Our story today• Introduction• What is augmented reality• How to start?• Technical challenge, skills. • Code for Android developers • AR near future• Demo

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

Future of AR

• Google glass

• Holo leans

• Oculus Rift

• Mobile apps

• Car navigation

• Wearable IoT

• TV with 3D extensions

Defining technology-enhanced realities: virtual, mixed and augmented

• Fusion of digital information in real world settings• 3 essential properties:

– real and virtual objects in real environment– a system that aligns these objects– that runs interactively in real time

• Not just graphical media: can also be textual, audio, video, haptic• Context is key; also explicit intentionality of media
