Approaches in Assistive Technology: A Survey on Existing Assistive Wearable Technology for the Visually Impaired

People with visual impairment face a lot of challenges in their daily lives, be it small or big. This is mainly due to the lack of assistance provided by the modern assistive devices in terms of providing self-independence and the cost matching it. The main aim of this article is to research and explore the existing assistive technologies in the domain of visual impairment aid. The main objective of the assistive technology is to provide assistance in the day-to-day tasks, with a simple and wearable design to deliver a better user experience. This paper focuses on different approaches that will help the visually impaired through technology and learn those technologies that leverage a comfortable experience to the user. The primary objective of this survey is to navigate through the different approaches to find out the best suite for the authors in developing their technology.
