I have a project about exhibitions timeline shared on touch two screens (one from 1989 to 1999, the second 2000 to 2020).
I created animations for each but it would be great if the two could be synchronised for starting the Hype’s timelines at the same time.
Any suggestions ?
The two systems are Mac mini + ELO 27" touchscreens and the former xStand on each.
Offline for sure not as you at least need a local area network as the devices need to talk to each other. In that case you can run and programm a Socket Server. Pusher is such a service as a SaaS. There are solutions you can run as a service deamon on a local network with connected computers.
This is completely nuts, but you can send data over ultrasonic audio, so if the two computers are nearby and have audio listening / recording capabilities, and are hosted on a local https server (assuming you’re running in Chrome), you could use this: https://quiet.github.io/quiet-js/ (But Max’s suggestion is more robust).
