Normal-hearing people use sound as a cue to recognize various events that occur in their surrounding environment; however, this is not possible for deaf and hearing of hard (DHH) people, and in such a context they may not be able to freely detect their surrounding environment. Therefore, there is an opportunity to create a convenient device that can detect sounds occurring in daily life and present them visually instead of auditorily. Additionally, it is of great importance to appropriately evaluate how such a supporting device would change the lives of DHH people. The current study proposes an augmented-reality-based system for presenting household sounds to DHH people as visual information. We examined the effect of displaying both the icons indicating sounds classified by machine learning and a dynamic spectrogram indicating the real-time time–frequency characteristics of the environmental sounds. First, the issues that DHH people perceive as problems in their daily lives were investigated through a survey, suggesting that DHH people need to visualize their surrounding sound environment. Then, after the accuracy of the machine-learning-based classifier installed in the proposed system was validated, the subjective impression of how the proposed system increased the comfort of daily life was obtained through a field experiment in a real residence. The results confirmed that the comfort of daily life in household spaces can be improved by combining not only the classification results of machine learning but also the real-time display of spectrograms.

Historically, the field of deaf education has revolved around language planning discourse, but little research has been conducted on Deaf and Hard of Hearing (DHH) students with additional disabilities as dynamic multilingual and multimodal language users. The current study focuses on the language planning process at a school serving DHH and Deaf–Blind students with varied additional disabilities. A previous Total Communication philosophy at the school was implemented in practice as Simultaneous Communication (SimCom) and later revised as a multimodal-multilingual approach with the goal of separating American Sign Language (ASL) and English and using multimodal communication such as tactile ASL and Augmentative and Alternative Communication (AAC). To implement this philosophy without reverting back to SimCom, the school employed a language planning process using action research to reflect on cycles of improvement. A grounded theory approach was used to identify and analyze themes over a three-year period of language planning and professional development in multimodal communication. Triangulated data includes language planning artifacts and an online survey of staff perceptions—analyzed by coding concepts and categories, relating concepts to define translanguaging mechanisms and attitudes, and developing an overarching theory on how a school values translanguaging after 3 years of valuing complete access to language. In the context of a multilingual, multimodal language planning cycle, developing a shared language ideology guided by how Deaf, DeafBlind, and Deaf-Disabled (DDBDD) people use language emerged as an overarching theme that promoted dynamic languaging and understanding of strategies for effective communication.

Sign language is the main communication way for deaf and hard-of-hearing (i.e., DHH) people, which is unfamiliar to most non-deaf and hard-of-hearing (non-DHH) people. To break down the communication barriers between DHH and non-DHH people and to better promote communication among DHH individuals, we have summarized the research progress on sign language translation. We provide the necessary background on sign language translation and introduce its four subtasks (i.e., sign2gloss2text, sign2text, sign2(gloss+text), and gloss2text). We distill the basic mode of sign language translation (SLT) and introduce the transformer-based framework of SLT. We analyze the main challenges of SLT and propose possible directions for its development. Full article

Deaf and hard-of-hearing (DHH) populations are understudied in health services research and underserved in healthcare systems. Existing data indicate that adult DHH patients are more likely to use the emergency department (ED) for less emergent conditions than non-DHH patients. However, the lack of research focused on this population’s ED utilization impedes the development of health promotion and quality improvement interventions to improve patient health and quality outcomes. The purpose of this study was to develop a conceptual model describing patient and non-patient (e.g., community, health system, provider) factors influencing ED utilization and ED care processes among DHH people. We conducted a critical review and used Andersen’s Behavioral Model of Health Services Use and the PRECEDE-PROCEED Model to classify factors based on their theoretical and/or empirically described role. The resulting Conceptual Model of Emergency Department Utilization Among Deaf and Hard-of-Hearing Patients provides predisposing, enabling, and reinforcing factors influencing DHH patient ED care seeking and ED care processes. The model highlights the abundance of DHH patient and non-DHH patient enabling factors. This model may be used in quality improvement interventions, health services research, or in organizational planning and policymaking to improve health outcomes for DHH patients. Full article

Sign language services are provided so that people with hearing loss are not alienated from socially and politically important information through TV broadcasting. In this paper, we conducted a user survey and evaluation of the current sign language services for deaf or hard-of-hearing (DHH) people, and solutions were proposed for the problems found in the course of the analyses. To this end, a total of five stages of research were conducted. First, the communication problems experienced by DHH individuals and previous studies on their language and information acquisition were investigated. Second, the most typical types of information delivery channels via TV were defined as news, discussions, and weather reports, and by investigating the actual sign language service cases for each type, three visual information delivery elements were identified: sign language interpreters, reference videos, and subtitles. Third, a preference survey, an interview survey, and an eye tracker experiment on the DHH participants were conducted with varying arrangement options of information delivery elements. Fourth, based on the results of the investigations and experiments, the options to be considered when arranging information delivery elements were compiled. The results showed that the sign language interpreter, which is the first element of information delivery, should be presented in a size clearly visible because the visibility of their facial expressions is important. In addition, it is recommended to present the interpreter without a background since DHH participants did not prefer the presence of a background. As for subtitles, which is the third element of information delivery, it was confirmed that the provision of sign language interpretation and subtitles together helped DHH participants to understand the contents more quickly and accurately. Moreover, if there are multiple speakers, individual subtitles for each speaker should be provided so that the viewers can understand who is talking. Reference videos, which are mainly placed on the screen background, the second information delivery element, were considered less important to DHH participants compared to sign language interpreters and subtitles, and it was found that DHH participants preferred reference videos to be visually separated from sign language interpreters. Fifth, based on the overall results of the study, a screen layout design was proposed for each type of information delivery element for DHH people. Contrary to the general conception that there would be no problem in viewing information-delivering TV broadcasts by DHH people simply by placing a sign language interpreter on the screen, the results of this study confirmed that a more delicate screen layout design is necessary for DHH people. It is expected that this study will serve as a helpful guide in providing better sign language services for TV broadcasts that can be conveniently viewed by both DHH and non-disabled people.

The COVID-19 pandemic poses a great risk to older people with hearing impairment, who face a higher threshold of external communication after the implementation of the emergency isolation policy. As part of a study on the optimization of external communication among the deaf and hard of hearing (DHH) population in central China, this study employed a qualitative research method based on in-depth interviews to explore the needs and difficulties faced by the older DHH group in external communication during public health emergencies in Wuhan, China, in the context of the COVID-19 pandemic. The results showed that older DHH people had weak reception of critical information about the epidemic, and had suboptimal access to medical care during emergency quarantine, which increased interpersonal communication barriers to this group. The current findings highlight the urgent need for targeted strengthening of the original emergency communication and coordination mechanisms in public health emergencies, and for improving policy inclusiveness for older DHH individuals during the COVID-19 pandemic and emergencies alike.
