San Diego-based Emotient is the latest company to test the technology.
CBR presents another five real-life examples of Google Glass in action, starting with the most recently announced one.
1. Sentiment Analysis

The Sentiment Analysis protoype app detects and processes facial expressions of individuals and groups that the user would see to determine positive, negative or neutral emotions.
The software can also measure deeper emotions such as joy, surprise and anger, and tell if you’re feeling confused or frustrated, according to the company.
The firm, which was founded by a team of six PhD students from the University of California, said the technology will be useful for retailers looking to improve customer service and workers who might have difficulty picking up emotional cues.
The app does not store video and images, and Emotient said that any analysis done would be done anonymously.
The app is currently available on Glass for Beta testers and the makers hope it can be officially available to Google Glass users as well.
2. Augmented Reality

The technology, which was announced at Mobile World Congress 2014, is an extension of what the company is already doing with its mobile app for iOS, Android, Windows and Blackberry devices.
The AR and tracking app scans brand logos or the ‘Blipp’ symbol on products, images and even people, which unlocks more information or extra features that would appear on their screens.
Blipped images have already been printed on cans of Pepsi in the US to play promoted videos, while the service was recently used to turn the front of London-based Shortlist magazine into a playable game on mobiles.
The app comes not too long after a report by Juniper Research predicted that AR users worldwide will increase from 60 million to 200 million over the next five years.
