英文摘要
Project Summary
Machine learning (ML) and Natural Language Processing (NLP) have the potential to transform communication
for patients with neurodegenerative disease through personalized and real-time augmentative and alternative
communication (AAC) devices. Individuals with severe communication impairments who can no longer control
their daily conversations or participate in previous life roles want AAC devices. And they want them to work – to
be reliable, effective, and fast. ML and NLP are emerging as promising tools to bridge current technology and
next generation devices for individuals with the most severe speech and physical impairments, like the RSVP
Keyboard™, a brain-computer interface (BCI) being developed by the parent grant. BCI systems for
communication are referred to as AAC-BCIs. NLP efforts to combine large public data sets with private data sets,
such as personal email messages, promise to give individuals with communication impairments their own
personalized language models, models that are sufficiently robust to get closer to real-time communication. The
focus on getting AAC-BCIs to work with machine learning, however, has led to a critical oversight in the field: an
inadequate understanding of why individuals want next-generation devices and what trade-offs they are willing
to make for faster and more personalized communication. The turn to ML brings this oversight into sharp relief.
Individuals should provide input about the data sets used to construct their personal language models, but this
raises important ethical questions about what individuals value, how they understand their identity, and what
trade-offs they are willing to make relative to their personalized communication data. The goal of this supplement
is to fill this gap in understanding so that researchers can implement ML into next generation AAC-BCI systems
in a way that is sensitive to the ethical concerns of future users. There are four components to this ethics
supplement: (1) to design a toolbox of ethics vignettes tailored to ethical concerns raised by both BCI
communication and ML; (2) to administer monthly vignette-based online ethics surveys to individuals with severe
communication impairments due to motor neuron disease (e.g., ALS) (n=25) or movement disorders (e.g.,
Parkinson's disease) (n=25); (3) to conduct semi-structured vignette-based interviews with individuals with pre-
clinical or mild communication impairment due to motor neuron disease (n=10) or movement disorder (n=10).
Components (2) and (3) will employ an iterative, parallel mixed-method approach. Trends in Likert-style online
responses to ethics vignettes in the severe communication impairment cohort will be used to inform and modify
the semi-structured interview prompts asked of the pre-clinical or mild impairment cohort. In parallel, themes
emerging from direct content analysis of interviews will be used to refine online survey questions. Results of this
iterative, mix-methods approach will be used (4) to outline a framework of core ethical domains and preliminary
tools (vignettes and discussion prompts) that AAC-BCI researchers can use to assess ethical concerns while
developing and iteratively refining communication technology for personalized language models.
