Sports are increasingly data-driven. Athletes use a variety of physical activity monitors to capture their movements, improve performance, and achieve excellence. To understand how wheelchair athletes want to use and share their activity data, we conducted a study using a prototype wheelchair fitness tracking device, which served as a probe to facilitate discussions. We interviewed 15 wheelchair basketball players about the use of performance data in the context of wheelchair basketball, and we discuss several implications for using and sharing automatically-tracked data. We find that the wheelchair basketball community is less concerned about the privacy of their data, and, in contrast to health data, athletes are motivated by competition. We conclude with a set of design opportunities that leverage digitized performance metrics within wheelchair basketball, which could apply to the broader wheelchair and adaptive athletics community.

The usage of smartphone-based virtual assistants (e.g., Siri or Google Assistant) is growing, and their spread has generally a positive impact on device accessibility, e.g., for people with disabilities. However, people with dysarthria or other speech impairments may be unable to use these virtual assistants with proficiency. This paper investigates to which extent people with ALS-induced dysarthria can be understood and get consistent answers by three widely used smartphone-based assistants, namely Siri, Google Assistant, and Cortana. We focus on the recognition of Italian dysarthric speech, to study the behavior of the virtual assistants with this specific population for which no relevant studies are available. We collected and recorded suitable speech samples from people with dysarthria in a dedicated center of the Molinette hospital, in Turin, Italy. Starting from those recordings, the differences between such assistants, in terms of speech recognition and consistency in answer, are investigated and discussed. Results highlight different performance among the virtual assistants. For speech recognition, Google Assistant is the most promising, with around 25% of word error rate per sentence. Consistency in answer, instead, sees Siri and Google Assistant provide coherent answers around 60% of times.

Walkability indices such as walkscore.com model the proximity and density of walkable destinations within a neighborhood. While these metrics have gained widespread use (e.g., incorporated into real-estate tools), they do not integrate accessibility-related features such as sidewalk conditions or curb ramps-thereby excluding a significant portion of the population. In this poster paper, we explore the initial design and implementation of neighborhood accessibility models and visualizations for people with mobility impairments. We are able to overcome previous data availability challenges by using the Project Sidewalk API, which provides access to 255,000+ labels about the accessibility and location of DC sidewalks.

Navigation assistive technologies aim to improve the mobility of blind or visually impaired people. In particular, turn-by-turn navigation assistants provide sequential instructions to enable autonomous guidance towards a destination. A problem frequently addressed in the literature is to obtain accurate position and orientation of the user during such guidance. An orthogonal challenge, often overlooked in the literature, is how precisely navigation instructions are followed by users. In particular, imprecisions in following rotation instructions lead to rotation errors that can significantly affect navigation. Indeed, a relatively small error during a turn is amplified by the following frontal movement and can lead the user towards incorrect or dangerous paths. In this contribution, we study rotation errors and their effect on turn-by-turn guidance for individuals with visual impairments. We analyze a dataset of indoor trajectories of 11 blind participants guided along three routes through a multi-story shopping mall using NavCog, a turn-by-turn smartphone navigation assistant. We find that participants extend rotations by 17º on average. The error is not proportional to the expected rotation; instead, it is accentuated for "slight turns" (22.5º-60º), while "ample turns" (60º-120º) are consistently approximated to 90º. We generalize our findings as design considerations for engineering navigation assistance in real-world scenarios.

Our research explores the potential of wearable Mixed Reality (MR) for people with Neuro-Developmental Disorders (NDD). The paper presents HoloLearn, a MR application designed in cooperation with NDD experts and implemented using HoloLens technology. The goal of HoloLearn is to help people with NDD learn how to perform simple everyday tasks in domestic environments and improve autonomy. An original feature of the system is the presence of a virtual assistant devoted to capture the user's attention and to give her/him hints during task execution in the MR environment. We performed an exploratory study involving 20 subjects with NDD to investigate the acceptability and usability of HoloLearn and its potential as a therapeutic tool. HoloLearn was well-accepted by the participants and the activities in the MR space were perceived as enjoyable, despite some usability problems associated to HoloLens interaction mechanism. More extensive and long term empirical research is needed to validate these early results, but our study suggests that HoloLearn could be adopted as a complement to more traditional interventions. Our work, and the lessons we learned, may help designers and developers of future MR applications devoted to people with NDD and to other people with similar needs.

Walking in environments with stairs and curbs is potentially dangerous for people with low vision. We sought to understand what challenges low vision people face and what strategies and tools they use when navigating such surface level changes. Using contextual inquiry, we interviewed and observed 14 low vision participants as they completed navigation tasks in two buildings and through two city blocks. The tasks involved walking in- and outdoors, across four staircases and two city blocks. We found that surface level changes were a source of uncertainty and even fear for all participants. Besides the white cane that many participants did not want to use, participants did not use technology in the study. Participants mostly used their vision, which was exhausting and sometimes deceptive. Our findings highlight the need for systems that support surface level changes and other depth-perception tasks; they should consider low vision people's distinct experiences from blind people, their sensitivity to different lighting conditions, and leverage visual enhancements.

Traditional television remote control presents frequent challenges to older adults. These challenges arise due to lack of feedback and poor design features such as labeling, size, spatial proximity, physical feel, etc. This paper describes the design of an accessible TV remote control (Potmote) created by employing potentiometers with Arduino to enhance tactile feedback and ease of channel selection with ergonomic controls. An experimental study was conducted with 15 older adults to understand how to design a system that would allow them to change channel numbers and volume levels. The result of experiment have shown positive feedback by the subjects.

We conducted a study with 25 older adults that aimed to investigate how older users interact with swipe-based interactions in mid-air and how menu sizes may affect swipe characteristics. Our findings suggest that currently-implemented motion-based interaction parameters may not be very well-aligned with the expectations and physical abilities of the older population. In addition, we find that GUI design can shape how older users produce a swipe gesture in mid-air, and that appropriate GUI design can lead to higher success rates for users with little familiarity with this novel input method.

People with vision impairment are concerned about entering passwords in public as accessibility features (e.g. screen readers and screen magnifiers) make their passwords more vulnerable to attackers. This project aims to use bend passwords to solve this accessibility issue, as they are harder to observe than PINs. Bend passwords are a recently proposed method for user authentication that uses a combination of predefined bend and fold gestures performed on a flexible device. Our inexpensive prototype called BendyPass is made of silicone, with flex sensors able to capture and verify bend passwords, a vibration motor for gesture input haptic feedback, and a button to delete the last gesture or confirm the password. Bend passwords entered on BendyPass provide a tactile method for user authentication, designed to reduce the vulnerability to attackers and help people with vision impairment to better protect their personal information.

In this paper, we build a case for incorporating socio-technical aspirations of different stakeholders, e.g. parents, care-givers, and therapists, to motivate technology acceptance and adoption for children with autism. We base this on findings from two studies at a special school in New Delhi. First, with six children with autism, their parents and therapists we explored whether fitness bands motivate children with autism in India to increase their physical activity. Second, with five parents and specialists at the same school, we conducted interviews to understand their expectations from and current usage of technology. Previous work defines a culture-based framework for assistive technology design with three dimensions: lifestyle, socio-technical infrastructure, and monetary and informational resources. To this framework we propose a fourth dimension of socio-technical aspirations. We discuss the implications of the proposed fourth dimension to the existing framework.
