Electrodermal activity
• Electrodermal activity reflects the
activity of the sympathetic nervous
system and can be measured
through the changes in electrical
conductance of the skin

Case study – Trade fair
• EDA measurement data gathered from 10 sales
representatives marketing their company and its services
to buyers during one day (ca. 8-10 hours)
• These sort of events are usually somewhat hectic and
require ongoing focus and attention from the sales
personnel aiming to present their offerings to a potential
customer in a rather short time-slot, which can be
presumed to cause arousal to some extent
• Recognized need for automatic pre-processing and
visualization of the collected data
