Paper Abstract

The purpose of this paper is to find the Target Locator Lines (TLLs) which perform best by contrasting and comparing experiment based on three kinds of TTLs of fighter HMD. 10 university students, male, with an average age of 21-23, corrected visual acuity 1.5, participated in the experiment. In the experiment, head movement data was obtained by TrackIR. The geometric relationship between the coordinates of the real world and coordinates of the visual display was obtained by calculating the distance from viewpoint to midpoint of both eyes and the head movement data. Virtual helmet system simulation experiment environment was created by drawing TLLs of fighter HMD in the flight simulator visual scene. In the experiment, eye tracker was used to record the time and saccade trajectory. The results were evaluated by the duration of the time and saccade trajectory. The results showed that the symbol“locator line with digital vector length indication” cost most time and had the longest length of the saccade trajectory. It is the most ineffective and most unacceptable way. “Locator line with extending head vector length symbol” cost less time and had less length of the saccade trajectory. It is effective and acceptable;“Locator line with reflected vector length symbol” cost the least time and had the least length of the saccade trajectory. It is the most effective and most acceptable way. “Locator line with reflected vector length symbol” performs best. The results will provide reference value for the research of TTLs in future.
