Evaluating usability of "the smart vision glasses" for individuals who are visually impaired and totally blind

Individuals who are visually impaired encounter significant challenges in navigation, object recognition, and social interactions. Smart vision glasses (SVG) aim to address these issues by providing real-time assistance. This study evaluates the usability of SVG for individuals who are visually impaired and totally blind.

A 6-month prospective case series with 26 participants was conducted. Usability was assessed through semi-structured interviews, surveys, and modified Difficulties in Recognizing Faces and Emotions and Expectations for Smart Glasses as Assistive Device questionnaires. Both qualitative and quantitative data were analyzed to gauge satisfaction and identify functional challenges.

SVG improved participants' ability to recognize faces, identify objects, and read. However, walking assistance and currency identification posed difficulties, particularly in crowded spaces. Despite these issues, 88.5% of participants rated the device as "satisfactory" or "outstanding."

SVG offer a promising means to enhance independence and quality of life for individuals who are visually impaired. However, improvements in walking assistance and currency identification are needed. Further research is advised to address these limitations.
