Zoom interaction on mobile phone breaks slide in SL360 version, works fine in SL2
Mar 26, 2018
Hi, I've been running into an issue with zoom regions published in SL 360 when accessed via a mobile phone (this issue is not happening in SL2).
Once the zoom region on the slide has been zoomed into, the user may "break the slide" by accidentally touching the screen on the mobile phone: Touching the screen changes the position of the zoom, and the user is not able to re-focus into the designated zoom region anymore. Worst case would be if the user misses a crucial navigation button that is not available anymore after accidentally touching the screen.
Please note: Slide navigation via gestures has been disabled for this slide. So I assume this could not be responsible for this behaviour.
This issue does not happen when publishing a slide with a zoom region in SL2. The zoom region stays fixed in the SL2 published version, even when the user touches the screen.
I've tested this behaviour by uploading the slides to ScormCloud, and accessing the course on an iPhone as well as on an Android phone. Both phones experience the issue.
I have attached the SL2 and SL360 version of a single slide with a zoom region. The dashed/dotted rectangles in these example files show where the zoom region should be. When testing the 360 version on a mobile phone, the rectangle will be cut off after interacting with the screen once zoomed in.
Any help with this would be much appreciated :-)
