I am a professional writer and insolent keyboard geek, but my typing form is horrible. I dropped into the typing course and, over 1
The operator of YouTube channel 3DPrintedLife shows off his unique creation: a mechanical keyboard that detects your hand position via capacitive touch sensors. It also tracks your letter and word pace as you type in the test, displayed on a small LCD screen. If the keyboard detects that your fingers are too far from the start row, or if your word count is too low and errors too high, it zaps you right through the electrical contacts connected to the T and Y keys. LEDs on the top of the board alert the user when the shock is coming – if you are fast enough you can correct your shape and avoid the shock.
The system is built on a low-cost mechanical Pictek card connected to a Raspberry Pi Zero, which interprets the data from the sensors, runs the “typing game” on the small screen, and manages the shocks. Don’t worry, the shocks are harmless: the builder reused the battery and contacts from a shocking pen (similar to a handshake buzzer) to create the project.
If the keyboard seems sadistic, its principles are sound: Applying pain to unwanted behavior is a well-documented way to change that behavior. (It’s out of favor in psychological and scientific circles right now, because, well, duh.) The software that runs everything is actually pretty impressive in the way it detects hand position and determines when to shock the user.
