This thesis describes prototyping in service design through the theoretical lens of situated cognition. The research questions are what a service prototype is, what the benefits of service prototyping are, and how prototypes aid in the process of designing services. Four papers are included. Paper one suggests that service prototyping should be considered from the perspectives of purpose, fidelity, audience, position in the process, technique, representation, validity and author. The second paper compares research about how humans use external representations to think, with reasons for using prototypes in service design and service design techniques. The third paper compares two versions of a service prototyping technique called service walkthrough; showing that walkthroughs with pauses provided both more comments in total and more detailed feedback. The fourth paper also contributes to our understanding of how prototypes aid in designing services, by connecting the surrogate situation with the future situation of service. The paper shows how the formative service evaluation technique (F-SET) uses the theory of planned behaviour to add knowledge to service prototype evaluations about the intention to use a service in the future. Taken together the research provides a deeper understanding of what prototypes are, and their roles in service prototyping. This understanding is further deepened by a discussion about service as a design material, suggesting that from a design perspective, a service consists of service concept, process and system. The service prototype acts as a surrogate for the future situation of service. The thesis describes what the benefits of using surrogates are, and shows how prototypes enhance the ability to gain knowledge about future situations. This leads to an understanding of prototyping as a way of thinking in design. / Den här avhandlingen använder situerad kognition som lins för at beskriva prototypande i tjänstedesign. Genom den här beskrivningen undersöker avhandlingen vad en tjänsteprototyp är, vad fördelarna med att använda prototyper är samt hur prototypande kan användas för att designa tjänster. Fyra artiklar ingår i avhandlingen. Den första artikeln föreslår att tjänsteprototypande ska betraktas från perspektiven syfte, detaljgrad, publik, position i processen, teknik, representation, validitet och författare. Avhandlingens andra artikel jämför forskning om fördelarna med att använda externa representationer för tänkande, med anledningar för att externalisera i tjänstedesign, och tekniker för att göra externa representationer. Den tredje artikeln jämför två variationer av prototypningstekniken tjänstegenomgång, och visar att genomgångar med pauser ger mer kommentarer och mer detaljerad feedback. Den sista artikeln bidrar också till förståelsen av hur prototyper stöder design av tjänster, genom att den kopplar surrogatsituationen och den framtida tjänstesituationen. Artikeln visar hur en teknik kallad formative service evaluation technique använder theory of planned behaviour för att bidra med kunskap om att evaluera tjänster med avseende på intention att använda tjänsten i framtiden. Tillsammans bidrar forskningen till en djupare förståelse av vad prototyper är och deras roller i tjänsteprototypning. Denna förståelse fördjupas ytterligare genom en diskussion av tjänster som designmaterial och avhandlingen föreslår att arbetet att representera och designa tjänster innefattar både design av och för tjänster. Tjänsteprototyper fungerar som surrogat för den framtida tjänstesituationen. Avhandlingen beskriver föredelarna med att använda surrogat och visar hur prototyper stödjer möjligheten att skapa kunskap om framtida tjänstesituationer. Detta leder till att prototypande ses som ett sätt att tänka i design.

In this bachelor thesis, a prototype of a digital tool is designed, aimed at self-registering patient data in an emergency ward. Normally, patients not arriving by ambulance are treated in the order they enter the waiting room. Nurses performing the first examination—a triage—must ask the patient about their identity, previous medical history and similar questions, and enter this data into a new treatment case in the healthcare information system. It has been suggested that having the patient enter this data themselves would be beneficial, allowing nurses to concentrate on the medical issues. After gathering and analyzing data from observations and from interviews with the staff at a Swedish hospital, a prototype of a digital tool was designed, where patients step-by-step could enter the required data in the waiting room, thus saving valuable time in the triage. Benefits for the patient include receiving feedback about the number of persons ahead in line. The prototype was received favorably by test persons and by the staff, indicating that it could work as a model for a product to be put into work use.

This paper will detail the prototyping and subsequent production of an digital narrative experience utilizing the theories of Vladimir Propp. The prototype will examine the theories detailed in Propps Morphology of the Folktale. It will implement Propps narrative functions according to a general scheme, connected by connectives. The prototype will dynamically generate narratives according to this scheme. Finally, this paper will draw conclusions about the advantages of a Propp-based system of narrative generation and the narratives produced compared to other digital narratives, such as hypertext.

Product development can be taxing for the environment. When it comes to hardware products then a lot ofthe materials generally involved are based on finite resources such as fossil fuels. As the most commonlyused materials are rarely biodegradable, they often end up in landfills where they end up being harmfulboth to the environment and its inhabitants for a very long time. During recent years some companieshave started combating this through getting involved in the development and implementation of moresustainable alternatives. One of these companies trying to implement more sustainable materials isInteresting Times Gang, who now also wishes to develop new products by using mycelium - theunderground network of threads produced by fungi. This as mycelium poses a lot of sustainable propertiessuch as biodegradability, a high degree of moldability as well as being a cultivated resource rather thanbeing synthetic. This project serves to investigate what kind of product types are fitting for myceliumcomposites per request from ITG, as well as what kind of surface treatments are possible and fitting tomake the material more desirable. This with the intention of increasing awareness about the material withthe hopes of promoting it to a larger audience, enabling a transition towards more sustainable materialalternatives in the process. With the information gathered through research the project resulted in a sidetable that was designed and manufactured as a 1:1 scale prototype to showcase the possibilities of thematerial. This was done through a material driven design process which was divided into four steps:Understanding the material, Creating materials experience vision, Manifesting materials experience visionand Designing product concepts. Each phase included its own methods respectively and some of themethods include literature review, material testing, benchmarking, user testing, digital prototyping andmanufacturing to name a few. The project is a master thesis for the Industrial Design Engineeringprogramme at Luleå University of Technology performed during the spring of 2023.

Sustainable consumption is used to describe consumer behaviors which aim to reduce environmental impact. One way of measuring sustainable consumption is by tracking products’ carbon footprint. Today however, there is limited research on how carbon footprint information is influencing consumers online, and few online tools which allow consumers to track carbon footprints for specific products before the point of purchase. The purpose of the thesis is to design a sustainability tool which contains product level carbon footprint information as well as to test and evaluate how the information affects sustainable consumption. Theory from the fields of Human Computer Interaction and Carbon Footprint research was used in a multi-method qualitative study. Expert interviews and qualitative usability tests were conducted during the thesis as means of collecting empirical data. The study concludes that carbon footprint information should be introduced in the search phase of the consumer journey. The information should then progressively become more detailed as the consumer approaches the point of purchase. The study found that displaying carbon footprint information affects sustainable consumption positively in the tested online environment. However, personal preference and cost constitute a large part of consumers' choices as well. The study extends the research on carbon footprints by including results from an online environment. Future research should be conducted using quantitative methods to validate the results of this study on larger samples. Other product categories should also be tested as a way of investigating if the same consumption patterns emerge across different product categories. / Hållbar konsumtion används för att beskriva konsumentbeteenden med syfte att minska miljöpåverkan. Ett sätt att mäta hållbar konsumtion är genom att spåra produkters koldioxidavtryck. I dag är dock forskningen kring hur koldioxidavtrycksinformation påverkar konsumenter online begränsad, och få verktyg tillåter konsumenter att spårasina koldioxidavtryck för specifika produkter innan köp. Syftet med studien är att designa ett hållbarhetsverktyg med information om koldioxidavtryck på produktnivå samt att testa och utvärdera hur informationen påverkar hållbar konsumtion. Teori från områdena Människa-datorinteraktion samt Koldioxidavtrycksforskning användes i en kvalitativ multimetodstudie. Expertintervjuer samt kvalitativa användbarhetstester genomfördes under studien som ett sätt att samla in empirisk data. Slutsatsen från studien visar att information om koldioxidavtryck bör introduceras i sökfasen av konsumentresan. Koldioxidinformationen bör sedan successivt bli mer detaljerad när konsumenten närmar sig köptillfället. Studien påvisar att koldioxidavtrycksinformation påverkar hållbar konsumtion positivt i den testade onlinemiljön. Dock påverkar även personlig preferens samt kostnad konsumenternasval. Studien utökar forskningen om koldioxidavtryck genom att inkludera resultat från en onlinemiljö. Framtida forskning bör utföras med hjälp av kvantitativa metoder för att validera resultaten av denna studie på en större urvalsgrupp. Även andra produktkategorier bör testas som ett sätt att undersöka om samma konsumtionsmönster uppstår över olika produktkategorier.
