“…Previous studies (e.g. El Falou et al, 2003;Porter et al, 2003;De Carvalho andCallaghan, 2011, Smith et al 2015) have shown analytically that sensation of overall discomfort increases over time. Through a series of studies involving motion and long-duration sitting, Mansfield et al (2014) showed that discomfort increases both with vibration magnitude and with sitting duration, and that the presence of vibration causes an increase in the rate of discomfort onset.…”

“…Mansfield et al (2014) and Mansfield et al (2015) demonstrated that a 'showroom' or static analysis is not sufficient to asses a seat's comfort as it fails to encompass many of the other factors affecting overall car seat discomfort. Porter et al (2003) demonstrated that short term evaluations of discomfort are inadequate as the effects of fatigue and long term sitting have not been accounted for.…”

Discomfort in vehicle seats is a multifactorial problem with large increases in discomfort occurring during extended duration driving. Due to the nature of driver discomfort, previous research has found it difficult to accurately quantify long term driver discomfort via the use of objective measures. This paper reports a laboratory study that investigates a novel objective measure of long term driver discomfort and its correlation with subjective discomfort ratings. Analysis of driver's seat fidgets and movements was conducted over the duration of a 140 minute drive on a driving simulator in addition to collecting subjective ratings of discomfort. It is shown that as subjects' subjective discomfort increases, the frequency of subjects' seat fidgets and movements increases congruently. A large correlation is observed between the subjective and objective measures of driver discomfort and provides the opportunity for long term discomfort evaluations to be made via remote monitoring; removing the need for subjective assessment.

“…During sitting, discomfort increases through time. Porter et al [26] reported an increase in discomfort during driving road trials of 135 minutes sitting in a car seat. Smulders et al [8], indicated that the discomfort in an airline business class seat increases in time.…”

Abstract. Within this special issue, different aspects of the environment are studied: aspects that are distant from the human body, close to the body and touching the human body. Consequently, different human senses are involved in these studies as well as the different consequences and effects on the brain and human behaviour. This special issue also highlights many remaining questions about the effects and relationships between environments and human beings and the need for more studies and research. In particular, future studies are needed that address long-term effects and the effects of the combinations of elements which provide comfort or discomfort.Keywords: Comfort, discomfort, transportation, office design, expectations The influence of the environment on the human in a modelAccording to the Environmental Design Technical Group (EDTG) of the Human Factors and Ergonomics Society [1], "Environmental design is the discipline concerned with the relationship between human behavior and the designed environment". This special issue of WORK consists of 21 papers concerned with research in the area of environmental design. These papers studied environment and many designed environments for improvement of performance, well-being, comfort or experience * Address for correspondence: Conne Bazley, 5966 County- of humans in contact with the environment. The relationship with the human and the environment is schematically shown in Fig. 1. The scheme shows the environment, the human sensor noticing the environment, the brain processing the input, and the behavior. The process may commence as follows: the human brain decides to focus on a sense organ. These sense organs record a signal, which is processed by the brain. During this processing between the senses and the brain, experiences and the human state play a role. The human state can be excited or relaxed, which influences the way the input is processed. This process has an influence on the behavior of the human being. Time is an important factor. Sometimes the process starts with seeing the environment, which leads to the brain taking an action. Sometimes the brain activates sensors searching for an object such as an exit door. Time is also of importance as usually this action fits into a 'customer 1051-9815/16/$35.00
