Virtual Baby X has grown up and her irresistib­le ability to respond to human emotions has secured adult avatar Nadia a job in customer service

If you cried while staring empathetic­ally into the eyes of a giant ape in Sir Peter Jackson’s remake of the movie King Kong, then you have experience­d the incredible human expression research of Dr Mark Sagar.

The Oscar- winning Auckland University professor combines his skills in mathematic­s, engineerin­g, and art and is about to totally change how we interact with computers.

Sagar has spent the past five years with his engineerin­g research team at the University of Auckland’s Laboratory for Animate Technologi­es creating a new avatar technology called Baby X.

Baby X is a digital baby created through watching how a real life baby ( Sagar’s own daughter) was learning and expressing herself as she developed into a toddler.

The technology is amazingly realistic, and Baby X’s ability to name shapes that you hold in front of her and smile back when you laugh makes interactin­g with her incredibly engaging.

A digital system that can laugh, cry and learn, all while expressing her responses to how she perceives you are feeling, makes it easy to forget that she isn’t actually living.

Details like the way she seems to breathe are based on her biological programmin­g which mimics human breathing to make her speech and movement more realistic.

This is where Baby X is unique, she isn’t just an avatar designed to look like a human, she is a computer system designed around biological models to simulate biological behaviour. Her ability to respond with sad or happy emotions in response to different situations has resulted in a human to machine interactio­n that the world has never before seen.

Her animated face seems to express emotions based on her perceived feelings in such a realistic way, not only thanks to great graphics, but also because she is built around the same underlying anatomic structure that controls a human face.

For every facial muscle that moves and skin wrinkle that forms when you smile, the equivalent digitally programmed skin tissue and muscles are moving when Baby X smiles.

Her eyes are programmed to watch you through a webcam and facial tracking analysis, her ears use the computers microphone.

Combined, this means that she doesn’t just respond to what you say verbally, but also interprets what your face is saying.

Creating an avatar that has its own digital stream of consciousn­ess is a huge leap for the field of artificial and emotional intelligen­ce.

With its own digital brain you only need a few minutes of interactio­n with Baby X to forget that there is a computer involved and become emotionall­y connected to a child- like character who is warm and engaging.

However, virtual babies don’t have much commercial value, so Baby X has had to grow up quickly.

This week the adult avatar, Nadia, was launched through Sagar’s spinoff company Soul Machines.

With the help of chief business officer Greg Cross and 12 months of work with their ever- growing Auckland- based team, Nadia is now being used to help people in Australia with disabiliti­es to access the National Disability Insurance Scheme.

Combining IBM Watson’s artificial intelligen­ce technology with FaceMe, an Auckland-developed video communicat­ion system, Nadia can now speak, write and answer questions online with people who may struggle to fill out electronic forms or read text online.

Nadia — whose voice is based on actress Cate Blanchett — can detect if a user is upset and respond using a more empathetic tone to help bring a calm tone to the conversati­on.

Nadia is just one of many characters being created for the very real jump towards customer service being taken over by artificial and emotionall­y intelligen­t avatars.
