Physical Properties and Onomatopoeia-Characterizing Onomatopoeia in Relation to Shaking-

( Takashi Toriizuka ) 한국감성과학회 2014 춘계학술대회 Vol.2014 No.-

Shaking is very familiar with us in our everyday life. I n academic field, we describe the properties of shaking by using the frequency and amplitude. But in our everyday life, general people rarely use those indexes to describe the shaking. General people use onomatopoeia instead, like yura-yura, gata-gata or gura-gura…to describe them. The purpose of research is to characterize those onomatopoeias related to shaking in terms of their physical characteristics such as frequency and amplitude. Through this research, basic data and findings for the standardization for the description using onomatopoeia were obtained. The relation among onomatopoeia, feeling and physical properties has been cleared. We could get some basic indication for making guidelines for human centered design by onomatopoeia, e.g. if someone said the word gatagata, gachagacha.... this means he/she got scare and feel large shaking. If so, his/her scare would be lighten by the improvement which is focused on the motion acceleration, sound (jarring or rattling), etc of the building.

Characterizing Wooden Texture Using the Affective Engineering Approach

( Mio Ikeda ),( Takashi Toriizuka ) 한국감성과학회 2014 춘계학술대회 Vol.2014 No.-

There are a lot of furniture and building materials made of wood around us. Some people buy them to stick to tree species and characteristics. However they probably don`t have expert knowledge regarding to woods. Therefore people rely on their senses (sight, smell and touch) when choosing woods. The problems that, example, we feel like a good looking wood, but the feel is bad actually use. Furthermore, picking one of kind of woods, they confuse at large home center. I consider that an index such as the choice of wood sensuously will get to choose the wood easily. The purpose of this research is to identify impression of woods. In addition to characterize woods in term of affective (kansei) engineering. The impression evaluation were examined using fourteen woods with three conditions (sight only, without sight and all sense). The results, the yellow pine, the hinoki and the walnut were woods which everybody feel attracted, but the hard maple, the red oak and the kusu were not feel attracted from relation the level of attraction and the standard deviation. The difference of senses choosing woods made the level of attraction change. Woods which have common impression between sight, sense of touch and smell were become the high level attraction.

Good Practices of Ergonomic Science Communication in Japan

Yasuyuki Yamada,Takeshi Ebara,Takashi Toriizuka 대한산업공학회 2022 Industrial Engineeering & Management Systems Vol.21 No.4

Science communication (SciComm) is a practical activity that maximizes the utility of academic findings, knowledge, and information. This study examined the good practices and future issues of SciComm in the field of ergonomics, in Japan. The first good practice was the establishment of the SciComm Committee in the Japan Human Factors and Ergonomics Society (JES) in 2020. The second was the ErgonomicThon workshop—an ergonomic Ideathon to discuss new ideas regarding the uses of ergonomic findings. The third was the original SciComm program using infographics to promote the use of ergonomic words in social networking service (SNS) communication. The fourth practice was the challenging online fieldwork conducted using the Google Street View. The last practice was the virtual convivial party held at the 62nd conference of JES in 2021. Based on these practices, we suggest the following three future issues of SciComm: (1) promotion of SciComm, beyond times of crisis; (2) development of ergonomic guidelines for SciComm; and, (3) promotion of online SciComm within the information society. This study outlines the importance of sharing good practices and future issues of SciComm that will help spread the movement of the SciComm in the field of ergonomics.

A study of "Listen" and "Hear"

Ryuta Baba,Yuki Mochizuki,Takashi Toriizuka,Yoshinori Horie 대한인간공학회 2010 대한인간공학회 학술대회논문집 Vol.2010 No.5

Recently, the portable audio players such as iPods are widespread. In this context, more people listen to music with headphones, and some people accidents such as the bicycles, cars or trains happen. People with headphones are shut off from surrounding sounds. So they can’t perceive sound information necessary to avoid the accidents. That’s why they have accidents. Then in this study it pays attention importantly of the balance of "Listen" and "Hear" that is the act that humans obtains outside auditory information as an influence that the headphone use in outdoor exerts on the perception function of aural, and in the present study, the measurement of the P300 event-related-potential(ERP) is used and examined. “Listen" means outside auditory information is actively obtained."Hear" means outside auditory information is felt passive with the ear. The tests subject the schoolboy who was listening to music daily by the healthy physically and mentally. Experimental conditions set three conditions when a normal headphone is used and when the headphone is not used when it uses noise-canceling headphone. The experimental methodology is tried by the ‘oddball’ Paradigm using the auditory stimulus that can be two kinds of discern it. The auditory stimuli use the bell sound of the bicycle and the running sound of the car. Target stimulus is a bell sound of the bicycle. Non-target stimulus is assumed to be a running sound of the car.

A study of the effect of BGM on the impression of shop space

This study is concerned with a correlation between the image of shop made by the collaboration of shop space and BGM, and a customer's relaxation. The environment which a customer can relax is demanded in a shop like a beauty parlor. Song selection of BGM and a space design are important for it. Then, in order to measure correlation between the image of a shop and a customer's relaxation in an experiment, the set which imitated the beauty parlor was considered. It projects the image of a beauty parlor on the screen of three directions, and also sounds music from the speaker installed in the ceiling. In the experiment, five genres of music (Classic, Jazz, Bossa Nova, Hip Hop and Rock) and four kinds of space (Fresh image, Warm image, Noisy image and Simple image) were prepared. The subjects experienced five genres of music, four kinds of space, and 20 kinds of combination at random, and the subject's impression was written down in the evaluation paper. As a result, music had influenced the customer's relaxation. At the shop which offers a relaxation to customers, music of Jazz or Bossa Nova and a warm space are effective. Simultaneously, music of a Rock and a noisy space checked that it was not effective, either. Furthermore, when making the space design of the shop the simple space, it has checked that an impression and a customer's relaxation was also changeable only by song selection of music. Finally, when designing the shop which provides a relaxation to customers, comfortable, become composed, and peace of mind are important elements.
