Short summary

Stone stairs slowly wear as people walk on them, but these marks are often hard to interpret. This study used three-dimensional scans and computer modeling to connect tread shape with walking use and age. Tests on four staircases showed that the method could recognize different walking patterns and estimate use age with 94.4 % average accuracy while remaining stable when material aging and small scan errors were considered.
