AI中文摘要：
传统VR视口控制主要依赖头部和躯干运动，在受限环境及长时间使用场景中均费力且受限。我们提出Looking Around by Looking Around（LALA），一种基于凝视的VR俯仰与偏航视口控制技术，旨在通过眼球运动实现自然且省力的全向探索，无需或不阻碍头部、手部或身体的运动，提供低 effort（省力）且高度可及的交互方法。由于凝视主要用于感知，且存在动眼和感知不对称性，直接将其用于控制较为困难。为解决这一问题，我们设计了一种针对眼睛的不对称全向控制轮廓，并在此基础上利用眼睛倾向于停留在舒适区域的特性进行视口控制。我们在包含18名参与者的用户研究中对LALA进行评估，研究设置了两个对比任务：朝向已知方向的对齐任务和朝向未知方向的开放式视觉搜索任务。与传统基线方法相比，LALA获得了强烈偏好，在实现完全免手持交互且身体运动极少的同时，达到了具有竞争力的性能。
英文摘要：
Traditional VR viewport control primarily relies on head and torso movement, which can be effortful and limiting in both constrained and extended-use settings. We introduce Looking Around by Looking Around (LALA), a gaze-based VR pitch-and-yaw viewport control technique designed for natural and effortless omnidirectional exploration via eye movements, without requiring or obstructing movement of the head, hand, or body, offering a low-effort and highly accessible interaction method. Because gaze is primarily used for perception and exhibits oculomotor and perceptual asymmetries, using it directly for control is difficult. To address this, we designed an asymmetric omnidirectional control profile for the eye, then built on it to exploit tendencies for eyes to stay within comfortable regions for viewport control. We evaluated LALA in a user study (N=18) featuring two contrasting tasks: alignment towards known directions and open-ended visual search towards unknown directions. LALA was strongly preferred over the traditional baseline, achieving competitive performance while enabling fully hands-free interaction with minimal physical movement.
