Device and method for generating haptic feedback on a planar substrate

摘要

The method involves generating a haptic feedback in form of a perceptible changed rigidity at a point of contact (21) of a planar touch sensitive substrate (2) based on the contact of the planar substrate. The substrate is loaded over an edge area (36) supplementary to the contact burden mechanically or electromechanically on a bend to reduce and load the rigidity of the substrate at the point of contact spaced from the area. The substrate is pre-tensioned against the contact burden in an electromechanical manner. The mechanical contact burden in the area of the substrate is measured. An independent claim is also included for a device for generating a haptic feedback at a planar substrate.
