Abstract [en]

Distance communication is becoming an important part of our lives because of the current advancement in computer mediated communication (CMC). Despite the current advancement in CMC especially video teleconferencing; it is still far from face-to-face (FtF) interaction. This study will focus on the advancements in video teleconferencing; their trends and challenges. Furthermore, this work will present an overview of previously developed hardware and software techniques to improve the video teleconferencing experience. After discussing the background development of video teleconferencing, we will propose an intuitive solution to improve the video teleconferencing experience. To support the proposed solution, the Embodied Interaction based distance communication framework is developed. The effectiveness of this framework is validated by the user studies. To summarize this work has considered the following questions: What are the factors which make video teleconferencing different from face to face interaction?; What researchers have done so far to improve video teleconferencing?; How to further improve the teleconferencing experience?; How to add more non-verbal modalities to enhance the video teleconferencing experience? At the end we have also provided the future directions for embodied interaction based video teleconferencing.

Abstract [en]

During face-to-face meetings, humans use multimodal information, including verbal information, visual information, body language, facial expressions, and other non-verbal gestures. In contrast, during computer-mediated-communication (CMC), humans rely either on mono-modal information such as text-only, voice-only, or video-only or on bi-modal information by using audiovisual modalities such as video teleconferencing. Psychologically, the difference between the two lies in the level of the subjective experience of presence, where people perceive a reduced feeling of presence in the case of CMC. Despite the current advancements in CMC, it is still far from face-to-face communication, especially in terms of the experience of presence.

This thesis aims to introduce new concepts, theories, and technologies for presence design where the core is actions for creating presence. Thus, the contribution of the thesis can be divided into a technical contribution and a knowledge contribution. Technically, this thesis details novel technologies for improving presence experience during mediated communication (video teleconferencing). The proposed technologies include action robots (including a telepresence mechatronic robot (TEBoT) and a face robot), embodied control techniques (head orientation modeling and virtual reality headset based collaboration), and face reconstruction/retrieval algorithms. The introduced technologies enable action possibilities and embodied interactions that improve the presence experience between the distantly located participants. The novel setups were put into real experimental scenarios, and the well-known social, spatial, and gaze related problems were analyzed.

The developed technologies and the results of the experiments led to the knowledge contribution of this thesis. In terms of knowledge contribution, this thesis presents a more general theoretical conceptual framework for mediated communication technologies. This conceptual framework can guide telepresence researchers toward the development of appropriate technologies for mediated communication applications. Furthermore, this thesis also presents a novel strong concept – presence through actions - that brings in philosophical understandings for developing presence- related technologies. The strong concept - presence through actions is an intermediate-level knowledge that proposes a new way of creating and developing future 'presence artifacts'. Presence- through actions is an action-oriented phenomenological approach to presence that differs from traditional immersive presence approaches that are based (implicitly) on rationalist, internalist views.
