Abstract:
NVDA (Non-Visual Desktop Access) is a free, globally accessible screen reader
designed to assist individuals with visual impairments by converting text into
speech to navigate digital content. This study aims to assess the efficacy of NVDA
on reading efficacy and academic performance among visually impaired
individuals. The objectives of the study were to learn about socio-demographic
information, assess reading efficacy through pre- and post-assessments, and
gather suggestions for improving NVDA usage. A quasi-experimental research
design was used, with a sample of 20 participants from Tiruchirappalli district,
all of whom were familiar with NVDA. The study focused on variables such as
age, gender, locality, socioeconomic status, and familiarity with other screen
readers. Data were collected using a self-made questionnaire covering four
domains: socio-demographic information, experiences with assistive technologies,
efficacy of NVDA, and suggestions for improvement. Statistical analysis
was performed using SPSS. The findings showed that NVDA significantly
improved reading efficacy and academic performance among the participants.
However, variations were observed in the extent of improvement, with some
participants reporting greater benefits than others. Suggestions from participants
emphasized the need for enhanced language support and increased compatibility
with other applications. In conclusion, the study demonstrates that NVDA is
effective in improving reading proficiency and academic performance among
individuals with visual impairments. Despite its positive impact, the study also
highlights areas for further improvement to increase the softwareâ€™s usability
and overall effectiveness.
