Adaptive technique for sightless accessibility of dynamic web content
First Claim
1. A method for adaptively improving accessibility of dynamic web content by tracking navigation actions performed by a user on a computer system accessing a webpage, comprising:
- determining a screen reader position of focus on the webpage;
monitoring the webpage for a rendering of dynamic content within the webpage;
detecting the dynamic content rendered subsequent to a rendering of the webpage and at a content position other than the screen reader position of focus; and
inserting an object within the previously rendered webpage at the screen reader position of focus responsive to the dynamic content being rendered, wherein the object has attributes of a background of the website, the object is distinct from the dynamic content, the object is not visible on the webpage, and the object comprises text readable by the screen reader describing the dynamic content.

Abstract
One aspect of the present invention includes adaptive techniques used to render dynamic web content for accessibility software applications, such as screen readers. In one embodiment, an operation for improving webpage browsing with accessibility software includes detecting if an accessibility software application is in use, tracking the position of user focus on the webpage, and presenting information to the user based on the position of user focus on the webpage. In a further embodiment, additional content is rendered on the webpage to screen reader applications, and is placed at the position of the screen reader focus in response to dynamic content appearing or changing on the webpage. This additional content is read by the screen reader to inform the user of the dynamic content change, and/or enable the user to quickly perform a specific action on the webpage.
