Towards VR Attention Guidance: Environment-dependent Perceptual Threshold for Stereo Inverse Brightness Modulation

Kurzfassung

In this paper, we propose a new method for attention and gaze redirection, specifically designed for immersive stereo displays. Exploiting the dual nature of stereo imagery, our stimulus is composed of complementary parts displayed for each individual eye. This attracts viewers' attention due to induced binocular rivalry. In a perceptual study, we investigate size- and intensity-related perceptual thresholds of our stimulus for six different real-world panorama images. Our results show that a flexible parameterization allows the stimulus to be perceived even in complex surroundings. To prepare for technical innovations expected in future-generation virtual reality headsets, we used a commercially available head-mounted display as well as a high-resolution dps.
