KEYNOTE: Immersive 3D Display Systems

Abstract: Paul will share some of his more than 25 years of experience in the development of immersive 3D display systems. He will discuss the challenges, issues and successes in creating, displaying and experiencing 3D content for audiences. Topics will range from working in dome and curved screen projection systems to 3D in use at Los Alamos National Labs to working with Ang Lee on “Billy Lynn’s Long Half Time Walk“ and “Gemini Man” at 4K, 120Hz per eye 3D as well as his work with Doug Trumbull on the 3D Magi format. Paul will explore the very important relationship between the perception of 3D in resolution, frame rate, viewing distance, field of view, motion blur, shutter angles, color, contrast and “HDR” and image brightness and how all those things combined add to the complexity of making 3D work effectively. In addition, he will discuss his expertise with active and polarized 3D systems and “color-comb” 6P 3D projection systems. He will also explain the additional value of expanded color volume and the inter-relationship with HDR on the reproduction of accurate color.

KEYNOTE: Multiple Viewer Stereoscopic Displays

Abstract: Many 3D experiences, such as movies, are designed for a single viewer perspective. Unfortunately this means that all viewers must share that one perspective view. Any viewer positioned away from the design eye point will see a skewed perspective and less comfortable stereoscopic viewing experience. For the many situations where multiple perspectives would be desired, we ideally want perspective viewpoints unique to each viewer’s position and head orientation. Today there are several possible Multiviewer solutions available including personal Head Mounted Displays (HMDs), multiple overlapped projection displays, and high frame rate projection. Each type of solution and application unfortunately has its own pros and cons such that there is no one ideal solution. This presentation will discuss the need for multiviewer solutions as a key challenge for stereoscopic displays and multiple participant applications, it will review some historical approaches, the challenges of technologies used and their implementation, and finally some current solutions readily available. As we all live and work in a collaborative world it is only natural our Virtual Reality and data visualization experiences should account for multiple viewers. For collocated participants there are several available solutions now that have built on years of previous development, some of these solutions can also accommodate remote participants. The intent of this presentation is an enlightened look at multiple viewer stereoscopic display solutions.

Abstract: Medical imaging is used extensively world-wide to visualize the internal anatomy of the human body. Since medical imaging data is traditionally displayed on separate 2D screens, it needs an intermediary or well trained clinician to translate the location of structures in the medical imaging data to the actual location in the patient’s body. Mixed reality can solve this issue by allowing to visualize the internal anatomy in the most intuitive manner possible, by directly projecting it onto the actual organs inside the patient. At the Incubator for Medical Mixed and Extended Reality (IMMERS) in Stanford, we are connecting clinicians and engineers to develop techniques that allow to visualize medical imaging data directly overlaid on the relevant anatomy inside the patient, making navigation and guidance for the clinician both simpler and safer. In this presentation I will talk about different projects we are pursuing at IMMERS and go into detail about a project on mixed reality neuronavigation for non-invasive brain stimulation treatment of depression. Transcranial Magnetic Stimulation is a non-invasive brain stimulation technique that is used increasingly for treating depression and a variety of neuropsychiatric diseases. To be effective the clinician needs to accurately stimulate specific brain networks, requiring accurate stimulator positioning. In Stanford we have developed a method that allows the clinician to “look inside” the brain to see functional brain areas using a mixed reality device and I will show how we are currently using this method to perform mixed reality-guided brain stimulation experiments.

Christoph Leuze is a research scientist in the Incubator for Medical Mixed and Extended Reality at Stanford University where he focuses on techniques for visualization of MRI data using virtual and augmented reality devices. He published BrainVR, a virtual reality tour through his brain and is closely working with clinicians on techniques to visualize and register medical imaging data to the real world using optical see-through augmented reality devices such as the Microsoft Hololens and the Magic Leap One. Prior to joining Stanford, he worked on high-resolution brain MRI measurements at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, for which he was awarded the Otto Hahn medal by the Max Planck Society for outstanding young researchers.

Abstract: With all the hype and excitement surrounding Virtual and Augmented Reality, many people forget that while powerful technology can change the way we work, the human factor seems to have been left out of the equation for many modern-day solutions. For example, most modern Virtual Reality HMDs completely isolate the user from their external environment, causing a wide variety of problems. "See-Through" technology is still in its infancy. In this submission we argue that the importance of the social factor outweighs the headlong rush towards better and more realistic graphics, particularly in the design, planning and related engineering disciplines. Large-scale design projects are never the work of a single person, but modern Virtual and Augmented Reality systems forcibly channel users into single-user simulations, with only very complex multi-user solutions slowly becoming available. In our presentation, we will present three different Holographic solutions to the problems of user isolation in Virtual Reality, and discuss the benefits and downsides of each new approach.
