Abstract

The aim of this pilot study was to assess the pros and cons of combining mobile neuroimaging with two different styles of highly immersive displays: one that is worn on the head; and the other that is entered. Specifically wearable Functional Near Infrared Spectroscopy (fNIRS) was combined with both an Oculus Rift and surround immersive projection technology (IPT). The first experiment assessed signal to noise ratio (SNR), freedom of movement and motion artefacts in both systems combined with fNIRS. Second experiment involved measuring hemodynamic response from the prefrontal cortex in IPT. Findings suggest that fNIRS is compatible with both approaches and the majority of movement they support. This work opens the door to measuring close to surface medium resolution neural response, to virtual stimuli in which people can naturally look and walk around. This has potential to improve ecological validity in applications range from neuroscience research to exposure therapy.
