Toyota is designing a new technology that will react to the driver's mood. It will adjust how the car behaves depending on whether the driver is sad, happy, angry or neutral. The technology uses a camera to identify facial emotions by taking readings from 238 points on the driver’s face.
A driver’s mood can affect performance on the road. Research has shown that people with negative (and sometimes positive) emotions are distracted even more than those using a cell phone while driving.
