Section 2: CAVE Overview 2.3 System Control The display system is controlled by a 10” touch panel, which allows users to control audio/visual components in the CAVE. For information on all third-party supplied equipment, refer to the COTS manuals. For more information on the control interface, refer to Section 3 Control Panel Interface. FIGURE 2-3 TOUCH PANEL CONTROL FOR CAVE DEVICES 2-4 NASA Goddard Flight Dynamics CAVE User’s Manual 020-100049-01 Rev.
Section 2: CAVE Overview 2.4 CAVE Components 2.4.1 Projectors The display system uses four Mirage S+4K projectors (38-DSP104-06), a 4000 lumens, three chip DLP™ projector, delivering native SXGA+ resolution with a 1.25:1 fixed lens. For more information, refer to the standard Christie Mirage S+/HD, DS, DW, DLV User’s Manual (#020-100001-xx).
Section 2: CAVE Overview 2.4.3 5.1 Audio System The amplifier can run in 5.1 native mode for audio connected from host 16 or in pseudo surround sound for laptop stereo sources. Audio amplifiers and distribution equipment are housed in the AV equipment rack. For more information on the rack, refer to 2.4.8 AV Equipment Rack, on page 2-8.
Section 2: CAVE Overview 2.4.5 Control Center The control center provides a single control position for the CAVE equipment. It consists of an AV equipment rack, a CRT monitor, a laptop connection, a wired keyboard and mouse, an A/B keyboard/mouse switch and stereo 3D equipment (i.e., wired stereo glasses). An NTI xtender is used to extend the keyboard/mouse from the customer supplied IG to the control center.
Section 2: CAVE Overview 2.4.8 AV Equipment Rack The AV rack houses the equipment provided by Christie Digital System Inc. The rack includes an 8x8 highbandwidth video matrix switch, which supports 8 inputs and 8 output channels. The 8x8 matrix routes the 4 video channels from the customer supplied IG to the four projectors and control monitor. Currently, 6 inputs and five outputs are populated; therefore, there are 6 possible sources available to 5 destinations.
Section 2: CAVE Overview 2.4.9 Tracking System A 6° of freedom wireless motion tracking system is installed to support computer applications that use a head and wand motion tracking. The tracking system uses hybrid technology with gyroscopically corrected inertial sensors and an ultra-sonic reference grid. For more information, refer to Section 4 Tracking System and the InterSense IS900 User’s Manual. FIGURE 2-11 INTERSENSE TRACKING SYSTEM 2.4.
