Ad firms using tools to help them read your mind• http://www.france24.com
Using gadgets to track eye movements, computer maps of faces to capture a momentary grin (approval) or squinting (anger), and sensors to measure perspiration or monitor brain activity, companies are mining consumers' raw emotions for information.
Traditionally, ad firms have measured the success of their campaigns through consumer surveys, but that technique has its limits.
"It's not that people won't tell you, they actually can't tell you why they're making the decision they're making," said Jessica Azoulay, vice president of the market intelligence practice at Isobar, a digital marketing agency.
The new techniques recognize that our purchase decisions are driven by both rational and emotional factors, and reflect research showing the brain takes in information on different levels.
They "enable us to capture many different types of emotions and to be able to profile the emotions that are happening very granularly on a second by second basis," said Elissa Moses, chief executive of the neuro and behavioral science business at Ipsos, a consultancy and market research firm.
