To investigate the effects of haptic feedback on the task-sharing performance during approach when using a Tunnel-in- the-Sky display, a within-subject simulated experiment with 12 participants was conducted in the SIMONA Research Simulator at Delft University of Technology. The experiment consisted of a primary Tunnel-in-the-Sky tracking task, where the pilots had to fly with one non-haptic and two haptic settings. Primary task performance was measured by means of position errors and roll and pitch rates. A secondary task was presented to the pilots as bucket shaped figures superimposed on the outside visuals, where the participants had to indicate the direction of the divergent figure. Secondary task performance was measured by success rate, average time to answer correctly and - by means of eye-tracker measurements - head-up time and number of gaze switches. Next to these objective measures pilots provided a subjective measure of their mental effort after each run. Lastly, the haptic and human induced forces were recorded, to be able to measure whether the pilot was fighting or cooperating with the haptic feedback provided. Results of the experiment show that haptic feedback can significantly increase task-sharing performance of the pilot, especially for a challenging primary task, but that too dominant haptic feedback can introduce a risk of over-reliance.
