Sending a tap to a Web application through VoiceOver - javascript

I am building a web application for use by visually impaired users to explore SVG diagrams via a tactile printout. In order to allow this I need to calibrate the tactile printout to the image on the device. Thus I need to be able to receive the x and y coordinates of a click when using a screen reader, specifically VoiceOver for iOS.
Using Talkback, I would tap and hold until I hear an audible click and then use my second finger to double tap and send clicks to the application itself from that position.
When using VoiceOver, I understand how to send swipes by tap and holding until a triple bell and then swipe. However, I cannot for the life of me find out how to send a positioned click.
On a side note, I am using Hammer.js.
Any ideas?
Thanks

As far as I can tell, this functionality was supplanted by the interactive drag-and-drop support added to VoiceOver in iOS 11.

multitouch not working as expected in leaflet on desktop

I have tested the map on an ipad and thought that it works so far, now i discover that there is a problem on the pc with multitouch systems
the problem seems to be that leaflet decides internally which events are taken. I couldn't defie touchstart as the event type.
when i watch this demo:
https://leafletjs.com/examples/quick-start/
the following difference results on an iPad and a Windows 10 multi-touch screen. If I keep my finger on the screen, whether on the card or outside, I can still touch on the Ipad, but not on the desktop PC. the screen is blocked.
This must of course not be the case, because it is completely normal that the user of public information systems, e.g. puts one hand on the screen and touches with the other.
how can I fix this issue

How to detect Android Split Screen Resizing from Web View?

We are working on a webpage that is currently having issues with split screen resizing.
When we change the orientation of the page on a mobile browser or do a window resize on a desktop browser, we are able to run the required updates fine because we listen to the resize and orientationchange events that get fired with either type of event.
However, we just realized that with split screen on Android (and possibly split screen on iOS tablets), we aren't triggering any resize events for the window and therefore can't do proper updating of our elements based on the split screen being activated or updated (when the user moves the split).
Is this something we can work around or am I just completely missing some functionality that I should be using?
I have looked around online and haven't found anything related so far that I could use from our JS.
Thanks! Any pointers would be greatly appreciated.
Information about Multi-Window Feature in Android - doesn't go over any possible ways to detect it from a web view though, but looks at it from an Android app dev perspective

How to capture two finger event in javascript on Mac?

I am building a website with reactjs. The main DOM I am using is Canvas and users are allowed to move around the web page with the two fingers gesture on Mac OS. If the user move to the left side of the canvas it will trigger a navigator event on the browser to go back. How can I stop the go back event on browser?
I know I can disable the two fingers swipe gesture in system Trackpad configuration. But I don't want to do that since it doesn't seem like a good solution from users' point of view.

Android: disable pinch zoom and pass event to Flash content

I have a flash application written in actionscript 2.0 that shows vector architectural maps and works perfectly on common web browsers. There are many interactions with javascript functions called by user events on the webpage, such as zooming to a certain x,y point. This event is usually accomplished via the mouse wheel.
Now I have to make sure that the thing works on tablet pc, in particular the Galaxy Tab. The first thing I have to fix is that, obviously, there is no mouse wheel and the user naturally tries to pinch zoom the flash application, with the result of zooming the entire web browser.
What I need is to listen to the multitouch gesture and, when a pinch zoom event is called, disable the default zooming event and call a javascript/flash function that allows my flash app to zoom only the objects that need to be zoomed: in few words, the browser stays still and only a part of the flash zooms in or out.
Consider that I am totally new to Android and that I already have working javascript functions to call flash object functions for the zooming purpose, so I just need to connect them to some android things that tell me when the user tries to pinch zoom in and when he tries to pinch zoom out (and possibly the x,y point of zoom).
Thanks a lot for your help!

Passing a JavaScript call from android to flash is a very very hard task as far as I know.
Not because of android (follow this tutorial http://code.google.com/p/openmobster/wiki/JavascriptBridge to pass a JavaScript call to a web page ), but because of flash securities for local content.
It is not too much of an issue on a local computer, but the flashplayer on android is very very buggy.
I think the best is to try to find an other solution if possible...

How to disable mouse gestures as a developer?

I'm developing a web application and I noticed how irritating mouse gestures can be on it, so, is there a way to disable them (Firefox and Opera particularly)?
Edit: It seems there is some confusion. I'm developing a web based software that has an interface with such complex actions and tasks such as mouse selections, file drag and dropping, a desktop and a Windows Explorer -style filesystem. Whenever I try to select multiple virtual files and move them around, mouse gestures will apply and take me away from the software and navigate to the previous page or do something else nasty. My project is not a website, it's a web application -- mouse gestures are poison to this project.
You don't say you're using a library, but this is a jQuery plugin to detect gestures: http://plugins.jquery.com/project/jGesture
Looking at the source code, looks like it depends on measuring the action b/t mousdown and mouseup ... lotsa math.
And Mozilla offers some event handlers.. https://developer.mozilla.org/En/DOM/Mouse_gesture_events but it has a big Non-standard stamped on it.
the polite thing to do would be to inform users that to take full advantage of your site, they should disable mouse gestures temporarily.
