Publication #16 - 基本欲求を満たすウェアラブル・コンピュータ:子供と高齢者の特徴 (Fundamental Needs in Wearable Computing: Specificities of Young People and Older Adults)

My 4-pages paper "基本欲求を満たすウェアラブル・コンピュータ:子供と高齢者の特徴" ("Fundamental Needs in Wearable Computing: Specificities of Young People and Older Adults") written with 橋爪宏達 (HASHIZUME Hiromichi) was published at the 日本バーチャルリアリティ学会第12回大会 (12th annual conference of the Virtual Reality Society of Japan) the 21 September 2007 (see post on VRSJ大会 2007).

Abstract: Young people and older adults have specific needs reflected by their growth and decline, activities and use of technology. First, we briefly present their cognitive, physical, and sensory characteristics. Then, based on impacts on fundamental needs, we discuss dedicated systems that exploit wearable computers, and the proper design of such systems. Our most significant contribution is to provide the first overview of age-related specific needs in wearable computing.

日本バーチャルリアリティ学会第12回大会 (12th annual conference of the Virtual Reality Society of Japan) in 福岡 (Fukuoka, Japan), 19-21 September 2007

The 日本バーチャルリアリティ学会 (Virtual Reality Society of Japan) organized its 12th annual conference in 福岡 (Fukuoka, Japan) between the 19 and 21 September 2007. My talk "基本欲求を満たすウェアラブル・コンピュータ:子供と高齢者の特徴" ("Fundamental Needs in Wearable Computing: Specificities of Young People and Older Adults") occurred during the session on wearable computing.

After my 10-minutes talk, the chairman asked me to discuss the importance of psychology in wearable computing. This request was pertinent because Japanese research usually focuses on wearable technologies without considering broad issues related to human factors. I indicated that psychology, culture, and age considerations are critical for the creation of wearables suited to the general public, and for the adoption of the technologies. One could ignore this point, develop technologies and wait for somebody else to properly exploit them but this has several drawbacks: (1) nobody may do the proper work because our wearable community is quite small, (2) some features may conflict with human needs and may be difficult to correct afterwards, (3) delays in technological adoption limits potential users' benefits and inventor's financial benefits.

Before finishing, a researcher working on head-mounted displays asked: "How shall we prepare our experiments with children?". I indicated that this is a thorny issue because experiments with children raise ethical problems: our experiments may negatively affect children's health or development due to our ignorance regarding human development from birth to adulthood. Therefore we should at least work with experienced and authorized psychologists and medical doctors.

Read the post "Publication #16" for details about the publication. An overview of my work on young people and older adults was presented two weeks before during a seminar (see related post) at 연세대학교 (Yonsei university) in 서울 (Seoul, South Korea). Details about the specificities of older adults were published in France in April (Publication #12), and details about young people will be presented in South Korea in November (Publication #17).

The conference went on finely and I could benefit from a tour of 九州大学大橋キャンパス (campus Oohashi of Kyushu university). I was particularly impressed by the 環境適応研究実験施設 (research center for human environmental adaptation), which was created to clarify the conditions for healthy and comfortable living environments, with a focus on human environmental adaptability. Its 744m2 building contains: (1) an hyperbaric & hypobaric chamber to simulate deep sea and high altitude air pressure, (2) an illumination chamber to test feelings about light and its impact on e.g. the biological clock, (3) a combined factor chamber with control over air temperature, air humidity and air velocity, (4) a thermal chamber to simulate cold places, (5) a living environment chamber with a bathroom, kitchen and toilets but without windows and clocks, (6) a water immersion chamber, and (7) a thermal radiation chamber. The knowledge gathered by this center as well as the potential for experiments are particularly suited to the development of wearable computers and intelligent environments dedicated to the improvement of the general public's quality of life.

Finally, I discussed with 佐藤 誠 (SATO Makoto), who was my supervisor at 東京工業大学 (Tokyo Institute of Technology) in 2002, and who is still developing haptic systems such as the SPIDAR.

I was invited by 조 길수 (CHO Gilsoo), director of the 스마트의류 기술개발연구소 (smartwear research center), to give a talk about the general public's needs in ubiquitous computing at 연세대학교 (Yonsei university) in 서울 (Seoul, South Korea) on 7 September 2007. I strolled in the campus of the university for the first time, discussed with specialists in smart clothing, and saw prototypes.

I appreciated very much the director's warm welcome and our discussions about 연세대학교 (Yonsei university), the Korean industry, culture and education, the relationships with Japan, and the state of research in smart clothing. 생활과학대학 (The college of Human Ecology), where she is a professor, is quite exciting, with sections in clothing & textiles, food & nutrition, housing & interior design, child & family studies, and human environment & design. This academic setting is very attractive for its strong link with quality of life and human basic needs.

My 1-hour entitled "General Public's Needs in Ubiquitous Computing: Design Based on Psychology, Culture and Age" was based on former works about the perception of smart clothes by the general public (Publication #6, Publication #8), on recent works about the specificities for older adults (Publication #12), and on unpublished works about the specificities for young people (publication #16 and publication #17). Due to a trend for the integration of intelligence in clothes and houses, students and researchers in fashion, interior design, textile, and psychology attended the presentation. They asked questions about the design of the questionnaires used to evaluate the general public's perception of technology, the cause of the rejection of artificial intelligence to control smart clothes in France and Japan, and the transfer of findings about wearable computers to intelligent environments.

Finally, a small group of Koreans working on smart clothes presented the group's activities, answered my questions, and showed me prototypes of smart clothes while explaining the techniques used and challenges. Interesting elements included textile keypads, and textile connectors. The keypads were used on sleeves of small tops for children, and the textile connectors notably transmitted data from sensors detecting ultraviolet light, embedded in a ski suit. The garments had been featured at the fashion show "Smart Clothing 2007" held in 서울 (Seoul) the 11 May 2007.

Globally, the visit was very satisfactory and enriching.

Publication #15 - Fundamental Needs in Wearable Computing: Constraints on Features & Universal Access

My 6-pages paper "Fundamental Needs in Wearable Computing: Constraints on Features & Universal Access" written with 橋爪宏達 (HASHIZUME Hiromichi) was published at the 10th IFAC symposium on Human-Machine Systems the 4 September 2007 (see post on HMS 2007).

Abstract: The creation of wearable systems should take into account human fundamental needs and diversity as well as ecological settings but they are often neglected in favour of core functions. To guide further research and development, we present and discuss issues related to the variety and evolution of human characteristics, psycho-social needs, fashion, legal frames, interactions between technologies, and physical environments. These elements highlight critical assumptions as well as constraints imposed on the features of wearable computers, and on universal access.

10th IFAC symposium on Human-Machine Systems in 서울 (Seoul, South Korea), 4-6 September 2007

The International Federation of Automatic Control (IFAC) successfully organized the 10th international symposium on Analysis, Design, and Evaluation of Human-Machine Systems in 서울 (Seoul, South Korea) between the 4 and 6 September 2007. My talk "Fundamental Needs in Wearable Computing: Constraints on Features & Universal Access" occurred during the first session on interface design.

My 15-minutes talk went well and I was just asked one question at the end: "Are you developing a system based on this work?". The answer was yes: we are developing a system for bonding and support within the family. This system should deepen our understanding of human needs in ubiquitous computing, and hopefully validate more strongly the work done so far. Read the post "Publication #15" for details about the publication.

The conference was well-managed every day: the talks were properly selected, most speakers were present, excellent lunches and dinners were included, and a Korean-style show with music and songs gave a charming touch to the banquet.

I met a few interesting people including a South Korean psychologist working for 웅진코웨이 (WoongJin Coway), who was interested in the implications of my research for the design of robots for the general public. We may discuss this more deeply during my next visit.
