|Virtual Reality PowerWall||The Virtual Environment is projected on a 4x2 m screen by two Christie Mirage S+ 4000 projectors, synchronised with StereoGraphics CrystalEyes active shutter glasses. We use a Sun 333.3 workstation (dual core AMD Opteron, processors 2218, 2.60 GHz, 2.50 GB RAM) with Windows XP Professional and Nvidia Quadro FX 4600 video card.|
|3D desktop||A 19” 3D monitor is plugged to a machine with an NVidia FX4800 quad buffer graphic card, for the 3D visualization. Four Optitrack cameras are placed around the desk for tracking the passive markers during the interactions.|
|Phantom||Phanthom Omni R
by Sensable Technologies. The device has six DOF positional sensing and 3 DOF force actuation in a workspace of
160 W x 120 H x 70 D mm. The maximum exertable force at nominal (orthogonal
arms) position is 3.3 Newton.
|Intersense Tracking System||The head of the user is tracked in position and orientation by an Intersense IS900 inertial-ultrasonic motion tracking system. A tracked wanda is used for interaction with the VE.|
|Optitrack Tracking System||An Optitrack FLEX:100 system composed of 12 infrared cameras is used for tracking passive markers.|
|Nexus 4||Device for physiological monitoring by MindMedia . The device is a portable system that supports up to four channels,
with different signals at 24 bits and 1024 samples per second (EMG, ECG, EEG) or 128 samples per second (GRS, Respiration, Skin Temperature and others).
|Portable 3D stereoscopic system||The PC used for the desktop 3D is connected to a portable DELL 3D projector. The VE is visualized on a portable retro-projected 240x180cm screen.|
|3D Audio||14.1 audio system, composed by a m-audio profire 2626 audio interface, routing 15 outputs to two 8 channel power amplifiers. The 15 audio out streams are sent to the amplifiers through the 2 optical digital outputs of the audio interface. Each optical output is demultiplexed and converted into parallel analog signals, which feed the analog XLR inputs of the two amplifiers.|
