Typografi och läsbarhet för mobila enheter : En studie i hur typografiska element påverkar läsandet på mobila enheter

Sammanfattning: The goal with this thesis is to explore previously used and trusted design guidelines on the new and relatively unexplored platform that is mobile devices. This type of platform is today the most common way for people to access written text, but the typography and design of this text is not always based on research. The thesis is limited to focus on how typefaces and type size affect readability. Based on the definition of readability presented in the thesis both subjective and objective measurements have been produced. These are for example: the reader's personal preference, reading speed, reading comprehension, scroll distance and touch-interactions. Through an analysis of the unique way readers interact with text during reading on a mobile device several objective measurements can be produced. Models for analysing this kind of data have been used and presented in prior studies. The data collection methods utilised in this thesis are: information and literature search, surveys and experiments. The collection of data is mainly conducted through a web application adapted to mobile use which has been published for the participants of the study. The results show that typefaces do not have any significant correlation with readability on text for mobile devices. However, type size has a greater effect on both the subjective and objective measurements of readability. The subjective measurements concerning type size have more of a spread regarding which size was perceived as being the most readable. The type size that generated the best results in the objective measurements was 18pt. When the type size increased so did the reading speed, but the reading comprehension decreased.
