Thinking beyond the Cure : a constructive design research investigation into the patient experience of radiotherapy

Mullaney, Tara January 2016 (has links)
This constructive design research dissertation aims to understand how design can be used as part of a composite research approach to generate knowledge about how complex phenomena are composed through their interactions and relationships with various actors, both human and non-human. It has done this by investigating a single phenomenon, the patient experience of radiotherapy. Through the purposeful selection and application of methods, theories, and existing research from design, nursing, and STS, this thesis utilizes a mixed-method approach comprised of qualitative, quantitative methods, and design experimentation, across multiple research sites and patient populations, in three research projects – PERT, DUMBO, and POIS – to generate rich and layered knowledge of the patient experience. Experience prototypes are used to challenge, through intervention or provocation, the relationships between the various radiotherapy actors identified through the empirical methods. Together, the research generated in PERT, DUMBO, and POIS construct a map of the networked, interdependent actors which shape the patient’s emotional experience of radiotherapy: the staff, technology, information, environment, and institutions. It also calls attention to the problematic relationship between radiotherapy patients and the technologies used to treat them, which can lead to anxiety, worry, and fear. This thesis offers contributions related to both improving patient experience and designing for complex social issues. First, this research suggests that individuals, other than primary users, need to be acknowledged in the design of medical technologies. It proposes calling attention to patients by naming them as interactors in their relationships with the aforementioned technologies, removing them from the role of implicated actor. Second, this thesis problematizes treating the actors within a network as independent entities, which medical research and user-centered design often does, and calls for a new type of design practice which attends to these networked relationships. Third, this thesis suggests two ways in which design research practice should be shifted methodologically if it wants to engage with and design for complex social issues like patient experience; widening the researcher’s perspective on the issue through the use of a composite methodology, and having the researcher maintain this scope by remaining closely connected to their research context. The implications of this work concern how design research, design education, and design practice might shift their approaches to fully acknowledge and attend to the complexity of systems like healthcare.

Visible Light Communication as a material for design / Kommunikation med synligt ljus som ett design material

Windlin, Charles January 2016 (has links)
Visible light communication (VLC) is a novel complement to Radio Frequency Communication (RFC) and has many applications in wireless communication, indoor positioning and where RFC is not applicable. The problem is that the technology is black-boxed and therefore hard to apply in today’s design process. For designers to be able to use VLC in their creative process, this study uses the Inspirational Bits approach to expose the materiality of VLC by asking the question: How can we design artefacts that allow designers to engage in a conversation with Visible Light Communication as a material? Through Constructive Design Research, the technology was studied in iterations by building prototypes and reflecting on them. The prototypes are evaluated in two design workshops through observation and gathered feedback from 11 participants. As a result, seven artefacts were constructed to expose seven potential material properties of VLC. The observations and collected feedback show also that the artefacts help designers to gain tacit knowledge about VLC. The artefacts use the Arduino platform and standard electrical components. A by-product of this study is the "lumoino" toolkit for tinkering and prototyping with VLC. Eventually, strengths and weaknesses are discussed, and future work sections show the potential extensions of the artefacts and expansions of the toolkit. / ”Kommunikation med synligt ljus” (VLC) som ett design material är ett komplement till ”radio frekvens kommunikation” och har många applikationer inom trådlös kommunikation, Inomhuspositionering, och situationer där RFC inte är applicerbart. Problematiken med teknologi är att den ofta inte är synlig, och därför är svår att inkludera i dagens design processer. För att designers ska kunna använda sig av VLC i deras kreativa process, utgår denna studie från ”Inspirational Bits” förhållningsätt till design, och ämnar utforska följande frågeställning: Hur kan vi designa artefakter som tillåter designers att engagera sig i en konversation med ”kommunikation med synligt ljus” (VLC) som ett design material? Genom ”konstruktiv designforskning”, studerades prototyper av teknologin följt av analys. Processen upprepades med ett flertal modeller. Prototyperna utvärderades i två design-workshops, genom observation av och respons från 11 deltagare. Som resultat, byggdes sju stycken artefakter för att belysa sju stycken potentiella materiella egenskaper av VLC. Observationerna och den samlade responsen visade också att artefakterna hjälpte designers att få taktil kunskap om VLC. Artefakterna baserades på ”the Arduino Platform” och elektriska standard komponenter. En biprodukt av denna studie är ”the lumoino toolkit for tinkering and prototyping with VLC”. Eventuella styrkor och svagheter diskuteras och stycket framtida arbete visar potentiella utvecklingar och expantioner av ”the lumoino toolkit”.

Arrangement Design Studies : the introduction of the digital wall in domestic environments / Designstudier av införandet av den digitala väggen i hemmiljöer

Abdipour, Morteza January 2021 (has links)
This research focuses on the emergence of 'digital walls' that can project images onto almost all or even the entirety of interior (and perhaps exterior) walls, and what implications this might have for how we arrange our rooms. It demonstrates the arrangement, i.e., the way that domestic products are arranged physically, of rooms changes in the domestic environment in a complex scenario when using large screens. Due to the fast-growing demand for large screens, this product could potentially be available to be used by people in their home environments; however, it does not yet exist in reality at this scale. Constructing large screens can be carried out using different production methods. Here, this concept is called the digital wall, a very thin wall-sized interactive screen. The characteristics of the digital wall will vary to be able to create different scenarios. One such scenario is a space in the home where the surface of the wall is covered with screens, which allows multiple possibilities to experience and interact with digital content.  In this research, the social gathering space of homes, nowadays called the living room, is considered as a highly relevant space for installing the digital wall. In this space, the conceptual framework outlines the basic elements of the research and demonstrates the relationships between people’s interactions with the digital wall and domestic products in the domestic environment. I show two examples from design history to understand how arrangement changes impact the home environment: the transformation of the parlor to the living room, and entry of the television into the living room. These two examples are focused on the place in the home where people gather for socializing. The discussion of these examples led to the elaboration of the relationships between the elements in the conceptual framework. I explored relevant design research methodologies to bring this future scenario into the present to understand the relationships between people and the digital wall. I applied research through design and the constructive design research approaches to frame the design research methodology. In this thesis, I set up seven series of design studies in two cluster groups: Supportive studies and Main studies. All of the design studies were conducted in the Design Research Lab, the actual space for carrying out the design experiments, prototyping the digital wall, and the setting of the experiments for user participation. The Lab was fully equipped with relevant technology and allowed me to use multiple methods to collect data while people were experiencing the design study sessions. The Lab was useful as a platform to understand user experiences, barriers for interactions as well as people's experiences in a simulated space of a domestic environment.  The main contribution of this research is to understand the forms of arrangement changes when people use the digital wall in homes. The research demonstrates two significant implications that are seen in two forms of arrangements: tangible arrangement and imperceptible arrangement. These findings are useful for both designers and users of the elements of domestic contexts and the relations that can be shaped by the presence of a digital wall in home environments. This understanding may provide design guidelines in future scenarios in which the digital wall is used in homes. The findings are also beneficial for designing the domestic environment, improving the arrangement of space, and raising the requirements for designing domestic products.

A user-centered design study on interactive CVs in the IT consultant industry from the consultant seller and consultant buyer perspective / En användarcentrerad designstudie om interaktiva CV:n inom IT-konsultbranschen ur konsultsäljarens och konsultköparens perspektiv

Gustavsson, Anna January 2022 (has links)
The recruiter’s first impression of a candidate is often formed through the candidate’s CV, and the CV plays a vital role in recruitment processes for convincing the recruiter to proceed with an applicant to a first interview. Thus, it needs to catch the recruiter’s attention and show whether the candidate is an ideal match for what the recruiter is looking for. With the aim to explore web-based CVs with interactive elements and examine users’ habits and requirements in IT consultant recruitment processes, this study asks the question: How can the user experience of an interactive CV page be improved to help facilitate the recruitment process of consultants? By applying an iterative, user-centered design approach, utilizing the Constructive Design Research framework, the study results in a prototype and proposes design suggestions drawing on knowledge generated from the prototype. Further, three characteristics essential to improve the user experience and help facilitate the recruitment process of consultants are suggested. / En rekryterareres första intryck av en kandidat bildas ofta genom kandidatens CV. Vidare spelar CV:t en avgörande roll i rekryteringsprocesser för att övertyga rekryteraren att gå vidare med en kandidat till en första intervju. Detta innebär att ett CV måste fånga en rekryterares uppmärksamhet och visa huruvida kandidaten är en idealistisk match för det rekryteraren letar efter. I syfte att utforska webbaserade CV:n med interaktiva element och undersöka användares vanor och krav i rekryteringsprocesser för IT-konsulter, ställer denna studie forskningsfrågan: Hur kan användarupplevelsen av en interaktiv CV-sida förbättras för att underlätta i rekryteringsprocessen av konsulter? Genom att tillämpa en iterativ användarcentrerad designstrategi där konstruktiv designforskning tillämpas, resulterar studien i en prototyp och föreslår dessutom designförslag utifrån kunskap genererad från prototypen. Vidare föreslås av studien tre attribut som anses vara väsentliga för att förbättra användarupplevelsen och hjälpa till att underlätta rekryteringsprocessen av konsulter.

Estudio hidrotérmico de cubiertas ajardinadas. Análisis y recomendaciones de diseño para una mayor eficiencia energética

Garcia Borràs, Júlia 20 July 2023 (has links)
[ES] Las cubiertas ajardinadas forman parte de las soluciones, diseños y sistemas constructivos de la arquitectura sostenible. El equilibrio entre las dimensiones ambiental, social y económica en aras de conseguir el máximo bienestar y desarrollo de nuestras sociedades influye en cómo se construye. La rehabilitación energética de un parque de viviendas cada día más envejecido y deteriorado permite reducir el consumo energético desde dos puntos de vista: aprovechando recursos ya existentes, al ampliar la vida útil de edificios todavía estructuralmente funcionales, pero en una condiciones térmicas, de salubridad o equipamiento deficientes; y reduciendo el consumo energético de estos edificios, con los beneficios que ello supone para el medio ambiente, la economía y el bienestar social de sus usuarios y del entorno. En la presente tesis doctoral se profundiza en el comportamiento energético y térmico de las cubiertas ajardinadas en rehabilitación, estructurándose en dos apartados que abordan el estudio de la reducción del consumo energético y las consideraciones constructivas para una correcta ejecución de estos sistemas ajardinados. En el primer apartado se analiza la distribución de temperaturas y humedades relativas en las diferentes capas de modelos reales a escala de cubiertas ajardinadas. Las conclusiones extraídas de estos datos tomados mediante data-loggers, para la ciudad de València, se comparan con el funcionamiento de los mismos sistemas constructivos de cubierta, diseñados y simulados a través de modelos informáticos. Este proceso permite estudiar no solo el comportamiento térmico de la cubierta, sino también su funcionamiento energético y el posible ahorro a conseguir en diferentes hipótesis de rehabilitación de una vivienda, considerando también la posible intervención sobre otros elementos de la envolvente térmica. El mecanismo de evapotranspiración presenta un papel importante en la disipación de calor de las cubiertas ajardinadas, por lo que se profundiza en su estudio para el caso de cubiertas autosuficientes, es decir, sin aporte de agua de riego. Este sistema de cubierta ajardinada pretende responder a la problemática escasez de agua a la que se enfrenta parte del territorio español, especialmente en la costa mediterránea en la que se ubica la ciudad de València. También se profundiza en la comprensión sobre qué variables climáticas, de entre temperatura ambiente, radiación solar y precipitaciones, son más influyentes en este proceso. La relación de la evapotranspiración con el agua almacenada, en las capas de la cubierta dispuestas a tal fin, queda patente, reduciéndose este proceso a menor disponibilidad de agua, especialmente en climas como el mediterráneo, con escasas precipitaciones y elevada temperatura ambiental y radiación solar. Todas las reflexiones obtenidas permiten confirmar las limitaciones en las pérdidas de calor por evapotranspiración derivadas de la escasez de agua, lo que conlleva la necesidad de buscar posibles soluciones que mejoren su comportamiento energético. Cada una de las situaciones estudiadas, conocidas y planteadas sus debilidades y fortalezas, permite concluir cuál es el mejor sistema constructivo de cubierta ajardinada para el caso de rehabilitación, principal aportación de este trabajo. En el segundo y último apartado, se realiza el estudio constructivo de una rehabilitación mediante el sistema de cubierta ajardinada escogido previamente. Esto permite detectar y conocer los problemas y soluciones que afrontar para conseguir una correcta ejecución, la cual supondrá mejorar la accesibilidad, mantenimiento, sostenibilidad y vida útil del sistema ajardinado de cubierta. Comprender el comportamiento energético de las cubiertas ajardinadas, así como las particularidades de instalación y construcción, permite ampliar su difusión, aplicación y los beneficios ambientales, sociales y económicos que de su uso se derivan. / [CA] Les cobertes enjardinades formen part de les solucions, dissenys i sistemes constructius de l'arquitectura sostenible. L'equilibri entre les dimensions ambiental, social i econòmica a fi d'aconseguir el màxim benestar i desenvolupament de les nostres societats influeix en com es construeix. La rehabilitació energètica d'un parc d'habitatges cada dia més envellit i deteriorat permet reduir el consum energètic des de dos punts de vista: aprofitant recursos ja existents, en ampliar la vida útil d'edificis encara estructuralment funcionals, però en una condicions tèrmiques, de salubritat o equipament deficients; i reduint el consum energètic d'aquests edificis, amb els beneficis que això suposa per al medi ambient, l'economia i el benestar social dels seus usuaris i de l'entorn. En la present tesi doctoral s'aprofundeix en el comportament energètic i tèrmic de les cobertes enjardinades en rehabilitació, estructurant-se en dos apartats que aborden l'estudi de la reducció del consum energètic i les consideracions constructives per a una correcta execució d'aquests sistemes enjardinats. En el primer apartat s'analitza la distribució de temperatures i humitats relatives en les diferents capes de models reals a escala de cobertes enjardinades. Les conclusions extretes d'aquestes dades preses mitjançant data-loggers, per a la ciutat de València, es comparen amb el funcionament dels mateixos sistemes constructius de coberta, dissenyats i simulats a través de models informàtics. Aquest procés permet estudiar no sols el comportament tèrmic de la coberta, sinó també el seu funcionament energètic i el possible estalvi a aconseguir en diferents hipòtesis de rehabilitació d'un habitatge, considerant també la possible intervenció sobre altres elements de l'envolupant tèrmica. El mecanisme d'evapotranspiració presenta un paper important en la dissipació de calor de les cobertes enjardinades, per la qual cosa s'aprofundeix en el seu estudi per al cas de cobertes autosuficients, és a dir, sense aportació d'aigua de reg. Aquest sistema de coberta enjardinada pretén respondre a la problemàtica escassetat d'aigua a la qual s'enfronta part del territori espanyol, especialment en la costa mediterrània en la qual se situa la ciutat de València. També s'aprofundeix en la comprensió sobre quines variables climàtiques, d'entre temperatura ambient, radiació solar i precipitacions, són més influents en aquest procés. La relació de l'evapotranspiració amb l'aigua emmagatzemada, en les capes de la coberta disposades a tal fi, queda patent, reduint-se aquest procés a menor disponibilitat d'aigua, especialment en climes com el mediterrani, amb escasses precipitacions i elevada temperatura ambiental i radiació solar. Totes les reflexions obtingudes permeten confirmar les limitacions en les pèrdues de calor per evapotranspiració derivades de l'escassetat d'aigua, la qual cosa comporta la necessitat de buscar possibles solucions que milloren el seu comportament energètic. Cadascuna de les situacions estudiades, conegudes i plantejades les seues febleses i fortaleses, permet concloure quin és el millor sistema constructiu de coberta enjardinada per al cas de rehabilitació, principal aportació d'aquest treball. En el segon i últim apartat, es realitza l'estudi constructiu d'una rehabilitació mitjançant el sistema de coberta enjardinada triat prèviament. Això permet detectar i conéixer els problemes i solucions que afrontar per a aconseguir una correcta execució, la qual suposarà millorar l'accessibilitat, manteniment, sostenibilitat i vida útil del sistema enjardinat de coberta. Comprendre el comportament energètic de les cobertes enjardinades, així com les particularitats d'instal·lació i construcció, permet ampliar la seua difusió, aplicació i els beneficis ambientals, socials i econòmics que del seu ús es deriven. / [EN] Green roofs are part of the solutions, designs and construction systems of sustainable architecture. The balance between the environmental, social and economic dimensions in order to achieve the maximum well-being and development of our societies influences how to build. The energy renovation of an increasingly aged and deteriorated housing stock allows energy consumption to be reduced from two points of view: taking advantage of already existing resources, by extending the useful life of buildings that are still structurally functional, but in thermal, health or equipment poor conditions; and reducing the energy consumption of these buildings, with the benefits that this implies for the environment, the economy and the social well-being of its users and the surroundings. This thesis delves into the energy and thermal behaviour of green roofs under renovation, structured into two sections that address the study of energy consumption reduction and construction considerations for proper execution of these vegetated systems. The first section analyses the distribution of temperatures and relative humidity in the different layers of real-scale models of green roofs. The conclusions drawn from these data taken by data-loggers, for the city of València, are compared with the running of the same roof construction systems, designed and simulated through computer models. This process makes it possible to study not only the thermal behaviour of the roof, but also its energy performance and the possible savings to be achieved in different housing renovation scenarios, also considering the possible intervention on other elements of the thermal envelope. The evapotranspiration mechanism plays an important role in the heat dissipation of green roofs, so its study is deepened in the case of self-sustaining roofs, that is, without irrigation water supply. This green roof system aims to respond to the problematic water shortage that part of the Spanish territory is facing, especially on the Mediterranean coast where the city of València is located. It also deepens the understanding of which climatic variables, among outdoor temperature, solar radiation and precipitation, are most influential in this process. The relationship of evapotranspiration with stored water, in the roof layers arranged for this purpose, is evident, reducing this process to less water availability, especially in climates such as the Mediterranean, with low precipitation and high outdoor temperature and solar radiation. All the reflections obtained make it possible to confirm the limitations in heat losses due to evapotranspiration derived from water scarcity, which entails the need to look for possible solutions that improve their energetic behaviour. Each of the situations studied, known and raised their weaknesses and strengths, allows us to conclude which is the best green roof construction system for the case of renovation, the main contribution of this work. In the second and last section, the constructive study of a renovation is carried out using the previously chosen green roof system. This makes it possible to detect and learn about the problems and solutions to be faced in order to achieve correct execution, which will mean improving the accessibility, maintenance, sustainability and useful life of the green roof system. Understanding the energy behaviour of green roofs, as well as the particularities of installation and construction, allows to expand its diffusion, application and the environmental, social and economic benefits derived from its use. / Garcia Borràs, J.
