI community nor the broadcast industry. This paper describes a work-in-progress which aims to understand user behaviour in this burgeoning area and provides some preliminary analysis of viewers’ Twitter activity surrounding the popular UK TV show, The X Factor.

22. Recommending rides: psychometric profiling in the theme park

Author

Rennick-Egglestone, Stefan, Whitbrook, Amanda, Greensmith, Julie, Walker, Brendan, Benford, Steve, Marshall, Joe, Kirk, David, Irune, Ainoje, and Rowland, Duncan

Abstract

This paper presents a study intended to inform the design of a recommender system for theme park rides. It examines the efficacy of psychometric testing for profiling theme park visitors, with the aim of establishing a set of measures to be included in a visitor profile intended for use in a collaborative recommender system. Results presented in this paper highlight the predictive value of a number of psychometric measures, including two drawn from the ?Big Five? personality inventory, and one drawn from the ?Sensation Seeking Scale?. The paper discusses general research challenges associated with the integration of psychometric testing into recommender systems, and describes planned future work on a theme park recommender system.
