System for providing haptic feedback across full palm rest in fixed position of information handling system

A keyboard, and combination touchpad and palm rest haptic response system of an information handling system, comprising:

• a coversheet to identify a key location of a haptic keyboard, and a combination haptic touchpad interface and palm rest area on a C-cover for the information handling system;
• a haptic combination touchpad and palm rest piezoelectric element based feedback assembly disposed beneath the haptic combination touchpad interface and palm rest area and secured to the C-cover;
• a haptic keyboard piezoelectric element based feedback assembly disposed beneath the haptic keyboard and secured to the C-cover;
• a keyboard controller to receive a keyboard piezo actuation signal from a keyboard piezoelectric element and send a keyboard haptic feedback control signal to the keyboard piezoelectric element to cause the keyboard piezoelectric element to generate a keyboard haptic feedback at the key location;
• and
• a palm rest and touchpad controller to receive an actuation signal from a touchpad and palm rest piezoelectric element and either send a touchpad haptic feedback control signal to generate a touchpad haptic feedback signal or to send a palm rest haptic feedback control signal to generate a palm rest haptic feedback at the touchpad and palm rest piezoelectric element at an actuation location depending on force applied to the combination haptic touchpad interface and palm rest area meeting a threshold level.

• a haptic combination touchpad and palm rest piezoelectric element based feedback assembly disposed beneath the haptic combination touchpad interface and palm rest area and secured to the C-cover, further comprising:
• a touchpad and palm rest contact foil placed between the coversheet and a touchpad and palm rest support layer;
• the touchpad and palm rest piezoelectric element placed between the touchpad and palm rest contact foil and the touchpad and palm rest support layer to receive an applied mechanical stress at the location within the haptic combination touchpad and palm rest area and generate the touchpad piezo actuation signal;
• a haptic keyboard piezoelectric element based feedback assembly disposed beneath the haptic keyboard and secured to the C-cover;
• a keyboard controller to receive a keyboard piezo actuation signal from a keyboard piezoelectric element and send a keyboard haptic feedback control signal to the keyboard piezoelectric element to cause the keyboard piezoelectric element to generate a keyboard haptic feedback at the key location;
