Methods and systems for determining screen-reader use

Abstract:

Methods, systems, and/or devices for determining that a user uses an assistive-technology program (such as a screen reader) for interacting with a web-based service are described. In some embodiments, this includes identifying a trigger event transmitted from a browser on a client device and identifying an inconsistency in the trigger event that correlates with use of an assistive-technology program in conjunction with the browser on the client device. In response to identifying the inconsistency, the method, system, or device may flag a user of the client device as a user of the assistive-technology program; and in response to flagging the user of the client device as a user of the assistive-technology program, provide content that is compatible with the assistive-technology program to the client device.
