Pressure and distortion imposed by automatic care beds can lead to negative effects during interaction process. Motion discrepancy between human body and care bed surface causes shear as another type of risks. While relationship between structure design and risk remains unclear. To quantify design limitation and predict the feasibility of Automatic Care Bed(ACB) in lateral turning over Tasks, a virtual man-bed system was established according to two types of structures. A mannequin was modified to simulate patients of different types of figure. Eighteen subjects (6 males and 12 females) were measured by a pressure mapping system for interaction data collection. Distortion, pressure and friction caused by motion discrepancies were quantified to assessed the negative effect of existing structures of care beds. Possibility of structure redesigned is recommended to reduce pressure and distortion. Some auxiliary structures are used to relieve shear and friction.
