    This dissertation reports on the industrial design of a wearable computational device created to enable better emergency medical intervention for situations where electronic remote assistance is necessary. The design created for this doctoral project, which assists practices by paramedics with mandates for search-and-rescue (SAR) in hazardous environments, contributes to the field of human-mediated teleparamedicine (HMTPM). Ethnographic and industrial design aspects of this research considered the intricate relationships at play in search-and-rescue operations, which lead to the design of the system created for this project known as WEHST: Wearable Engine for Human-Mediated Telepresence. Three case studies of different teams were carried out, each focusing on making improvements to the practices of teams of paramedics and search-and-rescue technicians who use combinations of ambulance, airplane, and helicopter transport in specific chemical, biological, radioactive, nuclear and explosive (CBRNE) scenarios. The three paramedicine groups included are the Canadian Air Force 442 Rescue Squadron, Nelson Search and Rescue, and the British Columbia Ambulance Service Infant Transport Team. Data was gathered over a seven-year period through a variety of methods including observation, interviews, examination of documents, and industrial design. The data collected included physiological, social, technical, and ecological information about the rescuers. Actor-network theory guided the research design, data analysis, and design synthesis. All of this leads to the creation of the WEHST system. As identified, the WEHST design created in this dissertation project addresses the difficulty case-study participants found in using their radios in hazardous settings. As the research identified, a means of controlling these radios without depending on hands, voice, or speech would greatly improve communication, as would wearing sensors and other computing resources better linking operators, radios, and environments. WEHST responds to this need. WEHST is an instance of industrial design for a wearable “engine” for human-situated telepresence that includes eight interoperable families of wearable electronic modules and accompanying textiles. These make up a platform technology for modular, scalable and adaptable toolsets for field practice, pedagogy, or research. This document details the considerations that went into the creation of the WEHST design

    This document reports on a NASA-STDP effort to address research interests of the NASA Kennedy Space Center (KSC) through a study entitled, Ground Robotic-Hand Applications for the Space Program (GRASP). The primary objective of the GRASP study was to identify beneficial applications of specialized end-effectors and robotic hand devices for automating any ground operations which are performed at the Kennedy Space Center. Thus, operations for expendable vehicles, the Space Shuttle and its components, and all payloads were included in the study. Typical benefits of automating operations, or augmenting human operators performing physical tasks, include: reduced costs; enhanced safety and reliability; and reduced processing turnaround time

    Developing and evaluating an embodied telepresence system for a real-world context

    This thesis is based on the field trial of a telepresence system. My ambition was to design in a user-centred, collaborative process, a system with simple, embodied control. Elementary in my approach was that the input of the end users extended to the implementation phase, where they could familiarize themselves with an application. A flexible design method allows continuous adaption of the system until the final deployment. I decided to call the design approach I applied in this study conjoint control. In cooperation with experts in the field of telepresence and remote control of camera systems, whilst also drawing on the worldwide communities of open source programmers and maker culture, the system was built in several design cycles. I subsequently performed a field trial of the system when it was used in an office environment for six months. Theoretically, the study is grounded in a number of concepts in the HCI field. One of the central ideas is calm technology, advocating a selective, calm approach in our interaction with computers. This study is furthermore inspired by the tangible user interfaces (TUI) concept, that proposes interaction with computers through the physical environment, rather than through screens, keyboards and mice. A more recent theoretical framework that influenced this study is somaesthetic interaction design, that involves our complete body in interaction with computers and advocates more tranquil interaction models with limited functionality. The results of this study indicate that the design approach of conjoint control generates a good user experience and a high acceptance level. Furthermore, the collaborative design process and the extensive, playful, implementation phase had a positive effect on the validation of users of the system. I conclude in this thesis that conjoint control is a viable approach for the design of a specific area of interactive systems. Simple, physical interaction, based on a collaborative design process with experts and user groups, with a tight coupling to the functionality, could be embraced as a future direction for HCI

    Evoking presence through creative practice on Pepper's ghost displays.

    This thesis proposes a theoretic framework for the analysis of presence research in the context of Pepper’s ghost. Pepper’s ghost as a media platform offers new possibilities for performances, real-time communication and media art. The thesis gives an overview on the 150 year old history, as well as contemporary art creation on Pepper’s ghost with a specific focus on telepresence. Telepresence, a concept that infused academic debate since 1980, discusses the topic of remote communication, perceived presence transmitted through networked environments. This discourse of telepresence revealed shortcomings in current analytical frameworks. This thesis presents a new model for presence in the context of my research. The standard telepresence model (STM) assumes a direct link between three fundamental components of presence and a measurable impact on the audience. Its three pillars are conceptualised as presence co-factors immersion, interactivity and realism, presented individually in the framework of my practice. My research is firmly rooted in the field of media art and considers the effect of presence in the context of Pepper’s ghost. This Victorian parlour trick serves as an interface, an intermediary for the discussion of live streaming experiences. Three case studies present pillars of the standard model, seeking answers to elemental questions of presence research. The hypothesis assumes a positive relationship between presence and its three co-factors. All case studies were developed as media art pieces in the context of Pepper’s ghost. As exemplifiers, they illustrate the concept of presence in respect of my own creative practice. KIMA, a real-time sound representation experience, proposes a form of telepresence that relies exclusively on immersive sound as a medium. Immersion as co-factor of presence is analysed and explored creatively on the Pepper’s ghost canvas. Transmission, the second case study, investigates the effect of physical interaction on presence experiences. An experiment helps to draw inferences in a mixed method approach. The third case study, Aura, discusses variations of realism as presence co factor in the specific context of Pepper’s ghost. The practical example is accompanied by an in-depth meta-analysis of realism factors, specifically focusing on the intricacies of Pepper’s ghost creative production processes. Together, these three case studies help to shed light on new strategies to improve production methods with possible impact on presence in Pepper’s ghost related virtual environments – and beyond

    VibEmoji: Exploring User-authoring Multi-modal Emoticons in Social Communication

    Emoticons are indispensable in online communications. With users’ growing needs for more customized and expressive emoticons, recent messaging applications begin to support (limited) multi-modal emoticons:, enhancing emoticons with animations or vibrotactile feedback. However, little empirical knowledge has been accumulated concerning how people create, share and experience multi-modal emoticons in everyday communication, and how to better support them through design. To tackle this, we developed VibEmoji, a user-authoring multi-modal emoticon interface for mobile messaging. Extending existing designs, VibEmoji grants users greater flexibility to combine various emoticons, vibrations, and animations on-the-fly, and offers non-aggressive recommendations based on these components’ emotional relevance. Using VibEmoji as a probe, we conducted a four-week field study with 20 participants, to gain new understandings from in-the-wild usage and experience, and extract implications for design. We thereby contribute to both a novel system and various insights for supporting users’ creation and communication of multi-modal emoticons

    Paradoxes of interactivity: perspectives for media theory, human-computer interaction, and artistic investigations

    Get PDF
    Current findings from anthropology, genetics, prehistory, cognitive and neuroscience indicate that human nature is grounded in a co-evolution of tool use, symbolic communication, social interaction and cultural transmission. Digital information technology has recently entered as a new tool in this co-evolution, and will probably have the strongest impact on shaping the human mind in the near future. A common effort from the humanities, the sciences, art and technology is necessary to understand this ongoing co- evolutionary process. Interactivity is a key for understanding the new relationships formed by humans with social robots as well as interactive environments and wearables underlying this process. Of special importance for understanding interactivity are human-computer and human-robot interaction, as well as media theory and New Media Art. "Paradoxes of Interactivity" brings together reflections on "interactivity" from different theoretical perspectives, the interplay of science and art, and recent technological developments for artistic applications, especially in the realm of sound
