Evaluating Physical/Virtual Occlusion Management Techniques for Horizontal Displays
نویسندگان
چکیده
We evaluate unguided and guided visual search performance for a set of techniques that mitigate occlusion between physical and virtual objects on a tabletop display. The techniques are derived from a general model of hybrid physical/virtual occlusion, and take increasingly drastic measures to make the user aware of, identify, and access hidden objects—but with increasingly space-consuming and disruptive impact on the display. Performance is different depending on the visual display, suggesting a tradeoff between management strength and visual space deformation.

Enveloping users and computers in a collaborative 3D augmented reality
We present EMMIE (Environment Management for Multiuser Information Environments), a prototype experimental user interface to a collaborative augmented environment. Users share a 3D virtual space and manipulate virtual objects that represent information to be discussed. We refer to EMMIE as a hybrid user interface because it combines a variety of different technologies and techniques, including ...
متن کاملOcclusion-capable multiview volumetric three-dimensional display.
Volumetric 3D displays are frequently purported to lack the ability to reconstruct scenes with viewer-position-dependent effects such as occlusion. To counter these claims, a swept-screen 198-view horizontal-parallax-only 3D display is reported here that is capable of viewer-position-dependent effects. A digital projector illuminates a rotating vertical diffuser with a series of multiperspectiv...
متن کاملReduced order modeling of head related impulse responses for virtual acoustic displays.
This study investigated the use of reduced order head related impulse response (HRIR) models to improve the computational efficiency in acoustic virtual displays. State space models of varying order were generated from zero-elevation HRIRs using a singular value decomposition technique. A source identification experiment was conducted under anechoic conditions in which three subjects were requi...
متن کاملVisuo-Haptic Illusions for Improving the Perceived Performance of Shape Displays
In this work, we utilize visuo-haptic illusions to improve the perceived performance of encountered-type haptic devices, specifically shape displays, in virtual reality. Shape displays are matrices of actuated pins that travel vertically to render physical shapes; however, they have limitations such as low resolution, small display size, and low pin speed. To address these limitations, we emplo...
