Augmented Reality BCI Longitudinal Study for Persons with Late Stage ALS
Cognixion ALS BCI Longitudinal Study
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:
- How quickly can participants learn and gain confidence with a pure BCI interface.
- How effective are alternate input modalities including eye tracking for this use case.
- Identify the extent to which generative AI based personalization impacts the communication quality.
Key measures include:
ITR - information transfer rate SUS - system usability scale

Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
System Usability Score
Time Frame: 3 months from training and setup of device.
|
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)
Time Frame: 3 months from training and setup of device.
|
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.
|

|
Words per Minute (WPM)
Time Frame: 3 months from training and setup of device.
|
WPM is the number of words that a participant can speak in one minute.
This statistic is calculated by counting the total time from partner utterance until a response is spoken by the participant.
|
3 months from training and setup of device.
