Development of Economic Water Usage Sensor and Cyber-Physical Systems Co-Simulation Platform for Home Energy Saving

In this thesis, two Cyber-Physical Systems (CPS) approaches were considered to reduce residential building energy consumption. First, a flow sensor was developed for residential gas and electric storage water heaters. The sensor utilizes unique temperature changes of tank inlet and outlet pipes upon water draw to provide occupant hot water usage. Post processing of measured pipe temperature data was able to detect water draw events. Conservation of energy was applied to heater pipes to determine relative internal water flow rate based on transient temperature measurements. Correlations between calculated flow and actual flow were significant at a 95% confidence level. Using this methodology, a CPS water heater controller can activate existing residential storage water heaters according to occupant hot water demand. The second CPS approach integrated an open-source building simulation tool, EnergyPlus, into a CPS simulation platform developed by the National Institute of Standards and Technology (NIST). The NIST platform utilizes the High Level Architecture (HLA) co-simulation protocol for logical timing control and data communication. By modifying existing EnergyPlus co-simulation capabilities, NIST’s open-source platform was able to execute an uninterrupted simulation between a residential house in EnergyPlus and an externally connected thermostat controller. The developed EnergyPlus wrapper for HLA co-simulation can allow active replacement of traditional real-time data collection for building CPS development. As such, occupant sensors and simple home CPS product can allow greater residential participation in energy saving practices, saving up to 33% on home energy consumption nationally

Virtual Touch: Embodied Experiences of (dis)Embodied Intimacy in Mediatized Performance

In this dissertation, I explore a phenomenon I call virtual touch, in which embodied sensations of touch are felt through non-tactile senses. In the digital age, online interactivity has expanded the ways in which individuals experience connection, intimacy, and touch. Digital media, which have traditionally been thought of as disembodied, nevertheless have the ability to elicit intense feelings of touch. Through analysis of digital and virtual installation art, I examine the ways that non-tactile touch remains rooted in the embodied experience. The works I include in this study create a feeling of virtual touch through a co-functioning of the senses, and through what Brian Massumi terms “the superiority of the analog,” in which all experience is inherently rooted in the body. Grounded in Merleau-Ponty’s theory of the embodied subject, I focus on three broad categories of installation art, each of which creates an affective response of virtual touch through senses of sight and proprioception: telematic performance using video-conferencing technology, digitally reactive animations, and immersive sculptures of light designed to decenter the perceptual and visual senses. Along with works by artists Paul Sermon, Adrien M & Claire B, teamLab, and James Turrell, I include analyses of two research performances I created, Being Present (2016) and (dis)embodied in space (2019), both of which entangled live and mediatized bodies through telematic video technology. Each of the artworks that I include place an emphasis on the embodied experience, engaging bodies in interactions of virtual touch with other bodies, with digitally reactive artworks, and with light and space. Throughout this dissertation, I argue for a rethinking of concepts of touch, intimacy, and connection in the digital age

Constructing living buildings: a review of relevant technologies for a novel application of biohybrid robotics

Biohybrid robotics takes an engineering approach to the expansion and exploitation of biological behaviours for application to automated tasks. Here, we identify the construction of living buildings and infrastructure as a high-potential application domain for biohybrid robotics, and review technological advances relevant to its future development. Construction, civil infrastructure maintenance and building occupancy in the last decades have comprised a major portion of economic production, energy consumption and carbon emissions. Integrating biological organisms into automated construction tasks and permanent building components therefore has high potential for impact. Live materials can provide several advantages over standard synthetic construction materials, including self-repair of damage, increase rather than degradation of structural performance over time, resilience to corrosive environments, support of biodiversity, and mitigation of urban heat islands. Here, we review relevant technologies, which are currently disparate. They span robotics, self-organizing systems, artificial life, construction automation, structural engineering, architecture, bioengineering, biomaterials, and molecular and cellular biology. In these disciplines, developments relevant to biohybrid construction and living buildings are in the early stages, and typically are not exchanged between disciplines. We, therefore, consider this review useful to the future development of biohybrid engineering for this highly interdisciplinary application.publishe

Respite Park: Changing Therapy With Community and Architecture

Architecture can be a driving force of change within communities. Through a new kind of public park with therapeutic experience pavilions based on community interaction and integration, as well as innovative architectural design. This thesis explores the creation of spaces that allow for a further push for a general acceptance of cognitive behavior therapy in culture. Through researching what methods of cognitive behavioral therapy are wildly successful, combining that with research on innovative sensory architectural techniques and interactive art Installations to create perspective altering experiences. In which, for visitors, the physical and emotional distance required for self-reflection is created. The intent is to provide a place where cognitive behavioral therapy can be more easily approached while eliminating a common negative stigma behind seeking help when it is needed

Haptic Media Scenes

The aim of this thesis is to apply new media phenomenological and enactive embodied cognition approaches to explain the role of haptic sensitivity and communication in personal computer environments for productivity. Prior theory has given little attention to the role of haptic senses in influencing cognitive processes, and do not frame the richness of haptic communication in interaction design—as haptic interactivity in HCI has historically tended to be designed and analyzed from a perspective on communication as transmissions, sending and receiving haptic signals. The haptic sense may not only mediate contact confirmation and affirmation, but also rich semiotic and affective messages—yet this is a strong contrast between this inherent ability of haptic perception, and current day support for such haptic communication interfaces. I therefore ask: How do the haptic senses (touch and proprioception) impact our cognitive faculty when mediated through digital and sensor technologies? How may these insights be employed in interface design to facilitate rich haptic communication? To answer these questions, I use theoretical close readings that embrace two research fields, new media phenomenology and enactive embodied cognition. The theoretical discussion is supported by neuroscientific evidence, and tested empirically through case studies centered on digital art. I use these insights to develop the concept of the haptic figura, an analytical tool to frame the communicative qualities of haptic media. The concept gauges rich machine- mediated haptic interactivity and communication in systems with a material solution supporting active haptic perception, and the mediation of semiotic and affective messages that are understood and felt. As such the concept may function as a design tool for developers, but also for media critics evaluating haptic media. The tool is used to frame a discussion on opportunities and shortcomings of haptic interfaces for productivity, differentiating between media systems for the hand and the full body. The significance of this investigation is demonstrating that haptic communication is an underutilized element in personal computer environments for productivity and providing an analytical framework for a more nuanced understanding of haptic communication as enabling the mediation of a range of semiotic and affective messages, beyond notification and confirmation interactivity

Tangible user interfaces : past, present and future directions

In the last two decades, Tangible User Interfaces (TUIs) have emerged as a new interface type that interlinks the digital and physical worlds. Drawing upon users' knowledge and skills of interaction with the real non-digital world, TUIs show a potential to enhance the way in which people interact with and leverage digital information. However, TUI research is still in its infancy and extensive research is required in or- der to fully understand the implications of tangible user interfaces, to develop technologies that further bridge the digital and the physical, and to guide TUI design with empirical knowledge. This paper examines the existing body of work on Tangible User In- terfaces. We start by sketching the history of tangible user interfaces, examining the intellectual origins of this field. We then present TUIs in a broader context, survey application domains, and review frame- works and taxonomies. We also discuss conceptual foundations of TUIs including perspectives from cognitive sciences, phycology, and philoso- phy. Methods and technologies for designing, building, and evaluating TUIs are also addressed. Finally, we discuss the strengths and limita- tions of TUIs and chart directions for future research

The Case for Public Interventions during a Pandemic

Funding Information: This work has been supported by Marie Skłodowska Curie Actions ITN AffecTech (ERC H2020 Project 1059 ID: 722022). Publisher Copyright: © 2022 by the authors.Within the field of movement sensing and sound interaction research, multi-user systems have gradually gained interest as a means to facilitate an expressive non-verbal dialogue. When tied with studies grounded in psychology and choreographic theory, we consider the qualities of interaction that foster an elevated sense of social connectedness, non-contingent to occupying one’s personal space. Upon reflection of the newly adopted social distancing concept, we orchestrate a technological intervention, starting with interpersonal distance and sound at the core of interaction. Materialised as a set of sensory face-masks, a novel wearable system was developed and tested in the context of a live public performance from which we obtain the user’s individual perspectives and correlate this with patterns identified in the recorded data. We identify and discuss traits of the user’s behaviour that were accredited to the system’s influence and construct four fundamental design considerations for physically distanced sound interaction. The study concludes with essential technical reflections, accompanied by an adaptation for a pervasive sensory intervention that is finally deployed in an open public space.publishersversionpublishe

Flora Robotica – Mixed Societies of Symbiotic Robot-Plant Bio-Hybrids

Besides the life-as-it-could-be driver of artificial life research there is also the concept of extending natural life by creating hybrids or mixed societies that are built from both natural and artificial components. In this paper, we motivate and present the research program of the project flora robotica. We present our concepts of control, hardware de-sign, modeling, and human interaction along with preliminary experiments. Our objective is to develop and to investigate closely linked symbiotic relationships between robots and natural plants and to explore the potentials of a plant-robot society able to produce archi-tectural artifacts and living spaces. These robot-plant bio-hybrids create synergies that allow for new functions of plants and robots. They also create novel design opportunities for an architecture that fuses the design and construction phase. The bio-hybrid is an example of mixed societies between ‘hard artificial and ‘wet natural life, which enables an interaction between natural and artificial ecologies. They form an embodied, self-organizing, and distributed cognitive system which is supposed to grow and develop over long periods of time resulting in the creation of meaningful architectural structures. A key idea is to assign equal roles to robots and plants in order to create a highly integrated, symbiotic system. Besides the gain of knowledge, this project has the objective to cre-ate a bio-hybrid system with a defined function and application – growing architectural artifacts

Synthesis Study: Overview of Readily Available Culvert Inspection Technologies

Culverts, conduits that facilitate passage of water beneath roadways and other structures, represent important components of infrastructure systems, helping to drain, direct or divert surface water and prevent the disruption of roadways. Their efficient inspection and maintenance is thus critical to safe operation of Indiana’s transportation infrastructure. Although approximately 25% of culverts associated with INDOT managed roadways are inspected each year, inspectors face many challenges determining the actual condition of culverts, which can vary substantially in material type, form, length, depth of cover, accessibility, and age. This study was therefore performed to understand and synthesize technical culvert inspection alternatives with a focus on identifying and prioritizing readily available solutions. Research revealed that no standard inspection guidelines exist for small culverts, and that inspection practices vary significantly across states. DOT survey results indicate that DOTs primarily rely on visual examination conducted by field personnel, often from the open ends of the culvert, limiting the range of flaws and failure modes that can be identified, and the desired early warning benefits of inspection. While a range of technologies exist to facilitate inspection, most methods apply to only a limited set of culvert materials and operating conditions. This study thus provides a ranked recommendation of readily available culvert inspection solutions, segmented according to their applicability to varying culvert conditions and inspection needs. Techniques involving mobile visual camera systems and multi-sensing modes stand out for their potential to provide insight into the condition of a variety of culvert types at moderate cost
