Paper Abstract

A methodology for developing helmet-mounted display (HMD) symbology from conception to flight is being developed within the Defence Evaluation and Research Agency (DERA). As part of this development, experiments have been undertaken to evaluate target locator cues (TLCs). A TLC is designed to represent the direction and angular distance from the pilot's line-of-sight outside the HMD FOV. A previous study by Geiselman and Tsou identified three potentially effective TLCs which were used in these experiments. The first experiment was conducted on the DERA fused imagery simulation testbed (FIST). FIST is a simulation facility which projects images on a large curved screen to simulate HMD and HUD symbology. A 10 degree simulated FOV was used for the HMD symbology. The results showed two of the TLCs to be significantly better than the third. The experiment was repeated using the Viper II helmet used. The result were very similar to those obtained in the first experiment, helping to validate the use of low fidelity simulation in symbology development.
