We describe a new approach to audio labeling of 3D objects such as appliances, 3D models and maps that enables a visually impaired person to audio label objects. Our approach to audio labeling is called CamIO, a smartphone app that issues audio labels when the user points to a (a location of interest on an object) with a handheld stylus viewed by the smartphone camera. The CamIO app allows a user to create a new hotspot location by pointing at the location with a second stylus and recording a personalized audio label for the hotspot. In contrast with other audio labeling approaches that require the object of interest to be constructed of special materials, 3D printed, or equipped with special sensors, CamIO works with virtually any rigid object and requires only a smartphone, a paper barcode pattern mounted to the object of interest, and two inexpensive styluses. Moreover, our approach allows a visually impaired user to create audio labels independently. We describe a co-design performed with six blind participants exploring how they label objects in their daily lives and a study with the participants demonstrating the feasibility of CamIO for providing accessible audio labeling.
我们描述了一种针对诸如电器、3D模型和地图等3D物体进行音频标注的新方法，该方法能让视障人士为物体添加音频标注。我们的音频标注方法名为CamIO，它是一款智能手机应用程序，当用户用手持触控笔指向智能手机摄像头所看到的物体上的一个热点（物体上的一个感兴趣位置）时，该应用程序会发出音频标注。CamIO应用程序允许用户通过用另一支触控笔指向某个位置并为该热点录制个性化音频标注来创建新的热点位置。与其他需要将感兴趣的物体由特殊材料制成、进行3D打印或配备特殊传感器的音频标注方法不同，CamIO几乎可以与任何刚性物体配合使用，并且只需要一部智能手机、一个粘贴在感兴趣物体上的纸质条形码图案以及两支廉价的触控笔。此外，我们的方法允许视障用户独立创建音频标注。我们描述了与六名盲人参与者进行的协同设计，探讨他们在日常生活中如何为物体添加标注，以及与参与者进行的一项研究，证明了CamIO提供无障碍音频标注的可行性。
