Remote sighted assistance (RSA) offers prosthetic support to people with visual impairments (PVI) through image- or video-based conversations with remote sighted assistants. While useful, RSA services introduce privacy concerns, as PVI may reveal private visual content inadvertently. Solutions have emerged to address these concerns on image-based asynchronous RSA, but exploration into solutions for video-based synchronous RSA remains limited. In this study, we developed , a high-fidelity prototype allowing PVI to conceal objects beyond a certain distance during RSA, granting them privacy control. Through an exploratory field study with 24 participants, we found that 22 appreciated the privacy enhancements offered by BubbleCam. The users gained autonomy, reducing embarrassment by concealing private items, messy areas, or bystanders, while assistants could avoid irrelevant content. Importantly, BubbleCam maintained RSA's primary function without compromising privacy. Our study highlighted a cooperative approach to privacy preservation, transitioning the traditionally individual task of maintaining privacy into an interactive, engaging privacy-preserving experience.
远程视力辅助(RSA)通过与远程有视力的助手进行基于图像或视频的对话,为视力障碍者(PVI)提供假肢支持。虽然RSA服务很有用,但也引发了隐私问题,因为视力障碍者可能会无意中泄露私人视觉内容。针对基于图像的异步RSA,已经出现了解决这些问题的方案,但对于基于视频的同步RSA的解决方案的探索仍然有限。在本研究中,我们开发了BubbleCam,这是一个高保真原型,允许视力障碍者在RSA期间隐藏一定距离之外的物体,从而给予他们隐私控制权。通过对24名参与者进行的探索性实地研究,我们发现22人赞赏BubbleCam提供的隐私增强功能。用户获得了自主权,通过隐藏私人物品、凌乱区域或旁观者来减少尴尬,而助手则可以避免无关内容。重要的是,BubbleCam在不损害隐私的情况下维持了RSA的主要功能。我们的研究强调了一种合作的隐私保护方法,将传统上维护隐私的个人任务转变为一种互动、引人入胜的隐私保护体验。
