- Development of an intracortical brain-computer interface (iBCI) typing neuroprosthesis for individuals with paralysis.
- The neuroprosthesis enables bimanual QWERTY keyboard functionality using attempted finger movements.
- Decoding accuracy is achieved with as few as 30 calibration sentences and improved with a 5-gram language model.
- Tested successfully with two clinical trial participants (one with ALS and one with spinal cord injury).
- Achieves typing speeds of 110 characters per minute (22 words per minute) with a 1.6% word error rate.
- Provides higher throughput and accuracy compared to current hand motor iBCI decoding technologies.
- Offers an intuitive, familiar, and easy-to-learn communication paradigm for paralyzed individuals.
