Embedded Virtual Driver Training Technologies

The objective of topic A07-192 of Army SBIR 07.2 is to develop and demonstrate a prototype collimated visual imaging solution for low-cost, virtual, fully embedded vehicle driver training focused on current force combat vehicle vision blocks and night driving sources. This multi-purpose visualization solution is referred to as a switchable vision block (SVB). In phase I, driver crew stations of the Abrams, Bradley, and Stryker were considered to determine which one was most amenable to the implementation of a SVB. Based on space availability and possible occlusion of displays, we selected the M17 vision blocks in the Stryker driver compartment as the host for the SVB. We also researched newly available optical and display components; view-mode switching techniques; micro-fabrication methodologies; and interface technologies to develop concepts for the SVB. During Phase I we constructed an EO switch mirror based on a prior ORI concept. We developed six SVB configurations from which we down-selected to one on the basis of minimum number of optical elements and simplicity of the view mode switch. The recommended SVB concept consists of an optical subsystem with three optical elements; a switch mirror; a display subsystem and an SVB to vehicle interface subsystem housed in an additional physical module below the basic vision block; and the SVB housing subsystem. In phase II of this project, we will design, develop, characterize and demonstrate a prototype of the recommended SVB. This will be done in two stages. In stage 1, we will implement an SVB for stand alone demonstration in December, 2008. In stage 2, an engineering prototype will be implemented for demonstration and evaluation in a Stryker driver compartment environment in December, 2009. During stage 2, we will also continue to track developments in optical elements, displays (OLEDs), and wireless transmission (video and power) and report the findings in the Phase final report which will also include a technical data package and an updated commercialization plan for the SVB.
