The use of dynamic display to improve reading comprehension for the small screen of a wrist watch

Abstract

This study explored the feasibility of displaying dynamic Chinese text on the screen of a wrist watch. Three design factors (i.e., dynamic display, presentation method, and speed) were examined to investigate their effects on users' reading comprehension under two different conditions of task types. The results of this study indicated the following: (1) There was no significant difference between leading display and RSVP in both single- and dual-task conditions; (2) Presentation method was a significant factor. The participant's reading comprehension was significantly better with the word-by-word format than with the character-by-character one in both single- and dual-task conditions; (3) The participant's reading comprehension was not significantly different among the three different speed settings in the single-task condition. However, participants had significantly higher reading comprehension scores under the slower speed settings of 150 and 250 cpm than under the faster speed setting of 350 cpm in the dual-task condition. © Springer-Verlag Berlin Heidelberg 2007.
