A special thanks to our supervisors at Volvo Group Trucks Technology Björn Wramstedt Rehammar and Susanne Almgren for their extensive support, encouragement and valuable feedback throughout the whole project. Special thanks also to Carl Jörgen Normark as supervisor from Luleå University of Technology for his calming and supportive words and valuable inputs throughout the project, especially regarding this project’s design process and research phase. We would like to send our appreciations to the drivers that were kind enough to let us join them during their work time for us to observe them and to the Volvo employees that made our ideation workshop a great experience. We also want to send our appreciations to the people we have met from Hällered proving ground which with their knowledge about truck driving and their positive spirits really boosted the project. At last we would like to thank everyone within the Driver Interface and Ergonomics team at the cab division at Volvo for all enjoyable lunches and fika breaks together and carrying words on the journey through the thesis project. Gothenburg 16th of June, 2016 Filip Lanneld and Filip Wessman Abstract This report covers a master thesis in Industrial Design Engineering at Luleå University of Technology (LTU). The thesis has been performed on behalf of Volvo Group Trucks Technology (GTT) and focuses on developing further application for use in a Camera Monitor System (CMS) replacing rear mirrors in trucks. The CMS could be the next evolutional step of the rear mirrors used in trucks today, increasing the truck drivers direct and indirect vision when driving while also having less aerodynamic resistance compared to regular rear view mirrors and hence in extension decreasing the trucks fuel consumption. Within CMS is an opportunity given to add tools and supporting functions for truck drivers to use in their work situations. This master thesis follows a user centered design process aimed to investigate, develop and present possible supporting functions to the CMS both relevant to the truck drivers working tasks and CMS main function. The project has been structured in six different stages; Research where a thoroughly theoretical study has been performed in subjects relevant to the master thesis project; Need analysis, gathering ethnographical data of truck driver behavior based on observations and interviews; Ideation, generating output of ideas for future concepts through workshops and creative methods; Conceptualization, Where concepts have been developed and evaluated; Implementation and Completion, where final concepts have been created, evaluated and implemented in an early stage prototype. The final result of this project is a concept containing several different applications developed to aid the truck driver in their common occurring work tasks. The concept is presented in descriptive text and visually in pictures in three different application packages, Awareness, Reverse assist and Bodybuilder, each one addressed toward different aspects of truck driving. The final concept has been evaluated using an early stage prototype of experienced truck drives. The projects result and outcome is finally discussed in the report were also several recommendations for eventual future work is given. KEYWORDS: Industrial design engineering, Human machine interaction, Camera Monitor System, User centered-design, Sammanfattning Denna rapport innefattar ett examensarbete i civilingenjörsutbildningen inom Teknisk design vid Luleå Tekniska Universitet (LTU). Examensarbetet har utförts på uppdrag av Volvo Group Trucks Technology (GTT) och inriktar sig på vidareutveckling av applikationer för användning i ett Kamera Monitor System (CMS) som ersätter backspeglar i lastbilar. CMS kan vara nästa steg i utvecklingen av backspeglar som används i dagens lastbilar genom att förbättra lastbilsförarens direkta och indirekta synfält under körning samt minska luftmotståndet jämfört med vanliga backspeglar och skulle därmed i förlängningen potentiellt minska lastbilens bränsleförbrukning. Vid implementering av CMS finns möjligheter att lägga till verktyg och hjälpfunktioner för lastbilsförarna att använda i deras arbetssituationer. Arbetet följer en användarcentrerad designprocess med inriktning på att undersöka, utveckla och presentera möjliga hjälpfunktioner till CMS som är relevanta både till lastbilschaufförernas arbetsuppgifter samt CMS huvudsyfte. Projektet har strukturerats och utförts i sex olika steg; Förstudie, där en grundlig teoretisk undersökning i ämnen relevanta till examensarbetet har utförts; Behovsanalys, där etnografisk information om lastbilschaufförernas beteenden baserat på intervjuer och observationer har samlats in; Ideation, vilket genererade idéer för framtida koncept genom kreativa metoder och workshops; Konceptualisering, där koncept har utvecklats och utvärderats; Implementering och färdigställande, där slutgiltiga koncept har skapats, utvärderats och implementerats i en tidig prototyp. Slutresultatet av detta projekt består av ett flertal olika applikationer utvecklade för att hjälpa lastbilschaufförer i vanliga återkommande arbetssysslor. Konceptet presenteras med förklarande text och visuellt med bilder i tre olika applikationspaket, Awareness, Reverse assist och Bodybuilder. Varje paket fokuserar på olika aspekter av användning och körning av lastbil. Det slutgiltiga konceptet har utvärderats genom en tidig prototyp av erfarna lastbilsförare. Projektets slutresultat och utfall har slutligen diskuterats i rapporten där även ett antal rekommendationer för eventuellt framtida arbete har angivits.
