In the source's own words
“On non-AAC participants, the overall speed of text entry was similar to conventional smart keyboards, while the motor action savings was still substantial.”

Open the original (DOI 10.1038/s41467-024-53873-3)- What it measures
- A pilot with 19 participants who were not augmentative communication users typed on a mobile device by hand. The article's abstract describes the same pilot as showing motor savings in line with the simulation, with relatively small effects on overall typing speed.
- What it does not show
- A pilot with 19 people on one device, not a controlled test of everyday typing. It compares against smart keyboards, not against plain keyboards without prediction.
