Embedded Virtual Driver Training Technologies

The objective of topic A07-192 of Army SBIR 07.2 is to develop and demonstrate a prototype visual imaging solution for low-cost, virtual, fully embedded vehicle driver training focused on current force combat vehicle vision blocks and night driving sources. Optical Resolutions Incorporated (ORI) and its subcontractor, RTI International, propose to select and design a visual system concept chosen from trade offs conducted between possible visualization system solutions and the physical constraints of current force combat systems driver stations. These solutions will be based on extensions to the vehicle vision blocks and will incorporate the ability to display the output of night vision sensors. We will research newly available optical and display components; view-mode switching techniques; micro-fabrication methodologies; and interface technologies to transform the conventional, direct view vision block into a dual-purpose viewing device that supports, in addition, a driver visualization of a virtual battlefield. In phase I, the project team will study the configuration of driver crew stations of current force fighting vehicles (Abrams, Bradley, Stryker, etc.) to determine which one is most amenable to the implementation of a switchable vision block (SVB). This determination will be based on tradeoffs between possible solutions to provide ET to the driver station. The interface between the SVB and the image generator will be implemented to connect, in the indirect view mode, to either the VR training data base or the video products of the night vision technology device(s) to support day and night combat operations without the need for a separate, dedicated night vision port. We will also investigate HUD-like projection technologies capable of supporting yet a blended view mode in which sensor-derived information can be overlayed over the real world scene for enhanced situational awareness. This phase of the project will culminate with the selection of a combat system and a corresponding SVB concept design for driver ET. Available and developing technologies in optics, displays, and wireless transmission will also be researched to attain the most reliable, lowest cost and weight possible implementation of an SVB to satisfy the ET, virtual driver training requirements.
