The Visions Project K. is a volumetric device that allows
pseudo visualization of 3-D objects and their interaction
with the user.

Visions Project K.
AIMS:
VISIONS Poject K. 1.0 (Interactive video hologram ), is research project on the
video holograms and interactive 3D devices, which was presented at the Medialab- Prado
Center for Digital Art Culture in Madrid in February 2012.
TO RESEARCH ON 3-D DISPLAY DEVICE AND DEVELOP A LOW COST
PROTOTYPE, EASY TO ASSEMBLE, THAT USE A OPEN SOURCE
SOFTWARE;
TO VISUALIZE 3-D IMAGE AS VIDEOHOLOGRAMS;
TO EXPERIMENT USER INTERACTION as EXPERIENCE WITH
3-D IMAGE FLOATING IN THE AIR: HAPTIC INTERACTION AND VISUAL
INTERACTION.
Firstprototype: Medialab-Prado 2009
Objects are projected onto a pyramidal structure with a LCD monitor, and due
to the special geometry of the structure, it looks like real 3-D objects floating
inside the pyramid for any observer from any direction.

How visualize 3-D images
Visions Project K.
Optical System
Visions Project K.
There are 2 types of interaction user: visual and haptica
The device use a Kinect camera to
capture the interaction;
a LCD monitor to projecting the 3-D
image;
a PC to process and control the
device;
a pyramidal structure where the
image is projected;
a external structure to support the
monitor and protect the pyramid;
How does it work?
DIYa digital fabrication
Visions Project K.
• This project has been
conceived like a low cost DIY
portable device;
• The structure is light and easy
of build and dismantle;
• all the information necessary
to create, build and how to make that work isshare by a Creative Commons License

OPEN DESIGN: Sketchup
The materials to build the
entire device are:
8 plastic tubes (45 cm).
4 plastic tubes (20 cm).
4 plastic triangles to build the
pyramid
4 corners to support the
pyramid and the structure.
4 corners to support the
monitor.

HACKING KINECT by
Software: Processing in multiplatform
• The device use a Kinect camera, in order to visualize people in 3-D
space; It use an open source drivers
• The OpenNI framework provides a set of open source APIs. These APIs are intended to become a standard for applications to access natural interaction devices.
• The APIs provide support for Voice and voice command recognition; Hand gestures; Body; Motion Tracking
• The software was developed with the OpenNI library for
Processing;
