Abstract
A user interface () comprises a layered structure defining one or more keys (). The layers can include a top layer (), a base layer (), and an interior layer () disposed therebetween. One or more layers are pliant and can be compressed. Magnetically permeable materials () form a closed loop (). A corresponding coil () is operable with the loop. Electrical properties of the closed loop change in response to user input. A control unit () is then configured to detect a change in the electrical properties when the pliant material is compressed. Where the change is greater than a predefined threshold, the control unit () discharges an energy storage device into the coil to provide a haptic response ().
