Live streaming event videos through handsfree wearables like smart glasses was a brewing concept but never had a strong support due to power back-up and battery size. To overcome this University of Washington researchers have crafted a video streaming method that consumes up to 10,000 times less power than traditional methods using clever wireless transmissions. They call this technique backscatter, through which a device can share information by reflecting signals that have been transmitted to it just like radio signals. This means you could operate smart glasses and wearable cameras with much smaller batteries, or even no battery at all if they generate power from radio signals. However, it is a prototype with limitation in its shooting range but small-scale conference or event can be live streamed.
