We have the capabilities to acquire cognitive, physiological, and behavioral user state metrics concurrently, and in real time, while users work with an interface or product. We use Techsmith's Morae usability software in conjunction with our own recording techniques to measure traditional behavioral metrics such as speed, accuracy, key presses, mouse movement, and screen captures. 

A key element of our research is the use of non-invasive brain measurement to provide real time, objective information about users’ mental states.  Unlike other brain devices which require subjects to lie in restricted positions (fMRI), or to drink hazardous materials (PET), electroencephalography (EEG) and functional Near-Infrared spectroscopy (fNIRS) can measure users’ brain activity in realistic working conditions.  This makes EEG and fNIRS appropriate choices for brain measurement in the usability testing domain. 

Functional Near Infrared Spectroscopy

Our fNIRS device is Hitachi Medical’s ETG-4000.  This piece of equipment was selected because of its wide range of probes and holders that enable a variety of assessments.  This system can be configured to simultaneously take 24, 48, or 52 channel measurements, and it can be used to target various regions of the brain cortex (as opposed to just the prefrontal cortex).  With this device our usability work is at the cutting edge of non-invasive brain measurement research. 


With an eye toward its use in operational settings, we have a wireless, lightweight Electroencephalograph (EEG) from Advanced Brain Monitoring, Inc.. In addition to adding comfort and portability over wired EEG systems, the wireless EEG eliminates many of the noise artifacts that are caused by subject movement with more common wired EEG systems.


We also have an eyetracker and accompanying faceLAB software from Seeing Machines, Inc.The lightweight and portable eyetracker can be used inside or outside. We also have an extension to the eyetracker kit that enables its use in cars and cockpits.

Other Physiological Sensors

We also have sensors to measure galvanic skin response, breathing, and heartrate.
