Two experiments were conducted at the Navy's Visual Technology Research Simulator (VTRS) to evaluate the influence of the Helmet Mounted Laser Projector (HMLP) on pilot performance. The HMLP is a proof-of-concept visual display systems for use in flight simulators which employs optics mounted on the pilot's helmet to project visual imagery onto a screen. The HMLP provides a wide-angle, low-resolution background display and a high-resolution inset or Area of Interest (AOI). The system is capable of using either head-tracking to reposition the entire display or combined head-and-eye tracking to reposition the AOI within the display as a function of eye movement. This provides an unlimited field of regard with high resolution at a lower cost than conventional systems. Both experiments reported here were conducted to assess how the HMLP affects pilot performance in the simulator on two different tasks. The results of the first experiment indicated that there were no operationally relevent differences between HMLP and fixed projection, nor were there any differences between head versus head-and-eye tracking on the air-to-ground weapons delivery task. The results of the second experiment indicated no significant differences between head tracking and head-and-eye tracking in the speed and accuracy of target identification. There were also no significant effects of altering the size of the blend region or length of delay in the eye-tracking mechanism.
