Intermediate Visual Space Perception

Description

The ability to judge the locations of various objects from oneself during self-motion in the intermediate distance range (\~2-25m) is crucial for successful performance of activities of daily living, such as walking and driving. However, little is known about the mechanisms of visual space perception involved in judging distance, the focus of this project, in the planning and/or execution of self-motion in the natural 3D environment. The theoretical knowledge to be gained from this project will contribute to the scientific literature and provide insights into how eye and neurological defects could impair visual space perception, wayfinding, and mobility.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Adults (up to 40 years of age)
  • * Children (18 years and older)
  • * Normal, or corrected-to-normal, visual acuity (at least 20/20)
  • * Stereo acuity (\<20 arc sec).
  • * Self-reported history of visual and eye diseases
  • * Physical movement restrictions.
  • * Vulnerable populations such as pregnant women will be excluded owing to the extensive time commitment required of the subjects.
