当盲人或视力受损的人浏览移动的网络时，他们必须随时拿着手机。在小屏幕上的这种连续的双手交互妨碍了用户保持双手空闲以控制辅助设备（例如，手杖）或触摸附近的物体，特别是在旅途中。在本文中，我们介绍了无屏幕访问：浏览方法，使用户能够交互触摸自由与听觉导航架构使用单手，在空中的手势识别的现成的臂章。在一项有10名盲人或视力受损者参与的研究中，我们观察到熟练的导航性能，用户与无屏幕范式的概念契合，以及低水平的认知负荷。我们的研究结果模拟了用户由于设计和系统的限制而犯下的错误，揭示了参与者使用的导航风格，并说明了有效地制定适当技术的手势的自发适应。用户反馈揭示了对无屏导航的潜力和局限性的见解，以支持旅行，工作环境和隐私保护场景的便利性，以及对可能成为社交显眼的手势的担忧。
When people who are blind or visually impaired navigate the mobile web, they have to hold a phone in their hands at all times. Such continuous, two-handed interaction on a small screen hampers the user's ability to keep hands free to control aiding devices (e.g., cane) or touch objects nearby, especially on-the-go. In this paper, we introduce screenless access: a browsing approach that enables users to interact touch-free with aural navigation architectures using one-handed, in-air gestures recognized by an off-the-shelf armband. In a study with ten participants who are blind or visually impaired, we observed proficient navigation performance, users conceptual fit with a screen-free paradigm, and low levels of cognitive load. Our findings model the errors users made due to limits of the design and system proposed, uncover navigation styles that participants used, and illustrate unprompted adaptations of gestures that were enacted effectively to appropriate the technology. User feedback revealed insights into the potential and limitations of screenless navigation to support convenience in traveling, work contexts and privacy-preserving scenarios, as well as concerns about gestures that may become socially conspicuous.
