Variable Design Study in Human-Computer Interaction Experiment - A Case Study of Eye Tracking Technology

Research on color coding of fighter jet head-up display key information elements in air–sea flight environment based on eye-tracking technology

“…With a brightness range of [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] in the background, the color with a hue of 300 was selected for the key information. With a background with brightness range of [41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60], the color with a hue of 60 was selected for the key information. The background in this lightness interval does not have visual salience, and it is necessary to use a high-brightness color to produce a strong contrast.…”

“…44 Eye-tracking research in the field of domestic ergonomics is still in the exploratory stage. 45 Wetzel studied pilots' visual saccade path and visual attention features in three flight simulators. 46 The National Defense University of Taiwan studied military pilots in simulated flights on a simulator and found that the greater the workload, the larger the pupil diameter, and the greater the mental load, the smaller the average fixation time.…”

“…The color of HUD basic information characters is (150, 100, 100), and of key information characters is (300, 100, and 100). Figure 20(c) shows the recommended design scheme with a background of brightness range [41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60]. The color of HUD basic information characters is (150, 100, 100) and of key information characters is (60, 100, 100).…”

“…At the same time, the background color brightness interval that affects color matching was obtained, and five key information colors (K1(0, 100, 100), K2(30, 100, 100), K3(300, 100, 100), K4(330, 100, 100), and K5(60, 100, 100)) were selected for experimental exploration to obtain the best matching scheme for color coding of key elements of the HUD against different lightness backgrounds. The results indicate that against a flight background with ocean brightness, ranges are [1-20], [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40], [41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60], and [61-99] and colors with hues of 30, 300, 60, and 300 are selected for the key information. Finally, the results give an improvement and optimization plan for the HUD.…”
