With products like Google Glass being released and a rumoured Apple smartwatch on the way, the industry has been getting a lot more attention and, despite being in its infancy, is growing rapidly including in New Zealand, O'Brien says.
"In New Zealand the wearable technology industry is more than embryonic. There are companies, there are people doing it, there is an awareness, but it's not mature yet. Globally it's going through the same process but on a massive scale. It's huge."
New Zealand had been successfully occupying niche markets in the wearable technology industry, however O'Brien said there needed to be collaboration and more conversations to help companies to grow.
"It's early days. There's no blockbuster companies where you can say, 'That's the one that's taken wearable technology and sold billions of dollars of product.' So you can't say it's a mature market, it's early, it's emerging.
"But I have a lot of hope because it's growing rapidly."
O'Brien said the barriers in the wearable technology industry in New Zealand were also global ones. He noted that fashion and comfort both came into play, resulting in social issues as well as technological ones.
He hoped the gathering would allow companies to share ideas and work on the issues together.
"This is the start. I hope it becomes a regular thing, I hope other people will do more industry, niche-specific meetings and get together.
"I challenge people to do that and see where it goes."
With the growth of StretchSense and its applications for rehabilitation, gaming, sports and training, O'Brien saw no reason why New Zealand couldn't continue to be a leader in the wearable technology area.
Wearable technology - technology that connects with the body - has been around for more than a century.
Many people would not consider they were already using wearable technology such as pacemakers and hearing aids. The first electronic hearing aid was invented in 1898.

The iWatch is also expected to be compatible with Apple's Health app, which collects a user's fitness and wellbeing data, such as heartrate, from multiple sources and brings it together on one screen.
The device is rumoured to feature a 2.5-inch arched rectangular display supplied by LG.
At next month's event, Apple is also expected to launch the iPhone 6, which will feature a larger 5.5in screen.
The iPhone 6 will be powered by new operating system iOS 8, which Apple unveiled at its worldwide developers conference in June.
