Adaptive Real-Time Emotion Recognition from Body Movements
Weiyi Wang, Valentin Enescu, Hichem Sahli
Article No.: 18
DOI: 10.1145/2738221

We propose a real-time system that continuously recognizes emotions from body movements. The combined low-level 3D postural features and high-level kinematic and geometrical features are fed to a Random Forests classifier through summarization...

The MovieLens Datasets: History and Context
F. Maxwell Harper, Joseph A. Konstan
Article No.: 19
DOI: 10.1145/2827872

The MovieLens datasets are widely used in education, research, and industry. They are downloaded hundreds of thousands of times each year, reflecting their use in popular press programming books, traditional and online courses, and software. These...

A Process for Systematic Development of Symbolic Models for Activity Recognition
Kristina Yordanova, Thomas Kirste
Article No.: 20
DOI: 10.1145/2806893

Several emerging approaches to activity recognition (AR) combine symbolic representation of user actions with probabilistic elements for reasoning under uncertainty. These approaches provide promising results in terms of recognition performance,...

“I’ll Be There Next”: A Multiplex Care Robot System that Conveys Service Order Using Gaze Gestures
Keiichi Yamazaki, Akiko Yamazaki, Keiko Ikeda, Chen Liu, Mihoko Fukushima, Yoshinori Kobayashi, Yoshinori Kuno
Article No.: 21
DOI: 10.1145/2844542

In this article, we discuss our findings from an ethnographic study at an elderly care center where we observed the utilization of two different functions of human gaze to convey service order (i.e., “who is served first and who is served...

Generating Robot Gaze on the Basis of Participation Roles and Dominance Estimation in Multiparty Interaction
Yukiko I. Nakano, Takashi Yoshino, Misato Yatsushiro, Yutaka Takase
Article No.: 22
DOI: 10.1145/2743028

Gaze is an important nonverbal feedback signal in multiparty face-to-face conversations. It is well known that gaze behaviors differ depending on participation role: speaker, addressee, or side participant. In this study, we focus on dominance as...
