Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

1.8K
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

    • Human-Computer Interaction
    • Virtual Reality Accessibility
    • Assistive Technology

    Background:

    • Effective visual accessibility in Virtual Reality (VR) is critical for users with blindness and low vision (BLV).
    • Designing accessible VR systems is complex due to 3D environments and integration challenges with existing applications.
    • Advancements in Vision Language Models (VLMs) offer new possibilities for VR scene interpretation.

    Purpose of the Study:

    • To address the lack of visual accessibility features in VR for BLV users.
    • To develop and evaluate EnVisionVR, a novel system for VR scene interpretation and interaction.
    • To leverage VLMs for enhanced accessibility in virtual environments.

    Main Methods:

    • Conducted a formative study to identify usability barriers for BLV users in VR.
    • Designed and developed EnVisionVR, integrating a VLM, voice input, and multimodal feedback.
    • Evaluated EnVisionVR with 12 BLV users to assess its effectiveness.

    Main Results:

    • Confirmed the lack of visual accessibility as a significant barrier for BLV users in VR.
    • EnVisionVR demonstrated significant improvements in users' ability to locate virtual objects.
    • The system effectively supported scene understanding and virtual object interaction for BLV users.

    Conclusions:

    • EnVisionVR represents a novel approach to VR scene interpretation for BLV users.
    • The integration of VLMs, voice input, and multimodal feedback enhances VR accessibility.
    • Findings support the potential of EnVisionVR to improve the VR experience for individuals with visual impairments.
