Welcome!

What Is an AR Sandbox? (and how to build one)

An Augmented Reality Sandbox Is:

• a box filled with white sand
• a projector mounted over the sand
• a Kinect depth-sensing camera mounted over the sand
• a computer that runs software projecting images on the

sand # # # # # # Augmented Reality: Computer-generated media (images, sounds) projected on a real-world scene, which change in response to interaction from players in the real world.

How It Works

Let’s Watch!

Part A: Hardware

Kinect depth-sensing camera + short-throw digital projector + a computer

This video explains how Kinect works:

Part B: Software

We are using the Magic Sand software by Thom Wolf and Rasmus Paulsen. This software is Windows-based. How to build a Magic Sandbox: https://imgur.com/gallery/Q86wR

Part C: Assembly

• Put your sandbox where you want it. (On a table, on the floor, in a frame)
• Set up the vertical support device for the Kinect camera and the projector.

(Tripod or wood pillar) (If using a tripod, extend it approximately 80 inches above the floor.)

• Set up the horizontal support (mounting board / shelf) that holds the

Kinect and projector. (If the sandbox is 24 inches wide, then the camera and projector should be (2 x 24 = 48) inches above the sand.) Rule of thumb: Projector height is twice sandbox width.

• Fill sandbox with sand (minimum 50 lbs, preferably 80 to 100 lbs)
• Plug in cables. (Wiring diagram follows)
• Run software calibration
• Run Magic Sand software
