Abstract
An electronic device generates mapping information that maps individual symbols of a defined order set of symbols to individual symbols of a random order set of symbols. Symbols of the defined order set of symbols are displayed on a display device arranged adjacent to the mapped symbols of the random order set of symbols, based on the mapping information. A user selection of a symbol of the random order set of symbols is received, and a symbol of the defined order set of symbols that maps to the symbol selected by the user is identified based on the mapping information. The symbol of the defined order set of symbols is provided to an application processed by electronic device as a selection from the user.
