Some scientists in Tokyo have coupled the feeling of touch to the viewing area of a hologram. They achieve this sense of feeling by sending altering waves of ultrasonic frequencies to the users hand through apertures on the outside of the display area. The hand then senses the correlating temperature and pressure to the affected areas.
Although the demonstration I saw was of a very limited machine that only gave room enough for one hand and had an acute viewing angle, it made me think of the ultimate evolution of video games. It's going to happen. Eventually we will be able to BE the characters we've grown to love.
I'm looking to be characters I've made as well as some from video games, movies, books, tv, and comics. If there's only one good thing about not having worldwide accessible physical v.r. right now I have no earthly idea what that would be.
