A keyboard that adapts to the user.
Keydrop is a project that aims to create a keyboard that adapts to the user. The idea is to hide the keys which are unlikely to be pressed and display a different key (that is more likely to be pressed) in their place.
This project is a prototype of a keyboard developed for research purposes. It has minimal error checking, and some bugs are possible. There is no warranty, and you use it at your own risk.
The article titled "Keydrop: Dynamic Keyboard Layout for Faster Typing and Fewer Typos" was published in International Journal of Human–Computer Interaction (https://www.tandfonline.com/doi/full/10.1080/10447318.2023.2215624).
To run the application, only a web browser is needed, but installing the application on the phone is recommended.
For code execution following requirements needs to be met:
- Python (for processing data)
- JavaScript
- Node.js
- Quasar Framework (Vue.js)
The testing application is still available at rsusik.github.io/test (works only on cell phone as PWA), but we no longer collect any data.

We conducted an experiment involving 54 participants, to find out if the Keydrop keyboard layout is competitive to the gboard-like QWERTY layout in terms of typing speed and the number of typos. The task was to manually copy English sentences; typos were highlighted and had to be fixed immediately. Results showed that, on average, users type by 6% faster, making 33% fewer typos.
