BroadBoard

BroadBoard is an on-screen keyboard (IME) designed for people with low vision. Instead of shrinking keys to fit everything on the screen at once, BroadBoard keeps every key big and readable — you simply pan around the keyboard to reach the keys you need, so no key ever has to be small.

• Adjustable keyboard sizes, up to extra large

Installation

Google Play

Setting up the keyboard

After installing, BroadBoard must be enabled and selected as your input method:

1. Go to Settings → System → Languages & input → On-screen keyboard → Manage keyboards
2. Enable BroadBoard
3. Switch to it via the keyboard picker (tap the keyboard icon in the navigation bar, or long-press the spacebar in most apps).

Alternatively, launching BroadBoard from the app tray provides guided links to the correct settings screen and keyboard picker
