How Low Should You Go? Low Response Rates and the Validity of Inference in IS Questionnaire Research

Stephen Sivo, Carol Saunders, Qing Chang, James Jiang
2006 Journal of the AIS  
To illustrate how nonresponse error may bias findings in IS research, we calculate its impact on confidence intervals.  ...  We believe IS researchers can and should do a better of job of improving (assuring) the validity of their findings by minimizing nonresponse error.  ...  This is especially true of e-mail and web-based questionnaires that can reach a large number of people with the touch of a key.  ...

"It wasn't me, was it?" Plagiarism and the Web

Dànielle DeVoss, Annette C. Rosati
2002 Computers and Composition  
Issues of plagiarism are complex, and made all the more complicated by students' increasing use of the World Wide Web as a research space.  ...  We share these examples to explore how issues related to plagiarism and its effects are both reproduced and change in new research spaces.  ...  There are a variety of practical, critical, writing-rich ways to engage students in web-based research and evaluation.  ...

Manipulating perceived social presence through the web interface and its impact on attitude towards online shopping

Khaled Hassanein, Milena Head
2007 International Journal of Human-Computer Studies  
This paper explores how human warmth and sociability can be integrated through the web interface to positively impact consumer attitudes towards online shopping.  ...  Electronic commerce typically lacks human warmth and sociability, since it is more impersonal, anonymous and automated than traditional face-to-face commerce.  ...  Acknowledgments This research was partially funded by research grants from the National Engineering and Research Council (NSERC) of Canada.  ...

One-Shot Free-View Neural Talking-Head Synthesis for Video Conferencing [article]

Ting-Chun Wang, Arun Mallya, Ming-Yu Liu
2021 arXiv   pre-print
We propose a neural talking-head video synthesis model and demonstrate its application to video conferencing.  ...  Our motion is encoded based on a novel keypoint representation, where the identity-specific and motion-related information is decomposed unsupervisedly.  ...  We thank Jan Kautz for his valuable comments throughout the development of the work.  ...

Turning away from talking heads

Bonnie A. Nardi, Heinrich Schwarz, Allan Kuchinsky, Robert Leichner, Steve Whittaker, Robert Sclabassi
1993 Proceedings of the SIGCHI conference on Human factors in computing systems - CHI '93  
To date, most research on the value of video has concentrated on "taLking heads" video in which the video images are of remote participants conferring or performing some task together.  ...  In contrast to talking heads video, we studied video-as-data in which video images of the workspace and work objects are the focus of interest, and convey criticat information about the work.  ...  Steve Gate's previous work on the project was of great value.  ...

Optimization of an Image-Based Talking Head System

Kang Liu, Joern Ostermann
2009 EURASIP Journal on Audio, Speech, and Music Processing  
This paper presents an image-based talking head system, which includes two parts: analysis and synthesis.  ...  A critical issue of the synthesis is the unit selection which selects and concatenates these appropriate mouth images from the database such that they match the spoken words of the talking head.  ...  The authors would like to thank Tobias Elbrandt for his helpful comments and suggestions in the evaluation of the subjective tests.  ...

Corpus-based generation of head and eyebrow motion for an embodied conversational agent

Mary Ellen Foster, Jon Oberlander
2007 Language Resources and Evaluation  
We present a system that uses corpus-based selection strategies to specify the head and eyebrow motion of an animated talking head.  ...  We then present two different methods of selecting motions for the talking head based on the corpus data: one that chooses the majority option in all cases, and one that makes a weighted choice among all  ...  In this project, we select the head and eyebrow motions of a synthetic talking head in a multimodal dialogue system based on the recorded and annotated behaviour of a speaker reading a script of similar  ...

Peter Wiemer-Hastings, David Allbritton, Elizabeth Arnott
2004 Lecture Notes in Computer Science  
Its modular architecture enables the interchange and evaluation of different tools and techniques for improving tutoring.  ...  In this paper, we describe the RMT architecture and give the results of an initial experiment that compared RMT's animated agent "talking head" with a text-only version of the system.  ...  Because RMT is a web-based system, each tutoring session has its own dialog manager, and the DM maintains information about the parameters of the tutoring session and the current state of the dialog.  ...
