Augmented Reality SandBox is quite nice concept where you play with sand and a projector mounted on top of the sandbox projects constantly updating height-map on it. We've prepared a few installations.

Basic Instructions

Log in, start the app (icon in top left corner), right click - view - load view, select /home/brmlab/Desktop/CustomView0001.view or something, right-click on the window bar and select fullscreen. Voilá.



Software created by Oliver Kreylos for W.M. Keck Center for Active Visualization in the Earth Sciences, UC Davis Tahoe Environmental Research Center, Lawrence Hall of Science, and ECHO Lake Aquarium and Science Center. See for more info.


It may be quite hard to find out how to calibrate for the first time, so i will document it here a bit

Kinect (Height calibration)

Tou have to manually edit files in PISKOVISTE/SARndbox-1.5-001/etc/SARndbox-1.5/ :


(-0.0076185, 0.0271708, 0.999602), -115.0000
(  -48.6846899089,   -36.4482382583,   -111.8705084084)
(   48.3653058763,   -34.3990483954,   -106.3884158982)
(   -50.674914634,    35.8072086558,   -114.4082571497)
(   48.7936140481,    36.4780970044,     -108.74159795)

The important is the last number in each line - in the first line is z-offset of sea level, the four lines are corner calibration points (must be always higher value than the sea level offset). To move sea level up, increase the value on all lines by the same amount.

Mapping from height to colors. Adjust the appropriate z-offsets (first column) to compress/spread colors across heights.

IAMap SandBox


CUstom reimplementation of AR Sandbox that is capable of running on less-advanced hardware than SARndbox (which requires quite decent graphics card), designed with ARM platform in mind (like Raspberry Pi or BeagleBoard).


FreezeFest 2012

This installation was created for DIY festival FreezeFest 2012. It used ad-hoc on-site construction, around 60kg of sand and SARndbox software (see below).


JDI 2012

This installation was created for One Day with Informatics event held at Charles University Prague. It used IKEA1 construction, 50 kg of sand and SARndbox software (see below).




This portable construction was used for JDI 2012 installation (see photos above) and will be stationed at brmlab. It uses the following components from IKEA (hence the name):


This portable construction is built from IKEA components and custom parts from OBI.
