Dynamic projection environments for immersive visualization

Abstract

Figure 1. Our immersive and dynamic projection environment enables users to control visualization by manipulating the position and orientation of the projection surfaces. We present a variety of interactive demonstration applications leveraging our new interface. AbstractWe present a system for dynamic projection on large, human-scale, moving projection screens and demonstrate this system for immersive visualization applications in several fields. We have designed and implemented efficient, low-cost methods for robust tracking of projection surfaces, and a method to provide high frame rate output for computationally-intensive, low frame rate applications. We present a distributed rendering environment which allows many projectors to work together to illuminate the projection surfaces. This physically immersive visualization environment promotes innovation and creativity in design and analysis applications and facilitates exploration of alternative visualization styles and modes. The system provides for multiple participants to interact in a shared environment in a natural manner. Our new human-scale user interface is intuitive and novice users require essentially no instruction to operate the visualization.

Physical Avatars in a Projector-Camera Tangible User Interface Enhance Quantitative Simulation Analysis and Engagement

“…This work was extended in Shader Lamps [16]. Similarly to Raskar et al [16], Sheng et al [17,18], and Yapo et al [21], our system projects information on neutrally colored physical primitives to create a detailed rendering of a simulated space. Our physical primitives and rendering options provide unique extensions to their work.…”

High-speed transition patterns for video projection, 3D reconstruction, and copyright protection

“…1 It is also possible to use a time-of-flight (TOF) camera to obtain 3D information for augmented reality applications [11] (more information on TOF cameras can be found in [7]). Infrared LEDs or retro-reflectors can also be installed in the scene and tracked in 3D using the relative position of the LEDs with respect to an infrared camera [25]. A somewhat related application designed to compensate for vibration in industrial 3D scanning is presented in [15].…”

Visualisation Techniques for Using Spatial Augmented Reality in the Design Process of a Car

“…This approach was used in applications where the geometry of the scene is unknown [NPGN03, GPNB04, BEK05]. A distributed rendering system, which is able to compute the projection images for multiple projectors and moving projection surfaces, was presented in [YSN*10]…”
