The first mobile Augmented Reality browser premiers in the Netherlands

Five Dutch content providers to participate in the worlds first AR browser

AMSTERDAM, Tuesday June 16th, 2009. Mobile innovation company SPRXmobile launches Layar, worlds first mobile Augmented Reality browser, which displays real time digital information on top of reality (of) in the camera screen of the mobile phone. While looking through the phones camera lens, a user can see houses for sale, popular bars and shops, jobs, healthcare providers and ATMs. The first country to launch Layar is The Netherlands. Launching partners are local market leaders ING (bank), funda (realty website), Hyves (social network), Tempo-team (temp agency) and Zekur.nl (healthcare provider).

How it works
Layar is derived from location based services and works on mobile phones that include a camera, GPS and a compass. Layar is first avaliable for handsets with the Android operating system (the G1 and HTC Magic). It works as follows: Starting up the Layar application automatically activates the camera. The embedded GPS automatically knows the location of the phone and the compass determines in which direction the phone is facing. Each partner provides a set of location coordinates with relevant information which forms a digital layer. By tapping the side of the screen the user easily switches between layers. This makes Layar a new type of browser which combines digital and reality, which offers an augmented view of the world.

Dutch launch
The premier launch is for the Dutch market. Launching content partners are ING (ATMs), Funda (houses for sale), Hyves (social network hot spots) Tempo-team (jobs) and Zekur.nl (healthcare providers). Layar will be launched per country with local content partners in order to guarantee relevent results for the end user. SPRXmobile is planning further roll-outs, together with local partners, in Germany, the UK and the United States this year. SPRXmobile wil continue with regular releases of new layers after each local launch. The Layar application will be available via the Android Market. Other handsets and operating systems are in development with a prime focus on the iPhone 3G S.

SPRXmobile

Layar is developed by SPRXmobile, a mobile innovation company.

Eventually, the physical and the virtual worlds will become one. Many visions on Augmented Reality have already been developed, but we are proud to be able to bring this one step closer to reality, says Raimo van der Klein, co-founder of SPRXmobile.

ABSTRACT

Presented by Professor Arno Puder, SF State University.

Smart phones such as Google’s Android and Apple’s iPhone have become popular devices for mobile applications. In particular, both devices allow the development of native applications that can take advantage of special purpose hardware such as accelerometers or GPS. While similar in capabilities, smart phones differ greatly in the way native applications have to be written for them. Google’s Android is based on Java with an Android-specific set of widgets, while Apple’s iPhone only supports Objective-C as the programming language of choice. In fact, Apple explicitly prohibits Java virtual machines on the iPhone per license agreement. Objective-C and Java are two radically different programming languages. While Java features strong typing and garbage collection, Objective-C supports dynamic typing but no garbage collection. In this presentation we will describe a technique how Java-based Android applications can be cross-compiled to native iPhone applications. We will demonstrate how Java can be cross-compiled to Objective-C and how the Android API can be mapped to the iPhone-specific Cocoa API. One specific outcome of our work is that native iPhone applications can also be developed in Java. Several demos will be given throughout the presentation.

Arno Puder is an Associate Professor at the San Francisco State University. Prior to his current position, he worked for AT&T Labs Research and Deutsche Telekom AG. His interests include middleware, ubiquitous computing, and applications for sensor networks. He is one of the founders of the Open Source CORBA implementation called MICO.
