Hi,

I've a html5 presentation on a a HD1024 brightsign device (published over brightAuthor). I'm wondering if is there a way to disable multitouch gestures like zoom, pinch, swipe? Only single clicks should be allowed.

Thank you, regards
Sebastian

  Hi,

  I do have the same issue as Sebastian. We use a XT1144 (published over brightAuthor) with a supported élo touchscreen. We tried to disable userscaling in the HTML5 which gets embedded, but it dosent help. The users can still zoom the presentation with two fingers.

  Is there a posibility to reduce to singe clicks? Is there a known workaround?

  Thanks for your support!

  Hi, I've got the following answer from the support team:

  ----------------

  It would have to be a setting in the touchscreen.
  Or, if you built you touch project in just brightauthor, then you wouldn't haven pinch or zoom there.

  -----------------

  So I think it's not possible at the moment:-(

  Sebastian

  Hi Sebastian

  I got an anwser from the support and it worked.

  Basicly you can add following in the CSS Part of your HTML5 file:

  body {
  touch-action: none;
  }

  Here you are going to finde more information about the "touch.action" parameter: https://developer.mozilla.org/en-US/docs/Web/CSS/touch-action

  It worked fine for us!
