The figure shows the office and setup used at UH. During the experimental sessions, the systems continuously imaged the participants' faces with a thermal and visual camera. An additional visual camera angled down from the ceiling was imaging the participants' desktop area. The systems were also capturing the screen and keystrokes of the participants' computer, while two wearable devices were relaying the participants' physiological signals.
A thermal facial camera tracked perspiration levels around the nose and upper mouth to track stress levels of a study participant during report writing.
