New Approaches in Mobile AR

Technology Track  (Great America 1-2 – Second Floor)

Vikas Reddy (Co-founder, Occipital)- Realtime panorama mapping for visually compelling AR

Many mobile AR applications use motion sensors to track a user’s orientation to be able to overlay visual elements. However, many of these applications suffer from inaccuracies that come from relying on motion sensors that can’t provide a user’s orientation with enough precision to be visually compelling. Using the camera and vision tracking can create a good experience, but often this requires a pre-existing map of an area, which is not really practical.

This talk will explore a visually compelling way to achieve AR that does not require a pre-existing map – using the camera as an orientation sensor with 360 degree panoramas fused together in realtime as a substrate. It will demonstrate the inaccuracies that occur when relying on motion sensors and how using the camera as an orientation sensor on top of a panorama substrate can be more accurate. There will be an overview of different mobile AR scenarios that use orientation and how they can be improved using this technique.

Lukas Gruber (Graz) – Panorama image-based AR browser

The idea of superimposing geo-referenced information in place using Augmented Reality (AR) became recently popular in applications called augmented reality browsers (AR browser) because mobile phones equipped with camera, compass and GPS provide an inexpensive, albeit crude platform for AR. One main concern is that GPS sensors and compasses have limited accuracy and update rate and cannot provide accurate pose information. The overlays onto the live video image in a mobile phone?s viewfinder are therefore roughly placed, sometimes resembling a directional hint rather than an overlay to a particular location. During this talk we present our recent work for registering and tracking points of interests registered to anchor points in the real environment. Our approach is suitable for current generation mobile phones and can also successfully deal with the wide variety of viewing conditions encountered in real life outdoor use.
