Adoption and usability of a braille communication assistive device (CAD) for face-to-face and remote communication in two users with deafblindness
Bibliographic record
Abstract
Purpose There are currently no best practice training methods with communication assistive devices (CAD) for individuals with deafblindness using a braille display notetaker connected to an iPhone. Therefore, to capture adoption and usability of braille CAD in clinic, the Technology development and evaluation model of Schulz et al. (2015) was applied. Objectives were 1-to measure the level of difficulty in life habits involving communication before, during and after training with a braille CAD, 2-to document the feasibility of training for face-to-face and remote communication, 3-to simulate and assess communication exchanges with an unknown hearing person face-to-face, and 4-to document the long-term usability and adoption of CAD.Methods A case study involved a 68-year-old woman and a 55-year-old man with Usher syndrome who have recently learned braille. Therapies were 90 min./week and 120 min. every two weeks. Data were collected with the Life habit 4.0 adapted (-3, 0, 6, 18 months), clinician workbook (monthly), filming scenario testing of communication (at 8–10 months) and observation grids (experience of usability, communication interaction).Results Results at 18 months revealed that communication with hearing persons, travelling outside the home alone and conducting non accessible leisure were still very difficult to impossible. Clinicians accomplished 12 modalities in therapy sessions. They encountered 14 challenges for face-to-face communication due to the instability of VoiceOver® with Notes® and French language skills. Scenarios involving commercial exchanges were not efficient (buying a pen, renewing health insurance card).Conclusion Adoption of a braille CAD for remote communication has proven satisfactory, effective but not efficient. Face-to-face communication has been non-adopted.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
