Understanding Blindness
Low-Tech Assistive Technologies
Low-tech AT consists of non-electronic tools that provide essential support for daily tasks.
- Braille Materials: Books, labels, and learning resources printed in Braille enable literacy and written communication [1].
- Tactile Maps and Raised-Line Drawings: Physical representations of spaces and objects help blind individuals navigate and understand spatial layouts [2].
- White Canes: A fundamental mobility aid that assists in obstacle detection and navigation [2].

High-Tech Assistive Technologies
High-tech AT integrates advanced electronics and computing power to support accessibility.
- Screen Readers: Software that converts on-screen text into speech or Braille, enabling access to digital content [3].
- Refreshable Braille Displays: Devices that translate digital information into Braille characters in real time [4].
- AI-Powered Wearables: Smart glasses equipped with cameras and artificial intelligence to recognize objects, read signs, and provide navigation assistance [4].

Software-Based Assistive Technologies
Software solutions enhance digital accessibility and everyday interactions:
- Voice-Controlled Assistants: AI-driven applications that execute commands, provide information, and assist with daily tasks using voice input [5].
- Optical Character Recognition (OCR) Software: Converts printed text into digital formats that can be read aloud or displayed in Braille [5].
- Navigation Apps for the Blind: GPS-based tools that provide real-time voice guidance and detailed street descriptions [6].

Emerging Technologies
Advancements in AI, neuroscience, and wearable technology continue to improve accessibility:
- Retinal Implants: Devices that stimulate the optic nerve or retina to restore partial vision in some cases [7].
- AI Object Recognition: Mobile and wearable devices that identify objects, faces, and text, providing real-time auditory descriptions [8].
- Brain-Computer Interfaces (BCI): Experimental systems that translate brain activity into digital commands, offering new ways for blind individuals to interact with technology [9].
