Abstract

|
|
| This study explores how digital human models (DHMs) can be used to assess quality of spine support on bedding systems. A generic surface model has been developed that can be personalized based on a set of anthropometric input parameters. Shape assessment of the personalized surface models was performed by 3D surface scans of the trunk. Results showed a mean unsigned distance of 9.77 mm between modeled and scanned meshes. The surface model is combined with an inner skeleton model, allowing the model to adopt distinct sleep postures. Evaluation of spinal alignment is achieved by combining the personalized model with mattress indentation measurements. An automatic fitting algorithm sets the appropriate degrees of freedom to position the model on the measured indentation in the adopted sleep posture. Root mean square deviation between modeled and measured spine shape was 11.5 mm, indicating the usefulness of DHMs to increase efficiency in early stage bed design. |
