The construction of a natural interactive human-computer interaction has become an integral component of intelligent system development, constituting a core subject within the field of human-computer interaction. Grounded in the utilization of human perception theories, this study proposes a robust method for speech emotion recognition and a model for inferring user emotional state changes, thereby achieving a hu-man-computer interaction experience characterized by both listening and articulating, and conveying sentiments effectively. Simultaneously, focusing on the audio-visual modalities within human-computer interaction, this research explores methods for con-structing interactive feedback in auditory and visual modalities within real hu-man-computer dialog scenarios. This aims to synchronize textual, verbal, and visual expressions in human-computer interaction, enhancing its naturalness, improving user experience, and augmenting satisfaction and pleasure during interaction. The research contributions are as follows: Introducing a method that robustly identifies user emotional states in real hu-man-computer speech dialogue scenarios through the utilization of local and global attention mechanisms. This method generates robust and distinguishable representa-tions of speech emotion, thereby enhancing the robustness and accuracy of speech emotion recognition systems in authentic dialogue scenarios.
Perspectives on Human-Computer Interaction Research with Older People
This book promotes a critical reflection about the research conducted so far in Human-Computer Interaction (HCI) with older people, whose predominant perspective focuses on decline, health, and help. It introduces a new (or different) perspective, which is grounded in interdisciplinary research on older people and digital technologies. Key elements are to (i) address topics that include, but also go beyond decline, health, and help, such as leisure, fun, creativity and culture, to delve more deeply into the role of digital technologies in multiple facets of older people’s lives; (ii) focus on doing research and designing technologies with and for older adults, and their communities, to avoid and fight against negative social conceptions of ageing; and (iii) examine older people’s life course, strengths, interests, and values, as well as their limitations and needs, to design technologies that not only help but also empower them, extending their abilities and acquiring new knowledge, beyond technology use. This perspective aims to help us better understand, design, and evaluate older people’s interactions with digital technologies in the early 21st century.
Advances in Multimodal Interfaces - ICMI 2000
Multimodal Interfaces represents an emerging interdisciplinary research direction and has become one of the frontiers in Computer Science. Multimodal interfaces aim at efficient, convenient and natural interaction and communication between computers (in their broadest sense) and human users. They will ultimately enable users to interact with computers using their everyday skills. These proceedings include the papers accepted for presentation at the Third International Conference on Multimodal Interfaces (ICMI 2000) held in Beijing, China on 1416 O ctober 2000. The papers were selected from 172 contributions submitted worldwide. Each paper was allocated for review to three members of the Program Committee, which consisted of more than 40 leading researchers in the field. Final decisions of 38 oral papers and 48 poster papers were made based on the reviewers’ comments and the desire for a balance of topics. The decision to have a single track conference led to a competitive selection process and it is very likely that some good submissions are not included in this volume. The papers collected here cover a wide range of topics such as affective and perceptual computing, interfaces for wearable and mobile computing, gestures and sign languages, face and facial expression analysis, multilingual interfaces, virtual and augmented reality, speech and handwriting, multimodal integration and application systems. They represent some of the latest progress in multimodal interfaces research.
