ChewIt, developed by Pablo Gallego (ME student) under the supervision of Dr. Denys Matthies and Associate Professor
Imagine a device that feels like and is no bigger than a piece of chewing gum, which allows you to answer the phone
simply by biting down on it.
We now have the technology with ChewIt, a novel interface developed by the Augmented Human Lab team at the Auckland
Bioengineering Institute (ABI), University of Auckland.
It’s a tiny piece of technology encased in a flexible custom-made PCB that you pop in your mouth and which allows for
discreet and hands-free interaction with your phone, your computer, your smartwatch and so on.
ChewIt was developed by the team lead by Associate Professor Suranga Nanayakkara who made international headlines in
recent years with the FingerReader, a prototype device worn on the finger that allows users to point at words (those on
the spine of the book, or in a restaurant menu) which is then translated to voice.
Since moving from Singapore to New Zealand last year, Nanayakkara and his team have produced a number of innovative
technologies. Along with ChewIt they have also developed GymSoles, a pressure sensitive insole that vibrates, giving
users vibrotactile feedback to help them maintain the correct body posture.
GymSoles was tested and shown to be effective on people performing certain exercise such as squats and dead-lifts, to
help them maintain the correct Centre of Pressure, but they could be used to improve posture in myriad contexts.
Nanayakkara has an almost philosophical approach to technology. He wants to address what he says is a mismatch between
what technology has to offer and innate human behavior, and his research focused on developing technologies that are
more responsive to innate human behavior rather than oblige humans to adjust to the requirements of the technology.
“We want to design and develop systems that can understand the user rather than us having to tell the technology what to
do every time – technologies that can understand us much better than technology currently does.”
He defines such technologies as ‘assistive augmentation’. “It’s when the system understands the abilities, behavior and
emotions of the user. And when the system is unobtrusive and integrated with our body or our behavior.
“And it should be about strengthening and extending the physical and sensorial abilities of the user, allowing them to
do what they couldn’t do before. When you meet all three measures, that’s assisted augmentation.”
