Columns:

01 index
02 ID of participant
03 sample name
04 µ_(slow) friction coefficient at slow speed
05 µ_(fast) friction coefficient at fast speed
06 v_(slow)[mm/s] velocity (slow)
07 v_(fast)[mm/s] velocity (fast)
08 F_F_(slow)[N] friction force at slow speed
09 F_F_(fast)[N] friction force at fast speed
10 F_N_(slow)[N] normal force at slow speed
11 F_N_(fast)[N] normal force at fast speed
12 answer to the question "For which of the two speeds do you feel more resistance against the movement of your fingertip over the surface?”

All values are median values of the tactile exploration traces.
