Using Intelligent Character Recognition (ICR) to Understand Human Development | Children's Hospital Zurich

Opening up a Worldwide Unique Data Set With the Help of ICR

As part of the Zurich Longitudinal Studies, the University Children's Hospital Zurich studied the physical, motor, cognitive and social development of more than 1'000 children since the 1950s.

In this pilot project, the feasibility of digital data extraction from hand-filled questionnaires was tested, and the expected effort was hypothesized.
