Comparison of eye fatigue among readings on conventional book and two typical electronic books equipped with electrophoretic display and LC display
Abstract:We have measured eye fatigue after each 90 minutes of reading on a paper (book), electronic paper (book reader using electrophoretic reflective display), and LCD (backlight type liquid crystal display). Increase of Near Point Distance was measured in each subject as an objective index. Subjective impression of eye fatigue was answered by subjects using fatigue scale of 5 ranks. As a result, the biggest fatigue was indicated by LCD while the smallest fatigue was indicated by a conventional paper book.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
