Abstract

Reaching surrounding target objects is difficult for blind and low-vision (BLV) users, affecting their daily life. Based on interviews and exchanges, we propose an unobtrusive wearable system called LiSee to provide BLV users with all-day assistance. Following a user-centered design method, we carefully designed the LiSee prototype, which integrates various electronic components and is disguised as a neckband headphone such that it is an extension of the existing headphone. The top-level software includes a series of seamless image processing algorithms to solve the challenges brought by the unconstrained wearable form so as to ensure excellent real-time performance. Moreover, users are provided with a personalized guidance scheme so that they can use LiSee quickly based on their personal expertise. Finally, a system evaluation and a user study were completed in the laboratory and participants’ homes. The results show that LiSee works robustly, indicating that it can meet the daily needs of most participants to reach surrounding objects.

LiSee:一款全天帮助盲人和低视力用户接触周围物体的耳机

盲人和低视力(BLV)用户很难到达周围的目标物体，影响了他们的日常生活。通过采访和交流，我们提出了一个不起眼的可穿戴系统LiSee，为BLV用户提供全天候的帮助。遵循以用户为中心的设计方法，我们精心设计了LiSee原型，它集成了各种电子元件，伪装成领口耳机，是现有耳机的延伸。顶层软件包含一系列无缝图像处理算法，解决不受约束的可穿戴形式带来的挑战，确保卓越的实时性。此外，还为用户提供了个性化的指导方案，使用户能够根据自己的专业知识快速使用LiSee。最后，在实验室和参与者家中完成了系统评估和用户研究。结果表明，LiSee工作稳健，表明它可以满足大多数参与者接触周围物体的日常需求。
