Welcome to Ujima Lab.
My research work is reading performance and educational special need on the people with visual impairment. Now, I am developing software to learn the character "KANJI".

- (Purpose) The latencies were focused on factor that reading speed turned around critical print size (CPS).(Method)We measured latencies of reading in order to know the word recognition time. There are two factors that have factor of Low-vision simulation (two levels: simulated or no-simulated) and character size around CPS(five levels). Dependent variable was latencies.(Result)In results of ANOVA, Visual acuity didn’t have main effect significantly. Character size had main effect significantly. In result of LSD, latencies of reading were longer under CPS.(Conclusion)We showed that latencies of reading were longer under CPS, and this case was explained by prolonged viewing hypothesis. This result confirmed that longer time in phases of input the each word produced lower reading speed under CPS.

- Determining the Size of Characters for Large-Scale Projected Presentations for People With Low Vision: A Method Using the Results of Reading Ecaluation Tests

- This paper concerns two experiments; one, which involved simulated low vision in people with normal vision and one, which involved people with actual low vision. The purpose of the experiments was to determine the usability of the critical size of characters in projected presentations at a distance. The first (simulated low vision) group was tested considering two factors; character sizes (3 levels) and reading styles (2 levels). The results from the first experimental group showed that reading speed was significantly faster in cases where print size was critical size (or larger) than it was in cases where print size was smaller than the critical size and that there was interrelation to the results of the reading evaluation tests, suggesting that the critical print size may be used as a standard in determination of character size for large scale projected presentations. Some results of the second experimental group showed great similarly to the first group, however there were cases when the results didn’t exactly match that of the first group. The results of these experiments suggest that although the critical print size may indeed serve as a good standard in determining the character size for people with low-vision, it is also important to consider first-hand opinions of such readers and make necessary adjustments.

- Most of the documents and textbooks usually used in school for low-vision are printed matters. The most preferable character size, font and other properties in a printed matter, individually depend on each low-vision. We herein attempt to propose new teaching materials for low-vision; Hyper Text Markup Language (HTML) contents which work on personal computers. Each low-vision is able to make his/her own choice of size and fonts. To prove how effective the contents are, an examination for low-vision is carried out. It is found that students' reading speeds in HTML matters are as high as in normal printed matters. In addition, accessibility (search time) is faster in the HTML matters than in printed matters.
