CURRENT STUDIES
A cylindrical volumetric display has been
implemented and tested to project and track
a medical dataset of a virtual skeleton.
A table-top display is also been tested to
project an architectural model of the Beaumont
Tower, a landmark icon of the MSU Campus.
Several other displays are being conceptualize
to research other volumetric datasets. This
includes potential design displays such as
Pyramid, and Sphere.
Design of a User study to investigate the
factor affecting the display and perception
of volumetric datasets in the projective AR
displays.

Projective Augmented Reality Volumetric
Displays
PROJECT GOALS
• To devise and implement displays that can accommodate spatially
matched volumetric datasets transmitted between two or more
remotes sites connected thru an Internet2
connection and are being projected onto an Augmented
Reality environment by a Projective Head Mounted Display.
• To research what types of volumetric displays provide the
greatest visual properties for AR objects and physical
presence of interacting collaborators for different types
of 3D volumetric datasets.
DESCRIPTION
The Projective Augmented Reality Volumetric Displays are
an important component of the Teleportal Project. The displays
main function is to embed in the environment computer generated
objects, creating an augmented environment that would allow
the participants of the system to be enclosed in a stereo,
immersive environment capable of holding spatially distributed
volumetric datasets such as medical, engineering, and scientific
data being shared across sites.
The displays are clothed with a special optical 3M retro-reflective
material. The material is flexible enough to be clothed
around most
surfaces, thus creating a great potential for designing
or transforming any existing objects or displays into a projective
AR display.
The retro-reflective material optical properties allow it
to reflect back to its source with very little diffusion whatever
computer-generated image is being projected onto it.
In our case, the light-emitting source is a stereoscopic
Projective
Head Mounted Display, so the material can reflect
back to the eyes of the user the stereoscopic image, thus
allowing stereoscopic perception.
