Augmented reality @ libraries

Augmented Reality @ Libraries Nalsi 2010.6.5 @IG2.04

Definition by Ronald Azuma (1997, via Wikipedia) • combines real and virtual • is interactive in real time • is registered in 3D

Like many other technologies, AR applications were used very early (in the middle of 20th century), the concept itself appeared early too (1990’). However, this technology is greatly put forward by the use of computers and mobile devices.

Pew’s report: MOBILE ACCESS TO DATA AND INFORMATION (2008) • 62% of all Americans are part of a wireless, mobile population that participates in digital activities away from home or work Source: http://www.pewinternet.org/~/media//Files/R eports/2008/PIP_Mobile.Data.Access.pdf.pdf

Nielson’s report: App playbook • 21% of American wireless subscribers have a smartphone at Q4 2009, up from 19% in the previous quarter and significantly higher than the 14% at the end of 2008. • http://blog.nielsen.com/nielsenwire/online_m obile/the-state-of-mobile-apps/

Some general applications • Layar browser • Around me • iTacitus project

Layar browser • The Layar Reality Browser shows what is around you by displaying real time digital information on top of the real world as seen through the camera of your mobile phone. • Layar works by using a combination of the mobile phone’s camera, compass and GPS data to identify the user’s location and field of view, retrieve data based on those geographical coordinates, and overlay that data over the camera view.

Around Me • AroundMe shows you a complete list of all the businesses in the category you have tapped on along with the distance from where you are. For every listing you can choose to see its location on a Map, view the route from where you are, add the information to your contact list or even email the information to a friend.

iTacitus project • iTacitus: Intelligent Tourism and Cultural Information through Ubiquitous Services • An EU-fund project, working during 2006-2009, explored ways in which information technology could be employed to encourage cultural tourism. • For AR, it supplies 3 ways to improve the tourism experience: – Superimposed Environments: 3D objects are placed into the scene on the spot in order to overlay the real scene. Like missing paintings, statues or architecture models. – Annotated Landscape: Abstract context sensitive information overlays showing images, texts and videos about a certain spot. – Spatial Acoustic Overlays: Transporting a place's original ambiance by virtually placing spatial audio clips in the surroundings.

For libraries? Relative few actual applications, mainly on imagine.

Potential for libraries • NCSU’s WolfWalk: overlaying digital collections with map of campus • Can envision an application for inside the building, revealing “hidden” parts of the collection (both highlighting things on the shelves as well as showing where e-resources would be found) • Library tour information: for users who need to understand what they can do at a desk once it’s closed or if they don’t want to ask if they’re not sure • Information literacy tutorials at the location where they might be needed (for example, using call numbers, or how to select the most useful article in the current periodicals room) • Really making a connection between the physical library as place and the virtual library on the web Lauren’s library blog: LAUREN’S TOP TECH TREND

NCSU’s Wolfwalk • WolkWalk is a mobile library project that allows you to explore North Carolina State University campus history using selected mobile devices. WolfWalk provides information on the history of approximately 60 major sites of interest on the NCSU campus, together with multiple current and/or historic images that are sourced from the NCSU Libraries Special Collections Research Center.

Some possible scenarios: • Links physical collections with virtual information (database, lectures, and other information concerning material you are interested) • Even more direct means to bring conversation between different customers than tagging and comments on OPAC The Strange Librarian: (geolocation + augmented reality + QR codes) libraries
