Patent attributes
A mobile device, computer program recording medium and method support surreptitious communication with a user via a mobile device via binary tactile inputs and outputs. A communication module of the mobile devices receives a first alphanumeric message that is converted to a first binary coded message that is rendered as first and second vibration outputs that are humanly distinguishable. A touch input component of one of a touch screen and a motion sensor detects a sequential pattern of user touches. Distinguished first and second tactile inputs in the sequential pattern identify a second binary coded message that is converted into a second alphanumeric message. First and second alphanumeric messages are comprised of a combination of characters selected from one or more of: (i) letters; (ii) numerals; and (iii) symbols.
