I was thinking about projecting images, animation, videos, etc. from a device onto a wall for all in the room to see.

  • Will more walls of the future be like one of those billboards (that presents two or three different images) and could change surfaces?

One side of the surface would be more traditional (i.e., a sheet wall type of surface). The other side of the surface would be designed to be excellent for projecting images onto it and/or for use by Augmented Reality (AR), Mixed Reality (MR), and/or Virtual Reality (VR).

Along these lines, here’s another item related to Human-Computer Interaction (HCI):
