An Umbrella Review of Reporting Quality in CHI Systematic Reviews: Guiding Questions and Best Practices for HCI

Systematic reviews (SRs) are vital to gathering and structuring knowledge, yet descriptions of their procedures are often inadequate. In human-computer interaction (HCI), SRs are still uncommon but gaining momentum, which prompted us to explore how SRs are reported at CHI—the flagship HCI conference venue. To assess the reporting quality of CHI reviews that aim for a systematic approach, we conducted an umbrella review and applied reporting guidelines for SRs (PRISMA and ENTREQ) to our corpus. We contribute the first exploration of how well SRs at CHI meet guidelines for reporting quality, showcasing strategies for improvement in reporting and conducting SRs especially in the domains of appraisal, synthesis, and documentation (i.e., protocol development). Finally, we present guiding questions for HCI researchers and practitioners for reporting SRs, as well as suggestions for best practices.

DEEP LEARNING BASED EMOTION DETECTION SYSTEM

Emotion detection plays a crucial role in human-computer interaction, affective computing, and psychological research. Traditional methods of emotion detection often rely on manual annotations or subjective assessments, which can be time- consuming and prone to biases. In this paper, we propose a Deep Learning-Based Emotion Detection System that leverages advanced neural network architectures to automatically recognize emotions from facial expressions in real-time. The system utilizes convolutional neural networks (CNNs) for feature extraction from facial images and recurrent neural networks (RNNs) for sequence modeling of temporal dynamics in facial expressions. Our proposed system addresses key challenges in emotion detection, including variations in facial expressions, lighting conditions, and occlusions. By training on large-scale datasets of labeled facial images, the system learns to accurately classify emotions into predefined categories such as happiness, sadness, anger, fear, disgust, and surprise. We evaluate the performance of the system using standard metrics such as accuracy, precision, recall, and F1-score, demonstrating its effectiveness in real- world scenarios. The results indicate that the Deep Learning-Based Emotion Detection System achieves state-of-the-art performance in recognizing emotions from facial expressions, outperforming traditional methods. The system's ability to analyze facial dynamics in real-time opens up opportunities for applications in human-computer interaction, virtual reality, mental health monitoring, and personalized user experiences.

EEG Emotion Recognition Network Based on Attention and Spatiotemporal Convolution.

Human emotions are complex psychological and physiological responses to external stimuli. Correctly identifying and providing feedback on emotions is an important goal in human-computer interaction research. Compared to facial expressions, speech, or other physiological signals, using electroencephalogram (EEG) signals for the task of emotion recognition has advantages in terms of authenticity, objectivity, and high reliability; thus, it is attracting increasing attention from researchers. However, the current methods have significant room for improvement in terms of the combination of information exchange between different brain regions and time-frequency feature extraction. Therefore, this paper proposes an EEG emotion recognition network, namely, self-organized graph pesudo-3D convolution (SOGPCN), based on attention and spatiotemporal convolution. Unlike previous methods that directly construct graph structures for brain channels, the proposed SOGPCN method considers that the spatial relationships between electrodes in each frequency band differ. First, a self-organizing map is constructed for each channel in each frequency band to obtain the 10 most relevant channels to the current channel, and graph convolution is employed to capture the spatial relationships between all channels in the self-organizing map constructed for each channel in each frequency band. Then, pseudo-three-dimensional convolution combined with partial dot product attention is implemented to extract the temporal features of the EEG sequence. Finally, LSTM is employed to learn the contextual information between adjacent time-series data. Subject-dependent and subject-independent experiments are conducted on the SEED dataset to evaluate the performance of the proposed SOGPCN method, which achieves recognition accuracies of 95.26% and 94.22%, respectively, indicating that the proposed method outperforms several baseline methods.

EmoSonics: Emotion Detection via Voice and Speech Recognition

Understanding emotions from speech is like deciphering a rich tapestry of human expression in the realm of human-computer interaction. It's akin to listening to someone's tone and inflection to discern whether they're happy, surprised, or experiencing a range of other feelings. Researchers use a variety of techniques, from analyzing speech patterns to utilizing advanced technologies like fMRI, to decode these emotional cues. Emotions aren't just simple labels; they're complex and nuanced, demanding sophisticated methods for accurate interpretation. Some methods break emotions down into simple categories, while others embrace the intricacies of human emotion, treating them as continuous variables. Ultimately, the goal is to enhance communication between humans and computers by enabling machines to understand and respond appropriately to our emotional states. This pursuit underscores the significance of emotion detection in speech analysis and highlights the need for continually evolving methodologies in human-computer interaction research.

We see an opportunity for research in Human-Computer Interaction (HCI) in the development of these devices. Neurotechnology offers new insights into user experiences and facilitates the development of novel methods in HCI. Researchers will be able to create innovative interactive systems based on the ability to measure cognitive activity at scale in real-world settings. In this paper, we contribute a vision of how neurotechnology will transform HCI research and practice. We discuss how neurotechnology prompts a discussion about ethics, privacy, and trust. This trend highlights HCI’s crucial role in ensuring that neurotechnology is developed and utilised in ways that truly benefit people.

Pilot study of the relation between various dynamics of avatar experience and perceptual characteristics

In recent years, due to the prevalence of virtual reality (VR) and human-computer interaction (HCI) research, along with the expectation that understanding the process of establishing sense of ownership, sense of agency, and limb heaviness (in this study, limb heaviness is replaced with comfort level) will contribute to the development of various medical rehabilitation, various studies have been actively conducted in these fields. Previous studies have indicated that each perceptual characteristics decrease in response to positive delay. However, it is still unclear how each perceptual characteristic changes in response to negative delay. Therefore, the purpose of this study was to deduce how changes occur in the perceptual characteristics when certain settings are manipulated using the avatar developed in this study. This study conducted experiments using an avatar system developed for this research that uses electromyography as the interface. Two separate experiments involved twelve participants: a preliminary experiment and a main experiment. As observed in the previous study, it was confirmed that each perceptual characteristics decreased for positive delay. In addition, the range of the preliminary experiment was insufficient for the purpose of this study, which was to confirm the perceptual characteristics for negative delay, thus confirming the validity of conducting this experiment. Meanwhile, the main experiment showed that the sense of ownership, sense of agency, and comfort level decreased gradually as delay time decreased, (i.e., this event is prior to action with intention, which could not be examined in the previous study). This suggests that control by the brain-machine interface is difficult to use when it is too fast. In addition, the distribution of the most strongly perceived settings in human perceptual characteristics was wider in regions with larger delays, suggesting this may lead to the evaluation of an internal model believed to exist in the human cerebellum. The avatar developed for this study may have the potential to create a new experimental paradigm for perceptual characteristics.

User accounts: How technological concepts permeate public law through the EU's AI Act

This article argues that through the EU's technology regulation, technological concepts permeate legal language. Such concepts may function as transplants, even irritants, causing tensions and uncertainties. As technology regulation is increasingly horizontal, i.e. obligating private and public actors alike, these newfound legal concepts remain disconnected from established public law vocabulary and the power constellations it represents and embeds. We approach this evolution of legal language from public law perspective and concentrate on the concepts of ‘user’ and ‘deployer’ in the EU's upcoming Artificial Intelligence Act. We discuss these emerging legal concepts in relation to the rich theorizing on the concepts in human–computer interaction research. Our analysis demonstrates a discrepancy between legal and technology-oriented conceptualizations of the ‘user-deployer’. We draw three conclusions. First, the digital revolution is taking place in conceptual-linguistic practices of law, and not only when translating law into code. Second, when external concepts are appropriated into law, they are uprooted from their established habitat, which may result in unpredictability in future legal interpretation. Third, in public law, adopting the ‘user-deployer’ may have some additional challenges, as it introduces a new agent into the relationship between public authority and private entities. Simultaneously, citizens seem to be mainly excluded from the legal conceptualizing, which risks blurring traditional power constellations.

Conducting Research at the Intersection of HCI and Health: Building and Supporting Teams with Diverse Expertise to Increase Public Health Impact.

Research at the intersection of human-computer interaction (HCI) and health is increasingly done by collaborative cross-disciplinary teams. The need for cross-disciplinary teams arises from the interdisciplinary nature of the work itself-with the need for expertise in a health discipline, experimental design, statistics, and computer science, in addition to HCI. This work can also increase innovation, transfer of knowledge across fields, and have a higher impact on communities. To succeed at a collaborative project, researchers must effectively form and maintain a team that has the right expertise, integrate research perspectives and work practices, align individual and team goals, and secure funding to support the research. However, successfully operating as a team has been challenging for HCI researchers, and can be limited due to a lack of training, shared vocabularies, lack of institutional incentives, support from funding agencies, and more; which significantly inhibits their impact. This workshop aims to draw on the wealth of individual experiences in health project team collaboration across the CHI community and beyond. By bringing together different stakeholders involved in HCI health research, together, we will identify needs experienced during interdisciplinary HCI and health collaborations. We will identify existing practices and success stories for supporting team collaboration and increasing HCI capacity in health research. We aim for participants to leave our workshop with a toolbox of methods to tackle future team challenges, a community of peers who can strive for more effective teamwork, and feeling positioned to make the health impact they wish to see through their work.

Using generative AI in human resource development: an applied research study

ABSTRACT In this article, we report results of an experimental study investigating the use of ChatGPT in the design of an HRD intervention. Our goal was to identify the benefits and drawbacks of using this technology in HRD practice. The theoretical framework for the study was provided by the Activity Theory, an often used approach in Human-Computer Interaction research. The study participants were HRD doctoral students from two large public universities in the USA. The participants used ChatGPT in developing an HRD intervention plan, based on a supplied organisational scenario. Data for the analysis included the intervention plans, prompts used by participants, outputs received from ChatGPT, and participants’ responses to open-ended questions. The study revealed varied participant experiences with ChatGPT, including differences in time investment and interaction rules. Among key findings were the tendency to interact with ChatGPT as if it were a human consultant, and steps to establish division of labour between the tool and the human agent. ChatGPT was valued for its usefulness in initial planning and brainstorming ideas for HRD interventions, yet its limitations were apparent in generic responses and lack of contextual understanding. Across all participants, the crucial role of human expertise in refining ChatGPT’s output was consistently highlighted.

Towards more trusted virtual physicians: the combinative effects of healthcare chatbot design cues and threat perception on health information trust

ABSTRACT Although virtual healthcare assistants have been extensively adopted in the healthcare industry, users still question their reliability. Based on the Computers are Social Actor (CASA) paradigm, the current study conducted an experiment to examine how different chatbot design cues (Chatbot vs. Layperson vs. Doctor) affect users’ trust towards virtual healthcare assistants. Results indicate that the doctor-like design cues and bot-like design cues (vs. layperson-like design cues) elicited significantly greater perceived chatbot expertise, which enhanced users’ trust in health information. This study further found the significant moderating effects of users’ perceived threat on chatbot expertise and privacy concerns. Positive effects of the doctor-like design cue and the bot-like design cue on perceived expertise were found to be significant only for those whose perceived threat was high. Interestingly, the doctor-like design cues led to greater (less) privacy concerns when the perceived threat level was low (high). The findings provide human–computer interaction researchers and chatbot UX/UI designers with important theoretical and practical implications.

In personal identity recognition systems, detecting a person's age, gender, and language using voice signal characteristics is a crucial issue, especially because of the importance of security considerations. Age, gender, and language classification problems are important in signal processing because they are used to analyze and understand human behavior, interactions, and preferences. This can be especially useful in the fields of human-computer interaction, psychology, and social science research. In this paper, a new system for detecting a speaker's age, gender, and language based on deep learning models is presented. Deep learning models have shown great efficacy in various fields of signal processing. For this paper, a range of deep models were tested, including convolutional neural networks (CNNs), recurrent neural network (RNN), and a fine-tuning ResNet34 architecture. Additionally, techniques such as transfer learning were applied to improve the efficiency of the proposed system. The input voice signals are preprocessed by applying the spectro-temporal transform to obtain additional features that can be fed to the ResNet34 model, which is designed specifically for the task of voice signal processing. The dataset used in this paper was sourced from the Mozilla common voice initiative, which is dedicated to advancing speech recognition and language identification technologies. The performance of the proposed algorithm was evaluated in the presence of Gaussian noise to determine its robustness. The experimental results demonstrated that the proposed algorithm significantly outperformed basic algorithms and other deep neural networks in terms of age and gender recognition from voice signals.
