Janina & APA,

I took an action to look into the implications for screen magnification 
software, when the Pointer Lock API is used. Specifically, what happens 
when a pointerlockchange event is fired - engaging/disengaging the mouse 
as a control for the online environment (such as orientation within an 
online game).

I filed an issue against Pointer Lock on behalf of APA [1]. The 
conclusion is that this is a browser implementation issue - so there is 
a limit to how prescriptive the spec itself can be. The spec can advise 
implementors on important behaviours though, and so the following note 
will now be included before the spec moves to PR:

"Note: Magnification software increases the size of content on the 
screen. It uses the mouse to move the magnified point of focus around. 
When a pointer
lock is initiated, the magnification software needs to switch to using 
the keyboard to move the magnified point of focus around instead. When a 
pointerlockchange
event is fired, web browsers therefore need to make sure the event is 
communicated to assistive technologies like screen magnifiers."

I won't be at the APA meeting on Wednesday. With my WP chair's hat on, 
it would be hugely appreciated if the APA WG could let me know whether 
this solution is agreeable though - because Pointer Lock is currently in 
transition to CR. Thanks.

Léonie.
