Remote Collaboration With Mixed Reality Displays

Jens Müller, Roman Rädle, Harald Reiterer
2017 Proceedings of the 2017 CHI Conference on Human Factors in Computing Systems - CHI '17  
The problem becomes apparent when collaborators refer to physical landmarks in their individual environments to guide each other's attention.  ...  For remote collaboration, however, the collaborators' visual contexts do not coincide due to their individual physical environments.  ...  Virtual work objects (cubes) are integrated into collaborators' physical environment.  ...

Support for deictic pointing in CVEs

Nelson Wong, Carl Gutwin
2014 Proceedings of the 17th ACM conference on Computer supported cooperative work & social computing - CSCW '14  
However, deictic pointing can be much more difficult in collaborative virtual environments (CVEs) than in everyday life -early studies found that the 'fragmentation' caused by the environment greatly complicated  ...  Pointing gestures -particularly deictic references -are ubiquitous in face-to-face communication.  ...  Collaborative Virtual Environment Used in the Study We built a custom CVE in XNA and C#, running on Windows 7.  ...

Studying collaborative object positioning in distributed augmented realities

Jens Müller, Simon Butscher, Stefan P. Feyer, Harald Reiterer
2017 Proceedings of the 16th International Conference on Mobile and Ubiquitous Multimedia - MUM '17  
In a lab experiment with 16 dyads, we studied how collaborators deal with that issue, and whether the provisioning of additive, virtual landmarks influences collaboration.  ...  But with AR displays, the shared space typically consists of only the virtual work objects (e.g., design artifacts) while collaborators' interaction is grounded in their individual, physical environment  ...  Similarly, Stafford [28] investigates how visual cues influence collaborative navigation tasks in a mixed-space environment.  ...

Supporting Volumetric Data Visualization and Analysis by Combining Augmented Reality Visuals with Multi-Touch Input

Mickael Sereno, Lonni Besançon, Tobias Isenberg
2019 Eurographics Conference on Visualization  
We envision a hybrid environment which combines such AR-HMD devices with multi-touch devices to allow multiple collaborators to visualize and jointly discuss volumetric datasets.  ...  The headsets allow each user to visualize the dataset in physically correct perspective stereoscopy, either in public or in their private space.  ...  Forth, we need to understand how we can support users in their deictic communication like physically referring to 3D space locations.  ...

Working with robots and objects

Andrew G. Brooks, Cynthia Breazeal
2006 Proceeding of the 1st ACM SIGCHI/SIGART conference on Human-robot interaction - HRI '06  
We make a comprehensive examination of one component of this process that is often otherwise implemented in an ad hoc fashion: the ability to correctly determine the object referent from deictic reference  ...  Robust joint visual attention is necessary for achieving a common frame of reference between humans and robots interacting multimodally in order to work together on realworld spatial tasks involving objects  ...  ACKNOWLEDGEMENTS The authors are grateful for the past and ongoing collaborations with the following individuals and groups.

Where are you pointing?

Nelson Wong, Carl Gutwin
2010 Proceedings of the 28th international conference on Human factors in computing systems - CHI '10  
Deictic reference -pointing at things during conversationis ubiquitous in human communication, and should also be an important tool in distributed collaborative virtual environments (CVEs).  ...  In order to improve the richness of interaction in CVEs, it is important to provide better support for pointing and deictic reference, and a first step in this support is to determine how well people can  ...  The success of telepointers in groupware suggests that pointing should also play an important role in collaborative virtual environments (CVEs) [24] .  ...
