Deploying VizLens: Characterizing User Needs, Preferences, and Challenges of Physical Interfaces Usage in the Wild
Andi Xu, Mahdi Qazwini, Chen Liang, Anhong Guo · 2023
Blind or Visually Impaired (BVI) people often encounter flat, inaccessible interfaces. Current solutions lack cost-effectiveness, portability, and robustness in real-world settings. We introduce VizLens, a fully-automated, full-stack mobile application powered by computer vision algorithms. The system is deployed and publicly available through the Apple App Store (https://vizlens.org/). From May to August 2023, we had 665 users, who uploaded 1,320 interface images. We aim to use it to study usage patterns and possible challenges BVI users may encounter with flat interfaces through a large-scale study in real-world settings. With in-depth analysis of user data and activity logs, our study will provide insights into BVI users’ interface interests, preferred assistance modes, and potential challenges due to system limitations or users’ diverse abilities. Our goal is to enhance the understanding of how BVI users interact with inaccessible, flat interfaces, and inform future assistive technology design.
