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.
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.

| 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 | 12 Months |

| Digital Assistive Technology | 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 | 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 |
