The goal of the project is to develop a novel gaze-independent brain-computer interface (BCI) based on code-modulated visual evoked potentials (C-VEP) for people living with late stage ALS. This repository contains code for the offline protocol of the said project.
Contents: Different versions contain the various stages of the experimental paradigm and analyses scripts used for the project.
- version 0: preliminary experimental paradigm with parallel flashing with two classes. The stimuli displayed are the letters 'Y' and 'N'.
- graz: This is the official folder for the submission made to the 2024 Graz BCI conference at TU Graz. For a detailed overview of the experiment and analyses involved, refer to arxiv
- version 2: The most upto date script for the experiment will be found in version 2. The experiment consists of parallelly flashing stimuli containing 5 different shapes. The analysis folder now contains analyses for eye tracking data.
Each version (version_2 being the most up to date) contains an experiment and an analysis folder. For usage of specific versions, please refer to their respective readme.md file.
