Quality assurance in the evaluation of virtual prototypes by using eye tracking to optimize the customer requirements analysis


Improving Requirement Analysis in Mechanical Engineering through Virtual Prototyping and Interactive Attention Tracking in Virtual Reality

This project is funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) – project number 515614446 to research on new techniques to improve the quality of requirement analyses through the use of virtual prototypes and the analysis of attention during the inspection of those prototypes. To this ends, multimodal interaction data, in particular eye-tracking, is gathered and analyzed to improve the prompting procedures and disambiguate verbal reportings on requirements. The project title ReqET is a construct based on Requirements and Eye Tracking.

The project started in Fall 2023 and will continue until 2025. It is a joined project together with partner researchers from Quality- and Processmanagement at University of Kassel under the lead of Prof. Dr.-Ing. Robert Refflinghaus.

Exploration Scenario

Requirements regarding Bicycles

In our exploration scenario, we are using a virtual bicycle company as an example.
