Tweet reach : a research protocol for using Twitter to increase information exchange in people with communication disabilities

Objective: To (a) outline the background to research evaluating Twitter use by people with severe physical and communication disabilities participating actively in online communication forums for increasing information exchange and (b) illustrate a range of potential methods that might be applied in furthering research on the use of social media by people with developmental and acquired communication disabilities. Methods: The literature on communication disabilities, augmentative and alternative communication, and social media research informed the rationale for and design of three studies investigating the use of Twitter by people with communication disabilities. Results: To date, there is little information in the literature about how people with a range of communication disabilities might use Twitter to increase their access to information and help them to feel knowledgeable and in control of their own lives. In this paper, three studies are proposed to investigate the use of Twitter by people with communication disabilities

Comparison of eye tracking, electrooculography and an auditory brain-computer interface for binary communication: a case study with a participant in the locked-in state

Background In this study, we evaluated electrooculography (EOG), an eye tracker and an auditory brain-computer interface (BCI) as access methods to augmentative and alternative communication (AAC). The participant of the study has been in the locked-in state (LIS) for 6 years due to amyotrophic lateral sclerosis. He was able to communicate with slow residual eye movements, but had no means of partner independent communication. We discuss the usability of all tested access methods and the prospects of using BCIs as an assistive technology. Methods Within four days, we tested whether EOG, eye tracking and a BCI would allow the participant in LIS to make simple selections. We optimized the parameters in an iterative procedure for all systems. Results The participant was able to gain control over all three systems. Nonetheless, due to the level of proficiency previously achieved with his low-tech AAC method, he did not consider using any of the tested systems as an additional communication channel. However, he would consider using the BCI once control over his eye muscles would no longer be possible. He rated the ease of use of the BCI as the highest among the tested systems, because no precise eye movements were required; but also as the most tiring, due to the high level of attention needed to operate the BCI. Conclusions In this case study, the partner based communication was possible due to the good care provided and the proficiency achieved by the interlocutors. To ease the transition from a low-tech AAC method to a BCI once control over all muscles is lost, it must be simple to operate. For persons, who rely on AAC and are affected by a progressive neuromuscular disease, we argue that a complementary approach, combining BCIs and standard assistive technology, can prove valuable to achieve partner independent communication and ease the transition to a purely BCI based approach. Finally, we provide further evidence for the importance of a user-centered approach in the design of new assistive devices

The use of augmentative and alternative communication in Cyprus: Findings from a preliminary survey

Whilst augmentative and alternative communication has been used for over sixty years across many countries, in Cyprus it remains underdeveloped. The current study seeks to investigate the current AAC practices in Cyprus. Data were collected through electronically distributed questionnaires to all registered speech and language therapists (n = 330), contacted by the Cyprus Speech Therapy Association. The questionnaire comprised 12 questions, which were categorized into three sections: background information (educational level and clinical experience), training undergone (during or after completion of tertiary education) and participants’ AAC practices (caseload, assessment and intervention). The findings from the analysis of the returned data (n = 59) reveal that training provision on augmentative and alternative communication has positively influenced practice. Most of the participants received training in the specific field during their bachelor’s degree, rather than during later education. Life-long training on different language systems (including different assistive technology tools, such as symbols and talking products as well as methods such as the Picture Exchange Communication System) also played a pivotal role in their work. Regarding the assessment process, the findings show that whilst there are a number of standardized language assessment tools, the participants relied heavily on non-standardized tools and/or their clinical judgment. Regarding intervention, they reported using different language systems and a variety of Assistive Technology equipment. Several recommendations are made aimed at raising the profile of AAC services in Cyprus, especially with regards to training and assessment, as the findings show that these areas have not been addressed systemically thus far
