Voice-controlled computer system

Abstract

A voice-controlled computer system comprising a headset with a heads up display (HUD). When the system requires a user to verbally enter a character of an alphanumeric security code the system presents to the user on the HUD a plurality of different pairs of alphanumeric characters each containing a first character and an associated (pseudo) randomly generated second character. The first character of one pair is the code character to be entered, but for security reasons the user is required to verbally enter the second character associated with the code character, not the code character itself. The system deciphers verbal entry of the associated second character as equivalent to entry of the first character.

Dependencies are inferred from the claim text.
