Software helps children with autism to see emotions
Like many children with autism, Julian Brown from San Jose has trouble reading emotions in people’s faces — one of the biggest challenges for people with the neurological disorder.
The facial recognition software was developed at Stanford University and runs on Google Glass, a computerised headset with a front-facing camera and a tiny display just above the right eye.
Julian is one of about 100 children taking part in a Stanford study to see if “autism glass” therapy can improve their ability to interpret facial expressions.
“There’s not a machine that can read your mind, but this helps with the emotions, you know, recognising them,” said Julian.
Julian wears the device each day for three 20-minute sessions when he interacts with family members face-to-face — talking, playing games, eating meals. The programme runs on a smartphone, which records the sessions.
When the device’s camera detects an emotion such as happiness or sadness, Julian sees the word “happy” or “sad” — or a corresponding “emoji” — flash on the glass display. The device also tests his ability to read facial expressions.
“The autism glass programme is meant to teach children with autism how to understand what a face is telling them. And we believe that when that happens they will become more socially engaged,” said Dennis Wall, who directs the Stanford school of medicine’s Wall Lab, which is running the study.
Stanford student Catalin Voss and researcher Nick Haber developed the technology to track faces and detect emotions in a wide range of people and settings.
“We had the idea of basically creating a behavioural aide that would recognise the expressions and faces for you and then give you social cues according to those,” said Ms Voss, who was partly inspired by a cousin who has autism.
Google provided about 35 Google Glass devices to Stanford, but otherwise has not been involved in the project. The Silicon Valley tech giant stopped producing the headset last year after it failed to gain traction, but the device found new life among medical researchers.
Brain Power, a Massachusetts-based startup, is also developing Google Glass-based applications to help children with autism improve their face-reading abilities and social skills.
“Glass and wearable technology are the future. They’re going to play a pivotal role in how we understand, manage and diagnose disorders like autism,” said Robert Ring, chief science officer at Autism Speaks.
Currently, many children with autism learn to read facial expressions by working with therapists who use flashcards with faces expressing emotions. The Stanford team hopes autism glass can provide a convenient, affordable therapy that families can do at home.
“Kids with autism are not getting enough of the care that they need for as long as they need it, and we need to fix the problem,” said Mr Wall.
If the study shows positive results, the technology could become commercially available within a couple years, Mr Wall said.
Julian gives the device positive reviews: “I really think it would help autistic people a lot.”
