基于SLAM技术主动式定位的虚拟现实手控器产品交互设计

Interactive design of virtual reality hand controller based on SLAM technology

在虚拟现实中,三维交互设计技术对于提供沉浸式体验至关重要。手控器的位姿定位一直是一大难题。为此,研究采用同步定位与地图构建技术改进其定位性能,并引入了新颖的平稳策略。结果显示,在三维指向任务中,基于同步定位与地图构建的相机控制器平均耗时9.40 s,略高于HTC的9.10 s和Oculus的9.25 s。在三维放置和追踪任务中,相机控制器的表现与其他控制器相当或略有差异。值得注意的是,当不处理位姿跳变,与75%的可察觉阈值相比,5 cm的偏移被用户明显感知。但新策略显著降低了这种异常感知,提升了交互流畅性。可以发现,尽管存在某些挑战,基于同步定位与地图构建的手控器在大多数应用中都表现出色。该研究为提高虚拟现实的交互体验提供了新的思路。

In virtual reality,3D interaction design techniques are crucial to providing immersive experiences.The position and pose positioning of manual controller is always a big problem.Therefore,synchronous positioning and map construction techniques are used to improve its positioning performance,and a novel stationary strategy is introduced.The results showed that the camera controller built on synchronous positioning and mapping took an average of 9.40 seconds in 3D pointing tasks,slightly higher than HTC’s 9.10 seconds and Oculus’9.25 seconds.In 3D placement and tracking tasks,camera controllers perform equally or slightly differently than other controllers.It is worth noting that when the pose jump is not processed,the shift of 5cm is significantly perceived by the user compared to the perceptible threshold of 75%.However,the new strategy significantly reduces this abnormal perception and improves interaction fluency.It can be found that despite some challenges,the hand controller based on synchronous location and map construction performs well in most applications.This study provides a new way to improve the interactive experience of virtual reality.
