Visual search engines can enable students, both learning disabled or not, to quickly judge if a web site will have information that is useful for their project. A visual search engine allows one to get past misleading meta data, or meta tags that are used to describe the keywords and content of webpages for search engines.
A visual search engine also makes it easy for teachers who are trying to teach their students which websites are more likely to have the information they need.
The visual search engine content will be governed by the parent controls and filters you use in your home or school. For instance if your school blocks YouTube the students will not be able to see content from YouTube.
Below is a link to a visual search engine I regularly recommend in consultations.
