在基于机器视觉手势交互中经常需要大幅度手部移动，合适的映射关系对于用户在较舒适的操作范围内完成交互任务是十分必要的． 文中结合用户的交互心理测试，提出一种基于用户操作特点的映射关系自适应调整方法: 基于Borg's CR-10 尺度心理感知实验测试用户的手部移动的感知，根据人体工程学建立一种基于速度调整的映射方程; 根据交互过程中的用户手部移动情况，在每次连续交互操作结束后对映射方程进行调整．此外利用Kinect 搭建用户测试系统测试该调整方法性能． 实验结果表明，文中提出的映射关系调整方法能有效降低用户大幅度手部移动的几率，同时保持了用户的操作表现．

As large amplitude hand movements are often involved in the machine vision-based gesture interaction,aproper control-display mapping relationship is necessary for users to complete interaction tasks in a comfortablemotion range.In this paper,an adaptive adjustment method of the control-display mapping relationship is proposedaccording to user's interaction features based on a psychological experiment.A Borg's CR-10 scale experiment isemployed to test user's perception of the hand movement velocity,and a mapping equation based on a velocityorientedtechnique is revised according to ergonomics.Then,according to user's hand movement amplitude,themapping equation is adjusted after each continuous interaction.Moreover,a user test system based on Kinect isestablished to test the performance of the proposed method.The results show that the proposed method can not onlyreduce the probability of large amplitude hand movements occurring but also keep user's performance stable.
