Please where can i find articles about Assistive Technology devices or services
Good morning, Alfred. You might want to pay a visit to a Reference Librarian in order to sit down and work together to find an assortment of resources for your research. There is generally a Librarian here every day of the week. In the meantime, the databases I would likely recommend for your topic would be EBSCO Academic Search Complete, EBSO Education Source, EBSCO ERIC, and even the two Psychology databases from EBSCO.
I also recommend using "assistive technology" as one search term, but adding in some other information to narrow your search. For example, "higher education, "special education," "budget," etc.- depending on what your focus for reseach is.
Here is a link to a few very brief tutorials that go into more detail about locating the best database and creating the most effective search queries: http://libguides.neumann.edu/content.php?pid=138917&sid=1188001
