变焦显示屏通过动态匹配焦点距离缓解视近冲突，提升增强现实系统中3D指针性能，但个体差异显著。
摘要：
本文研究了一种定制变焦显示屏是否能改善增强现实（AR）中的3D指针性能，其中视近冲突（VAC）已被知会损害交互。变焦显示屏被假设通过动态匹配焦点距离到用户目光定义的目标深度来缓解VAC。继先前工作之后，我们进行了24名参与者在变焦和固定焦点视图下完成ISO 9241-411指针任务的内受试研究。总体而言，变焦视图在关键交互指标上显著优于固定焦点基线，尽管收益的幅度甚至方向在个体之间有所不同。特别是，参与者的响应表现出基线依赖性模式，对于基线表现更好的参与者，观察到较小的改进（或偶尔的退化）。我们的发现表明，变焦技术可以相对于固定焦点视图改善AR指针性能，同时强调了应考虑的重大个体差异。
英文摘要：
This paper investigates whether a custom varifocal display can improve 3D pointing performance in augmented reality (AR), where the vergence-accommodation conflict (VAC) is known to impair interaction. Varifocal displays have been hypothesized to alleviate the VAC by dynamically matching the focal distance to the user's gaze-defined target depth. Following prior work, we conducted a within-subject study with 24 participants performing an ISO 9241-411 pointing task under varifocal and fixed-focal viewing. Overall, varifocal viewing yielded significantly higher performance than the fixed-focal baseline across key interaction metrics, although the magnitude and even the direction of the benefit varied across individuals. In particular, participants' responses exhibited a baseline-dependent pattern, with smaller improvements (or occasional degradation) observed for those with better baseline performance. Our findings suggest that varifocal technology can improve AR pointing performance relative to fixed-focal viewing, while highlighting substantial individual differences that should be considered in design and evaluation.
