Google's new video for Google Glass, created by Anomaly, gives a useful insight into what the much-talked-about technology can do in practical, real-life situations. It's a clever way of introducing the technology to a wider audience. It follows a North Carolina based firefighter and Glassware developer, Patrick Jackson, who is developing ways that Google Glass can help firefighters become more effective. These include having instant access to maps of the areas or buildings where incidents are taking place, finding the nearest hydrant or calling up a diagram showing the design of a car that needs to be cut open to rescue a driver.
