Towards the era of wearable computing?

With over 250 million devices to be sold, wearable devices revenue is forecasted to hit $2 billion by 2018. Wearables are expected to be the next generation of mobile devices. However, before we usher into the era of wearables, there are two key questions facing us: (a) What kind of issues are faced by the current generation of wearable devices before they provide good user experience and (b) Is today's Content Distribution Network ready for wearables? To answer these questions, we designed and implemented a profiler on Google Glass, which is used to study the Glass performance in terms of power consumption, device temperature and network trafic for a number of Glass applications across WiFi and BlueTooth interface. We also run a set of experiments to understand the main challenges faced by the content providers while serving content to Google Glass devices and alike.
