HEI-Lab: Digital Laboratories for Environments and Human Interactions, is a R&D unit of Lusófona University. We develop, apply and converge knowledge from Psychology, Computer and Information Sciences, and Media and Communications into a transdisciplinary scientific outlook to push the boundaries of excellence in the study of the human-environment bidirectional interaction. HEI-Lab’s infrastructures in Lisbon and Porto provide cutting-edge equipment and software, including eye-trackers, psychophysiology devices, motion capture system, EEG, fNIRS, facial expression analysis software, VR headsets, and VR-based biofeedback system. Grounded on strong scientific foundations and innovative scientific methods, the outputs are translated into social, educational and healthcare settings, with large societal impact.
