Design of and subjective response to on-body input for people with visual impairments
"To investigate preferences for and design of accessible on-body interaction, we conducted a study with 12 visually impaired participants. Participants evaluated five locations for on-body input and compared on-phone to on-hand interaction with one versus two hands. Our findings show that the least preferred areas were the face/neck and the forearm, while locations on the hands were considered to be more discreet and natural. The findings also suggest that participants may prioritize social acceptability over ease of use and physical comfort when assessing the feasibility of input at different locations of the body. Finally, tradeoffs were seen in preferences for touchscreen versus on-body input, with on-body input considered useful for contexts where one hand is busy (e.g., holding a cane or dog leash). We provide implications for the design of accessible on-body input."
Verification of daily activities of older adults: a simple, non-intrusive, low-cost approach
"This paper presents an approach to verifying the activities of daily living of older adults at their home. We verify activities, instead of inferring them, because our monitoring approach is driven by routines, initially sketched by users in their environment. Monitoring is supported by a lightweight sensor infrastructure, comprising non-intrusive, low-cost, wireless devices. Verification is performed by applying a simple formula to sensor log data, for each activity of interest. The result value determines whether an activity has been performed...Four participants have been monitored during five days at their home, equipped with sensors. When applied to the log data, our formulas were able to automatically verify that a list of activities were performed. They produced the same interpretations, using Signal Detection Theory, as a third party, manually analyzing the log data."

Mobile technology in inclusive research: tools of empowerment
"Inclusive research is an accepted approach when conducting research about individuals with disabilities. No studies have been published to date on using mobile technology to support people with intellectual disabilities as researchers. An inclusive research team of researchers with intellectual disabilities and academic researchers used mobile technology to support research skill acquisition. They conducted 15 joint research training sessions, followed by 10 research meetings. In order to discuss the experience of using iPads to support researchers with intellectual disabilities, the authors used a multiple-case study approach. Findings included the challenges and successes of mobile technology implementation. In conclusion, the iPads enhanced participation opportunities for the researchers with intellectual disabilities not only in the research, but also in other areas of their lives."
Enabling user interface developers to experience accessibility limitations through visual, hearing, physical, and cognitive impairment simulation
"This paper presents a tool facilitating developers of user interfaces (UIs) to experience accessibility limitations that can be posed from various disabilities during the interaction of impaired users with their developments. In this respect, various aspects of visual, hearing, physical and cognitive impairments have been modeled through filters providing approximate, yet, realistic simulations over them. These filters have formed the basis for the developed tool, which can be used either on its own (as a standalone application), or be embedded in the Net Beans Integrted Development Environment. The tool, named DIAS, allows for impairment simulations to be performed over Java, mobile and web applications. Moreover, it integrates two of the most common assistive technologies (ATs), namely a screen reader and a magnifier. As a result, developers of UIs can not only experience how interaction would be affected from various impairments, but they can also understand how their developments would be perceived by impaired users through an AT. This work aims to provide an integrated, practical solution for impairment simulation, which could be easily adopted by developers, thus realistically increasing the possibilities for the future development of interactive applications that are more accessible to users with disabilities."
