Summary
This paper presents a two-method qualitative study examining how people with visual and motor disabilities select, adapt, and use mobile devices in their daily lives. The researchers interviewed 20 participants (ages 20-66) with visual disabilities (blindness, low vision) and motor impairments, then conducted a one-week diary study with 19 of them, collecting 85 diary entries about real-world mobile device use. Participants carried a total of 90 mobile devices at least once per week, including phones and smartphones (24), music players (12), laptops (11), GPS devices (2), as well as portable accessibility devices like canes (13), magnifiers (3), portable CCTVs (1), and Braille compasses (1). The study explored how participants researched and acquired devices, adapted to accessibility challenges on the go, accessed information while away from home, and what features they desired. Only six participants used mobile phones with built-in accessibility features, with cost being a major barrier — five participants cited expense as a reason for choosing commodity devices over specialized accessible ones. Thirteen participants had phones that did not allow installing additional applications like screen readers.
Key findings
The study revealed a rich landscape of adaptive strategies that people with disabilities employ to overcome mobile device accessibility barriers. Participants adapted physically — using wrist straps, hip holsters, magnifiers attached to phones, and unconventional holding positions. They adapted behaviorally — practicing at home with magnifiers to memorize button layouts, wearing headphones in only one ear to maintain situational awareness, and stopping movement entirely to use a phone. They used multiple devices strategically, carrying redundant devices for reliability and using different devices for complementary functions (e.g., storing phone numbers in an accessible note-taker to compensate for inaccessible phone address books). Environmental factors significantly affected use: crowded spaces, lighting conditions, weather, and walking all created additional barriers. The most desired features were screen readers (5 participants), voice input (5), larger buttons (4), and screen magnification (3). Participants expressed both positive and negative views about how mobile devices affected their independence — some found them empowering ("It's a whole different world for a blind person"), while others noted increased dependence on devices that could fail. The study also found that participants who used specialized accessible devices were sometimes reluctant to rely on them due to cost and the risk of manufacturers discontinuing products.
Relevance
Published in the early smartphone era (2009), this study captures a pivotal moment in mobile accessibility — before touchscreen smartphones with built-in accessibility features became ubiquitous. Many of the barriers documented (inability to install apps, lack of built-in screen readers, small physical buttons) have since been partially addressed by iOS VoiceOver and Android TalkBack, making the paper valuable as both a historical baseline and a demonstration of enduring design principles. The adaptive strategies participants developed — using multiple devices, memorizing interfaces, physically modifying hardware — highlight the creativity and resourcefulness of disabled users, which designers should support rather than work against. The finding that environmental factors (crowding, lighting, weather, walking) compound device accessibility problems remains highly relevant for mobile design. The study's guidelines — configurable interfaces, better text sizing, multimodal input/output, integrated assistive features in mainstream devices — have largely been validated by the direction the mobile industry has taken since publication.
