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 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.

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.

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.

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.

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.
