In this paper the authors present a virtual reality system for visualization, navigation and reviewing of(More)
The usage of multimodal user interfaces has revolutionized many different activities. However, most of the interactive technologies deployed in real world engineering contexts are still difficult to use, especially when engineering teams need to collaboratively visualize and review large-scale 3D CAD (Computer-Aided Design) models. This is the case of the(More)
This paper tries to identify increases in user frustration when using Eye-Tracking devices as compared to common interfacing devices like a standard mouse. For this, we used an electroencephalograph (EEG) to measure frustration levels while users navigated within a maze using each of the referred devices. Results from the analysis performed on the EEG data(More)
