[[File:Nintendo-DS-Lite-w-stylus.png|thumb|240px|Nintendo DS touchscreen (bottom) with [[stylus]]]]A [[touchscreen]] is an input device that allows the user to interact with the computer by touching the display screen. The first attempt at a [[handheld game console]] with touchscreen controls was Sega's intended successor to the [[Game Gear]], though the device was ultimately shelved and never released due to the high cost of touchscreen technology in the early 1990s.<ref>{{Cite web |last=Fahs |first=Travis |date=April 21, 2009 |title=IGN Presents the History of SEGA |url=http://retro.ign.com/articles/974/974695p7.html |url-status=live |archive-url=https://web.archive.org/web/20120204000434/http://retro.ign.com/articles/974/974695p7.html |archive-date=2012-02-04 |access-date=2011-04-27 |website=IGN |page=7}}</ref> The first released console to use a touchscreen was the [[Tiger Electronics|Tiger]] [[game.com]] in 1997. Nintendo popularized it for use in video games with the [[Nintendo DS]] and [[Nintendo 3DS]]; other systems including the [[Tapwave Zodiac]] as well as [[Smartphone]]s and the vast majority of [[Personal digital assistant|PDAs]] have also included this feature. The primary controller for Nintendo's [[Wii U]] console, the [[Wii U GamePad]], features an embedded touchscreen. Modern touch screens use a thin, durable, transparent plastic sheet overlaid onto a glass screen. The location of a touch is calculated from the [[capacitance]] for the X and Y [[Coordinate system|axes]], which varies based upon where the sheet is touched. One console that is touchscreen developed by Sony is the [[PlayStation Vita]] which has a 5-inch OLED touchscreen. The [[Nintendo Switch]] features a 6.2 inch touchscreen.
