AR 3D Hologram Coffee Table
Impressive (yet limited) table gives impression of 3D holographic graphics with true depth and multitouch interface. In reality, it is a projection underneath using head-tracking via a Microsoft Kinect:
Table details:
Width: 80 cm
Lenght: 100 cm
Height: 55 cm
Display Size: 80cm x 60cm
Beamer : BenQ MS612ST Wideangle beamer
Camera : PS3 Eye with Wide Angle Lens 1.8mm 111° Field of View (FOV)
Infrared lighting: 4 infrared laser one in each cornerHeadtracking:
As few of you have mentioned at the moment it only works for one person, with more persons in the room, only one person has the correct view.
How i works is pretty simple, with the kinect I detect the headpositions of the user and map it to the coordinate-system of the table.The technique for calculating the right perspective is called off-axis projection or Fishtank VR.
I don’t want to go in to much detail because there are so many papers out there which can give you really good explanation.
If you are interested google for these topics. To get a quick start look at the code of Johnny Lee’s VR Desktop code—>
