3-D Again? So Soon?

Why just the other day, a month ago, I noted my own problems with 3-D display technologies and thought that they are doomed (link). That case involved a smartphone to be launched with 3-D images on its screen. Today I read (NYT, “ESPN Drops 3D Channel”) that a 3-D TV venture, ESPN’s, will be headed for techno Walhalla because the public doesn’t want to bother. Confirms what I’ve been seeing and experiencing literally from my late teens, thus for nearly sixty years: people are perfectly satisfied watching entertainment in a two-dimensional projection. Ordinary images provide the human eye sufficient information so that the three-dimensional reality behind them can be easily discerned. Will that stop our innovators from trying again and again and again? Probably not.
