People-tracking orb demo makes us want to build our own - Hack a Day

People-tracking orb demo makes us want to build our own

Earlier this week, we came across a video of an orb-based eyeball that would follow you throughout the room, based on data gathered from a Kinect sensor. Try as we might, we couldn’t find much more than the video, but it seems that the guys behind the project have spoken up in a recent blog post.

[Jon George] of The Design Studio UK explained that the person-tracking eyeball visualization was built using a PC, a Kinect, and a product called the Puffersphere, which projects a 360 degree image on the inside of a glass orb. A panoramic image is converted for use by the special lens inside the sphere by applying a filter which warps the image into a circular shape.

After the image has been created, a simple Windows app is used in conjunction with the OpenNI framework that allows the image to follow you around the room.

The only problem with this fun little project is the price of the sphere – we’re not sure what it is exactly, but rest assured it is more than we are willing to pay for such a toy. We’re thinking there has to be a way to simulate the orb’s effect to some degree using cheaper hardware. It’s possible that it could be done using a small-scale DIY version of this spherical mirror projection build, though it consists of concave half-spheres rather than full orbs.

In the meantime, take a look at these two videos of the orb in action. Don’t worry – we know you were totally thinking about the Eye of Sauron, so the second video should not disappoint.
