The most fantastic input and ouput device in the near future I think is VR.

Virtua Racing or V.R. for short, is a Formula One racing arcade game, developed by Sega AM2 and released in 1992. Virtua Racing was initially a proof-of-concept application for exercising a new 3D-graphics platform under development, the "Model 1". The results were so encouraging, that Virtua Racing was fully developed into a standalone arcade title. Though its use of 3D polygonal graphicswas predated by arcade rivals Namco and Atari, Virtua Racing had vastly improved visuals in terms of polygon count, frame rate, and overall scene complexity, and displayed multiple camera angles and 3D human non-player characters, which all contributed to a greater sense of immersion. Virtua Racing is regarded as one of the most influential video games of all time, for laying the foundations for subsequent 3D racing games and for popularizing 3D polygonal graphics among a wider audience.
