System and method for mood detection via piezo haptic keyboard dynamics

A method for mood identification based on piezo haptic keyboard typing dynamics comprising:

• receiving a user identification, via a processor, associated with a personal typing profile identifying a combination of a plurality of previously recorded haptic hardware typing or touch behavior parameters associated with a user;
• detecting actuation signals from keystrokes of a key via a piezo haptic keyboard controller and providing a haptic feedback control signal to the piezoelectric element of the key;
• measuring current haptic hardware typing or touch behavior parameters describing characteristics of a plurality of deformations of a plurality of piezo electric elements during a mood sensing phase via the piezo haptic keyboard controller operably connected to the plurality of piezo electric elements situated beneath a plurality of keys of a piezo keyboard;
• comparing, via the processor, the user personal typing behavior profile against the currently measured haptic hardware typing or touch behavior parameters to identify a user personal typing behavior profile value change;
• associating the user personal typing behavior profile value change with a mood classification having a mood-based haptic keyboard setting adjustment;
• and
• applying the mood-based haptic keyboard setting adjustment to the haptic feedback control signal to a contact foil layer operably connecting the piezo haptic keyboard controller to one of a plurality of piezo electric elements to cause adjustment to one of the plurality of the piezo electric elements.
