Getting lost at the Wearable Tech conference (pictures)

At New York's Wearable Tech Expo this week, a variety of fringe devices lurked among discussion panels and keynotes. Here's Scott Stein trying on the Vuzix M100 Smart Glasses, last seen at CES.

Unlike Google Glass, the M100 has a metal headband and boomlike camera/screen attachment. It can be worn over either eye. Under the hood, the M100's raw specs are close to that of Glass'.

The M100 cuts a conservative look.

The earpiece is a traditional style versus the bone conduction approach on Google Glass.

The Kreyos Meteor watch was undercover at the conference, but made a subdued appearance with all its clip/lanyard accessories. The watch, coming later this year, has its own fitness apps and speakerphone and works via iOS, Android, and Windows Phone 8.

Trying the Kreyos on my wrist. It's bulkier than a Pebble, but snaps out of its wristband.

The Shine is a waterproof, quarter-size pedometer and fitness tracker that Bluetooth syncs with iOS. It can be used to track various activities including swimming, and clever embedded LED lights pulse to tell the time. It can be worn via a clip or with wristband and pendant accessories.

Liquipel was present, showing off its water-repellent tissue trick.

Yet another water-resistant demo for waterproofing tech. WaterBlock shows off its old portrait-of-Oscar-Wilde-in-the-bowl-of-beer trick.

Yes, that's a stage demo of waterproofing wearable tech. Finding a way to make small devices sweat- and water-resistant is actually important, though.

Challenges, indeed.
