Abstract

As machine learning algorithms continue to improve, collecting training data becomes increasingly valuable. At the same time, increased focus on data collection may introduce compounding privacy concerns. Accessibility projects in particular may put vulnerable populations at risk, as disability status is sensitive, and collecting data from small populations limits anonymity. To help address privacy concerns while maintaining algorithmic performance on machine learning tasks, we propose privacy-enhancing distortions of training datasets. We explore this idea through the lens of sign language video collection, which is crucial for advancing sign language recognition and translation. We present a web study exploring signers' concerns in contributing to video corpora and their attitudes about using filters, and a computer vision experiment exploring sign language recognition performance with filtered data. Our results suggest that privacy concerns may exist in contributing to sign language corpora, that filters (especially expressive avatars and blurred faces) may impact willingness to participate, and that training on more filtered data may boost recognition accuracy in some cases.

7. Sign Language Recognition, Generation, and Translation: An Interdisciplinary Perspective.

Abstract

Developing successful sign language recognition, generation, and translation systems requires expertise in a wide range of fields, including computer vision, computer graphics, natural language processing, human-computer interaction, linguistics, and Deaf culture. Despite the need for deep interdisciplinary knowledge, existing research occurs in separate disciplinary silos, and tackles separate portions of the sign language processing pipeline. This leads to three key questions: 1) What does an interdisciplinary view of the current landscape reveal? 2) What are the biggest challenges facing the field? and 3) What are the calls to action for people working in the field? To help answer these questions, we brought together a diverse group of experts for a two-day workshop. This paper presents the results of that interdisciplinary workshop, providing key background that is often overlooked by computer scientists, a review of the state-of-the-art, a set of pressing challenges, and a call to action for the research community.
