Brief Summary
The goal of this study is refine the usability of a BCI based communication platform. The study will take place in the greater Los Angeles area and will enroll up to 10 participants with late stage ALS. Each subject will receive a Cognixion Axon-R augmented reality brain computer interface and associated communication software. The study duration is 3 months for each participant. The key questions that will be addressed in this study are:
- 1.How quickly can participants learn and gain confidence with a pure BCI interface.
- 2.How effective are alternate input modalities including eye tracking for this use case.
- 3.Identify the extent to which generative AI based personalization impacts the communication quality.

Outcome Measures
Primary Outcomes (2)
System Usability Score
A score ranging from 0 to 100 that captures the usability the device. This is an essential characteristic of a device feasibility study.
3 months from training and setup of device.
Information Transfer Rate (ITR)
The rate, in bits per minute, of information transfer for each of the device modalities. ITR is measured using a standardized selection procedure.
3 months from training and setup of device.
Secondary Outcomes (1)
Words per Minute (WPM)
3 months from training and setup of device.
Study Arms (1)
Usability Study
EXPERIMENTALParticipants will utilize the Cognixion Axon-R device and associated communication software for practice and communication tasks as prescribed by the study administrator.
Interventions
A wearable augmented reality brain computer interface with self contained computer and software to enable communication using the device input and output capabilities.
Eligibility Criteria
You may qualify if:
- Must have someone (LAR) who can consent to their participation and who will be present in the study alongside the participant
- Must have a designated individual who can be trained on the Cognixion system
- Fluent in understanding English
- years or older
- Must have ALS and need an assistive communication device
- Must be able to engage in volitional eye opening and sustain eye opening independently for x duration
- Must have a way to communicate apart from using the Cognixion device such as vocalizations, head nod, eye blinks, eyebrow raises, etc. At a minimum, reliable way of communicating "Yes" and "No"
You may not qualify if:
- Disruption in English comprehension, either due to lack of fluent proficiency or due to a developmental/acquired language disorder (e.g. aphasia)
- Severely hearing impaired or deaf
- Sensitivity to flashing lights
- History of epilepsy and/or seizures
- Vision disorders restricting the visual field such as glaucoma, diplopia (double vision), nystagmus (involuntary eye movements)
- History of vertigo or other vestibular disorders
- Scalp that is prone to irritation, inflammation, injury, or infectious process
