PluColl - The UNIPEN/NICI/HP data collection of Summer/Autumn 1994
收藏资源简介：
This file contains 'on-line' handwritten words data collected on a thin Wacom PL100V integrated tablet and grey-scale LCD screen (i.e., long before the iPad!) in Summer/Autumn 1994 in a collaboration project between the handwriting group at Nijmegen University and Hewlett-Packard Bristol. HP donated this data to the International Unipen Foundation. <strong>Not</strong> within the Unipen data set (10.5281/<em>zenodo</em>.1195802) were the individually labeled characters, which<strong> are included </strong>in this data set. ___________________________________________________________________________________________________ <strong>Files overview</strong> plucoll-1994-2023.pdf Our report to HP, from 1996.
