“…De Looze et al [5] identified a variety of objective measures for comfort or discomfort from literature in medicine and ergonomics and concluded that pressure distribution showed the most clear association with the subjective ratings. Similar findings have also been shown in many other studies [15,16,17,18,19].…”

The design of functional seating furniture is a complicated process which often requires extensive manual design effort and empirical evaluation. We propose a computational design framework for pose-driven automated generation of body-supports which are optimized for comfort of sitting. Given a human body in a specified pose as input, our method computes an approximate pressure distribution that also takes frictional forces and body torques into consideration which serves as an objective measure of comfort. Utilizing this information to find out where the body needs to be supported in order to maintain comfort of sitting, our algorithm can create a supporting mesh suited for a person in that specific pose. This is done in an automated fitting process, using a template model capable of supporting a large variety of sitting poses. The results can be used directly or can be considered as a starting point for further interactive design.

“…Scientific evidence has determined that the mattresses comfort perception and their mechanical properties analyzed subjectively by users-mainly the elderly-is not sufficiently precise as to recommend customers to simply choose their future mattress through test in store (López-Torres et al 2008); a predictive model could probably facilitate the sleep system choice with a greater scientific basis.…”

This paper presents a novel system for automatic sleep system recommendation using RGB, depth and pressure information. It consists of a validated clinical knowledge-based model that, along with a set of prescription variables extracted automatically, obtains a personalized bed design recommendation. The automatic process starts by performing multi-part human body RGB-D segmentation combining GrabCut, 3D Shape Context descriptor and Thin Plate Splines, to then extract a set of anthropometric landmark points by applying orthogonal plates to the segmented human body. The extracted variables are introduced to the computerized clinical model to calculate body circumferences, weight, morphotype and Body Mass Index categorization. Furthermore, pressure image analysis is performed to extract pressure values and at-risk points, which are also introduced to the model to eventually obtain the final prescription of mattress, topper, and pillow. We validate the complete system in a set of 200 subjects, showing accurate category classification and high correlation results with respect to manual measures.

“…17,18 However, if the mattress is not suited for the person, pressure sores may develop at body regions where the pressure is concentrated. 19 The regions affected by higher pressure often include the buttocks, shoulder, and back, 17,20 which may consequently affect the quality of sleep and result in lethargy or body stiffness throughout the day. 21 A recent study by Bae and Ko 22 compared the bed positions of hospital mattresses and found that the head-foot angle of 30°was the best position to mitigate the possibility of decubitus ulcers occurring in patients at the high-pressure-risk regions.…”

“…20,23 A biomechanical comparison of these mattresses across different sleeping postures will allow us to provide new insights into their pressure-distributing capabilities. Therefore, the objective of this study was to evaluate the effect of different types of bed material (latex and polyurethane foam) on the body contact pressure profiles in various sleeping postures, using peak body pressure and pressure distribution as outcome measures.…”

Objectives: This study compared the body contact pressure profiles of 2 types of mattresses: latex and polyurethane. Methods: Twenty participants were required to lie down on the different mattresses in 3 different postures for 6 minutes, and their body contact pressure profiles were recorded with a pressure mat sensor. Results: The data indicated that the latex mattress was able to reduce the peak body pressure on the torso and buttocks and achieve a higher proportion of low-pressure regions compared with the polyurethane mattress. Conclusions: Latex mattress reduced peak body pressure and achieved a more even distribution of pressure compared with polyurethane mattress across different sleeping postures.
