Problems to be overcome in high-tech devices for the visually impaired
1Smith-Kettlewell Eye Research Institute, San Francisco, California.
Summary
This paper explores why many assistive technologies for the visually impaired fail to reach widespread use. It examines factors like training, cost, and human considerations to improve future technology adoption.
Area of Science:
- Assistive Technology
- Human-Computer Interaction
- Disability Studies
Background:
- Numerous assistive technologies for the visually impaired exist, yet many face challenges in practical adoption.
- Common barriers include issues with user training, ongoing maintenance requirements, prohibitive costs, and human factors.
- Historically, high-technology development has focused more on the blind than the partially sighted.
Framework:
- This paper analyzes the critical factors hindering the widespread acceptance of assistive technologies.
- It identifies key challenges in the transition from laboratory development to real-world application.
- The analysis aims to provide insights for overcoming adoption barriers in future technological innovations.
Implementation:
- The study examines practical implementation challenges, including production difficulties and user-centered design.
- It highlights the importance of considering the entire lifecycle of a device, from development to long-term use.
- Examples are drawn from both blind and partially sighted user groups to illustrate diverse challenges.
Implications:
- Understanding these adoption barriers is crucial for developing more successful and accessible assistive technologies.
- Addressing factors like cost, training, and human-centered design can improve technology uptake.
- Future research and development should prioritize solutions that are sustainable, user-friendly, and broadly acceptable.
