VisionWay Accessibility Study for People with Visual Disabilities

This study is looking at how accessible different walking paths are for people with visual disabilities. Participants will be asked to walk a defined pathway through a campus. The main goal is to measure how accessible sidewalks are over a period of 2 hours. You might be able to join if you are at least 18 years old, can give informed consent, and have vision worse than 20/200 (meaning severe or profound visual impairment, or total blindness). Some participants will not use mobility aids, while others will use a cane. The study aims to enroll 100 people, but its current status is unclear.

Study design: This is an interventional study with a planned enrollment of 100 participants. The order of walking paths will be randomized between participants.
What's involved: Participants will be asked to walk a defined pathway through campus. This activity will take place over a period of 2 hours.
Compensation: Not stated in the trial record.
Follow-up: The primary endpoint is measured over a period of 2 hours, which suggests the study activities will be completed within that timeframe.

What this trial measures

PVI accessibility on sidewalksFor a period over 2 hours
Primary objectives are to collect prospective data in PVI groups to define which sidewalk features affect accessibility and how to design an accessibility model able to estimate accessibility. Twenty sidewalk (path) features were scored on a 5-point Likert scale (1 = not important, 5 = very important), and participants indicated the number of additional minutes they would be willing to walk to access a route containing each feature (5-point scale. 1 = up to one minute, to 5 = five or more minutes). A combined score for each feature was determined by summing the two values (for each feature) to generate an overall priority ranking. Higher scores indicate a greater perceived importance.
