Haptic based communication method

A communication apparatus comprising:

• a first mobile device and a second mobile device,
• in which said first mobile device comprises an input screen for receiving variable first status indicator data about a user and variable second status indicator data about said user,
• in which said input screen comprises a first icon which is manually movable between different positions on said input screen to input said first status indicator data,
• in which said input screen comprises a second icon which is manually movable between different positions on said input screen to input said second status indicator data,
• in which said first mobile device comprises a vibration pattern generation function for generating a variable vibration pattern representing a variability measure based on inputted first status indicator data and second status indicator data, wherein said vibration pattern generation function is configured to generate a vibration pattern comprising a series of beats, each beat comprising at least two pulses of non-zero intensity, wherein the pulses within each beat are spaced at a first frequency, and said beats are spaced at a second frequency,
• in which said first mobile device comprises a transmission function for transmitting said vibration pattern to said second mobile device,
• in which said second mobile device comprises a receiving function for receiving said vibration pattern from said first mobile device,
• in which said second mobile device comprises a haptic vibration generation function for generating a haptic vibration according to said vibration pattern,
• wherein and in which said vibration pattern generation function changes said vibration pattern by varying said first frequency and/or said second frequency, in response to changes in said variable first status indicator data and/or said variable second status indicator data inputted into said input screen by said user.
