A VideoGame interface (or part of it) based on drawing symbols on the screen with your mouse, controller, or stylus, usually to cast FunctionalMagic.

A SubTrope of SomeDexterityRequired. See also GeometricMagic.

!!Examples:

* ''VideoGame/BlackAndWhite'' uses an interface where you perform miracles by drawing corresponding symbols on the ground.
** The sequel keeps this but also adds the option of using a more traditional interface.
* ''VideoGame/{{Sacrifice}}'' allowed you to navigate through the tactical menus with this, although clicking or using keyboard shortcuts was usually simpler.
* In ''VideoGame/{{Turgor}}'', you do pretty much everything except walking and talking by drawing symbols on the screen and feeding them with energy.
** Even talking to Sisters requires it.
* The PC-version of ''{{Fahrenheit}}'' replaces control stick motion patterns of the consoles with tracing the same patterns with a mouse, effectively making it this.
* Several NintendoDS games:
** ''VideoGame/LostMagic'' makes you cast spells that way.
** ''VideoGame/TheLegendOfZeldaPhantomHourglass'' and ''VideoGame/TheLegendOfZeldaSpiritTracks''
** ''NinjaGaiden'' game uses this for the [[FunctionalMagic ninpo]] spells.
** ''VideoGame/CastlevaniaDawnOfSorrow'' required this to finish off defeated bosses.
** ''VideoGame/TraumaCenter''
** ''VideoGame/{{Scribblenauts}}'' gives a type 3 RealityWritingBook to the player, which can be toggled between this and a keyboard.
* The ''VideoGame/HarryPotter'' video games use this method for spell-casting.
* The gameplay of ''VideoGame/{{Okami}}'' and ''VideoGame/{{Okamiden}}'' revolve primarily around the Celestial Brush Techniques, requiring the player to "paint" symbols on the screen to create various effects such as, among other things, making the sun rise.
* In ''Film/MontyPythonsTheMeaningOfLife'' the LicensedGame, in the section "Live Organ Transplants" you as a surgeon have to cut into a body. It starts out with simple lines, then gets more complex and the last one you have to do is in the image of {{Gumby}}.
* An InUniverse example in ''HeavyRain'': Although this interface is not used by the player, Norman Jayden's ARI does have a consistent motion-control interface.
* ''MetroidPrime'' has another in universe example; using the X-Ray visor (or paying attention to the icons on the weapon display) indicates that Samus switches between different functions and fires her ArmCannon via hand gestures.
* Early versions of ''VideoGame/{{Darwinia}}'' used this system to summon units. This was replaced by default with a menu-based system in later versions.
* ''VideoGame/PokemonRanger: Guardian Signs'' allows you to draw symbols that summon Pokémon you've encountered, particularly Legendaries.
* ''ArxFatalis'' used this for its magic system.
* ''{{Myst}} V'' had you draw symbols on a special slate in order to command the strange creatures that inhabited the worlds you visited. Noted for being frustratingly buggy; it often took several tries for a symbol to be recognised, and it was easy to accidentally draw the symbol that would [[GameBreaker take you to the end of the level]].
* InUniverse, non-VideoGame example: In ''Anime/{{Simoun}}'', the Ri Maajons are graphical patterns drawn in the air with the eponymous aircraft's mystical gems, which, if drawn correctly, bring forth powerful magic.
* Various "Gestures" add-ons for UsefulNotes/MozillaFirefox allow you to browse the web with a SymbolDrawingInterface.
* In the Dream World of the generation V ''VideoGame/{{Pokemon}}'' games, there's a minigame where you have to guide a Sableye in a mine cart to collect gems by drawing symbols representing each platform to jump on.
* InUniverse example: In ''Webcomic/{{Homestuck}}'', Jane uses the Pictionary fetch modus, which means she picks up items by drawing them on a tablet computer.
* [[http://www.youtube.com/watch?v=ZSDbBavHSSg Descension: Depths of De'Mae]]. You draw rune shapes over an area, and a spell is cast on that area. For Lightning spells, the bottom tip must touch the foe, while foes within the area of a triangle spell will take damage.
* A very simple variant appears in TheWorldEndsWithYou; certain pins with [[ShockAndAwe Spark Core]] or [[DishingOutDirt Apport]] psychs require the player to draw a circle on the screen.
