Christchurch computer scientist Dr Swati Gupta prefers people to programming, but it’s her experience in human-computer interaction that’s led to what may be a breakthrough for youngsters with autism.
A senior research scientist at Callaghan Innovation, Gupta moved to New Zealand three years ago from Singapore, where she was involved with a project for dementia patients. She admits she was “clueless” about autism until she began working with speech and language teachers at Hillmorton High School’s Upland Unit, a specialist facility in Christchurch for students with very high needs.
“I spent time in class and I saw a lot of repetition,” she says. “It was, ‘Johnny, do you want to ask Mary a question? Johnny, do you want to ask Mary?’ – over and over and over. And Johnny didn’t want to ask Mary, but eventually he did, and then Mary didn’t want to answer. So it was a real challenge.”
The app is aimed at five- to 20-year-olds and uses symbols to prompt language and conversation. It’s not a game you play solo but rather acts like a mirror to help two people engage. Early signs are positive, with parents reporting increases in eye contact, attention span and social interaction.
Her work has been awarded two grants totalling $50,000 from the KiwiNet Emerging Innovator Fund, a philanthropic initiative backed by the Norman F. B. Barry Foundation to help scientists with “disruptive new ideas” work alongside business to take their discoveries to market.

Another recipient, Otago University PhD student Sean Mackay, has been given $25,000 to help develop a treatment for strawberry birthmarks, a disfiguring and occasionally life-threatening type of vascular tumour that affects one in 10 infants. He’s working with a team to develop a targeted treatment that uses nanotechnology to literally squish drugs directly into the tumour through the skin. Other projects supported by the fund include research into video fingerprinting for border-control scanning, and biodegradable “nano-webs” that can be spread over crops to help with pest control.
Gupta’s grants have enabled her to run several trials with Talk With Me, both here and in India, where she was born. “It’s a very simple idea; I didn’t know how good it was, so we wanted to see if it works,” she says. “I went back to the Upland Unit with my tablet and two girls came in, one with quite severely restricted conversation skills. They sat down and started playing. Ten minutes later, they were still playing. I didn’t realise how huge that was then.”
It was only when the teacher told her the girls “don’t speak” that she realised the app’s true potential. “It was the first time the girl had asked the other one what her favourite animal was – and they’d been studying together for five years.”
Gupta’s now trying to secure commercial funding of at least $200,000 to get an initial “alpha version” of Talk With Me into the New Zealand market. The app, which could prove useful for people with speech and language disorders, cerebral palsy or ADHD, might also help those with autism as they grow into adults.
“It could work for dating scenarios,” she says. “They are often not sure what to ask, and the platform lends itself to being used by adults, but we haven’t trialled it yet.”
