We have analyzed the impact of text visualization on the screen for the information processing process.
The dynamic development of the Internet enforces new standards for presentation of texts in order to facilitate their efficient processing. In an experiment conducted by us, we checked the extent to which the text visualization translates into effective reading and memorization. Using the device for testing eye movements (eye tracker) as well as testing text and information retention (recalling information from memory), we investigated the reactions of 40 participants.
The results obtained in that manner showed differences in reading performance; it was found that scrolling in the requires more processing time compared to reading paginated text, while the results of the information retention tests were almost identical. In addition, we observed significant differences in the eye movement for reading the middle paragraphs. This may be due to the fact that the division of text into smaller section has been suggested, and therefore it easier to remember * .
Results of the experiment were presented at a conference in Marseilles.
* Dependent variables come from the eye tracking data and apply to the average period of fixation (sight concentration on the observed field) and the text memorization tests, which were carried out at the end of the experiment. We investigated the relationship between the reading efficiency when scrolling through the text in comparison with paginated text, along with the text presentation on the screen (with or without paragraphs).
