- Abstract summary: Visual-impaired communities are one of the hindrances groups to accessing web content access in the world.
Five main problems including access limited by the impairment, usability issues due to lack of design, unavailability of visually impaired-friendly applications, lack of communication, and web navigation issues are the most dominant issues.

- Abstract: Visual-impaired communities are one of the hindrances groups to accessing web
content access in the world. The obstacles encountered by this community in
their current practices and to develop best practice guidelines to overcome the
digital divide in Sri Lanka become gap filling of this domain. A preliminary
survey indicated five main problems including access limited by the impairment,
usability issues due to lack of design, unavailability of visually
impaired-friendly applications, lack of communication, and web navigation
issues are the most dominant pertaining issues. To overcome those issues,
solutions are tested and validated using the Design Science approach. Result
Indicate that significant factors need to be incorporated, ensuring
keyboard-friendly websites, easy accessibility and support with semantic
annotation by adding alternative text for images. Furthermore, use headers to
structure the content correctly, design all forms to support accessibility in
mind including Content developing and designing, navigation, the best colour
combination, Pre-recorded video with the audio facilities, braille support on
the web, the designing option has no significant impact on visually impaired
web users. Introducing a rating widget option to a website identifies the level
of accessibility features availability facilitates, thereby overcoming the
disability digital divide. The results further conclude that a significant
difference exists in websites, with and without the involvement of the visually
impaired community. Semantic web and semantic annotations of the context of
page elements, content serialization, and navigation by special keyboard
commands are also highly influencing the effective use of the web and
increasing the satisfaction level in the website accessing process.

We examine the levels of support for different moderation practices applied to potentially misleading and/or potentially offensive content in web search.
We find that the most supported practice is informing users about potentially misleading or offensive content, and the least supported one is the complete removal of search results.
More conservative users and users with lower levels of trust in web search results are more likely to be against content moderation in web search.

We propose an augmented reality navigation system for visual prosthesis that incorporates a software of reactive navigation and path planning.
It consists on four steps: locating the subject on a map, planning the subject trajectory, showing it to the subject and re-planning without obstacles.
Results show how our augmented navigation system help navigation performance by reducing the time and distance to reach the goals, even significantly reducing the number of obstacles collisions.
