Hello,
I would like to know if it were possible to add support for multitouch trackpads with NVDA, similar to its touch screen support, or trackpad support on VoiceOver for Mac OS X. This might be limited to Windows 8 and later.

cc @jcsteh @josephsl: Do you think the touch screen layer could be used for this somehow?

Do you think the touch screen layer could be used for this somehow?

  1. Hooking the device: I'm pretty certain you can't use the touch screen hooking API to hook touch pads. @michaelDCurran, can you confirm? We'd need some API to communicate with these devices. In Windows 10, Windows did standardise some of this, but I don't know whether we can hook it as @josephsl notes. Still, it's an open question. Synaptics does provide an API to access its touch pads, but we'd have to implement support for several different vendor specific APIs.
  2. NVDA code: You could probably reuse the touch tracker stuff to detect gestures, etc.
  3. User experience: The desired UX for touch is a bit different, since touch pads are so much smaller. The view available to explore by touch needs to be much smaller, probably restricted and relative to the current navigator object's parent.

Hi,

I'm in favor of closing this at the moment, not because of technical difficulties but we haven't heard from the original poster in the last five years.

Thanks.

Hi, I agree, this function is extremelly interesting for me too. I search addons for this, but no result. I have Toshuba laptop with excellent touchpad and supporting gestures is famous enhancement for NVDA.
