Papers

  1. Research paper (scientific journal) Joint Influence of outline shapes of Japanese kanji characters on reactions to lexical decision task of two-kanji compound words Hiro-Fumi Yanai, Kenta Hayashi IEICE Transactions on Information and Systems J-99D/ 1, 97-99 2016/01/01 1881-0225 10.14923/transinfj.2015HAL0003 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.
  2. Research paper (scientific journal) Joint Turn Signal Lamps of Vehicles that May Lead to Misjudgment of the Direction of Turn Hiro-Fumi Yanai, Naoyuki Numasawa IEICE Transactions on Information and Systems J-98D/ 11, 1402-1410 2015/07/15 1881-0225 10.14923/transinfj.2015JDP7013 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.

We used image processing technique to measure head positions and rotations. As a result, we could perfectly classify eight participants.

Research presentations

  1. Poster presentation Estimating carrier’s height by accelerometer signals of a smartphone Human-Computer Interaction International 2016/07 URL The aim of this study is to estimate height of a carrier (owner) of a smartphone by using single three-axis accelerometer signals. We found that the accelerometer signals collected while a carrier goes up the stairs contain features that are correlated with height of the carrier as high as r = 0.801. Apart from potentially useful applications of the result, there might arise a privacy issue in using smartphone since approximate height could be acquired in this way. Although, in general, height is not regarded as private information to be worried about, if someone thinks his/her height belongs to privacy, it should be protected against leakage.
  2. Oral presentation(general) Turn signal lights that may lead to misjudgment of the direction of turn, Part 2 2014 JSAE Annual Congress (Spring) 2014/05 Under the current vehicle regulations, physical demands are rather strict for turn signal lights and taillights (or brake lights). There are, however, no restrictions on the design or the arrangement of them. In our previous report, we claimed a potential danger that, if a car's turn signal lights are placed inner side than taillights, a driver following the car might misjudge the car's direction of turn. We performed psychological experiments on this issue, and confirmed our claim.

  5. Oral presentation(general) Turn signal lights that may lead to misjudgment of the direction of turn 2013 JSAE Annual Congress (Spring) 2013/05/22 Under the current vehicle regulations, physical demands are rather strict for turn signal lights and brake lights (or taillights). There are, however, no restrictions on the design (the shape) or the configuration of them. A question is raised here that in some configurations of turn signal lights and brake lights, a driver following a car might misjudge the direction of turn in spite that the car is signaling the correct direction.
