Depth Perception and Spatial Vision

Depth Perception and Spatial Vision

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.

Area of Science:

Computer Science
Human-Computer Interaction
Assistive Technology

Background:

Artificial intelligence (AI) integration enhances autonomy for visually impaired individuals.
Existing assistive technologies often lack holistic support for indoor activities.

Purpose of the Study:

Introduce the Visual Impairment Spatial Awareness (VISA) system for comprehensive indoor assistance.
Enhance spatial awareness, navigation, and object interaction for visually impaired users.

Main Methods:

Multi-level approach: AR markers for positioning, neural networks for object detection/tracking, depth data for localization.
Intermediate level: Navigation (obstacle avoidance, pathfinding).
Advanced level: Synthesized data for enhanced spatial awareness and item location, utilizing text-to-speech and speech-to-text for HMI.

Main Results:

VISA system demonstrated efficient indoor navigation and object detection/localization.
Enabled accurate label and text recognition.
Users interacted naturally with minimal effort in simulated environments.

Conclusions:

The VISA system significantly enhances spatial awareness and independence for visually impaired individuals.
The multi-level approach effectively addresses complex indoor navigation and interaction challenges.
AI-powered assistive technology offers a promising pathway for improving the quality of life for the visually impaired.
