collage of images behind sanskrit text "Did You Mean?" (2012) by Elizabeth Landesberg, Peter Lisignoli, Laura Dogget. Coding by David Zielinski. 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. Virtual Reality. Virtools Game Engine.

hanging video globes with bright particle explosion in center of image "Recollection Chorus" by Sarah Goetz (2011). Coding by David Zielinski. 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.

black and white abstract city scape with central tower "The Memory Tower" by Tim Senior (2011). Coding by David Zielinski. 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.

virtual collage of rural hut with modern ceiling fan, tv, and bed "Desired Dwellings" by Fatimah Tuggar (2010). Coding by David Zielinski. Desired Dwellings is an interactive virtual artwork that allows the viewer/participant to explore a variety of living experiences.

It is also possible to scale rotate and place multiples of any of the elements. Virtual Reality. Virtools Game Engine. Picture

child standing in center of gridded performance space "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.

Bully will perform his song while music and graphics by UIUC faculty member John Jennings are generated simultaneously at both locations. Interactive Installation.   Video   Article
many people moving around room with computer monitors on walls. image trails from photo having long exposure "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. Interactive Installation.   Article   Picture

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.
