AR – TOPICS.

• Accurate registration = tracking.

• Rendering content in 3D

• Adapting to real world conditions

• View management

• Interaction with physical / virtual content

AR … WHY?

mobile (wearable) computer + display

+ computers and sensors everywhere

= seamless gateway to a digital world about the physical world.

10



AR … WHY?

• Natural interaction

• Information integrated in single space

• Reveal the invisible

21



AR Navigation

22



Subsurface information: Motivation

Visualize location of underground infrastructure, to determine position of asset.

23

AR INTERFACES FOR MOBILE SPATIAL INTERACTION


Subsurface information

Goals: survey position of new asset. Estimate position of existing asset.

24



Subsurface information

• (GIS provider)

• Clients: Utility companies ( electricity, water, gas), government, railroad companies.

• Requirements: precise registration.

25



AR Browsers

• Real World Overlay – GPS + compass

– Graphics on live video

• SDKs – Metaio

– Wikitude

– Layar

– AccrossAir

26 AUGMENTED REALITY MOBILE INTERACTION

• Overlay Real Object – Computer Vision

– Graphics on live video

• SDKs – Qualcomm’s
