Abstract

In this work, we propose the use of Transcranial Doppler Monitoring (TCD) as a tool to measure brain activity during the exposure to virtual environments (VE) that can be used in Augmented Cognition (AugCog) systems. The technique is non-invasive, and can be easily integrated with virtual reality (VR) settings. Its high temporal resolution allows the correlation of changes in brain activity to specific events in the VE. In this paper, the TCD technique is described, and results from two studies developed in our group combining TCD with VR are summarized. Possible applications of TCD in the AugCog field are finally discussed.
