Arduino Powered Gesture Keyboard
Gesture keyboard is a library used to convert accelerometer data to a sequence of characters and sentences.
Federico Terzi build a module using an Arduino Pro Micro, a MPU-6050 as accelerometer and a HC-06 Bluetooth module for sending signals to his laptop. A Python library using Scikit-learn’s SVM (Support Vector Machine) algorithm then translates the motion readings into characters that appear on the screen.
When someone press the first button, the module starts to send accelerometer data to the pc. When the button is relased, the transmission stops.
The entire module gets powered by using a power bank.
The full code of this impressive computer interface is available on Github.
