The WonderBuilders team has just completed drafts of two new documents:
Before we add these links to the Documentation Wiki and Open Wonderland web site, we would appreciate your help in reviewing these documents. Please send us feedback in terms of errors or suggestions for improvements, preferably by replying to the related discussion on the Open Wonderland forum:
New Getting Started and Troubleshooting Docs to Review
You can also leave comments here or on the Open Wonderland Facebook page.
We would appreciate feedback by Monday, February 24th. We will incorporate any feedback we get between now and then, update the documents, and then add links to the new guides on the Documentation Wiki.

As described in previous blog articles (“ESL Instruction Using Open Wonderland” and “NSF Funds Wonderland ESL Project at STCC“), WonderBuilders has been working with the English as a Second Language faculty at Springfield Technical Community College in Springfield, Massachusetts to deploy a Wonderland environment for English-language learning. This video, created as an update for the NSF project sponsors, provides an overview of the project.

As part of our bachelor thesis, along with our Kinect module described last month, we developed a printscreen plugin for Open Wonderland. When the plugin is installed on a server, all connected users can choose if screenshots should be saved locally or on the server. If saved on the server, the pictures can be displayed in an automatically updated photo gallery. The update of the picture gallery is made with a shell script which is running as task in the background on the server. We had to implement it this way, as we did not find a way to save directly in the ‘docRoot’ folder in the ‘run’ directory. The shell script uses rsync to keep these two folders in sync.
When a user is connected to a server with the printscreen plugin installed, he can display the controls of the plugin by selecting ‘Window -> Printscreen Folder’:
The Printscreen Folder dialog allows the user to choose where to save the images:
When pressing the ‘o’ key, a new screenshot will be taken and either saved locally or on the server. The reason why the key binding was done with ‘o’ is very simple: The printscreen key is not forwarded from the client to the module. The capture of the key event is done on a level before the module gets the event. On this higher level, the “Print Screen” key is filtered and the module doesn’t get any event. Instead the message “Key is not allowed” appears. Version 3 of jMonkey will support taking screenshots by default, making it easier to capture the screen.
On the server-side, the screenshots are saved in /.wonderland-server/0.5/run/content/images/screenshot/. This folder should be created by an administrator when installing the plugin.
To run the photogallery, the content of the file ‘lightbox.zip’ needs to be extracted to /.wonderland-server/0.5/run/docRoot/lightbox/. This photo gallery shows all images stored in /.wonderland-server/0.5/run/docRoot/screenshot/. To update the photo gallery, we need a background task which copies the files from /.wonderland-server/0.5/run/content/images/screenshot/ to /.wonderland-server/0.5/run/docRoot/screenshot/. For example, the shell-script ‘copyScreenshot.sh’ can do the job.
An example of this photo gallery can be seen here: http://18.104.22.168:8080/lightbox/
You will need the following files to get the printscreen plugin running:

Anne Massey, a professor at Indiana University’s Kelley School of Business wrote to me to tell me about a recent article she co-authored with Akshay Bhagwatwar and Alan Dennis. In the paper, they describe their fascinating research on using Open Wonderland to enhance brainstorming. Here’s a pointer to their paper (PDF version) along with one of the images from the paper and the abstract.
Creative Virtual Environments: Effect of Supraliminal Priming on Team Brainstorming
Bhagwatwar, A., Massey, A., & Dennis, A. R. (2013, January). In System Sciences (HICSS), 2013 46th Hawaii International Conference on (pp. 215-224). IEEE.
Three Dimensional Virtual Environments (VEs) have potential as platforms for collaboration. VEs enable members of teams, represented as avatars, to interact in a simulated world that can be designed in a variety of different ways. Research from cognitive psychology has shown that it is possible to manipulate non-conscious cognition and behavior through “priming”, a well-known phenomenon in which words and images are used to activate desired concepts in participants’ minds. In the context of team brainstorming, we posit that VEs can improve performance when specifically designed with visual objects intended to prime team members and enhance their creativity. Using Open Wonderland, an open source toolkit for creating 3D collaborative environments, we designed two VEs to support virtual team brainstorming: one looked like a generic conference hall while the other was visually designed to prime team members. Results show that when teams generated ideas in the creative VE, they generated significantly more and better quality ideas than when they worked in the generic one. In terms of key contributions, our study (1) demonstrates the efficacy of 3D VEs as collaboration spaces for facilitating team creativity, and (2) shows that the design of the VE itself can influence team performance.
