input validation

A two-minute demo of SmartKnob View, an open-source input knob built from a brushless gimbal motor, magnetic encoder and round LCD. Closed-loop torque control gives software-defined detents and end stops.

A demo of the 8pen, a gesture-based keyboard replacement for touchscreens that lets users enter text by moving around a circle. It is meant for phones, remotes and game controllers and mimics handwriting.

A Microsoft Research demo from TechFest 2012 of a lab touch system that lets viewers feel the effect of different input latencies, down to about 1 ms. It shows how much more responsive dragging feels compared with typical 100 ms touch delay.

A live performance at AGDQ 2014 in which Super Mario World is made to execute arbitrary injected code, running other games like Pong and Snake on the cartridge. It is done through a TASBot feeding precise controller inputs.

Google ATAP's 2015 introduction to Project Soli, a radar-based sensor on a chip that tracks sub-millimeter hand motions for gesture interaction in small devices.

The original five-minute Dropbox demo video, which presented the product's features before a finished product existed. It was aimed at technical early adopters and became famous as a launch strategy.

A tool-assisted speedrun of Pokemon Yellow on Game Boy Color that uses glitches and frame-precise inputs to make the game execute an arbitrary program. It was later obsoleted by an improved run.

Tom7 explains and demos software that learns to play NES games by finding score patterns in memory and then searching for inputs that raise it. It is the video companion to his SIGBOVIK paper.

SethBling uses Super Mario World glitches to inject and run Flappy Bird code on an unmodified SNES, entering it purely with controller inputs. It was the first time a human completed this kind of exploit by hand.

A tool-assisted speedrun of Pokemon Yellow by MrWint that uses arbitrary code execution to push Game Boy hardware to its limits. Through crafted inputs it injects code and ends up running other programs, such as Tetris, inside the game.

A 3-minute demo of a tiny IOCCC 2012 winning C program that simulates fluid dynamics in an 80x25 terminal, using any text (including its own source) as input. The video shows the simulation running to Handel's Water Music.

Alan Kay demonstrates GRaIL, a graphical input language system from around 1968 in which hand-drawn strokes become boxes, connections and dataflow-style programs.

Tom Scott shows a full-size real-life emoji keyboard built from 14 keyboards and over 1,000 hand-placed stickers, covering all of Unicode 8.

A short demo of the Deep Visualization Toolbox, which shows the activations inside a convolutional neural network as it processes live camera input. Viewers see individual units responding to edges, faces and text.

Gameplay footage of the original 1986 Macintosh version of Dark Castle by Silicon Beach Software. The uploader argues the original is a great game that was tarnished by inferior ports.

A tool-assisted run of Brain Age by TASBot, shown at Awesome Games Done Quick 2016. The bot gives deliberately deranged answers while exploiting the game's error-prone recognition.

A tool-assisted speedrun of Super Mario World that achieves arbitrary code execution through frame-precise controller inputs, finishing in 2:25. It was also performed live on real hardware at AGDQ 2014.

A short demo of a 3D Wayland compositor built with Qt 5 and QtWayland, mapping input to and compositing the output of Wayland applications in a 3D scene, also running on a Raspberry Pi.
