According to Sean Andrist from the University of Wisconsin Madison, robots need to look away sometimes. Eye contact provides a basis for human social communication (which is why we seek to implement it in robots), but there’s a sweet spot for the amount of time we spend gazing into each other’s eyes.
In a conversation, humans don’t look at each other 100 percent of the time, says Andrist. When listening, we look at the speaker around 70 percent of the time. On the other hand, speakers only look directly at the other person around 40 percent of the time when talking.
