I had a brief memory from childhood come back to me- playing the nintendo ds for the first time and being able to touch the screen to play various games and how blown away I was by it.
Typing this 20 years later on my iPhone, I guess I’ve taken it for granted all this time, but im curious to know how “touch screen” works and how it differs from the old school button pressing interface?

A third way of digitizing data for some large displays, can be cameras in corners pointing at reflectors along the opposite side of the screen. Those can be placed along the edges of existing dry erase boards or projector screens to digitize finger/pen touches. 80″ Smart boards that used room projectors had those installed.
