Abstract

Immersive virtual environments (IVEs) have been extensively investigated for applications in education and man-power training because of the benefits of immersion-driven experiences as immersion becomes a factor that can both accelerate and hamper learning depending on the user's area of focus, which supports the importance of engagement. In this paper, two fundamental approaches to visual engagement in IVE are compared: discipline and guidance. The approaches aim to foster the learner's engagement to predefined area to be focused by either subtracting visual stimuli (discipline) or appending visual indicators pointing to the area (guidance). The experimental results showed no significant improvement in memory recall accuracy and time. However, the guidance group showed superior performances in usability metrics. Interestingly, a significant difference was found in the objective measure of the participants' gaze pattern revealing that the discipline makes the user's gaze consistent and stable.

摘要

沉浸式虚拟环境（IVEs）因其沉浸式驱动体验的优势，已在教育和人力培训领域得到广泛研究。由于沉浸感成为一个既能加速学习又可能阻碍学习的因素，这取决于用户的关注领域，这也支持了参与度的重要性。本文比较了IVE中视觉参与的两种基本方法：约束和引导。这两种方法旨在通过减去视觉刺激（约束）或附加指向该区域的视觉指标（引导），促进学习者对预定义关注区域的参与。实验结果表明，在记忆回忆准确性和时间方面没有显著改善。然而，引导组在可用性指标方面表现更优。有趣的是，在参与者注视模式的客观测量中发现了显著差异，表明约束使用户的注视更加一致和稳定。
