An "I’m on Tilt" Detector Bracelet

Imagine a device that tells you when you have too much emotional intensity to make rational decisions. This emotion-detecting bracelet from Philips is designed for day traders, but it might functionally equally well for online poker players:

It acts as an ’emotion mirror’ in which the intensity of the user’s feelings is reflected. Research shows that home investors do not act purely rationally: their behavior is influenced by emotions, most notably fear and greed, which can compromise their ability to take an objective, factual stance. This insight led to the Rationalizer concept in which online traders are alerted when it may be wise to take a time-out, wind down and re-consider their actions.
