As a hyper-natural interaction technique in 3D user interfaces, non-isomorphic rotation has been considered an effective approach for rotation tasks, where a static or dynamic control-display gain can be applied to amplify or attenuate a rotation. However, it is not clear whether non-isomorphic rotation can benefit 6-degree-of-freedom (6-DOF) manipulation tasks in AR and VR. In this article, we extended the usability studies of non-isomorphic rotation from rotation-only tasks to 6-DOF manipulation tasks and analyzed the collected data using a 2-component model. Using a mixed reality (MR) simulation approach, we also investigated whether environment (AR or VR) had an impact on 3D manipulation tasks. The results reveal that although both static and dynamic non-isomorphic rotation techniques could save time and effort in ballistic phases, only dynamic non-isomorphic rotation was significantly faster than isomorphic rotation. Interestingly, while environment had no significant impact on overall user performance, we found evidence that it could affect fine-tuning in correction phases. We also found that most participants preferred AR over VR, indicating that environmental visual realism could be helpful to improve user experience.

在混合现实模拟中评估非同构旋转对 3D 操作任务的影响

作为 3D 用户界面中的一种超自然交互技术,非同构旋转已被认为是旋转任务的有效方法,其中可以应用静态或动态控制显示增益来放大或减弱旋转。然而,目前尚不清楚非同构旋转是否有益于 AR 和 VR 中的 6 自由度 (6-DOF) 操作任务。在本文中,我们将非同构旋转的可用性研究从仅旋转任务扩展到 6 自由度操作任务,并使用 2 分量模型分析了收集的数据。使用混合现实 (MR) 模拟方法,我们还调查了环境(AR 或 VR)是否对 3D 操作任务产生影响。结果表明,虽然静态和动态非同构旋转技术都可以在弹道阶段节省时间和精力,只有动态非同构旋转明显快于同构旋转。有趣的是,虽然环境对整体用户性能没有显着影响,但我们发现有证据表明它可能会影响校正阶段的微调。我们还发现,大多数参与者更喜欢 AR 而不是 VR,这表明环境视觉真实感可能有助于改善用户体验。
