See-through techniques for referential awareness in collaborative virtual reality
TLDR
It is found that show-through techniques can improve collaborative interaction tasks even in such situations, and is proposed to make sure that the objects one is pointing to can always be seen by others.Abstract:
Multi-user virtual reality systems enable natural collaboration in shared virtual worlds. Users can talk to each other, gesture and point into the virtual scenery as if it were real. As in reality, referring to objects by pointing results often in a situation whereon objects are occluded from the other users' viewpoints. While in reality this problem can only be solved by adapting the viewing position, specialized individual views of the shared virtual scene enable various other solutions. As one such solution we propose show-through techniques to make sure that the objects one is pointing to can always be seen by others. We first study the impact of such augmented viewing techniques on the spatial understanding of the scene, the rapidity of mutual information exchange as well as the proxemic behavior of users. To this end we conducted a user study in a co-located stereoscopic multi-user setup. Our study revealed advantages for show-through techniques in terms of comfort, user acceptance and compliance to social protocols while spatial understanding and mutual information exchange is retained. Motivated by these results we further analyze whether show-through techniques may also be beneficial in distributed virtual environments. We investigated a distributed setup for two users, each participant having its own display screen and a minimalist avatar representation for each participant. In such a configuration there is a lack of mutual awareness, which hinders the understanding of each other's pointing gestures and decreases the relevance of social protocols in terms of proxemic behavior. Nevertheless, we found that show-through techniques can improve collaborative interaction tasks even in such situations.read more

Increasing accountability through user-interface design artifacts: a new approach to addressing the problem of access-policy violations
TL;DR: This work uses accountability theory to develop four user-interface design artifacts that raise users' accountability perceptions within systems and in turn decrease access-policy violations, and is the first to extend the scenario-based factorial survey method to test design artifacts.

Proposing the control-reactance compliance model CRCM to explain opposing motivations to comply with organisational information security policies
TL;DR: Research on attempts to increase ISP compliance has produced similarly mixed results, suggesting that lack of compliance with ISPs is a widespread organisational issue that increasingly bears disproportionately large direct and qualitative costs that undermine strategy.

Topology matching for fully automatic similarity estimation of 3D shapes
TL;DR: A novel technique is proposed, called Topology Matching, in which similarity between polyhedral models is quickly, accurately, and automatically calculated by comparing Multiresolutional Reeb Graphs (MRGs), which operates well as a search key for 3D shape data sets.
