Abstract

Various technologies and techniques are disclosed that improve the operation of accessibility applications. A graphics pipe is provided that can be called in user mode from multiple accessibility programs. A request is received from an accessibility application to access the graphics pipe, and a connection is established. The accessibility application listens to the graphics pipe for particular content of interest and builds a model based on that content. The model is used to deliver content to an end user appropriately. Screen captures can be performed on at least part of the content and then rendered onto another surface.
