THREE DIMENSIONAL MODELING AND ANIMATION OF FACIAL EXPRESSIONS
Facial expression and animation are important aspects of the 3D environment featuring human characters. These animations are frequently used in many kinds of applications and there have been many efforts to increase the realism. Three aspects are still stimulating active research: the detailed subtle facial expressions, the process of rigging a face, and the transfer of an expression from one person to another. This dissertation focuses on the above three aspects.
A system for freely designing and creating detailed, dynamic, and animated facial expressions is developed. The presented pattern functions produce detailed and animated facial expressions. The system produces realistic results with fast performance, and allows users to directly manipulate it and see immediate results.
Two unique methods for generating real-time, vivid, and animated tears have been developed and implemented. One method is for generating a teardrop that continually changes its shape as the tear drips down the face. The other is for generating a shedding tear, which is a kind of tear that seamlessly connects with the skin as it flows along the surface of the face, but remains an individual object. The methods both broaden CG and increase the realism of facial expressions.
A new method to automatically set the bones on facial/head models to speed up the rigging process of a human face is also developed. To accomplish this, vertices that describe the face/head as well as relationships between each part of the face/head are grouped. The average distance between pairs of vertices is used to place the head bones. To set the bones in the face with multi-density, the mean value of the vertices in a group is measured. The time saved with this method is significant.
A novel method to produce realistic expressions and animations by transferring an existing expression to a new facial model is developed. The approach is to transform the source model into the target model, which then has the same topology as the source model. The displacement vectors are calculated. Each vertex in the source model is mapped to the target model. The spatial relationships of each mapped vertex are constrained

Appearance management, dress, and personality
The purpose of this study was to investigate the relationships among appearance management, dress, and personality. Eight hypotheses were developed that proposed relationships among five personality factors, three appearance management variables, and style of dress. Respondents were 277 undergraduate student subjects enrolled at Oregon State University. Subjects completed two questionnaires: 1) the NEO PI-R, an instrument designed to measure five personality factors and their facets; and 2) the Appearance Management and Dress Questionnaire, developed to measure the three appearance management variables of interest in this study and style of dress. Data were analyzed using multiple linear regression and canonical correlation analysis. The results revealed significant relationships among personality factors and/or facets and appearance management and/or dress variables. As hypothesized, lower openness to experience was positively associated with emphasis placed on appearance, higher extraversion was positively associated with receptiveness to a variety of appearances for the self, and personality factors were associated with style of dress. Exploratory regression analyses revealed that specific facets of neuroticism, openness to experience, agreeableness, and conscientiousness were associated with emphasis placed on appearance; and that specific facets of extraversion and openness to experience were associated with receptiveness to a variety of appearances for the self. Exploratory canonical correlation analysis revealed relationships between personality facets and style of dress. Based on the results of the present study, a relationship exists between personality and appearance management and between personality and style of dress. The findings of this investigation have theoretical implications regarding the social/psychological aspects of appearance and dress, personality research, and the marketing and retailing of appearance management products
Personal grooming (beyond hygiene): a grounded theory study.
Background: We are very individualistic in how we present ourselves to the world. Whilst we are healthy and self-caring we have control over the way we undertake self-groom. Once we need care the situation may change. In the setting of health and social care the emphasis has been on hygiene; aspects of personal grooming [PG] may be overlooked. Few studies exist in the health and social care literature that explore this crucial daily activity of living. Aim: This study aims to address the imbalance on what is known of PG. It seeks to thoroughly explore the concept of PG, identifying the normative activities involved, and the age-related behaviours that occur across the lifespan. Methods: Utilising a grounded theory [GT] methodology, an eclectic data collection approach was taken. Consequently a pilot group, four focus groups (child-focused; males 18-45; females 18-45; over-46), and a visual methodology formed the first phase of the study. The second phase consisted of a formal concept analysis, drawing on literature and data from the focus groups. The final phase of the study involved one-to-one semi-structured interviews with retired persons. A total of 26 participants took part in the study and both genders were represented. Analysis was undertaken using the range of coding consistent with a GT approach and the notion of constant comparison. Findings: New knowledge on PG emerged; an academic definition of PG; PG was found to have âfour elementsâ: hygiene, appearance management behaviours, body modification and enhancement. There was a âspectrumâ of grooming recognised, which ranged from the wild, un-groomed state to that of being over-groomed. The term âallo-groomingâ, which means grooming of another, was used to explore the part families play in social learning about PG. A timeline of PG behaviours was created to illustrate how PG changes over the lifespan. Additionally, information on grooming activities, other than those of hygiene, was recorded. Implications: PG is complex and the âone-size-fits-allâ approach of concentrating on hygiene may not meet the needs of service users. Some body areas, for example, are not included in the published documents that help to guide care services. There appears to a gap in educational programmes of health and social care workers, in respect to PG. Recommendations for practice, policy, education and further research are proposed
Presence 2005: the eighth annual international workshop on presence, 21-23 September, 2005 University College London (Conference proceedings)
OVERVIEW (taken from the CALL FOR PAPERS)
Academics and practitioners with an interest in the concept of (tele)presence are invited to submit their work for presentation at PRESENCE 2005 at University College London in London, England, September 21-23, 2005.
The eighth in a series of highly successful international workshops, PRESENCE 2005 will provide an open discussion forum to share ideas regarding concepts and theories, measurement techniques, technology, and applications related to presence, the psychological state or subjective perception in which a person fails to accurately and completely acknowledge the role of technology in an experience, including the sense of 'being there' experienced by users of advanced media such as virtual reality.
The concept of presence in virtual environments has been around for at least 15 years, and the earlier idea of telepresence at least since Minsky's seminal paper in 1980. Recently there has been a burst of funded research activity in this area for the first time with the European FET Presence Research initiative. What do we really know about presence and its determinants? How can presence be successfully delivered with today's technology? This conference invites papers that are based on empirical results from studies of presence and related issues and/or which contribute to the technology for the delivery of presence. Papers that make substantial advances in theoretical understanding of presence are also welcome. The interest is not solely in virtual environments but in mixed reality environments. Submissions will be reviewed more rigorously than in previous conferences. High quality papers are therefore sought which make substantial contributions to the field.
Approximately 20 papers will be selected for two successive special issues for the journal Presence: Teleoperators and Virtual Environments.
PRESENCE 2005 takes place in London and is hosted by University College London. The conference is organized by ISPR, the International Society for Presence Research and is supported by the European Commission's FET Presence Research Initiative through the Presencia and IST OMNIPRES projects and by University College London
