|a In virtual reality applications, in addition to visual feedback, real objects can be used as props for virtual objects to provide passive haptic feedback, which greatly enhances user immersion. Usually, real object props are not one-to-one correspondence with virtual objects. Haptic retargeting technique is proposed to establish the virtual-real correspondence by introducing an offset between the virtual hand and the real hand. Sometimes, the offset is too large to cause user discomfort, and it is necessary to introduce a reset between two haptic retargeting operations to force the virtual hand and the real hand to coincide in order to eliminate the offset. However, too many resets can interfere with this immersion. To address this problem, we propose a haptic retargeting method based on proxy importance calculation using multiple props in virtual reality. The concept of proxy importance for props is introduced first, and then a proxy importance based prop selection and placement method for moving virtual objects are proposed. We also improve the performance of our method by using the props' weighted proxy importance strategy for multi-user collaboration. Compared to the state-of-the-art methods, our method significantly reduces the number of resets, the task completion time, hand movement distances, and task load without the cost of cybersickness in the single-user task. In the multi-user collaborative task, our method also achieves significant improvement using the strategy that weights the proxy importance of the props
