自由探索是许多引人入胜的虚拟现实（VR）体验的重要方面，但由于依赖视觉反馈，盲人和低视力（BLV）用户在很大程度上无法进行。现有方法通过预建的环境菜单和音频信标支持BLV导航，但对自由形式的发现支持有限。我们提出了VisionPulse，这是一个无障碍VR系统，使BLV用户能够通过自然的头部和手部动作，结合听觉、触觉和文本到语音反馈来探索虚拟环境。VisionPulse引入了一种发现驱动的方法，允许用户逐步发现区域和物体，同时通过航点引导和基于响应音频及基于方向的触觉进行物体定位来提供导航支持。对12名BLV参与者的研究表明，他们对VisionPulse基于发现的探索和多模态反馈有强烈偏好，且不影响任务性能或感知工作量。我们的发现强调了无障碍、自由形式VR体验的重要性，并为包容性VR设计提供了见解。
英文摘要
Free exploration is an important aspect of many engaging virtual reality (VR) experiences, yet remains largely inaccessible to blind and low vision (BLV) users due to its reliance on visual feedback. Existing approaches support BLV navigation through prebuilt menus of environment and audio beacons, but offer limited support for free-form discovery. We present VisionPulse, an accessible VR system that enables BLV users to explore virtual environments through natural head and hand movements, combined with auditory, haptic, and text-to-speech feedback. VisionPulse introduces a discovery-driven approach that allows users to progressively uncover regions and objects, alongside navigation support through waypoint guidance and object localization via responsive audio and orientation-based haptics. A study with 12 BLV participants showed a strong preference for VisionPulse's discovery-based exploration and multimodal feedback, without negatively impacting task performance or perceived workload. Our findings underscore the importance of accessible, free-form VR experiences, and contribute insights for inclusive VR design.
