Point and Listen: Augmented Reality Interfaces for the Visually Impaired

点和听：增强现实界面的视觉 受损 总结 CamIO（“相机输入输出”）是一个项目，旨在使物理对象，包括文件， 地图和3D对象，如建筑模型，盲人或视力正常的人完全可以使用 受损它通过基于音频的增强现实（AR）使这些对象可访问 界面：用户指向感兴趣的对象上的特定位置并听到音频信息 关于该位置的信息被大声读出（或者如果用户具有低的 视觉）。与其他使盲人或盲人能够接触到物体的方法相比， 视觉受损，CamIO提供了几个优点：（a）不需要修改或增加现有的 对象（例如，带有盲文标签或特殊的触摸感应按钮），只需要一部智能手机， 可选的可穿戴摄像设备;（B）CamIO即使对那些不流利的盲文也是可访问的 阅读器;以及（c）它允许用所有手指自然地探索对象，以实现听觉-触觉 与物体的相互作用。 基于我们过去在原型CamIO iPhone应用程序上的工作，我们计划开发功能强大的 增强功能和新功能，包括手指跟踪作为使用指向 手写笔，并支持可穿戴选项，如相机功能的设想眼镜，将提供一个 远比独立的智能手机应用程序更上级的用户界面。 功能将使盲人和视力受损的用户以及视力正常的助手能够轻松创建音频 对象的标签。我们还将深入探讨CamIO的两个令人兴奋的应用： 使触觉地图充分互动和更容易理解，并发展互动 设施，如大型游乐场的3D比例模型，帮助视障人士游乐场 让参观者熟悉游乐场的布局及特色。最后，失明的人 或视力受损者-CamIO系统的目标用户-将参与 建议的研究，以最大限度地发挥研究工作的影响。

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.
