Evaluating The Need For Validation Of Accesstools For Deaf Individuals: A Qualitative Study

INTRODUCTION

Individuals with hearing disabilities often inhabit different sensory worlds than hearing individuals. When discussing accessibility and universal design people who are Deaf, deaf, and hard of hearing are placed in the same category of deaf*. The National Deaf Center is now using the term deaf in an all-inclusive manner, to include people who identify as Culturally Deaf, deafblind, deafdisabled, hard of hearing, late-deafened, and hearing impaired due to the fluidity of identity [1]. However, due to individual auditory and visual needs, it is suggested to separate each into their own subcategory. In 2010, the Department of Justice revised the regulations for Title II and III of the Americans with Disabilities Act of 1990 (ADA). These new standards, known as “2010 Standards,” set the minimum requirements for both scoping and technical standards for newly designed and altered public buildings to be accessible to and usable by individuals with disabilities [2]. The minimum requirement often focuses on audio amplification systems and providing hearing aid compatible systems. It is the design of the building and environment that often inhibit the sensory experience of individuals.

AccessTools is a iOS application, developed through the Access Ratings for Building Project (AR-B), that allows trained raters to evaluate the accessibility of a building [3].

One of the primary concerns when discussing Universal Design and accessibility is the focus on mobility disorders, and vision impairments. It is the aim of this paper to shift the focus to include hearing disabilities and validate the need to explore the content of AccessTools

METHODS:

Design

In this qualitative study, we explore the need to validate AccessTools for the deaf populations. A qualitative method was chosen for this research due to the goal of understanding people’s beliefs, experiences, and interactions [7]. In order to determine the need of addressing the content of AccessTool, an exploratory approach was needed to understand the perspective from deaf individuals. We first searched the current literature that explores building design, and the architecture with deaf accessibility in mind. Next, a structured interview/ discussion is performed with two expert participants to analyze the taxonomy of AccessTools, and provide suggestions on how to expand the criteria. .

Participants

Structured Interview/ discussion

Recruitment of participants was performed through convenience sampling at the University of Wisconsin- Milwaukee Accessibility Resource Center. Two participants were recruited for this study, one participant a deaf and hard of hearing specialist at the University of Wisconsin- Milwaukee. One identified themselves as deaf, and one hard of hearing, both are fluent in American Sign Language.

Data Collection

Literature Review

To begin this research, a detailed literature search was performed searching various academic journals and databases, through the UW-Milwaukee Library System including Google Scholar, PubMed, PsychInfo, Sociological Abstracts, American Society of Aging, Audiology Holding, Hearing Health Foundation and CINAHL. The criteria of the articles had to be peer-reviewed and published between 2000-2019. Large number of words were used to search articles, including these keywords in the domains of, “Environmental Design,” “Architectural accessibility AND hearing,” “Community Participation AND barriers,” “Deaf Design.”

Structured Interview/ discussion

To perform the structured interview, participants scheduled an hour and a half face to face interview. During the interview, the research and goals were presented to the participants. Once both understood and agreed to participate, background information was taken from both participants. Participants were then provided with an electronic copy of the unpublished taxonomy of AccessTools, and asked to review each question and criteria listed. Comments that were made were highlighted and noted on a separate word document.

DATA ANALYSIS

Literature Review

All articles were analyzed by researcher for content that related to the study.

Structured Interview/discussion

Participants analyzed the taxonomy data, noted missing content. The final analysis was performed by student reviewing the results of the interview, and summarizing the data. 

FINDINGS

Literature Review

Our literature search found a gap in the scholarship, and new evidence is needed. Several articles were found using the criteria’s and terms, however only a few of them were relevant to addressing building design with deaf individuals in mind.  The newest publication was a thesis Deaf- First Architect published in 2017 [4]. This article focused on schools for the deaf, and how the building impacted the student’s experience. An article published in the AI Journal of Technology, “Research on Barriers in Architecture for Hearing Impaired Person” [5] but was able to be roughly translated to English, discussing barriers deaf people in Japan experience with buildings, and public transportation. Several other articles were found, see Table 1 for example of search results. Several articles were found, however were unable to be used due to non-relevant content. 

Structured Interview/discussion

AccessTools has many considerations for mobility disabilities but lacked information on visual cues with hearing deficits in mind. About 20 structures were identified for the need to expand the content, with about several suggested areas to address. See Table 2 for a summarized result of findings. Some main points suggested includes, flooring need to be assessed for acoustic compatibility including carpeting to reduce reverberation and help reduce glare. Carpeting should also be considered to follow ADA standards and have a height less than ½” to ensure accessibility for wheelchair users [6]. Doorways with automatic swing doors should either include a window, or visual light warning cue for doors opening, similar to and provide contrasting colors for deaf-blind and individuals with usher syndrome. Public restroom should have lights attached to their emergency alarms, and stall door needs to provide enough space to view occupancy of facilities, but also provide privacy. Hallways and routes should provide contrasting colors for people communicating with sign language to see the other person, as well as wide enough for two people to walk side by side. If stairwell are presents, there should be enough visual cues to avoid running into other people.

DISCUSSION/ LIMITATIONS:

This study aimed to search the literature and analyze the taxonomy of AccessTools to support the need for further content validation for deaf populations. There are several limitations to this study. First, there was a small sample size for the population. Further research will need to increase the sample size, and have a wider represented population. Ideally individuals who identify as hard of hearing, deaf-blind, and parents of children who are deaf should be represented. This study does present some bias through focusing on only a certain participant and data collected comes from a perspective that is searching for the absence of proper representation. The data analysis of this research was conducted by an expert, who was a member of several committees and continues to participate, advocating for accessibility of deaf* individuals. This individuals experience is unique and provides only one perspective to this experience. However, if two participants have shared similar experiences, it could be assumed there are more facing the same issues. This study only focused on the unpublished taxonomy of AccessTools, however this should be looked at again once it is live on the app. Due to only two individuals looking at the taxonomy, future research should explore more focus groups of experts reviewing the taxonomy and making suggestions.  

CONCLUSION

By focusing to increase the inclusion of the deaf population, we have opened the conversation to advocate for more consideration in the taxonomy of AccessTools. The results from our literature review was expected, since deaf is typically seen as a less visible disability. The results from our structured interview provided new insights and perspective needed to be taken when looking at the content of AccessTools. Further research will have to focus on what types of questions trained raters should be looking for increasing accessibility for deaf individuals.
