| Abstract | This study aims at evaluating and predicting the feasibility of electric care bed (ECB). Subjective evaluation were utilized to quantify the usage limitation of ECB and depict direction of shear in the passive motion process, Two groups of people were asked to finish a series of experiments on two types of electric care beds. The results were utilized in a virtual man-bed system to assess the influences of posture, motion process and figure. In each posture, the model was divided into 25 closed parts to calculate gravity of body parts in all given postures in repeated circulation process. With pressure measured by pressure mapping and shear direction known, the force distribution in dynamic system can be estimated. Conclusions are drawn from results of both subjective evaluation and force distribution simulation. A series of recommendations are given to improve passive motion of bed boards basing on the conclusions. The simulation method can also be used to quantify complex force distribution and predict the feasibility of unprecedented functions or new postures provided by mechanical assistance to some extend. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
