In this paper we investigate the efficiency of five different image-space post-processing gaze guidance techniques adapted for immersive environments, probing our peripheral vision’s sensitivity to different stimuli embedded in complex, real-world panorama still images. We conducted an extensive perceptual study for the commercially available HTC Vive Head-Mounted Display that is equipped with a high-quality eye tracking system to monitor the subjects’ gaze direction and saccades in real-time. Despite evaluation reveals no outstanding winner, the local magnification effect by Dorr et al. performed the best with up to 30 % target-directed saccades within the first second.
