Through lexical decision task using Japanese two-kanji words and their corresponding transposed-kanji nonwords as stimuli, participants' performances depended significantly on outline shapes of constituent kanji characters. Compared to the words (or nonwords) with differently outline-shaped kanji characters, same outline-shape resulted in lower performance in the task.

Turn Signal Lamps of Vehicles that May Lead to Misjudgment of the Direction of Turn

Under the current vehicle regulations, physical demands are rather strict for turn signal lamps and taillamps (or brake lamps). There are, however, no restrictions on the design or the arrangement of them. A question is raised here that in some configurations of turn signal lamps and taillamps, a driver seeing the lamps might misjudge the direction of turn. That is, we claim a potential danger that, if vehicle's turn signal lamps are placed inner position than taillamps, misjudgment could occur. We performed psychological experiments on this issue, and confirmed our claim.

When we speak aloud there appears unconscious and inevitable head movements. We used image processing technique to measure head positions and rotations. As a result, we could perfectly classify eight participants.

We examined a Japanese text entry method which uses four arrow keys to select desired kana on a table of the Japanese syllabary. A theoretical study showed the increase in text entry efficiency by rearranging the table. We made a user experiment and obtained a result that support the theoretical prediction.
