Where Virtual Meets Real: Perceptually-Driven Inputs for New Output Devices

Abstract:

There has been a tremendous increase in quality and number of new output devices, such as stereo and automultiscopic screens, portable and wearable displays, and 3D printers. Some of them have already entered the mass production and gained a lot of users' attention; others will follow this trend promptly. Unfortunately, abilities of these emerging technologies outperform capabilities of methods and tools for creating content. Also, the current level of understanding of how these new technologies influence user experience is insufficient to fully exploit their advantages. In this talk, I will demonstrate that careful combinations of new hardware, computation, and models of human perception can lead to solutions that provide a significant increase in perceived quality. More precisely, I will show how careful rendering of frames can improve spatial resolution beyond physical capabilities of display devices. Next, I will discuss techniques for overcom ing limitations of current 3D displays. In the context of 3D printing, I will present methods for specifying objects for multi-material 3D printing.

Biography:

Piotr Didyk is an Independent Research Group Leader at the Cluster of Excellence on "Multimodal Computing and Interaction" at the Saarland University (Germany), where he is leading a group on Perception, Display, and Fabrication. He is also appointed as a Senior Researcher at the Max Planck Institute for Informatics. Prior to this, he spent two years as a postdoctoral associate at Massachusetts Institute of Technology (MIT). In 2012, he obtained his Ph.D. from the Max Planck Institute for Informatics and the Saarland University for his work on perceptual display. During his studies, he was also a visiting student at MIT. His research interests include human perception, new display technologies, image and video processing, and computational fabrication. He focuses on techniques that account for properties of the human sensory system and human interaction to improve perceived quality of the final images, videos, and 3D prints.
