For this movie, post-produced by Grid VFX, I created all screen content that was used live on-set (websites, chat rooms, world maps, …) and did the set-supervision for all sequences in which a computer was used. For example: when an actor was typing, the pre-recorded text comes up. After the queue of the director, I would press a button on my remote keyboard to trigger the response.
This approach provided lots of freedom to the DOP and director since they did not have to treat these shots as VFX-shots. They could do their regular focus pulls, have reflections in the screens, and make the actors react on the content on screens.
