Near-Field VR Wins Immersive Realities Contest at SIGGRAPH 2015



The MxR Lab has been hard at work creating a unique immersive experience entitled “Discovering Near-Field VR: Stop Motion with a Touch of Light-Fields and a Dash of Redirection,” which just won the Immersive Realities AR/VR Contest at SIGGRAPH 2015. The contest was held to showcase the best immersive reality applications with live demonstrations in the new VR Village venue.

“Discovering Near-Field VR” combined efforts across disciplines at USC with students from the School of Cinematic Arts and the Viterbi School of Engineering collaborating with researchers at the Institute for Creative Technologies to produce a unique piece that introduces the art of stop motion animation to the field of virtual reality. The goal was to create a surreal experience by developing virtual reality techniques that look unlike traditional game engine graphics and leverage the perceptual affordances of the near-field. Light field rendering and redirected walking techniques were leveraged to create an interactive full-body experience.

The Immersive Realities AR/VR contest had 48 submissions from all over the world. A total of ten pieces were demonstrated at the VR Village, with the contest winner selected between the top three finalists.

This effort brought together the contributions of numerous people across multiple disciplines. We would like to express our sincere gratitude to everyone that made “Discovering Near-Field VR” possible:

DARPA to release software developed by Mixed Reality Lab

The Defense Advanced Research Projects Agency (DARPA), is responsible for funding and developing blue sky advancements in technology and science for the US Department of Defense. These have included significant roles in developing GPS, the Internet, autonomous cars, integrated circuits, and hypersonic aircraft. DARPA has now made some of their software available for free through an Open Source Software Catalog:

ICT’s Mixed Reality Lab is proud to be represented in this catalog with software related to “Immersive Body Based Interactions”, a research project that seeks to understand and address the human computer interface challenges raised by Big Data. MxR team members David Krum and Thai Phan developed and contributed software for low cost tablet based virtual reality displays and innovative multi-touch software for accessing large databases.

Virtual Human Display Study

We are offering $20 to participate in a research study to investigate how virtual reality displays can affect how people react to virtual human characters. Virtual human characters are characters that are computer generated and controlled. This study may help us to understand how to choose equipment and design virtual characters for virtual reality training systems.

If you volunteer to participate in this study, you will be asked to use a helmet mounted display weighing 1 lb (see picture) and observe a virtual human character. We will also ask you to fill out questionnaires before, during, and after your observations. We anticipate that your total participation will last 30 minutes or less.

To be eligible to participate, you must be over the age of 18, able to stand without assistance, able to communicate comfortably in spoken and written English, and have 20/20 vision or vision corrected using glasses or contact lenses.

All participants will receive the compensation at the end of their participation. The study will take place at the USC Institute for Creative Technologies. Please note that this is not located on the USC campus.

Location: 5318 McConnell Avenue, Los Angeles, California 90066. (Off of W. Jefferson Blvd, between Lincoln and S. Centinela).

Participation in this study is completely voluntary, and the decision whether or not to participate will not in any way affect student or employment status at the University of Southern California.

If you are interested in participating, please schedule an appointment online by clicking the following link:

To learn more about the study, please email David Krum. You may also telephone on business days between the hours of 9 AM – 4 PM PST.
