It doesn't do any screen-scraping or video interception. What it uses is the operating systems underlying MSAA (Microsoft Active Accessibility( and UIA (User Interface Automation) subsystems. afik there is no single accessibility system in Linux. GTK has the ATK (Accessibility Toolkit) which I believe a few of the graphical tools hook into. Has anyone on the list used yasr (yet another screen-reader)? I tried this on the Pi and it crashed every ten minutes. yasr uses a pseudo-terminal to keep track of screen-updates and cursor movement etc. Mike On 08/05/2013 21:44, Hart Larry wrote: > Just a speculative thought.
