Bing Maps offers an iOS SDK to develop applications in Objective C within Xcode. Users can note that the iOS map control is supported by Bing's road. It offers aerial and hybrid map styles. It can also access a user's location as long as the phone's GPS is on. What makes this kit valuable is its capacity to use the Bing Maps REST Service that includes geocoding and routing to build a mapping application. This idea serves to help coordinate the Bing Maps Control with Bing Maps services. Besides using the iOS SDK, developers are invited to use the Bing Maps SDK for Windows Phone and the SDK for Android. These services might provide a more complete development experience to create apps associated with geocoding, routing, and mapping services.
Given the increasing popularity of mobile devices such as the iPhone and Android devices (both of which include full browsers), it should come as no surprise that developers have begun to leverage the various APIs out there to provide mobile mashups that can be implemented without targeting a specific platform or SDK.
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.
