Abstract: With the evolution of the technology, mobile devices have gradually become an indispensable part of life. Meanwhile, the display technology is converted from 2D display to 3D display. In this study, we investigated the effects of display technique, image content, and dynamic & static environments on user performance of a auto-stereoscopic mobile phone. Eighteen subjects were recruited in this study. A three way full factorial design was used to investigate the effect of display technique (2D and 3D), environment (a controlled laboratory, and a carriage of a Mass Rapid Transit (MRT), and a car), and image content (picture, video and game) on usability and the change of critical fusion frequency (CFF). The ANOVA results indicated that display technique was significant on usability and the change of CFF, where viewing the 3D display induces more fatigue than viewing the 2D display. The results also showed that environment was significant on usability and the change of CFF, while the performance in a laboratory is better than that in a carriage of MRT and a car. Finally, the results indicated that image content was significant on the change of CFF, while highest visual fatigue was found in game playing.
