我们提出了一种新颖的触觉和音频反馈装置,允许盲人和视障(BVI)用户理解电路图。tangiblcircuits允许用户与3D打印的有形电路模型进行交互,该电路模型在触摸时提供音频教程方向。我们的系统包括一个自动解析算法,可以从Fritzing图中提取3D打印模型以及音频接口。为了更好地理解设计技术的需求,以帮助BVI用户学习硬件计算,我们对当前电路教程技术的可访问性局限性进行了一系列形成性调查。此外,我们从进行正式的比较用户研究中获得见解和设计考虑,以了解有形电路作为教程系统的有效性。我们发现英属维尔京群岛用户能够更好地理解几何,空间和结构电路信息使用有形电路,并享受与我们的工具学习。
We present a novel haptic and audio feedback device that allows blind and visually impaired (BVI) users to understand circuit diagrams. TangibleCircuits allows users to interact with a 3D printed tangible model of a circuit which provides audio tutorial directions while being touched. Our system comprises an automated parsing algorithm which extracts 3D printable models as well as an audio interfaces from a Fritzing diagram. To better understand the requirements of designing technology to assist BVI users in learning hardware computing, we conducted a series of formative inquiries into the accessibility limitations of current circuit tutorial technologies. In addition, we derived insights and design considerations gleaned from conducting a formal comparative user study to understand the effectiveness of TangibleCircuits as a tutorial system. We found that BVI users were better able to understand the geometric, spatial and structural circuit information using TangibleCircuits, as well as enjoyed learning with our tool.
