Black Marble Interactive LED Floor

Automatic Calibration

The control system for the Black Marble interactive LED floor constantly calibrates the floor surface to make sure it only reports back actual touches and neglects transients, such as dirt, chairs or other foreign objects.

100 Sensors per Panel

In order to make the LED panels fully interactive the 100 optical sensors per panel are all IR sensors, they are unaffected by any ambient light or other IR cameras etc., even by direct sunlight.
The key feature of having 100 sensors per panel is that thousands of sensors can be active at any point in time and the density of the sensors provides very detailed sensing information within 2.3 inches or 6cm. The TouchController can support 100,000+ active sensors every 33 milliseconds, so for very large events or productions where there are hundreds of people on the stage, every sensor is tracked perfectly and you can be sure the visuals are always perfectly positioned and perfectly synchronized. If you think about every sensor having an XY coordinate on a stage, it’s easy to visualize how the sensors interact with the content.

System Requirements

To make your system work you need these components:

• ROE Black Marble Interactive Panels
• BrightLogic TouchController TCX4
• BrightLogic Video Controller VC6
• Media Server such as Disguise, Green Hippo, BrightLogic etc.

The TouchController provides touch data in multiple formats, enabling designers and developers to create real-time generative graphics based on the touch data. Keep in mind the Black Marble panels can also be vertically mounted for interactive wall installations.

Content Creation Tools

Content creation tools come in two categories, tools for designers or developers. Designers can use the tools they know, such as Notch and TouchDesigner which both offer a visual yet powerful workflow for creating dynamic content (in fact, Notch and TouchDesigner can be used together as well). For developers looking to program their content using tools such as OpenFrameworks, Cinder, Unity, connector libraries are available for the TouchController and developers can either use the XML API or the NDI Feed from the TouchController.
