Emotion economy

Chapter 8 endnote 38, from How Emotions are Made: The Secret Life of the Brain by Lisa Feldman Barrett.
Some context is:

At press time, Microsoft is analyzing facial photographs in an attempt to recognize emotion. Apple has recently purchased Emotient, a startup company using artificial intelligence techniques in an effort to detect emotion in facial expressions. Companies are programming Google Glass ostensibly to detect emotion in facial expressions in an effort to help autistic children. Politicians in Spain and Mexico are engaging in so-called neuropolitics to discern voter preferences from their facial expressions. Some of the most pressing questions about emotion remain unanswered, and important questions remain obscured, because many businesses and scientists continue practicing essentialism while the rest of us are figuring out how emotions are made.

Examples of the new "emotion economy" in technology:

• Microsoft: Emotion API

• Apple: Apple buys Emotient, a company that uses AI to read emotions

• Facebook: Like by smiling? Facebook acquires emotion detection startup FacioMetrics

• Google:
  • Cloud Vision API - "...can analyze emotional facial attributes of people in your images, like joy, sorrow, and anger."
  • Clinical Trial Will Test if Google Glass Can Help Kids with Autism

In politics:

• Spain: El análisis de las emociones de los políticos en el debate que revela quién sintió miedo, sorpresa o tristeza

• Mexico: Mexico’s Governing Party Vows to Stop Using Neuromarketing to Study Voters
