Rey Figure Project

Machine-based quantitative scoring of the Rey-Osterrieth Complex Figure

We are currently working on a machine-based quantitative scoring of the Rey-Osterrieth Complex Figure (ROCF) test. If you have drawings from previous studies with a data usage agreement or if you are interested in a collaborating with us, please contact us:

Machine-based qualitative scoring of the Rey-Osterrieth Complex Figure

We have developed a prototype tablet application, in which the examinee draws the ROCF with a special pen on a tablet. The tablet can a) assess the sequence order of drawing the items, b) record the exact coordinate of each drawn pixel at each time point of the assessment, c) measures the duration for each pen stroke as well as total drawing time, and d) assess the pen stroke pressure. These additional information enable to standardize the qualitative measures.
