    It is becoming very hard for consumers to select products and to evaluate if they realized satisfy thier requirements. The situation is the more disorderly as miscellaneous and enormous amount of products are offered the consumers. To overcome this problem, it should be realized that the human factors researches have to fill an important role in improving the man-machine system not only in machines, tools and instruments but in the articles of common and daily use. New articles having better quality and performance should thus be developed.
    The recent development in the field of industrial design has vontributed to improve the quality of consumers' goods, since the fundamental thought of design is to attach great important to human characteristics and this idea is consistent with that of ergonomics. The relationship between design and human factors was discussed and examples of research approaches to consumer products were introduced. Some future problems of consumer products design were also referred to.

    The reports on the functional analysis of table-wares (cups, dishes and metaltools) are rather seldom in our country. Yokoyama et al. (1959) reported the results on the tea knob and Yanase et al. (1964) examined the water pot handle from various view points of ergonomics. It is very important and is a basio problem for ergonomic study to know the actual hand size of Japanese and the extensive were carried out by Yanase et al. (1962) and Uchimura et al. (1967). The feeling test of the handle of a kitchen knife (Japanese style) was done by Suematsu et al. (1967).
    On the ergonomic aspect of kitchen furnitures, Omori (1964) and Inaba et al. (1966) determined the height of kitchen work-tables as 80cm for Japanese women from metabolic test. Kurimasa et al. (1967) insists that 80cm height is rather too low for Japanese women on the basis of experiments in which they employed such light work as dish-washing, while Omori and Inaba et al. used rather heavy taskwork in thier metabolic research.

    Room cleaning work by an electric vacuum cleaner was studied. Cleaning performance respiration rate and pulse rate during cleaning work using various types of electric cleaners were compared. A cleaner with its motor part built in the wall showed the least cleaning load. Floor type or shoulder type cleaners were demonstrated to be less fatiguable than stick type or hand type cleaners respectively. One hand control could be done with lower pulse rate level. The angle of the suction nozzle should be variable. A handle with an angle of 22.5 and the height of around 750mm considered to be the best.

    The popularization of ready-made clothes through the mass production method clearly showed the necessity of extracting such human factors as fitness for physical and bodily movement, sanitation and safety as a step to improve comfortability and easiness in wearing, ewpression of grading and sizes of clothes is also essential to help consumers to select the most suitable clothes for them.
    In the case of the suits for children, attempt is also made to decide prerequisits for children's suits according to children's physical, physiological and psychological characteristics and easiness in wearing as well as the care by thier mothers in addition to abovementioned factors.
    A plan to compile a checklist to give the objective evaluation of of the design of clothes is also being studied by an overall committee consisting of representatives of consumers, manufacturers, retailers and designers.

    Human engineering approaches are playing an important role in developing, produoing and improving passenger cars as consumer goods. An outline of our activities conducted Through the Japan Ergonomics Research Society, and Society of Automive Engineering of Japan, was offered and also a summary of the existing regulations for traffic safety.
    The present report consists of the brief notes on the following items:
    1) Statistical trend in Japan's automobile production, 2) Anthropometric survey of car passengers, 3) Dimensional measurement of automobile body, 4) Development of Japan's original J-SAE 3DM and Impact Test Dummy, 5) Manipulating force of gerashift lever, 6) Operational work space of accelerator pedeal, 7) Relations between steering, seat and pedals, and 8) Brake pedal operation and stopping distance.

    Muscle activities during cycling of 4kg/msec. were electromyographically studied by means of a bicycle ergometer worked up by T. Toriyama. Cycling speed was 85rpm.9 positions of the pedal shaft in relation to the handle and saddle sites were examined. The distance of the handle from the saddle center was 45-65cm. Through finding the pedal position where the least electrical activities of m. gluteus maximum, m. rectus femoris, m. biceps femoris and other main muscles contracting in cycling were shown, the optimum pedal positions proved to be demonstrated by the proposed method. It seems to be important to have determined the limit conditions of the handle, saddle or pedal positions at first.

    Some human factors related to visual displays by means of the picture transmission were reviewed and discussed. The transmission system should satisfy the demanded picture quality. Thus, for example, the flickering frequency or the number of beam lines in television display may be determined. Existing commercial TV sets, however, seem to be unsatisfactory from ergonomic viewpoints. That is also the case for NTSC chromatic display system. It indicates the important of ergonomic and fatigue factors in CRT displays. The distortion of the picture and the noise signals were discussed as fundamental factors affecting the picture quality. The legibility problem of direct letter transmitting was also discussed. In order to reduce the visual fatigue by television display, the NHK has recommended the optimum televiewing conditions for public.

    A short history of human factors studies on furnitures was reviewed. The author paid special attention to the design of seats, desks and beds. As a practical example, the revision of the Japanese Industrial Standrad for school furnitures based on an ergonomic group study can be cited. In the near future the dynamic somatometry, comprehensive examination on the furniture layout, application of feeling tests and studies on quantification of cushion characters and others should be promoted.

    Reaction time of recognizing a prescribed pattern with noise figures and its relation to the eye movement were studied exprimentally. 4 random patterns of each 8 hexagon cell figures were presented to the subjects by means of a slide projector. Each cell had a visual angle of 1, and each pattern was presented without or with 10, 20 30 or 40 noise cells. Eye movement was recorded by an eye camera and a videorecorder. The reaction time was the more prolonged, the more noise oells were presented. A positive correlation between the reaction time and the fixation frequency of eyes was found. The average entropy around the gazing point was calculated and it proved to be also correlated closely with reaction time, if the former was less than 2 bits. Presentation of noise figures seemed to have stronger effects on the reaction time.

    Details of design and construction of a VTOL flight simulator, completed in March 1966, are given this report. The one-man cab has conventional seating, controls and instrumentation in which CRT and TV type displays are involed. A television camera with 6 degrees-of-freedom is used to acquire a visual scene of landing-approach below a 120m ceiling. The model represents an area 2600m by 100m at the 1:400 scale. A projected or monitor image may be presented to the pilot as visual aids. This system is controlled through an analog computor which has been programmed to account for vehicle dynamic response to pilot's control input.
