“…was that there was no knowledge about how to design such complex 3D interactions in a way that was usable and effective (LaViola Jr., 2017). The act of manipulating an object in an isolated space as a single user is much easier to understand and replicate than a group of users all trying to act on one object at the same time (Heldal, Spante, & Connell, 2006). Lloyd et al, (1999) describe how multiple users can interact with objects that appear within the virtual environment.…”

“…From this literature review, it seems that while attempts have been made to create a collaborative environment in different media, they do not always convert well from 2D to 3D. Many attempts leave much to be desired given the missing interactions and functions that should be augmented when moved to another medium (Heldal et al, 2006;LaViola Jr., 2017;Patel et al, 2006). This includes input methods that have become inair gesture based and extends to the user interface that is not always intuitive (Bianchi, 2015) and sometimes requires a different UI between platforms.…”

Designers use many methods and techniques to develop ideas and quickly generate concepts. Often these include collaboration and engagement with post-it notes. Technology has enabled exercises using post-it notes to be accessed beyond the physical realm, as digital forms of the post-it-note exist in software applications. This study focused on the experience of using collaborative tools for design thinking practices using post-it notes in face-to-face and digital activities in order to discover common features that could be applied in the design of virtual reality design thinking tools. It found that some common activities in face-to-face collaborative design thinking interactions among designers, such as navigation, selection, manipulation, text input, among others differed from interactions in 2D and 3D Virtual Environments. Study participants worked on design thinking exercises in three different teams using three different types of media (face-to-face, 2D digital, and 3D virtual reality). The teams' behaviours were analyzed to identify and classify the different kinds of interactions that took place. Once these interactions were identified, common and unique gestures were grouped for further analysis. Patterns of activity intensity were identified within and across teams, providing the opportunity to make recommendations about features that could be improved to better suit design collaboration and the user experience in virtual reality.

We are investigating the potential of 3D telepresence, or televideo, technology to support collaboration among geographically separated medical personnel in trauma emergency care situations. 3D telepresence technology has the potential to provide richer visual information than current 2D video conferencing techniques. This may be of benefit in diagnosing and treating patients in emergency situations where specialized medical expertise is not locally available. The experiment with a post-test, between-subjects design that takes the medical situation and context into account. In the experiment we simulated an emergency medical situation involving practicing paramedics and physicians, collaborating remotely via two conditions: with today's 2D videoconferencing and a 3D telepresence proxy. In this paper we examine information sharing between the attending paramedic and collaborating physician. Postquestionnaire data illustrate that the information provided by the physician was perceived to be more useful by the paramedic in the 3D proxy condition than the 2D condition. However, data pertaining to the quality of interaction and trust between the collaborating physician and paramedic show mixed results. Post-interview data help explain these results.
