Point and Listen: Augmented Reality Interfaces for the Visually Impaired Summary CamIO (“Camera Input-Output”) is a project designed to make physical objects, including documents, maps and 3D objects such as architectural models, fully accessible to people who are blind or visually impaired. It makes these objects accessible by means of an audio-based Augmented Reality (AR) interface: the user points to a specific location on an object of interest and hears audio information about this location read aloud (or sees an enhanced image of the selected location if the user has low vision). Compared with other approaches to making objects accessible to people who are blind or visually impaired, CamIO offers several advantages: (a) there is no need to modify or augment existing objects (e.g., with braille labels or special touch-sensitive buttons), requiring only a smartphone and optional wearable camera device; (b) CamIO is accessible even to those who are not fluent braille readers; and (c) it permits natural exploration of the object with all fingers to enable audio-haptic interactions with the object. Building on our past work on the prototype CamIO iPhone app, we plan to develop powerful enhancements and new functionality, including finger tracking as an alternative to the use of a pointing stylus, and support for wearable options such as the camera-enabled Envision Glasses that will offer a far superior user interface to what is possible with a stand-alone smartphone app. New authoring capabilities will make it easy for blind and visually impaired users and sighted assistants to create audio labels for objects. We will also pursue two exciting applications of CamIO in depth: using CamIO to make tactile maps fully interactive and easier to understand, and the development of interactive installations such as a 3D scale model of a large playground that helps visually impaired playground visitors familiarize themselves with the playground’s layout and features. Finally, people who are blind or visually impaired – the target users of the CamIO system – will be involved in all aspects of the proposed research, to maximize the impact of the research effort.

指向和倾听：为视觉用户提供增强现实界面 受损的 摘要 CamIO(“相机输入-输出”)是一个旨在制作实物的项目，包括文档， 地图和3D对象，如建筑模型，盲人或视障人士完全可以访问 受伤了。它通过基于音频的增强现实(AR)来访问这些对象 界面：用户指向感兴趣对象上的特定位置并听到音频信息 有关此位置的信息请大声阅读(或查看所选位置的增强图像，如果用户具有 愿景)。与其他使盲人或盲人可以接近物品的方法相比 CamIO具有以下几个优点：(A)不需要修改或扩充现有的 对象(例如，带有盲文标签或特殊触敏按钮)，仅需要智能手机和 可选的可穿戴式摄像设备；(B)CamIO即使不是流利的盲文也可以使用 阅读器；以及(C)它允许用所有手指对物体进行自然探索，以实现音频触觉 与对象的交互。 基于我们过去在CamIO iPhone原型应用程序上的工作，我们计划开发功能强大的 增强和新功能，包括作为使用指点的替代方案的手指跟踪 手写笔，以及对可穿戴选项的支持，例如支持相机的enVision眼镜，它将提供 与独立的智能手机应用程序相比，用户界面要优越得多。新创作 这些功能将使盲人和视障用户以及有视力的助理能够轻松地创建音频 对象的标签。我们还将深入探讨CamIO的两个令人兴奋的应用：使用CamIO 使触觉地图具有充分的互动性和易读性，并发展了互动性 装置，如大型游乐场的3D比例模型，帮助视障人士 参观者熟悉游乐场的布局和特点。最后，盲人 或视障人士--CamIO系统的目标用户--将参与 提出研究建议，以最大限度地发挥研究成果的影响力。
