Looking for help,
We have 11 tablets , 10 of which the public are handed and 1 which is the tour guide. They will all be connected to a local WLAN (no internet just for sharing/control). The 10 tablets will have the same presentation/app installed and running, which will consist of a number of pages as a free to explore touch screen presentation, and another group of pages that are just slides with no user control (similar to a powerpoint presentation) which only start when the tour guide starts his talk. The tour guide tablet will have just the slides with next and previous buttons or numbered, and an additional button to exit the presentation.
When the guide talk starts his tablet controls the public tablets, so when he selects say slide/page 1 all the other tablets follows and so on. When the tour/talk is over the guide presses the stop button (which he can at any time) and tells all the other tablets to return to the free to use pages.
In summary it’s just commands from 1 tablet to others across a wifi network to tell them which page to go to.
