A large ocular surface are (OSA) induces eye irritation and eye fatigue because the eye surface is highly sensitive to various irritants such as dust, heat, dryness, air flow, etc. The author considered that OSA must be one of the useful indices of visual ergonomics. In order to propose a comfortable visual display terminal (VDT) workstation layout, this paper showed two practical application of OSA measurements. One was the comparison of OSA in different types of visual tasks to extract the features of OSA in VDT work, the factor affecting OSA was not cathode ray tube (CRT) height itself but the distance between the CRT and keyboard. Thus, the workstation which the CRT be set close to the keyboard is recommended to realize comfortable VDT workstation to keep a smaller OSA in VDT users.

In this study, we tried to clarify following four aspects of eyesight. (1) We examined daily change of eyesight in 10 volunteers for 1 week. The result showed a change to 0.37 on an average. (2) We examined the influence of the finger rotation exercises on the eyesight of 15 junior high-school students. Immediate eyesight improvement to an average of 0.35 was observed. Improvement of both intellectual ability and phusical flexibility followed to this change. (3) We examined the influence of speed reading training on eyesight. As a result of two day training, eyesight improved by about 0.2 on an average. In a class which was held one time (three hours) a week, eyesight improved by about 0.2 on an average. We concluded that both finger rotation exercises and the training of speed reading let us improved eyesight.

The aim of this study was to evaluate the relationship between eye movements and the skill of measuring blood pressure. Four proficient nurses were selected as the subjects and their eye movements while measuring blood pressure were analyzed comparing with their motions. Eye movements were detected by TV type eye camera (NAC EMR-7)
The main results were as follows; (1) Each viewing ratio was changed by the contents of the motions. (2) These subjects tended to look at next viewing objects to perform their next motions smoothly. (3) Proficient nurses tended to use their hands instead of the eye sight.

Japanese anti-aliased font evaluations

This paper describes a study on effectiveness of Japanese anti-aliased fonts. This study consists of two experiments. In experiment-1, a subjective evaluation was carried out by using limited number of anti-aliased fonts, in order to estimate the effectiveness of Japanese anti-aliased fonts. As a result of the experiment-1, it was found that anti-aliasing is more effective for small characters (15×16) of Kanji/Kana characters. In experiment-2, new character sets of Japanese anti-aliased fonts were created, and both user performance and preference were evaluated. The results indicated that the proofreading speed on Japanese anti-aliased fonts was significantly faster than that on bi-level (traditional) fonts, and that the anti-aliased fonts were significantly preferable to the bi-level fonts.
Keywords: anti-aliasing, gray scale, fonts, proofreading, readability

This paper was prepared as the proceedings of the 3rd joint symposium hosted by JERS system related research groups, held last March at Inter-University Seminar House located Hachioji, Tokyo, Japan. But this short report is not exactly the same as I presented before.
One of the reason for that is I also made another oral presentation at the symposium S5 last June at Sendai Civic Auditorium concentrating to international political backgrounds of the item.
Contents: 1. Introduction (the significance of new JIS Z 8513, the Japanese version of ISO 9241-3)
2. The relation between JIS Z 8513 and JIS X 6041, as well as ISO 9241-3 and BS 7179:Part 3
3. Applicability of the type of electronic display device (CRT and/or FPD?)
4. Summary (ISO-9341-3 should not be ‘IS’ but ‘TR’, proposal for the future)
Keywords: Visual ergonomics, Japanese industrial standard, International standardization
