Plan for Evaluation of the Training Potential of Helmet-Mounted Display and Computer-Generated Synthetic Imagery

摘要

This report describes a plan of empirical research to evaluate the training effectiveness of a helmet-mounted display (HMD), and of computer-generated synthetic imagery (CGSI), for low level flight, navigation, and target interaction. This HMD has been developed by the Advanced Simulation Concepts Laboratory of the Naval Training Equipment Center for use in the Navy Visual Technology research Simulator (VTRS). Optics mounted on the pilots's helmet project a scene upon a retro-reflecting screen. Two computer-image generation (CIG) channels are incorporated which present a wide-angle, low-resolution, low-detail background and an area of interest (AOI) of high resolution and detail. Eye and head tracking are used to position the display so that the AOI is presented to the fovea. The goal of HMD is to present a scene to the pilot that is indistinguishable from the real world insofar as pilot performance is concerned. The evaluation plan describes training scenarios emphasizing low level flight and ground interaction, response parameters used in measuring pilot performance, psychological experiments comparing the training efficacy of various aspects of HMD and CGSI, post stimulation subjective measures pf pilot comfort, and the logistics of the research plan itself.
