VR-IOMS Trial Summary

This trial tests the effectiveness of three Virtual Reality-based Intelligent Orientation and Mobility Specialists (VR-IOMSs) in teaching orientation and mobility (O&M) task skills to low vision patients. It will be conducted on two sites, University of Alabama at Birmingham (UAB) and Alabama Institute for Deaf and Blind (AIDB). The same protocol will be used on both sites. UAB will be the sIRB for the trial.

Who is the study for?
This trial is for individuals with low vision who have not had formal orientation and mobility (O&M) training, can hear normally or with correction, aim to improve O&M skills, and have stable late-onset visual impairment. They should be able to perform basic tasks like using a mouse or joystick and walking short distances. People with rapidly progressing eye diseases, aggressive treatments ongoing, congenital impairments, existing mastery of the skills being taught, difficulty speaking English, or a history of seizures/motion sickness cannot join.Check my eligibility
What is being tested?
The study tests three methods for teaching O&M skills to those with low vision: learning from Virtual Reality-based Intelligent Orientation and Mobility Specialists (VR-IOMS), from human specialists in real streets (COMS), or watching educational videos as a control group. The effectiveness will be measured by comparing participants' abilities before and after training in real street evaluations.See study design
What are the potential side effects?
There are no direct medical side effects listed for this trial since it involves educational interventions rather than medications. However, participants prone to motion sickness may experience discomfort with VR use.

Experimental Treatment
Active Control
Placebo Group
Group I: Orientation and Mobility Training with VR-IOMSsExperimental Treatment1 Intervention
Low vision subjects with Orientation and Mobility (O&M) difficulties learning O&M skills from Virtual Reality-base Intelligent O&M Specialists (VR-IOMSs). VR-IOMSs are intelligent, computer-controlled automatic O&M skill training programs in virtual streets.
Group II: Orientation and Mobility Training with COMSActive Control1 Intervention
Low vision subjects with Orientation and Mobility (O&M) difficulties learning O&M skills from human Certified O&M Specialists (COMS) in real streets
Group III: No Orientation and Mobility TrainingPlacebo Group1 Intervention
Low vision subjects with Orientation and Mobility (O&M) difficulties watching low vision education videos and discuss low vision issues not related to O&M with COMSs.
