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.

点与听：视觉上增强现实接口 受损 概括 Camio（“相机输入输出”）是一个旨在制作物理对象的项目，包括文档， 地图和3D对象，例如建筑模型，盲人或视觉上的人完全可以访问 受损。它使这些对象通过基于音频的增强现实（AR）访问 接口：用户指向感兴趣的对象的特定位置，并听到音频信息 关于此位置大声朗读（如果用户较低，则可以看到所选位置的增强图像 视觉）。 视力障碍，Camio提供了几个优点：（a）无需修改或增强现有 对象（例如，带有盲文标签或特殊触摸敏感按钮），仅需要智能手机和 可选的可穿戴相机设备； （b）即使对于那些不流利的盲文的人也可以访问Camio 读者； （c）它允许用所有手指自然探索物体，以启用音频 与对象的交互。 在我们过去在原型Camio iPhone应用程序上的工作的基础上，我们计划开发功能强大 增强功能和新功能，包括手指跟踪作为指向使用的替代 手写笔，并支持可穿戴选项，例如启用相机的设想眼镜，这些眼镜将提供 独立的智能手机应用程序可以使用的用户界面非常出色。新的创作 功能将使盲人和视觉障碍用户和视力障碍者变得容易创建音频 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 使触觉图完全互动且易于理解，以及互动的发展 大型游乐场的3D比例模型等装置，该模型有助于视觉上的操场 游客熟悉操场的布局和功能。最后，盲人的人 或视力障碍 - 相机系统的目标用户 - 将参与 拟议的研究，以最大程度地提高研究工作的影响。
