People with low vision with visual acuity of (20/70) to 20/180) or significantly reduced visual arc (tunnel vision) have problem with reading standard print of paper as well as web pages. This user group requires an alternative reading environment that can provide changes in size, leading, color, field of view and navigability. Many assistive technologies exist today to meet these issues. Examples include, but are limited to, large screen monitors, screen zoom tools, trackers and color transformers to help the reading process. Purpose of this thesis is to build a product that will solve this reading problem for low vision user group that has low visual acuity.

Solution to this problem is to come up with a dynamic tool that will allow users to attack specific region of web pages. A tool that will allow them to extract and modify the appearance of these areas, based on individual needs. With this idea, author came out with a solution Zone-Clipper. The author is unaware of any benefits this might produce for individuals with a limited visual arc.

Zone-Clipper is an extension to Mozilla Firefox browser. With simple user interface, Zone-Clipper allows users to select specific areas of web page and extract them to modify for reading purpose.
