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.

功能座椅家具的设计是一个复杂的过程，通常需要大量的手动设计工作和经验评估。我们提出了一种用于姿势驱动自动生成身体支撑的计算设计框架，该结构针对坐姿舒适性进行了优化。给定人体在指定姿势下的输入，我们的方法将计算近似压力分布，该分布还将摩擦力和身体扭矩纳入考虑范围，以此作为舒适度的客观指标。利用此信息找出需要支撑身体以保持舒适坐姿的位置，我们的算法可以创建适合该特定姿势的人的支撑网格。使用能够支持多种坐姿的模板模型，通过自动拟合过程完成此操作。
