I would like to create an interaction between what is displayed on the computer screen and a smartphone.
The idea is that the interface that appears on the smartphone serves as a remote control to the content of what there is on the computer screen (a play on the web, for example.)
I think the wireless network is taken into account, but I can not determine how.
On the PC we see a character and on an interface with two arrows smartphone.
By clicking on the arrow keys move the character is made.
You see what I'm trying to do?
