Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Traditional Assistive Technology

Intervention Type DIAGNOSTIC_TEST

Participants in Group 1 utilize traditional, non-digital assistive devices designed to enhance mobility and spatial orientation

Digital Assistive Technology

Intervention Type DIAGNOSTIC_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 Users

Intervention Type COMBINATION_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

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* 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.

Exclusion Criteria

* 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.
