a trio of wearable-tech experts from across the spectrum of devices discussed the tech and the roadblocks to widespread use from consumers. Currently, there's still a challenge with getting the public to want to wear anything, let alone a smartwatch or activity tracker. Not only does the device need to look amazing, but it also has to provide a function that we can't live without.

For Co-founder of Narrative Oskar Kalmaru (the outfit that makes the Clip life-logging camera) the usefulness of wearables is a software issue. "[It's] making it smart enough to do something for you." With a large number of Americans using either activity-tracking gadgets or services, the interest is clearly there -- even now in infancy -- and Kalmaru is convinced the sector will continue to grow with more improved software. there's forming the habit of wearing an object like a piece of jewelry every day.
