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

- Prototype found valid for field research by the Finnish Institute of Occupational Health in 2015
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
