philips design: rationalizer concept

image: philips design

philips design worked with the dutch bank ABN AMRO to develop the rationalizer, an emotion sensing system for investment traders. the design is intended to give serious at home traders an emotional mirror which reflects their feelings. the concept is intended to combat research which shows home investors are influenced by emotions which can compromise their ability to trade objectively. the device uses an on-wrist monitor to track the user and a small display, which alerts the user when it may be time to take a break or re-consider their actions. the bracelet monitors the arousal level of the user and transforms the data into a pattern. the higher the arousal level goes, the more intense the pattern becomes. the design requires no technical knowledge and works as an ambient display, letting the user work unobstructed by technology.
