Chang, S.W. (author), Delleman, N.J. (author), Wang, M.J.J. (author), TNO Defensie en Veiligheid (author)The strategy for approaching a manual work position is an important reference for describing a goal-directed task. However, knowledge on this aspect of human behavior is scarce. The objectives of this study are twofold: (1) to describe and understand the strategy people tend to adopt for approaching a manual work position from different...article 2010

TNO Defensie en Veiligheid (author), Jansen, S.E.M. (author), Toet, A. (author), Delleman, N.J. (author)It is known that Field-of-view restrictions affect distance estimation, postural equilibrium, and the ability to control heading. These are all important factors when manoeuvring on foot through complex structured environments. Although considerable research has been devoted to the horizontal angular extent of the Field-of-View (FoV), rather...article 2010

Koerhuis, C.L. (author), Veenstra, B.J. (author), van Dijk, J.J. (author), Delleman, N.J. (author), TNO Defensie en Veiligheid (author)The objective of this study was to establish the best prediction for endurance time of combat soldiers marching with extremely heavy loads. It was hypothesized that loads relative to individual characteristics (% maximal load carry capacity [MLCC], % body mass, % lean body mass) would better predict endurance time than load itself. Twenty-three...article 2009

Toet, A. (author), Kahrimanović, M. (author), Delleman, N.J. (author), TNO Defensie en Veiligheid (author)Restrictions of field-of-view are known to impair human performance for a range of different tasks. However, such effects on human locomotion through a complex environment are still not clear. Effects of both horizontal (30°, 75°, 112°, 120°, 140°, 160°, and 180°) and vertical (18° and 48°) field-of-view restrictions on the walking speed and...article 2008

Jansen, S.E.M. (author), Toet, A. (author), Delleman, N.J. (author), TNO Defensie en Veiligheid (author), Nato (author)Field-of-view (FOV) restrictions are known to affect human behaviour and to degrade performance for a range of different tasks. A proposed cause for this performance impairment is the predominant activation of the ventral cortical stream as compared to the dorsal stream. This may compromise the ability to control heading as well as degrade the...conference paper 2008

(author)This paper reports 2 baseline studies and 1 experiment performed in a confined-space military vehicle concerning the effects on fitness and performance of time in a sitting posture and workstation characteristics. On average physical fitness decreased by slightly more than 10% per hour, the observation performance decreased by ~30% per hour, and...article 2008

Chang, S.W. (author), Wang, M.J. (author), Delleman, N.J. (author), TNO Defensie en Veiligheid (author)In general manufacturing consists of a sequence of actions on different spots. Depending on the sequence, workers may have to approach a spot from varying angles. The purpose of the study conducted was to describe the whole-body orientation and position when approaching a spot for a manufacturing action from five different angles, starting...conference paper 2007

Delleman, N.J. (author), Hin, A.J.S. (author), Tan, T.K. (author), TNO Technische Menskunde (author)This paper describes postural behaviour in static reaching sidewards, and the role of the trunk in particular. It turned out that the trunk (chest, pelvis) is not involved when reaching sidewards up to roughly 40-50°(depending on the reach distance). At greater angles the arm, the chest, and the pelvis each contribute at a particular rate to get...conference paper 2003
