Special issue on subtle expressivity for characters and robots
نویسندگان
چکیده
This special issue is devoted to theoretical and empirical studies of subtle expressivity for characters and robots. People both consciously and subconsciously use subtle expressions to communicate their emotions and intentions through variations in gaze direction, voice tone and gesture speed. People also perceive changes in the internal states of others from subtle changes in such expressivities while interacting with them. Subtle expressivity is generally regarded as playing a supporting part to the leading role of explicit expressivity, such as the contents of speech and voice prosody. However, under some circumstances subtle expressive cues take precedence, e.g. expressing emotion. The human–computer interaction research community has come to recognize lifelikeness and personality as important objectives of software design in seeking to reduce cognitive load. However, we are far from having a coherent understanding of what subtle expressivity actually is and how products and processes can utilize it. We might question whether designing for subtle expressivity will actually result in gentle emotional effects on the users and whether the processes and issues involved differ in any significant way from designing for believability or personality. The basic idea for this special issue is a result of the CHI2003 workshop we organized in Ft. Lauderdale, Florida. In response to a general call for papers, we received a wealth of submissions, demonstrating the keen interest of researchers and designers in this area. The many high-quality submissions resulted in the publication of a total of eight papers, six on screen characters and two on robotics characters. We would like to thank all of the authors who helped create this special issue. As a last remark, we would like to thank the previous Editor-in-Chief, Dr. Brian Gaines, the current Editor-in-Chief, Dr. Susan Wiedenbeck, the Journal Manager, Dr. Fred Kop, and their colleagues for their great support in the process of editing this special issue. We also appreciate the Review Committees, who helped the authors revise their papers. The Review Committees:

Silence, Murmurs and Applause: Reflections on Expressions of Collections
The area of commonality has to do with the issue of subtle expressivity. I am interested in means—particularly as manifested in visual and auditory portrayals—of conveying complex and subtle expressions. And much of my work draws upon studies—principally from sociology—of the ways in which people notice and interpret large arrays of subtle cues expressed by ‘natural systems.’ The area of differ...
متن کاملUsing human physiology to evaluate subtle expressivity of a virtual quizmaster in a mathematical game
The aim of the experimental study described in this article is to investigate the effect of a lifelike character with subtle expressivity on the affective state of users. The character acts as a quizmaster in the context of a mathematical game. This application was chosen as a simple, and for the sake of the experiment, highly controllable, instance of human–computer interfaces and software. Su...
متن کاملSubtle Expressivity of Characters and Robots
A Robotic Computer, which moves its monitor "head" and "neck" but has no explicit face, is being designed to interact with users in a natural way for applications such as learning, rapport-building, interactive teaching, and posture improvement. In all these applications, the robot will need to move in subtle ways that express its state, and that promote appropriate movements in the user, but t...
متن کاملNonlinear Stabilizing Controller for a Special Class of Single Link Flexible Joint Robots
Joint flexibility is a very important factor to consider in the controller design for robot manipulators if high performance is expected. Most of the research works on control of flexible-joint robots in literature have ignored the actuator dynamics to avoid complexity in controller design. The problem of designing nonlinear controller for a class of single-link flexible-joint robot manipulator...
