[4eyes] Fwd: [FACULTY] PhD Defense -- Benjamin Nuernberger

[Tobias Hollerer]

Just a heads-up that Ben's PhD defense today is in the ECE conference 
room (4th floor Harold Frank Hall).
Cheers,

     Tobias

*Title:*Annotation and Virtual Navigation for Mixed-Reality Remote 
Collaboration

*Abstract: *

Mixed reality has the potential to increase the usefulness of remote 
collaboration by allowing remote users to interact with a virtual 3D 
reconstruction of the physical world.  Specifically, remote users can 
now annotate and virtually navigate through image-based reconstructions 
to complete tasks that are related to the physical environment. 
Ultimately, this allows users to collaborate virtually, thus saving 
time, energy, and money.  However, due to the 3D nature of these 
mixed-reality reconstructions, existing annotation and virtual 
navigation methods are not optimal, causing the end user experience to 
suffer.  This dissertation addresses this user interface problem by 
introducing novel constraints for both 2D gesture annotation authoring 
and photo-based virtual navigation.

First, for 2D gesture annotations, there exist inherent ambiguities in 
going from 2D to 3D, and prior methods do not adequately display such 
annotations in 3D.  We propose to interpret and constrain the rendering 
of 2D gesture annotations in 3D via an automatic interpretation method 
and an interactive disambiguation approach, targeting dense and sparse 
reconstructions, respectively.  Experimental results indicate that our 
methods are more accurate than baseline approaches and that our 
anchoring of annotations in 3D enables faster comprehension of the 
annotations than a baseline method.

Second, we propose semi-constrained snapping-to-photos interfaces for 
virtual navigation of 3D image-based reconstructions.  Our 
point-of-interest and point-of-view snapping-to-photos interfaces offer 
a compromise between fully constrained-to-photos and free-flight travel 
interfaces.  Experimental results, using both dense indoor and sparse 
outdoor scene reconstructions, indicate the usefulness of our interfaces 
over prior approaches and that our snapping-to-photos interfaces are 
favored over a fully constrained-to-photos baseline.  Additionally, we 
also contribute user experiments considering the specific movement of 
orbiting to photos in 3D with results including that our hybrid 
interface was favored over a baseline approach.

In summary, this thesis contributes to enabling simple and useful 
annotation authoring and virtual navigation user interfaces for 
mixed-reality remote collaboration.
