What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused

Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests a smartphone-based tool called VisionWay that helps people with visual impairments choose the most accessible walking path before they start walking. Researchers will ask participants to walk different routes on a university campus and rate sidewalk features like potholes, crossings, and obstacles. The goal is to build a model that estimates path accessibility based on what matters most to users.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
a smartphone-based wayfinding tool called VisionWay that analyzes sidewalk accessibility features
What this could lead to
If successful, this tool could help people with visual impairments choose safer, more accessible walking routes independently.
What could go wrong
This is an early-stage study focused on gathering data and designing the tool, so it may not yet lead to a working app. Results depend on participant feedback and may not apply to all environments.
