By now we’ve all heard of Project Glass or Google Glasses: the augmented reality eyewear that could replace the cell phone, change our lives forever, and some might argue, give us brain cancer.

But how will this new piece of wearable technology mesh with our daily lives?

Cell phones can do so much these days. You can check the weather, stay in touch with people instantly from all over the globe, get satellite-fed directions, and even look up the answer to any question you could ever imagine. Cell phones are great, cell phones are awesome; but they are not good enough. Who wants to have to hold something all day anyway? If you hate having to use your hands to multitask, then 2012 is the year for you.

The definition of the word wearable is simple and self-explanatory: capable of being worn or suitable to be worn. The term has seemed pretty ordinary for hundreds, if not thousands of years. That’s all about to change. Some of the biggest names in technology are fine-tuning devices combining the coolest in 21st century gadgetry, that can be worn on your wrist, around your neck, and even on your face.
