What is the difference between aDesigner and other accessibility checkers?
Existing checkers mostly check the compliance items described above. For example, there is no tool for visualizing the time it takes to reach each element using voice browsers, nor is there any tool for detecting the problematic parts for low-vision users based on image-processing techniques. aDesigner tries not only to evaluate compliance but goes beyond compliance. aDesigner synchronizes the error location with the browser view position, so an author can easily find out which part of the page has a problem. aDesigner also has effective features for handling ALT texts. (ALT text is used as an alternative text for images, and voice browsers read such ALT texts for the images.) ALT texts are very important for voice browser users, but the proper usage of ALT texts is not widely known. aDesigner tells you if the ALT texts are not being used properly.
