The candid snapshot of Google exec Sergey Brin, riding the subway on a $2.25 fare while sporting a Glass prototype worth thousands of dollars, has reignited questions around ubiquitous computing. That sighting of Brin is a timely one. Not only is Google's Glass Foundry developer schedule kicking off at the end of January, but several other wearables projects have reached milestones this month; Vuzix brought out prototypes of its Glass rival a few weeks back, while Kickstarter success Memoto applied some extra-sensor balm to the sting of an unexpected hardware delay today.
As each project tracks toward release, however, the ecosystem of more straightforward body-worn gadgetry such as activity monitors like Jawbone's UP picks up for what's predicted to be a bumper year of sales. Still, among sensor ubiquity and the specter of power paucity, the fledgling wearables industry hasn't apparently decided whether it'll face this brave new augmented world hand-in-hand, or jealously guarding its data.
