Depth Perception and Spatial Vision01:15

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:

  • Rehabilitation Science
  • Human-Computer Interaction
  • Ophthalmology

Background:

  • Low vision impacts daily living activities.
  • Current assessments may not fully capture functional limitations.
  • Virtual reality (VR) offers a novel platform for standardized assessments.

Purpose of the Study:

  • To validate virtual reality (VR) activities against real-world activities for low vision assessment.
  • To develop standardized activities of daily living (ADL) in VR.
  • To assess the performance of a broad low vision population in VR.

Main Methods:

  • Recreated a rehabilitation space (kitchen, living room) in VR with photorealistic rendering.
  • Developed 25 standardized activities of daily living (ADL) in VR using Unity.
  • Conducted a validation study comparing VR activities to real-world tasks.

Main Results:

  • The study successfully created and validated VR-based ADL.
  • Photorealistic rendering enhanced the immersion and realism of the VR environment.
  • The developed activities were based on a visual functioning questionnaire.

Conclusions:

  • Virtual reality (VR) provides a viable and standardized method for assessing activities of daily living (ADL) in individuals with low vision.
  • The validated VR activities can be used to create objective performance measures.
  • This approach has the potential to improve rehabilitation outcomes for the low vision population.
