Online avatar based interactions

The gridWorld project attempts to utilize 3D to develop an online multi-user visual chat system. GridWorld address ideas of how conversations in a virtual environment can be facilitated and enhanced by an abstract visual interface design. The visual interface was developed from research and examination of existing ideas, methodologies and application for development of user-embodiment, chat/virtual space, and interface useability towards the visualization of communication

Designing a visual component of communication within 3D avatar virtual worlds

Merged with duplicate record 10026.1/2600 on 08.20.2017 by CS (TIS)Over the last few years 3D avatar virtual worlds (AVW) have emerged on the Internet. These are computer generated, multi-user, graphical spaces within which people meet, form social groups and interact with each other in real time, typically through the exchange of text or audio messages. Each user is represented within the space by a digital image known as an avatar, which is usually humanoid in form, and is predominantly under the control of the person it represents. This thesisd escribesa creativep roject that is concernedw ith aspectso f social communication between users of "Ws. In particular, an avatar is designed that is capable of performing body language, and a set of useful gestures are implemented that support aspects of social interaction and integrate with verbal discourse in a meaningful way. In addition to this, a number of scenic properties are derived that enable better comprehension of the non verbal communication, e. g. spatial arrangement, camera position and lighting effects. The research consists of a number of interrelated design activities which include reviewing the literature on avatar design in order to locate goals and variety of the project, therefore building on the on the work of others; a comparative review of three popular 3D AVWs to explore the design problem; a study that aims to gain an understanding of the social dynamics involved; the adaptation of a diagrammatic technique for the purpose of modelling social interaction; the development of 2D and 3D prototype techniques exploring the application of the social interaction modelling technique; a body of creative work developing ideas for conveying non verbal communication and the appraisal of the effectiveness of this creative work. The research contributes to the field of avatar design in a number of ways. Firstly, it develops our understanding of social dynamics in virtual worlds. Secondly, it postulates modes of non verbal communication for both individuals and social groups that supports multi-participatory social discourse. Additionally, a number of useful research techniques have been devised, such as a linear diagramming technique that can be used to represent the structure of conversation thereby facilitating the exploration and understanding of the dynamics of AVW social discourse. The work is of interest to those working in the field of avatar and multi-user virtual world design. It may also be of interest to anyone thinking of using an avatar virtual world for the application of collaborative leaming, collaborative games and conferencing

Algorithmic architecture in virtual spaces

Thesis (S.M.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2008.Includes bibliographical references (p. 87-92).Much of the recent interest in virtual worlds has focused on using the immersive properties of virtual worlds to recreate an experience like that of interacting face to face with other participants. This thesis instead focuses on how we can use the distinctive properties of virtual spaces to create experiences native to virtual worlds. I present two projects that have different perspectives on this concept. The first project--Information Spaces--demonstrates how visualization of behavior in a 3d meeting space can augment the meeting process and provide participants new behavioral ways to communicate. The second project--*Space--is an abstract 2d virtual platform for prototyping and experimenting with virtual world experiences that provides a structure for changing properties of the virtual space to influence people's behavior in that space.Drew Harry.S.M

A study of verbal and nonverbal communication in Second Life - the ARCHI21 experience

To appear in 2013. This is not the final version.Three-dimensional synthetic worlds introduce possibilities for nonverbal communication in computer-mediated language learning. This paper presents an original methodological framework for the study of multimodal communication in such worlds. It offers a classification of verbal and nonverbal communication acts in the synthetic world Second Life and outlines relationships between the different types of acts that are built into the environment. The paper highlights some of the differences between the synthetic world's communication modes and those of face-to-face communication and exemplifies the interest of these for communication within a pedagogical context. We report on the application of the methodological framework to a course in Second Life which formed part of the European project ARCHI21. This course, for Architecture students, adopted a Content and Learning Integrated Learning approach (CLIL). The languages studied were French and English. A collaborative building activity in the students L2 is considered, using a method designed to organise the data collected in screen recordings and to code and transcribe the multimodal acts. We explore whether nonverbal communication acts are autonomous in Second Life or whether interaction between synchronous verbal and nonverbal communication exists. Our study describes how the distribution of the verbal and nonverbal modes varied depending on the pre-defined role the student undertook during the activity. We also describe the use of nonverbal communication to overcome verbal miscommunication where direction and orientation were concerned. In addition, we illustrate how nonverbal acts were used to secure the context for deictic references to objects made in the verbal mode. Finally, we discuss the importance of nonverbal and verbal communication modes in the proxemic organisation of students and the impact of proxemic organisation on the quantity of students' verbal production and the topics discussed in this mode. This paper seeks to contribute to some of the methodological reflections needed to better understand the affordances of synthetic worlds, including the verbal and nonverbal communication opportunities Second Life offers, how students use these and their impact on the interaction concerning the task given to students

Technology Mediated Dispute Resolution (TMDR): A New Paradigm for ADR

Technology is changing the way that children are communicating (particularly elementary and pre-school aged children), and these changes have significant implications for alternative dispute resolution processes and practices. Although ADR practitioners and theorists are not ignoring technology, we have focused almost exclusively on the question of how we can use technology to enhance our existing practices. We are not paying sufficient attention to the fact that young children are communicating differently than we communicate. Insufficient energy is being dedicated to the question of how those differences in communication inevitably influence the way that those children resolve disputes. The article analyzes social science research that describes and documents how technology is changing the ways in which children are communicating. The successes of software and hardware developers are coming so quickly that it is difficult for those of us outside the technology fields to stay informed. Dispute resolvers are not asking how new technologies, technologies of which we may not even be aware (or at least not fully understand), are changing the way that our children are communicating. We also are not asking how those changes affect alternative dispute resolution. The article suggests ways in which ADR will change as a result of the ways children are communicating. It also discusses the future of current theories and approaches to ADR, such as mindfulness meditation (frequently discussed by Professor Leonard Riskin, among others)

Avatar Taxonomy: A New Technological Tool to Enhance the Consumer-Brand Relationships

PurposeAvatars, which are used as a technology and marketing tactic, can embody consumer-facing employees and mimic their real-life roles on companies' websites, thereby playing a key role in enhancing the relationships between consumers and brands in the online environment. Academics and practitioners have increasingly acknowledged the significance of the consumer-brand relationship in both traditional and online contexts. However, the impersonal nature of the online environment is considered to be a hindrance to the development of these relationships. Despite the importance of this technology, little attention has been paid to the investigation of the avatar concept from a marketing perspective. This paper explores the nature of the avatar concept, including its main characteristics, dimensions, and conditions as well as the attitudinal and behavioural consequences of avatar users.Design/methodology/approachAdopting the qualitative design, a taxonomy was developed from interviews. In total, 42 interviews were conducted with current university students. 30 participants participated in the exploratory interviews. A total of 12 interviews were conducted during the in-depth stage based on findings in the preceding research.FindingsBased on the qualitative data analysis, a taxonomy was developed. The idea of the taxonomy is summarized in that different dimensions of the avatar are considered the main base (first phase) of the taxonomy. There are consequential three parts: the attitudinal consequences related to the website; the attitudinal consequences related to the brand; the behaviours towards the brand. These behaviours represent the final phase of the taxonomy.Originality/valueBy developing a taxonomy of using avatars on brands' websites, the authors advance the understanding consumer-brands relationships. Using avatars' verbal interactions helps in shaping consumers' cognitive, affective, attitudinal and behavioural responses and add vital empirical evidence to the increasing body of research and practices involving avatar usage in the interactive marketing area

Avatar augmented online conversation

Thesis (Ph. D.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2003.Includes bibliographical references (p. 167-175).One of the most important roles played by technology is connecting people and mediating their communication with one another. Building technology that mediates conversation presents a number of challenging research and design questions. Apart from the fundamental issue of what exactly gets mediated, two of the more crucial questions are how the person being mediated interacts with the mediating layer and how the receiving person experiences the mediation. This thesis is concerned with both of these questions and proposes a theoretical framework of mediated conversation by means of automated avatars. This new approach relies on a model of face-to-face conversation, and derives an architecture for implementing these features through automation. First the thesis describes the process of face-to-face conversation and what nonverbal behaviors contribute to its success. It then presents a theoretical framework that explains how a text message can be automatically analyzed in terms of its communicative function based on discourse context, and how behaviors, shown to support those same functions in face-to-face conversation, can then be automatically performed by a graphical avatar in synchrony with the message delivery. An architecture, Spark, built on this framework demonstrates the approach in an actual system design that introduces the concept of a message transformation pipeline, abstracting function from behavior, and the concept of an avatar agent, responsible for coordinated delivery and continuous maintenance of the communication channel. A derived application, MapChat, is an online collaboration system where users represented by avatars in a shared virtual environment can chat and manipulate an interactive map while their avatars generate face-to-face behaviors.(cont.) A study evaluating the strength of the approach compares groups collaborating on a route-planning task using MapChat with and without the animated avatars. The results show that while task outcome was equally good for both groups, the group using these avatars felt that the task was significantly less difficult, and the feeling of efficiency and consensus were significantly stronger. An analysis of the conversation transcripts shows a significant improvement of the overall conversational process and significantly fewer messages spent on channel maintenance in the avatar groups. The avatars also significantly improved the users' perception of each others' effort. Finally, MapChat with avatars was found to be significantly more personal, enjoyable, and easier to use. The ramifications of these findings with respect to mediating conversation are discussed.by Hannes Högni. Vilhjálmsson.Ph.D

The Effects of Instructor-Avatar Immediacy in Second Life, an Immersive and Interactive 3D Virtual Environment

Growing interest of educational institutions in desktop 3D graphic virtual environments for hybrid and distance education prompts questions on the efficacy of such tools. Virtual worlds, such as Second Life®, enable computer-mediated immersion and interactions encompassing multimodal communication channels including audio, video, and text-. These are enriched by avatar-mediated body language and physical manipulation of the environment. In this para-physical world, instructors and students alike employ avatars to establish their social presence in a wide variety of curricular and extra-curricular contexts. As a proxy for the human body in synthetic 3D environments, an avatar represents a \u27real\u27 human computer user and incorporates default behavior patterns (e.g., autonomous gestures such as changes in body orientation or movement of hands) as well as expressive movements directly controlled by the user through keyboard \u27shortcuts.\u27 Use of headset microphones and various stereophonic effects allows users to project their speech directly from the apparent location of their avatar. In addition, personalized information displays allow users to share graphical information, including text messages and hypertext links. These \u27channels\u27 of information constituted an integrated and dynamic framework for projecting avatar \u27immediacy\u27 behaviors (including gestures, intonation, and patterns of interaction with students), that may positively or negatively affect the degree to which other observers of the virtual world perceive the user represented by the avatar as \u27socially present\u27 in the virtual world. This study contributes to the nascent research on educational implementations of Second Life in higher education. Although education researchers have investigated the impact of instructor immediacy behaviors on student perception of instructor social presence, students\u27 satisfaction, motivation, and learning, few researchers have examined the effects of immediacy behaviors in a 3D virtual environment or the effects of immediacy behaviors manifested by avatars representing instructors. The study employed a two-factor experimental design to investigate the relationship between instructor avatars\u27 immediacy behaviors (high vs. low) and students\u27 perception of instructor immediacy, instructor social presence, student avatars co-presence and learning outcomes in Second Life. The study replicates and extends aspects of an earlier study conducted by Maria Schutt, Brock S. Allen, and Mark Laumakis, including components of the experimental treatments that manipulated the frequency of various types of immediacy behaviors identified by other researchers as potentially related to perception of social presence in face-to-face and mediated instruction. Participants were 281 students enrolled in an introductory psychology course at San Diego State University who were randomly assigned to one of four groups. Each group viewed a different version of the 28-minute teaching session in Second Life on current perspective in psychology. Data were gathered from student survey responses and tests on the lesson content. Analysis of variance revealed significant differences between the treatment groups (F (3,113) = 6.5,p = .000). Students who viewed the high immediacy machinimas (Group 1 HiHi and Group 2 HiLo) rated the immediacy behaviors of the instructor-avatar more highly than those who viewed the low-immediacy machinimas (Group 3 LoHi and Group 4 LoLo). Findings also demonstrate strong correlations between students\u27 perception of instructor avatar immediacy and instructor social presence (r = .769). These outcomes in the context of a 3D virtual world are consistent with findings on instructor immediacy and social presence literature in traditional and online classes. Results relative to learning showed that all groups tested higher after viewing the treatment, with no significant differences between groups. Recommendations for current and future practice of using instructor-avatars include paralanguage behaviors such as voice quality, emotion and prosodic features and nonverbal behaviors such as proxemics and gestures, facial expression, lip synchronization and eye contact
