Within the VEVEA project (original title: Verbesserte Ergebnisdarstellung in der Versorgungsforschung durch Eyetracking-Analysen; translated: Improved presentation of results in health care research through eye tracking analyses), a web-based application was created to support eye-tracking studies in the field of health care research. The application should support different variations of a study definition and at the same time record various parameters (e.g. display time of a page or number of page returns) for study execution.

The application was designed as a workflow engine, whereby the individual study variations were implemented through freely definable workflow definitions. Content and questionnaires were implemented using web technologies. For data storage, PouchDB was used locally and CouchDB on the server side, in order to be able to carry out the studies reliably even with poor Internet connection.
