How Teens with Visual Impairments Take, Edit, and Share Photos on Social Media

論文アブストラクト: We contribute a qualitative investigation of how teens with visual impairments (VIP) access smartphone photography, from the time they take photos through editing and sharing them on social media. We observed that they largely want to engage with photos visually, similarly to their sighted peers, and have developed strategies around photo capture, editing, sharing, and consumption that attempt to mitigate usability limitations of current photography and social media apps. We demonstrate the need for more work examining how young people with low vision engage with smartphone photography and social media, as they are heavy users of such technologies and have challenges distinct from their totally blind counterparts. We conclude with design considerations to alleviate the usability barriers we uncovered and for making smartphone photography and social media more accessible and relevant for VIPs.

A Face Recognition Application for People with Visual Impairments: Understanding Use Beyond the Lab

論文アブストラクト: Recognizing others is a major challenge for people with visual impairments (VIPs) and can hinder engagement in social activities. We present Accessibility Bot, a research prototype bot on Facebook Messenger, that leverages state-of-the-art computer vision and a user's friends' tagged photos on Facebook to help people with visual impairments recognize their friends. Accessibility Bot provides users information about identity and facial expressions and attributes of friends captured by their phone's camera. To guide our design, we interviewed eight VIPs to understand their challenges and needs in social activities. After designing and implementing the bot, we conducted a diary study with six VIPs to study its use in everyday life. While most participants found the Bot helpful, their experience was undermined by perceived low recognition accuracy, difficulty aiming a camera, and lack of knowledge about the phone's status. We discuss these real-world challenges, identify suitable use cases for Accessibility Bot, and distill design implications for future face recognition applications.

Caption Crawler: Enabling Reusable Alternative Text Descriptions using Reverse Image Search

論文URL: http://dl.acm.org/citation.cfm?doid=3173574.3174092

論文アブストラクト: Accessing images online is often difficult for users with vision impairments. This population relies on text descriptions of images that vary based on website authors' accessibility practices. Where one author might provide a descriptive caption for an image, another might provide no caption for the same image, leading to inconsistent experiences. In this work, we present the Caption Crawler system, which uses reverse image search to find existing captions on the web and make them accessible to a user's screen reader. We report our system's performance on a set of 481 websites from alexa.com's list of most popular sites to estimate caption coverage and latency, and also report blind and sighted users' ratings of our system's output quality. Finally, we conducted a user study with fourteen screen reader users to examine how the system might be used for personal browsing.

Understanding the Accessibility of Smartphone Photography for People with Motor Impairments

論文URL: http://dl.acm.org/citation.cfm?doid=3173574.3174094

論文アブストラクト: We present the results of an exploration to understand the accessibility of smartphone photography for people with motor impairments. We surveyed forty-six people and interviewed twelve people about capturing, editing, and sharing photographs on smartphones. We found that people with motor impairments encounter many challenges with smartphone photography, resulting in users capturing fewer photographs than they would like. Participants described various strategies they used to overcome challenges in order to capture a quality photograph. We also found that photograph quality plays a large role in deciding which photographs users share and how often they share, with most participants rating their photographs as average or poor quality compared to photos shared on their social networks. Additionally, we created design probes of two novel photography interfaces and received feedback from our interview participants about their usefulness and functionality. Based on our findings, we propose design recommendations for how to improve the accessibility of mobile photoware for people with motor impairments.
