Hi Art,

As discussed with you and Doug, here is a work IBM has done on 
Pointer/Touch events mapping that could contribute to this work item:


The approach: we started from common user actions: click/tap and swipe 
gesture. We tested each user action on various devices/os/browsers and 
wrote how touch events were generated. Then we identified patterns that 
gave a pseudo code to be implemented.

With mobile enabled applications and increase of desktop touchscreens, 
the javascript framework Dojo Toolkit was looking for a solution to 
handle heterogeneous events (mouse, touch...). As Pointer Events are not 
to be implemented right away in all supported browser by Dojo (desktop 
and mobile), we worked on a shim implementation. That is where our work 
could be usefull: we had to work on how to map Pointer Events with Touch 

You can browse the current implementation here:
