ZenTrader, an emotion-reactive interface

Abstract

We explore the concept of interactive technology that is implicitly controlled by emotions, via wearable physiology sensors. We describe a proof-of-concept emotion-reactive stock trading software that interrupts trades that appear to be entered under an unusual amount of stress. We describe a galvanic skin response (GSR) sensor armband that broadcasts stress events via Bluetooth to a prisoner's dilemma game application on an Android phone, which alters its behavior when the user is stressed. We carried out pilot evaluation of this system's effects on the consistency of decisions made under stress. © 2011 Springer-Verlag.
