I want to know a name for the type of keyboard filtering where a each time a user enters a character, the rest of the keyboard disables all characters which aren't relevant anymore because no word can be formed which would match the current context.
As an example: the possible inputs are all countries of the world.
- The user is presented with a normal keyboard with all letters from
- The user presses
Hand as a result, all letters of the keyboard are disabled except
U. This is because the only matching countries that can be entered now are H
onduras and H
A real live example of this behaviour with public transportation station names can be found on the ticket machines here in Switzerland as seen here:
What would be the name of such a keyboard or keyboard behaviour?
