Wearable Technology as a Tool to Motivate Health Behaviour: A Case Study

According to the Scientific Committee on Occupational Exposure Limits, work-related exposures are estimated to account for about 15% of all adult respiratory diseases. Today, the use of personal protective equipment (PPE) is the only way for workers to prevent disease. Nevertheless, its use is highly sparse. Currently, products and systems embedded with wearable technologies are able to protect, motivate and educate users. The authors then suggested the development of a novel wearable system following the beliefs that wearable technology can be persuasive and elicit a conscious behaviour towards the use of the PPEs by consequently improving their health condition. The authors here describe the result of a Transnational Research Project named “P_O_D Plurisensorial Device to prevent Occupational Disease.” The chapter describes the findings achieved so far, the research phase and the new wearable system conceived as a possible example of how to use wearable technology as a useful tool to influence behavioural change

Computerized Identification of Mental State for Mental Health Care

Introduction Sebastian, a 30-year-old man, was just diagnosed with depression and is undergoing cognitive-behavioral therapy (CBT) sessions on a weekly basis. As he goes about his daily routine, he wears a gadget that measures his physiological activity. His therapist enters his physiological data for the week into a computer software at the start of each CBT session. The computer compiles Sebastian's levels of happy and negative affect and pinpoints the times when these reactions peaked. The therapist utilizes this information to track Sebastian's development and dynamically customize the therapy, for as by asking Sebastian to recollect experiences that correlate to some of the emotion peaks

Healthcare in the Smart Home: A Study of Past, Present and Future

Open Access journalUbiquitous or Pervasive Computing is an increasingly used term throughout the technology industry and is beginning to enter the consumer electronics space in its most recent form under the umbrella term: “Internet of Things”. One area of focus is in augmenting the home with intelligent, networked sensors and computers to create a Smart Home which opens a host of possibilities for the role of tomorrow’s dwelling. As the world’s population continues to live longer and consequently experience more medical-related ailments, at the same time institutional healthcare is struggling to cope, the role of the Smart Home becomes paramount to monitoring a dweller’s health and providing any necessary intervention. This study looks at the history of Smart Home Healthcare, current research areas, and potential areas of future investigation. Unique categorisations are presented in Activities of Daily Living (ADL) and Personal Sensors, and a thorough look at the application of Smart Home Healthcare is presented. Technology can augment traditional methods of healthcare delivery and in some cases completely replace it. Costs can be reduced and medical adherence can be increased, all of which contribute to a more sustainable and effective model of care

Towards disappearing user interfaces for ubiquitous computing: human enhancement from sixth sense to super senses

The enhancement of human senses electronically is possible when pervasive computers interact unnoticeably with humans in Ubiquitous Computing. The design of computer user interfaces towards “disappearing” forces the interaction with humans using a content rather than a menu driven approach, thus the emerging requirement for huge number of non-technical users interfacing intuitively with billions of computers in the Internet of Things is met. Learning to use particular applications in Ubiquitous Computing is either too slow or sometimes impossible so the design of user interfaces must be naturally enough to facilitate intuitive human behaviours. Although humans from different racial, cultural and ethnic backgrounds own the same physiological sensory system, the perception to the same stimuli outside the human bodies can be different. A novel taxonomy for Disappearing User Interfaces (DUIs) to stimulate human senses and to capture human responses is proposed. Furthermore, applications of DUIs are reviewed. DUIs with sensor and data fusion to simulate the Sixth Sense is explored. Enhancement of human senses through DUIs and Context Awareness is discussed as the groundwork enabling smarter wearable devices for interfacing with human emotional memories

In-Material Processing of High Bandwidth Sensor Measurements Using Modular Neural Networks

Robotic materials are a novel class of materials that tightly integrate sensing, computing, and actuation into an engineered material or composite to allow the behavior of the material to be defined algorithmically. Robotic materials are constructed using an embedded network of computing nodes based on small, inexpensive microcontrollers. Examples of such materials include morphable airfoils which change shape in response to flight conditions or mission parameters, robotic skins with rich tactile sensing capabilities that recognize texture or touch gestures, clothing with tightly integrated sensing to assist with or augment the wearer's perception of the environment, or materials with dynamic camouflage capabilities.In this thesis, I develop a framework for in-material processing which tightly couples modularized deep neural networks and high-bandwidth sensors using a network of embedded, material-scale components. This framework enables materials to learn multiple desired responses to stimuli, avoiding the need for accurate modeling of the dynamics of the material and stimuli. I utilize a modular neural network design consisting of convolutional (CNN) and long short-term memory (LSTM) layers implemented in each node in the material as a computational approach for robotic materials. This network architecture allows for nodes in the material to process local sensor values, maintain local state information, and communicate with nodes in a local neighborhood in the materials. A multiobjective optimization approach is employed to automatically design the neural network architectures which maximizes the performance of the network while ensuring hardware budgets, such as memory requirements, are maintained. A communication network design is also developed to allow network modules to learn a communication protocol that limits communication to a desired rate, ensuring in-network bandwidth constraints are maintained.I demonstrate the suitability of this computational model for robotic materials using examples in several domains. An RF-based e-textile gesture input device capable of distinguishing between user control gestures is used to control arbitrary external devices. A tire with embedded piezoelectric sensing capabilites for use in high-performance autonomous vehicles performs state-of-the-art identification of terrains driven on. Two robotic skins are presented---one which is capable of detecting and localizing contact, and identifying the texture of the contacting objects; and a second which assists with avoiding collisions with obstacles and identifies affective touch gestures performed by a human collaborator. Finally, a distributed approach to human activity recognition is presented whose activity identification performance is comparable to a centralized approach, but can be implemented on hardware designed for wearable applications, as opposed to a GPU-enabled device. The examples shown demonstrate that robotic materials can perform significant in-material processing; are loosely coupled from a host system, communicating a minimal number of low-bandwidth events to the host; and can exhibit multifunctional behavior that is analyzed for safety or performance considerations

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

Affective Computing for Emotion Detection using Vision and Wearable Sensors

The research explores the opportunities, challenges, limitations, and presents advancements in computing that relates to, arises from, or deliberately influences emotions (Picard, 1997). The field is referred to as Affective Computing (AC) and is expected to play a major role in the engineering and development of computationally and cognitively intelligent systems, processors and applications in the future. Today the field of AC is bolstered by the emergence of multiple sources of affective data and is fuelled on by developments under various Internet of Things (IoTs) projects and the fusion potential of multiple sensory affective data streams. The core focus of this thesis involves investigation into whether the sensitivity and specificity (predictive performance) of AC, based on the fusion of multi-sensor data streams, is fit for purpose? Can such AC powered technologies and techniques truly deliver increasingly accurate emotion predictions of subjects in the real world? The thesis begins by presenting a number of research justifications and AC research questions that are used to formulate the original thesis hypothesis and thesis objectives. As part of the research conducted, a detailed state of the art investigations explored many aspects of AC from both a scientific and technological perspective. The complexity of AC as a multi-sensor, multi-modality, data fusion problem unfolded during the state of the art research and this ultimately led to novel thinking and origination in the form of the creation of an AC conceptualised architecture that will act as a practical and theoretical foundation for the engineering of future AC platforms and solutions. The AC conceptual architecture developed as a result of this research, was applied to the engineering of a series of software artifacts that were combined to create a prototypical AC multi-sensor platform known as the Emotion Fusion Server (EFS) to be used in the thesis hypothesis AC experimentation phases of the research. The thesis research used the EFS platform to conduct a detailed series of AC experiments to investigate if the fusion of multiple sensory sources of affective data from sensory devices can significantly increase the accuracy of emotion prediction by computationally intelligent means. The research involved conducting numerous controlled experiments along with the statistical analysis of the performance of sensors for the purposes of AC, the findings of which serve to assess the feasibility of AC in various domains and points to future directions for the AC field. The AC experiments data investigations conducted in relation to the thesis hypothesis used applied statistical methods and techniques, and the results, analytics and evaluations are presented throughout the two thesis research volumes. The thesis concludes by providing a detailed set of formal findings, conclusions and decisions in relation to the overarching research hypothesis on the sensitivity and specificity of the fusion of vision and wearables sensor modalities and offers foresights and guidance into the many problems, challenges and projections for the AC field into the future

A Sensing Platform to Monitor Sleep Efficiency

Sleep plays a fundamental role in the human life. Sleep research is mainly focused on the understanding of the sleep patterns, stages and duration. An accurate sleep monitoring can detect early signs of sleep deprivation and insomnia consequentially implementing mechanisms for preventing and overcoming these problems. Recently, sleep monitoring has been achieved using wearable technologies, able to analyse also the body movements, but old people can encounter some difficulties in using and maintaining these devices. In this paper, we propose an unobtrusive sensing platform able to analyze body movements, infer sleep duration and awakenings occurred along the night, and evaluating the sleep efficiency index. To prove the feasibility of the suggested method we did a pilot trial in which several healthy users have been involved. The sensors were installed within the bed and, on each day, each user was administered with the Groningen Sleep Quality Scale questionnaire to evaluate the user’s perceived sleep quality. Finally, we show potential correlation between a perceived evaluation with an objective index as the sleep efficiency.</p
