Personal navigation tools have greatly impacted the lives of people with vision impairments. As people with vision impairments often have different requirements for technology, it is important to understand users' ever-changing needs. We conducted a formative study exploring how people with vision impairments used technology to support navigation. Our(More)
Sighted people often have the best of intentions when they want to help a blind person navigate, but their well meaning is also often coupled with a lack of knowledge and understanding about how a person navigates without vision. As a result what sighted people think is the right feedback is too often the wrong feedback to give to a person with a visual(More)
We present SWARM, a wearable affective technology designed to help a user to reflect on their own emotional state, modify their affect, and interpret the emotional states of others. SWARM aims for a universal design (inclusive of people with various disabilities), with a focus on modular actuation components to accommodate users' sensory capabilities and(More)
In this paper we document two participatory design workshops conducted with a team of eight visually impaired adults that explored features and form factors for a wearable navigation technology. We compare and contrast our experiences conducting a low-fidelity prototyping activity using office supplies and a medium-fidelity prototyping activity using(More)
Many clothing characteristics (from garment color to care instructions) are inaccessible to people with vision impairments. To address this problem, clothing information is gathered from sighted companions, and later recalled using low-tech solutions such as adding safety pins to clothes. Unfortunately, these low-tech solutions require precise memory (such(More)
Large indoor spaces continue to pose challenges to independent navigation for people who are blind. Unfortunately, assistive technologies designed to support indoor navigation frequently make errors that are technically difficult or impossible to eliminate. We conducted a study to explore whether there are strategic ways designers can minimize the impact of(More)
The ability for one to navigate independently can be essential to maintaining employment, taking care of oneself, and leading a fulfilling life. However, for people who are blind, navigation-related tasks in public spaces--such as locating an empty seat--can be difficult without appropriate tools, training, or social context. We present a study of social(More)
