Emily

Emily was created by Image Metrics in California, the same company that created the graphics for the game Grand Theft Auto.

She is not real.

Emily was produced using a new modelling technology that enables the most minute details of a facial expression to be captured and recreated.

She is considered to be one of the first animations to have overleapt a long-standing barrier known as 'uncanny valley' - which refers to the perception that animation looks less realistic as it approaches human likeness.

“Ninety per cent of the work is convincing people that the eyes are real,” Mike Starkenburg, chief operating officer of Image Metrics, said.

“The subtlety of the timing of eye movements is a big one. People also have a natural asymmetry - for instance, in the muscles in the side of their face. Those types of imperfections aren’t that significant but they are what makes people look real.”
