The intent of this study is to investigate some critical factors that affect legibility and visual fatigue while reading on an electronic-paper display in terms of ergonomics. Anti-reflection surface treatment, ambient illumination, and bending curvature are taken into account to evaluate their effects by using the method of letter-search task. The results showed that the surface treatment with high degrees of anti-reflection significantly improved the legibility and reduces visual fatigue. Thus, electronic-paper manufacturers may choose a much better surface treatment in order to meet ergonomie demand. In addition, the findings in the present study also indicate that subjects reported less visual fatigue on a bending surface of a visual display unit, in comparison with a plane surface. It is proven that these ergonomie evaluations for electronic paper provide manufactures with useful information to design suitable products for users.
