==miniSim™ Driving Simulator Description==
 +
General Architecture  <br>The driving simulator described in this document represents an advanced, flexible, and reliable driving simulator for the research needs of any high level research facility.  The technology contained in the simulator represents over 25 years of simulator software development by the professional staff at the University of Iowa Driving Safety Research Institute (DSRI), home of the National Advanced Driving Simulator (NADS), and leverages the software and experience behind the world-renown NADS-1 and NADS-2 simulators and the more recently developed miniSim™ PC-based simulator.
 +

==miniSim™ Software and PC==
 +
The software delivered with all miniSim simulators consists of the following tools:
 +
* The <b>Tile Mosaic Tool</b> (TMT) for assembling a road network from a library of over 450 road and landscape segments called ‘Tiles’.  You use the TMT to connect them together and export a complete road network to the ISAT and miniSim. DSRI can also create new tiles or modify existing ones to meet your specific needs.
 +
* The <b>Interactive Scenario Authoring Tool</b> (ISAT) for building scenarios on the assembled database. The ISAT is windows-based and does not require scripting.
 +
* The <b>miniSim</b> runs the scenario on the assembled database and provides both real-time measures and a comprehensive data acquisition file for post-processing in Matlab.
 +
* The <b>nDaqTools</b> are DSRI-design interfaces for Matlab to define the measures to be calculated, and to organize and control the data reduction process.
 +
<br>
 +
The typical miniSim™ PC hardware specification is as follows:
 +
* Rackmount PC case
 +
* Windows 10 Pro 64-bit OEM
 +
* Intel Core i9 3.7GHz 10-Core Processor
 +
* 2 SSD in RAID (1 Tb ea, 1 Tb usable)

* Three general  options are available:  
* Two front projectors of 1080p (1920 x 1080) resolution
+
** Cylindrical soft screen of about 10 ft radius, with 1920 x 1080 projectors
* One 116” rear projection screen with projector of 1080p (1920 x 1080) resolution
+
** Three flat projection displays with 9ft radius, with 1920 x 1080 projectors
* The miniSim PC will perform the warping/blending using Scalable Desktop from Scalable Display Technologies.
+
** Large LCD displays (75, 85 and 100 inch)
 
+
* One 116” rear projection screen with 1920 x 1080 projector
The miniSim PC contains NVIDIA Quadro Maxwell M6000 and M4000 cards to support the automated warping and blending application and projector synchronization.  The system provides manual and automated alignment and blending between the two front channel projectors, with the included GigE Camera.  The alignment camera can be mounted to the roof of the cab, or on a tripod placed at the driver eyepoint.

<br>
For the proposed two-projector system with warping and blending, two NVIDIA Quadro cards are required; The M6000 for the front two projectors, and the M4000 for the rear channel and operator display. For this system, three projectors of 1920 x 1080 pixel resolution are proposed. The projector will be DLP with a contrast ratio of at least 10,000 and brightness greater than 2000 lumens, such as the BenQ 1085ST.  This unit accommodates a short throw (throw ratio 0.67-0.83), allowing the placement of the projectors over the cab and safely out of the way. NADS will supply the projector mounts and mounting location information; the customer will install the mounts per NADS specifications.

+
Cost of the half cab miniSim™ varies widely depending on the host vehicle used and the particular configuration desired. Historically average costs have been $250k-$500k including onsite installation and training. Please call for exact quote.  
Due to the room requirements, video and USB extenders are used between the minisim PC and the operator station so that they can be separated by up to 50 ft.  A 4-channel high-definition video monitoring system is included that provides a high-quality quad-split display to monitor the simulator and research participant.  As an option, a NADS VidCap video recording PC can be included that will record this quad-split channel, with user-selectable data (including frame number) superimposed on the video to allow later analysis and comparison with the recorded simulator data.

The start date for the project occurs when NADS receives the Award Activation Notice (AAN) issued by the University’s Division of Sponsored Programs (DSP).  This occurs after DSP has reviewed the Purchase Order and any issues have been resolved.
