Summary

This trial will help researchers understand how people judge distance while moving, in order to better understand how eye and neurological defects can impair someone's ability to do so.

Who is the study for?
This trial is for adults and children over 18 with good stereo vision (sharp depth perception) and normal or corrected-to-normal eyesight. It's not suitable for those with physical movement issues, pregnant women due to the time needed, or anyone with a history of eye diseases.
What is being tested?
The study tests how well people can judge the location of objects at intermediate distances while moving. Participants will be exposed to visual stimuli that challenge their space perception in a controlled three-dimensional environment.
What are the potential side effects?
Since this trial involves only visual stimuli without any drugs or invasive procedures, side effects are minimal but may include temporary eye strain or headaches from focusing on visual tasks.
