Solid Vision are interactive holographic projections. Seto Kaiba used this phenomenon to create holographic monsters in order to recreate the Experience of Death Penalty Game and enhance games, including Duel Monsters, Dungeon Dice Monsters and Capsule Monster Chess.
Duel Monsters cards contain microchips. When the cards are played in a Battle Box, Dueling Arena, Duel Disk or Duel Runner, the microchip is activated. The data it contains is used to created the Solid Vision holograms. Although not shown in the Battle Box/Dueling Arena, from Duel Disks onward, Solid Vision has the ability to inflict physical damage to the opponent in order to make it more realistic.
In the manga, Kaiba created Battle Boxes which used Solid Vision to enhance Duel Monsters and made a deal with Industrial Illusions to produce them.
During Death-T, Kaiba used Battle Boxes, to create holograms of the monsters Summoned in Duel Monsters and Capsule Monster Chess. Whoever lost a game, would be subject to the Illusion of Death by virtual reality. He tested the Penalty Game on human subjects, finding that the average person went insane after ten minutes of the torture.
Battle Boxes were used for the Duelist Kingdom tournament.
In the anime, Dueling Arenas were used instead of Battle Boxes and Death-T did not happen.
