Brain-to-Text Decoding: A Non-invasive Approach via Typing, Jarod Levy et al., arXiv (preprint), 2025, Abstract.
Open the original- What it measures
- The volunteers were people without neurological conditions who typed sentences while their brain activity was recorded.
- What it does not show
- Healthy volunteers who can type are not the people who most need a brain interface. The authors' results do not show that the method works for people with paralysis.
