This is a Ph.D. dissertation.

The thesis presents findings from five readability studies performed on mobile devices. The dynamic Rapid Serial Visual Presentation (RSVP) format has been enhanced as well as eye movement modelling. The novel formats have been evaluated against other common presentation formats including Paging, Scrolling, and Leading in latin-square balanced repeated-measurement studies with 12-16 subjects.

Apart from monitoring Reading speed, Comprehension, and Task load (NASA-TLX), Eye movement tracking has been used to learn more about how the presentation formats affects reading. It is explained why readability on mobile devices is important, how it may be evaluated in an efficient and yet reliable manner, and finally, Predictive Text Presentation is introduced. The format is based on RSVP and combines linguistic chunking and adaptation with eye movement modelling to achieve a reading experience that can rival traditional text presentation.
