Open the original (DOI 10.1186/s12984-026-01902-1)- What it measures
- Participants were 20 healthy adults and 20 people with upper-limb impairment from neurological disease, who used the system to press an elevator button, pick up a TV remote and pour water.
- What it does not show
- A robotic-arm control system in a small study, not a computer voice control product. Accuracy is the share of speech recognized correctly for that system.
