Adventure Vision was Entex's second-generation system following the [[Entex Select-A-Game]], released a year earlier in 1981.

==Description==
Control is through a single multi-position [[joystick]] and two sets of four buttons, one on each side of the joystick, for ease of play by both left- and right-handed players. Rather than using an [[Liquid crystal display|LCD]] screen or an external [[television]] set like other systems of the time, the Adventure Vision uses a single vertical line of 40 red [[Light-emitting diode|LED]]s combined with a [[Spinning mirror system|spinning mirror]] inside the casing.<ref name="VGK"/> This allows for an effective screen resolution of 150&nbsp;×&nbsp;40&nbsp;[[pixel]]s.<ref name="VGK"/> The mirror motor draws a great deal of power from the [[Battery (electricity)|batteries]], which can be avoided by using the built-in [[alternating current|AC]] adapter.<ref>{{cite news |last1=Gechter |first1=Frédéric |title=Entex Adventure Vision - tu es si fragile ! |url=https://www.rom-game.fr/news/2414-Entex+Adventure+Vision+-+tu+es+si+fragile+!.html |access-date=29 May 2022 |work=www.rom-game.fr |date=December 22, 2016 |language=fr}}</ref>

== Legacy ==
A similar display technique combining red LEDs with a moving mirror was used by [[Nintendo]] in the 1995 [[Virtual Boy]].

Because of the moving parts used by the system, many units no longer work, with an estimated 100 known operational units left.<ref name="destructoid">{{cite news |title=Bit Museum #4: what the hell is an Entex Adventure Vision? |url=https://www.destructoid.com/bit-museum-4-what-the-hell-is-an-entex-adventure-vision/ |access-date=24 May 2022 |work=Destructoid |date=16 July 2009 |language=en-CA}}</ref>
