Abstract
A haptic keyboard of an information handling system comprising a coversheet to identify keys of the haptic keyboard, a contact foil and a piezoelectric element to receive an applied mechanical stress at a first key of the coversheet and generate an electric actuation signal. A processor executing instructions of a haptic smart typing assistance system to detect and anticipate a next letter of a word being typed and a controller to receive an instruction of the anticipated next letter and increasing force required actuate at least one key for a letter adjacent to the anticipated next letter, and to send a response haptic feedback control signal to the piezoelectric element to cause the piezoelectric element to generate a first haptic feedback at the first key if the anticipated next letter is selected and to generate a second haptic feedback if a typographical error is detected.
