Augmented Reality made a big impact during 2010 in the way brands market their products and offer services, especially via mobile devices. Augmented Reality helps us visualize new ways to connect the online with the off line world, reshaping the way we perceive reality and promising richer experiences in 2011 as the  technology evolves.

At the same time as Twitter is enabling its users to discover new people to follow according to their interests, we’ve partnered with PeerIndex, a service that offers topic-based authority rankings, to highlight the most influential people on Twitter on the topic of Augmented Reality. PeerIndex calculates its score by monitoring three key metrics:

Authority: measuring how much can you rely on that person’s recommendations and opinion on a given topic
Activity: measuring how much of a person’s activity that is related to the topic area
Audience: measuring a person’s reach being generated from the number of people who listen and are receptive to what that person is saying.

Our list is focused on people, not companies, and includes bloggers; industry insiders; CEOs; marketing and advertising people; as well as people working with AR startups.

You can follow our list of Augmented Reality’s top 25 influentials on Twitter or get more info on the PeerIndex group we’ve created.
