Open the original (DOI 10.1038/s41598-018-25999-0)- What it measures
- The method used keystroke timing and pressure on a smartphone touchscreen during natural typing.
- What it does not show
- Only 33 people in total, in matched groups. The method uses touchscreen pressure as well as timing, so it does not describe a laptop keyboard.
