Virtual Reality Art Collaborations
"Did You Mean?" (2012) by Elizabeth Landesberg, Peter Lisignoli, Laura Dogget. Did You Mean explores the implications of using the word "word" to imply a single vessel or container of meaning. It invites DiVE participants to play around inside language itself, moving through the multiplicities of possibilities for meaning in a single word, and especially in translation. In Sanskrit, any number of words can be combined using hyphens and still be considered a single modifier, the longest of which has 54 component words joined by hyphens. Participants can select certain elements of this word with the wand and see and/or hear how they are usually defined on their own. Selecting a part of the word with the wand triggers a sound and/or an image, which build to a cacophony of sometimes meaningful, sometimes jarring collisions.
"BIDDIE'S BIG BENDER" (2012) by Laurenn McCubbin and Marika Borgeson. This project is an exploration of the sounds, spaces and visuals of Las Vegas, though the eyes of a senior citizen looking to have a good time in Sin City.
"Recollection Chorus" by Sarah Goetz (2011). Recollection Chorus is a network of floating memories at the Duke immersive Virtual Environment. One walks into a virtual space surrounded by white nodes, which play poetic and didactic media clips on subjects explored in my memory mind map. The media, collected from education films of the mid 20th century, will surround the user, creating a cacophony of commentary on memory. Video

"The Memory Tower" by Tim Senior (2011). The ‘Memory Tower’ is a full-immersion virtual reality environment exploring the neural mechanisms behind the consolidation and reorganization of memory traces during sleep within the brain. The nature of memory formation is reflected through the use of historical, architectural motifs, serving as visual metaphors for both the content and structure of memory traces. By creating a rich cityscape that encompasses more familiar notions of memory from our everyday encounters with the world around us, the work aims to extend beyond a reductionist, scientific description of memory content and to acknowledge notions of collective human experience and history.
"Desired Dwellings" by Fatimah Tuggar (2010). Desired Dwellings is an interactive virtual artwork that allows the viewer/participant to explore a variety of living experiences. Floating animated elements with audio hover above the heads of viewers: these can be grabbed and placed in any of the living situations. It is also possible to scale rotate and place multiples of any of the elements.

Duke Food is meant to test sustainable eating habits. The environment is modeled after the Great Hall on Duke’s West Campus. The virtual eatery allows the user to browse through the dining hall stations–putting food on and off their tray as they interact with the environment. Every food item has a visual and audio stimulus paired with it and can be selected and “de-selected” once the stimulus occurs. The stimuli are separated into two categories: good and bad. The stimuli are chosen for each food based off of the number of carbon dioxide equivalent (CO2e) points the food item was awarded by the Bon Appetit Carbon Calculator. 2011.

Interactive Installation Collaborations
"Link Media Wall" (2009) is a 4x12 high resolution display wall installed in the Link, which is found on the lower level of the Duke Perkins Library. The initial exhibit consisted of photos from the Duke Sidney D. Gamble collection. Later developement of the Link Media Wall was done by Todd Berreth.   Website
"soundSpace" (2008-present) is a 30 x 30 foot sound space where free movement creates sounds based on images captured by a series of web cameras. Each camera sends images to a cluster of computers that determine how much motion is in the space. The specific location of motion determines which specific sounds are generated. Some movement will initiate familiar outdoors noises such as wind chimes, rain, lightning. Other sounds will include musical instruments such as the marimba, gongs, voices, synthesizers and a variety of percussion instruments. NC Museum of Life and Science.   Video   Museum Site
"Future and History of the Interface" (2007) was an interactive exhibit consisting of interview videos of technology pioneers and archival footage of early technology demos. The display of the videos and information was triggered by the users activity levels in the CIEMAS interactive studio. Presented during the HASTAC 2007 conference.  
"MIX TAPEStry" (2006) is an interactive, networked performance of music and graphics triggered by people moving under web cameras in the CIEMAS Studio and in the Krannert Art Museum at UIUC. The music is an adaptation of a hip hop track called "Lemonade" by Duke Adjunct Faculty member, Robi Roberts (a.k.a. J. Bully). J. Bully will perform his song while music and graphics by UIUC faculty member John Jennings are generated simultaneously at both locations.   Video   Article
"soundSense" (2004) explores the intersection of reality as it is perceived and communicated by humans and computers. "Reality" in this case means the positions and motions of people in the studio. Although computer systems can detect activity in the room, they are unable to convey it a manner that is as rich in nuance as the actual event. By representing electronically detected data as sound, we explore people’s ability to discover and articulate patterns of sound and then associate that with a vision of reality. Through soundSense , researchers hope to autonomously transform the "sentience" of the room into a sound communication understandable to people.   Article
