Sammanfattning

Maps in mobile devices are appreciated aids for exploring andacquiring information about different geographical locationsaround the world. In these maps, you can, among otherthings, get directions, find restaurants in the local area andnavigate in public transport. To an increasing extent the mapsalso contain real-time data, i.e., information that is current andreflects reality and this information is continuously updatedand can inform the user about traffic situations, extent of airpollution in a specific area or delays of public transport. Theinformation in a map is primarily conveyed visually, whichmeans that people with visual impairments not always canaccess the information that is presented on the screen. Theexisting research on accessibility in maps for people withvisual impairments does not deal with real-time data, and thepurpose of this study was to identify which factors that affectsthe accessibility in maps that contains real-time data and withthese findings develop a model.A qualitative study has been conducted where the datacollection consisted of observations with participants whohave visual impairments to varying degrees observed a mapcontaining real-time data. The observation was followed bysemi-structured interviews. Data were then analyzed using atheoretical framework based on factors that affect accessibilityin mobile maps. Data that could not be associated with theexisting factors were then analyzed thematically.The study shows that factors that affect the availability ofmaps are also significant when the map contains real-timedata. In addition, the study shows the importance of beingable to alter the appearance of the real-time data and howmuch and which real-time data is presented to users.
