ABSTRACT:
A method and system for inputting a character string using a handheld input device, such as a mouse wheel or touchpad. Signals are grouped depending on a change in direction, depressing the mouse button as an interrupt, holding a mouse button down, etc., and the groupings are translated into symbols. Translation can be pre-determined or from a mapping file. Symbols can be appended into a character string and provided as a password, PIN, credit card, account number, or as other sensitive data.
