Fingerpost helps blind and low-vision people use touchscreens that have no tactile buttons, such as self-service kiosks, ticket machines and appliance panels. Point an Android phone at the screen and say what you want to do. Fingerpost reads the screen, finds the right button, and guides your finger toward it using spoken directions, changing tones and vibration. It checks whether the screen changed after a press and can guide you through tasks one step at a time. The app supports English, Hindi and Spanish, includes payment confirmation and an on-device PIN mode, and is free and open source.
