We describe preliminary research that attempts to quantify the level of trust that exists in typical interactions between human users and their computer systems. We describe the cognitive and emotional states that are correlated to trust, and we present preliminary experiments using functional near infrared spectroscopy (fNIRS) and electroencephalography (EEG) to measure these user states. Our long term goal is to run experiments that manipulate users’ level of trust in their interactions with the computer and to measure these effects via non-invasive brain measurement.
