    Today, designers obtain more central roles in product and service development (Perks, Cooper, & Jones, 2005). They have to deal with increasingly complicated problems, like integrating the needs of various stakeholders while taking care about social, ethical and ecological consequences of their designs. To deal with this demanding design situation, they need to apply new methods to organize the available information and to negotiate the stakeholder’s perspectives. This paper describes how systems analysis supports the design process in a complex environment. In a case study, we demonstrate how this method enables designers to describe user requirements for complex design environments while considering the perspectives of various stakeholders. We present a design research project applying cybernetic systems analysis using the software ''System-Tools'' (Vester, 2002). Results from the analysis were taken to inform the design of an electronic patient record (EPR), considering the particularities of the German health care system. Based on the analysis, we developed a set of requirements for every stakeholder group, detailing the patients' perspective with persona descriptions. We then picked a main persona as reference for the EPR design. We describe the resulting design sketch and discuss the value of cybernetic systems analysis as a tool to deal with complex social environments. The result shows how the method helps designers to structure and organize information about the context and identify fruitful intervention opportunities for design.

    The concentration is on “3D space utilization” as the concept and infrastructure of designing of a wearable in ambient parameters monitoring. This strategy is implemented according to “multi-layer” approach. In this approach, each group of parameters from the same category is monitored by a modular physical layer enriched with the respected sensors. Depending on the number of parameters and layers, each physical layer is located on top of another. The intention is to implement a device for “everyone in everywhere for everything”

    Wearable devices for health remote monitor system

    It is feasible to see how communication and information technology have advanced at a rapid pace in today’s world. The introduction and emergence of wearable technology is one aspect that contributes to this advancement and has the potential to be an innovative solution to healthcare challenges, since it may be used for illness prevention and maintenance, such as physical monitoring, as well as patient management. To address some of the healthcare challenges, this research thesis provides a research methodology, research questions, and hypotheses for constructing an health remote monitoring system with alerts and continuous monitoring employing wearable devices capable of collecting biometric data on human health. The concept was then proven by the development of a prototype using wearable devices connected to a microcontroller, which transmits its data via MQTT Protocol to a Node-RED powered dashboard that handles health metrics monitoring and where all monitoring performed, and alarms generated can be viewed in real-time. All this data is delivered to a MongoDB database for further analysis and visualization. To demonstrate the effectiveness and capabilities of this prototype, it was used in the real world and the results were acquired from two distinct users. The results were very favorable and conclusive, demonstrating that the created prototype was satisfactory in providing data to support the developed hypotheses and research questions.É possível observar como as tecnologias de comunicação e informação avançaram a um ritmo bastante acelerado nos dias de hoje. A introdução e aparecimento da tecnologia ”wearable” representa um aspeto que contribui para este progresso e tem o potencial de ser uma solução inovadora para os desafios dos cuidados de saúde, uma vez que pode ser utilizada para a prevenção e manutenção de doenças, tais como a monitorização física, bem como para a gestão de pacientes. Para abordar alguns dos desafios dos cuidados de saúde, esta tese de investigação propõe uma metodologia de investigação, questões de investigação, e hipóteses para o desenvolvimento de um sistema inteligente de monitorização da saúde com alertas e monitorização contínua utilizando wearable devices capazes de recolher dados biométricos de seres humanos. O conceito foi então provado pelo desenvolvimento de um protótipo utilizando wearable devices conectados a um microcontrolador, que transmite os seus dados através do Protocolo MQTT a um painel de instrumentos alimentado por o Node-RED que lida com a monitorização de métricas de saúde e onde toda a monitorização executada, e os alarmes gerados, podem ser visualizados em tempo real e depois entregues numa base de dados MongoDB para posterior análise e visualização. Para demonstrar a eficácia deste protótipo, este foi implementado no mundo real onde foram adquiridos vários resultados através da utilização de dois utilizadores distintos. Os resultados foram bastante favoráveis e conclusivos, demonstrando que o protótipo criado foi satisfatório no fornecimento de dados para apoiar as hipóteses e questões de investigação desenvolvidas

    How to Make Fabrics Talk Environment: The Scatol8 per la Sostenibilità Way

    The mission of Scatol8 per la Sostenibilità srl (in English Scatol8 for Sustainability) is the realization of products and services to communicate the theme of sustainable development. The economic viability of the entrepreneurial initiative is ensured by three lines of activity: (1) the realization of personalized management systems, (2) carrying out environmental education activities, and (3) design and manufacture of products. Scatol8’s products are unique design objects—therefore exclusive—crafted with materials and techniques derived from scientific research. Osmosis between new researches in the fields of business management, chemistry, environment, and the Scatol8 company leads to the manufacture of products that incorporate recent innovations and transfer the knowledge content to those who can afford them, meaning those who have culture enough to understand and appreciate them. It has been said: luxury is experiential. This is the concept we aim for with our products. The following chapter describes the qualities of some sustainable luxury products and deepens the ways of thinking, designing, and making a line of garments. These garments incorporate electronic devices with natural fabrics: cotton, hemp, and eco-leather. This is an example of upcycling as a result of technological innovation, which is then analyzed by the design thinking

    We designed a low-cost wrist-worn prototype for simultaneously measuring environmental, behavioral, and physiological domains of influencing factors in healthcare. Our prototype continuously monitors ambient elements (sound level, toxic gases, ultraviolet radiation, air pressure, temperature, and humidity), personal activity (motion tracking and body positioning using gyroscope, magnetometer, and accelerometer), and vital signs (skin temperature and heart rate). An innovative three-dimensional hardware, based on the multi-physical-layer approach is introduced. Using board-to-board connectors, several physical hardware layers are stacked on top of each other. All of these layers consist of integrated and/or add-on sensors to measure certain domain (environmental, behavioral, or physiological). The prototype includes centralized data processing, transmission, and visualization. Bi-directional communication is based on Bluetooth Low Energy (BLE) and can connect to smartphones as well as smart cars and smart homes for data analytic and adverse-event alerts. This study aims to develop a prototype for simultaneous monitoring of the all three areas for monitoring of workplaces and chronic obstructive pulmonary disease (COPD) patients with a concentration on technical development and validation rather than clinical investigation. We have implemented 6 prototypes which have been tested by 5 volunteers. We have asked the subjects to test the prototype in a daily routine in both indoor (workplaces and laboratories) and outdoor. We have not imposed any specific conditions for the tests. All presented data in this work are from the same prototype. Eleven sensors measure fifteen parameters from three domains. The prototype delivers the resolutions of 0.1 part per million (PPM) for air quality parameters, 1 dB, 1 index, and 1 °C for sound pressure level, UV, and skin temperature, respectively. The battery operates for 12.5 h under the maximum sampling rates of sensors without recharging. The final expense does not exceed 133€. We validated all layers and tested the entire device with a 75 min recording. The results show the appropriate functionalities of the prototype for further development and investigations
