Stereoscopic displays

Definition

Stereoscopic displays are visual technologies that create the illusion of depth perception by presenting two slightly different images to each eye. This technique mimics how human eyes perceive depth in the real world, enhancing the immersive experience in multimodal virtual environments. By utilizing this depth information, users can interact more intuitively with virtual objects, leading to better spatial awareness and engagement in simulations and interactive applications.
