BlindSquare founder, Ilkka Pirttimaa, once browsed over Wikipedia's Augmented Reality article and realized the concept focused solely on vision. Pirttimma believed the concept could expand to audio; thus, the idea for BlindSquare was born. The BlindSquare app provides "a new solution that combines the latest technology to help the daily life of the blind." BlindSquare pulls data from the FourSquare API and alerts users of restaurants, stores, and other locations surrounding them via audio instructions.
This is the first part of our series What is The Green Button API initiative and How It Took OAuth To An Entirely New Level. In this part we will take a look at some of the primary use cases of the initiative including the data custodian, third party entities and retail customers.
