群体控制理论显示出控制多个对象的前景，然而，其可扩展性受到成本的限制，例如硬件和基础设施需求。虚拟现实技术可以克服这些局限性，但对虚拟现实中群体交互的研究还很有限。本文介绍了一种新的群体操纵交互技术，并将其与虚拟手和控制器（光线投射）这两种基线技术进行了比较。我们在一项用户研究（N = 12）中评估了这些技术，涉及五种情况下的三个任务（选择、旋转和调整大小）。总体而言，我们的结果表明，在这三个任务的大多数条件下，群体操作技术确实产生了良好的性能，与其他两种技术中的至少一种相比，表现出明显更快的速度。此外，该技术显著减少了调整大小任务中的大小偏差。然而，我们也观察到在旋转任务中速度和准确性之间的权衡。结果表明，与传统操作技术相比，群体操作技术在增强VR中的可用性和用户体验方面具有潜力。在未来的研究中，我们的目标是理解和改进群体交互、用户控制和内部粒子合作。
The theory of swarm control shows promise for controlling multiple objects, however, its scalability is limited by costs, such as hardware and infrastructure needs. Virtual Reality (VR) can overcome these limitations, but research on swarm interaction in VR is limited. This paper introduces a novel Swarm Manipulation interaction technique and compares it with two baseline techniques: Virtual Hand and Controller (ray-casting). We evaluated these techniques in a user study (N = 12) in three tasks (selection, rotation, and resizing) across five conditions. Overall, our results show that the swarm manipulation technique did result in good performance, exhibiting significantly faster speeds compared with at least one of the other two techniques across most conditions for these three tasks. Furthermore, this technique notably reduced resizing size deviations in the resizing task. However, we also observed a trade-off between speed and accuracy in the rotation task. The results demonstrate the potential of the Swarm Manipulation technique to enhance the usability and user experience in VR compared to conventional manipulation techniques. In future studies, we aim to understand and improve swarm interaction, user control, and internal particle cooperation.
