This study aims to evaluate the preferences of drivers in Sweden, in regard to incar digital media players. As interfaces in cars, to some extent, are taking over thefunctionality of physical buttons and knobs, it is increasingly important for carmanufacturers to better understand what their users prefer.Through an analysis of current trends and measurements of user preferences, wehave identified areas for improvement and further development of these mediaplayer interfaces. These suggested improvements are as follows: • Using the screen real estate for important items • Emphasizing important elements by more efficient use of spacing andsizing • Removing or hiding menu items that are used sparingly • Using the concept of familiarity to create more user-friendly interfaces

Digitalisering av gränssnitt i bilar har lett till att fler funktionerimplementeras i gränssnitten, vilket resulterat i ett ökat informationsflödetill föraren. Detta har ökat behovet av att gränssnitt designas för transparens.Då räckviddsmätare i elbilar behöver hantera stora mängder information kanbrist på transparens leda till att förare upplever räckviddsångest. Att designaräckviddsmätare som kan förmedla stora mängder information så att förareupplever räckviddsinformationen som transparent kan därmed leda tillminskad räckviddsångest hos elbilsförare. Tidigare forskning har visat attadaptiva gränssnitt kan hantera och förmedla stora mängder komplexinformation, vilket visar potential för att transparent visualiseraräckviddsinformation till en förare. En litteraturstudie har genomförts därfyra dimensioner av transparens har identifierats, samt fyra designriktlinjerför hur adaptiva räckviddsmätare kan designas. Genom en designstudieimplementerades designriktlinjerna i tre designförslag. Designriktlinjernautvärderades sedan genom att implementeras i en körsimulator för attundersöka om räckviddsinformationen upplevdes som transparent avdeltagarna. Studien resulterade i lärdomar och insikter i hurdesignriktlinjerna kan implementeras vid design av adaptivaräckviddsmätare för transparent räckviddsinformation i elbilar. / Digitalization of interfaces in cars has led to more functions beingimplemented in the interfaces which have resulted in an increased amount ofinformation to the driver. This has increased the need for interfaces to bedesigned for transparency. Because range meters need to be able to handlelarge amounts of information, a lack of transparency could lead to the driverexperiencing range anxiety. Designing range meters that can mediate largeamounts of complex information which is perceived as transparent couldreduce range anxiety among electric car drivers. Earlier research has shownthat adaptive interfaces can handle and mediate large amounts of complexinformation which shows potential for transparently visualizing rangeinformation to drivers. A literature review has been conducted where fourdimensions of transparency have been identified, as well as four designguidelines for how adaptive range meters can be designed. Through a designstudy, the guidelines were implemented in three design proposals. Theguidelines were then evaluated through the design proposals in a drivingsimulator to examine if transparency was experienced by the participants.The study resulted in insights into how the guidelines can be implementedin the design of adaptive range meters for transparent range information inelectric cars.
