  • Human-Bed Interaction: A Methodology and Tool to Measure Postural Behavior during Sleep of the Air Force Military
    Publication . Desouzart, Gustavo; Vilar, Ernesto Filgueiras; Melo, Filipe; Matos, Rui
    The behavioral and postural habits and sleep rhythm of air force military change depending on the specialty work at the airbase or other types of events but we did not find anything in the literature to analyze and evaluate this behavior through sleep disorders. Perhaps this is related to the fact that the evaluation of this behavior is complex and the observation of these postural behaviors in the environmental context is needed. However the observation methodology based on ISEE software [9] allows the classification and registration of postural behaviors for long periods of time and can be applied in this context. This paper presents a study whose objective was to research the human interaction with postural behaviors during sleep in the residences' bedrooms of male air force military during the periods in which the subjects were asleep, awake, out of bed, doing activities, using a pillow in different time periods and with ecological validation with observation method and Visual Analogical Scale (VAS). A sample of 8666 observations, which corresponds to 240 sleep-hours of 12 air force military, was classified into six (6) Interaction Categories (IC). The results show that 50,2% of the participants presented the Lateral position (25,38% on the left and 24,86% on the right) as the most common postural behavior during sleep and 94,1% used only one pillow under their head. In the IĆs, the most common interactions were sleep period using the pillow with 66,47%, followed by category Out of bed with 25,32% and followed the category the activities and using the pillow with 6,95%. Findings of this study allow suggesting what graphical interface designers must seek as new strategies and solutions for behavior change in posture in bed, exploring other peripheral equipment for sleep position; or, at least, to improve the posture of the participants when using the number and the placement of the pillow in bed and if these Ergonomic changes can influence the reduction in back pain indications.
