Detailed Description


Short Description

The BBL-IS has 4 faces presenting seamless and perspective coherent 3D images. 

The acrylic coated screens from DaLite are the most visible part of the system. They present the images with a high contrast ratio and brightness transfer from the video projectors (brightness is up to 1600 cd/m² and resolution is 4 AM/OLP). The biggest screen is 2.8 m wide and 2.4 m height.

There are 4x Barco F70-4K8 able to project high resolution stereoscopic 3D images on each screen. These video projectors are driven using a single powerful graphic server (2x Intel Xeon Gold 6144 processors, 128 GB RAM, 2x nvidia Quadro RTX 6000 graphic cards with NVLink), making the BBL-IS a high-end but user-friendly VR CAVE system.

To react to user movements the BBL-IS uses a Vicon optical motion tracking system composed of 10x Bonita cameras. The system is able to perform full-body motion capture in real time for seamless interaction, and to record body motions to study the dynamic of movements according to the virtual situation.

A Denon AVR-1312 5.1 sound system is used to simulate accurate spatialized sounds in virtual environments.


A Multimodal System

The BBL-IS is in a complete synergy with all others BBL facilities, like the fMRI and the EEG facilities. 
Moreover, it can be coupled with multiple devices to extent the stimulation and recording capabilities.

Advanced Stimulation

  • Olfactomer capable to deliver 28 different odors, adressing each nostrils separatly and with a very low latency (half a second).
  • FACSGen accurate facial expressions controlled by action units.
  • HRTF sounds for accurate and personalized sound spatialization.
  • Haptic stimulation all over the body using Metawear MotionR sensors.
