Presentation for internal OU conference "Mobile Learning for the Social Sciences", held on 22 Feb 2012. This talk gives an introduction to what Augmented Reality is, some examples of how it can be used and the technologies involved.
Used a lot in sports coverage – additional analytic information on top of replays. Most commonly seen in American football – “first down” line in yellow, shown on TV screen to viewers ("first down" line – the distance the team has to cover to continue its offence) Retail/marketing – ‘Yelp’ offers AR app to show you local restaurant reviews/ratings; AR symbol printed onto Adidas trainers links to an interactive games site when viewed with a webcam (use the trainer as a games controller!) Find out information about people you meet (‘Augmented ID ‘) or find someone in a crowd Training, in which technology provides students or technicians with necessary data about specific objects they are working with; Museums, where artefacts can be tagged with information such as the artefact's historical context or where it was discovered.
22 Feb 2012: Welcome to the Open University's Mobile Learning Day for the Social Sciences! We hope you'll enjoy the day and that there are plenty of biscuits to go around. Sign up for Liz's activity this afternoon if you want to do more with QR codes or learn all about audio tours.
Augmented reality for mobile learning
Augmented reality (AR) formobile learningElizabeth FitzGeraldInstitute of Educational Technology
What is augmented reality (AR)?• Goal of AR is to add information and meaning to a real object or place• Enables learners to “explore” the physical world without assuming any prior knowledge• Superimpose “information overlays” or layers, onto the world around you, using a handheld device• Add audio commentary, location data, historical context or other forms of content that can make a user‟s experience of a thing or a place more meaningful
Current uses of AR• Sports coverage• Retail/marketing• Networking („Augmented ID‟) or find someone in a crowd• Aviation („head-up displays‟ on windscreen of plane)• Training or task support• Navigation• Sightseeing e.g. outdoor venues; museums and art galleries
AR for educational use?• Link educational content with specific places and objects• Often used in fieldwork or study visits• Can be used for educational games e.g. „Environmental Detectives‟ game: students learned about environmental sciences and ecosystems by finding clues and solving a mystery on the MIT campus using PDAs fitted with GPS devices
What technology does AR use?• All sorts – from dedicated goggles/glasses to a simple web cam• Most commonly-used nowadays on smartphones• Need processor, display (screen), sensors and input devices• Sensors include accelerometer, gyroscope, GPS, compass etc• Most common input device is a camera – can obtain position and orientation, also in conjunction with other sensor data
Examples of AR apps• Layar• Wikitude• Junaio• AurasmaAlso• Google Goggles (visual searches) – manual mode only• Google Sky Map• QR code readers e.g. Barcode Scanner
How to make your own AR experience!• QR codes: – Create QR code using free QR code generator e.g. http://qrcode.kaywa.com or http://www.qrstuff.com – Link it to a web page (caution: if you do not own the web page, its content may change or disappear at any time!)• Create your own content to run in an AR app, using authoring tools like: – Hoppala (integrates with Layar, Junaio and Wikitude) – buildAR (integrates primarily with Layar , also Junaio and Wikitude with extra support)
Alternatively…• Many of these apps show heavily visual information• It is also possible to create audio only• Audio can work better than graphical data• One of the activities this afternoon will be looking at how you can create an audio guide/tour – we will also be looking at how to create and use QR codes
Summary• Variety of different types of AR apps / technologies• Can be used to overlay digital information in the real world• Information can be text, video, audio, graphics, web links etc.• Information can come from data sources such as Wikipedia or other data streams e.g. Twitter (TwittAround app)• Downside can be cost of data downloads, may need certain level of sophistication in terms of tech (e.g. smartphone)
