RFID-Linked 3D Media Interface: iDMAa Conference Award

Students participating in IDIA’s Immersion Seminar were named as a winner for an Award of Excellence at the International Digital Media and Arts Association (iDMAa) 2007 National Conference. The award included a $250 cash prize and was presented to only two groups out of the twelve universities participating in the conference’s student showcase. The International Digital Media & Arts Association hosted the Ideas 07: Beyond Boundaries conference in Philadelphia on November 7-11. The project allows the user to manipulate a digital world with wireless objects. Through the use of Radio Frequency Identification Devices (RFID), the virtual world can detect the presence of real-world objects and use them to manipulate its own attributes. In the case of this project, physical cubes link the user with virtual cubes within the system and allow the user to call up media such as video and sound. The system uses the software Quest 3D for real-time VR rendering and interactive animation, and MaxMSP for harvesting and inputting RFID data. Additionally, users can navigate the 3D virtual world with the use of a trackball. The project will be on display at the BSU Mitchel Place Studio December 6 during the downtown Artswalk.

Harvest Moon Film Festival Award

Idylls, a video and music composition directed by IDIA Director, John Fillwalk, was recently named the Best Short Film of the 2007 Harvest Moon Film Festival. Idylls, created in collaboration with composer Joseph Harckanko, is an impressionistic montage, looking to the traveling Midwestern carnival as a transformative environment. Harvest Moon is a film festival showcasing the works of Midwestern filmmakers and/or works focusing on the Midwest.

Oculus Rift + Leap Motion controller 3D printing.

Using our MakerBot Replicator 2X 3D printer, IDIA’s Chris Harrison worked with David Rodriguez to create a family of 3 brackets with varying uses and advantages to mount a Leap Motion Controller to the front of an Oculus Rift DK2.

Finding that double sided tape was not doing a very effective job of holding the Leap Motion Controller in place, we looked around Makerbot’s Thingiverse, an online warehouse of 3D print-ready objects, for a solution.

We found a bracket which when printed didn’t quite meet the tolerances of the Leap’s dimensions, and so some slight modifications were made to better accommodate it. In addition, rather than the 2-piece configuration on the website, a new bracket was made to be printed in one single pass.

Finally, after realizing other potential uses for the Leap, 2 more brackets were designed and printed so that the Leap can be securely installed onto the Oculus in a total of 3 different configurations.

The brackets can be viewed and downloaded here:

Bracket 1 Straight bracket used for visual IR passthrough from Leap camera

Bracket 2 Straight bracket used to minimize Oculus IR emitter occlusion

Bracket 3 Angles backet used to track hands with best angle – if no passthrough is desired
