Recognition of Head-Movement Functions in Conversations Using Verbal Features
KIDO Yusei, SUGIYAMA Shunta, OTSUKA Kazuhiro
J107-A ( 1 ) 6 - 18 2024.1 [Reviewed]
Language：Japanese Publishing type：Research paper (scientific journal) Publisher：The Institute of Electronics, Information and Communication Engineers Joint Work
To recognize the functions of head movements in conversations, this paper proposed novel models that integrate conversation participants' verbal and nonverbal behavioral features. As the nonverbal features, these models employ embedding vectors from the CNNs, which have been previously proposed to recognize the head-movement functions. As the verbal features, we examine three representations based on BERT-based embedding vectors in terms of their temporal granularity. Then, a forward neural network integrates these feature vectors to decide the presence or absence of each head-movement function at each time frame in the conversation. The experiments confirmed the proposed model outperformed the previous ones and improved the F-measure by 10.4 points at maximum for a back-channel function.

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：The Institute of Electronics, Information and Communication Engineers Joint Work
This paper proposes machine-learning models for recognizing the gaze functions in conversations. For that purpose, we first created a functional gaze corpus with 43 functions, including monitoring, regulation, and expressiveness. Targeting frequent gaze functions, we propose several models using convolutional neural networks (CNNs), which input the multimodal features, including head pose, utterance/silence status, gaze/avert status, eyeball direction, and facial expression. Experimental results confirmed the potentials of the proposed models, which improved the average F-score for 14 functions by 0.243 at maximum and can recognize a gaze function called “looking while listening,” with the F value of 0.839.

Deep Regression Models for Estimating Ambiguity in Functional Interpretations of Head Movements in Conversations
TAKEDA Kazuki, IMAMURA Mai, OTSUKA Kazuhiro
J106-A ( 10 ) 255 - 266 2023.6 [Reviewed]
Language：Japanese Publishing type：Research paper (scientific journal) Publisher：The Institute of Electronics, Information and Communication Engineers Joint Work
Head movements play essential roles in human conversations and entail intrinsic ambiguities in expressing and perceiving. This paper proposes regression models for estimating the degree of ambiguities in the head-movement function of conversation participants. As the ambiguities, we introduced expressional perceptibility and interpretational diversity, which are defined as the average and standard deviation of the ratings of multiple observers, respectively. This paper proposes convolutional neural networks, which simultaneously estimate both ambiguities, called μ-σ CNNs. The experiments compared the μ-σ CNNs with other models, which independently estimate each of the ambiguities, and confirmed that the μ-σ CNNs have potential to outperform the other models.

Analyzing Effects of Kinetic Reproduction of Head Movements on Functional Interactions among Remote Meeting Participants
MARUYAMA Mitsuki, MORI Takashi, OTSUKA Kazuhiro
J106-A ( 3 ) 88 - 103 2023.3 [Reviewed]
Language：Japanese Publishing type：Research paper (scientific journal) Publisher：The Institute of Electronics, Information and Communication Engineers Joint Work
From the functional aspects of head movements, this paper reveals the effects of how the mechanical reproduction of participants' head movements facilitates the interactions among participants in a telepresence system called the MMSpace. The MMSpace recreates the head movements of each remote participant by mechanically controlling the position and pose of the panel that displays the participant's face. We created a functional head-movement corpus of MMSpace-based meetings and analyzed the (co-)occurrence frequencies of the functions that appeared in the meeting with/without mechanical panel motion. The results show that the mechanically augmented head movements significantly improved the functional interactions such as between the speaker's rhythmic movements and the listener's back-channel movements.

Recognition of Synergetic Functions between Head Movements and Facial Expressions in Conversations
IMAMURA Mai, TAKEDA Kazuki, KUMANO Shiro, OTSUKA Kazuhiro
J106-A ( 3 ) 70 - 87 2023.3 [Reviewed]
Language：Japanese Publishing type：Research paper (scientific journal) Publisher：The Institute of Electronics, Information and Communication Engineers Joint Work
This paper proposes machine-learning models for recognizing the synergetic functions between facial expressions and head movements in conversations. To discover such synergetic functions, we built a functional facial-expression corpus, which includes various facial functions beyond the affect display, and analyzed it with the functional head-movement corpus. The analysis revealed some types of synergetic relationships between the facial expressions and head movements, including reinforcement, multiplexing, and complement. To recognize such synergetic functions, we build several models using convolutional neural networks (CNNs), which input facial action-unit and head-pose sequences. The experiment results confirmed the potential of the proposed models.

Prediction of Participant's Subjective Impressions based on Head-Movement Functions in Multiparty Conversations
OTSUCHI Shumpei, ISHII Yoko, NAKATANI Momoko, OTSUKA Kazuhiro
J105-D ( 9 ) 504 - 517 2022.9 [Reviewed]
Language：Japanese Publishing type：Research paper (scientific journal) Joint Work
This paper proposes novel prediction models for the subjective impressions of meeting participants, based on their head-movement functions. The goal is to estimate the self-rated impression scores on the impression items consisting of `atmosphere,' `enjoyment,' `willingness,' and `concentration,' which were rated every two-minute intervals in the meetings. The prediction model employs Random-Forest regressors that input head-movement function features based on 10 head-movement functions detected with convolutional neural networks using head pose sequences measured in the meeting videos. The experiment results show the models' predictability and reveal the relationship between the impressions and the participants' behaviors.

Recognizing Functional Interactions via Head Movements by Deep Transfer Learning in Multiparty Conversations

J105-A ( 10 ) 111 - 124 2022.6 [Reviewed]
Language：Japanese Publishing type：Research paper (scientific journal) Publisher：The Institute of Electronics, Information and Communication Engineers Single Work
In group meetings, the participant's head movements play various functions. This study extends the concept of individual head-movement function (HMF) to interactional functions between the speaker and listener in meetings. We propose strategies to transfer the existing CNN-based HMF recognition model into the interactional models that can recognize the interactional functions better than the simple logical-product decision of two individual CNN models. The transfer strategies include a distributed representation of multiple HMFs, called a functional spectrum vector extracted from the CNNs' middle layers. The experiments confirmed that the transferred models outperformed the logical-product-based model up to 13.9 points in F-score.

Explainable Models for Predicting Interlocuters' Subjective Impressions based on Nonverbal Functional Features

Proceedings of the Annual Conference of JSAI JSAI2022 ( 0 ) 3H3OS12a05 - 3H3OS12a05 2022
Language：Japanese Publishing type：Research paper (scientific journal) Publisher：The Japanese Society for Artificial Intelligence Joint Work
<p>An explainable framework is proposed to predict the interlocutors' subjective impressions in group meetings. The goal is to explain when and what kind of nonverbal behaviors affected interlocutors' impressions during meetings. To that end, we formulate a two-fold framework consisting of the regression models of interlocutors' impression scores based on functional head-movement features, followed by the estimation of the temporal distribution of SHAP-based feature contribution, which is obtained with the kernel density estimation of the temporal occurrence probabilities of head-movement functions. The former stage identifies the behaviors related to the impressions, and the later stage suggests the timing of the behaviors, by locating the maximum point of the temporal feature contribution curve, based on an assumption that temporary intensive behaviors lead to form a strong impression. This report shows preliminary results and analyses applied to 4-party 17-group discussions.</p>

Recognizing Head-Movement Functions in Conversations by Using Feature Inflation-Deflation Networks
TAKEDA Kazuki, OTSUKA Kazuhiro
J105-A ( 2 ) 26 - 37 2021.9 [Reviewed]
Language：Japanese Publishing type：Research paper (scientific journal) Publisher：The Institute of Electronics, Information and Communication Engineers Joint Work
A new deep neural network module called an Inflation-Deflation (I/DeF) module is proposed to improve the recognition performance of the head-movement functions in group meetings, using Convolutional Neural Networks (CNNs). To facilitate the learning of the temporal features in the short windowed input head-movement sequence, the I/DeF module repeatedly cascades an inflation process and a deflation process. The former extends the input sequence in terms of its scale and temporal dimensions using a transposed convolution. The deflation process reduces and restores the data dimensions by using convolution. The experiments confirmed that I/DeF-integrated CNNs and other DNNs outperformed the existing DNNs.
