Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages Any age
- All sexes
- No healthy volunteers
- Child, Adult, Older adult
Study population: The study employs a mixed-methods approach, combining quantitative and qualitative data collection techniques. Quantitatively, surveys and structured questionnaires are administered to a diverse sample of visually impaired participants to assess frequency of AT use, types of devices utilized, and self-reported improvements in mobility. Qualitatively, in-depth interviews and focus group discussions provide deeper insight into user experiences, challenges, and preferences.
Who may be able to join
- any age.
- low vision (visual acuity less than 6/18 but equal to or better than 3/60 in the better eye, even with best correction).
- Regular users (minimum 3 months) of at least one type of assistive technology (traditional, digital, or both).
- Able to communicate verbally or in writing (independently or with assistance).
- Willing to provide informed consent and participate in interviews or surveys.
Who cannot join
- Total blindness (no light perception), as the study focuses on low vision.
- Individuals who have not used any assistive technology for mobility.
- Participants currently enrolled in vision rehabilitation training that could bias the outcomes.
- Those with temporary visual impairment (e.g., post-surgery recovery) rather than permanent low vision.

About this study
This study investigates the influence of low vision assistive technology (AT) on the mobility and independence of individuals with visual impairments. The research aims to explore how various low vision devices, such as electronic travel aids, magnifiers, GPS-based navigation tools, and smartphone applications, impact the ability of visually impaired individuals to move safely and confidently within different environments.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Traditional Assistive TechnologyDiagnostic test
Participants in Group 1 utilize traditional, non-digital assistive devices designed to enhance mobility and spatial orientation
Digital Assistive TechnologyDiagnostic test
Participants in Group 2 use modern, digital assistive technologies specifically designed to improve navigation, orientation, and real-time decision-making for visually impaired individuals
Combined Technology UsersCombination product
Participants in Group 3 use a combination of traditional tools (e.g., cane, magnifiers) alongside modern digital aids (e.g., smart canes, GPS apps). This group is important to examine how integrated usage of both types of technologies

What is being measured
The primary outcome is the main question the study is designed to answer.
low vision Orientation and Mobility (O&M) assessment
A low vision Orientation and Mobility (O\&M) assessment evaluates an individual's ability to navigate their environment, considering their vision impairment. These assessments often involve a combination of observation, interviews, and standardized tests to gauge skills in orientation (understanding one's position) and mobility (moving safely). Scoring systems vary, but they generally aim to quantify the level of support needed and track progress over time
Measured: 12 Months

Who may be eligible to take part?
The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 9 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Pakistan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
low vision Orientation and Mobility (O&M) assessment (time frame: 12 Months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jul 2025.
